Ecology and Society, 2009 A key goal in road ecology is to determine which species are most vulnerable to the negative effects of roads on population persistence. Theory suggests that species that avoid roads are less likely to be negatively affected by roads than those that do ...

An amphibian species of concern prefers breeding in active beaver ponds
Ecosphere, 2016 Changes in water availability threaten to reduce suitable habitat for wildlife in the western United States. Ecosystem engineers, such as beavers (Castor canadensis), potentially mitigate the effects of such habitat changes, particularly in stochastic ...

Reproductive Biology and Endocrinology, 2005 Background Gonadal steroids, in particular 5 alpha-dihydrotestosterone (DHT) and 17 beta-estradiol (E2), have been shown to feed back on the hypothalamic-pituitary-gonadal (HPG) axis of the ranid frog.

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Brazilian Journal of Biology, 2017 Sciatic nerve transection (SNT), a model for studying neuropathic pain, mimics the clinical symptoms of “phantom limb”, a pain condition that arises in humans after amputation or transverse spinal lesions.

Integrative Conservation, Volume 4, Issue 4, Page 675-685, December 2025.We demonstrated that Anguilla japonica eDNA concentration was allometrically scaled with their body size in both the laboratory and riverine environments. Integrating body size allometry has the potential to improve population abundance estimates in the field, whereas further clarification is required for understanding eDNA production mechanisms ...

Small Non-coding RNA Expression and Vertebrate Anoxia Tolerance
Frontiers in Genetics, 2018 Background: Extreme anoxia tolerance requires a metabolic depression whose modulation could involve small non-coding RNAs (small ncRNAs), which are specific, rapid, and reversible regulators of gene expression.

Ecology and Evolution, Volume 15, Issue 9, September 2025.The colour of amphibian skin and eyes is the result of light interacting with multiple chromatophores (xanthophores, iridophores and melanophores), leading to challenges when trying to identify which of these cells are involved in colour abnormalities.

Using life history to predict outcomes of conservation translocations of herpetofauna
Animal Conservation, Volume 28, Issue 4, Page 592-606, August 2025.We collected data on key life history traits for all herpetofauna profiled in the IUCN Global Conservation Translocation Perspectives series to examine how life history can predict outcomes and difficulties of conservation translocations. The relationships we found provide important insights for conservation practitioners that can be used in the ...
