Predictors of resistance to brood parasitism within and among reed warbler populations

In the coevolutionary arms race between avian brood parasites and their hosts, several adaptations have evolved on both sides, the most prominent and important host defense being rejection of the parasitic egg.

Sex‐Biased Interactions Between Spur‐Thighed Tortoises (Testudo graeca) and Hindgut Nematodes

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Tortoise (Testudo graeca) responses to nematode infestation are clearly sex‐biased, where females seem more resilient to nematode infestation than males. These findings emphasizes the need for sex‐directed conservation approaches in tortoises. ABSTRACT The nature of endosymbiont interactions is driven by different ecological and evolutionary processes.

Wild Bee Conservation: Habitat Heterogeneity and Ecological Improvement in Agricultural Land With Open Grassland

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Here, we investigated the effects of different levels of habitat heterogeneity and of ecological improvement of habitat to increase foraging resources on wild bee communities in Austria and Luxembourg. We found that ecological improvement was important in Luxembourg for species richness and abundance but less so in Austria; here, habitat heterogeneity ...

Rainforest conversion to monoculture plantations restructures functional communities of braconid parasitoid wasps

Oikos, Volume 2026, Issue 10, October 2026.
The conversion of rainforests into rubber and oil palm plantations drives biodiversity loss in Southeast Asia. Parasitoid wasps are highly diverse and play an essential role in ecosystems by regulating herbivore populations. Declines in density and diversity of parasitoid wasps, after land‐use change is well‐documented, but potential functional losses ...

Wood duck nest survival and duckling recruitment is minimally affected by interspecific brood parasitism from hooded mergansers and black-bellied whistling-ducks.

PLoS ONE
In the southeastern United States, wood ducks (Aix sponsa) have historically experienced interspecific brood parasitism (IBP) primarily from hooded mergansers (Lophodytes cucullatus), but the recent northward expansion of black-bellied whistling-ducks ...

Analysis of the Black-capped Vireo and White-eyed Vireo Nest Predator assemblages [PDF]

, 2010
Predation is the leading cause of nest failure in songbirds. My study identified nest predators of black-capped vireos and white-eyed vireos, quantified the activity of potential predator species, examined the relationships between vegetation and nest ...

Co‐phylogeny and biogeography of the myrmecophilous beetle Paussus favieri (Carabidae, Paussinae) and its host ant Pheidole pallidula (Hymenoptera, Myrmicinae)

Insect Science, Volume 33, Issue 5, Page 2210-2226, October 2026.
Strict patterns of co‐divergence have rarely been documented other than among organisms and their symbionts. In this paper, using a molecular approach, we inferr the population‐level phylogenies of a Mediterranean ant species Pheidole pallidula and its nest parasite, the obligate myrmecophilous beetle Paussus favieri. We then investigate the role of co‐

Host use by Philornis sp. in a passerine community in central Argentina Uso de hospedadores por Philornis sp. en una comunidad de aves paseriformes de la parte central de Argentina

Revista Mexicana de Biodiversidad, 2012
We studied host use by parasitic botflies (Philornis sp.) in a passerine community in central Argentina and analyzed characteristics of nests and hosts associated with botfly parasitism.

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

Ecological Entomology, Volume 51, Issue 5, Page 926-943, October 2026.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Black-capped Vireos and White-eyed Vireos: How two birds adapt to challenges of living in Central Texas [PDF]

, 2016
Thesis (Master's)--University of Washington, 2016-12Black-capped vireos (Vireo atricapilla) and white-eyed vireos (Vireo griseus) are closely related songbirds, which occupy the same landscape in Central Texas.
