Nestedness of desert bat assemblages: species composition patterns in insular and terrestrial landscapes

Nested patterns of community composition exist when species at depauperate sites are subsets of those occurring at sites with more species. Nested subset analysis provides a framework for analyzing species occurrences to determine non-random patterns in community composition and potentially identify mechanisms that may shape faunal assemblages. We examined nested subset structure of desert bat assemblages on 20 islands in the southern Gulf of California and at 27 sites along the Baja California peninsula coast, the presumable source pool for the insular faunas. Nested structure was analyzed using a conservative null model that accounts for expected variation in species richness and species incidence across sites (fixed row and column totals). Associations of nestedness and island traits, such as size and isolation, as well as species traits related to mobility, were assessed to determine the potential role of differential extinction and immigration abilities as mechanisms of nestedness. Bat faunas were significantly nested in both the insular and terrestrial landscape and island size was significantly correlated with nested structure, such that species on smaller islands tended to be subsets of species on larger islands, suggesting that differential extinction vulnerabilities may be important in shaping insular bat faunas. The role of species mobility and immigration abilities is less clearly associated with nestedness in this system. Nestedness in the terrestrial landscape is likely due to stochastic processes related to random placement of individuals and this may also influence nested patterns on islands, but additional data on abundances will be necessary to distinguish among these potential mechanisms.

“…Lesser long-nosed bats appear to be opportunistic foragers and efficient fliers, capable of flight speeds up to 23 kilometers per hour (14 mph) (Sahley et al 1993), and often foraging in flocks. Seasonally available food resources may account for the seasonal movement patterns of the bat.…”

Profiles for High-Priority Species. Focus of the Army Threatened and Endangered Species Research Program

A need arose during the conduct of Threatened and Endangered Species (TES) research for a source of material about the Army's priority TES that would be accessible to (primarily) non-biologist researchers performing various studies on habitat associations using remote sensing, GIS, and other technologies. This is a primer to the characteristics of the species, and why they were of interest to the Army; it also identifies in a preliminary way where the critical gaps were in our knowledge about the TES. This material is intended to be used primarily by research, land management, and training directorate personnel who are not trained biologists, or are not trained with respect to one or more of the species included. The suggested uses include general orientation as to the characteristics and needs of the various species, and awareness of the nature of the potential for Army involvement with them. Although the information presented here is from reliable sources, all references to this document in subsequent reports and publications should be considered secondary, and the original sources should be cited where appropriate. The material may also be provided to contractors who are new to the location or have not worked in the habitats previously.
