Kirtland's warbler is one of many conservation-reliant species listed under the Endangered Species Act (ESA). This species has met recovery goals, but removing it from the protections of the ESA is problematic because of its reliance on ongoing conservation. We define conservation management agreements (CMAs) and describe how they may provide a mechanism to protect conservation-reliant species after delisting. We suggest that CMAs should include four major elements: (1) a conservation partnership capable of implementing management actions at conservation-relevant scales, (2) a conservation management plan based on the management actions in the species' successful recovery plan, (3) sufficient financial resources to provide the required conservation management, and (4) legal enforcement. We use the efforts of the Kirtland's Warbler Recovery Team as a case study of the application of CMAs to build and maintain public and private partnerships to ensure continuing management for this species after delisting. © 2012 by American Institute of Biological Sciences.

Aggregate signature algorithms combine n signatures on n different messages from n distinct users into one aggregated signature. The aggregated signature allows the verifier to authenticate the n signatures simultaneously. Because the total signature length and authentication costs are significantly reduced, aggregate signature algorithms are attractive to applications with resource constraints and applications requiring efficient batch authentications. In this paper, we propose a novel aggregate signature scheme based on certificateless-PKC. Under this novel scheme, the length of the aggregated signature and the pairing computation cost in the aggregate signature verification process are independent of the number of signatures being aggregated. We also prove that the proposed scheme is existentially unforgeable against adaptive chosen-message and chosen-identity attacks, based on the hardness assumption of the computational Diffie-Hellman problem. The new scheme will be suitable for resource-constrained applications. © 2016 John Wiley & Sons, Ltd.

Top-down control by spider predators on grasshopper herbivores can produce trophic cascades, which may enhance plant biomass and alter plant community composition. These trophic level effects may be the result of either predator reduction in prey numbers (i.e., consumptive effects) or decreased prey foraging time in response to predator presence (i.e., non-consumptive effects). However, predator-prey interactions can be context dependent and do not always affect the plant trophic level. We conducted a field and laboratory experiment in a Northern Wisconsin (USA) old field ecosystem to uncover whether consumptive or non-consumptive effects of spider predation on grasshopper herbivores result in a trophic cascade, and if so to determine the underlying mechanisms that drive these trophic cascades. In a field experiment, four treatments examined the effects of multiple trophic-level interactions on plant biomass: 1) control treatment of vegetation only, 2) a two trophic-level interaction (grasshoppers and vegetation), and two different three trophic-level interactions: 3) the presence of "predator spiders" to examine consumptive effects, and 4) "risk spiders" with their chelicerae disarmed with beeswax to examine non-consumptive effects. In addition, a lab experiment was conducted to examine behavioral responses by grasshoppers in the presence of both an armed-spider predator and a risk spider to assess whether food quality (high vs low C:N ratios) had an effect on this interaction. Both risk and predator spiders decreased the impact of grasshoppers on plant biomass in the field experiment, and equally reduced overall grasshopper survival, indicating a non-consumptive effect. At the behavioral level, grasshoppers exhibited anti-predator behavior at the expense of reduced food intake. Food quality had no effect on the survival of grasshoppers as foraging was sacrificed for predator avoidance. Taken together, our results indicate that the resulting trophic cascade was the result of non-consumptive effects and that spider presence alone may reduce grasshopper herbivory rates. © 2015, Bio-One.

Batterers intervention programs (BIPs) constitute a primary intervention for perpetrators of intimate partner violence (IPV). There is little understanding as to what elements are necessary for a good intervention program. We conducted 36 individual semi-structured interviews with professionals working with BIPs. Our results yielded three thematic categories: (1) optimal BIP structure—group size and program duration should foster change and interaction, (2) facilitator characteristics—co-facilitation is ideal, and facilitators should have IPV training, and (3) program approaches–programs should challenge their clients on their behavior, promote an environment of safety and openness, and strive to adapt to clients. © 2016 Springer Science+Business Media New York

In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean = 0.34°C decade-1) between 1985 and 2009. Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, leading to the counterintuitive result that regional consistency in lake warming is the exception, rather than the rule. The most rapidly warming lakes are widely geographically distributed, and their warming is associated with interactions among different climatic factors - from seasonally ice-covered lakes in areas where temperature and solar radiation are increasing while cloud cover is diminishing (0.72°C decade-1) to ice-free lakes experiencing increases in air temperature and solar radiation (0.53°C decade-1). The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes. © 2015.

