RESUMO:

Neotropical mountain ecosystems are recognized for their high biodiversity and notable
species endemism but are increasingly threatened by anthropogenic pressures resulting from
historical and ongoing human activities. These pressures, combined with limited ecological
knowledge, have hindered the development of effective conservation strategies for these
vulnerable biomes. The present research addresses this problematic in two chapters. The first
chapter addresses a critical challenge, related to the variability in biodiversity responses to
anthropogenic impacts reported in localized studies. Insects were selected as the focal group
due to their exceptional diversity, critical ecological roles, and increasing vulnerability to
environmental changes. I performed a meta-analysis to evaluate insect responses to different
types of anthropogenic impacts. I assessed how insect group, type of natural habitat
transformed, characteristics of anthropogenic transformation, and geographical variables
influenced insect responses. The results show how habitat transformation has negative effects
on insect communities in Neotropical mountains. It also shows how ants, and dung beetles
can be more affected by impacts. Furthermore, these impacts were more severe for agriculture
and livestock, in equatorial regions, and at lower altitudes. The second chapter, address how
the management characteristics and landscape connectivity, influence the dung beetle
response due to natural forest conversion to coffee plantations in the tropical Andes
mountains. The results reveal how coffee plantations present lower taxonomic and functional
dung beetle diversity. However, shaded system and connectivity to natural forest supports
higher taxonomic and functional diversity of dung beetles. The pronounced negative impacts
of anthropogenic pressures on Neotropical montane insects highlight the urgent need to
prioritize natural habitat protection in future conservation programs. These findings provide
valuable insights for structuring effective conservation programs in the Neotropical region,
where human development and its associated impacts must be integrated into future
sustainable systems aimed at conserving biodiversity.
