Effects of habitat configuration and quality on species richness and distribution in fragmented forest patches near Rome

Abstract: Question: How important are habitat configuration, quality, history and anthropic disturbance in determining nemoral plant species richness and distribution of fragmented forest patches in a Mediterranean region? Location: Agricultural landscape north of Rome, Italy. Methods: Sixty-nine woodland patches, identified through a stratified random sampling, were sampled for nemoral plant species. The homogeneity of woodlands was tested through a hierarchical classification of the floristic data and a Mann-Whitney t… Show more

“…The effect of fragmentation on species richness and community composition in forests is mediated by four main groups of variables: (1) forest patch quality in terms of soil variables, notably pH, nutrient availability and light [11,49]; (2) patch heterogeneity, i.e. the variability of environmental drivers and stand diversity [50,51]; (3) habitat configuration in terms of forest patch size and isolation [49,52]; and (4) the history of the patch, especially whether it has been continuously forested for centuries (ancient forest) or afforested on agricultural land (recent forest) [52,53]. Generally, the number of species in SFP increases with increasing patch area, decreasing isolation, increasing heterogeneity and temporal continuity, while the effects of patch quality are more complex and often species specific.…”

“…Most studies dealing with the influence of age of forest establishment on floristic patterns focus on temperate or boreal regions of Europe and North America, while studies in the Mediterranean region are scarce (see De Sanctis et al, 2010;De Frenne et al, 2011). In the Mediterranean region, forest ecosystems, and the open habitats in which the secondary forests grow, are markedly different from those in Northern and Central Europe due to the different climate, biogeography, ecology and history of human disturbance (Qu ezel, 1983;Grove & Rackham, 2001;Blondel et al, 2010).…”

“…The loss of suitable habitats accounts for the extinction of many plant species in the Neotropics (Fahrig, 2003;De Sanctis et al, 2010). Our data showed that there were instances in which small fragments harbored large populations of P. hastisepala, whereas large fragments contained a small number of plants.…”

“…Moreover, forest management practices and land conversion to agriculture are factors that contribute significantly to extinctions at local scale given that they reduce both habitat quality (De Sanctis, Afo, Francesconi & Bruno, 2010) and population size of native species (Aizen & Feinsinger, 1994). When compared to continuous forests, isolated forest fragments harbor low levels of genetic diversity owing mostly to limited gene flow and genetic drift (Frankham, Ballou & Bruno, 2002).…”
