Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

open access: yesNew Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

open access: yesAustral Ecology, Volume 51, Issue 2, February 2026.
Urbanisation is a powerful environmental force, negatively impacting the few organisms that persist in urban areas. Here, we investigated the relationship between urbanisation intensity and Fluctuating asymmetry (FA) in birds. Our results suggest that urbanisation (even at lower intensities) may impose stronger genetic and/or environmental stress on ...

Abstract Despite calls for wider inclusion of diverse actors in conservation management, researchers tend to lump actors together into one group, potentially overlooking heterogeneity within the groups themselves—in turn, hampering inclusiveness. The risk of stereotyping social actors and oversimplifying their differentiated preferences for Nature's ...
