Quantifying edge effects: the role of habitat contrast and species specialization

Dung beetle persistence in human-modified landscapes: Combining indicator species with anthropogenic land use and fragmentation-related effects

“…These statements are in accordance with the notion that dung beetle assemblages are sensitive to habitat loss (Klein, 1989) and the creation of forest edges, due to the fact that a considerable number of species are forest-dependent or forest-interior specialist species (Filgueiras et al, 2011). Many others are able to eventually exploit forest edges and the surrounding matrix for additional resources (Prevedello et al, 2012), while others are matrix or even edge-specialists (Peyras et al, 2013). Such ecological composition suggests that HMLs are able to retain a significant proportion of dung beetle fauna, although forest interior represents an irreplaceable habitat (Gardner et al, 2008) as shown by the indicator species analysis.…”

Temporal persistence of edge effects on bryophytes within harvested forests

“…Decreasing MFI with succession has been documented for forest beetle species (Barnes et al, 2014;Fountain-Jones et al, 2015), but temporal changes in MFI are unknown for other taxa. Temporal decreases in the magnitude of interior edge effects (Matlack, 1993;Harper and Macdonald, 2002) are typically associated with declining patch contrast (Dodonov et al, 2013;Peyras et al, 2013). A decline in patch contrast was observed in the bryophyte flora of the current study, with regeneration forest communities becoming more similar to mature forest communities through time.…”

Edge effects on dung beetle assemblages in an Andean mosaic of forest and coffee plantations

“…In some species, a common response to the presence of a hard edge is a sigmoid pattern, where abundance decreases from the preferred toward the non‐preferred habitat and penetration distance into the non‐preferred habitat is <60 m (Peyras et al . , Barnes et al . ).…”
