This work analyzed the contribution that the creation of Environmental Protection Areas (EPA) may bring to the conservation of hydrographic basins used as public water sources. The object of study of this work was the hydrographic basin of the Ligeiro River which, by 2022 onwards, will be the new source of public supply in the city of Cianorte-Paraná, replacing the hydrographic basin of the Bolívar stream. The latter has environmental impacts caused mainly by the expansion of urban areas and inadequate practice of land use, occupation, and management, which affects the population’s supply, particularly on days with high levels of rainfall. The study area involved the creation of two municipal EPAs in the hydrographic basin of the Ligeiro River, located in the municipalities of Araruna and Cianorte, with areas of 209.76 km² and 219.82 km², respectively. It is believed that the creation of Environmental Protection Areas in the Ligeiro River hydrographic basin will also present challenges, but it will enable the conservation of natural resources and, especially, of water resources, given the quality of the water. It is expected that these actions will help to minimize or even prevent, in the future, the Ligeiro river hydrographic basin from being as or more impacted as the Bolivar stream basin.

Studies of soils in Environmental Protection Areas (EPAs) are of great importance, because they are an essential component of ecosystems, directly interfering in environmental sustainability. The objective of this study was to evaluate the structural quality of soil cultivated with coffee and used as pasture in the Capituva's River microbasin, which is located in the Environmental Protection Area in Coqueiral, south of the state of Minas Gerais. Uniaxial compression test (preconsolidation test) and soil resistance to penetration were used. Undisturbed samples were taken from the surface layer (0-5 cm) of the soils in the area: a typic dystrophic Red Latosol (LVd - Oxisol), a typic eutrophic Red Argisol (PVe - Ultisol), and a typic dystrophic Haplic Cambisol (CXbd - Inceptisol). A significant linear positive correlation was observed between the results of the preconsolidation test and soil resistance to penetration. Load bearing capacity of soil could be estimated accordingly by means of penetration resistance for LVd, PVe, and CXbd. Cambisol - CXbd showed lower loading support capacity and resistance to penetration than LVd and PVe, due to the better crop management in this soil that resulted in higher physical quality which accounts for higher production and environmental sustainability.

The demand for blackberry has been increasing due to the results of studies on its nutraceutical properties. Moreover, the rusticity of its plants allows its cultivation with reduced use of pesticides, becoming feasible to grow it in areas of environmental protection (APA). As a non-traditional crop in the country and its requirement in specific climatic conditions, there is a lack of studies about management techniques and the adaptability of cultivars in different regions. Thus, it is necessary to study phenological behavior and fruit quality in potential regions. Therefore, this work aimed to verify the adaptability of blackberry cultivars in environmental protection area in Pinhais – PR (Brazil), with no use of pesticides, as well as to evaluate the quality of the fruits produced under this condition, focusing on the recommendation of the cultivars more adapted and the best destination of fruits produced. For this, the phenological and productive performance of seven blackberry cultivars: Tupy, Guarani, Cherokee, Xavante, Brazos, Choctaw, and Arapaho were observed during the cycles of 2017/2018 and 2018/2019. Brazos cultivar had the earliest harvest period, Guarani and Xavante cultivars were intermediate and Tupy and Cherokee cultivars were later in the region. The highest yields were obtained with the cultivars Tupy, Guarani, Xavante, Cherokee, and Brazos. The harvest period extended from November to January. Tupy cultivar produces larger fruits and is the most recommended for marketing as fresh fruit. Other cultivars are recommended for industrialization.

In 2018–2019, we conducted mosquito collections in a municipal vehicle impound yard, which is 10 km from the Serra do Mar Environmental Protection Area in Santo André, SP, Brazil. Our aim is to study arboviruses in the impound yard, to understand the transmission of arboviruses in an urban environment in Brazil. We captured the mosquitoes using human-landing catches and processed them for arbovirus detection by conventional and quantitative RT-PCR assays. We captured two mosquito species, Aedes aegypti (73 total specimens; 18 females and 55 males) and Ae. albopictus (34 specimens; 27 females and 7 males). The minimum infection rate for DENV-2 was 11.5 per 1000 (CI95%: 1–33.9). The detection of DENV-2 RNA in an Ae. albopictus female suggests that this virus might occur in high infection rates in the sampled mosquito population and is endemic in the urban areas of Santo André. In addition, Guadeloupe mosquito virus RNA was detected in an Ae. aegypti female. To our knowledge, this was the first detection of the Guadeloupe mosquito virus in Brazil.

