Though climbers have some important roles, the research
works on this group are nearly neglected [7], [28]. Reference
[19] led to renew the interests on this group probably after
[29] and thereafter climber related research began slowly to
increase [13]. Recently, interest on climber related studies has
been notably increased [7]. Some ecological studies on the
climbers are now available from the forests of different
countries [30]-[35].
