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.

ABSTRACT Charcoal has an economic, social and environmental importance, because in addition to being a source of energy, it generates employment and income in the rural environment. Therefore, knowing your market is fundamental for the decision-making of those segments that depend on this raw material. This work analyzed the regional concentration of charcoal production in the state of Paraíba, Brazil, from 1994 to 2016. The data used to measure the regional production concentration (in tons) of native Paraíba charcoal were obtained from the Brazilian Institute of Geography and Statistics (IBGE) from 1994 to 2016. The indicators used were the Concentration Ratio [CR(k)], the Herfindahl-Hirschman Index (HHI), Theil's entropy index (E) and the Gini Index (G). The main results show that the mesorregions of Borborema and Sertão Paraibano present concentrations in charcoal production from Paraíba. The CR(k) of the municipalities had a low to moderately low concentration and a moderately high to a high concentration for the microregions; the HHI and E showed deconcentration tendencies from competitive markets; the G showed strong to very strong inequality for the municipalities and microregions on average. It is concluded that the concentration of charcoal production at regional levels is not concentrated, even though it presents a moderate concentration in the partial indices [CR(k)] for the Paraíba microregions.

Commercial charcoal production has over time become an indispensable means of livelihood among rural settlers in Nasarawa State. However, charcoal production involves woodland exploitation which contributes to deforestation. Considering the growing significance of charcoal in rural and urban livelihoods in Nasarawa State, this paper analysed the preference of tree species and reasons among commercial charcoal producers in Nasarawa State in view of identifying endangered species and suggesting measures to ensure sustainability of the business. The study employed descriptive survey using both qualitative and quantitative data drawn from primary and secondary sources. Questionnaire was administered to 450 respondents randomly sampled from commercial charcoal producers drawn from 6 communities and 3 LGAs of Nasarawa State. Interviews and Focus Group Discussions were also conducted and the data obtained were analysed using descriptive and inferential statistics in Microsoft Excel and SPSS (version 23). A total of 22 tree species were identified as usable for charcoal production in the study area. Investigation into the producers’ preference of tree species showed that eight (8) were mostly preferred out of which Anogeissus leiocarpus (Marke) (57.3%), Erythrina senegalensis (Madri) (52.2%) and Prosopis Africana (Kirya) (49.1%) were among the top three. Marke, Kirya and Madri were the most preferred species in Akwanga, Doma and Karu production areas respectively. High charcoal yield, good combustion quality, high heat content of resulting charcoal, less ash production were the main reasons for their preferences. Most of the preferred tree species have been depleted to the point that they are no longer commonly found for use among commercial charcoal producers in the state. The most endangered species due to commercial charcoal production were Anogeissus leiocarpus (Marke), Erythrina senegalensis (Madri) and Prosopis Africana (Kirya). However, pressure is currently on Teminalia glocosece (Baushe/Uko), Andira inermis (Gwaska), Ficus Spp (Baure), Vitellaria paradoxa (Kede) and Gardinia aqualla (Gaude) due to the difficulties in finding the endangered ones which constituted the most preferred species among producers in Nasarawa State. It was recommended that state energy policies should incorporate a law recognizing charcoal as a key source of energy in the State, thereby encouraging investments in the activity of commercial charcoal producers. Furthermore, conservation plans and practical measures of replacing the extracted trees from woodlands/forests for commercial charcoal production should form the basis for license issuance for charcoal production.

Radiocarbon Dating of Peat Profile with Metallurgy Industry EvidenceIn this work an age model for a peat core from the site near Żyglin, based on14C is presented. The investigated profile is marked with some possible evidence of early human activity in this region. The earliest metallurgy industry is expected to correspond with charcoal production and the recent increase of metal content in this profile. In this work the Quantulus 1220™ recently purchased was used for14C dating with liquid scintillation counting (LSC) technique. Therefore results of calibration, tests and verification with use of samples from inter-comparison programs (VIRI, FIRI) are also presented.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
