BioNews 9 - October 2013
This month’s issue focuses attention on a very important species group – butterflies. Due to their sensitivity to environmental conditions, butterflies may serve as bioindicators for local and global environmental change. In addition to butterfly inventories and research across our islands, five years of butterfly monitoring on St. Eustatius is beginning to produce clear trends that indicate broader ecosystem change.
Also in this issue, on Saba the seafloor of the well-known site ‘The Pinnacles’ has been surveyed for the third time since 1991, resulting in the most detailed map of the seabed to date, demonstrating the benefit of improving technology for nature conservation(ists).
