Abstract:
Population densities, using distance sampling, and habitat associations of the range-restricted Rock Firefinch Lagonosticta sanguinodorsalis were investigated between late May and early July 2002 in a protected site at Amurum on the Jos Plateau, Nigeria, and in unprotected surrounding habitats. Rock Firefinches were strongly associated with inselbergs and rocky outcrops and avoided scrub and abandoned farmland. Density was not significantly higher on the Amurum protected site (0.79 birds/ha; 95% CL 0.51–1.21) than on the unprotected areas (0.55 birds/ha; 95% CL 0.37–0.82). Rock Firefinches wer

Abstract:
Studies of niche overlap within communities of lizards have shown that separation may be along the three major dimensions of space, time and food. Space is usually the most important dimension where a range of habitats are involved; there is less information on the importance of microhabitat separation within a single habitat type. This study investigated microhabitat relationships of small diurnal lizard species occupying granitic rock habitat in Zimbabwe. There was statistically significant niche separation among all species in both the type of rock occupied (size, shape, number of cracks, c

In the Increase phase, it showed no strong habitat preferences, perhaps because the abundance of food (seeds) overrode preferences for more stable habitat values.

Abstract:
The genus Cyrtodactylus is the most diverse and widely distributed group of geckos in the world. Throughout their extensive range, species exploit a diverse range of habitats and are able to partition niches locally. Recent work has shown that Cyrtodactylus geckos in Queensland, Australia, have radiated in situ after colonisation by an arboreal Papuan ancestor and have undergone a habitat switch to rock dwelling during their evolutionary history. Using mitochondrial data we conducted a phylogeographic and molecular dating analysis to investigate the historical biogeography of Cyrtodactylus spe

Little is known about how vertical rock habitats are selected by organisms in forest ecosystems. Multiple lungless salamanders use rock outcrops in the Appalachian Mountains of eastern North America, with Green Salamanders (Aneides aeneus (Cope and Packard, 1881)) showing the strongest associations as an outcrop specialist. Although previous work has identified environmental correlates of rock face and arboreal habitat use in this species, it remains to be known if and how Green Salamanders select crevice refugia as a function of both outcrop morphology and the context of outcrops within the s

Abstract:
The Precambrian Shield supports a diversity of cryptogams where environmental conditions predict their distribution. Moisture and light are thought to affect secondary metabolite production in lichens, leading to a hypothesis of chemical communities that may be independent of species assemblages. Hypotheses were that habitats will be characterized by lichen secondary metabolites and that lichen and bryophyte species composition will also distinguish among habitats. Lichens and bryophytes were sampled from six quadrats from each of two sites within each of three habitats (rock faces, rock outcr

Settlement of cod did not differ between habitat types, but postsettlement survival and subsequent juvenile densities were higher in more structurally complex habitats.

Several studies have tried to increase the surface complexity on coastal defence structures through eco-engineering habitat enhancements that mimic nature. However, few of these studies have been c

AbstractThe lichen flora and habitats in the Syowa region of continental Antarctica were surveyed. The distribution patterns of lichens appear to reflect habitat salinity, derived from wind-blown sea spray. Some halotolerant species are established in saline habitats where snow dunes are well developed. Snow and ice ameliorate the salinity of the habitat and provide a major source of moisture for lichens. Wind-borne drift snow carried by katabatic winds or occasional snow showers also provide the source of moisture to lichens growing on dry rock habitats in the Syowa region.