BACKGROUND: Acquired thrombotic thrombocytopenic purpura (TTP) is a potentially fatal disease in which ultralarge von Willebrand factor (UL-VWF) multimers accumulate as a result of autoantibody inhibition of the VWF protease, ADAMTS13. Current treatment is not specifically directed at the responsible autoantibodies and in some cases is ineffective or of transient benefit. More rational, reliable, and durable therapies are needed, and a human autoantibody-mediated animal model would be useful for their development. Previously, TTP patient anti-ADAMTS13 single-chain variable-region fragments (scFv's) were cloned that inhibited ADAMTS13 proteolytic activity in vitro and expressed features in common with inhibitory immunoglobulin G in patient plasma. Here, pathogenicity of these scFv's is explored in vivo by transfecting mice with inhibitory antibody cDNA. STUDY DESIGN AND METHODS: Hydrodynamic tail vein injection of naked DNA encoding human anti-ADAMTS13 scFv was used to create sustained ADAMTS13 inhibition in mice. Accumulation of UL-VWF multimers was measured and formation of platelet (PLT) thrombi after focal or systemic vascular injury was examined. RESULTS: Transfected mice expressed physiological plasma levels of human scFv and developed sustained ADAMTS13 inhibition and accumulation of unprocessed UL-VWF multimers. Induced focal endothelial injury generated PLT thrombi extending well beyond the site of initial injury, and systemic endothelial injury induced thrombocytopenia, schistocyte formation, PLT thrombi, and death. CONCLUSIONS: These results demonstrate for the first time the ability of human recombinant monovalent anti-ADAMTS13 antibody fragments to recapitulate key pathologic features of untreated acquired TTP in vivo, validating their clinical significance and providing an animal model for testing novel targeted therapeutic approaches. © 2016 AABB.

Wetlands Ecology and Management | Year: 2012

Invasive common reed (Phragmitesaustralis) can rapidly form expansive, near-monotypic stands, and thereby lower plant diversity and change marsh habitat structure. Consequently, North American wetland managers often use herbicides, such as glyphosate-based AquaNeat ® and imazypr-based Habitat ®, to control its establishment and spread. However, herbiciding might indirectly affect benthic community structure by directly altering habitat structure, and habitat alterations may vary with herbicide and concentration. These effects may be particularly pronounced ≥1 year post-herbiciding when dead above-ground biomass collapses and submerges. To evaluate how herbicide-caused alterations in habitat affect key trophic linkages, we compared snail and epiphytic algal assemblages, and habitat conditions, among 20- × 20-m replicated plots of reed treated with either AquaNeat ® (30 % solution), Habitat ® (5 % solution), or left herbicide-free (i. e., controls) in an eutrophic Lake Erie coastal marsh 1-y post-herbiciding. Both herbicides equally reduced reed above-ground growth by >90 % relative to controls. Fossaria spp. and Gyraulus parvus snails were more abundant in herbicide-treated plots than in controls, but Shannon-Wiener diversity was similar (H′ ≈ 1. 0) across treatments. All snails collected were pulmonates, suggesting habitat drying might be driving assemblage structure. Snails were denser in plots with metaphyton (mostly Spirogyra) than without, and metaphyton was more abundant in herbicide-treated plots with higher incident light levels and warmer water temperatures than in controls. Snail biomass was positively related to amount of benthic macro-organic matter but not epiphytic algal biomass, which was similar among treatments. Diatoms dominated algal communities in all treatments. In June, Navicula spp. was dominant in controls, whereas Nitzschia palea and Aulacoseira italic, and Nitzschia spp., were dominant in AquaNeat ® and Habitat ® treatments, respectively. However, algal and diatom assemblages were similar in treatments by early-July when marsh water levels significantly decreased and nitrate levels were <1 μg/L. Marsh hydrologic patterns may mediate herbiciding's indirect effects on trophic structure. © 2012 Springer Science+Business Media B.V.

