Abstract
The objective of this work is to evaluate the effect of fire on ant assemblages in savanna and forest typologies in the Reserva Natural da Serra do Tombador in Cavalcante – Goiás, Brazil. Ant pitfalls traps were installed and subdivided into Burnt Cerrado (BC), Unburnt Cerrado (UC), Burnt Forest (BF) and Unburnt Forest (UF), and the samples were sorted, assembled and identified. The constancy and abundance of individuals, and the frequency of distribution of the genera in the total area and by treatment were evaluated. The UF, BF, UC and BC had 19, 14, 8 and 15 genera, with Jackknife 1 index indicating 18.5, 24.4, 8.9 and 20.4 respectively. The Shannon diversity index for the genera was 0.8462, 0.7604, 0.6448 and 0.5992 for UF, BF, BC and UC respectively. The Cerrado showed greater abundance of individuals and greater ant diversity index in relation to Forest when in presence of fire.
本研究的目的是评估火灾对巴西卡瓦尔坎特(Goiás)自然保护区Serra do Tombador热带稀树草原蚂蚁群落和森林类型的影响。设置蚁陷阱，并将其细分为烧焦的塞拉多(BC)、未烧焦的塞拉多(UC)、烧焦的森林(BF)和未烧焦的森林(UF)，对样品进行分类、组装和鉴定。评价了该属在总面积和处理范围内的分布频率、个体的稳定性和丰度。UF、BF、UC和BC分别有19、14、8和15个属，其Jackknife 1指数分别为18.5、24.4、8.9和20.4。UF、BF、BC和UC的Shannon多样性指数分别为0.8462、0.7604、0.6448和0.5992。与森林相比，塞拉多在火灾条件下表现出更高的个体丰度和蚂蚁多样性指数。
