Genetic spatial autocorrelation can readily detect sex‐biased dispersal
TLDR
Congruence was found between simulation predictions and empirical data from the agile antechinus, a species that exhibits male‐biased dispersal, confirming the power of individual‐based genetic analysis to provide insights into asymmetries in male and female dispersal.
Starting points for small mammal population recovery after wildfire: recolonisation or residual populations?
TLDR
The findings suggest these species do not depend on recolonisation for recovery, and that the bush rat will follow a nucleated recovery, expanding from topographic refugia, rather than being limited by demographic rates and resource availability.
Oceanic variability and coastal topography shape genetic structure in a long-dispersing sea urchin.
TLDR
It is suggested that the optimal scale for fisheries management and reserve design should vary among localities in relation to regional oceanographic variability and coastal geography, and that ocean current circulation may interact with the genetic consequences of large variance in individual reproductive success to generate patterns of fine-scale patchy genetic structure.
Newly discovered landscape traps produce regime shifts in wet forests
TLDR
The concept of landscape traps is described, whereby entire landscapes are shifted into, and then maintained in, a highly compromised structural and functional state as the result of multiple temporal and spatial feedbacks between human and natural disturbance regimes.
The effects of habitat fragmentation via forestry plantation establishment on spatial genotypic structure in the small marsupial carnivore, Antechinus agilis
TLDR
The impacts of habitat fragmentation resulting from establishment of an exotic pine plantation on dispersal of the marsupial carnivore, Antechinus agilis, is studied to provide evidence for significantly increased gene flow through habitat corridors relative to that across the matrix and for significantly lower gene flow between ‘mainland’ unfragmented habitat and habitat patchesrelative to that within either habitat type.
Sex and sociality in a disconnected world: A review of the impacts of habitat fragmentation on animal social interactions
TLDR
This work focuses on the impacts of habitat fragmentation that are expected to, or have been observed to, affect social strategies, and these social impacts or responses may contribute to population viability and broad-scale patterns of distribution and abundance in fragmented landscapes.
