Background: Monodominant Eremanthus erythropappus forests are dispersed in neotropical montane regions of southeastern and northeastern Brazil, forming ecotonal areas among other high altitude phytophysiognomies, with no information from their fauna communities and how these communities vary between phytophysiognomies adjacent. We examined the bird community of three preserved and three managed E. erythropappus forests, and compared them two other coexisting phytophysiognomies (cloud forests and montane fields), being three samples of each, in an ecotonal region between two biodiversity hotspot domains (Cerrado and Atlantic Forest), in southeastern Brazil (1300 to 1570m high). Results: The bird community of the natural E. erythropappus forests was shared with other vegetation, while the managed E. erythropappus forests presented the lowest species richness. However, even though managed E. erythropappus forests has almost no exclusive elements, their community caused a balanced variation (a set of very similar species, only changing the representativeness), suggesting that the abundance of the registered species varies along these phytophysiognomies. Conclusion: The species associated with the natural E. erythropappus forests represented 50% of the total species, in contrast to the remaining 50% associated with the areas of cloud forests and montane fields, and their sharing behaves as an ecotonal community, since its community coincides with elements which are also present in the avifauna of the other two sampled phytophysiognomies. The composition of the avifauna from managed E. erythropappus forests was more similar to the community registered in the montane fields.

Background: The objective of this study was the genetic characterization of remaining populations of the species Paratecoma peroba occurring in fragments of the Atlantic Forest, by estimating parameters of diversity and genetic structure. The study was carried out in two forest fragments, the Atlantic Forest Environmental Education Pole (area 1) and the Pacotuba National Forest (area 2), where 93 adult trees were identified. Results: Ten Inter Simple Sequence Repeats (ISSR) primers were used in genotyping, obtaining 112 amplified bands with 87.5% polymorphism. The genetic diversity estimated for the populations from the Nei (H*) and Shannon (I*) indices was higher for area 1. For the joint data, moderate genetic diversity was observed, referring to the average values of 0.26 and 0.40, obtained for the H* and I* indices, respectively. Molecular variance analysis resulted in moderate differentiation between populations ( Φ ST = 0.143), while gene flow analysis (N m = 6.69) revealed the occurrence of similar alleles between them. However, the predominance of a single genetic group in area 2, revealed from Bayesian approach, indicates that its genetic structure, possibly generated by the current scenario of fragmentation of the Atlantic Forest and the distancing of populations, affecting the contemporary gene flow. Conclusion: Despite the moderate genetic diversity of the species for the area 2 population, actions toward inclusion of seedlings obtained from seeds from neighboring fragments, including area 1, and the increase in the connectivity of forest fragments through ecological corridors, could assist in augmenting its genetic variation.
背景:本研究的目的是通过估算大西洋森林片段中Paratecoma peroba物种的多样性和遗传结构参数，对其剩余种群进行遗传表征。这项研究是在大西洋森林环境教育极点(第1区)和Pacotuba国家森林(第2区)两个森林片段中进行的，在那里发现了93棵成年树。结果:利用10条ISSR引物进行基因分型，得到112条扩增带，多态性为87.5%。用Nei (H*)和Shannon (I*)指数估算的种群遗传多样性在1区较高。联合数据的遗传多样性为中等，H*和I*指数的平均值分别为0.26和0.40。分子方差分析显示群体间存在中等分化(Φ ST = 0.143)，基因流分析显示群体间存在相似等位基因(N m = 6.69)。然而，贝叶斯方法揭示了2区单一遗传群体的优势，表明其遗传结构可能是由大西洋森林破碎化和种群距离的当前情景产生的，影响了当代基因流动。结论:尽管2区种群的遗传多样性处于中等水平，但通过引入邻近片段(包括1区)种子获得的幼苗，以及通过生态廊道增加森林片段之间的连通性，有助于增加其遗传多样性。
