The incidence of bacterial endosymbionts in terrestrial arthropods. [PDF]
, 2015 Intracellular endosymbiotic bacteria are found in many terrestrial arthropods and have a profound influence on host biology. A basic question about these symbionts is why they infect the hosts that they do, but estimating symbiont incidence (the ...

Oikos, Volume 2025, Issue 5, May 2025.Symbionts are key elements of ecosystems, by playing important roles in shaping the biology and ecology of their hosts. However, the factors determining symbiont loads across host species are still unclear. Nowadays, we know that the intensity and prevalence of feather mites, the most diverse group of avian ectosymbionts, differ strongly between ...

Gonads and gametogenesis in astigmatic mites (Acariformes: Astigmata)
Arthropod Structure & Development, 2014 Astigmatans are a large group of mites living in nearly every environment and exhibiting very diverse reproductive strategies. In spite of an uniform anatomical organization of their reproductive systems, gametogenesis in each sex is highly variable, leading to gamete formation showing many peculiar features and emphasizing the distinct position of ...

Ecology and Evolution, Volume 15, Issue 3, March 2025.We investigated the radiation and trait diversity of soil oribatid mites from two mountain ranges (the Alps and Changbai Mountain). We found that phylogenetically older oribatid mites of mountain ranges have broader trophic variation, larger geographical range sizes, and more often reproduce via parthenogenesis.

Feeding Ecology of the Critically Endangered Gobio insuyanus (Gobionidae)
Ecology and Evolution, Volume 15, Issue 3, March 2025.This study investigates the diet of the critically endangered Gobio insuyanus in the Insuyu spring–stream system, revealing omnivorous feeding habits with a preference for detritus, Gammarids, and Diptera larvae. Ontogenetic dietary shifts were observed, with mature individuals specializing in larger prey, while habitat and seasonal variations ...

Medical and Veterinary Entomology, Volume 39, Issue 1, Page 14-21, March 2025.A servosphere was used to record the speed, directionality and phototaxis of individual post‐feeding larvae of two species of blow fly (Diptera: Calliphoridae) on a smooth plastic surface over time. The servosphere rotates to compensate for the movement of an insect placed at its apex, thereby facilitating its unimpeded locomotion in any direction and ...

Ecological Applications, Volume 35, Issue 1, January 2025.Abstract Subsidy–stress gradients offer a useful framework for understanding ecological responses to perturbation and may help inform ecological metrics in highly modified systems. Historic, region‐wide shifts from bottomland hardwood forest to row crop agriculture can cause positively skewed impact gradients in alluvial plain ecoregions, resulting in ...
