Defenses of whirligig beetles against native and invasive frogs [PDF]

open access: yesPeerJ
Many native insects have evolved defenses against native predators. However, their defenses may not protect them from non-native predators due to a limited shared history.

Effects of elevated temperature, reduced hydroperiod, and invasive bullfrog larvae on pacific chorus frog larvae.

open access: yesPLoS ONE, 2022
Climate change and invasive species threaten many ecosystems, including surface freshwater systems. Increasing temperatures and reduced hydroperiod due to climate change may promote the persistence of invasive species and facilitate new invasions due to ...

Combating adult invasive American bullfrog Lithobates catesbeianus [PDF]

open access: yesEuropean Journal of Wildlife Research, 2014
American bullfrog Lithobates catesbeianus is considered as one of the world’s worst alien invasive species. Currently, the species is present over almost all continents and is suspected to cause substantial ecological damage. Knowledge about its population density, as well as catchability of the species with commonly used sampling gear, is very useful ...

Bombardier beetles repel invasive bullfrogs [PDF]

open access: yesPeerJ, 2022
Invasive non-native predators negatively affect native species; however, some native species can survive the predation pressures of invasive species by using pre-existing antipredator strategies or evolving defenses against invasive predators.

Oxalate nephropathy in free-living American bullfrog tadpoles [PDF]

open access: yesDiseases of Aquatic Organisms, 2015
In February 2014, wild American bullfrog Lithobates catesbeianus tadpoles from an artificial pond in the Kyusyu region, Japan, presented with coelomic and subcutaneous edema and erythema within the skin. A pathological examination of 57 tadpoles of American bullfrogs in the region was conducted to evaluate the disease.

Aquaculture enclosures relate to the establishment of feral populations of introduced species. [PDF]

open access: yesPLoS ONE, 2009
Many species introduced by humans for social and economic benefits have invaded new ranges by escaping from captivity. Such invasive species can negatively affect biodiversity and economies.

Invasive American Bullfrogs Age, Body Size, and Sexual Size Dimorphism Geographical Variation in Northwestern China

open access: yesDiversity, 2022
Invasive species impact both the local biota and human economies and are a very serious threat to biodiversity. The American bullfrog was initially introduced into northwestern China and many other sites for aquacultural purposes. Then, the frogs escaped

Using quantitative eDNA analyses to accurately estimate American bullfrog abundance and to evaluate management efficacy

open access: yesEnvironmental DNA, 2022
Biological invasions contribute now more than ever to the global homogenization of fauna and flora. Large‐scale monitoring programs are, therefore, needed to detect incipient invasions and to evaluate management interventions.

A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa. [PDF]

open access: yesEcol Evol
ABSTRACT Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species. We conducted a systematic review to: compile literature on anuran uses in Africa; identify the species and ecoregions involved; and ...
