A system of components designed for the rapid prototyping of different robot body plans for legged robots is described in this chapter. The components are designed and fabricated using 3-D printing technology. As such, they constitute a low-cost way to experiment with legged robots for researchers, practitioners, and students. As legged robots become more common, there will be a need for new designs and new intelligent behaviors. A system of components that facilitates experimentation can play an important role in this development. And because these components are 3-D printed, they can easily be shared and fabricated by others. © Springer International Publishing Switzerland 2017.

Most recent studies describing pollination networks are based on observed flower visits, and few have explicitly tested if the floral visitors actually carry pollen. Since floral visitors can vary in their ability to remove and transfer pollen, it is important to show that visitation patterns reflect effective pollination. Given the difficulty of measuring per-visit pollen deposition at the community scale, a first step is to examine the amount of conspecific pollen carried by insect visitors. Here I compared the plant-animal visitation network with the pollen-transport network, estimated from insect pollen loads, for a montane meadow community from southern California, USA. Visitation and pollen-transport networks were positively associated with each other in both 2001 and 2002. However, the exclusion of visitors that do not carry any conspecific pollen reveals that pollen-transport networks are more specialized from the plants' perspective and that species are involved in fewer mutualistic interactions compared with estimates derived from visitation frequencies. Although conspecific pollen loads were smaller in 2002, bees tended to carry the largest conspecific loads in both years and were responsible for transporting the most pollen. These results suggest that, although visitation networks are suitable first-order approximations of pollination networks, information on which visitors carry conspecific pollen, and in what amounts, is crucial for distinguishing between antagonistic and mutualistic interactions. © 2009 Oikos.

Structural analysis of plant-pollinator networks has revealed remarkably high species and interaction diversity and highlighted the species important for pollination services. Although techniques to analyze plant-pollinator networks began to emerge a decade ago, the characterization of spatiotemporal variation of interactions is still in its infancy. Understanding the ecological and evolutionary causes and consequences of spatial and temporal variation in plant-pollinator interactions is important for both basic and applied questions in community structure and function, the evolution of floral traits, and the development of optimal conservation strategies. Here we review observational, theoretical, and experimental studies of temporal and spatial variation in plant-pollinator interaction networks to establish a foundation for future studies to incorporate perspectives in spatiotemporal variation. Such perspectives are crucial given the rapid environmental changes associated with habitat loss, climate change, and biological invasions, which we discuss in this context. The inherent plasticity of plant-pollinator interactions and network structure suggests that many species should be able to persist by responding to environmental changes quickly, even though the identity of their mutualistic partners may change. © 2011 Botanical Society of America.

The field of pancreatic stem and progenitor cell biology has been hampered by a lack of in vitro functional and quantitative assays that allow for the analysis of the single cell. Analyses of single progenitors are of critical importance because they provide definitive ways to unequivocally demonstrate the lineage potential of individual progenitors. Although methods have been devised to generate "pancreatospheres" in suspension culture from single cells, several limitations exist. First, it is time-consuming to perform single cell deposition for a large number of cells, which in turn commands large volumes of culture media and space. Second, numeration of the resulting pancreatospheres is labor-intensive, especially when the frequency of the pancreatosphere-initiating progenitors is low. Third, the pancreatosphere assay is not an efficient method to allow both the proliferation and differentiation of pancreatic progenitors in the same culture well, restricting the usefulness of the assay. To overcome these limitations, a semi-solid media based colony assay for pancreatic progenitors has been developed and is presented in this report. This method takes advantage of an existing concept from the hematopoietic colony assay, in which methylcellulose is used to provide viscosity to the media, allowing the progenitor cells to stay in three-dimensional space as they undergo proliferation as well as differentiation. To enrich insulin-expressing colony-forming progenitors from a heterogeneous population, we utilized cells that express neurogenin (Ngn) 3, a pancreatic endocrine progenitor cell marker. Murine embryonic stem (ES) cell-derived Ngn3 expressing cells tagged with the enhanced green fluorescent protein reporter were sorted and as many as 25,000 cells per well were plated into low-attachment 24-well culture dishes. Each well contained 500 μL of semi-solid media with the following major components: methylcellulose, Matrigel, nicotinamide, exendin-4, activin βB, and conditioned media collected from murine ES cell-derived pancreatic-like cells. After 8 to 12 days of culture, insulin-expressing colonies with distinctive morphology were formed and could be further analyzed for pancreatic gene expression using quantitative RT-PCR and immunoflourescent staining to determine the lineage composition of each colony. In summary, our colony assay allows easy detection and quantification of functional progenitors within a heterogeneous population of cells. In addition, the semi-solid media format allows uniform presentation of extracellular matrix components and growth factors to cells, enabling progenitors to proliferate and differentiate in vitro. This colony assay provides unique opportunities for mechanistic studies of pancreatic progenitor cells at the single cell level.

