    No geral, os textos estrangeiros citados pela geografia física brasileira, tratando da teoria dos geossistemas resumem-se a três artigos de Nikolai Berouchashvili (em francês) e dois de Viktor Sochava (em português). Além destes, destaca-se o texto de Bertrand traduzido para o português em 1972 e o de Maria Bolós (em espanhol). Este trabalho propõe uma atualização conceitual de fundamentos para mapeamento de geossistemas com base em revisão de literatura recente produzida por geógrafos do Leste Europeu (sobretudo da Rússia, Ucrânia, Polônia e Geórgia) e da Oceania (Austrália e Nova Zelândia), áreas onde o conceito de geossistema permanece em voga na ciência geográfica. A maioria das referências tendo sido produzida nos últimos dez anos (a partir de 1999). São apresentadas as unidades da hierarquia dos geossistemas locais (fácies, podurochishches, urochishches, mestnost e landschaft) e seus princípios de classificação (tipológicos, corológicos e dinâmicos). Além disso, são apresentadas técnicas para levantamento em campo expedito e descrição de equipamentos utilizados. Por fim apresenta-se um fragmento de mapa de geossistema para uma área na Mesorregião do Leste Alagoano, juntamente com o mapa é apresentado um perfil descrevendo fácies e subtratos de paisagem (suburochishches). Palavras-chave: Geografia Física Integrada. Mapeamento de geossistemas. Atualização conceitual. Fundamental aspects for geosystems mapping: a conceptual review Generally speaking foreign texts quoted by Brazilian physical geography regarding the geosystems theory are restricted to three articles by Nikolai Berouchashvili (in French), and two by Viktor Sochava (in Portuguese). Beyond those, one must highlight a text by A. Bertrand, translated to Portuguese in 1972, and the original work in Spanish of Maria Bolós. This article proposes a conceptual update of the foundings of geosystems mapping theoretical background, based on a comprehensive literature review of regions where the concept is still in vogue amid the geographical science, such as eastern Europe (mainly, Russia, the Ukrane, Poland and Georgia), and Oceania (Australia and New Zealand). Most of the used references have appeared in literature within the last decade. The hierarchy of local geosystem units is discussed (facies, podurochishches, urochishches, mestnost and landschaft) as well as their classification principles (typological, chorological and dynamics). Further more, field survey techniques and equipments are described. Finally a fragment of a geosystem map for the meso-region of Eastern Alagoas State, in the Northeast of Brazil, is presented along with a transect in which landscape facies and sub-tracts (suburochishches) are described. Key words: Integrated Physical Geography. Geosystems mapping. Conceptual review

    Depósitos Eólicos Inativos do Sub-Médio São Francisco, evidências de atividade eólica durante o Pleistoceno, Pernambuco, Nordeste do Brasil / Eolian Inactive deposits of the Sub-Middle San Francisco, Pernambuco, Northeastern Brazil, eolian activity during the Pleistocene

    This study aimed at understanding the dynamics of the recent geologic evolution in the São Franciscoriver valley, State of Pernambuco. The applied methodology encompasses two types of analysis, a geomorphologicone based on the elaboration of a detailed map, identifying a morphostructural unit andtheir respective morphosculptures. The second analysis was a geochronologic one based on OpticallyStimulated Luminescence. The results pointed to the existence of two sets of eolian morphosculpturesshaped along the late Pleistocene, exhibiting depositional activity until the Holocene transition. Theapplied methodology proved quite satisfactory in this region which is still lacking paleoenvironmentaldata

    AMAZONIA CAMTRAP: a dataset of mammal, bird, and reptile species recorded with camera traps in the Amazon forest

    The Amazon forest has the highest biodiversity on earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed and grey literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazon regions to compile the most extensive dataset of inventories of mammal, bird and reptile species ever assembled for the area. The complete dataset comprises 154,123 records of 317 species (185 birds, 119 mammals and 13 reptiles) gathered from surveys from the Amazonian portion of eight countries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname and Venezuela). The most frequently recorded species per taxa were: mammals - Cuniculus paca (11,907 records); birds - Pauxi tuberosa (3,713 records); and reptiles - Tupinambis teguixin (716 records). The information detailed in this data paper opens-up opportunities for new ecological studies at different spatial and temporal scales, allowing for a more accurate evaluation of the effects of habitat loss, fragmentation, climate change and other human-mediated defaunation processes in one of the most important and threatened tropical environments in the world. The dataset is not copyright restricted; please cite this data-paper when using its data in publications and we also request that researchers and educators inform us of how they are using this data