ABSTRACT Dimorphandra mollis is native to the Brazilian Savanna and has social, economic and environmental importance. This study aimed to evaluate the yield and diametric distribution of Dimorphandra mollis Benth. in the Pandeiros River Environmental Protection Area, in Bonito de Minas, Minas Gerais state, Brazil. Five areas were assessed, totaling five hectares (50 plots of 1,000 m2). The total number of plants, yield per plant (2018, 2019 and 2020) and diameter at breast height were recorded, considering all trees from the plots in diametric classes. The average diameter at breast height of all plants was 6.05 ± 3.07 cm, and that of the plants that produced in at least one of the evaluated years was 7.46 ± 3.15 cm. The diametric distribution showed classes with no individuals, indicating imbalance, as well as a trend to inverted “J” shape. The maximum annual yield was 8.08 kg ha-1 of dry fruits (2019), the minimum 0.42 kg ha-1 (2018), and the average 2.74 kg ha-1, with biennial characteristic.

Abstract Amphibian research has grown steadily in recent years in the Amazon region, especially in the Brazilian states of Amazonas, Pará, Rondônia, and Amapá, and neighboring areas of the Guiana Shield. Even so, few data are available for the Amazonian savannas of Brazil. To contribute to the understanding of the diversity of the amphibians of these savannas, we surveyed 15 temporary ponds, six located in open areas, seven on the edge of savanna forest, and two within the forest, in the savanna of the Rio Curiaú Environmental Protection Area (EPA) in Macapá, in the state of Amapá, northern Brazil. Sampling occurred from May 2013 to August 2014 during periods when the ponds contained water. Amphibians were sampled through visual and auditory surveys conducted during both the day- and the nighttime periods on seven days each month over a total of 84 days. A total of 1574 individuals belonging to four families, 12 genera, and 28 species were recorded during the surveys. The cumulative species curve reached the asymptote, indicating that sampling effort was adequate. The number of species was 25% higher than that reported in other studies in Amazonian savannas. Twelve species were recorded for the first time in the savanna of Amapá. Lysapsus boliviana was the most common species (n = 332 of the individuals recorded). The greatest amphibian species richness found in the Rio Curiaú EPA was associated with the savanna mosaic, forest patches, lowland swamp, and temporary ponds. The results of this study contribute to the understanding of the diversity of amphibian species in the Guianan area of endemism in northern Brazil, and also the Amazonian savannas.

AbstractThis review aims to study the main aspects of Maranhense East Mesoregion Biogeography of the state portion has suffered socio-economic and cultural changes, besides environmental conflicts due to the advance of capitalist agriculture as soy and eucalyptus agribusiness. The Maranhense East Mesoregion is formed by the union of 44cities grouped into six microregions: Chapadinha, Coelho Neto, Baixo Parnaíba Maranhense, Chapada do Alto Itapecuru, Codó, and Caxias. Historically, this mesoregion had its occupation linked to peripheral areas to the large cotton plantations of the Itapecuru and cattle creation in Pastos Bons, in the XVII and XVIII century. The economy of this mesoregion is mainly based on Eucalyptus for pulp and paper, soybean, maize, and sugarcane. It must be emphasized that the introduction of the soybean, sugarcane, the expansion of eucalyptus and the charcoal production increased the pollution of the rivers and the destruction of native resources. The lack of inspection as to legal reserve areas in rural properties and the lack of conservation units in this region may be considered as aggravating in relation to the intense expansion of agricultural activities. The vegetation of the Maranhense East Mesoregion encompasses several formations, being basically characterized by the forests of babassu and the areas of cerrado latu senso, besides the small patches of Caatinga near the border with the state of Piaui and transitional formations. The climate is typical of tropical zones, predominantly As in the Parnaíba Delta region and the Aw throughout the rest of the mesoregion, with annual average temperatures between 24°C to 28°C and precipitation index with values between 1800mm to 1000mm. The studied mesoregion has only five Conservation Unit: Mirador State Park, Morros Garapenses State Environmental Protection Area, Parnaíba Delta Environmental Protection Area, Parnaíba Delta Marine Extractive Reserve, Chapada Limpa Extractive Reserve.Keywords: Maranhão geography.

