Edaphic arthropods in different successional stages of  Atlantic forest and abandoned pasture areas

The vegetation may modifies the structure and composition of the community of edaphic arthropods. This study aimed to compare the community of edaphic arthropods in four areas of abandoned pasture (AP1, AP2, AP3, AP4) and four secondary native forest fragments in a successional gradient (FF1, FF2, FF3, FF4), in Itaboraí, Rio de Janeiro, Brazil. The areas are positioned on the hillside and the sampling was conducted in transects outlined in a toposequence (upper, middle and lower sections), where pitfall traps were installed in the dry season. The organisms were identified in taxonomic groups (class, order and family). Comparing the averages for AP and FF, there was no defined pattern in terms of the response of structural attributes (total abundance, richness, uniformity and diversity). Among the areas of FF, higher values of all of the structural attributes occurred in the intermediate stages of forest succession (FF2, FF3), compared to the initial (FF1) and advanced stages (FF4). On average for the FF, the most favored groups were Archaeognatha, Coleoptera, Entomobryomorpha, Pseudoscorpionida, Psocoptera and Symphypleona. On average for the areas of AP, the most favored groups were Acari, Araneae, Formicidae, Diplopoda and Auchenorrhyncha. Among the areas of FF, Sternorryncha, Symphyla and Thysanura were favored in FF1, while Coleoptera, Psocoptera, Pseudoscorpionida, Entomobryomorpha and Archaeognatha were favored in the other successional stages (FF2, FF3, FF4

R Language

The goal of this work was to calculate landscape ecology metrics using the R language, allowing the analysis of forest fragments under the Atlantic Forest domain located in the sub-basin of Arroio Jaquirana, Rio Grande do Sul, Brazil. For the mapping of the forest fragments, we used images from the REIS/RapidEye sensor dated 2016, and the classification was supervised through the Bhattacharya algorithm. The fragments were analyzed in seven size classes, to separate them and to calculate the landscape metrics it was used R language. The results attained demonstrated that the native forest occupied 34.01% of the study area, covering a total of 1,995 fragments, of which 93.43% were less than 5 ha. The highest values of edge and perimeter-area ratio were found in the small fragments indicating a greater edge effect, with the central areas of these remnants being exposed to the external matrix effects. Thus, it is concluded that the Atlantic Forest is highly fragmented and is extremely important to establish measures to minimize the effects and/or increase the connectivity between the fragments through ecological corridors using the smaller fragments, in addition, it makes necessary the development of public policies and research for the management of the region in order to preserve the remnants.

Resumo. O objetivo deste estudo foi avaliar a contribuição de dois ambientes antrópicos (monocultura de Eucalyptus e pastagem de bovinos) como habitats para espécies de formigas edáficas de Floresta Estacional Decidual (mata nativa). Foram realizadas coletas semanais entre outubro de 2009 e março de 2010 utilizando armadilhas de solo do tipo Pitfall, no município de Santa Cruz do Sul, RS, Brasil. Duas hipóteses foram testadas: (1) a diversidade de formigas é maior na mata nativa em relação a pastagem de bovinos e a monocultura de Eucalyptus; (2) ambientes florestais (mata nativa e monocultura de Eucalyptus) apresentam assembleias de formigas mais similares entre si do que com ambientes abertos (pastagem de bovinos). Foi observado 930 espécimes de formigas, distribuídas em seis subfamílias, 17 gêneros e 28 espécies. As curvas geradas pelos estimadores de espécies indicam que a amostragem foi suficiente. A mata nativa foi mais rica que as outras fitofisionomias, corroborando com a hipótese (1). Embora a pastagem de bovinos tenha sido estatisticamente mais semelhante com a monocultura de Eucalyptus, possivelmente por serem ambientes mais impactados que a mata nativa, houve um alto compartilhamento de espécies entre os ambientes florestais. Esses resultados demonstram a importância da preservação de ambientes naturais como repositórios da mirmecofauna.Contribution of anthropogenic environments as habitats for soil ant from Deciduous Seasonal Forest in Southern BrazilAbstract. The aim of this study was to evaluate the contribution of two anthropic environments (Eucalyptus monoculture and cattle pasture) as habitats for edaphic ant species of Deciduous Seasonal Forest (native forest). Weekly collections were conducted between October 2009 and March 2010 using Pitfall traps, in the municipality of Santa Cruz do Sul, RS, Brazil. Two hypotheses were tested: (1) the diversity of ants is greater in the native forest in relation to cattle pasture and a monoculture of eucalyptus; (2) forest environments (native forest and Eucalyptus monoculture) present ant mounts more similar to each other and with open environments (pasture area). It was observed 930 occurrences of ants, distributed in six subfamilies, 17 genera and 28 species. Curves generated by species estimators indicate that sampling was sufficient. The native forest was richer than the other phytophysiognomies, corroborating with the hypothesis (1). Although the pasture area has been established statistically with the Eucalyptus monoculture, possibly for being environments more impacted than the native forest, there was a high species sharing among the forest environments. These results demonstrate the importance of the preservation of natural environments as repositories of ant fauna.

Successional Stages

With uncontrolled deforestation, forest fragments remain, which in most cases are in different stages of regeneration and present isolated populations. In the present study we analyzed the genetic patterns of Eulaema nigrita populations in seven Atlantic Forest fragments of different sizes and successional stages in the region of Viçosa, MG. This was done by RAPD molecular markers. We observed that the area of the fragments had no effect on the genetic variability of E. nigrita in the direction predicted by meta-population models. Medium-sized well-preserved woods presented the lowest variability, whereas large and small woods were statistically identical. The evidence supports the notion that rural areas present greater dispersal among fragments, implying greater similarity between the populations of fragments located in rural areas when compared to fragments in urban areas.

