Species Richness and Abundance of Benthic Invertebrates Are Multiplied by Beaver (Castor sp.) Activities in Small Floodplains

open access: yesFreshwater Biology, Volume 70, Issue 5, May 2025.
ABSTRACT Beaver activities modify floodplains of small streams fundamentally. Prevailing lotic sections are supplemented with several additional habitats (e.g., ponds, dams and side channels). While there are several investigations into the invertebrate fauna of single beaver‐induced habitats, the ways beavers modify aquatic invertebrate assemblages of

Insight Into Trophic Niche Differentiation in Labeobarbus (Cyprinidae) in the Luhoho Basin (Upper Congo Basin)

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
Six Labeobarbus species occur in the Middle Luhoho, a left‐bank affluent of the Lowa River, including two chiselmouth species (Labeobarbus brauni, L. longidorsalis) and three rubberlip species (L. caudovittatus, L. longifilis, L. paucisquamatus), as well as an intermediate phenotype referred to as the smiling phenotype.

Exploring Bird Gut Microbiota Through Opportunistic Fecal Sampling: Ecological and Evolutionary Perspectives

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
Wetland degradation threatens bird populations, and their intestinal microbiota composition is influenced by local conditions, particularly diet. This pilot study used fecal samples collected from the ground to assess avian gut microbiota via 16S rRNA metabarcoding, revealing significant variations linked to bird traits and environmental factors ...

Relationships Between Aquatic Ecology, Landscapes, Hydrogeology and Hydrochemistry in Great Basin and Mojave Desert Spring Systems USA

open access: yesEcohydrology, Volume 18, Issue 3, April‐May 2025.
ABSTRACT Springs are groundwater‐dependent systems sustaining most of the riparian and aquatic habitat in western North America's deserts. The relationship between hydrogeology and springs is recognized by groundwater hydrologists and ecologists; however, studies integrating these disciplines have focused on site and species‐specific relationships.

Faecal Pellets of the Endangered Amami Rabbit (Pentalagus furnessi) as an Allochthonous Resource for Benthic Macroinvertebrates in a Forest Stream in Amami‐Oshima Island, Japan

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 3, March 2025.
ABSTRACT The endangered Amami rabbit (Pentalagus furnessi), endemic to two Japanese subtropical islands, has a habit of egesting faeces on streambanks in their habitats. We hypothesized that rabbit faeces transported into streams are consumed by aquatic animals.
