Much more needs to be understood about forest fragments, however.

However, all of these are forest fragments, and ongoing deforestation threatens the species' survival.

It is found within 27 forest fragments along a 60 km stretch of floodplain forests.

"In some of the small forest fragments that have very few birds in them, this may very well be happening right now."

The species lives in both primary and secondary forest, including forest fragments within grassland.

Some of those forest fragments hold no more than 10 gibbons, a number that cannot sustain itself.

The researchers propose instead to move animals between forest fragments to increase genetic diversity within the central groups.

Secondary forests may also buffer edge effects around mature forest fragments and increase connectivity between them.

So this study suggests that by providing other bee species, forest fragments near crop areas can help keep the pollination going.

The maples take enthusiastically to both the forest fragments and the deforested patches between.
