When log‐dwellers meet loggers: impacts of forest fragmentation on two endemic log‐dwelling beetles in southeastern Australia
Analysis of patch and species characteristics revealed that genetic and demographic structure may be influenced by log degradation class for both species, and number of potential dispersal barriers, distance from continuous forest and desiccation intolerance/moisture preference for Ap.
Polymorphic population genetic markers for the Australian wood cockroach Panesthia australis
Primers for five polymorphic nuclear DNA markers and one mitochondrial DNA gene (COI) were developed for the Australian wood cockroach Panesthia australis using a range of techniques and will be useful for population biology and for the measurement of the effects of habitat fragmentation on this ecologically important forest-dependent species.
Anonymous single‐copy nuclear DNA (scnDNA) markers for two endemic log‐dwelling beetles: Apasis puncticeps and Adelium calosomoides (Tenebrionidae: Lagriinae: Adeliini)
Three approaches — microsatellite library screening, consensus primer PCR (polymerase chain reaction) and sequencing with arbitrary primer pairs (SWAPP) — were used to develop single-copy nuclear DNA (scnDNA) markers for log-dwelling beetles Apasis puncticeps and Adelium calosomoides, but despite exhaustive optimization only five polymorphic markers were obtained.
Habitat fragmentation in forests affects relatedness and spatial genetic structure of a native rodent, Rattus lutreolus
The results suggest that removal of mature forest creates barriers for swamp rat dispersal, and roads may have long-term impacts, while harvesting of native forests is likely to create only short-term dispersal barriers at the local scale, depending on the rate of regeneration.
How far is too far for saproxylicbeetles
Saproxylic beetles drive carbon and nutrient recycling in forestecosystems. Their dependence on dead wood makes them vulnerable to reductions in wood through harvesting and removal for fuel wood.
Physiology Complements Population Structure of Two Endemic Log-Dwelling Beetles
This study studied whether the different habitat requirements of two species of tenebrionid beetles in temperate eucalypt forest could explain their patterns of dispersal and gene flow by applying flow-through respirometry to analysis of their physiological responses to different, ecologically relevant temperatures.
