The distribution of Rana temporaria L. (Amphibia) in an acidified and a non-acidified region of Norway

Fauna Norvegica
The common frog Rana temporaria L. was absent from a poorly buffered, anthropogenically acidified, inland area (Solhomfjell) of Southern Norway where the pH values of ponds and lakes ranged from 4.3 to 4.8 and the Ala concentration was usually below 150

A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa

Ecology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species. We conducted a systematic review to: compile literature on anuran uses in Africa; identify the species and ecoregions involved; and ...

Competition's Role in Shaping Cryptic Genetic Variation

Evolution &Development, Volume 28, Issue 1, March 2026.
Novel and stressful environments can lead to the expression of previously cryptic genetic variation. Using spadefoot tadpoles, we show that the expression of cryptic genetic variation depends on interacting environmental factors, such as diet and competition, suggesting that it contributes to evolutionary change only under specific environmental ...

Integrating the Microbiome Into Infection Ecology and Evolution in Wild Animals

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Parasites are a ubiquitous force in nature threatening wildlife populations and ecosystems. Interactions between hosts and their parasites are impacted by host‐associated microbiomes, which are essential for host development, physiology and immunity.

River‐Floodplain Metacommunities as Complex Networks: The Interplay of Species Interactions, Dispersal, and Environment

Environmental DNA, Volume 8, Issue 1, January–February 2026.
A network‐based framework reveals how species interactions, environmental conditions, and dispersal shape heterogeneous river‐floodplain metacommunities. Using spatiotemporal eDNA data, Bayesian network learning, and graph theory, we identify sub‐communities and key connector species, highlighting mechanisms of dynamic community assembly and informing ...

Multiple Threats Have Overlapping Impacts Across Ecological Levels in Freshwater Ecosystems

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Changes driven by climate change, biological invasion, land‐use change, pollution and overexploitation are decreasing the resilience of freshwater ecosystems worldwide. While the impact of these threats is widely recognised, a critical gap remains in systematically quantifying their relative effects across ecological levels, which is essential

Waving Through Ontogeny: The Larval Chondrocranial Development of Staurois parvus

International Journal of Zoology, Volume 2026, Issue 1, 2026.
The vertebrate skull is a complex structure with diverse evolutionary and developmental patterns. Anuran chondrocranial development has been shown to deviate from generalized vertebrate trends, highlighting its evolutionary flexibility. This study investigates the chondrocranial development of Staurois parvus, a ranid frog, to provide insights into ...

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.

Alternative Splicing and Gene Expression Variation Underlie Population and Life History Differences in an Amphibian

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Populations along anthropogenic disturbance gradients exhibit phenotypic differences, yet the mechanisms underlying these variations remain unclear. By examining gene expression and alternative splicing in wood frogs, we found significant life stage and population‐specific transcriptomic differences, though only two genes (HSP70 and Gpsm2) showed ...
