San Rafael

at 72,849 ha the “Área de Reserva para Parque Nacional San Rafael” (departamentos itapúa and caazapá) is the second largest block of upper paraná atlantic forest remaining in eastern paraguay and widely considered the highest priority for conservation of the endemic atlantic forest avifauna in the country (cartes et al. 2008). the avifauna of the reserve has been well documented (lowen et al. 1996, madroño et al. 1997, Smith et al. 2006, esquivel et al. 2007, esquivel and peris 2011, Smith and clay 2015) with most field effort in recent years concentrated on estancia nueva gambach (pro cosara). detailed descriptions of this locality are provided by cartes (2008), esquivel and peris (2011) and Smith and clay (2015). the San rafael reserve list stands at 426 spe- cies, making it the most ornithologically diverse protected area for birds in paraguay (Smith and clay 2015). here we provide documentation for five additional species which take the park total to 431 species, including two new records for itapúa department and formal documentation of one species for paraguay that was previously known only from literature reports. additionally we provide information on three additional ob- servations of interest.

This paper presents a list of species of butterflies (Lepidoptera: Hesperioidea and Papilionoidea) sampled in Porto Mauá municipality (27°34’S, 28°40’W), Rio Grande do Sul State, Brazil. Sampling was carried out monthly between March 2008 and March 2009. After 204 net-hours of sampling effort, a total of 1,993 individuals from 253 species were recorded. With a single additional expedition, eight new species were added, reaching a total of 261 species recorded in the region of Porto Mauá. These new reports and the species accumulation curves may indicate a much richer fauna. The distribution of richness among butterfly families is compared with other inventories in seasonal semi-deciduous forest areas in the Atlantic Forest. We also discuss the importance of riparian forests of the Uruguay River as an ecological corridor that enables the maintenance of the butterfly fauna on the southern edge of the Upper Paraná Atlantic Forest Ecoregion.

AbstractMost large carnivores are secretive and threatened, and these characteristics pose problems for research on, and monitoring of, these species across extensive areas. Participatory monitoring, however, can be a useful tool for obtaining long-term data across large areas. Pumas Puma concolor and jaguars Panthera onca are the largest predators in the threatened Upper Paraná Atlantic Forest. To survey the presence of these two species we established a participatory network of volunteers and a partnership with researchers in the three countries that share the Upper Paraná Atlantic Forest (Argentina, Brazil and Paraguay). We trained participants in simple methods of collecting faeces and track imprints of large felids. Between 2002 and 2008 > 100 volunteers helped with monitoring, obtaining 1,633 records identified as pumas or jaguars across c. 92,890 km2. We confirmed jaguar presence in a large section of the Misiones Green Corridor in Argentina and in the largest protected areas of Brazil and Paraguay. Pumas exhibited a wider distribution, being recorded throughout Misiones province in Argentina and in some areas of Brazil and Paraguay where jaguars were not detected. Both species, and especially jaguars, were detected mainly in the few remaining medium and large forest fragments in this Forest. Although these carnivores are often in conflict with local people, their charisma and cultural significance makes them flagship species that motivated the participation of volunteers and institutions. Participatory monitoring allowed coverage of a vast area at relatively low cost whilst enhancing collaborative management policies among people and institutions from three countries.

Many questions concerning habitat preferences of Neotropical small mammals remain unanswered. These questions include where the animal lives within and among the available habitats, and the temporal (seasonal and interannual) variation in the habitat associations. The objectives of this research were: (1) to determine the associations of non-volant small mammal species (Rodentia and Didelphimorphia) with specific microhabitat characteristics including vegetation structure in an area near the western boundary of the Upper Paraná Atlantic Forest, and (2) to evaluate seasonal and interannual variation in those associations. Three grids were sampled in three seasons (Dry, Wet, Variable) during two years (2015-2017). The four predominant small mammal species (Gracilinanus agilis, Akodon montensis, Hylaeamys megacephalus, and Oligoryzomys nigripes) were evaluated for seasonal and interannual variation in habitat preferences. Each of the four exhibited seasonal and/or interannual variation in microhabitat preferences for three to six of the 17 environmental variables analyzed. This is the first study to explicitly evaluate temporal variation in habitat associations of small mammals in the Atlantic Forest ecoregion. The temporal patterns of habitat association among these four predominant species reveal a complex spatially and temporally dynamic composition and structure in this small mammal community.

Upper Paraná Atlantic Forest

Agricultural systems result of the coevolution between social and natural systems,  where biodiversity and natural resources play an important role, emerging interactions between crops and the natural environment that allow the development of ecological processes  which interact with external inputs. This research aims to describe the agricultural practices developed by the Guarani  Indigenous  People in the agricultural systems located within the biodiversity corridor of the Upper Paraná Atlantic Forest. This exploratory  study is focused on multiple cases, with a qualitative approach and data were collected during 2017 and 2018 in  eleven  indigenous communities. The main practices developed for the management of biodiversity are polyculture, rotation, and embroideries; they also practice agroforestry and livestock-raising. The main difficulty they face is the reduction of the surrounding biodiversity, which affects the sustainability of the system. This study shows ways for nature-based solutions and ecosystem-based adaptation according to current needs for greening the economy.