This summer Research Experience for Undergraduates (REU) in Mathematics at California State University Channel Islands will support 12 REU students each of three summers. Unique features include a focus on targeting talented students who might not otherwise have considered mathematics as a viable career choice, particularly those from traditionally under-represented groups, with a special emphasis on students who are native Spanish speakers or first-generation college students. Our group of experienced faculty mentors includes several bilingual (Spanish-English) faculty including one from a partner university in Mexico. We expect the emphasis on native Spanish speakers and students from under-represented groups will broaden the pipeline into graduate school and mathematical careers.

Students will spend the bulk of their time working on research in groups of size four per faculty mentor. Workshops, distinguished visitors and colloquia, exchanges with another regional REU, and social outings are also included in the activities. Our primary goal is for the student participants to conduct original mathematical research leading to publications. In so doing we wish to raise their levels of mathematical maturity and confidence while fostering an enthusiasm for mathematics. We will create and maintain a research community of mathematicians. We will improve the participants abilities to communicate mathematics visually, orally, and in written form. We expect students to leave the program better equipped to pursue their mathematical studies as well as feeling excited and prepared to perform graduate-level mathematics in an academic or industrial setting.

California State University Channel Islands is awarded a grant to plan the development a research station on Santa Rosa Island in Channel Islands National Park. The station will serve as a platform for multidisciplinary research on and stewardship of the unique natural and cultural resources within the park. The facility includes a four acre parcel and several existing buildings that are being renovated to accommodate visiting researchers, as well as undergraduates engaged in research projects on the island. The project will rely heavily on the experience of individuals associated with field stations and existing institutional partners, including the National Park Service, the U.S. Fish & Wildlife Service, and the National Oceanographic and Atmospheric Administration. The grant will support travel and consultation with key individuals at other institutions that have experience developing and operating field research facilities (particularly those located in island settings). The project will allow CSU Channel Islands to develop a long-term strategic plan to guide the research facility?s physical development, its organizational structure, and its programmatic activities.

Santa Rosa Island supports a diverse array of terrestrial animal and plant species. The waters surrounding the island are cold and nutrient rich, with an array of marine life including kelp forests, pelagic fish and numerous marine mammals. Isolation from the mainland fostered allopatric speciation which has yielded numerous endemic species and subspecies. Many of Santa Rosa Island?s endemic species have become endangered over the past century. The current understanding of the earliest colonists to the Americas is based on finds such as the Arlington Man on Santa Rosa Island. The field station will serve as a platform to enable work by researchers and students from a range of disciplines and institutions. Being part of the California State University system, CI is well positioned to foster research and educational partnerships with many of the CSUs other 22 campuses, as well as nearby University of California campuses. As a Hispanic Serving Institution, CI has a special opportunity to use the Santa Rosa facility to engage underrepresented minority students in field-based undergraduate research experiences.

