Conceivably, some individuals from a population may use matrix habitat and resources in equal or greater proportions to patch resources, thereby obscuring inferences about the influence of forest patch area and edge habitat
on white-footed mouse populations when sampling does not occur outside of the patch.
In spite of potential seed success in this altered area, in the case of forest fragmentation the creation of edge habitats
is responsible for more severe modifications in community dynamics (Murcia, 1995; Saunders et al., 1991).
The results showed field edge habitat
provides significant benefits from beneficial insects and poses low risks to crop production from insect pests and rodents (Morandin et al.
Without human provisioning of food, CN and its mother MN preferred bamboo edge habitats
for higher quality foods (Yu et al.
While it is possible that medium sites contain both species that prefer edge habitat
and species that prefer forest-interior habitat, the overall similarity in species noted between width categories suggest that these potential differences in species richness may be negligible.
Although the Brown country rat is a generalist, the disturbance of road construction can reduce the width of useful edge habitat
for the species.
Hence, we expected to find higher DCP densities in marsh creek or estuarine edge habitats
. Of all observed DCPs, 50% were discovered in marsh creek habitat; however, this finding could result from lower sampling effort overall in ICW habitat or from the lack of appropriate ICW habitat in 2 of the studied waterbodies (Table 1).
since nest predation from corvids tends to increase at edge habitats
(Hannon and Cotterill, 1998), it would be reasonable to expect an increase in warbler nest predation by scrub-jays.
It was towed by hand for 17 m, covering 10 nr of bottom either within the flooded marsh edge habitat
or at a distance of 5 m from the shoreline, parallel to the marsh edge (nonvegetated shallow habitat).
As a result, edge habitat
may receive more incoming reproductive propagules, and edge disturbances may cause more mortality and turnover of individuals.
If small patches are more species-rich than expected, and this increase in species number has been caused by species that are specialized on edge habitats
, then small patches could increase the regional diversity, depending on whether edge habitat
was common or rare before fragmentation (ANDREN, 1994).
Begonias and their cousins Impatiens are shade-loving plants, especially the woodland edge habitat
