Urban green areas are essential for the quality of life people living in large cities. In Brazil, 84.7% population lives cities; however, studies assessing urban tree cover distribution and population's accessibility to such spaces scarce. We aim at areas’ Rio de Janeiro City, according places where live dominant economic classes each neighborhood. order do so, 123 public larger than 5,000 m² were selected study, as well city's network. It was mainly done analyze both vegetation...

As cidades concentram 80% da população brasileira, muitas vezes de forma inadequada causando grandes problemas. A arborização urbana, quando feito correta atenua alguns efeitos negativos como, poluição sonora, visual, atmosférica e hídrica. Os objetivos deste trabalho foram quantificar qualificar a vegetação urbana do município Socorro – SP, sugerindo formas mais adequadas ecológicas para propor uma as espécies que causam maiores danos ao calçamento fiação. Foram percorridas todas ruas...

Um dos principais passos para a conservação de florestas é o conhecimento da composição florística e estrutura, as relações destas com variáveis ambientais. Assim,realizou-se levantamento comunidade arbórea um fragmento floresta estacional semidecidual montana, situada no município Socorro, SP, bacia do Rio Mogi-Guaçu (22º32’S 46º34’W, altitude 750 m), objetivo conhecer sua estrutura florística, além das variações espaciais relacionadas às edáficas à borda fragmento. Para mesmo, foram...

We aim evaluate phytosanitary status each tree, potential popular uses and damages caused by trees infrastructure. Data collection was based on inventoring streets squares neighborhood. Trees were identified classified plant health, spinning damage, pavement origin social use. In total, we sampled 1,203 individuals belonging 88 32...

The state of Rio de Janeiro has been degraded mainly in lowlands, where protected areas harboring most remaining forests are located. present study aimed to assess the application compensatory measures (CM) restore vegetation Bosque da Barra Municipal Natural Park. We analyzed survival planted specimens by dividing area into six quadrants with approximately nove hectares each. For analysis, we used a frequency class method and assessed success rate per quadrant, 2,125 seedlings 73 native...

Abstract: This study investigated the current Leguminosae tree species composition in coastal forests over lithosoil soil or sandy plains eastern and central portion of Rio de Janeiro state, Brazil. A comparative between Atlantic Forest areas Southeast Region Brazil was conducted to evaluate influence environmental variables on floristic differentiation. total 34 selected from NeoTropTree platform these were basis for a similarity analysis. The Jaccard Similarity Index UPGMA method applied...

Abstract: Aim In this study, we determined whether Perlidae nymphs found in leaf litter were morphometrically distinct from those stony substrates. Methods Specimens collected Parque Nacional da Serra dos Órgãos, Teresópolis, Rio de Janeiro, Brazil. Each insect was measured for femora length, body wingpad head width, compound eye distance and mesothorax thickness. Data logarithmically transformed to avoid effects of allometric growth subjected a size-free discriminant analysis. Analysis...

Generally considered a sustainable economic activity, tourism can generate environmental deterioration due to lack of planning. In this case, the edge effect is utilized assess degree human interference in environment. Although Atlantic Forest known as hotspot because its high species richness and endemism, it also threatened biome. context anthropogenic pressure, our work assesses edge-interior gradient regenerating forest based on physical characteristics vegetation floristic composition,...

The Tijuca National Park is considered to be the world’s second largest urban forest, and was contemplated by first project for recuperation of degraded habitats in Brazil. As it located center Brazil’s second-largest city, Rio de Janeiro, also a popular attraction both tourists residents, includes features such as scenic lookouts, waterfalls, trails. In 2014, research program initiated evaluate anthropogenic impacts on diverse biological communities found vicinity waterfalls which visitors...

The Atlantic Forest and Cerrado are domains of Brazil. We should pay more attention to the lesser assessed points in these biomes, as well their rocky outcrops. These sites under great anthropogenic pressure due mineral exploitation present. This results environmental degradation loss species that have not yet been studied. In present study we aimed characterize structure composition a outcrop order provide aids for creation protected areas on adoption management techniques degraded by...
