Colêmbolos são pequenos artrópodes extremamente abundantes na natureza. São semelhantes a insetos em seu padrão de tagmose, ecologicamente muito importantes e podem ser usados como bioindicadores. Mais de 8.300 espécies já foram descritas no mundo, mas se estima que a riqueza real corresponda a um número muito maior. A Mata Atlântica corresponde ao domínio fitogeográfico mais alterado pela ação antrópica no Brasil, restando menos de 8,5% de sua cobertura original. No Rio Grande do Norte a Mata Atlântica cobre apenas 0,27% do território do Estado. Assim, considerando a importância de se conhecer a fauna de Collembola, sobretudo num ambiente ameaçado como a Mata Atlântica, este trabalho objetivou estudar a riqueza de colêmbolos Entomobryoidea e Symphypleona ocorrentes em dois remanescentes de Mata Atlântica do Rio Grande do Norte através de coletas ativas com aspirador entomológico e passivas com pitfall, durante os períodos de chuva e seca. Foram identificadas 22 espécies de colêmbolos, sendo que destas 19 (mais de 85% do total) são novas para a ciência, incluindo um novo gênero da família Sminthuridae. As coletas realizadas no período chuvoso apresentaram praticamente o dobro de espécies em relação às realizadas no período seco. Este fato possivelmente está associado à dependência dos colêmbolos de umidade, assim como estratégias de resistência a período secos. São descritas quatro novas espécies, incluindo o novo gênero (Trogolaphysa sp.nov., Gen.nov. sp.nov., Szeptyckitheca sp.nov. e Sminthurinus sp.nov.). Este expressivo número de espécies novas identificadas, os novos registros para o gêneros e famílias para a Mata Atlântica do Rio Grande do Norte e a descoberta de um novo gênero corroboram o pressuposto que motivou este trabalho: o Rio Grande do Norte apresenta uma fauna de Collembola desconhecida e potencialmente diversificada. Além disso, foram geradas informações importantes sobre a morfologia das espécies descritas, que por sua vez são de grande importância para a sistemática dos Collembola. O novo gênero descrito faz parte de um visível subgrupo dentro da família Sminthuridae (aqueles com o unguis com cavidade) que aparentemente tem potencial para ser reconhecido futuramente em alguma categoria taxonômica supragenérica.

Springtails are commonly recognized microarthropods edaphic environments. Among the most common (and most visible) forms of these animals are the Entomobryoidea, one of the most diverse groups of springtails. Although more than 8,300 species of Collembola are registered on the globe, in Brazil a little over 310 species are recorded, mostly in the Southeast. In the Northeast, particularly in Rio Grande do Norte, these records are still reduced, even in the Atlantic Forest domain for this admittedly diverse fauna and specifically, for Entomobryoidea. This study aimed to describe new species of Entomobryoidea in urban remnants of Atlantic Forest in Rio Grande do Norte, specifically in Parque das Dunas, Natal in the Environmental Protection Area Genipabu, Extremoz. The collections were made in the months July and August 2012 and January and February 2013, using entomological vacuums and plastic trays. The specimens were identified in the laboratory and described in detail by looking at the literature. In this paper four new species were described Entomobryidae family: Entomobrya sp. nov. 1, Seira sp. nov. 1, Seira sp. nov. 2 and Trogolaphysa sp. nov. 1. Seira sp. nov. 1 has clear similarities to S. paraibensis, however the chaetotaxy of the mesothorax and abdomen IV distinguishes both species. The number of phylogenetic proximity suggests similarities between species. Seira sp. nov. 2 is characterized by its chaetotaxy, mainly in the 'M' head and his mesothorax. There is possibility of a phylogenetic relationship with S. praiana and S. Potiguara due to some similarities. Entomobrya sp. nov. 1 has little resemblance to Brazilian species, from the point of view of color, however there is for the latter detailing the dorsal chaetotaxy, which might obscure evolutionary relationships of proximity. Even so, the main diagnostic feature Entomobrya sp. nov. 1 compared to other species of the genus is the complexity of the chaetotaxy of the fifth abdominal segment. Descriptions of new species of Collembola, potentially endemic to their habitats of occurrence may help to understand the morphological and evolutionary patterns in the sampled taxa, as well as the preservation of the environments in which they were found.