Socioeconomic aspects.CARACTERIZAÇÃO BIOGEOGRÁFICA DA MESORREGIÃO LESTE MARANHENSE (BRASIL)ResumoEsta revisão tem como objetivo estudar os principais aspectos da Biogeografia da Mesorregião Leste Maranhense, porção do estado que tem sofrido mudanças socioeconômicas e culturais, além de conflitos ambientaisdevido ao avanço da agricultura capitalista como o agronegócio da soja e eucalipto. A Mesorregião Leste Maranhense é formada pela união de 44 municípios agrupados em seis microrregiões: Chapadinha, Coelho Neto, Baixo Parnaíba Maranhense, Chapadas do Alto Itapecuru, Codó e Caxias. Historicamente, esta mesorregião teve sua ocupação ligada às áreas periféricas às grandes plantações de algodão do Itapecuru e criação de gados em Pastos Bons, no século XVII e XVIII. A economia desta mesorregião baseia-se principalmente no Eucalipto para a produção de celulose e papel, soja, milho e cana-de-açúcar. Deve-se ressaltar que a introdução da soja, da cana-de-açúcar, a expansão do eucalipto e a produção de carvão vegetal aumentaram a poluição dos rios e a destruição de recursos nativos. A falta de fiscalização quanto às áreas de reserva legal nas propriedades rurais e a falta de unidades de conservação nesta região, podem ser consideradas como agravantes em relação à expansão intensa das atividades agropecuárias. A cobertura vegetal da mesorregião Leste maranhense engloba várias formações, sendo basicamente caracterizada pelas florestas de babaçu e pelas áreas de cerrado lato senso, além das pequenas manchas de caatinga próximas à fronteira com o estado do Piauí e formações transicionais. O clima da região é característico das zonas tropicais, predominantemente As na região doDelta do Parnaíba e o Aw em todo o restante da mesorregião, com temperaturas médias anuais entre 24 °C até 28 °C e índices de precipitação pluviométrica com valores entre 1800 mm a 1000 mm. A mesorregião estudada apresenta apenas cinco Unidades de Conservação: Parque Estadual do Mirador, Área de Proteção Ambiental Estadual dos Morros Garapenses, Área de Proteção Ambiental do Delta do Parnaíba, Reserva Extrativista Marinha do Delta do Parnaíba, Reserva Extrativista de Chapada Limpa.Palavras-chave: Geografia do Maranhão. Conservação ambiental. Aspectos socioeconômicos.

Atualmente a Mata Atlântica é um dos biomas mais fragmentados. O objetivo deste estudo foi diagnosticar a fragilidade ambiental da Área de Proteção Ambiental (APA) Alto Rio Doce em Minas Gerais, por meio da caracterização da distribuição da fragmentação local, bem como da pressão sobre a vegetação. A caracterização da vegetação foi feita por classificação supervisionada, por meio da imagem captada pelo sensor OLI presente no Landsat 8. Apenas 22,3% de toda a extensão da APA, que contém 23.329 hectares, apresenta vegetação, sendo composta por muitos pequenos fragmentos. Além disso, a APA é cortada por estradas, sendo uma delas pavimentada e estadual, o que agrava a situação da fragmentação dos habitats, causando danos tanto a espécies animais quanto vegetais. Concluiu-se que para atingir seus objetivos é preciso a elaboração de um plano de manejo para a área, além de alternativas que permitam a popularização da APA tornando-a mais conhecida pela população local.
