“…Besides the classic area and habitat diversity effects (Hecnar and M'Closkey 1997;Wright et al 1998;Honnay et al 1999), human disturbance can promote nestedness in bird communities. Even though the results of this study cannot be generalized to landscapes with different levels of disturbance, some conservation implications can be drawn for areas with increasing human visitation.…”

“…This test yields the probability that the observed sequence of presences and absences differs from a random one (for the advantages of using this test, see Hecnar and M'Closkey 1997). For each species, I performed the test arranging the matrix as to every independent factor.…”

“…Mechanisms promoting nestedness entail selective extinction (Patterson and Atmar 1986;Atmar and Patterson 1993;Lomolino and Davis 1997;Wright et al 1998), selective colonization (Kadmon 1995;Lomolino 1996;Conroy et al 1999), historical effects (Patterson 1990), nested habitats (Wright and Reeves 1992;Hecnar and M'Closkey 1997;Wright et al 1998;Honnay et al 1999), speciation (Cook and Quinn 1995) and differential reproductive success (Blake 1991). These factors may also affect species composition in combination, giving rise to interactive effects; namely, the probabilities of species occurrence decrease in more isolated and smaller fragments (Lomolino and Davis 1997;Lomolino 1999).…”

“…One metric of community structure is nestedness, whereby species inhabiting low species-richness locations are subsets of progressively species-richer ones (Patterson and Atmar 1986). What becomes relevant is not whether a community is nested, as long as nestedness appears to be a common phenomenon (Cook 1995;Boecklen 1997;Wright et al 1998), but what mechanisms promote nestedness in communities with different phylogenetic and ecological attributes (Simberloff and Martin 1991;Lomolino 1996;Worthen and Rohde 1996;Hecnar and M'Closkey 1997;Wright et al 1998).…”

Can human disturbance promote nestedness? A case study with breeding birds in urban habitat fragments

Several factors, singly or in combination, have proven relevant in promoting nestedness in animal communities (area, isolation, habitat structure, etc.); however, little empirical evidence exists about the role of human disturbance. The goal of this paper was to assess whether human disturbance (pedestrians) may affect bird species composition in such a way as to generate a nested distributional pattern. The study was conducted in an urban fragmented landscape, the city of Madrid, where wooded parks were suitable fragments for many bird species, and had different levels of human visitation. At the community level, the distribution of species was significantly nested in two consecutive breeding seasons. Using two different procedures ("temperature" and "departures" methods) to analyse causality in nestedness, I found that pedestrian rate, fragment size and the diversity of stems were significantly correlated to the nested pattern. When analysed simultaneously, and controlling for their independent effects, these factors still accounted for nestedness. Pedestrian rate was the only factor significantly associated with changes in species composition between years. At the individual species level, 74 and 41% of species were significantly nested in relation to pedestrian rate in 1997 and 1998, respectively; however, these percentages were independent of foraging substrate and body size. Besides the classic area and habitat diversity effects, human disturbance can also promote nestedness: locally, by restraining the time and space of foraging and breeding opportunities, thus reducing fragment suitability, and regionally, by increasing extinction and decreasing colonization probabilities in highly disturbed fragments.

“…Changes in the composition and physiognomy of a landscape resulting from habitat loss and fragmentation (Dunning et al, 1992) can alter genetic structure (Gaines et al, 1997), individual behavior (Lima & Zollner, 1996;Sheperd & Swihart, 1995), local population dynamics (Nupp & Swihart, 1996, 1998, interspeci"c interactions (Keyser et al, 1998), and community composition (Dunstan & Fox, 1996;Hecnar & M'Closkey, 1997;Kolozsvary & Swihart, 1999). Not surprisingly, habitat destruction has been implicated as the major threat to biological diversity (Wilcox & Murphy, 1985).…”

Biogeography of Great Basin butterflies: revisiting patterns, paradigms, and climate change scenarios

We used comprehensive data on butterfly distributions from six mountain ranges in the Great Basin to explore three connected biogeographic issues. First, we examined species richness and occurrence patterns both within and among mountain ranges. Only one range had a significant relationship between species richness and area. Relationships between species richness and elevation varied among mountain ranges. Species richness decreased as elevation increased in one range, increased as elevation increased in three ranges, and was not correlated in two ranges. In each range, distributional patterns were nested, but less vagile species did not always exhibit greater nestedness. Second, we compared our work with similar studies of montane mammals. Results from both taxonomic groups suggest that it may be appropriate to modify existing general paradigms of the biogeography of montane faunas in the Great Basin. Third, we revisited and refined previous predictions of how butterfly assemblages in the Great Basin may respond to climate change. The effects of climate change on species richness of montane butterflies may vary considerably among mountain ranges. In several ranges, few if any species apparently would be lost. Neither local species composition nor the potential order of species extirpations appears to be generalizable among ranges.
