Signatures of Wild Animal Life in Earth's Landscapes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Animals shape Earth surface processes and landforms by displacing Earth surface materials and by making them more or less susceptible to geophysical processes. Despite increased recognition of the global significance of animal landscape “signatures”, analysis of their magnitude and generality has not been possible until now.

First Record of Microsporidia Infection in the Damselfly Ischnura elegans Larvae: Temperature and Predator Cue Effects on the Host’s Life History

Diversity, 2022
Here, we report, for the first time, a microsporidian infection in laboratory-reared larvae of the damselfly Ischnura elegans. Infected larvae originated from field-collected adult females, which were caught in southern Poland in August 2020 (the second ...

River Connectivity in Dammed Areas Studied Through Environmental DNA Metabarcoding at Community and Species Levels

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The field of environmental DNA (eDNA) is rapidly expanding with established applications in biodiversity monitoring, rare species detection and ecological assessment. However, its potential to evaluate species connectivity in fragmented aquatic systems remains underexplored.

Impact of the Highly Invasive Signal Crayfish (Pacifastacus leniusculus) on Freshwater Macroinvertebrate Communities

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Invasive non‐native species threaten freshwater ecosystems, disrupting the functioning and structure of the food chain and potentially leading to biodiversity loss. As omnivores, crayfish can modify their environment, directly affecting organisms such as macroinvertebrates.

First detection of Aphanomyces astaci and its potential responsibility for mass mortalities of Pontastacus (Astacus) leptodactylus in Greek lakes

Journal of Biological Research - Thessaloniki
Aphanomyces astaci is a pathogen categorized among the 100 worst invasive alien species, responsible for the crayfish plague disease. In the past, many disease outbreaks devastated native European crayfish populations.

Escape rooms: behavioural response of two invasive crayfish species under water decline scenarios

Journal of Limnology
Climate change and invasive alien species pose a significant threat to biodiversity and the survival of native species. This study considered the impact of drought conditions on the escape behaviour through terrestrial dispersal ability of two invasive ...
