Capturing genetic variation in crop wild relatives: An evolutionary approach
<p>Crop wild relatives (CWRs) offer novel genetic resources for crop improvement. To assist in the urgent need to collect and conserve CWR germplasm, we advance here the concept of an “evolutionary” approach. Central to ...
Questing abundance of adult taiga ticks Ixodes persulcatus and their Borrelia prevalence at the north-western part of their distribution
BackgroundBecause ixodid ticks are vectors of zoonotic pathogens, including Borrelia, information of their abundance, seasonal variation in questing behaviour and pathogen prevalence is important for human health. As ticks ...
Role of breeding and natal movements in lifetime dispersal of a forest-dwelling rodent
The lifetime movements of an individual determine the gene flow and invasion potential of the species. However, sex dependence of dispersal and selective pressures driving dispersal have gained much more attention than ...
Shifts in structural diversity of Amazonian forest edges detected using terrestrial laser scanning
Forest edges are an increasingly common feature of Amazonian landscapes due to human-induced forest frag-mentation. Substantial evidence shows that edge effects cause profound changes in forest biodiversity and productivity. ...
Food quality affects the expression of antimicrobial peptide genes upon simulated parasite attack in the larvae of greater wax moth
Predator-prey interactions are an important evolutionary force affecting the immunity of the prey. Parasitoids and mites pierce the cuticle of their prey, which respond by activating their immune system against predatory ...
Investigating associations between nematode infection and three measures of sociality in Asian elephants
<p>Frequent social interactions, proximity to conspecifics, and group density are main drivers of infections and parasite transmissions. However, recent theoretical and empirical studies suggest that the health benefits ...
