Desmatamento, degradação e violência no “Mosaico Gurupi” – A região mais ameaçada da Amazônia

Geographic range extension of Rapatea paludosa Aubl. (Rapateaceae) to Maranhão state, northeastern Brazil

“…The new records place R. paludosa in the Amazon Forest of Maranhão, one of the most endangered of this biome in Brazil, as only 25% of the original forest persists in that state (Celentano et al 2017(Celentano et al , 2018. Historically, deforestation accelerated in the 1960s with the opening of highways and incentives to develop agriculture on public lands.…”

“…Historically, deforestation accelerated in the 1960s with the opening of highways and incentives to develop agriculture on public lands. In the 1980s, the construction of the Carajás-São Luís railroad and iron, steel, and pig iron plants led to intense devastation of the Amazon Forest in the state (Almeida and Vieira 2010;Celentano et al 2017Celentano et al , 2018.…”

“…Adjacent to the Terra Firme Forest (domain of the Amazon Forest) and Sete Irmãos farm is Sítio José Pedro, another private area of circa 200 ha, with a fragment of Gallery Forest. Both are part of the Belém Endemism Center, a poorly studied, species-rich area under serious threat due to deforestation and other anthropic activities (Almeida and Vieira 2010;Celentano et al 2017Celentano et al , 2018.…”

Found in Brazil again! Expanding the distribution of Maxillaria aureoglobula Christenson (Orchidaceae, Maxillariinae) and a key to the species of Maxillaria sect. Rufescens Christenson from Brazil

“…1). This region is part of the Belem Endemism Center (Amazon Forest), an area with high species richness, but is also a region severely threatened by deforestation (Almeida and Vieira 2010;Martins and Oliveira 2011;Celentano et al 2018).The climate in the area, according to the Köppen classification, is of the type Am (Alvares et al 2013), with average annual temperatures between 26 °C and 27 °C and annual rainfall between 2,300 and 2,500 mm. The rainy season extends from January to June and the less rainy period from July to December (NuGeo 2016).…”

Condições Ambientais E Serviços Ecossistêmicos De Uma Unidade De Conservação De Proteção Integral / Environmental Conditions and Ecosystem Services of an Integral Protection Conservation Unit

“…aos serviços de suporte, uma vez que a ciclagem de nutrientes e a produção primária são dependentes das espécies presentes. Portanto, em pesquisa efetuada no "Mosaico do Gurupi", localizado nos estados do Pará e Maranhão, por Celentano et al (2018), foi indicado que é de fundamental importância o papel de áreas protegidas para a manutenção dos ciclos biogeoquímicos, para a absorção do carbono presente na atmosfera, assim como na regulação do clima regional, e na disponibilidade da água. Dessa forma, de acordo com Favaro e Rossin (2014), a capacidade de resiliência é fundamental para a renovação e reorganização dos ecossistemas, para a capacidade de adaptação e para a saúde ambiental.…”
