Data from: Empirical tests of harvest-induced body-size evolution along a geographic gradient in Australian macropods

Thomas A. A. Prowse, Rachel A. Correll, Christopher N. Johnson, Gavin J. Prideaux & Barry W. Brook
1. Life-history theory predicts the progressive dwarfing of animal populations that are subjected to chronic mortality stress but the evolutionary impact of harvesting terrestrial herbivores has seldom been tested. In Australia, marsupials of the genus Macropus (kangaroos and wallabies) are subjected to size-selective commercial harvesting. Mathematical modelling suggests that harvest quotas (ca. 10–20 % of population estimates annually) could be driving body-size evolution in these species. 2. We tested this hypothesis for three harvested macropod...

Data from: Living near the edge: being close to mature forest increases the rate of succession in beetle communities

In increasingly fragmented landscapes, it is important to understand how mature forest affects adjacent secondary forest (forest influence). Forest influence on ecological succession of beetle communities is largely unknown. We investigated succession and forest influence using 235 m long transects across boundaries between mature and secondary forest at 15 sites, sampling a chronosequence of three forest age classes (5-10, 23-29 and 42-46 years since clearcutting) in tall eucalypt forest in Tasmania. Our results showed that...

Data from: Genome-wide scans detect adaptation to aridity in a widespread forest tree species.

Dorothy A. Steane, Brad M. Potts, Elizabeth McLean, Suzanne M. Prober, William D. Stock, René E. Vaillancourt & Margaret Byrne
Patterns of adaptive variation within plant species are best studied through common garden experiments, but these are costly and time-consuming, especially for trees that have long generation times. We explored whether genome-wide scanning technology combined with outlier marker detection could be used to detect adaptation to climate and provide an alternative to common garden experiments. As a case study, we sampled nine provenances of the widespread forest tree species, Eucalyptus tricarpa, across an aridity gradient...

Data from: Molecular genetics to inform spatial management in benthic invertebrate fisheries: a case study using the Australian greenlip abalone

Karen J. Miller, Craig N. Mundy & Stephen Mayfield
Hierarchical sampling and subsequent microsatellite genotyping of >2,300 Haliotis laevigata (greenlip abalone) from 19 locations distributed across five biogeographic regions has substantially advanced our knowledge of population structure and connectivity in this commercially-important species. The study has found key differences in stock structure of H. laevigata compared with the sympatric and con-generic Haliotis rubra (blacklip abalone) and yielded valuable insights into the management of fisheries targeting species characterised by spatial structure at small scales (i.e....

Data from: Global biodiversity assessment and hyper-cryptic species complexes: more than one species of elephant in the room?

Mark Adams, Tarmo A. Raadik, Christopher P. Burridge & Arthur Georges
Several recent estimates of global biodiversity have concluded that the total number of species on Earth lies near the lower end of the wide range touted in previous decades. However, none of these recent estimates formally explore the real ‘elephant in the room’, namely, what proportion of species are taxonomically invisible to conventional assessments, and thus, as undiagnosed cryptic species, remain uncountable until revealed by multi-gene molecular assessments. Here we explore the significance and extent...
