Resumo
O objetivo deste estudo foi conhecer a composição de espécies de formigas epigéicas, nas diferentes estações climáticas do ano; do estrato arbustivo-arbóreo, bem como avaliar se existe correlação entre porte das plantas e riqueza de espécies de formigas e comparar a mirmecofauna em três estratos verticais (solo, arbustivo e arbóreo), em duas fitofisionomias de Cerrado goiano, no município de Ipameri, GO. Para a realização das coletas, em cada fitofisionomia, foram selecionados 30 pontos de amostragens no solo e 30 plantas entre arbustos e árvores distribuídos ao longo de um transecto medindo cerca de 100 m de comprimento. Em cada ponto foi colocada uma armadilha do tipo pitfall, enterrada ao nível do solo, contendo álcool 50% e em cada planta foram colocados dois tipos de iscas, que consistiram de um copo plástico com capacidade de 110 mL, contendo sardinha e a outra contendo mel. Foram realizadas duas coletas por mês, durante um ano, no período de julho/2011 a junho/2012. Quanto á composição de formigas epigéicas, foram coletadas 51 espécies de formigas na fitofisionomia Cerradão, distribuídas em sete subfamílias e, 48 espécies em Cerrado sentido restrito, distribuídas em seis subfamílias. Houve diferença significativa nas constâncias entre as espécies de formigas, entre as estações do ano e para a interação constância das espécies versus estação do ano, em ambas as fitofisionomias. Por meio de curvas de acumulação de espécies, observou-se que o esforço amostral realizado foi satisfatório nos dois ambientes. A riqueza média de espécies estimada não indicou diferença significativa entre as estações. Com relação á composição de espécies do estrato arbustivo-arbóreo, foram coletadas 40 espécies de formigas, distribuídas em 13 gêneros e seis subfamílias em Cerradão e destas, 23 foram consideradas acidentais (z), 10 constantes (w) e sete acessórias (y). Em Cerrado sentido ...
The aim of this study was to determine the species composition of ants epigaeic, in different seasons of the year; the woody layer, and assess whether there ia a correlation between plant height and species richness of ants and ant fauna compare the three strata vertical (soil, shrubs and trees) in two Cerrado goiano physiognomies, in the municipality of Ipameri, GO. To carry out the collections in each vegetation type, 30 sampling sites and 30 plants in the soil between shrubs and trees distributed along a transect measuring about 100 m in length were selected. At each point a trap was placed pitfall of the type buried ground level, containing 50% alcohol in each plant, and two types of lures, which consisted of a plastic cup with a capacity of 110 ml, containing honey and the other containing sardines were placed. Two samples per month were held for one year, between June/2012 July/2011 to. As to the composition epigaeic ants, were collected 51 species of ants distributed in seven subfamilies in Cerradão and 48 species distributed in six subfamilies in Cerrado sensu stricto. There were significant differences between species in the constancy of ants, between the seasons and the interaction of species constancy versus season in both phytophysiognomies. Through species accumulation curves, it was observed that the sampling effort was achieved in both environments. The species richness values estimated indicated no significant difference between the seasons. With respect to the composition of species of woody layer, were collected 40 ant species, distributed in 13 genera and six subfamilies in Cerradão. Of the 40 species collected, 23 were accidental (z), 10 constants (w) and seven accessory (y). In Cerrado sensu stricto, 36 ant species, distributed in 12 genera and six subfamilies were collected. This phytophysiognomy a larger number of accidental species was also detected (18), followed by 11 species constants and seven accessory ...
