The quality of the surrounding landscape matrix often determines biodiversity pattern remaining natural habitat fragments. Dispersal organisms depends mostly on species traits related to mobility and contrast between fragment matrix. Therefore, variation in composition among fragments, i.e. beta-diversity, can also be affected by quality. In our study, we focused structurally complex forest ste...

Aim The aim was to characterize fire regimes and estimate regime parameters (area burnt, size, intensity, season, patchiness pyrodiversity) at broad spatial scales using remotely sensed individual-fire data. Location Western part of the Palaearctic realm (i.e., Europe, North Africa Near East). Time period 2001–2021. Methods Initially, I divided study area into eight large ecoregions based on th...

Les transitions archeologiques se caracterisent notamment par d’importants changements demographiques et societaux, qui peuvent avoir des repercussions a l’echelle du genome individus. Ainsi, la transition Neolithique l’âge Bronze s’est accompagnee de contributions genomiques massives d’eleveurs originaires steppes pontico-caspiennes aux populations locales, ces dernieres resultant d’interactio...

Plant species α-diversity is closely correlated with ecosystem structures and functions. However, whether climate change human activities will reduce plant remains controversial. In this study, potential (i.e., richness: SRp, Shannonp, Simpsonp Pieloup) actual SRa, Shannona, Simpsona Pieloua) during 2000–2020 were quantified based on random forests in grasslands the Tibetan Plateau. Overall, ha...

Habitat fragmentation threatens terrestrial arthropod biodiversity, and thereby also leads to alterations of ecosystem functioning stability. Predation on insects seeds by arthropods are two very important ecological functions because their community-structuring effects. We addressed the effect fragment connectivity, size, edge insect seed predation arthropods. studied 60 natural fragments gras...

The soil–vegetation relationships are reciprocal and fundamental for terrestrial ecosystem integrity. However, the long-term degradation of vegetation cover alters edaphic conditions, which can lead to habitats, obstructs proper functioning. This study aimed assess effects perennial steppe due overgrazing (i.e., continuous free grazing) on physicochemical characteristics soil fertility in range...

Abstract Background Understanding the response of plant community to increasing nitrogen (N) and phosphorus (P) inputs is helpful for managing protecting grassland ecosystems in semiarid areas. However, information about different types steppe responses N P availability grasslands limited. In 2017–2018, two field experiments were conducted with six levels (from 5 30 g m ?2 yr ?1 ) 2.5 15 additi...
