The carbon sink of southeastern Brazil seasonal forests is decreasing over time; in 2013, the became a source.
Seasonal floodplain forests are important ecosystems that attenuate floods and have high biodiversity. However, floodplains threatened by human activities, such as dam building, agricultural water use, climate change. Improving our understanding of the functioning can aid in their protection. Trees southeastern Brazil experience flooding for more than a month per year but also must endure very dry periods where groundwater level is several meters below surface. Species composition depends on...
Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such vary across world’s forests. By mapping life history traits for wide range species Americas, reveal considerable variation in expectancies from 10 centimeters diameter (ranging 1.3 to 3195 years) show that pace trees can be accurately classified into four demographic functional types. We found emergent patterns strength between temperature gradient....
Abstract Floodplains are one of the most threatened ecosystems. Even though vegetation composition in floodplain forests is expected to reflect variation groundwater levels and flood duration frequency, there little field data on inundation dynamics (e.g., variability frequency), especially for understudied seasonally dry tropics. This limits our understanding these ecosystems mechanisms that cause flooding. We, therefore, investigated six state Minas Gerais Brazil 1.5 years (two wet...
Abstract Large‐scale data compilation is increasing steadily in tropical forest research, but the lack of standardized methods for collection limits drawing inference from large datasets and cross‐biome analyses. Different inclusion minimum tree diameter threshold are among these varying factors. To tackle this issue, we evaluated how different approaches sampling affects our understanding diversity functioning vegetation types. We used a unique dataset 44 inventory plots (43.54 ha)...
This work reports the isolation of sesquiterpene lactone 15-deoxygoyazensolide from stems Minasia alpestris and evaluation its antimicrobial activity against following oral pathogens: Enterococcus faecalis, Streptococcus salivarius, sobrinus, mutans, mitis, sanguinis, Lactobacillus casei. Despite cytotoxicity genotoxicity other lactones furanoheliangolide-type, our results revealed that this compound exhibits low antibacterial evaluated pathogens; however, an interesting selectivity E....
Floodplain forests are unique ecosystems at the interface between rivers and terrestrial environments. They provide important ecosystem services, such as biodiversity conservation flood control. However, they also one of most threatened ecosystems. Vegetation composition in floodplain depends on regime, but there is a lack knowledge relation water level regime forest functioning for seasonally dry tropics. As result, it unclear how these will be impacted by climate change. In WatForFun...
Abstract Seasonally Dry Tropical Forests experience pronounced precipitation seasonality, intense solar radiation, and high temperatures, which often translate into levels of deciduousness during the dry season. In these environments, deciduous species coexist with some evergreen that are able to maintain their canopy leaves throughout To understand strategies behind this behavior, we analyzed leaf anatomical traits 13 individuals Sarcomphalus joazeiro both wet seasons in a seasonal forest....
Abstract Aims We aimed at disentangling the effects of spatial distance, current and past environmental dissimilarity, their combinations on tree community taxonomic phylogenetic turnover by addressing following questions: (i) Is related to indirect distance via dissimilarity? (ii) Does respond paleoclimate (Last Glacial Maximum Mid-Holocene)? Methods The study was carried out in 14 Atlantic rainforest sites Brazil (20.4 ha sampled) containing 615 species from 83 plant families. obtained...
Background The mass ratio hypothesis (functional dominance) and niche complementarity diversity) are two potential approaches for making the link between biodiversity biomass. It is yet unclear how biomass related in seasonally dry tropical forest (SDTF) communities where there a seasonal water limitation.Aims objective of this study was to quantify effects environmental filtering on ecosystem functioning, especially those above-ground biomass.Methods We estimated functional traits all...
Abstract Forest community dynamics is a topic of great interest in times when the global carbon budget widespread concern due to climate change. Among its effects, longer periods drought and liana proliferation, coupled with land use change, may endanger tropical forest sinks. Here, 10.3 ha sampling six Atlantic semideciduous forests, we investigated effects crown occupancy large‐stemmed lianas, as well their interactions soil, on dynamics. We expected that harsh environmental conditions...
Discrete thresholds of structural or functional decline a vegetation type are not readily apparent, as can slowly leading to transformations in its species composition and weakened altered functions. However, forest monitoring be used assess changes ecological functions community structure phylogenetic species. This study evaluated the existence temporal variations tree community, occurrence heterogeneity behavior variations, how this possible influences under aspect environmental by...
A new species of Pseudobombax (Bombacoideae, Malvaceae) is described from the Furados, Caatingas Domain, Brazil. The morphologically similar to simplicifolium but differs by obovate, elliptic, depressed obovate or orbicular leaflets, presence branched trichomes on terminal branches, leaf primordia, petioles, adaxial and abaxial surfaces pedicel, bracteoles, outer surface calyx, lepidote ovary, subglobose ovoid, spotted seeds.
