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.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67155698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":50705,"journal":{"name":"Cerne","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67155814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
