Evaluating range-expansion models for calculating nonnative species' expansion rate
Species range shifts associated with environmental change or biological invasions are increasingly important study areas. However, quantifying range expansion rates may be heavily influenced by methodology and/or sampling bias. We compared expansion rate estimates of Roesel's bush-cricket (Metrioptera roeselii, Hagenbach 1822), a nonnative species currently expanding its range in south-central ...
متن کاملReduced inbreeding depression after species range expansion.
Many species expanded their geographic ranges from core "refugium" populations when the global climate warmed after the Pleistocene. The bottlenecks that occur during such range expansions diminish genetic variation in marginal populations, rendering them less responsive to selection. Here, we show that range expansion also strongly depletes inbreeding depression. We compared inbreeding depress...
متن کاملTitle: Species Range Expansion Constrains the Ecological Niches of Running Header: Range Expansion and Changes in Species Interactions
21 Aim Changes in community composition resulting from environmental changes modify biotic 22 interactions and affect the distribution and density of local populations. Such changes are currently 23 occurring in nettle-feeding butterflies in Sweden where Araschnia levana has recently expanded 24 its range northward and is now likely to interact with the resident species (Aglais urticae and Agla...
متن کاملTrichoderma Species Associated with Medicinal Plants
Objective: The genus Trichoderma comprises a great number of fungal strains that act as biological control agents, the antagonistic properties of which are based on the activation of multiple mechanisms. Methods: Trichoderma strains exert biocontrol against fungal phytopathogens either indirectly, by competing for nutrients and space, modifying the environmental conditions, or promotin...
