Morphological diversity and relationships of Scardinius dergle and Scardinius plotizza populations (Actinopteri; Cypriniformes) from Croatia and Bosnia and Herzegovina [PDF]

Journal of Central European Agriculture, 2021
Genus Scardinius (Cypriniformes, Actinopteri) belongs to the family Leuciscidae, subfamily Leuciscinae, and it includes 10 species. Phylogenetic and morphometric research conducted so far have shown a great taxonomic complexity within this genus ...

Defining relictual biodiversity: Conservation units in speckled dace (Leuciscidae: Rhinichthys osculus) of the Greater Death Valley ecosystem

Ecology and Evolution, 2020
The tips in the tree of life serve as foci for conservation and management, yet clear delimitations are masked by inherent variance at the species–population interface.

The Interannual Variability of the Fall Size of Young-of-The-Year Chub (Squalius cephalus): Influence of Phenology, Growth Patterns and Abiotic Factors

Frontiers in Environmental Science, 2021
Long-term surveys confirm the rapidity of environmental and biological changes undergone by endangered species but that also concerned relatively “tolerant” species, especially common rheophilic species such as European chub (Squalius cephalus, Linnaeus ...

Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

Journal of Fish Diseases, Volume 49, Issue 12, December 2026.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...

A framework for investigating fish population density responses to habitat fragmentation

Oikos, Volume 2026, Issue 11, November 2026.
Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...

Non‐Native Species Alter Functional Diversity Worldwide: A Systematic Review of Competition, Predation and Habitat‐Mediated Effects in Freshwater Ecosystems

Freshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT The introduction of non‐native species is one of the main threats to biodiversity and ecosystem functioning in freshwater environments, affecting the functional diversity of native communities. Functional diversity, based on phenological, physiological and morphological traits, is a crucial tool for understanding community structure and ...

Guts and Glory: Unraveling the Diet of Eurasian Otter (Lutra lutra) Populations Using DNA Metabarcoding of Gut Contents

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
DNA metabarcoding of gut contents is used to analyze otter diet in two regions of Northern Germany (Schleswig‐Holstein and Lower Saxony). Otters are generalist predators and feed on fish, amphibians, and birds. ABSTRACT The Eurasian otter (Lutra lutra) is a semiaquatic, freshwater top predator of conservation concern due to its significant global ...
