Freezing and chemical preservatives alter the stable isotope values of carbon and nitrogen of the Asiatic clam (Corbicula fluminea) [PDF]

, 2011
We tested the impacts of most common sample preservation methods used for aquatic sample materials on the stable isotope ratios of carbon and nitrogen in clams, a typical baseline indicator organism for many aquatic food web studies utilising stable ...

Landscape‐Mediated Effects of Climate Change on Metacommunities Inhabiting Mediterranean Seagrass

Journal of Biogeography, Volume 52, Issue 12, December 2025.
ABSTRACT Aim Climate change affects dramatically biogenic habitats by altering the geographic distribution of the foundational species and the structure of landscapes they form. As a consequence, the associated biotic communities could experience habitat loss and fragmentation.

The changes in the profundal benthos during the extremely low water level in the deep lake Arakhley (Siberia) [PDF]

BIO Web of Conferences
Data on the impact of long-term water level fluctuations on benthic invertebrate communities of the deep lakes in Siberia are scarce due to the rarity of such events and the short history of observations. The studies of the dynamics of zoobenthos and the

Habitat Differences in Resource Density and Distribution Affect Ecology and Life History of a Landscape‐Modifying Fish

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Resource heterogeneity is a widespread phenomenon, as resources are rarely spaced evenly across a landscape. Variation in resource density and distribution can have a myriad of behavioural, ecological, and evolutionary consequences for populations, yet clarifying these effects is still challenging.

Bottom-pelagic links of hydrobionts in the Kara Sea according to data on δ15N and δ13C and feeding of fish

Известия ТИНРО
To compare trophic properties in pelagic and benthic communities of the Kara Sea, isotopic composition of carbon and nitrogen (δ13C and δ15N) was examined in tissues of zooplankton, zoobenthos, and fish.

StrataSeq: A Workflow for Rapid Development of Molecular Databases for Hard‐To‐Identify Species

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Biodiversity loss calls for better monitoring of small, species‐rich taxa, such as soil invertebrates, but traditional methods are limited due to complex morphology and lack of expertise. DNA‐based approaches offer a solution, but their effectiveness depends on incomplete molecular reference databases.

First occurrence of the Ponto-Caspian amphipod Echinogammarus trichiatus (Martynov, 1932) (Crustacea: Gammaridae) in Belgium [PDF]

, 2012
The Ponto-Caspian amphipod species Echinogammarus trichiatus (Martynov, 1932) was found in Belgium for the first time in June 2009 at two different locations in an artificial lake bordered by two large canals.

Effects of Semi‐Natural Habitats on Bird Occupancy in Different Intensity Agriculture: A Multi‐Species Approach

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Agriculture is a primary factor underlying worldwide declines in biodiversity. Incorporating semi‐natural habitat features within agricultural landscapes is considered an effective strategy for mitigating the biodiversity loss associated with agricultural intensification.

Feeding Mystus gulio Fry With Different Dietary Inclusion of Coccomyxa Sp.: Changes in Nutritional Profile, Pigments and Digestive Enzyme Activities

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT The aim of this study was to investigate the effects of Coccomyxa sp. on the survival, nutritional profile, pigments and digestive enzyme activities of Mystus gulio. A 75‐day feeding trial was performed during which the fish fry were fed with microalgae as a partial replacement for other nutritional components.

Status and historical changes in the fish community in Erhai Lake [PDF]

, 2013
Erhai Lake is the second largest freshwater lake on the Yunnan Plateau, Southwest China. In recent decades, a number of exotic fish species have been introduced into the lake and the fish community has changed considerably. We evaluated the status of the
