Les prairies permanentes occupent environ un tiers de la surface agricole utile et présentent un grand potentiel de diversité biologique. L’élevage a de ce fait un rôle majeur à jouer dans la préservation de la biodiversité sur le territoire français. L’

Allelopathic effect of the Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of germinated seedlings in Allium cepa L. [PDF]
The allelopathic activity of the different type of Cladonia verticillaris lichen extracts and fumarprotocetraric acid on the early growth of A. cepa (IPA 6) germinated seedlings depends on their chemical composition and concentration, respectively.

Germination responses to light of four Neotropical forest tree species along an elevational gradient in the southern Central Andes [PDF]
Seed germination is a key part of plants' life cycle and is mostly affected by the genetic background, the environmental conditions experienced by the mother plant and the seedbed conditions.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Although phenology has long been recognized as a critical feature for the adaptation of organisms to their local environment, until recently, phenological events have seldom been considered in the broader context of trait‐based ecology.

Spatial overlap and temporal synchrony between guilds of insect hosts and parasitoids
This study identified a spatial overlap between insect host guild richness and parasitoid richness. Species richness in parasitoid guilds always increased later in the season than richness of their host guilds. These findings suggest that shifts in climate and land‐use may alter the synchrony of insect trophic layers.
