ECOTURISMO E OS IMPACTOS AMBIENTAIS NO PARQUE ESTADUAL MATA DO PAU-FERRO, AREIA, PARAÍBA

O presente trabalho tem como objetivo analisar a prática do ecoturismo no Parque Estadual Mata do Pau-Ferro, localizado no município de Areia, microrregião do Brejo Paraibano, como estratégia de uso sustentável da Unidade de Conservação. A metodologia utilizada foi um levantamento bibliográfico dos principais autores que abordam a temática em questão e visitação in loco, onde aplicaram-se questionários com pessoas que trabalham de forma direta ou indireta com a atividade turística no Parque Estadual. Tendo em vista que no local são frequentes as práticas voltadas para o turismo ecológico por meio das trilhas, o que possibilita o contato com ambientes naturais e proporciona uma série de atividades turísticas baseadas na relação sustentável com a natureza, observou-se que o uso intenso do Parque Estadual tem impactado a gestão sustentável devido ao alto grau de visitações. Há necessidade de implantação de medidas fiscais eficientes através da elaboração e efetivação do plano de manejo com o objetivo de compatibilizar a atividade ecoturística com a capacidade de carga do ambiente, promovendo assim sua conservação

Correlation between physiological and agronomic characteristics of tomatoes

O presente trabalho objetivou analisar a correlação entre variáveis de crescimentoe caracteres agronômicos de tomateiro. O delineamento experimental foi de blocos ao acaso, com oito repetições. Os tratamentos foram compostos por plantas de tomateiro enxertadas e não enxertadas. Aos 112 dias após o transplante as plantas foram coletadas e separadas em órgãos (frutos, folhas, caule e raiz) para ser avaliado o número de folhas, número de frutos, área foliar, clorofila, eficiência na conversão de energia solar, massa seca de frutos, produtividade comercial, pH, sólidos solúveis totais, carotenóides e compostos fenólicos. Plantas enxertadas apresentaram maiores teores de clorofila. Para as variáveis referentes às correlações, foram encontrados fortes correlações entre a área foliar, o teor de clorofila e a massa seca de frutos e total. Enquanto que, os teores de carotenóides e fenóis totais se correlacionaram positivamente com a área foliar e o teor de clorofila.The present work aimed to analyze the correlation between growth variables and agronomic traits of tomato. The experimental design was randomized blocks, with eight replications. The treatments consisted of grafted and non-grafted tomato plants. At 112 days after transplantation, the plants were collected and separated into organs (fruits, leaves, stem and root) to be evaluated the number of leaves, number of fruits, leaf area, chlorophyll, efficiency in the conversion of solar energy, dry mass of fruits, commercial productivity, pH, total soluble solids, carotenoids and phenolic compounds. Grafted plants showed higher levels of chlorophyll. For the variables related to the correlations, strong correlations were found between the leaf area, the chlorophyll content and the dry mass of fruits and total. While, the levels of carotenoids and total phenols correlated positively with the leaf area and chlorophyll content.Facultad de Ciencias Agrarias y Forestale

Neurological changes post-covid-19 infection: signs and symptoms that remain

Since 2019, humanity has faced the pandemic outbreak of COVID-19 disease, caused by the new coronavirus, SARS-CoV-2. Respiratory symptoms of the disease were investigated and monitored worldwide, however, the nervous system lesions induced by COVID-19 did not receive as much attention. The aim of this study was to highlight the neurological alterations after infection of the new coronavirus, thus highlighting the symptoms that remained after Infection by SARS-CoV-2. The review shows relevant data on drugs and SARS-CoV-2, neurological alterations, complications and adverse effects related to COVID-19. At the time of writing this article, in mid-2022, SARS-CoV-2 is still spreading in several countries and infecting the population, leaving many people with temporary or permanent sequelae because of COVID-19

Estudos Artísticos

A arte inclui no seu sistema os mesmos processos que reproduzem o poder ou que renovam as suas retóricas através de astúcias de resistência. Criou-se me tempos a proposta radical de uma arte emancipada, independente de referencialidade para além dos valores plásticos. Esta radicalidade escondia afinal um conformismo otimista e modernista: a arte “abstrata” era conservadora, decorativa, e não incomodava afinal ninguém. Aqui se mostra a oportunidade deste desafio, da chamada de artigos que esta Revista Croma 14 convocou: o desafio é entrar no caleidoscópio das ilusões sem perder o norte, sem abdicar do sentido último da cultura, que é mais humanidade, mais inteira, mais consciente.info:eu-repo/semantics/publishedVersio

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

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