Long-term management planning for conservation-reliant migratory songbirds is particularly challenging because habitat quality in different stages and geographic locations of the annual cycle can have direct and carry-over effects that influence the population dynamics. The Neotropical migratory songbird Kirtland's warbler Setophaga kirtlandii (Baird 1852) is listed as endangered under the U.S. Endangered Species Act and Near Threatened under the IUCN Red List. This conservation-reliant species is being considered for U.S. federal delisting because the species has surpassed the designated 1000 breeding pairs recovery threshold since 2001. To help inform the delisting decision and long-term management efforts, we developed a population simulation model for the Kirtland's warbler that incorporated both breeding and wintering grounds habitat dynamics, and projected population viability based on current environmental conditions and potential future management scenarios. Future management scenarios included the continuation of current management conditions, reduced productivity and carrying capacity due to the changes in habitat suitability from the creation of experimental jack pine Pinus banksiana (Lamb.) plantations, and reduced productivity from alteration of the brown-headed cowbird Molothrus ater (Boddaert 1783) removal programme. Linking wintering grounds precipitation to productivity improved the accuracy of the model for replicating past observed population dynamics. Our future simulations indicate that the Kirtland's warbler population is stable under two potential future management scenarios: (i) continuation of current management practices and (ii) spatially restricting cowbird removal to the core breeding area, assuming that cowbirds reduce productivity in the remaining patches by ≤41%. The additional future management scenarios we assessed resulted in population declines. Synthesis and applications. Our study indicates that the Kirtland's warbler population is stable under current management conditions and that the jack pine plantation and cowbird removal programmes continue to be necessary for the long-term persistence of the species. This study represents one of the first attempts to incorporate full annual cycle dynamics into a population viability analysis for a migratory bird, and our results indicate that incorporating wintering grounds dynamics improved the model performance. © 2016 British Ecological Society.

Foldamers provide an attractive medium to test the mechanisms by which biological macromolecules fold into complex three-dimensional structures, and ultimately to design novel protein-like architectures with properties unprecedented in nature. Here, we describe a large cage-like structure formed from an amphiphilic arylamide foldamer crystallized from aqueous solution. Forty-eight copies of the foldamer assemble into a 5-nm cage-like structure, an omnitruncated octahedron filled with well-ordered ice-like water molecules. The assembly is stabilized by a mix of arylamide stacking interaction, hydrogen bonding and hydrophobic forces. The omnitruncated octahedra tessellate to form a cubic crystal. These findings may provide an important step towards the design of nanostructured particles resembling spherical viruses.

A decline in Lake Erie water levels in 2000 from historic high levels of the 1990s has facilitated a shift in coastal wetland vegetation from open-water floating-leaf plant communities to emergent communities often dominated by the invasive perennial grass, Phragmites australis. Dense, near monotypic stands of this grass may lead to the loss of native plants and reduce suitable habitat for waterfowl and other wetland birds. To assess avian response to this shift in plant community structure, we conducted bird surveys (June-August, 2007) across four vegetation types in two coastal wetlands in the western basin of Lake Erie. Phragmites habitat had higher overall bird abundance but contained the lowest species diversity (H' = 0.71) of the four habitat types. Of the 35 species observed across habitat types, 4 species: (1) red-winged blackbird (Agelaius phoeniceus); (2) tree swallow (Tachycineta bicolor); (3) barn swallow (Hirundo rustica); and (4) bank swallow (Riparia riparia), accounted for 94% of total bird abundance. Ninety-four percent of all birds observed in sampled plots of Phragmites were red-winged blackbirds, and 73% of the total bird abundance (all species) across habitats occurred in Phragmites. This was mostly attributed to the large roosts (>500 birds/50-m radius plot) of red-winged blackbirds in sampled plots of Phragmites. Phragmites community overlap (Ro), represented by Horn's index, varied from a low of 0.30 with floating-leaved vegetation to a high of 0.69 within the Typha (cattail) community. Our results suggest that Phragmites does influence bird abundance and species diversity, but caution is warranted without additional data on nest success and survival.

Purpose: This paper seeks to examine two humanitarian information coordination bodies. The goals of both coordination bodies are the same, to find mechanisms for multiple organizations, engaged in humanitarian relief, to coordinate efforts around information technology and management. Despite the similarity in goals, each coordination body has taken a different path, one toward defining the problem and solution in a more technical sense and the other as defining the problem and solution as more organizational in nature. Design/methodology/approach: The paper develops case studies of two coordinating bodies using qualitative methodologies. Findings: The data suggest that coordination bodies which pursue problems requiring low levels of organizational change are more likely to have visible successes. Coordination bodies that pursue a more challenging agenda, one that aims for information management or management of information technology in ways that require organizational change, are likely to face greater challenges and experience more failures. Research limitations/implications: The paper only examines two coordination bodies at one point in time thus claims can not be made about all coordination bodies and all information coordination efforts. Originality/value: In a time where coordination bodies are seen as an answer to the problem of information sharing during disasters, it is essential to gain understanding concerning the success of these efforts. © Emerald Group Publishing Limited.

