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 ...

Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.

Experimental droughts in mesocosms reveal a gradient of tolerance in Alpine stream macroinvertebrates

Limnology and Oceanography, Volume 70, Issue S2, Page S352-S363, December 2025.
Abstract Prolonged droughts, driven by climate change and human pressures on water resources, are increasing in frequency and intensity, particularly impacting Alpine rivers. Benthic macroinvertebrates are one of the most important structural and functional components of Alpine lotic ecosystems.

Long Story of Long Antennae: Mesozoic Origins of the Subfamily Macrocerinae (Diptera: Keroplatidae)

Acta Geologica Sinica - English Edition, Volume 99, Issue 5, Page 1225-1248, October 2025.
Abstract The early evolutionary history of the Macrocerinae subfamily (Diptera: Keroplatidae) is poorly understood. However, new material from the Cretaceous, particularly in amber, provides a better understanding of this subject. We reassign the oldest known species of Macrocerinae, Hegalari minor Blagoderov & Arillo, 2002, from the amber of Álava ...

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.
