Testing differences in thermal tolerance between two amphibians with contrasting invasion abilities

open access: yesFrontiers in Ecology and Evolution
Physiological traits may influence the establishment success of non-native species, yet empirical links between physiology and invasiveness remain limited. The American bullfrog (L. catesbeianus) and the green frog (L.

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

Data Schema Evolution for the Self‐Adaptive Software Domain: A Systematic Mapping Study

open access: yesSoftware: Practice and Experience, Volume 56, Issue 8, Page 1034-1062, August 2026.
ABSTRACT Context Self‐adaptive Software (SaS) is a special category of software systems that enables adaptation at runtime to address new user requirements or changes in its execution environment. This article focuses on a specific category of SaS named SaS2DB, which encompasses systems that require the storage of data in a database. In short, a SaS2DB

Stomach contents from invasive American bullfrogs Rana catesbeiana (= Lithobates catesbeianus) on southern Vancouver Island, British Columbia, Canada

open access: yesNeoBiota, 2013
Invasive alien American bullfrog populations are commonly identified as a pernicious influence on the survival of native species due to their adaptability, proliferation and consequent ecological impacts through competition and predation. However, it has

Accurate detection and quantification of seasonal abundance of American bullfrog (Lithobates catesbeianus) using ddPCR eDNA assays

open access: yesScientific Reports, 2021
The invasive American bullfrog (Lithobates catesbeianus) imperils freshwater biodiversity worldwide. Effective management hinges on early detection of incipient invasions and subsequent rapid response, as established populations are extremely difficult ...

Tuning in the bullfrog ear

open access: yesBiophysical Journal, 1988
When electrical resonances were observed in acoustic sensory cells of lower vertebrates, the hearing research community was presented with the exciting possibility that tuning in the ears of those animals might be explained directly in terms of familiar molecular devices.

Bio‐inspired inorganic/organic semiconductor heterostructure synapses with UV–visible–NIR wavelength‐dependent responses for image recognition

open access: yesInfoMat, Volume 8, Issue 7, July 2026.
This study presents a SnSe2/DNTT heterostructure photonic synaptic transistor that exhibits wavelength‐dependent photoresponses and synaptic plasticity. Operating with low energy consumption, the device extends spectral sensitivity from ultraviolet (UV) to near‐infrared (NIR) wavelengths, significantly enhancing neuromorphic computing performance. When

Frog community responses to recent American bullfrog invasions

open access: yesCurrent Zoology, 2011
Native species may decline quickly when confronted with an exotic species to which they are not adapted. The extent of decline may depend on the abundance of an invader and the length of time since it first arrived in the community (residence time), and ...

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...