Due to the flexibility of wireless mesh networks (WMNs) to form the backhaul subnetworks, future generation networks may have to integrate various kinds of WMNs under possibly various administrative domains. Aiming at establishing secure access and communications among the communication entities in a multi-domain WMN environment, in this paper, we intend to address the cross-domain authentication and key agreement problem. We present a light-weight cross-domain authentication and key agreement protocol, namely CAKA, under certificateless-based public key cryptosystem. CAKA has a few attractive features. First, mutual authentication and key agreement between any pair of users from different WMN domains can be easily achieved with two-round interactions. Second, no central domain authentication server is required and fast authentication for various roaming scenarios is supported by using a repeated cross-domain algorithm. Third, no revocation and renewal of certificates and key escrow are needed. Finally, it provides relatively more security features without increasing too much overhead of computation and storage. Our analysis shows that the proposed CAKA protocol is highly efficient in terms of communication overhead and resilient to various kinds of attacks. © 2015 Springer Science+Business Media New York

Electrospinning has garnered special attention recently due to its flexibility in producing extracellular matrix-like non-woven fibers on the nano-/microscale and its ability to easily fabricate seamless three-dimensional tubular conduits. Biosyn®, a bioabsorbable co-polymer of glycolide, dioxanone, and trimethylene carbonate, was successfully electrospun into tubular conduits for the first time for soft tissue applications. At an electric field strength of 1 kV cm -1 over a distance of 22 cm (between the Taylor cone and the collector) and at a flow rate of 1.5 ml h -1 different concentrations of Biosyn/HFP solutions (5-20%) were spun into nanofibers and collected on a rotating mandrel (diameter 4 mm) at 300 and 3125 r.p.m. Scaffolds were characterized for structural and morphological properties by differential scanning calorimetry and scanning electron microscopy and for mechanical properties by uniaxial tensile testing (in both the circumferential and longitudinal directions). Biosyn® tubular scaffolds (internal diameter 4 mm) have been shown to exhibit a highly porous structure (60-70%) with a randomly oriented nanofibrous morphology. The polymer solution concentration directly affects spinnability and fiber diameter. At very low concentrations (≤5%) droplets were formed due to electrospraying. However, as the concentration increased the solution viscosity increased and a "bead-on-string" morphology was observed at 10%. A further increase in concentration to 13% resulted in "bead-free" nanofibers with diameters in the range 500-700 nm. Higher concentrations (≥20%) resulted in the formation of microfibers (1-1.4 μm diameter) due to increased solution viscosity. It has also been noted that increasing the mandrel speed from 300 to 3125 r.p.m. produced a reduction in the fiber size. Uniaxial tensile testing of the scaffolds revealed the mechanical properties to be attractive for soft tissue applications. As the fiber diameters of the scaffold decrease the tensile strength and modulus increase. There is no drastic change in tensile properties of the scaffolds tested under hydrated and dry conditions. However, a detailed study on the biodegradation and biomechanics of electrospun Biosyn conduits under physiological pressure conditions is required to ensure potential application as a vascular graft. © 2011 Acta Materialia Inc.

Background: Studies that have looked at the effectiveness of computerized decision support systems to prevent drugedrug interactions have reported modest results because of low response by the providers to the automated alerts. Objective: To evaluate, within an inpatient computerized physician order entry (CPOE) system, the incremental effectiveness of an alert that required a response from the provider, intended as a stronger intervention to prevent concurrent orders of warfarin and non-steroidal anti-inflammatory drugs (NSAIDs). Design: Randomized clinical trial of 1963 clinicians assigned to either an intervention group receiving a customized electronic alert requiring affirmative response or a control group receiving a commercially available passive alert as part of the CPOE. The study duration was 2 August 2006 to 15 December 2007. Measurements: Alert adherence was compared between study groups. Results: The proportion of desired ordering responses (ie, not reordering the alert-triggering drug after firing) was lower in the intervention group (114/464 (25%) customized alerts issued) than in the control group (154/560 (28%) passive alerts firing). The adjusted OR of inappropriate ordering was 1.22 (95% CI 0.69 to 2.16). Conclusion: A customized CPOE alert that required a provider response had no effect in reducing concomitant prescribing of NSAIDs and warfarin beyond that of the commercially available passive alert received by the control group. New CPOE alerts cannot be assumed to be effective in improving prescribing, and need evaluation.

