Comparative analysis of Diptera faunas of hypoarctic of Taimyr Peninsula and high mountains of Altai [PDF]

Кавказский энтомологический бюллетень, 2012
The fauna of Diptera in the hypoarctic zone of Taimyr Peninsula and high mountains of Altai was studied and compared. It was established that in both faunas Brachycera Cyclorrhapha are dominant at all taxonomic ranks (family, genus, species ...

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.

The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

Journal of Applied Entomology, Volume 149, Issue 10, Page 1502-1512, December 2025.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.

Determinants of mating success in a lek‐mating species

Agricultural and Forest Entomology, Volume 27, Issue 4, Page 643-652, November 2025.
Abstract Leks are male‐biased aggregations formed for mating, where sperm is the only resource acquired by visiting females. One of the many advantages of leks is the possibility to efficiently assess the quality of potential mates by comparing aggregated individuals of the same sex with one another. When direct mate choice occurs in a lekking species,

24 million years of pollination interaction between European linden flowers and bumble bees

New Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.
