Abstract:: Questions: (1) What combinations of overlapping water and heat stress and herbivory disturbance gradients are associated with shifts in interactions between Artemisia tridentata subsp. wyomingensis (Artemisia) and herbaceous beneficiary species? (2) Do interactions between Artemisia and beneficiaries shift from competition to facilitation with increasing stress-disturbance where facilitation and competition are...

Distributed subglacial discharge drives significant submarine melt at a Greenland tidewater glacier

Creator:: Fried, M. J., Catania, G. A., Bartholomaus, T. C., Duncan, D., Davis, M., Stearns, L. A., Nash, J., Shroyer, E., and Sutherland, D.
Abstract:: Submarine melt can account for substantial mass loss at tidewater glacier termini. However, the processes controlling submarine melt are poorly understood due to limited observations of submarine termini. Here at a tidewater glacier in central West Greenland, we identify subglacial discharge outlets and infer submarine melt across the terminus using...

Lesser prairie-chicken fence collision risk across its northern distribution

Creator:: Robinson, Samantha G., Haukos, David A., Plumb, Reid T., Hagen, Christian A., Pitman, James C., Lautenbach, Joseph M., Sullins, Daniel S., Kraft, John D., and Lautenbach, Jonathan D.
Abstract:: Livestock fences have been hypothesized to significantly contribute to mortality of lesser prairie-chickens (Tympanuchus pallidicinctus); however, quantification of mortality due to fence collisions is lacking across their current distribution. Variation in fence density, landscape composition and configuration, and land use could influence collision risk of lesser prairie-chickens. We monitored fences...

A climate of uncertainty: accounting for error in climate variables for species distribution models

Creator:: Stoklosa, Jakub, Daly, Christopher, Foster, Scott D., Ashcroft, Michael B., and Warton, David I.
Abstract:: 1. Spatial climate variables are routinely used in species distribution models (SDMs) without accounting for the fact that they have been predicted with uncertainty, which can lead to biased estimates, erroneous inference and poor performances when predicting to new settings – for example under climate change scenarios. 2. We show...

Quantifying dilution and amplification in a community of hosts for tick-borne pathogens

Creator:: Levi, Taal, Keesing, Felicia, Holt, Robert D., Barfield, Michael, and Ostfeld, Richard S.
Abstract:: Recent controversy over whether biodiversity reduces disease risk (dilution effect) has focused on the ecology of Lyme disease, a tick-borne zoonosis. A criticism of the dilution effect is that increasing host species richness might amplify disease risk, assuming that total host abundance, and therefore feeding opportunities for ticks, increase with...

Body size affects individual winter foraging strategies of thick-billed murres in the Bering Sea

Abstract:: 1. Foraging and migration often require different energetic and movement strategies. Though not readily apparent, constraints during one phase might influence the foraging strategies observed in another. For marine birds that fly and dive, body size constraints likely present a trade-off between foraging ability and migration as smaller bodies reduce...
