The rise in energetic demand in undeveloped countries is increasing the planning
of new hydropower plants in the Amazon basin. Thus, there is an urgent need to
increase the knowledge over how this mega-dam projects can affect Amazon
biodiversity. Though the fragmentation effects have been extensively evaluated
on bat, few gave attention to how bat assemblage are impacted on islands
created after the dam reservoir has been filled up. In this study, we evaluated
how local and landscape variables effect in the structuration of aerial
insectivorous bat assemblages in the islands of the Balbina Hydroelectric Dam
reservoir. Bat were sampled using autonomous recording station for five
consecutively nights, on 28 forestry islands and 6 mainland plots. Bats were
strongly affected by the insularization and the assemblages answered in both
landscape and local scale. The high matrix contrast and the habitat quality decay
in small islands, added to ecological characteristics of each species, led to aerial
insectivorous bat assemblages to have a strong turn over patterns governed by
island size. |
