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.

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.

AbstractMons. Antonio Batista Fragoso has been bishop of Crateus in Northeast Brazil for the past ten years. Eighty percent of the 360,000 people in his diocese are impoverished peasants who engage in rudimentary farming. At least half of the peasants are landless. It is among these people that Bishop Fragoso has encouraged the formation of small grassroots Christian communities that are responsible for a profound change in the patterns of Christian living in his diocese. The following is LP's translation of excerpts from a talk that Bishop Fragoso gave to his fellow bishops and priests in Managua in October, 1980. This is the first time it has appeared in English.

Wildlife Populations

Over the past five years, there has been an abundance of interest concerning the ecological effects of major Ontario highways on the habitats and ecosystems of many wildlife populations. The primary concern with multilane, high-traffic freeways is that they typically divide existing habitats into relatively isolated zones. Consequently, this separates individuals within a population from other members of the same population, and also excludes access to many natural resources. The majority of the resultant issues for wildlife fall under three main categories; the collision based mortalities of organisms and the consequences on local residents, the halting of gene flow amongst the wildlife populations, and the physical intrusion and/or noise pollution adversely affecting the quality of habitat for local species. Based on these concerning issues, it is crucial for a sustainable solution to be developed and implemented in appropriate areas within Kingston and the surrounding Frontenac County. Our approach involves an extensive literature review, which will assist us in observing similar problems around the globe, as well as various solutions that have been executed to fix these said problems. Furthermore, we will conduct a thorough investigation of local organizations’ existing studies to obtain relevant data and statistics which will assist us in determining the effects high-traffic freeways have on the surrounding ecological environment. It is through this research that we hope to present valid findings on the multilane highways impact to local ecosystems and landscapes, as well as produce possible planning options for intervention and suggest key areas for further examination.

Spatial Dependence Structure

The spatial characterization of soil attributes is fundamental for the understanding of forest ecosystems. The objective of this work was to develop a geostatistical study of chemical and physical soil attributes at three depths (D1 - 0-20 cm; D2 - 20-50 cm; D3 - 50-100 cm), in an Experimental Hydrographic Micro-catchment entirely covered by Atlantic Forest, in the Mantiqueira Range region, Minas Gerais. All the considered variables presented spatial dependence structure in the three depths, and the largest degrees of spatial dependence were observed for pH in the three depths, soil cation exchange capacity potential in D3, soil organic matter in D1 and D3 and clay and soil bulk density in D2. The method most used for the adjustments of semi-variogram models was the Maximum Likelihood and the most selected model was the Exponential. Furthermore, the ordinary kriging maps allowed good visualization of the spatial distribution of the variables.

Abstract:A comprehensive assessment of the effect of disturbances on tropical and subtropical forests is needed to better understand their impacts on forest structure and diversity. Although taxonomic and functional diversity measures have been successfully adopted in this context, phylogenetic diversity metrics are still poorly explored. We compared the phylogenetic structure of the seed rain and regenerating seedling community in patches of an old-growth Atlantic Forest remnant dominated or not by a ruderal bamboo species, Guadua tagoara. We sampled those patches before and after illegal harvesting of the palm Euterpe edulis thus assessing if the harvesting led to changes in the phylogenetic structure of the seed rain and the regenerating community in both patches. Bamboo-dominated patches showed a significantly higher presence of species in the seed rain that were more distantly related to each other in the phylogeny than expected by chance compared with patches without bamboos, but this difference disappeared after palm-heart harvesting. Contrary to what we expected, we did not find significant changes in the phylogenetic structure of seedlings before or after palm-heart harvesting. The phylogenetic structure at the tips of the phylogeny was random overall. The maintenance of a higher presence of far relatives in the phylogeny of the seedling community suggests, assuming trait conservatism, that despite bamboo dominance and palm-heart harvesting, functional diversity is being preserved at least in the early regenerating stages and in the time frame of the study. However, higher presence of pioneer taxa after palm-heart harvest indicates that this disturbance may lead old-growth areas to earlier successional stages.

Abstract Two species of aphelench, Bursaphelenchus rufipennis n. sp. and Ektaphelenchus obtusus, were isolated from the 'nematangia', cocoon-like structures found at the base of the hind wings of Dendroctonus rufipennis. The nematangia contained adult females of E. obtusus and the dauer juveniles of B. rufipennis n. sp. Only B. rufipennis n. sp. could be cultured on Monilinia fructicola on LGPDA (lactic acid-treated, glycerol-supplemented, potato dextrose agar). The new species of Bursaphelenchus is described and figured and some additional morphological characters are ascribed to E. obtusus, E. josephi, E. sandiaensis, E. smaelus (= E. prolobos) and E. terebranus after examination of type and/or voucher specimens. Bursaphelenchus rufipennis n. sp. has an adult body length of ca 500-1000 μm, medium a ratios (ca 25-38 for females and ca 30-40 for males), b ratios of ca 8-13 (female) and 7-11 (male), c ratios of ca 15-22 (female and male), c′ ratios of ca 3-4 (female) and ca 2-3 (male), and is characterised by three incisures in the lateral field, mitten-shaped spicules and a conical female tail that curves ventrally and possesses a variable tail tip. The new species is morphologically closest to B. corneolus, B. curvicaudatus, B. gerberae, B. paracorneolus and B. talonus. Morphological examination of type and/or voucher specimens of five Ektaphelenchus species revealed coarse transverse body annulation and three pairs of male caudal papillae (except for the two species where males are not described). Clear typological differences were observed among these five Ektaphelenchus species in the structure of the lip region, presence/absence of stylet knobs and male spicule morphology. Although these characters have not been consistently documented in the past, they may be diagnostic for species in the genus. Molecular phylogenetic analysis based on SSU and D2/D3 LSU sequences revealed that B. rufipennis n. sp. was closest to B. paracorneolus and that E. obtusus was closest to species of Ektaphelenchoides and a Cryptaphelenchus sp.
