Untersuchungen zum Amphibienbestand eines Feuchtgebietes in Osnabrück : mit 2 Tabellen [PDF]

, 2012
Im Rahmen der Projekt-Lehrveranstaltung "Angewandte Biotopforschung" an der Universität Osnabrück wurden im Jahre 1987 in einem kleinen Feuchtgebiet des Osnabrükker Stadtteils Atter Untersuchungen an den dortigen Amphibienbeständen durchgeführt.

Assessing the evidence for treating developmental plasticity and phenotypic flexibility as different phenomena

Functional Ecology, Volume 39, Issue 11, Page 2949-2961, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phenotypic plasticity has long played a central role in eco‐evolutionary theory, but it was not until 20 years ago that it was proposed that the term encompasses two distinct phenomena—developmental plasticity and phenotypic flexibility. While this terminology has since

ZW and XY Sex Chromosomes Drive Rapid and Distinctive Evolution of Sex‐Biased Gene Expression

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Cichlids are a textbook model system of adaptive radiation and a fascinating example of rapid sex chromosome evolution. Yet in these fish, as in most other taxa, the mechanisms causing sex chromosome turnover and the subsequent impact thereof are unknown.

Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Longevity, Age‐Specific Survival, and Mean Generation Time of Rana muscosa: Implications for Conservation of Possibly the Longest‐Lived Ranid Frog

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We examined 22 years of mark and recapture data for an endangered amphibian (Rana muscosa) and estimated longevity, age‐specific survival, and mean generation time. The oldest individual was determined to be at least 21 years old. ABSTRACT Life history strategies vary widely among species and play a vital role in extinction risk, especially in a ...

Growth but Not Corticosterone, Oxidative Stress, or Telomere Length Is Negatively Affected by Microplastic Exposure in a Filter‐Feeding Amphibian

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 8, Page 857-869, October 2025.
ABSTRACT Microplastics (MPs) are of increasing global concern for species inhabiting aquatic habitats. However, the mechanisms behind animal responses to MPs still require comprehensive exploration. Amphibians are the most threatened vertebrate group with most species having a complex life cycle, commonly with an aquatic larval stage.

Migration of amphibians and their Mortality on the road of Knyszyn forest landscape park

Acta Biologica, 2015
Spring migration and mortality of two common amphibian species on the road in one of the landscape parks in north-eastern Poland (Knyszyn Forest Landscpae Park) were studied in the years 2013–2015.

Threatened amphibians of the site of ecological use "Dąbski Pond" [PDF]

, 2012
W latach 2009-2010 przeprowadzono inwentaryzację płazów krakowskiego użytku ekologicznego „Staw Dąbski”. Jej celem było określenie składu i liczebności żyjących tam gatunków, porównanie aktualnych danych z wcześniejszymi oraz ustalenie zagrożeń.

Colour Confusion: Reviewing Ambiguities in the Identification and Classification of Chromatophore Deficiencies Among Amphibians

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.
