“…The farm occupies approximately 7,000 ha of which about 3,000 ha preserve a fragment of Amazon Forest (Pluvial Forest) traversed by the Macaxeira River and other small stream tributaries of the Maracaçume River. This property supports one of the largest forest fragments with primary Amazonian vegetation in the state (Koch and Araújo-Silva 2014;Celentano et al 2017). The species was photographed with a digital camera, and specimens were collected according to the usual procedures (Fidalgo and Bononi 1989).…”

The distribution of Maxillaria aureoglobula is expanded to northeastern Brazil. This species is probably more geographically widespread than expected, and the new record reported here is a geographical link between the other occurrences of this species in northwestern South America (Colombia and Venezuela) and a recent record from Mato Grosso in the Brazilian Central-West Region. We provide an expanded description of the species, a distribution map, and a key to the Brazilian species of Maxillaria sect. Rufescens.

“…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.…”

“…The Sete Irmãos farm comprises approximately 7,000 ha with circa 3,000 ha of well-preserved Terra Firme and Gallery Forests, which are crossed by the Macaxeira River and other small tributary streams of the Maracaçumé River. This fragment of primary Amazonian vegetation is one on the largest in private areas in Maranhão state (Koch and Araújo-Silva 2014;Celentano et al 2017). 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.…”

“…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.…”

Expansion of the geographic distribution of Rapatea paludosa Aubl. (Rapateaceae) to the state of Maranhão, northeastern Brazil. The occurrence of R. paludosa is reported for the flora of Maranhão from the municipality of Cândido Mendes. This is the second species of the genus found in the state. The collected samples are also the second record of R. paludosa in the Northeastern Region of Brazil, adding information on its geographic distribution. Rapatea paludosa is described, illustrated, and its distribution mapped.

“…No Maranhão, o desmatamento ilegal na área da Amazônia Legal tem como objetivo ceder espaço, principalmente, para atividades como agricultura e pecuária. Os 25% da floresta original mantida neste bioma estão distribuídos na seguinte forma: 70% estão dentro de área protegidas (terras indígenas e Unidades de Conservação), 10% nos assentamentos da reforma agrária e cerca de 20% dispersos nas propriedades rurais (Alencar et al, 2016;Celentano et al, 2017).…”

Este estudo tem como objetivo avaliar o cenário de fragilidade ambiental do baixo Mearim através da caracterização ambiental. Esta região consiste em um ambiente estuarino que abriga uma complexa interface de ecossistemas. O avanço da salinidade proveniente do mar tem alterado drasticamente as paisagens da região. A avaliação desses impactos, passa inicialmente pela compreensão dos ecossistemas de uma forma integrada, contrapondo as abordagens que avaliam isoladamente os atributos ambientais. Para a caracterização ambiental obtiveram-se dados de geologia, geomorfologia, solos, geodiversidade, vegetação, além das séries temporais de desmatamento e queimadas para a avaliação do avanço da antropização. A análise dos resultados indicou sete formações geológicas, cinco unidades geomorfologias, sete tipos de solos, seis classes de vegetação e um relevo que abrange elevações de 0 a 318 metros em relação ao nível do mar. A partir dos resultados do avanço da antropização, o desmatamento mostrou que a série histórica foi proporcional a da área total da bacia hidrográfica; e as queimadas evidenciaram que a média da precipitação anual interfere na quantidade de focos de calor. Desta forma, o ambiente apresenta-se frágil por ser susceptível a inundações devido à suas características topográficas levemente planas e às intervenções antrópicas, como o desmatamento e as queimadas, que facilitam a baixa proteção dos solos, sendo vulneráveis à erosão pluvial e ao escoamento. The scenario of environmental fragility from the low course of the Mearim River A B S T R A C TThis study aims to evaluate the environmental fragility scenario of the low Mearim through the environmental characterization. This region consists of an estuarine environment that houses a complex interface of ecosystems. The advancement of salinity from the sea has drastically changed the landscape of the region. The evaluation of these impacts initially involves the understanding of the ecosystems in an integrated way, opposing the approaches that evaluate the environmental attributes alone. For the environmental characterization, geology, geomorphology, soils, geodiversity, vegetation, besides the time series of deforestation and fires were obtained for the evaluation of the advance of the anthropization. The analysis of the results indicated seven geological formations, five geomorphological units, seven types of soils, six vegetation classes and a relief that covers elevations from 0 to 318 meters in relation to sea level. The results of the advancement of anthropization, deforestation showed that the historical series was proportional to that of the total area of the river basin; and fires have shown that the average annual precipitation interferes with the amount of heat sources. As a result, the environment is fragile because it is susceptible to flooding due to its slightly flat topographic features and anthropogenic interventions, such as deforestation and fires, which facilitate low soil protection and are vulnerable to rainfall erosion and runoff.Keywords: Hydrogeology, Geotechnology, Geoprocessing.
