Monitoring Effect of Fire on Ant Assemblages in Brazilian Rupestrian Grasslands: Contrasting Effects on Ground and Arboreal Fauna

Abstract: Fire is one of the most relevant ecological disturbances in nature. Little is known about the effects of fire on biodiversity in ecosystems like rupestrian grasslands, which share characteristics with savanna and forest biomes. Brazilian rupestrian grasslands are part of an endangered ecosystem that has been modified by anthropogenic fire events that have become more intense in recent decades. In this study, we evaluated the effects of fire on ground and arboreal ant assemblages through a two-year monitoring p… Show more

“…This group of plant species represents most angiosperms (Moles et al ) and, although diaspores can be primarily dispersed by vertebrates, most of diaspore dispersal outcome rely on the secondary dispersal services provided by non‐vertebrate dispersers, mainly ants (Pizo and Oliveira , Christianini and Oliveira , , Magalhães et al ). These invertebrates are highly resilient to habitat disturbance (Anjos et al , Oliveira et al , Andersen ) and, because of it, can exert disproportional effect on the demography of plant species occurring in vertebrate‐free habitats. Therefore, understanding more about the role of invertebrates as secondary disperser in vertebrate‐free conditions seems to be an important step to improve our knowledge about the functioning of seed dispersal in human‐depauperated habitats.…”

“…Meanwhile, the slight variation among the variables belonging to the native sites was mainly due to the geological history of the place. Certain species that inhabit areas where fire is a part of the system are expected to be resistant and resilient to conflagration such as those that happen in the Brazilian savanna and Rupestrian grassland (Anjos et al, 2017). In addition, areas with low vegetation, such as grasslands, are dominated mainly by ground ants.…”

“…The soil temperature does not change significantly below 5cm. underground in the savannas (Anjos et al, 2017), which would explain why the ants are protected from the fire. Moreover, the fire completely eliminated the leaf litter produced by the Acacia.…”

“…Ants (Hymenoptera: Formicidae) are widely used as a bioindication tool for assessing the effects of environmental disturbance on biodiversity (Majer 1983; Anjos et al . 2017a; Martello et al . 2018), given that ants are highly sensitive to habitat, have high diversity, high sampling facility, and are a taxonomically well‐resolved group (Majer 1983; Ribas et al .…”
