Article
Full-text available
Recent severe droughts, extreme floods, and increasing differences between seasonal high and low flows on the Amazon River may represent a twenty-first-century increase in the amplitude of the hydrologic cycle over the Amazon Basin. These precipitation and streamflow changes may have arisen from natural ocean–atmospheric variability, deforestation...
Article
Subsets of annual and sub-annual tree-ring chronologies are used to reconstruct seasonal precipitation totals in northern California. The specific seasons selected for reconstruction are based on the strongest monthly precipitation signals recorded in the tree-ring data. Earlywood width of gray pine is best correlated with Oct-Dec precipitation at...
Article
During the last two decades the tropical Amazon forests have been impacted by frequent and severe droughts. However, little is known about the impacts of these extreme events on wood traits. In this study, we quantified long- and short-term impacts on growth and wood density response and resilience strategies under extreme droughts, analyzing th...
Article
The analysis of climate variability and development of reconstructions based on tree-ring characteristics in tropical forests have been increasing in recent decades. In the Amazon region, ring width and stable isotope long-term chronologies have been used for climatic studies, however little is known about the potentiality of wood traits such as de...
Conference Paper
Changes in rainfall trends in Amazonia are being observed in ecent decades, possibly due to the amplification of the hydrological cycle over the region, resulting in an increase in climatic extremes. The low quantity and quality of climate data in Amazonia makes paleoclimate records essential for understanding the long-term variability and trend of...
Article
Full-text available
Brazil stands out worldwide for planting homogeneous forests, mainly pine and eucalyptus. Forestry production is of great importance for the country’s economy, being also a reference in sustainability, competitiveness and innovation. Of the 10 million hectares of planted trees, 76.3% is composed of the genus Eucalyptus, which makes Brazil one of th...
Article
Full-text available
Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obta...
Article
A análise da fragmentação de hábitats auxilia na eficácia de ações que evitem a perda significativa de florestas conservadas. Os municípios integrantes e contíguos à bacia hidrográfica do Rio Tijucas, em Santa Catarina, possuem bons remanescentes florestais em estádios preservados, e essa região conta ainda com a presença da REBio da Canela Preta,...
Article
Full-text available
Rainfall and river levels in the Amazon are associated with significant precipitation anomalies of opposite sign in temperate North and South America, which is the dominant mode of precipitation variability in the Americas that often arises during extremes of the El Niño/Southern Oscillation (ENSO). This co-variability of precipitation extremes acr...
Article
Full-text available
Instrumental observations indicate that Amazon precipitation and streamflow extremes have increased during the last 40‐years, possibly due to anthropogenic changes and natural variability. How unprecedented these changes might be is difficult to determine because some paleoclimatic, instrumental, and climate model simulations suggest that Amazonian...
Article
A Cedrela odorata tree ring width chronology spanning from 1786 to 2016 was developed in the quasi-equatorial eastern Amazon Basin. Annual calendar dates were assigned using dendrochronological techniques at the Federal University of Lavras, Brazil. Due to its strategic location at the edge of the Equator (approximately 0°57′S), an independent conf...
Article
Full-text available
The Atlantic Forest is one of the largest and most biodiverse rainforests of South America but anthropo- genic activities are drastically changing these landscapes. The invasion of alien or exotic species is one of the great- est threats to biodiversity. There are few studies of inva- sive species in tropical Brazilian ecosystems. This research exa...
Presentation
Record rainfall totals have recently been recorded over the Amazon Basin and may be part of an amplified cycle of wet to dry season precipitation and streamflow. Just how unprecedented these recent hydroclimatic changes might be in the context of natural climate variability over the Amazon is difficult to determine from the short, sparse, and often...
Article
Full-text available
The Amazon basin is a global center of hydroclimatic variability and biodiversity, but there are only eight instrumental rainfall stations with continuous records longer than 80 years in the entire basin, an area nearly the size of the coterminous US. The first long moisture-sensitive tree-ring chronology has been developed in the eastern equatoria...
Article
Dendrochronology is a valuable tool to understanding climate-growth and growth-age relationships of native tree species from tropical forests. The information obtained from growth rings can elucidate climate responses of tree-growth under the ongoing environmental changes and support the development of sustainable forest management strategies based...
Article
The presence of distinct growth rings in a large number of tropical tree species has allowed a range of studies involving the growth history during the life span of the tree. This work aimed to examine the presence of tree rings and study growth patterns of tree species from five seasonally dry tropical forest fragments. Wood cores were extracted u...
Article
The São Francisco River basin is one of the most drought-prone regions of Brazil. Seasonally dry tropical forests (SDTF) are widely distributed in the basin and we developed a short chronology of Cedrela fissilis annual ring widths from SDTF fragments based on 89 cores from 44 trees dating from 1961 to 2015. The average correlation among all radii...
Article
Nectandra is one of the most representative genera of Lauraceae in the subtropical Atlantic Forest of Brazil. The objective of this work was to study the dendrochronological potential of Nectandra oppositifolia Nees and Mart. from two sites in Santa Catarina State in southern Brazil. A tree-ring chronology of 34 trees was developed. The time span r...
Article
The predominance of secondary forest-species in Brazilian subtropical forests highlights the importance of understanding the ecology of these taxa, and dendrochronology provides valuable information about the growth and climate response of tree species. The wide distribution of Alchornea triplinervia (Spreng.) Mull. Arg. (Euphorbiaceae), and the pr...
Conference Paper
O padrão de crescimento das plantas é determinado pela interação entre condições ambientais e endógenas. Espécies arbóreas, por terem maior ciclo de vida, ajustam seus padrões de crescimento a fim de elevar a eficiência no uso de recursos. Essas complexas relações podem ser compreendidas em condições de campo utilizando gradientes altitudinais, ond...

Thesis
Full-text available
O Bioma Mata Atlântica caracteriza-se por apresentar grande biodiversidade mas, em contrapartida, as suas florestas sofrem as consequências da fragmentação de habitats, tornando-se empobrecidas e estruturalmente simplificadas. O pouco conhecimento acerca da dinâmica e dos processos sucessionais limita o uso dos recursos nativos e, neste contexto, a...
Article
Ischemia is a transitory or permanent reduction of blood flow that may provoke an excessive release of glutamate. In that condition, increased reactive oxygen species generation and/or decreased cerebral antioxidant capacity may induce cell death. Antioxidant enzymes and thiols play an important role in the cellular defenses against oxidative stres...
Article
This study investigated the cellular signaling pathways involved in the acute antidepressant-like action of memantine in the forced swimming test (FST) in mice. The immobility time in the FST was reduced by memantine (3-10 mg/kg, i.p.). The anti-immobility effect of memantine (3 mg/kg, i.p.) was prevented by pretreatment with H-89 (1 microg/site, i...

Question
I need to measure vessel area or vessel diameter of the earlywood in the radii of our samples and I need a good software to do that. As we have windendro at our lab I was wondering if it does that?
