Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

Functional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Note technique : Entre expérimentations scientifiques et veille écologique: comment évaluer des mesures d’atténuations proposées par une étude d’impacts? Le cas de canalisations enterrées dans la plaine de Crau [PDF]

Sciences, Eaux & Territoires, 2011
L’évaluation de la pertinence des mesures d’atténuations proposées par une étude d’impacts lors d’un projet d’aménagement s’effectue par la mise en place de veilles écologiques. Néanmoins, ce type de suivis est rare puisqu’aucune législation ne l’impose.

L'homme et l'animal dans le bassin du lac Tchad [PDF]

, 1999
Le glossaire (encore incomplet) du vocabulaire des Mofu de Douvangar recense près de 140 mots désignant des insectes et autres anthropodes. Ce vocabulaire est analysé d'un point de vue exclusivement entomologique.

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

Journal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting
