Functional trait diversity determines if ecosystem processes are sensitive to shifts in species abundances or composition. For example, trait variation suggests detritivores process detritus at different rates and make different contributions to whole- assemblage processing, which could be sensitive

AbstractHow bees shift the timing of their seasonal activity (phenology) to track favorable conditions influences the degree to which bee foraging and flowering plant reproduction overlap. While bee phenology is known to shift due to interannual climatic variation and experimental temperature manipu

Polyphenisms occur when phenotypic plasticity produces morphologically distinct phenotypes from the same genotype. Plasticity is maintained through fitness trade-offs which are conferred to different phenotypes under specific environmental contexts. Predicting the impacts of contemporary climate cha

Understanding the factors controlling the relative abundance, distribution, and diversity of organisms is a fundamental challenge in ecology. For plants and animals, macroecological rules have been developed that describe these large-scale distributional patterns and attempt to explain the underlyin

Abstract Insectivorous birds have ecologically important effects on prey abundance, behavior, and evolution, and through top‐down control, birds indirectly reduce herbivory and promote plant growth. While several studies sought to characterize biogeographic patterns in top‐down control by birds, var

The skeletal remains of an adult male individual from the 5JF52 site was analyzed to the extent allowed by the condition of the bony skeleton. The analysis includes a description of the material, dentition, demographic information pertinent to age, sex, stature and race, and a complete analysis of m

Violarite from the Copper King mine, Boulder County, Colo., occurs as a secondary mineral after pentlandite. It is associated with fresh pyrrhotite and with several altered forms of pyrrhotite including secondary pyrite after pyrrhotite. Hence violarite has a much broader stability range in the oxid

The effect of altitude on the distribution of insects has not been widely studied, and except for isolated observations, no work has been done on the vertical distribution of the ground beetles (Carabidae). It is the purpose of this thesis to show the distribution of the Carabidae throughout the alt

We found that rare species, whether at low abundance or with a small range, do not disproportionately contribute to phylogenetic diversity in our subalpine plant community. These results were consistent across elevations. Instead, rare species might provide phylogenetic redundancy with common specie

With global climates changing rapidly, animals must adapt to new environmental conditions with altered weather and phenology. The key to adapting to these new conditions is adjusting the timing of reproduction to maximize fitness. Using a long-term dataset on a wild population of yellow-bellied marm
