Ecology and Evolution, Volume 16, Issue 1, January 2026.The study demonstrates that sufficient B supply is crucial for successful rapeseed flower growth and fertility as well as for attracting pollinating insects, thus securing yield in a pollinator‐dependent crop. It is illustrated that climate change can pose a threat to crop yield via both direct effects, that is, an impaired nutrient uptake, and ...

Ecology and Evolution, Volume 16, Issue 1, January 2026.The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).

Polymorphism in Stelopolybia Areata (Hymenoptera, Vespidae) [PDF]
Psyche: A Journal of Entomology, 1974 Polymorphism in the social Hymenoptera has been defined as the occurrence within a single colony of two or more distinct morphological forms, or castes, belonging to the same sex (Wilson 953). Wilson (953) has pointed out that polymorphism arises out of the occurrence of allometry (differential rates of growth o.f two parts of the body) over a ...

Molecular Ecology, Volume 35, Issue 1, January 2026.ABSTRACT Biological invasions are major drivers of recent biodiversity changes, yet the genetic structure and ecological mechanisms underlying invasion dynamics remain poorly resolved in invasive social insects. In South Africa, the European wasp Vespula germanica (Hymenoptera: Vespidae), introduced in the 1970s, has spread remarkably more slowly than ...

Sociobiology, 2022 Ants prey on social wasps affecting the evolution of nest architecture, defense behaviors, and selection of nesting sites of these insects. The importance of social wasps in natural and agricultural ecosystems, especially in biological control, justifies studies on predation of these insects by ants.

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...
