Shooting Mechanisms in Nature: A Systematic Review.

open access: yesPLoS ONE, 2016
BackgroundIn nature, shooting mechanisms are used for a variety of purposes, including prey capture, defense, and reproduction. This review offers insight into the working principles of shooting mechanisms in fungi, plants, and animals in the light of ...

Successful Transmission and Isolation of a Fungal Pathogen From Wild Frogs to a Captive Amphibian Model Species: Fine Scale Pathogen Genetic Diversity and Infection‐Induced Changes in Skin Bacteria

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
The isolation of Batrachochytrium dendrobatidis (Bd) from low‐load wild amphibians revealed multiple genotypes, including a potential hybrid, highlighting ongoing pathogen genetic mixing in natural environments. Additionally, Bd infection induced skin microbiome shifts in Hymenochirus boettgeri, demonstrating its utility as a model for studying ...

Adaptations of the Vertebrate Retina to Low‐Light Conditions: A Review

open access: yesAnatomia, Histologia, Embryologia, Volume 54, Issue 4, July 2025.
ABSTRACT Vision is a critical sensory modality in vertebrates, enabling diverse adaptations to environmental challenges. This review explores the remarkable adaptations of vertebrate eyes to low‐light environments, such as nocturnal habitats, deep‐sea ecosystems and subterranean niches.

Effects of Pesticide Mixtures on Host-Pathogen Dynamics of the Amphibian Chytrid Fungus.

open access: yesPLoS ONE, 2015
Anthropogenic and natural stressors often interact to affect organisms. Amphibian populations are undergoing unprecedented declines and extinctions with pesticides and emerging infectious diseases implicated as causal factors.

Environmental DNA (eDNA) Quantitative Polymerase Chain Reaction‐Based Assays for Surveying 125 Taxa of Importance to North America

open access: yesEnvironmental DNA, Volume 7, Issue 3, May–June 2025.
We present 125 eDNA quantitative real‐time polymerase chain reaction (qPCR) assays against animal species of importance to North America. We show how these assays were designed and validated to comply with the Canadian national eDNA standards to allow confident eDNA detection for coastal and inland ecological surveys and biosurveillance.

Pan‐amphibia distribution of the fungal parasite Batrachochytrium dendrobatidis varies with species and temperature

open access: yesEcological Monographs, Volume 95, Issue 1, February 2025.
Abstract Batrachochytrium dendrobatidis (Bd) is a globally distributed fungal pathogen of amphibians that has contributed to one of the largest disease‐related biodiversity losses in wildlife. Bd is regularly viewed through the lens of a global wildlife epizootic because the spread of highly virulent genetic lineages has resulted in well‐documented ...

Hydroperiod Influences Tadpole Growth and Development in the Endangered Littlejohn's Tree Frog (Litoria littlejohni)

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
Amphibians globally face significant threats, prompting the need for effective conservation strategies across various life stages. Investigating hydroperiod effects on Litoria littlejohni tadpoles, we exposed them to different water levels over 28 weeks.

Using life history traits to assess climate change vulnerability in understudied species 利用生活史特征评估研究不足物种的气候变化脆弱性

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 368-381, December 2024.
Lack of species information complicates understanding climate change vulnerability, but life history traits can be proxies for missing information. In the north‐central United States, useful traits for discriminating vulnerability of amphibians include range size, clutch size, diel activity patterns, and habitat breadth.

Assessment of Allometry in Environmental DNA and RNA Production From Ayu (Plecoglossus altivelis) in an Experimental Condition Using Mitochondrial and Nuclear Gene Markers

open access: yesEnvironmental DNA, Volume 6, Issue 6, November–December 2024.
We examined the allometric scaling in ayu eNA production at the individual level. We also found that the ratio of some types of eNA concentrations could reflect mean fish body size. Our study offered insights into the production of various eNA particles depending on body size and metabolic rate and implications for a better understanding of the ...

Estradiol action in the female hypothalamo–pituitary–gonadal axis

open access: yesJournal of Neuroendocrinology, Volume 36, Issue 10, October 2024.
Evolution of estradiol action in the hypothalamo–pituitary–gonadal (HPG) axis of females. Left, early HPG axis at the time of Moore and Price and Hohlweg. Middle, refinements to the axis, including the hypothalamus as the main central neural player and the postulated regions of control for tonic and surge gonadotropin release by Barraclough and Gorski.