The study of birds represents an important tool for the understanding of the processes involved in behavioral and morphological patterns. The species we have studied belongs to Thamnophilidae family, the third largest family restricted to the Neotropic ecozone. They are popularly known as antbirds and comprise 209 species. A large portion of the species has cryptic behavior, making the acoustic communication an important tool for maintaining contact among birds. Herpsilochmus pectoralis Sclater 1857 has evident sexual dimorphism, measured between 10 and 12 cm height and it is found in forest fragments in the Northeast and it is also categorized as vulnerable to extinction process. This study was conducted in three sandbank fragments on the east coast of the state of Rio Grande do Norte, Brazil. With the help of tape recordings between 2006 and 2012 it was possible to describe and characterize the sing of H. pectoralis. The sing from male birds has more and longer length than the female sing (16% of dimorphism). No differences were found in the dominant frequency between the sexes. We describe four types of calls from this species repertoire. Through capturing with ornithological nets between 2009 and 2012 it was possible to describe and compare the morphology of H. pectoralis. The species have shown lower corporal mass in the dry season. The young birds showed morphometric similarities in comparison to adults. The species has no accentuated dimorphism in their morphometric characteristics. The young ones with flying capabilities have morphometric characteristics of adults, even though they do not show a characteristic adult plumage. The moult pattern in the species is a characteristic of tropical birds, but it shows short reproductive period, typical of temperate species. Even being in the tropical region, the species suffers with seasonal rainfall, which influences their reproductive phenology and moult (remex and rectrix) cycle. Thus, this dissertation provides information on the biology of H. pectoralis to support the understanding of the relationship of this species to the environment and also to know the variations of morphology and vocal aspects, in order to understand patterns and general characteristics of Thamnophilidae.

Feeding is the primary selective pressure in all forms of animals. Nutritional ecological models predict consequences of preferred and non-preferred food consumption on behavioural, physiological and morphological adaptations. At same time, socioecological models infer socio-organizarion patterns based on feeding competition faced by animals. A list of preferred foods, and inferences regarding the intensity of feeding competition and its behavioural consequences are information of much importance for management of populations in fragments. In this work we observed the feeding behavior and spatial positioning of a group of more than 100 blond capuchin monkeys (Sapajus flavius) that inhabit a fragment of Atlantic forest, surrounded by sugarcane plantation. We compared the consumption of different food items with their monthly availability in the area to define the preferred and fallback food items. We recorded the vocalizations of aggression and the inter-individual distance (area of Minimum Convex Polygon/n individuals) to infer the type of food competition experienced by animals. In the year studied the fruit feeding time correlated with top consumed fruit productivity, indicating preference for fruits. Our data indicate that the species Elaeis sp., Cecropia palmata, Inga spp. and Simarouba amara are the preferred food items in the diet. Available all year round and uniformly distributed, sugarcane was a regular item in the diet and its was characterized as a staple fallback food for this group. Although fruits are preferential food items, direct competition rate did not correlate to fruit productivity in the area, maintaining the high rates throughout the year (2.45 events/ hour). The inter-individual distance index positively correlated with rain fall indicating scramble food competition. The number of neighbours of females carrying infants was smaller when fruit productivity is low, indicating that females carrying infants are suffering increased indirect competition. Our data indicates that blond capuchins in this fragment make use of sugar cane as a staple fallback food, which evidence the importance of sugar cane landscape for the survival of this critically endangered capuchin species in fragmented habitats in Northeast Brazil. A preliminary list of preferred and important foods is offered, and can assist in the choice of trees for reforestation, better fragments to be preserved and areas of release and translocation of animals. We did not observe an increase of contest competition while using preferred foods, but when using staple FBF. This may be due the altered environment, which results in high competition food throughout the year. Both the food preference as the social and behavioral consequences of high food competition experienced by animals in this fragment must be accompanied over the years to ensure the survival of this population.

The Atlantic Forest in Rio Grande do Norte (RN) is included in Pernambuco biogeographic sub-region and it is composed by Semi-deciduous Forest, deciduous Forest, Mangrove and Restinga. We assessed the conservation status of Atlantic Forest in the RN through remnants mapping using high resolution satellite images and landscape ecology approaches. We evaluated if there is difference between the north and south coastal regions considering their natural a historical land use differences. We also assessed the influence of the small remnants on landscape cover and configuration. The proportion of the original biome area with remnants larger than 3 hectares is 15.60% for the official governmental limit and is 16.60% for the alternative limit (SNE, 2002). This remnants proportion varies between 0.56 and 46.52% in the hydrographic basins. 89.70% of the remnants are smaller than 50 hectares. Only 6.00% of the remnants are greater than 100 hectares, and these remnants are responsible by 65% of remaining area. The patches with smaller area influence all calculated metrics. The south coastal hydrographic basins have higher percentage of coverage of remnants, larger patch densities and fragments with larger areas than north coastal hydrographic basins. The diffuse drainage basins of the southern coastal have the highest percentage of coverage with remnants. 18.28% and 10% of the biome area are protected by reserves, according to the official governmental and alternative limits respectively. The reserves are mainly of sustainable use (IUCN V-VI). Therefore, the Atlantic Forest in Rio Grande do Norte is in critical situation, with low proportion of remaining area and high fragmentation level. It’s indispensable to biome conservation keep all the remaining area, especially the large remnants, and restore areas to increase remnants proportion and to increase landscape connectivity
