ANÁLISE DO USO E COBERTURA DA TERRA NA BACIA HIDROGRÁFICA DO RIO APEÚ, NORDESTE PARAENSE, ENTRE OS ANOS DE 1999 E 2014

A bacia hidrográfica do rio Apeú, localiza-se na mesorregião do nordeste paraense e abrange a superfície dos municípios de Castanhal, Inhangapí e Santa Izabel do Pará, apresenta-se como uma área importante para observação dos processos de alteração da paisagem, pois passou por intensas interferências antrópicas. Este trabalho teve por objetivo fazer uma análise das mudanças do uso e cobertura da terra na bacia hidrográfica do rio Apeú entre os anos de 1999 e 2014, visando oferecer subsídios para o planejamento e gestão ambiental dessa bacia. Para tal, foi realizado um estudo multitemporal utilizando imagens de satélite Landsat/TM 5, órbita 223, ponto 061, bandas 3, 4 e 5, referente aoano de 1999, e a imagem de satélite Landsat/OLI-TIRS 8, órbita 223, ponto 061, bandas 3, 5 e 6, referente ao ano de 2014, a base cartográfica utilizada foi do IBGE na escala de 1:100.000 e os softwares ArcGIS 10.1 e Envi 5.1. Levando em consideração as principais mudanças de uso e cobertura da terra na bacia hidrográfica do rio Apeú foi realizada umaclassificação supervisionada, sendo adotadas as seguintes classes: área de mineração, área urbana, pastagem e vegetação. Os resultados mostraram que a paisagem da bacia sofreu grandes mudanças nesse período analisado, houve o aumento na classe de pastagem e área urbana, já a classe vegetação sofreu uma grande redução. Este estudo espera contribuir com dados de uso e cobertura da terra na construção de instrumentos de planejamento ambiental e garantir melhor gerenciamento dos recursos naturais

Fluxos de CO2 em Plantio de Palma de Óleo no Leste da Amazônia

Terrestrial ecosystems are important for the CO2 exchange between surface and atmosphere. This work presents the atmospheric conditions and CO2 measurements in interspecific hybrid of oil palm in eastern Amazonia, during El Niño year. The experiment was carried out in Moju-Pará, where a micrometeorological tower was installed to obtain meteorological and CO2 data during the period from january to december 2015. The diurnal averages of CO2 uptake peaked at noon, with 22.3 (± 0.98) mol m-2 s-1 in the wet season and 21.0 (± 0.47) mol m-2 s-1 in the dry season. There was little variation in nocturnal averages of CO2 emission, about 5 (± 0.20) mol m-2 s-1, in both wet and dry seasons. The diurnal averages of CO2 concentration were lower and nocturnal averages were higher. Generally, the daily CO2 exchange cycle presented a difference between the wet and dry season. These results contribute to a better understanding of the temporal trend of CO2 fluxes in agricultural crop during drought year in eastern Amazonia, generating new pieces of information about the interaction between oil palm and atmosphere. © 2018, Sociedade Brasileira de Meteorologia.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

IMPACTO DE VARIÁVEIS CONGNITIVAS E CONTEXTUAIS SOBRE O SUCESSO ACADÊMICO E O BEM ESTAR NA UNIVERSIDADE – QUE FAZER? QUE DEIXAR DE FAZER?

Este estudo parte de uma investigação longitudinal (2019-2022) mais ampla, vinculada ao Grupo Multidisciplinar de Pesquisa em Educação, Psicopedagogia e Psicologia Escolar, UFAM/CNPq, PROCAD/AMAZÔNIA-PPGEUFAM/UFPA/UFMT, Processo CAPES 8881.314288/2019-0, articula-se metodológica e teoricamente com interfaces entre a psicologia escolar, psicologia educacional, pedagogia do ensino superior e educação escolar. Atua no sentido de entender os efeitos de variáveis cognitivas e contextuais sobre o sucesso acadêmico e o bem estar na universidade. A metodologia para coleta de dados é a aplicação de caderno de instrumentos próprios com apoio do Googleodocs, a amostra atual é de n=1112 estudantes de diferentes países (Brasil, México, República Dominicana, Bolívia, Moçambique, Angola, Venezuela, Colômbia, Espanha e Portugal), do sexo masculino e feminino, idade entre 18 e 54 anos e de 51 universidades públicas e privadas que colaboram com a iniciativa. Os dados são analisados com auxílio do Excel e SPSS, de acordo com os interesses dos pesquisadores e objetivos da investigação. Os resultados atuais demonstram a importância da pesquisa sobre os temas abordados pela iniciativa considerando o impacto das variáveis estudadas sobre o rendimento acadêmico e bom estar tanto de estudantes como de docentes e técnicos no ensino superior. Foram identificadas diferenças de países, renda, etnia, gênero e renda. No caso dos docentes e técnicos verificamos evidências da exaustão feminina. Os resultados podem apoiar a administração geral e coordenação educativa e psicopedagógica universitária em sentido amplo, visando a melhoria dos indicadores de sucesso acadêmico e bem estar, por meio da proposição de novas políticas e gestão da educação superior.

The Genome of Anopheles darlingi, the main neotropical malaria vector

Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and females collected in the Brazilian Amazon. A total of 10 481 predicted protein-coding genes were annotated, 72% of which have their closest counterpart in Anopheles gambiae and 21% have highest similarity with other mosquito species. In spite of a long period of divergent evolution, conserved gene synteny was observed between A. darlingi and A. gambiae. More than 10 million single nucleotide polymorphisms and short indels with potential use as genetic markers were identified. Transposable elements correspond to 2.3% of the A. darlingi genome. Genes associated with hematophagy, immunity and insecticide resistance, directly involved in vectorhuman and vectorparasite interactions, were identified and discussed. This study represents the first effort to sequence the genome of a neotropical malaria vector, and opens a new window through which we can contemplate the evolutionary history of anopheline mosquitoes. It also provides valuable information that may lead to novel strategies to reduce malaria transmission on the South American continent.
