“…The task is particularly challenging when this species is investigated within one of the most endangered major biomes worldwide, the Atlantic Forest. This biome is under current conditions of severe habitat alteration and fragmentation (Grelle et al, 2021). In our study, jaguars occurred at low density within the entire RDSP area (0.11 ind./100 km 2 according to the estimates from the random survey design).…”

The jaguar (Panthera onca) plays an important role in maintaining biodiversity and ecological processes. We evaluated the status of a jaguar population in one of the last stronghold habitats for its conservation in the Atlantic Forest, the Rio Doce State Park (RDSP). We used a random survey design from 2016/17 to estimate jaguar abundance and density as well as its occupancy and detection probabilities in the entire Park's area. To monitor for temporal fluctuations in density and abundance, we used a systematic survey design in the southern portion of the Park where jaguars were more recorded when using the random approach. We then conducted two surveys in 2017/18 and 2020. Our 2016/17 random survey revealed that jaguar density (0.11 ± SE 0.28 individuals/100 km2) was the lowest obtained for the species across the Atlantic Forest. We noticed that jaguar density increased three times from 2017/18 (0.55 ± SE 0.45 individuals/100 km2) to 2020 (1.61 ± SE 0.6 individuals/100 km2). Jaguar occupancy and detection probability were 0.40 and 0.08, respectively. The low jaguar occupancy probability was positively associated with smaller distances from lakes and records of potential prey. The detection probability was positively associated with prey detection, the rainy season, and smaller distances from lakes. Our work contributes to a growing awareness of the potential conservation value of a protected area in a human‐dominated landscape as one of the last strongholds for jaguars across the Atlantic Forest.

“…Land use and land cover change increased over the last 70 years [4,5] bringing consequences to plants [6] and vertebrates species [7–9]. Consequently, many conservation initiatives were developed, including the creation of national and state protected areas (categories I–VI of IUCN), private protected areas (RPPNs in Portuguese acronym), corridors and action plans for protected species [10–14]. Besides being the first place to be occupied and explored by Europeans, the Atlantic Forest is home of at least 150 million people and is the main industrial centre, responsible for 80% of Brazil's gross domestic product (GDP) [15].…”

Sustainability issues in a tropical mega trail

Sustainability is a target that involves many socio-ecological questions, depends on opportunities and combines different initiatives. This can be especially difficult in regions with high biodiversity scores, mega cities, high level of human populations and an intense and long-standing land use. Here, we show how a mega trail, named Atlantic Forest Trail, within the Brazilian Atlantic Forest can join the protection of biodiversity and sustainable tourism through a 4270 km corridor connecting protected areas and crossing a variety of landscapes. Further, we show some initiatives of ongoing biodiversity monitoring, and an analysis of ecological restoration in private lands that can be applied in many regions to improve habitat connectivity for both biodiversity and human use.

The success of restoration projects depends upon the genetic diversity of the implanted species. It is a limiting factor, often because the seed sources are immersed in highly fragmented landscapes. This work was carried out to compare the genetic diversities of the juveniles and the adult trees of Schinus terebinthifolia Raddi in a mixed reforestation area, both in the restoration process and in the remaining natural area in the Atlantic Forest. Through ve SSR primers, it was observed that the implanted population showed a greater genetic diversity index (He) (0.553 adults and 0.505 juveniles) when compared to the wild population (0.487 adults and 0.483 juveniles). It indicated that the forested area was established with individuals of high genetic diversity. There was a reduction of genetic diversity, with the loss of exclusive alleles and maintenance of inbreeding and coancestry in the juveniles of the reforested population. It can be inferred that there was a low gene ow among the fragments. The effective population size in both populations (adults and juveniles) was lower than that recommended for conserving populations in the short and long terms. These results have shown that continuous monitoring of this particular area is of absolute necessity and for applying techniques that can promote the connectivity of the fragments. It would allow for a more signi cant reduction of genetic drift and the persistence of the planted populations.
