| Abstract | Biodiversity conservation has faced many challenges, especially the conversion of natural areas that
compete with use for agriculture, energy production and mineral extraction. This problem is further
aggravated by lack of knowledge of the biodiversity that exists and the geographical distribution
of different groups. The objectives of our study were to examine the distributional pattern of
Gerromorpha diversity in Brazil, create a map of conservation priority areas, estimate the degree of
protection that the current network of protected areas guarantees to this insect group, and identify
the size thresholds in geographical distributions that would allow species to be protected. We used
species occurrences from the Water Bugs Distributional Database, and we used 19 bioclimatic
variables to build models of the potential distributions of species using the MaxEnt program. Using the
potential model results, we calculated diversity metrics and overlapped them with the current state
and federal “conservation units” (protected areas for biodiversity) in Brazil. Total beta diversity and
turnover portions were separated into two faunistic groups, one in northern and the other in southern
Brazil. The Amazon has higher beta diversity than what was predicted by the null models. We detected
a positive relationship between species distribution area and occurrence in conservation units.
Conservation units with less than 250 km2
do not protect Gerromorpha species. Our results reinforce
the necessity of formulating new conservation strategies for this group, contemplating species with
both restricted and ample distributions, because rare and specialist species are the most harmed by
habitat reduction, given that they are more sensitive to environmental disturbance. | pt_BR |
