A new species of the genus Geranomyia Haliday, 1833 (Diptera: Limoniidae) from Transcaucasia [PDF]

Кавказский энтомологический бюллетень, 2015
The description of a new species, Geranomyia eugeniana Lantsov, sp. n. from Transcaucasia (Georgia; Russia: Khosta) is given. The new species is compared with the very similar Western Palaearctic species Geranomyia caloptera from which it differs in the ...

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras

Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.
We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Testing the Optimal Foraging Theory in a Generalist Feeder: The Case of Reintroduced European Pond Turtles and Its Impact on Macroinvertebrates Communities

Ecology and Evolution, Volume 15, Issue 8, August 2025.
In this study we investigated the macroinvertebrate (MI) communities in two newly created, man‐made ponds concurrently with the diet of captive‐bred European pond turtles that were translocated there. We aimed at assessing whether turtles were operating as generalist feeders, and if successive reintroductions of turtles would affect the overall MI ...

Investigating the Effects of Flow Regulation Combining Stream Geomorphology With Macroinvertebrate Ecology: A Case Study in the Orobic Alps (Italy)

Ecohydrology, Volume 18, Issue 5, July‐August 2025.
ABSTRACT Mountain streams exhibit hydrogeomorphological heterogeneity, which is further intensified by the presence of hydraulic infrastructure. Despite extensive research on the influence of hydrological conditions and flow regulation on ecology, there is a notable absence of holistic studies investigating stream dynamics from both geomorphologic and ...

Length–Dry Mass Relationships of Aquatic Insects: Geographic and Taxonomic Variation in a Digital Database

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Aquatic insects are an abundant, yet declining, taxonomically heterogeneous group with special importance in both aquatic and terrestrial ecosystems. Accurate estimations of insect biomass during their aquatic life stages are essential to advance our fundamental knowledge about insects, their roles in ecosystems, and their vulnerability to ...

A Kick in the Headwaters: Evaluating a Macroinvertebrate Sampling Method for Ecological Condition Monitoring in Small Streams

River Research and Applications, Volume 41, Issue 4, Page 808-819, May 2025.
ABSTRACT Small streams dominate river networks and collectively support high biodiversity, but are rarely included in regulatory biomonitoring programmes. Macroinvertebrate communities are effective biomonitors of ecological condition and are routinely collected using 3‐min ‘kick’ samples.

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

Freshwater 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

Stream Invertebrate Responses to Fine Sediment Depend on the Organic and Inorganic Components

Freshwater Biology, Volume 70, Issue 3, March 2025.
ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects ...

Estimating Rapid Diversity Changes During Acute Herbicide Contamination Using Environmental DNA

Environmental DNA, Volume 7, Issue 1, January–February 2025.
This study evaluates the use of environmental DNA metabarcoding to examine rapid changes in aquatic invertebrate communities following exposure to glyphosate‐based herbicide (GBH) in mesocosms under contrasted nutrient levels. We show a shift in community composition induced by GBH, and different impacts on zooplankton and insect family richness.
