Elevation alters outcome of competition between resident and range‐shifting species

Autor: Isaac D. Shepard, Hamish S. Greig, Scott A. Wissinger

Publikováno v: Global Change Biology. 27:270-281

Species' geographic range shifts toward higher latitudes and elevations are among the most frequently reported consequences of climate change. However, the role of species interactions in setting range margins remains poorly understood. We used cage

Species-specific traits predict whole-assemblage detritus processing by pond invertebrates

Autor: Jared A, Balik, Cameron, Leitz, Susan E, Washko, Brittney, Cleveland, Dianna M, Krejsa, Marieke E, Perchik, Alexander, Stogsdill, Mike, Vlah, Lee M, Demi, Hamish S, Greig, Isaac D, Shepard, Brad W, Taylor, Oliver J, Wilmot, Scott A, Wissinger

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 whol

Predators balance consequences of climate-change-induced habitat shifts for range-shifting and resident species

Autor: Scott A. Wissinger, Hamish S. Greig, Zachary T. Wood, Isaac D. Shepard

Publikováno v: The Journal of animal ecologyREFERENCES. 91(2)

While many species distributions are shifting poleward or up in elevation in response to a changing climate, others are shifting their habitats along localized gradients in environmental conditions as abiotic conditions become more stressful. Whether

Sex-Dependent Cold Tolerance at the Northern Invasive Range Limit of Gambusia affinis on Cape Cod, Massachusetts

Autor: Zachary T. Wood, Mitchell R. Paisker, Isaac D. Shepard, Stephen T. Hurley, Vanessa R. Hensley, Michael T. Kinnison

Publikováno v: Copeia. 108

Many invasive species may be constrained in their ability to invade high latitude or elevation habitats due to limits of cold tolerance. However, isolated populations at the edge of these species' geographic ranges may face a combination of strong se

Quantifying predator dependence in the functional response of generalist predators

Autor: Isaac D. Shepard, Kyle E. Coblentz, Mark Novak, Christopher Wolf

Publikováno v: Ecology Letters. 20:761-769

A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web patterns left unexplained by the simplest prey-dependent models. However, for logistical reasons, rati

Quantifying predator dependence in the functional response of generalist predators

Autor: Christopher Wolf, Isaac D. Shepard, Kyle E. Coblentz, Mark Novak

A longstanding debate concerns whether functional responses are best described by prey-dependent versus ratio-dependent models. Theory suggests that ratio dependence can explain many food web patterns left unexplained by simple prey-dependent models.