This RAPID project focuses on production and delivery of dry ravel, a characteristic and immediate post-fire response on steep slopes in the western USA. Dry ravel arises from a dry-season transport process whereby gravel sediment moving down hillslopes by gravity becomes trapped by vegetation. This material provides a significant sediment source into river channels after wildfire in chaparral environments. The investigators will quantify the volume of dry ravel sediment deposited along channel margins as a result of the Springs Fire that burned Big Sycamore Canyon in southern California during May 2013. Terrestrial laser scanning before and after the rainy season (which typically begins around October 1) will capture initial changes in landscape topography. These data will be augmented by field surveys. Data collected during the first post-fire year are important for developing models of the dynamics of dry ravel. The investigators have geomorphic data spanning over 25 years for Big Sycamore Canyon and two comparable basins nearby with different fire histories--a tributary to north fork Matilija Creek that burned completely during the July 1985 Wheeler Fire-- and a tributary to Malibu Creek that has remained unburned. Comparing dry ravel processes at these three sites will enable a direct comparison of both short- and long-term sediment dynamics following wildfire in chaparral environments.

Developing a predictive understanding of both short- and long-term effects of wildfire is critical, especially in an era of changing climate that has increased frequencies and magnitudes of wildfires. Yet, accurately predicting post-fire effects remains elusive, and physically-based models of post-fire runoff and erosion are still being developed. The proposed project will integrate research and education by involving undergraduate students from California State University, Channel Islands (CSUCI). These students will pursue their capstone undergraduate coursework while assisting the PIs with field data collection and analysis. Two of these students are participants of the Hispanic-Serving Institutes ACCESO (Achieving a Cooperative College Education Through STEM Opportunities) Research Assistant Program on the CSUCI campus. These students will receive valuable research experiences including training in use of cutting-edge technologies.

The REU in Mathematics at California State University Channel Islands will support 27 REU students conducting mathematical research in Summer 2015 and Summer 2017. Unique features include a focus on targeting talented students who might not otherwise have considered mathematics as a viable career choice, particularly those from traditionally underrepresented groups, with a special emphasis on native Spanish speakers and first-generation college students. The group of faculty mentors includes several bilingual (Spanish-English) faculty. The inclusion of one early-career mathematician from another campus each year will spread the practice of effective undergraduate research mentoring. By inviting native Spanish speakers and first-generation students to join more traditional students, this project creates a model of a diverse, rigorous research environment. Students will tackle original research problems in the areas of algebra, data analysis, graph theory, operator theory, analysis, linear algebra, applied mathematics, and their intersections that are of interest to the mathematical research community yet accessible to students.

Students will spend the bulk of their time working on research in groups of four per faculty mentor; faculty mentors will work with their students an average of 3 - 5 hours per day. Workshops, distinguished visitors and colloquia, and social outings are also included in the activities. The primary goal is for student participants to conduct original mathematical research while raising their levels of mathematical maturity and confidence and fostering an enthusiasm for mathematics. Students will develop mathematical communication skills in visual, oral, and written form. The project will incorporate students into a heterogeneous group with shared intellectual goals. Students will leave the program feeling excited and prepared to conduct graduate-level mathematics in an academic or industrial setting. We expect the emphasis on native Spanish speakers and students from underrepresented groups will broaden the pipeline into graduate school and mathematical careers.


Widespread declines of pollinators are a major concern because of their potential effects on agricultural crops and on reproduction of plants in natural areas. Without pollination many species of plants will be in danger of extinction. Pollinators are especially threatened in landscapes dominated by agriculture. Nonetheless, some native species of bees are able to live in these landscapes and are likely to pollinate a large diversity of flowers. Perhaps they can compensate for the reduction of pollination services provided by non-native honey bees, whose populations are crashing. This EAGER project will survey native bee communities in agricultural landscapes of southern California. Researchers will census areas dominated by blueberry and tomato crops. The primary goal is to determine the environmental factors that best predict which pollinators occur in different areas and which morphological traits best predict their pollination effectiveness. This information will be valuable for conserving and managing populations of native bees to ensure that the pollination services they provide will be available for the greatest number of flowering plants.

This project will provide basic information about pollination, a critically important process in most agricultural crops. The lead investigator is at a four-year Hispanic Serving Institution and undergraduate students from groups traditionally underrepresented in science will be involved in data collection and mentored in field research, enhancing their educational and employment prospects.