In wireless sensor networks, clustering is an effective technique to extend the network lifetime. However, in the multi-hop clustering model, if the nodes are uniformly distributed and the clusters are of equal size, the cluster heads closer to the sink have to relay much heavier traffic, leading to the "energy hole" problem. Unequal clustering structures have been proposed to mitigate the "energy hole" problem; but, how to quantify the cluster sizes for the aim of scalability and energy hole avoidance remains as a challenging problem. In this paper, we first investigate the theoretical issues of the unequal clustering strategy in uniformly distributed sensor networks. We then propose a method to construct optimal clustering architecture to minimize the total energy consumption of all sensor nodes. Furthermore, we design simple but effective and distributed protocols for energy-aware cluster-head rotation and routing that achieve even energy consumption among all nodes. Extensive simulations show that the performance of our approach extends the network lifetime in two to three times of the one achieved in the best-so-far unequal clustering-based routing. © 2012 Elsevier B.V.

Each January, athletic trainers who are part of the Eastern Athletic Trainer’s Association come together to celebrate learning and the profession of athletic training at the annual EATA Conference. This year, the 69th installment of the conference took place January 6-9, 2017 at the Loews Hotel in Philadelphia, Pennsylvania. At the awards ceremony this year, John Furtado received the 2017 Cramer Award. This award was developed by Cramer Products in 1966 to provide a method for the Eastern Athletic Trainers' Association to honor those members who have provided excellent leadership in serving the EATA and in doing so, advanced the profession of Athletic Training. The plaque is inscribed “To the Athletic Trainer who, through leadership and excellence, has contributed most significantly to the advancement of the Athletic Training profession.” In order to receive the award, the recipient must meet the following criteria: 1. Current member, in good standing, of the National Athletic Trainers Association. 2. Currently BOC Certified or Certified-Retired Status and in good standing. 3. Ten years EATA membership. 4. Provided service to EATA on a committee, as a committee chair or held an EATA office for a minimum of 3 years 5. Has served as a speaker or presenter at an annual EATA meeting. 6. Demonstrates a history of special organizational efforts on behalf of the EATA. 7. Has greatly enhanced the profession of athletic training in District I or II, and/ or has served the National Athletic Trainers’ Association or any of its entities. Allan Parsells, Public Relations Chairman for the ATSNJ, sat down with Mr. Furtado to talk about his most recent award and his long career as an athletic trainer. AP: Mr. Furtado, thank you for taking the time to speak with me and congratulations on receiving the Cramer award from the EATA. How did you first get into Athletic Training? JF: I have a Bachelor of Science in Physical Therapy from Northeastern University and Master of Science in Exercise Science and Health Promotion from California University of Pennsylvania. AP: What is your educational background? JF: I expected athletic training while a senior in high school working alongside my high school's athletic trainer, Paul Pelquin. Paul Pelquin was my first mentor for the profession of athletic trainer. AP: Who are your athletic training mentors in New Jersey? JF: My mentors in this state were Dick Malacrea, Mike Goldenberg and Tim Sensor. Before New Jersey, Frank George was a great influence on who I am as an athletic trainer today. AP: What would you say is your greatest accomplishment as an athletic trainer? JF: So far in my career my great accomplishment as an athletic trainer was serving the ATSNJ as their President. It was a great honor to represent New Jersey as an Executive Board member for District 2 and meeting with numerous politicians on promoting athletic training and issues on health topics relating to athletic training. AP: Where have you been employed and in what capacity? JF: I have been employed in Massachusetts at Hawthorne Physical Therapy for 3 years as a physical therapist and the last year as athletic training/physical therapist working at Dartmouth High School in Dartmouth, MA along with working in the clinic. For the last 20 years I have been employed at Princeton University as athletic trainer/physical therapist. I have worked with many sports including men's hockey for the entire time. I am also working with non-varsity undergraduate and graduate population to provide physical therapy services through University Health Services. AP: What advice do you have for those young professionals in athletic training that are reading this article? JF: Do not wait to get involved in volunteering for the promotion of athletic training. Ask your leaders in the state and district level about how can you get involved. You will be the future of our profession and if you do not step up who will. The profession of athletic training has come a long way and we need to keep moving in the right direction. Do not be afraid for our leaders will guide you in formulating the tools you will need to become a future leader. AP: What do you feel is the key to longevity in the profession of athletic training? JF: Athletic trainers need to have a positive outlook along with flexibility to change with the times. I feel the setting I am in makes me feel young being surrounded with young and for the most part healthy individuals. AP: What emotions did you experience when you were awarded the Cramer award? JF: I was stunned, shocked and humbled. The past winners have molded the profession of athletic training from the beginnings where we did not have certification to the time we were considered as an Allied Health Care profession. Sharing this award with my mentor Frank George also make me speechless, for he was the second NATA president, past District 1 director and NATA Hall of Fame. So I truly honored to be selected. I am now the 4th athletic trainer from Princeton University with this award as I joined Eddie Zanfrini, Dick Malacrea and Charlie Thompson. AP: How do you advocate for athletic trainers and the profession of athletic training? JF: I have been at Capitol Hill Day for NATA in Washington, DC in 2014, 2015 and 2016. While at Capitol Hill Day, I have met with members from the office of New Jersey's US Senators and my Congressional Representative discussing proposed laws including The Sports Medicine Clarity Act and The Secondary School Athletes' Bill of Rights. In the state of New Jersey as ATSNJ president I met with assemblymen and state senators on several state proposed laws and issues including the revision of the Physical Therapy Practice Act which may have potential to impact the current practice of athletic trainers in the state of New Jersey. AP: Where do you see the profession of athletic training going in the next 5, 10 or 15 years? JF: In 10 years, I see athletic training with a sit at the table as billing providers of healthcare for all active individuals that services are rendered in the clinic/athletic training room. AP: One last question. If you could have dinner with 2 people, dead or alive, who would you invite and why? JF: I would pick Pinky Newell and Victor Vito Recine. Pinky Newell as a national leader as the head athletic trainer for Purdue University who linked the EATA to the NATA. The EATA was founded one year before the NATA. Pinky paved the way for athletic trainers and how we practice today. It would be great to get his insight and his method to our success as a profession. Victor Vito Recine was one of the founders of ATSNJ. ATSNJ started in his kitchen as he invited other athletic trainers to talk about the issues of their time. I would like to know what it took to formulate the ATSNJ and what were the issues of the times. AP: Mr. Furtado, congratulations on receiving the Cramer award. Thank you for taking the time to answer these questions for me. JF: No problem, Allan. Thank you for your time.

