    Differential Contributions of Olfactory Receptor Neurons in a Drosophila Olfactory Circuit 

    Newquist, Gunnar; Novenschi, Alexandra; Kohler, Donovan; Mathew, Dennis (2016)
    The ability of an animal to detect, discriminate, and respond to odors depends on the functions of its olfactory receptor neurons (ORNs). The extent to which each ORN, upon activation, contributes to chemotaxis is not well ...

    Impacts of growing-season climate on tree growth and post-fire regeneration in ponderosa pine and Douglas-fir forests 

    Hankin, Lacey E.; Higuera, Philip E.; Davis, Kimberley T.; Dobrowski, Solomon Z. (2019)
    We studied the impacts of climate variability on low-elevation forests in the U.S. northern Rocky Mountains by quantifying how post-fire tree regeneration and radial growth varied with growing-season climate. We reconstructed ...

    The mismatch in distributions of vertebrates and the plants that they disperse 

    Dittel, Jacob W.; Moore, Christopher M.; Vander Wall, Stephen B. (2019)
    Little is known about how mutualistic interactions affect the distribution of species richness on broad geographic scales. Because mutualism positively affects the fitness of all species involved in the interaction, one ...

    Orienting the Interaction Compass: Resource Availability as a Major Driver of Context Dependence 

    Pringle, Elizabeth G. (2016)
    Life on earth is enormously diverse, in part because each individual engages in countless interactions with its biotic and abiotic environment during its lifetime. Not only are there many such interactions, but any given ...

    The wind dancer 

    Dell, Jane (2019)
    Thus, these caterpillars also engage in behavioral crypsis. When disturbed, the caterpillar sways slowly from side to side on two prominent prolegs, mimicking a leaf wavering in the breeze. If predation shaped the natural ...

    The genetic legacy of 50 years of desert bighorn sheep translocations 

    Jahner, Joshua P.; Matocq, Marjorie D.; Malaney, Jason L.; Cox, Mike; Wolff, Peregrine; Gritts, Mitchell A.; Parchman, Thomas L. (2019)
    Conservation biologists have increasingly used translocations to mitigate population declines and restore locally extirpated populations. Genetic data can guide the selection of source populations for translocations and ...
