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

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

AbstractEcologically versatile Anolis schwartzi from St. Eustatius (Lesser Antilles) occurs in various habitats, usually in shaded situations and often in higher densities when associated with rock piles, rock slides, and stone walls. In order to evaluate the mating systems of A. schwartzi in different habitats, we examined populations in rocky and adjacent forested plots in Boven National Park to test the following predictions: (1) Population densities would be higher in habitats with rocks or rock slides than in nearby areas of forest without rocks.

The individuals of many species shift habitats at different stages in their lives. Sometimes, these habitat shifts coincide with an ontogenetic transition. These ontogenetic habitat shifts can allow species to access nutritional resources, avoid conspecific aggression or predation, or secure breeding opportunities when it is advantageous to do so.

We determined preferences of the Pilliga mouse, Pseudomys pilligaensis, for habitat attributes (ground and vegetation cover) through phases of a population irruption, and characterised refuge sites used when environmental conditions were unfavourable. In general, P. pilligaensis preferred areas with substrate dominated by sand and shrubs rather than rock or litter. However, its habitat selection changed with phases of the irruption. In the Increase phase, it showed no strong habitat preferences, perhaps because the abundance of food (seeds) overrode preferences for more stable habitat values.

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

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

Newly settled cod were marked with acrylic dye, allowing repeated visual length estimates of individual fish. Settlement of cod did not differ between habitat types, but postsettlement survival and subsequent juvenile densities were higher in more structurally complex habitats. These differences appear to be due to increased shelter availability and decreased predator

Two species were rock pool specialists that lived on spatially complex rocky shores, while the remainder lived on dynamic, but structurally simple, sandy shores.

Coastlines are drastically altered globally due to urbanisation and climate-related issues. As a response, communities build coastal defence structures to protect people and property. Although these infrastructures fulfil engineering demands of coastal defences, the trade-off to nature includes a decrease in biodiversity able to live on these structures because of the lack of topographic complexity. 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.
