Biomass and Bioenergy | Year: 2015
While much research has focused on landowner perspectives for producing biomass to supply potential future bioenergy demands, there has been relatively little research on regional public opinion and perceptions of land use change associated with bioenergy production. This project investigates perceptions of potential bioenergy land use among the general public by using a natural experiment employing narrative frames of agriculture and forestry. Results show differences in public perceptions given these two narrative land use frames. Relatively high levels of uncertainty were found across both frames, especially related to perceptions of future impacts on local energy prices in the forestry frame. Understanding how land use frames can influence perceptions about bioenergy system development can help facilitate more effective communication while addressing potential uncertainties when moderating or participating in stakeholder group deliberation regarding bioenergy and related land use change. © 2015 Elsevier Ltd.

The coupling of diazotized 2-aminothiazole and 2-aminobenzothiazole with cyclohexane-1,3-dione yielded a new type of tridentate ligand system (HL). Analytical, IR, 1H-NMR, 13C-NMR and mass spectral data indicate the existence of the compounds in the intramolecularly hydrogen bonded azo-enol tautomeric form. Monobasic tridentate coordination of the compounds in their [CuL(OAc)] and [ML2] complexes [M = Ni(II) and Zn(II)] was established based on the analytical and spectral data. The Zn(II) chelates are diamagnetic while the Cu(II) and Ni(II) complexes showed a normal paramagnetic moment. © 2014 Copyright SCS.

Biological Invasions | Year: 2012
Cactoblastis cactorum is known for being both a biological control agent and an invasive pest of opuntioid cacti. The spread of C. cactorum in the southeastern United States may threaten the biological and physical integrity of desert, scrub, and coastal habitats. However, the effects of invasive species are known to vary spatially and temporally, and C. cactorum's efficacy as a biological control agent varies considerably from region to region. Therefore, the long term effects of C. cactorum within its U. S. range are still uncertain. Marked Opuntia stricta (n = 253) and O. humifusa (n = 327) plants along the west coast of Florida were censused for 6 years to determine the effects of C. cactorum attack on survival and growth rate of plants, and to examine host species differences and the effects of plant size. 78.1 % of the Opuntia plants were attacked by C. cactorum during the 6 year study and the overall survival rate was 75.8 %. Plants attacked by C. cactorum were more likely to die than unattacked plants and a plant's odds of surviving the 6 year period decreased as C. cactorum attack frequency increased. However, plants that survived the 6 year period showed, on average, positive growth and there was no significant difference in growth rates between surviving attacked and unattacked plants. O. stricta plants were more likely to be attacked at least once, were attacked more frequently, and were more likely to die after being attacked than were O. humifusa plants. Plant size did not predict plant survival, but larger surviving plants lost proportionally more pads over the 6 years than smaller surviving plants. Although C. cactorum should still be considered a threat, particularly for rare opuntioids, overall survival along the west central Florida coast is currently high and plants that are able to survive C. cactorum attack are not being reduced in size, possibly because they possess traits that render them more tolerant of C. cactorum damage. Our findings suggest that an assumption of severe negative effects of an invasive species, based on its effects in other regions or over short periods of time, may not always be justified. © 2012 Springer Science+Business Media B.V.

Diversity | Year: 2011
Many aquatic species have discrete life stages, making it important to understand relative influences of the different habitats occupied within those populations. Although population demographics in one stage can carry over to spatially separated life stages, most studies of habitat associations have been restricted to a single life stage. Among Gomphidae dragonflies (Odonata: Anisoptera), recruitment via adult oviposition establishes initial population sizes of the aquatic larvae. However, spatial variability in larval survivorship could obscure the relationship between adult and larval densities. This study uses surveys conducted during 2005 and 2006 of Gomphidae larval, emergence, and adult stages from 22 lake sites in northern Wisconsin, USA, to investigate (1) whether the Gomphidae density of each life stage correlated spatially with that of the preceding life stage and (2) what habitat factors help explain variation in densities at each life stage. Results indicated that adult densities from the previous season helped predict densities of early-instar larvae. This finding suggests that oviposition site selection controlled the local larval distribution more than larval survivorship or movement. Late-instar larval densities helped predict densities of emerging Gomphidae later the same season, suggesting that variation in survivorship of final-instar larvae among sites is small relative to the variation in larval recruitment. This study demonstrates that locations with higher densities of odonates in the water also have higher densities of odonates on land. In addition to the densities of Gomphidae in previous life stages, water clarity helped predict larval densities, and riparian wetland vegetation helped predict emergent dragonfly densities. © 2011 by the authors.

Zootaxa | Year: 2016
The Western Hemisphere or the New World, also known as the Americas (North, Central and South America, associated islands and included seas) have historically been divided into two Realms, the Nearctic and Neotropical based on terrestrial biogeography. The coasts of these two terrestrial realms are bordered by six marine realms, 14 marine provinces and 67 marine ecoregions. From current literature, a comprehensive list of the marine tardigrade fauna from the Americas is presented. Data on marine tardigrades were obtained from 385 published Records of the Occurrence (RoO) of a species, their location, tidal zone, and the substrates from which they were reported. Authors identifications were accepted at face value unless subsequently amended. Thirty genera and 82 species or subspecies are reported from the Americas; 49 species are documented from margins of the terrestrial Nearctic realm (North America) and 48 from terrestrial Neotropical realm (South America) with only 17 species occurring in both. We define cosmopolitan distribution for marine tardigrades as occurring in or on the margins of five of the seven oceans, only two species of marine tardigrade meets this standard. From the Americas 39 species have been described as new to science, 32 species appear restricted to the hemisphere. Taxa were assigned to marine ecoregions based on adjacent geopolitical units (country, states, provinces, etc.) described in published records. Although tardigrades have been reported from all six marine realms, they are only known from 21 of the 67 ecoregions. Most marine tardigrade sampling in the Americas has focused on near shore substrate (sand, mud, barnacles); for some species no substrates have been reported. The west coasts of both continents have little or no data about tardigrade presence. © 2016 Magnolia Press.