The soil fauna can be used as a bioindicator of soil quality and ecosystem functioning. The present study aimed to assess the effect of the Atlantic Forest secondary succession on the structure and composition of the soil fauna community in Itaboraí, Rio de Janeiro. We selected five areas along a gradient of forest succession: pasture (PA) and four forest fragments (FF1, FF2, FF3, FF4), which are in a toposequence. Thus, we divided the areas in upper, middle and lower thirds and delimitated a transect (20 m) in each third. In the dry season 2010, a metalic square (0.25 m x 0.25 m) was released in five points spaced 5 m apart, in each transect. The soil fauna was manually captured on samples of the litter standing stock and blocks of the topsoil (0.00-0.10 m), circumscribed to the square, in the forest fragments. In PA, we colected only the topsoil blocks. The complexity of the structure and composition of the soil fauna community increased in the topsoil and litter standing stock, along the successional gradient. However, the similarity among the areas was much greater in the litter standing stock, in comparison to the topsoil.

ABSTRACT In Brazil, the Mantiqueira Range, southeastern region, shelters the last remnants of the ecologically important Upper Montane Tropical Forest. since extensive exploration that has been taking place in this biome for decades, the influence of land-use changes on hydropedology in these areas must be investigated once major land-use changes have been observed. This study aims to evaluate the land-use influence on soil drainable porosity (SDP) in a headwater watershed located in the Mantiqueira Range region, and to validate the proposed methods based on micromorphological and hydrological indicators. The native vegetation of the study area is Atlantic forest that occupies 62% of the area, and the remaining 38% has been used for pasture. Thirty nine combinations of environmental variables were tested, each one generating a map for predicting SDP. The performance of the spatial prediction of SDP was assessed using 20% of the data from the total number of samples collected throughout the watershed. The least values of SDP are due to the process of removal of native forest and replacement by pasture. Areas with high to moderate SDP are associated with native forest fragments demonstrating the effects of the Atlantic Forest on the water infiltration and groundwater recharge processes, given by the greater contribution of baseflow in a forested catchment located within the studied watershed. The analysis of soil micromorphological images provided useful supporting information on the soil porosity system and along with hydrological properties of the watershed helped understand the SDP behavior on subsurface and groundwater storage capacity.

Important Habitat

Abstract: Bromeliads are numerous both in diversity and abundance in the Atlantic Rainforest, one of the most threatened biomes on Earth. They are also an important habitat for several animal species that live in the water retained by its rosette structure. In this study, we aimed to characterize and compare the macroinvertebrate community of two bromeliad species from Atlantic forest fragments. One is characteristic of Dense Ombrophilous Forests, Aechmea ornata, and the other occurs in Mixed Ombrophilous Forests, Aechmea recurvata. We sampled and identified macroinvertebrates form 24 bromeliads, 12 of each species. A total of 19 taxa and 656 specimens were sampled. In both bromeliad species, Diptera was the most abundant insect order (n=417), represented mostly by mosquitoes (n=227) and non-biting midges (n=107), followed by Scirtidae marsh beetles (n=216). Aechmea ornata presented higher abundance and lower invertebrate richness compared to Aechmea recurvata. Seven taxa were exclusive of A. recurvata, eight were common to both, and four, including a sponge, occurred only in A. ornata. The most abundant invertebrate taxa were common to both bromeliads and are regarded as typical of lentic environments. On the other hand, the high number of exclusive species indicates that conservation efforts should include bromeliads from these two phytophysiognomies to secure protecting the diversity of phytotelmata communities.

We present the first lizard species list for the municipality of Juruti, state of Pará, Brazil. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and from inventories conducted in 2008-2011. Sampling methods included pitfall traps with drift fences and time constrained searches. We considered the data collected by other researchers, incidental encounters and records of dead individuals on the road. We recorded 33 species, 26 genera and ten families. Norops tandai was the most abundant species. Compared with the other regions of Amazonia, the region of Juruti presented a large number of lizards. However, further studies with an increase in the sampling effort, could prove this area to be richer in lizards than that observed so far.

Conservation And Management

Subject to overexploitation in past centuries, the Atlantic Forest is now strictly protected, including a ban on timber harvesting. However, this strict protection is a very controversial issue. It resulted in a lack of willingness of landholders to conserve and possibly even expand native forest areas. The lack of knowledge on impacts of potential timber-harvesting causes conflicts between conservation and management of the remnant Atlantic Forest. We believe that sustainable forest management, with reduced harvesting impact, has the potential to generate income for the landowners while sustaining important ecological services of the forest. Therefore, we assessed the harvesting impact of a conventional harvesting method (CM) and compared it to an alternative harvesting method (AM) in three different stands. We measured damage intensities of all remnant trees directly after harvesting and two years after harvesting. Tree damages were recorded in three different tree zones (crown, bole and leaning) and rated in three different intensity classes (minor, moderate and severe). Furthermore, we assessed the recovery and mortality rates of each damaged tree two years after harvesting. Improved AM harvesting reduced the impacts on trees with multiple damages, in particular to crown and bole damages combined. There is a strong relationship between steep terrains and crown damage. High mortality rates were related to stands with a high density of smaller trees and also to trees with leaning damage. Moreover, completely recovered trees were related to trees with light bole damage.
