A Neotropical snake, Micrurus paraensis Cunha & Nascimento 1973 from east of Pará state, Brazil is described. This snake is found in secondary forest vegetation and remnants of tropical rainforest in Suriname, and Brazil from Pará, Maranhão, Mato Grosso and Rondônia states. Some authors disagree about the validity of the specific status and they prefer to maintain the subspecific status. The objective of this paper is to enlarge the knowledge about M. paraensis morphology with a description of new systematic characters. External morphology of 64 specimens were analyzed. The species is characterized by the number of black bands on body (12 to 21) and by having a black cap beginning on rostral. The hemipenis is long and bifurcated.

Deforestasi atau perubahan fungsi dari hutan menjadi non-hutan berperan dalam perubahan ekosistem dan spesies di dalamnya. Serangga sebagai salah satu fauna di dalamnya merupakan aspek yang menarik untuk dikaji khususnya semut. Tujuan penelitian ini adalah mengidentifikasi peranan-peranan dari genus semut yang ditemukan di ekosistem transformasi. Penelitian dilaksanakan di Desa Bungku, Kecamatan Bajubang, Kabupaten Batanghari, Provinsi Jambi. Metode yang digunakan dalam penelitian ini adalah membuat plot pengamatan secara purposive sampling. Plot pengamatan dipasang di empat eksosistem hutan dengan jumlah masing - masing ekosistem sebanyak empat plot. Setiap plot memiliki lima sub plot yang tersebar di empat eksosistem hutan untuk pemasangan pitfall trap. Teknik pengambilan sampel semut menggunakan pitfall trap di empat ekosistem. Empat ekosistem tersebut yaitu hutan sekunder, perkebunan kelapa sawit, kebun karet, dan hutan karet. Hasil penelitian ditemukan sebanyak 33 genus dari 6 subfamili. Selanjutnya dari 33 genus dikelompokkan berdasarkan peranannya. Berdasarkan peranannya terdapat 46% pencari makan , 36% predator, 3% semut tentara, 3% pemakan bangkai, dan 3% lainnya (semut pemanen/pemetik, omnivora, predator, dan pemakan bangkai). Camponotus sebagai genus dominan memiliki peranan pencari makan, dan Pheidole mempunyai peranan sebagai penghancur biji dan sebagian lainnya adalah omnivora. The Role of Ants in Lowland Tropical Rainforest TransformationAbstractDeforestation or changes functions from forest to non-forest play a role in changing ecosystems and the species within them. Insect as one of the fauna is an interesting aspect to study, especially ants. Aims of this study is to identify the roles of the genus of ants that found in the transformation ecosystem. This study was conducted in Bungku Village, Bajubang District, Batanghari Regency, Jambi. Method used in this study is to make a plot of observation by purposive sampling. Ant sampling techniques use pitfall traps in four ecosystems i.e.. secondary forest, oil palm plantation,rubber plantation, and jungle rubber. This study found 33 genera from 6 subfamilies. Furthermore, 33 genera are grouped based on their roles, i.e. (1) 46% foragers, (2) 36% for predators, (3) 3% for army ants, (4) 3% for scavengers, and (5) 3% for others (harvesting ants, omnivores, predators and scavengers too). Camponotus as the dominant genus has a role for foragers, and Pheidole has a role as a seed destroyer and the other part is omnivorous.

AbstractWe provide information on the diversity of anurans from agroforestry systems in the Colombian Amazon. This area is inserted at the tropical rainforest ecosystem and consists mainly of secondary forest remnants surrounded by crops, grasslands, and agroforestry systems. From February to May 2015, we sampled anurans mainly with visual and auditory surveys. We recorded a total of 1096 individuals of 20 species of anurans from six families at the study area. The relictual forest was the richest environment, followed by Achapo and Cacao agroforestry systems. The Achapo system showed great similarity in species composition with relictual forest, however, the latter presented the highest number of exclusive species, whereas the first presented only two and Cacao system didn’t have any exclusive species. Our results show that the richness can vary between the different types of agroforestry systems and highlight their importance as management tool for anurans conservation in the Colombian Amazon.

Mapping vegetation types through remote sensing images has proved to be effective, especially in large biomes, such as the Brazilian Cerrado, which plays an important role in the context of management and conservation at the agricultural frontier of the Amazon. We tested several combinations of optical and radar images to identify the four dominant vegetation types that are prevalent in the Cerrado area (i.e., cerrado denso, cerradão, gallery forest, and secondary forest). We extracted features from both sources of data such as intensity, grey level co-occurrence matrix, coherence, and polarimetric decompositions using Sentinel 2A, Sentinel 1A, ALOS-PALSAR 2 dual/full polarimetric, and TanDEM-X images during the dry and rainy season of 2017. In order to normalize the analysis of these features, we used principal component analysis and subsequently applied the Random Forest algorithm to evaluate the classification of vegetation types. During the dry season, the overall accuracy ranged from 48 to 83%, and during the dry and rainy seasons it ranged from 41 up to 82%. The classification using Sentinel 2A images during the dry season resulted in the highest overall accuracy and kappa values, followed by the classification that used images from all sensors during the dry and rainy season. Optical images during the dry season were sufficient to map the different types of vegetation in our study area.

ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group composition, population density, and diet of 14 groups at two field sites in southeastern Peru. All sampled groups were found in secondary tropical rainforest, often dominated by native bamboo species. Half of the observed sleeping sites were in bamboo stands, though groups also emerged from cane thickets and lianas. This contrasts with other Aotus studies which have found groups living in tree cavities and lianas. Population density estimates for both sites were 19 and 50 individuals per km2, outside the range previously reported for A. nigriceps (31−34 individuals per km2). We recovered seeds of 12 species from fecal samples over the course of two field seasons, belonging mainly to Cecropiaceae, Piperaceae and Moraceae. Our results suggest that the black-headed night monkey in Peru can survive and even thrive in secondary forest, feeding extensively on pioneer species, occupying a range of forest types, all while living near human settlements.

This study investigated carbon stock in above-ground biomass across different physiognomies in Obafemi Awolowo University tropical rainforest ecosystem. This was with a view of increasing the understanding of carbon cycle in tropical rainforest in Nigeria. Two 20 m x 20 m plots were marked out in the secondary forest, Tectona grandis and Riparian vegetations. Total enumeration was carried out for the living tree, the Diameter at Breast Height (DBH) of trees ≥10 cm were measured at 1.3 m above the ground and height was also determined using a ranging pole and Haga altimeter. Aboveground carbon stocks in standing trees ranged from 218.24 to 318.92 C t ha-1 with the highest value in Tectona grandis plantation. Trees with DBH size class 11-20 cm contributed more to Carbon stock in secondary forest and Tectona grandis plantation, while size class ≥60 cm contributed more in the riparian vegetation. Tectona grandis plantation proved to be better in mitigating carbon in our environment and this result will enhance better estimates of local and regional carbon stock which is crucial to addressing the problems of climate change.
