Data from: Concordance in evolutionary history of threatened plant and insect populations warrant unified conservation management approaches

Melinda L. Moir, David J. Coates, W. Jason Kennington, Sarah Barrett, Gary S. Taylor & W. Jason Kensington
Threatened organisms may act as host to a suite of dependent organisms, which are potentially cothreatened, yet management is rarely coordinated between host and dependent species. Here, we test the congruency of patterns of genetic structure between two critically endangered interacting taxa; the feather-leaf banksia (Banksia brownii R.Br.), and its host-specific herbivorous plant-louse Trioza barrettae Taylor & Moir, to establish whether conservation actions should be implemented jointly for both species. We also examine the role...

Data from: Temporal patterns in the abundance of a critically endangered marsupial relates to disturbance by roads and agriculture

Georgina J. Yeatman, Adrian F. Wayne, Harriet R. Mills & Jane Prince
The aim of this study was to investigate how landscape disturbance associated with roads, agriculture and forestry influenced temporal patterns in woylie (Bettongia penicillata) abundance before, during and after periods of rapid population change. Data were collected from an area of approximately 140,000 ha of forest within the Upper Warren region in south-western Australia. Woylie abundance was measured using cage trapping at 22 grid and five transect locations with varying degrees of landscape disturbance between...

Data from: Does population distribution matter? Influence of a patchy versus continuous distribution on genetic patterns in a wind-pollinated shrub

Tanya M. Llorens, Sarah-Louise Tapper, David J. Coates, Shelley McArthur, Margaret Hankinson & Margaret Byrne
Aim: Uniform spatial population distributions are predicted to result in lower among-population genetic differentiation and higher within-population genetic diversity than naturally patchy distributions, but there have been surprisingly few attempts to isolate this effect from confounding factors. We studied the widespread wind-pollinated shrub Allocasuarina humilis that is common in a geologically-stable landscape characterised by long-term population persistence to test the influence of semi-continuous versus patchy population distributions on genetic patterns. We also investigated whether A....

Data from: Contrasting influences of geographic range and distribution of populations on patterns of genetic diversity in two sympatric Pilbara Acacias

Esther Levy, Margaret Byrne, David J. Coates, Bronwyn M. Macdonald, Shelley McArthur & Stephen Van Leeuwen
The influence of geographic range on species persistence has long been of interest and there is a need for a better understanding of the genetic consequences for species with restricted distributions, particularly with the increasing rate of global species extinctions. However, the genetic effects of restricted range are often confounded by the impacts of population distribution. We compared chloroplast and nuclear genetic diversity and differentiation in two acacias, the restricted, patchily distributed Acacia atkinsiana and...

Data from: A novel stereo-video method to investigate fish-habitat relationships

Danielle L. Collins, Tim J. Langlois, Todd Bond, Thomas H. Holmes, Euan S. Harvey, Rebecca Fisher & Dianne L. McLean
Habitat complexity is known to influence the structure of fish assemblages. A number of techniques have previously been used to measure complexity, including quantitative in situ methods, which can be time-consuming and labour-intensive, and more rapid semi-quantitative visual scoring methods. This study investigated the utility of a novel method for estimating complexity, whereby habitat height was measured using stereo-photogrammetry from diver-operated stereo-video, traditionally used to sample fish assemblages. This ‘stereo-height’ method was compared to established...
