“…While well‐represented species have been affected by habitat loss and land cover surrounding forest fragments, these effects could be exacerbated for threatened species when population sizes are reduced and/or ranges are restricted. There is therefore an urgent need for conservation measures to prevent conversion of remaining native habitats and, where appropriate and possible, to restore degraded habitats (Schüler & Bustamante, 2022). Further studies combining species‐level and trait‐based approaches are needed to examine species, ecological functions and ecosystem services at risk, and to inform effective conservation planning in human‐modified landscapes.…”

While harboring the bulk of the planet's biodiversity, tropical ecosystems have experienced intense land conversion for agriculture. Studies examining the impacts of land‐use change on tropical biodiversity have primarily focused on forest cover loss but have overlooked the ecological potential of habitats surrounding forest fragments to modulate biodiversity loss. We examined whether small‐mammal communities changed with the land cover surrounding forest fragments, and how functional traits affected responses to land cover. Small mammals were sampled in the Brazilian Cerrado using live‐trap transects. Three landscape types were identified according to the surroundings of the transects (within 750‐m‐radius buffers): forest‐ (≥50% forest cover), pasture‐, and crop‐dominated landscapes (<50% forest cover, with predominance of pastures or crops, respectively). We examined the composition of functional traits across landscape types and used abundance models to analyze the response of small‐mammal communities to land cover. From forest‐dominated to pasture‐ and crop‐dominated landscapes, the abundances and/or species richness of the largest, forest‐specialist, frugivorous/granivorous, and terrestrial species decreased. In forest‐dominated landscapes, abundances and species richness were slightly affected by land cover surrounding forest fragments. In pasture‐ and crop‐dominated landscapes which represent the less‐preserved landscapes, increased proportions of native forests, open formations, and, to some extent, pastures, supported the increased abundance of small mammals. Land cover surrounding forest fragments is critical for maintaining the diversity of species and functional traits within small‐mammal communities. Our results emphasize the need to maintain native vegetation in human‐modified landscapes to maintain biodiversity and ecological functions.

“…The freely available LULC dataset MapBiomas [35] collection 6.0 provides annual maps covering the 2002-2020 period, and has been considered a reference in recent studies conducted in the Brazilian territory, including the Amazon [47][48][49] and Cerrado [50][51][52] biomes. Following novel approaches, MapBiomas provides the annual LULC maps at the spatial resolution of 30 m where the automatic and pixel-by-pixel classifications of Landsat images are based on the machine learning algorithm Random Forest [53] implemented on Google Earth Engine [35].…”

Biomass burning (BB) emissions negatively impact the biosphere and human lives. Orbital remote sensing and modelling are used to estimate BB emissions on regional to global scales, but these estimates are subject to errors related to the parameters, data, and methods available. For example, emission factors (mass emitted by species during BB per mass of dry matter burned) are based on land use and land cover (LULC) classifications that vary considerably across products. In this work, we evaluate how BB emissions vary in the PREP-CHEM-SRC emission estimator tool (version 1.8.3) when it is run with original LULC data from MDC12Q1 (collection 5.1) and newer LULC data from MapBiomas (collection 6.0). We compare the results using both datasets in the Brazilian Amazon and Cerrado biomes during the 2002–2020 time series. A major reallocation of emissions occurs within Brazil when using the MapBiomas product, with emissions decreasing by 788 Gg (−1.91% year−1) in the Amazon and emissions increasing by 371 Gg (2.44% year−1) in the Cerrado. The differences identified are mostly associated with the better capture of the deforestation process in the Amazon and forest formations in Northern Cerrado with the MapBiomas product, as emissions in forest-related LULCs decreased by 5260 Gg in the Amazon biome and increased by 1676 Gg in the Cerrado biome. This is an important improvement to PREP-CHEM-SRC, which could be considered the tool to build South America’s official BB emission inventory and to provide a basis for setting emission reduction targets and assessing the effectiveness of mitigation strategies.

“…The Cerrado biome is considered one of the world’s biodiversity hotspots [ 14 ], and this region currently has the largest established agricultural area in the country, which led to the loss of 55% of the original altered area of native vegetation [ 15 ]. On the other hand, this region faces intense habitat loss [ 16 ], accounting for 26% of Brazilian emissions from land-use change [ 17 ] 10,688.73 km 2 yr −1 [ 18 ].…”

This study evaluated Carbon (C) storage in different compartments in eucalyptus stands and native Cerrado vegetation. To determine C above ground, an inventory was carried out in the areas where diameter at breast height (DBH), diameter at base height (Db), and total tree height (H) were measured. In the stands, the rigorous cubage was made by the direct method, and in the native vegetation, it was determined by the indirect method through an allometric equation. Roots were collected by direct method using circular monoliths to a depth of 60 cm and determined by the volume of the cylinder. Samples were collected up to 100 cm deep to estimate C stock in the soil. All samples collected directly had C determined using the CHNS elemental analyzer. Gas samples were collected using a manually closed chamber, and the gas concentration was determined by gas chromatography. The results indicate high C storage in the studied areas > 183.99 Mg ha−1, could contribute to CO2 mitigation > 674.17 Mg ha−1. In addition to low emissions (<1 kg ha−1 yr−1) for the three evaluated areas, with no statistical difference in relation to the Global Warming Potential. Concerning the native cerrado vegetation conversion, the “4-year-old eucalyptus stand” seemed to restore the original soil carbon stocks in the first-meter depth, regardless of some losses that might have occurred right after establishment. Conversely, a significant loss of carbon in the soil was observed due to the alternative setting, where similar natural land was converted into agriculture, mostly soybean, and then, years later, turned into the “6-year-old eucalyptus stand” (28.43 Mg ha−1). Under this study, these mixed series of C baselines in landscape transitions have reflected on unlike C dynamics outcomes, whereas at the bottom line, total C stocks were higher in the younger forest (4-year-old stand). Therefore, our finding indicates that we should be thoughtful regarding upscaling carbon emissions and sequestration from small-scale measurements to regional scales
