Summary: Land-use changes in the Atlantic Forest of Brazil have led to a decline in ecological functions performed by mammals, with vulnerable functions concentrated in large forest remnants and persistent functions prevalent in human-modified landscapes. This erosion of ecological functions compromises the biodiversity persistence in the Atlantic Forest.

Summary: This study investigates the impact of clandestine and regular road networks on Amazon forest deforestation and uses a time series analysis to predict deforestation trends over the next three decades. The results suggest that deforestation will continue to intensify, albeit with decreasing rates of forest loss over a ten-year period.

Summary: The study evaluated the effects of increased temperatures on seed germination success in the soil seed bank of secondary forests in Central Amazonia. Results showed that temperature increase affects germination and seedling density, and some species have specific sensitivities to temperature. The study suggests that natural regeneration in the region may be significantly impacted by global warming, potentially leading to changes in floristic composition.

Summary: Extreme precipitation and drought events are expected to increase in frequency and intensity in the Amazon rainforest. This study found that the forest has resistance and resilience to drought, but previous climatic events have lasting effects on the forest's response to drought.

Summary: Despite being the least profitable factor, forest conversion is expected to intensify in the future, especially in the inner regions of the Brazilian Legal Amazon (BLA). Specific geographic regions in BLA exhibit significant heterogeneity and are associated with different phases of forest transition across the analyzed period.

Summary: Selective logging and the construction of logging roads can have a significant impact on the occupancy and detection of terrestrial mammals in tropical forests. This study in Guyana found that properly managed logging roads can actually have a positive effect on mammal occurrence within logged forests. However, the distance to human settlements can also influence the presence of certain mammal species.

Summary: Forest growth models serve as valuable support tools for forest recovery assessment and management, providing diagnostic or prognostic information. The diffusive-logistic growth model is applied in this study to predict forest recovery in Brazilian Atlantic rainforest preservation areas. The results reveal that forest recovery could take several decades to stabilize without negative interventions, and the model presented can aid in decision-making and policy formulation for forest recovery.

Summary: Human-induced wildfires in tropical forests are increasing, causing decreases in seed rain and impacting biodiversity. This study in the Atlantic Forest remnants in Bahia, Brazil, found that fire and fire-created edges did not significantly influence seed rain, but there was a lower abundance of animal-dispersed seeds in burnt areas. Seed abundance was lower, and seeds were smaller and lighter in burnt areas compared to unburnt areas, posing challenges for natural regeneration. Seed rain was positively correlated with tree density, highlighting the differences in community composition between burnt and unburnt areas.

Summary: The two-striped forest-pitviper, represented by two subspecies, is a rare arboreal snake mainly found in the Amazon and Atlantic Forest regions. While encounters with this snake are rare, in some areas it can cause a significant proportion of snakebite envenomations.

Summary: Terrestrial isopods have developed various behavioral and morphological adaptations to avoid terrestrial predators, including tonic immobility, conglobation, and clinging to the ground. However, most of these strategies have not been studied.

Summary: Annual stem CO2 efflux increases with stem wood production rates and are inhibited by daily moisture stress in tropical forests. Fast-growing trees have higher carbon use efficiencies, and daytime stem CO2 efflux decreases during periods of high sap flow and transpiration. These findings suggest that diurnal dynamics of stem water status influence growth processes and respiratory metabolism.

Summary: This study examined the presence of Leptospira antibodies in two species of free-ranging tamarins and found that a high percentage of animals were reactive for at least one serogroup, suggesting they could serve as reservoirs for pathogenic Leptospira serogroups. No significant differences were found in seropositivity frequencies among categories within assessed variables. Further studies testing for active infection are needed to evaluate potential transmission risks to humans given increasing human-wildlife contact.

Summary: This study evaluated the wood quality of Hymenaea courbaril branches and compared it with trunk wood. The results showed that branch wood had smaller fiber dimensions, higher microfibril angle, and lower parallel compressive strength compared to trunk wood, but the basic density was similar. Branch wood is suitable for the production of high-value products such as furniture, decorative objects, floors, and utensils.

Summary: This study focused on the biological and distributional aspects of deep-sea giant isopods Bathynomus giganteus and Bathynomus miyarei, with depth being the most important environmental variable influencing their distribution. Bathynomus giganteus were found at depths between 600m and 1,000m, while B. miyarei densities were higher at shallower depths of 400m to 600m. The sexual maturity and longevity of both species were also examined, with B. giganteus assessed as Least Concern and B. miyarei categorized as Data Deficient in terms of extinction risk assessment.
