1.      As a result of human activity (such as logging), large forests are becoming fragmented into several smaller forests.

a)      How might the increasing isolation of population in these forests influence their evolution?

b)      How might the fragmentation affect the evolution of a large mammal, like a moose, compared to a small invertebrate, like a worm?

the isolation of the population will lead to low level of logging thus increasing the forest evolution.

the fragmentation of forests will lead to shifting of large mamals like moose and leave the small invertebrates like worms still attached to the few remaining forest reserves.

I dont get the second answer.

How will the fragmentations lead to 'shifting' of large mammals like a moose?

explain what you mean by 'shifting'

and how will it leave small invertebrates like worms still 'attached' to the few remaining forest reserves?

explain what you mean by 'attached'

the large mammals will have no shelter to support them, thus forcing them to move in search of shelter,

while the small invertebrate like worms will have minimal habitat to support their livelihood due to the logging.

so are you saying that both a large mammal like a moose and a small invertebrate like a worm would be negatively affected by forest fragmentation?

May 28th, 2015

yes it will lead to negative effects.
