Data from: Modelling the potential efficacy of treatments for white-nose syndrome in bats

Quinn Fletcher, Quinn Webber & Craig Willis
1. The fungal disease white-nose syndrome (WNS) has caused mass mortality in some species of North American bats during hibernation. 2. We use population viability models to test if a hypothetical WNS treatment or management action could facilitate the recovery of WNS-affected little brown myotis (Myotis lucifugus) populations. We modelled scenarios altering three parameters: (1) WNS severity (population growth rate of WNS-affected populations; λWNS); (2) proportion of population treated; and (3) treatment improvement in winter...

Data from: Reproductive isolation caused by azoospermia in sterile male hybrids of Drosophila

Hunter Davis, Nicholas Sosulski & Alberto Civetta
Recently diverged populations in the early stages of speciation offer an opportunity to understand mechanisms of isolation and their relative contributions. Drosophila willistoni is a tropical species with broad distribution from Argentina to the southern United States, including the Caribbean islands. A postzygotic barrier between northern populations (North America, Central America and the northern Caribbean islands) and southern populations (South American and the southern Caribbean islands) has been recently documented and used to propose the...

Dataset for: Phosphorus mobilization from intact soil monoliths flooded under simulated summer versus spring snowmelt with intermittent freeze-thaw conditions

Darshani Kumaragamage, Chamara Weerasekera, Wole Akinremi, Srimathie Indraratne & Doug Goltz
Enhanced phosphorus (P) release from flooded, anaerobic soils have been extensively studied under summer temperatures, but not under cold temperatures with intermittent freeze-thaw events. We investigated the temperature and freeze/ thaw effects during flooding on the release of P to floodwater from soil monoliths (15-cm depth) collected from eight agricultural fields in Manitoba. Soil monoliths were flooded with reverse osmosis water and incubated for 56 d under simulated summer flooding (SSF, 22±1 ℃), or snowmelt...

Phosphorus release from intact soil monoliths of manure amended fields under simulated snowmelt flooding

Darshani Kumaragamage, Angela Concepcion, Wole Akinremi, Saman Dharmakeerthi, Doug Goltz & Srimathie Indraratne
Anaerobic conditions developed in soils with flooding can enhance the release of soil phosphorus (P) to overlying water, but little information is available for soils with a long history of manure application. We examined the P release from manure-amended soils under simulated snowmelt flooding. Intact monoliths from manured (solid-swine, SSM or liquid swine, LSM) and unamended (control) field plots were collected from Carman, Manitoba. Monoliths were frozen for seven days, then thawed, flooded and incubated...

Body mass and hibernation microclimate may predict bat susceptibility to white-nose syndrome

Catherine Haase, Nathan Fuller, Yvonne Dzal, C. Reed Hranac, David Hayman, Cori Lausen, Kirk Silas, Sarah Olson & Raina Plowright
In multi-host disease systems, differences in mortality between species may reflect variation in host physiology, morphology, and behavior. In systems where the pathogen can persist in the environment, microclimate conditions, and the adaptation of the host to these conditions, may also impact mortality. White-nose syndrome is an emerging disease of hibernating bats caused by an environmentally persistent fungus, Pseudogymnoascus destructans. We assessed the effects of body mass, torpid metabolic rate, evaporative water loss, and hibernaculum...
