Can Pollination Networks Withstand Species Loss? An Examination of Plant–Hummingbird Interactions and Their Responses to Experimental Removal of a Flowering Plant Species

Creator:: Leimberger, Kara G.
Abstract:: Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...

Drivers and Impacts of a Recent Annual Grass Invasion: Ventenata dubia and Fire in the Inland Northwest

Creator:: Tortorelli, Claire M.
Abstract:: Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...

A taxonomic revision of Astragalus mokiacensis and allied taxa within the Astragalus lentiginosus complex of Section Diphysi

Creator:: Alexander, J. Andrew
Abstract:: North America, with over 400 species of Astragalus (Fabaceae), is one of three major centers of diversity, all of which comprise the majority of the nearly 1750 species of Astragalus worldwide. One of the most diverse species, Astragalus lentiginosus of Section Diphysi, is a polymorphic complex of over 40 varieties,...

Changes in the scholastic background and academic ability of summer school students in the Santa Monica, California, junior high schools is from 1956 to 1962

Creator:: Verge, Arthur Charles
Abstract:: The purpose of this study was to investigate whether or not change has occurred in the scholastic background and academic ability of students attending the junior high school summer sessions of the Santa Monica Unified School District, California, between the years 1956 and 1962. Applying a Fisher and Yates Table...

Cross-cultural Comparison and Relationship of Motor Skills and Executive Function in Children with Autism Spectrum Disorder in Taiwan and the United States

Creator:: Sung, Ming-Chih
Abstract:: Early childhood is a crucial time for the holistic development of a child’s social, emotional, cognitive, and physical needs to build a solid and broad foundation for lifelong wellbeing and learning (Irwin et al., 2007). During this critical period, there is an increased demand for motor skills and executive function...

Supporting children who struggle with self-regulation : the role of early family risk and child care quality

Creator:: Pratt, Megan E.
Abstract:: Children's early self-regulation skills have long-term implications for a variety of academic, social, and health outcomes. Unfortunately, children facing multiple family risk factors (e.g., harsh parenting, economic disadvantage) are more likely to struggle with early self-regulation. Despite early disparities in self-regulation, promising intervention evidence suggests that high quality prekindergarten experiences...

Marine Mass Mortality in a Global Change Context: Impacts on Individuals, Populations and Communities

Creator:: Sullivan Stack, Jenna
Abstract:: Human actions are pushing natural systems into states that have no historical precedent. In response, empirical and theoretical researchers are increasingly focused on developing ways to predict the responses of ecological systems to change. However, significant knowledge gaps remain, often leading to “ecological surprises” where observed impacts of global change...

Forage production, dual use potential, and trait variation in chicory grown in the Pacific Northwest

Creator:: Seeno, Elizabeth
Abstract:: Grasslands in the Pacific Northwest are characterized by seasonally wet, acidic soils that mainly support cool season grasses and a limited number of legume species. A major limitation to efficient animal production in grass-dominant pastures is the decline in the herbage growth rate and nutritional quality of forage from late...

Strengthening school readiness for children at risk : evaluating self-regulation measures and an intervention using classroom games

Creator:: Schmitt, Sara A.
Abstract:: In recent years, self-regulation has emerged as a foundational skill for academic success and well-being. Unfortunately, many children enter kindergarten without the self-regulation skills necessary to succeed. Children from high-risk backgrounds (e.g., low-income) are particularly vulnerable for difficulties in self-regulation development. Given these documented gaps in self-regulation, it has become...

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...
