Dispersal among breeding sites in territorial animals (i.e. breeding dispersal) is driven by numerous selection pressures, including competition and spatiotemporal variation in habitat quality. The scale and trend of dispersal movements over time may signal changing conditions within the population or on the landscape. We examined 2,158 breeding dispersal events from 694 male and 608 female individually-marked Northern Spotted Owls (Strix occidentalis caurina) monitored over 28 years on seven study areas to assess the relative...

Data from: Historical population size change and differentiation of relict populations of the endangered giant kangaroo rat

Mark J. Statham, William T. Bean, Nathan Alexander, Michael F. Westphal & Benjamin N. Sacks
From a conservation management perspective it is important to understand how genetic diversity is partitioned across a species’ range, including (1) identification of evolutionarily distinct units versus those recently isolated through anthropogenic activities and (2) the relative genetic contributions among components of fragmented (meta)populations. To address these questions, we investigated the phylogeography and metapopulation structure among relict populations of the endangered giant kangaroo rat (Dipodomys ingens) in the highly altered San Joaquin Desert Ecosystem. This...
