Preliminary investigations of the species composition of the aculeate hymenopteran community in Chornobyl Radiation and Ecological Biosphere Reserve (Hymenoptera, Aculeata) [PDF]

Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”
The Chornobyl Radiation and Ecological Biosphere Reserve is a unique location, which is an area of posttechnogenic habitat restoration, including the Chornobyl Exclusion Zone, where comprehensive surveys of insect diversity have not yet been conducted ...

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Cecidonius pampeanus, gen. et sp. n.: an overlooked and rare, new gall-inducing micromoth associated with Schinus in southern Brazil (Lepidoptera, Cecidosidae)

ZooKeys, 2017
Galls induced by the larval stage of cecidosids (Lepidoptera: Cecidosidae) are complex, multi-trophic systems, still poorly studied. They may be associated with other insect feeding guilds, including inquilines, kleptoparasites, cecidophages, parasitoids,

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

Ecological Entomology, Volume 51, Issue 2, Page 284-294, April 2026.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...

Overlooked gall-inducing moths revisited, with the description of Andescecidium parrai gen. et sp. n. and Oliera saizi sp. n. from Chile (Lepidoptera, Cecidosidae)

ZooKeys, 2018
There are still many gall systems associated with larvae of Lepidoptera in which the true gall-inducers have not been identified to species. Reports on misidentification of gall inducers have been recurrent for these galls, particularly in complex gall ...

Contemporary Foraging of the Hawaiian Monk Seal as a Retrospective Lens for Commercial Fishing and Its Relevance to Ecosystem‐Based Fishery Management

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT This retrospective analysis explores how historical fishing activity (1948–2009) at French Frigate Shoals (FFS) can be examined in relation to the foraging ecology of Hawaiian monk seals. We bring together fisheries catch records, monk seal demographic information, and ecological studies on prey, competitors, and predators to evaluate ...

Kleptoparasitism and the distribution of unequal competitors [PDF]

Behavioral Ecology, 2002
Kleptoparasitism is an important means by which many animals obtain limited resources. The success of kleptoparasitism may be influenced by a number of factors, including competitive differences among individuals and the spatial distribution of prey and hosts.

The presence of kleptoparasitic fledglings is associated with a reduced breeding success in the host family in the barn owl

Journal of Avian Biology, 2018
Fledgling birds sometimes abandon their own nest and move to neighboring nests where they are fed by host parents. This behaviour, referred to as ‘nest‐switching’, is well known in precocial birds that are mobile soon after hatching and can easily reach ...

The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

Mammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

Kleptoparasitism in seabirds—A potential pathway for global avian influenza virus spread

Conservation Letters
Wild birds have experienced unprecedented, near‐global mass mortalities since 2021, driven by outbreaks of high‐pathogenicity avian influenza virus (HPAIV) H5N1 lineage 2.3.4.4b.
