The Pedra Branca Forest is located in a highly-urbanised region of the central portion of Rio de Janeiro City, comprises the largest urban forest on the continent and is isolated from other Atlantic Forest remnants. The local flora and fauna are protected by three conservation units (Pedra Branca State Park, Prainha Municipal Natural Park and Guaratiba State Biological Reserve) and one biological station (Fiocruz Atlantic Forest Biological Station—EFMA). Here, we provide an updated list of the bat fauna for the remnant. The results are based on samplings at EFMA and literature data from Pedra Branca State Park and Prainha Natural Park. The three sampling sites combined resulted in 31 species, 23 genera and four families. Phyllostomidae was the richest family with 24 species, followed by Vespertilionidae with five species (3%) and Molossidae and Noctilionidae with one species. The local bat fauna was predominantly composed of species with a broad geographic distribution.

AbstractTropical forests are being deforested worldwide, and the remaining fragments are suffering from biomass and biodiversity erosion. Quantifying this erosion is challenging because ground data on tropical biodiversity and biomass are often sparse. Here, we use an unprecedented dataset of 1819 field surveys covering the entire Atlantic Forest biodiversity hotspot. We show that 83−85% of the surveys presented losses in forest biomass and tree species richness, functional traits, and conservation value. On average, forest fragments have 25−32% less biomass, 23−31% fewer species, and 33, 36, and 42% fewer individuals of late-successional, large-seeded, and endemic species, respectively. Biodiversity and biomass erosion are lower inside strictly protected conservation units, particularly in large ones. We estimate that biomass erosion across the Atlantic Forest remnants is equivalent to the loss of 55−70 thousand km2 of forests or US$2.3−2.6 billion in carbon credits. These figures have direct implications on mechanisms of climate change mitigation.

The genus Zachaenus Cope is the least specious within Cycloramphidae, including two species: Z. carvalhoi Izecksohn, and Z. parvulus (Girard). Both are leaf litter species distributed across Atlantic forest remnants in Southeastern Brazil. Zachaenus carvalhoi occurs westerly in the states of Espírito Santo and Minas Gerais, and Z. parvulus easterly in the states of São Paulo, Rio de Janeiro, and Espírito Santo (Verdade et al. 2009; Motta et al. 2010; Salles & Maciel 2010; Oliveira et al. 2012; Guedes et al. 2019; Frost 2019). Both species build terrestrial nests, and larval development is endotrophic nidicolous (reproductive mode 21 after Haddad & Prado 2005; Lutz 1944; Thibaudeau & Altig 1999; Zocca et al. 2014). In this work, we describe the tadpoles of Z. carvalhoi, and discuss morphological aspects regarding other endotrophic tadpoles.

The state of Rio de Janeiro has been degraded mainly in lowlands, where protected areas harboring most remaining forests are located. The present study aimed to assess the application of compensatory measures (CM) to restore the vegetation of the Bosque da Barra Municipal Natural Park. We analyzed the survival of planted specimens by dividing the area into six quadrants with approximately nove hectares each. For the analysis, we used a frequency class method and assessed the success rate per quadrant, where 2,125 seedlings of 73 native restinga species were planted. We found 1,245 seedlings, which corresponded to 59% of the planting. Among those seedlings, 885 were alive, which represented a survival rate of 42%. The average survival per species was 26%. Forty-seven species survived out of 73 planted species. All in all, environmental compensation is an important public policy tool, and this legal device should be used to ensure the restoration of environmental damages, aiming to maintain what establishes the 225th article of the Federal Constitution for present and future generations.

We describe, illustrate and compare three new Brazilian species of Senegalia from the Atlantic Forest domain: Senegalia atlantica, from Rio de Janeiro State; Senegalia rafinesqueana, from the state of Paraná; and Senegalia cupuliformis, from Bahia State. These species are morphologically most similar to S. tenuifolia and S. multipinnata, S. velutina, and S. kuhlmannii, respectively. Additionally, we provide an identification key to all Senegalia species that are morphologically similar to S. atlantica, S. rafinesqueana and S. cupuliformis and occur in the Atlantic Forest domain; we also provide comments on the geographic distribution and the flowering and fruiting period of S. atlantica, S. rafinesqueana and S. cupuliformis.

Data on geographic distribution and ecology are essential when defining the conservation status of a species. Herein, we present new information about the geographic distribution, habitat and advertisement call of Ischnocnema henselii, an endemic species of the southern Atlantic Forest. We conducted this study in forest fragments in the state of Santa Catarina, Southern Brazil, from January 2008 to November 2012. We recorded I. henselii in eight fragments over 100 ha in size, both inside and outside conservation units. We often observed less than 20 males in calling activity. The calling activity was daytime and nighttime, and more intense in the rain. We observed individuals perched on vegetation, on leaves or branches, on the leaf litter or under tree trunks. Duration of advertisement calls ranged from 14.71 ± 1.68 s (n = 11 calls) and interval between notes was 0.22 ± 0.13 s (n = 99 notes). We observed that the advertisement calls had a feature that we call "alternating modulation" in the amplitude of the notes. We suggest that further bioacoustic studies should analyze the relevance of this alternating modulation, to understand its role in communication. Although I. henselii is a habitat specialist, it is currently considered a common species, classified as Least Concern by Brazilian and IUCN lists. In the region studied, characterized by small and isolated remnants of the Atlantic Forest, I. henselii is not an abundant species and its spatial distribution is always associated with wet forest fragments. The increasing degradation of forest remnants in this region causes microclimatic and structural changes that may compromise the permanence of strictly forest and moisture-dependent species for reproduction, such as I. henselii.

Ant Diversity

Abstract The knowledge of ant assemblages that occurs in Conservation Units in the Atlantic Forest domain is a priority, considering the number of endemic species and the impacts that this biome has been suffering. The aim of this study was to evaluate ant assemblages in the Turvo State Park, which is the largest conservation unit in the State of Rio Grande do Sul and presents an important role on biodiversity protection. Two samplings were conducted in 2019, one in the summer (January) and the other in the spring (November and December), at five sites 2 km apart, with pitfall traps (soil and canopy), sardine baits, glucose, beating net, sweeping net and manual collection. We sampled 121 species in the summer and 120 in the spring, totaling 163 ant species. A total of 78 species (47.8%) occurred in both sampling seasons. The richest genera in the study were Camponotus (S = 30), Pheidole (S = 23) and Linepithema (S = 11). Seventeen species were recorded for the first time for Rio Grande do Sul state. The results indicate that this is one of the most species-rich assemblages of ants ever surveyed in a conservation unit in southern Brazil. The study highlights the importance of Conservation Units as protected environments against habitat loss for ant biodiversity. The results of this study contribute to myrmecofauna knowledge and serve as a basis for environmental impact studies, management plans and conservation of Atlantic Forest remnants.

ABSTRACT The Atlantic Forest is home to the largest urban centers in Brazil, which modify various aspects of the natural quality of this forest. Soil chemical elements from three different sites in the Atlantic Forest in the state of Rio de Janeiro were analyzed: (1) the best-preserved remnant of Atlantic Forest in the state; (2) the largest urban forest in the world; and (3) an arboretum along the main vehicle route in the second-largest city in Brazil. Energy dispersive X-ray fluorescence (EDXRF) analysis detected sixteen chemical elements including nutrient components and potentially toxic elements. The urban soil had a higher concentration of heavy metals. There was a significant concentration gradient of copper and lead from the urban site to the furthest forest site. We emphasize that the results indicate potential negative consequences for the conservation of forests and wildlife of state of Rio de Janeiro.
