DIAGNÓSTICO QUALI-QUANTITATIVO DA ARBORIZAÇÃO URBANA DO BAIRRO PANTANAL DO MUNICÍPIO DE MACAPÁ-AP

Este trabalho teve como objetivo realizar um inventário quali-quantitativo da arborização urbana do bairro Pantanal, Macapá, AP. Portanto, foram avaliados as condições arbóreas através dos parâmetros: porte arbóreo das espécies identificadas, disposição do fuste, presença de fios elétricos sob as árvores e calçamento adequada, por meio de índices de diversidade de Shannom e Simpsom foram avaliados a riqueza de espécies, e foi delimitada a área das copas e a cobertura arbórea por rua. Foram identificados 144 indivíduos arbóreo, sendo 17 espécies, pertencentes a 9 famílias botânicas. As espécies Mangifera indica L. e Cocos nucifera L. totalizaram 59% de indivíduos. A maioria dos indivíduos apresentam altura de até 5 m. Foi observado que 67,36 % dos indivíduos apresentaram fuste reto. Quanto que 68,06% estão com calçamento inadequado. Constatou-se que 77,78% da população vegetal encontra-se livre de fiação elétrica. O índice de Shannon (1,94) foi considerado baixo e o índice Simpson (0,79) indicou alta dominância de uma única espécie. A arborização em relação as copas foram insuficientes para proporcionar conforto térmico e sombreamento adequado. Conclui-se que arborização do bairro Pantanal encontra-se no estado juvenil, a maioria da vegetação no bairro é de espécies exóticas, a maioria das árvores não apresentam problemas fisionômicos.    Palavras-chave: levantamento florístico; condições urbanas; dominância; frequência.   Quali-quantitative diagnosis of urban arborization in the Pantanal Neighborhood of the municipality of Macapá, Amapá, Brazil   ABSTRACT: This study aimed to conduct a qualitative and quantitative inventory of urban afforestation in the Pantanal neighborhood, Macapá, AP. Therefore, the tree conditions were evaluated through the parameters: tree size of the identified species, stem arrangement, presence of electrical wires under the trees and adequate pavement, using Shannom and Simpsom diversity indexes, the species richness was evaluated, and the crown area and the tree cover per street were delimited. 144 tree species were identified, 17 species, belonging to 9 botanical families. The species Mangifera indica L. and Cocos nucifera L. totaled 59% of individuals. Most individuals are up to 5 m tall. It was observed that 67.36% of the individuals had a straight shaft. As 68.06% are with inadequate paving. It was found that 77.78% of the plant population is free of electrical wiring. The Shannon index (1.94) was considered low and the Simpson index (0.79) indicated high dominance of a single species. The afforestation in relation to the crowns was insufficient to provide thermal comfort and adequate shading. It is concluded that the afforestation of the Pantanal neighborhood is in the juvenile state, most of the vegetation in the neighborhood is of exotic species, most of the trees do not present physiognomic problems.

Global assessment of marine plastic exposure risk for oceanic birds

Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and migration. However, the spatial overlap between petrels and plastics is poorly understood. Here we combine marine plastic density estimates with individual movement data for 7137 birds of 77 petrel species to estimate relative exposure risk. We identify high exposure risk areas in the Mediterranean and Black seas, and the northeast Pacific, northwest Pacific, South Atlantic and southwest Indian oceans. Plastic exposure risk varies greatly among species and populations, and between breeding and non-breeding seasons. Exposure risk is disproportionately high for Threatened species. Outside the Mediterranean and Black seas, exposure risk is highest in the high seas and Exclusive Economic Zones (EEZs) of the USA, Japan, and the UK. Birds generally had higher plastic exposure risk outside the EEZ of the country where they breed. We identify conservation and research priorities, and highlight that international collaboration is key to addressing the impacts of marine plastic on wide-ranging species

REGENERAÇÃO NATURAL DE Mora paraensis (Ducke) Ducke EM UMA FLORESTA DE VÁRZEA

Este estudo teve como objetivo analisar a regeneração natural de Mora paraensis em uma floresta de várzea no município de Macapá-AP. Buscou-se responder questionamentos a respeito do padrão de distribuição espacial da população e distribuição espacial em relação a planta-mãe. Foi demarcada uma área de 1 ha, selecionando 10 matrizes com diâmetro à altura do peito (DAP) ≥10 cm. Estabeleceu-se quatro transectos em cada uma dessas matrizes, orientados pelos pontos cardeais. Para avaliar se existe diferença entre o número de indivíduos entre os pontos cardeais foi utilizado o teste de Kruskal-Wallis. Nos transectos, realizou-se um censo dos regenerantes, sendo mensurado o diâmetro à altura do solo (DAS <3 cm) e a altura. Foram registrados 2.606 regenerantes, as subparcelas que apresentaram maior densidade de indivíduos estavam próximas da planta-mãe, a distribuição espacial dos regenerantes foi agrupada, e sua estrutura em classes de DAS e altura retrataram crescimento nas primeiras classes. Não houve diferença significativa entre o número de indivíduos por transecto. Os indivíduos regenerantes de M. paraensis apresentaram padrão de distribuição agregado. A espécie possui abundância de regenerantes, distribuídos entre os pontos cardeais e que tendem a se concentrar próximos à planta-mãe.

We sought to answer questions about the pattern of spatial distribution of the population and spatial distribution in relation to the mother plant. An area of ​​1 ha was demarcated, defined 10 matrices with diameter at breast height (DBH) ≥10 cm. Four transects were established in each of these matrices, oriented by cardinal points. To assess whether there is a difference between the number of comparisons between the cardinal points, the Kruskal-Wallis test was used. In the transects, a census of the regenerants was carried out, measuring the diameter at ground height (DAS <3 cm) and height. A total of 2,606 regenerants were registered, the subplots that overloud density were available in the mother plant, the spatial distribution of the regenerants was grouped, and their structure in DAS and height depicted on the first classes. There was no significant difference between the number of desired per transect. Present regenerants of M. paraensis aggregate of aggregate distribution. The area has an abundance of regenerants, distributed among the cardinal points and which tend to concentrate on the mother plant. Keywords: Amazon; forest ecology; Morisita index; pracuúba
