Breeding success is a critical component of population stability and is often influenced by the habitats used during the breeding season. Current hypotheses suggest that sharp-tailed grouse ( Tympanuchus phasianellus (L., 1758)) select nest and brood-rearing habitats that provide both lateral and overhead cover to avoid detection by predators. We examined the selection of nesting and brood-rearing habitats of sharp-tailed grouse at three spatial scales (landscape, patch, and site) in northeastern British Columbia using standard and conditional logistic regression models and an information–theoretic approach. At the patch and site scales, our results validate our predictions, as nesting females selected shrub–steppe habitats, greater shrub and grass cover, taller vegetation, and greater residual vegetation compared with random sites. Brood-rearing females selected for agricultural habitats during the early brood-rearing period (0–14 days), but did not show selection of any habitat type or site attribute during the late brood-rearing period (15–49 days). We suggest that the selection of shrub-dominated habitats by nesting females supports the hypothesis that females select sites and habitats that maximize concealment. We further suggest that selection of shrub-dominated habitat is occurring in response to changes in habitat conditions and availability, as natural grassland communities have diminished across the landscape.

We examined the characteristics of microhabitats selected by Western green lizards, Lacerta bilineata. Model selection was carried out with the Information-theoretic approach that focuses on the estimation of effect size and measures of its precision. Our results show that the Western green lizard selects positively sites with good shrub cover, necessary as shelter, while it avoids areas with bare soil where there are no refuges. Additionally, lizards showed a positive selection of rocks (located exclusively in artificial riverbanks) that represent a suitable habitat for thermoregulation and sheltering. The results of our work, and particularly the negative effects of bare soil and the positive effects of shrub cover, confirm the need to restore the network of hedgerows and other linear elements in cultivated landscapes in order to create suitable areas for L. bilineata.
