“…Indeed, spatial variation in the composition of plant and animal communities has been shown for a variety of taxa, at various scales and across various regions (Gentry 1988;McCoy 1990;Davidson 1993;Jorgensen & Demarais 1999;Orrock et al 2000;Mortelliti & Boitani 2007). One of the most important reasons for spatial variation in community composition is variation in the environmental conditions.…”

We investigated host and flea species composition across different habitats during dry and rainy seasons in the Western Usambara Mountains in Tanzania. During both seasons, similarity in flea species composition increased with an increase in the similarity in host species composition. Nevertheless, between-season within-habitat as well as within-season between-habitat similarity in host species composition was higher than similarity in flea species composition. Ordination of habitats according to their host and flea species composition demonstrated that the pattern of between-habitat similarity in both host and flea species composition varied seasonally. Despite the relatively rich mammal and flea fauna of the study region, the major contribution to variation in species composition between seasons and among habitats was due to a few species only. Flea assemblages on Lophuromys kilonzoi Verheyen et al., 2007 and Praomys delectorum Thomas, 1910 in different habitats were equally similar in either season. In contrast, flea assemblages on Mastomys natalensis (Smith, 1834) occurring in different habitats were more similar in the dry than in the rainy season, whereas the opposite was the case for fleas on Grammomys sp. In different hosts, the main differences in species composition of flea assemblages between seasons as well as among habitats were due to different flea species. Although our results support the earlier idea that parasite species composition is determined by both host species composition and habitat properties, the former appears to explain variance in flea species composition between localities in the tropics better than between localities in temperate and arid zones.

“…An additional problem involves defining the scales of analysis that allow species which use habitat patches (specialists) to be distinguished from those which do not show a habitat selection pattern on the same scale (generalists) (Coppeto et al, 2006;Morris, 1996). In the particular case of desert rodents, several attempts to link macro and microhabitat selection patterns have been made, although there is disagreement whether the principal factor directing habitat selection is the macrohabitat (see for instance Morris, 1987;Jorgensen and Demarais, 1999;Coppeto et al, 2006) or the microhabitat (Jorgensen and Demarais, 1999;Bowman et al, 2001). In summary, a generalist species, with a fine-grained pattern of macrohabitat selection, could potentially show a greater realized niche at the microhabitat scale.…”

“…or deciduous and subtropical forest at low elevation. The close genetic relationship and the recent divergence (5.3 mya) between H. alboniger and H. phayrei suggest that the two populations rapidly extended their ranges to the present distributions in a short time (Jorgensen & Demarais 1999).…”

To elucidate the phylogenetic relationships of Hylopetes, the complete cytochrome-b gene sequences (1,140 bp) were determined from degraded museum specimens for phylogenetic study. The large genetic differences (18.1% to 20.7%) separate Eoglaucomys from Hylopetes as a distinct genus. Phylogenetic relationships reconstructed with maximum parsimony, maximum likelihood, and Bayesian methods show that all Hylopetes were genetically clustered as two major groups, the Indochinese Hylopetes group including H. alboniger and H. phayrei, and the Sundaic group consisting of H. lepidus, H. nigripes, and H. spadiceus. The close genetic relationship and the recent divergence suggest that the Indochinese group rapidly extended to their present distributions with the uplifting of the Himalayas last few million years ago, whereas the oceanic tectonic movements during the Pliocene-Pleistocene resulted in the current geographical distributions of the Sundaic group through alteration of dispersal across the islands of the Sunda Shelf.
