Abstract The Brazilian Cerrado is a global biodiversity hotspot with notoriously high rates of native vegetation suppression and wildfires over the past three decades. As result, climate change can already be detected at both local regional scales. In this study, we used different approaches based on independent datasets to investigate possible changes in daytime nighttime temperature air humidity between peak dry season beginning rainy Cerrado. Additionally, evaluated tendency dew point...
Although many of the current hypotheses to explain origin and distribution Amazon biodiversity has been based directly or indirectly on geological data, reconstruction history region is still inadequate analyze its relationship with biodiversity. This work main goal characterize sedimentary successions formed in Brazilian Neogene-Quaternary discussing evolution depositional systems through time analyzing their controlling mechanisms order fill up this gap. Radar image interpretation,...
Following an intense occupation process that was initiated in the 1960s, deforestation rates Brazilian Amazon have decreased significantly since 2004, stabilizing around 6000 km(2) yr(-1) last 5 years. A convergence of conditions contributed to this, including creation protected areas, use effective monitoring systems, and credit restriction mechanisms. Nevertheless, other threats remain, rapidly expanding global markets for agricultural commodities, large-scale transportation energy...
Climate change has been identified as the primary threat to integrity and functioning of ecosystems in this century, although there is still much uncertainty about its effects degree vulnerability for different threat. Here we propose a new methodological approach capable measuring mapping resilience terrestrial at large scales based on their climatic niche. To do this, used high spatial resolution remote sensing data ecological niche modeling techniques calculate spatialize three stable...
The Solimões Formation (Eocene-Pliocene) is a well-known geological unit due to the great diversity of crocodylian species. Here we describe new species Melanosuchus, M. latrubessei sp. nov., from Talismã locality, state Amazonas, Upper Miocene (Solimões Basin, Brazil). A phylogenetic inference focused on Caimaninae provided and different evolutionary scenarios involving this are discussed. In addition, quantitative morphology studies carried out comments regarding paleoecology aspects made....
Cocoa is a plant with origins in northwestern South America high relevance the global economy. Evidence indicates that cocoa sensitive to dry climate, under which crop production reduced. Projections for future climate change scenarios suggest warmer and drier Amazon basin. In this paper, we quantify potential effects due its edaphoclimatic suitability changes Brazilian biome account regional differences planning occupation territories. We modeled of cocoa's geographical distribution using...
Terrestrial biomes are the main reservoirs of biodiversity and CO2 on planet. In South America, they play a crucial role in climate regulation conservation. Despite scientific advances recent efforts, there is still no detailed analysis trends surface air temperature precipitation changes until end 21st century magnitude change for America’s terrestrial biomes. this study, we used annual mean cumulative variables provided by WorldClim (version 2.1) from an ensemble five Global Circulation...
The focus of this work is on small municipalities (population below 50 thousand inhabitants) that cover around 87% the territory Brazilian Legal Amazon (BLA). Based a comprehensive integrated analysis approach using three components hazard (climate extremes from CMIP6 future scenarios), exposure (directly affected population), and vulnerability (subdimensions susceptibility coping/adaptive capacity by multidimensional indicators), latter two current datasets provided official Census IBGE...
Recovered from Quaternary deposits in Carneiro Cave (Serra da Mesa, Brazil), associated with a clayey-sandy sedimentary influx older than the overlying calcite layer, which has been dated to 182.8 ± 1.2 ka, new extinct species of Rhinophylla is described based on proximal radio fragment. This discovery represents one three oldest occurrences Chiroptera exposed stratigraphic profile. The fossil record consists 1,117 bone fragments, distributed across Pleistocene and Holocene packages....
A paleomegafauna site from central Amazonia with exceptional preservation of mastodons and ground sloths allows for the first time a precise age control based on 14 C analysis, which, together sedimentological δ 13 isotope data, provided basis to discuss habitat evolution within context climate change during past 15,000 yr. The fossil-bearing deposits, trapped depression in Paleozoic basement, record three episodes sedimentation formed floodplains, an intermediate unit recording catastrophic...
The lower Miocene Pirabas Formation in the North of Brazil was deposited under influence proto-Amazon River and is characterized by large changes ecological niches from early onwards. To evaluate these changes, elasmobranch fauna fully marine, carbonate-rich beds investigated. A diverse with 24 taxa sharks rays identified dominant groups being carcharhiniforms myliobatiforms. This faunal composition similar to other assemblages proto-Carribbean bioprovince. However, has unique features...
Anthropogenic transformations, which have become intensified by land use and cover changes industrialization, contributed to increased anthropogenic pressure on biodiversity. These disturbances contribute toward fragmentating habitats at different scales putting species risk, in addition compromising the main biogeochemical cycles. To better understand spatiotemporal dynamics of Brazilian biomes, this study sought develop a composite index identify analyze degree distribution...
A SOCIEDADE brasileira recebe, anualmente, a estimativa de perda floresta na Amazônia por meio da taxa desflorestamento divulgada pelo Inpe, qual, em 2004, foi aproximadamente 26.130 km² . O que não se conhece é o quanto recursos naturais perde cada quilômetro quadrado destruída. Neste trabalho, apresentamos números concretos desta perda, baseados estudos recentes sobre densidade plantas e alguns grupos animais Amazônia. Com base nisso, defendemos idéia há necessidade ampliar região que,...
Abstract Earthen mounds with archaeological artifacts have been well known in Marajó Island since the 19th century. Their documented dimensions are impressive, e.g., up to 20 m high, and areas as large 90 ha. The mounds, locally tesos, impose a significant relief on very low‐lying landscape of this region, which averages 4 6m above present sea level. These features traditionally interpreted artificial constructions Marajoara culture, designed for defense, cemetery purposes, or escape from...
What controls the formation of patchy substrates white sand vegetation in Amazonian lowlands is still unclear. This research integrated geological history and plant inventories a patch confined to one large fan-shaped sandy substrate northern Amazonia, which related megafan environment. We examined floristic patterns determine whether abundant species are more often generalists than rarer one, by comparing environments older basement rocks. also investigated pattern accumulation as function...
ABSTRACT Assessing patterns of abundance and distribution Amazonian species is still an overwhelming task that requires integration multiple disciplines. This work based on background information gathered from previous reconstructions the geological history lower Amazon drainage basin, in order to analyse biodiversity within context landscape transformation. A highly dynamic scenario depicted for this area during Plio‐Pleistocene Holocene, which consisted a large palaeovalley formed as...
