Collection Methods

Studies on spatial occupation are fundamental to understand amphibian communities. The aim of this study was to record information on the spatial distribution of anurans in the Tejipió forest, state of Pernambuco, Northeastern Brazil. Fieldwork was carried out weekly between October 2011 and April 2012, with daytime and night-time excursions for time-constrained active searching, in forested and open areas, military construction area and water bodies. Pitfall traps and accidental sightings were also used as alternative collection methods. Data were used to calculate richness, rarefaction curves and richness estimators. A total of 21 species were recorded, distributed in six families: Bufonidae (2 spp.); Craugastoridae (1 sp.); Hylidae (8 spp.); Leptodactylidae (8 spp.); Microhylidae (1 sp.) and Phyllomedusidae (1 sp.). Only the species Rhinella jimi was found occupying all sampled habitats in the research area. Adenomera hylaedactyla and Pristimantis ramagii deserve special care in the area because they are specialists, occupying a smaller number of habitats and microhabitats. The community of anurans of the Tejipió forest is similar to those recorded in other areas of the Atlantic Forest at the Pernambuco State, and its knowledge is essential as a basis for conservation of the area. The gradual recovery of this Atlantic Forest remnant would favor the recolonization of fauna and flora and the conservation of local biodiversity.

First Time

The orchid bee fauna of Estação Ecológica de Murici (ESEC Murici), in the state of Alagoas, one of the largest remnants of the Atlantic Rain Forest in northeastern Brazil, was surveyed for the first time. Seven hundred and twenty-one orchid-bee males belonging to 17 species were collected from the 3rd to the 10th of September, 2009. Besides the recently described Eulaema (Apeulaema) felipei Nemésio, 2010, three other species recorded at ESEC Murici deserve further attention: Euglossa amazonica Dressler, 1982b, recorded for the first time outside the Amazon Basin; Euglossa milenae Bembé, 2007 and Euglossa analis Westwood, 1840, both recorded for the first time in the Atlantic Forest of northeastern Brazil north to São Francisco river. These results together with previous samplings in the state of Alagoas reveal that at least 22 orchid-bee species are now known to occur there. Three other species not recorded for Alagoas yet are known from the neighbor states of Sergipe, Pernambuco, and Paraíba. An identification key to all 25 species of Euglossina known to occur in the states of Alagoas, Sergipe, Pernambuco, Paraíba, and Rio Grande do Norte is provided.

Abstract A new species of Trichostrongyloidea (Nematoda: Heligmonellidae), Hassalstrongylus lauroi n. sp., is described from specimens collected from the small intestine of the rodent Hylaeamys seuanezi in the Atlantic Forest of northeastern Brazil (Igrapiúna, state of Bahia). The genus Hassalstrongylus includes 17 species, which parasitize rodents occurring in the Neotropical and Nearctic regions. It differs from the genus Stilestrongylus through its smaller number of ridges in the synlophe and through the size of the genital cone. The main taxonomic characteristics of this new species are the subsymmetrical caudal bursa of type 2-2-1, ray 8 branching out at the base of the dorsal trunk, right lobe smaller than the left, and rays 4 and 5 of robust nature. In addition, the ornamental ray 5 and the robustness of ray 4 on the male caudal bursa, along with the modification of the ridges of the posterior end of the female, allow us to consider the specimens found to be a new species.

Baturité Ridge is an important Atlantic Forest remnant inserted in the Caatinga Morphoclimatic Domain located in the Ceará state, Northeast Brazil. Al­­though this area presents high rates of endemism and has been investigated by many researchers in the past, there was never an investigation regarding local mammals. In this context, this study aims to survey the non-volant mammals of this region to serve as a basis for future ecological and conservation studies. The work was conducted between 2009 and 2014, based on analyses of voucher specimens from zoological collections, capture of specimens in fieldwork, visual and photographic records, and interviews with selected local residents. Altogether, 32 species were documented and seven are present on lists of endangered animals. In addition, interviews indicated that three non-recorded species probably occur in the area and another two were pointed out by local people as locally extinct. Discussions about identification and conservation aspects were presented.

