Reintroducing the red-billed curassow in Brazil: Population viability analysis points to potential success

Reintroduction can be enhanced by data from long-term post-release monitoring, which allows for modeling opportunities such as population viability analysis (PVA). PVA-relevant data were gathered via long-term monitoring of reintroduced red-billed curassows at the Guapiacu Ecological Reserve (REGUA), located in Rio de Janeiro, Brazil, over 25 months. In the present article, we (1) assess the robustness of the reintroduction plan, (2) evaluate the viability of the current reintroduced population, and (3) examine mitigation options to increase the viability of this population. VORTEX indicates that the initial plan, fully implemented, was likely to establish a viable population at REGUA. The current population is unviable; the best mitigation strategies are to eliminate hunting altogether, or at least reduce it by half, and to supplement ten immature pairs in 2015. A positive long-term outcome at REGUA is still possible; we encourage the Brazilian government and private stakeholders to consider population supplementation, both to achieve success at REGUA and to improve the evidence base for future reintroductions.

Influência do enriquecimento ambiental nos padrões comportamentais de Galictis cuja, furão-pequeno, mantidos em cativeiro no zoológico municipal de Piracicaba, SP

Currently zoos and management centers are valuable tools in the maintenance and study of various species. Studies of behavior of captive animals contribute to the improvement of management techniques and the well - being of themselves, encouraging captive breeding and reintroduction also to the natural environment . One of the ways to increase the levels of well-being is the use of environmental enrichment techniques that provide necessary incentives for the welfare of both physical and psychological captive animal . The aim of this study was to identify the types, frequencies and intensities of behavior displayed by three individuals of the species Galictis cuja, belonging to the family Mustelidae and popularly known as lesser grisson , which are captives in municipal zoo in Piracicaba , SP . In addition to evaluating the influence of environmental enrichment techniques on these behavioral parameters. The animals had their behaviors recorded in ethograms through the focal sampling method , 40 hours per person , totaling 120 hours of observation . Were introduced four environmental enrichment techniques related to physical environment, nutrition , perception and cognitive stimulation . At the end, the results of observations before and after the introduction of enrichment techniques were compared and it was possible to observe significant changes in behavior such as run , walk and scratching . The animals were more active and spent longer visible during the day, the enrichment also increased the frequency of social behaviors and the end of the work occurred even attempted copulation , thus showing that the enrichment exerted a positive influence on the behavioral patterns of lesser grisson (Galictis cuja)

Genetic erosion risk by environmental and antropic factor applied on strategies for Lychnophora ericoides conservation

This study evaluated the genetic erosion risk factors and the strategic points for the conservation of Lychnophora ericoides population in “Paraíso Perdido” farm, Serra da Canastra (20° 37’ 54” S; 46° 19’ 37” W; 833 m height) in São João Batista do Glória City, Minas Gerais State, Brazil. The number of young and adult plants, the soil and the phenology were evaluated in two sample areas of 125 m2. Information about the species utilization was obtained with local informants. Data on the region were obtained through literature review, in loco evaluation, GPS and geo-referenced map. In addition, local use of the plant for mixtures of drug was evaluated. According to the results obtained, the soil of the population is lithic with a weathered portion of frank-sandy texture, very acidic and dystrophic. The population density is 0.16 individuals/m2, 0.078 young/adult plant. The predominant phenophase was fruiting (100% plants) followed by flowering (21.62% plants). The local community uses the leaves of the plant in the form of hydroalcoholic extracts, as anti-inflammatory. Based on the evaluated parameters, the population is at 73% risk of genetic erosion. The detected key points were the development of activities including the participation of the local community for habitat protection as well as germplasm collection, seedlings production and reintroduction, together with environmental education, supervision, and reduction in the propensity for fire.
