Life history traits influence method-specific detection of native and invasive amphibians

Frontiers in Amphibian and Reptile Science
IntroductionEfficient and effective monitoring is essential for informing conservation efforts and determining where to focus management actions. Newly arriving invasive and declining native taxa are often the focus of conservation programs, but these ...

Relative abundance of amphibians in forest canopy gaps of natural origin vs. timber harvest origin [PDF]

, 2010
Small-scale canopy gaps created by logging may retain adequate habitat structure to maintain amphibian abundance. We used pitfalls with drift fences to measure relative abundance of amphibians in 44 harvested gaps, 19 natural treefall gaps, and 36 closed-

Characterization of the toll‐like receptor 13 homologs in American bullfrogs, Lithobates catesbeianus, and their involvement in antimicrobial immunity

Journal of the World Aquaculture Society
Toll‐like receptors (TLRs) are an important family of pattern‐recognition receptors that recognize a series of pathogen‐associated molecular patterns to trigger the host immune response.

Limited role of aquatic habitat complexity in mitigating the ecological impact of invasive bullfrogs on native amphibians

Global Ecology and Conservation
Spatial overlap in habitat use and structural habitat complexity can shape the ecological impact of biological invasions. Environmental conditions that mitigate these impacts can be exploited in nature-based conservation strategies aimed at damage ...