ABSTRACT This paper analyzed the effects of the spatial distribution of the firewood gross production value (GPV) of northeast Brazil through an exploratory approach using spatial data for the period from 1994 to 2013. Identification of spatial clusters in firewood production through the spatial weighting matrices of 2 nearest neighbors and “queen” and “rook” contiguity matrices were used. Based on the analyses, the following can be concluded: there is a positive autocorrelation for firewood GPV; the high-high spatial cluster was formed predominantly in the Bahia region; the high-high spatial cluster, which considers the weight matrix per area, was composed of the Ceará and Pernambuco mesoregions; the low-low spatial cluster consisted of the Sergipe and Alagoas mesoregions; and the low-low cluster, which considers the weight matrix per area, was formed by the Sergipe, Alagoas and Piauí regions.

Abstract We analyzed floristic variations in fern’s metacommunity at the local scale and their relationship with abiotic factors in an Atlantic Forest remnant of northeastern Brazil. Floristic and environmental variations were accessed on ten plots of 10 × 20 m. We performed cluster analyses, based on Bray-Curtis dissimilarity index to establish the floristic relationship. The influence of abiotic factors: luminosity, temperature, relative air humidity and relative soil moisture was evaluated from a redundancy analysis. We found 24 species belonging to 20 genera and 12 families. The fern’s flora showed high floristic heterogeneity (>75% for most of the plot’s associations). The fern’s metacommunity was structured along an abiotic gradient modulated by temperature, luminosity, and relative soil moisture.

We documented the first reports of Ocelot, Leopardus pardalis (Linnaeus, 1758), in the Rio Grande do Norte state, northeastern Brazil. In December 2014, one adult male was road-killed in an Atlantic Forest remnant in São Gonçalo do Amarante municipality. Another three animals were killed by hunters in the Caatinga between 2012 and 2014, in the municipalities of Lajes and Santana do Matos. These records provide important information about the occurrence and distribution and conservation of this mesocarnivore in northeastern South America.

The state of Sergipe has suffered extreme reduction of its Atlantic Forest area in the last decades. The objective of this study is to present an inventory of the Mata do Crasto flora, the largest Atlantic Forest Remnant in Sergipe (approximately 1,000 ha), located in the Municipality of Santa Luzia do Itanhy. An intensive survey was undertaken with monthly plant collections in the study area, for four years (1995 to 1999). Additionally, collections deposited in herbaria were consulted to complete the species list. A total of 324 species were found, belonging to 84 families and 193 genera. This study adds an additional 29 genera and 96 species to the Sergipe flora as new occurrences. The four most speciose families were the Fabaceae (33 species), Rubiaceae (24 species), Myrtaceae (23 species) and Melastomataceae (15 species), that accounted for ca. 30% of the total species. The taxonomic distinction of the area is very similar to three other lowland forests in Northeastern Brazil, although its species composition is quite distinct.

Abstract We analyzed the patterns of infection by helminths in populations of the Gymnophthalmidae lizard Dryadosaura nordestina from three Atlantic Forest fragments in Northeast Brazil. Prevalence and mean intensity of infection by location showed the following results: ARIE Mata de Goiamunduba (60.8 % and 10.4 ± 8), RPPN Engenho Gargaú (83.3 % and 20.8 ± 19.7) and Benjamim Maranhão Botanical Garden (70.4 % and 7.78 ± 5.8). We provide the first records of helminth infection for the lizard D. nordestina, in which three species of nematodes, Aplectana sp., Cosmocerca sp. and Physaloptera lutzi and one trematode Haplometroides odhneri were recovered. Trematodes of the genus Haplometroides were previously known as parasites only in snake and amphisbaenian hosts in South America. Now, our study provides the first record of a species belonging to this genus parasitizing lizards. In conclusion, our study shows that D. nordestina have a depleted helminth fauna (three species at maximum), similar to other studies with lizards of this family in Brazil and that its parasite abundance is related to host snout-vent length, but not to the sex.
