Attracting Beneficial Insects To Your Farm: A Comparison Of Habitat Modification Strategies, Kelly Rourke
Attracting Beneficial Insects To Your Farm: A Comparison Of Habitat Modification Strategies, Kelly Rourke
Master's Projects and Capstones
Thoughtful planning to enhance diversity in agricultural landscapes can present a multitude of ecological, cultural and economic benefits. Land managers have many options when considering which habitat modification techniques they can implement on their agri-environment schemes. This comparative analysis of 47 peer reviewed journal articles assesses which landscape enhancements are most effective in attracting beneficial insects, namely pollinators and natural enemies to pests. Through biological control, natural invertebrate predators inhibit vegetative pests that can be detrimental to croplands. The promotion of natural enemies can decrease the need for chemical use and maintenance on farms. Pollinators contribute tremendous benefits to crop …
Opportunities And Constraints Of Sierra Nevada Meadow Restoration For The Mountain Yellow-Legged Frog Species Complex, Allie E. Sennett
Opportunities And Constraints Of Sierra Nevada Meadow Restoration For The Mountain Yellow-Legged Frog Species Complex, Allie E. Sennett
Master's Projects and Capstones
Amphibian populations worldwide are experiencing precipitous declines as a result of disease, introduced species, habitat loss, and climate change. The mountain yellow-legged frog (MYLF), once considered the most abundant vertebrate in the Sierra Nevada, has suffered dramatic population declines in recent decades, and implications of their decline include biodiversity impacts throughout this region. Specifically, the distribution of MYLF has severely contracted within their geographic range, with an obvious shift in overall abundance to sites toward the upper reaches of their elevation range. MYLF occupying high-elevation habitats (i.e., lakes and ponds) must overwinter for especially prolonged periods, which decreases their ability …
