Fish Presence, but Not Hydrological Connectivity, Alters Amphibian and Zooplankton Communities in Kettle Lakes

open access: yesFreshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Fishless lakes, which may harbour higher biodiversity than lakes with fish, are becoming increasingly rare due to fish introductions. Although the impacts of fish introduction are relatively well studied in high‐elevation fishless lakes, previous studies have mainly focused on a single invertebrate community or on a particular life stage of a ...

Landscape and management factors influence the occupancy dynamics of sympatric salamanders in an urban preserve system

open access: yesGlobal Ecology and Conservation, 2019
Conserving amphibian populations living in urban areas is challenging due to a lack of information about urban amphibian natural history, ecology, and responses to habitat management.

Beaver dam analogues increase amphibian breeding occupancy and bat activity

open access: yesRestoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

Streptozotocin induced hyperglycemia in the axolotl

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 567-584, June 2026.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...

The relationship between body and substrate color for Ambystoma altamirani (Caudata: Ambystomatidae) from the Arroyo los Axolotes, Mexico

open access: yesPhyllomedusa: Journal of Herpetology, 2020
The relationship between body and substrate color for Ambystoma altamirani (Caudata: Ambystomatidae) from the Arroyo los Axolotes, Mexico. To determine whether the coloration of Ambystoma altamirani varies and whether the color is related to the color of

Niche partitioning among sexual and unisexual Ambystoma salamanders

open access: yesEcosphere, 2016
Organisms that have ecologically similar sexual and asexual forms present an evolutionary puzzle, as theory predicts that eventually one form should eliminate the other.

Ocean Romance: Japanese Treefrogs Exploit Coastal Pools for Breeding Under Salinity and Habitat Constraints

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Topographical features, including elevation and the distance of pools from the coastline and forest, influenced breeding‐site use in coastal landscapes. Pool characteristics such as area and depth, together with abiotic conditions particularly salinity, as well as dissolved oxygen, and temperature, further shaped breeding‐site suitability and patterns ...

Living on the edge: How do tiger rattlesnakes (Crotalus tigris) navigate a residential golf course development?

open access: yesConservation Science and Practice, Volume 8, Issue 6, June 2026.
Abstract Outdoor recreation and the infrastructure that supports it can impose a wide range of effects on wildlife, and impacts can vary in their severity based on taxa, the surrounding landscape matrix, and the manner in which recreational spaces are managed.

GnRH Protein Levels in Atrazine-Treated Axolotls (Ambystoma mexicanum) [PDF]

open access: yesImpulse: The Premier Undergraduate Neuroscience Journal, 2008
Atrazine is the most widely used agricultural herbicide in the United States and a known endocrine disruptor. In amphibians, it has been shown to cause gonadal malformations, feminization of males, behavioral changes, and immune suppression; however, its

Experiences with the management and breeding of Mexican axolotl (Ambystoma mexicanum), for research and biobanking purposes, in a vivarium

open access: yesFrontiers in Amphibian and Reptile Science
The Mexican axolotl (Ambystoma mexicanum) is widely used in laboratory research around the world, even though it is classified as critically endangered in nature. We review and describe the development of effective management strategies for this species,
