TL;DR: It is found that mammal communities from highly fragmented sites have lower species richness, species diversity, functional diversity and higher dominance when compared with sites in partially fragmented and continuous forest.

TL;DR: Evaluating occupancy trends for 511 populations of terrestrial mammals and birds, representing 244 species from 15 tropical forest protected areas on three continents, finds that occupancy declined in 22, increased in 17%, and exhibited no change in 22% of populations during the last 3–8 years, while 39% of population were detected too infrequently to assess occupancy changes.

TL;DR: In this paper, a pan-tropical model was proposed to predict plot-level forest structure properties and biomass from only the largest trees, which can be used to generate accurate field estimates of tropical forest carbon stocks to support the calibration and validation of current and forthcoming space missions.

TL;DR: In this paper, the authors used camera traps to study mammals in Peperpot Nature Park (PNP), a secondary forest located 5 km from the capital of Suriname, and compared it to the large Central Surinames Nature Reserve (CSNR), finding fewer species in PNP (20 compared to CSNR (30).