34th International Symposium on Remote Sensing of Environment - The GEOSS Era: Towards Operational Environmental Monitoring | Year: 2011

AmericaView is a national consortium of 37 statelevel, university-led institutions and is the current awardee of a competitive grant issued by the United States Geological Survey for the promotion of the use of remotely sensed imagery through education, outreach and research activities. AmericaView's mission involves supporting the utilization of federal public domain aerial and satellite imagery, developing and supporting K-12, undergraduate, and graduate student remote sensing education, applied remote sensing research, and outreach related to the use of remotely sensed data. Because of the unique nature of each state partnership, "StateViews" have the freedom to implement the AmericaView mission in a way that best meets their state's specific education and research needs. All StateViews implement a variety of educational projects, ranging from museum, science fair, and conference displays, to GIS Day exhibits and workshops, to week-long, intensive teacher training in remote sensing, GIS, and GPS. Recently, states have been forming regional partnerships such as the SATELLITES program and an annual Earth Observation Day event, combining resources to leverage and enhance the strengths that each state brings to its educational mission. This paper will showcase materials and courses developed by AmericaView related to remote sensing for K-12, college level and professional development (including on-line training) along with the SATELLITES program and how AmericaView is working with the WETMAAP activity.

We summarize morphometric data collected over a period of 22 years from a natural population of rainforest sifakas (Propithecus edwardsi) at Ranomafana National Park, Madagascar, and we use those data to document patterns of growth and development. Individually identified, known-age sifakas were successfully captured, measured, and released. We found that body segment lengths increased faster during growth than did body mass, with individuals attaining adult lengths earlier than adult mass. Females can begin reproducing before they are fully grown, but this may not be common. With the exception of hand length, we found no significant sex difference in any adult metric including body mass, chest, and limb circumferences, body segment lengths, and canine tooth height; however, body masses of individual females fluctuated more, independently of pregnancy, than did those of males. We found considerable interannual fluctuation in body mass with single individuals differing more within the same season in different years than from season to season in the same year. Such body mass fluctuation may be a consequence of eastern Madagascar's variable and unpredictable environment in which rainfall during any selected month varies from year to year. © 2010 Wiley-Liss, Inc.
