Although corridors are frequently regarded as a way to mitigate the negative effects of habitat fragmentation, concerns persist that corridors may facilitate the spread of invasive species to the detriment of native species.
The invasive fire ant, Solenopsis invicta, has two social forms. The polygyne form has limited dispersal abilities relative to the monogyne form. Our previous work in a large‐scale...
For a half century, habitat configuration – the arrangement of habitat patches within a landscape – has been central to theories of landscape ecology, population dynamics, and community assembly, in addition to conservation strategies. A recent hypothesis advanced by Fahrig (2013) would, if supported, greatly diminish the relevance of habitat configuration as a predictor of diversity. The Habitat...
Activity in the mesocorticolimbic dopamine system is linked to responses to novelty, reward, and drug-seeking behaviours. Glutamate signaling, through kainate receptors, has been shown to modulate dopamine release in this pathway. In the present study, a low, overtly non-convulsive dose of the kainate receptor agonist, domoic acid (DOM), was administered to rat pups over PND 8–14. As juveniles and...
