Linking behavioural variance to environmental heterogeneity: Variance decomposition in surface versus cave isopod populations

Functional Ecology, Volume 39, Issue 3, Page 737-755, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A longstanding question in evolutionary biology is how within‐population phenotypic variation is maintained under natural selection. The fluctuating selection hypothesis suggests that genetic and phenotypic variation scales with fluctuations in selection over space and ...

Assessing the Complex Effects of the Invasive Amphipod Dikerogammarus villosus on Leaf Litter Breakdown in Rivers

Freshwater Biology, Volume 70, Issue 2, February 2025.
ABSTRACT Allochthonous organic matter is an essential resource of aquatic food webs, and freshwater amphipods, particularly species of the genus Gammarus, play a significant role in leaf litter decomposition. However, this important ecological function may be affected by the invasion of alien amphipods such as Dikerogammarus villosus, which has been ...

The Role of Artificial Lakes Located in Forests in the Context of Small Retention, Biodiversity and Climatic Changes—Evidence From Southern Poland

Ecology and Evolution, Volume 15, Issue 1, January 2025.
The model of plant associations showed the occurrence of 24 species of plants within nine plant assemblages in the Phragmitetea and Potametea classes of associations. Despite human activities, lake condition, as assessed by the ESMI index or the biocenotic diversity indices, is good.

Bioaccumulation of palladium, platinum and rhodium from urban particulates and sediments by the freshwater isopod Asellus aquaticus

, 2001
The three-way catalytic converters introduced to oxidize and reduce gaseous automobile emissions represent a source of platinum group elements (PGEs), in particular platinum, palladium and rhodium, to the urban environment.

Seasonal diet pattern of non-native tubenose goby (Proterorhinus semilunaris) in a lowland reservoir (Mušov, Czech Republic)

Knowledge and Management of Aquatic Ecosystems, 2010
The tubenose goby (Proterorhinus semilunaris) is a gobiid species currently extending its area of distribution in Central Europe. The objective of the study was to evaluate the annual pattern of its feeding habits in the newly colonised habitats of the ...

Occurrence of larval Acanthocephalus anguillae (Acanthocephala) in the Asellus aquaticus (Crustacea, Isopoda) from the River Brenta

, 1994
A total of 440 specimens of Asellus aquaticus were collected from the River Brenta (northern Italy) in a single sampling in August 1992, and examined for larval helminth parasites. From the hemocoels of 14 (3.1%) individuals of A.

Species-genetic diversity correlation in a metacommunity of urban pond invertebrates

Basic and Applied Ecology
Understanding patterns of species-genetic diversity correlations (SGDC) is important for conservation purposes because it allows us to infer whether conservation of species diversity (SD) influences conservation of genetic diversity (GD) and the other ...
