A Mata Atlântica é reconhecida internacionalmente como uma das maiores e mais importantes florestas tropicais do continente sul-americano e além de sua importância para a biodiversidade, esse Bioma exerce importante função no ciclo de carbono. O objetivo deste trabalho foi desenvolver e aplicar uma rotina de detecção de mudanças dos estoques de volume, biomassa e carbono de 2000 a 2015 na Bacia do Rio Iguaçu, Estado do Paraná. Foram utilizadas imagens Landsat-7 ETM+ para o ano 2000 e Landsat-8 OLI para o ano de 2015 totalizando dez cenas para cada período. Foi desenvolvido uma rotina em Python e implementado no Software ArcGIS 10.4 para realizar a automatização de um processo de cálculo de estimativa de volume, biomassa e carbono para os remanescentes de vegetação natural. Houve acréscimo de 15,21% em volume, 14,95% em biomassa, 14,96% em carbono não considerando os estágios sucessionais nem subdivisão por fitofisionomia na bacia do Rio Iguaçu.  Desta forma, concluiu-se que a região de estudo está colaborando de forma positiva para a remoção de dióxido de carbono da atmosfera.Palavras-chave: bacia do rio Iguaçu; mudanças climáticas; sequestro de carbono. DYNAMICS OF VOLUME, BIOMASS AND CARBON IN THE ATLANTIC FOREST BY A CHANGE DETECTION TOOL ABSTRACT: The Atlantic Forest is recognized internationally as one of the largest and most important tropical forests in the South American continent and besides its importance for biodiversity, this biome plays important role in the carbon cycle. The objective of this work was to develop and apply a routine of detection of changes in volume, biomass and carbon stocks from 2000 to 2015 in the Iguaçu River Basin, State of Paraná. They were used Landsat-7 ETM+ images for the year 2000 and Landsat-8 OLI images for the year 2015 totaling ten images for each period. A routine was developed in Python and implemented in ArcGIS 10.4 Software to perform the automation of a calculation process of volume, biomass and carbon estimation for the remnants of natural vegetation. There was an increase of 15.21% in volume, 14.95% in biomass, 14.96% in carbon, not considering successional stages nor subdivision by phytophysiognomy in the Iguaçu River basin. Thus concludes that the region of study is collaborating in a positive way for the removal of carbon dioxide from the atmosphere.Keywords: Iguaçu river basin; climate changes; carbon sequestration.

Controlling the invasion of non-native fish species necessitates a complete understanding of the distribution of these species and the key factors that influence such distribution. In order to research the situation of non-native fish and the relevant influencing factors in the Liao River Basin, we investigated and analyzed the characteristics of the distribution and the trophic levels of non-native fish species, as well their response to different types of factors in the basin. Nine non-native fish species were found during the investigation, and the trophic levels of these species ranged between 2.00 and 3.84. The results of generalized linear models indicate that the distribution of non-native fish species in the basin is mainly related to anthropogenic activities, socioeconomic development, and climate. The southeastern part of the Liao River Basin is conducive to the distribution of non-native fish species. Furthermore, on a spatial scale, we also found that the mean trophic level of non-native fish species was not correlated with anthropogenic activities and socioeconomic development in the Liao River Basin. By providing evidence for the links between non-native fishes and different types of factors, our study contributes to increasing the relevant references for and experiences in the early detection and management of non-native fishes on a basin scale.

The present study aimed to create an inventory of non-native fish species in the basin of the Sorocaba river, located at Upper Rio Paraná. Fish were collected between August 2010 and January 2012 using nets with meshes, round shaped fishing nets, hand net and electric fishing equipment, as well as contacts with fishermen to seek information on species captured in the basin. Besides, we used published data and information contained in reports, monographs and thesis. Five non-native fish species were collected: Tilapia rendalli, Oreochromis niloticus, Pterygoplichthys anisitsi, Poecilia vivipara and Triportheus nematurus that represented 10.63% of all fish species captured in the basin of the Sorocaba river. The occurrence of eight other species, although they were not collected by the sampling program of this study, had already been reported in previous studies, and had already been captured by amateur and professional fishermen, particularly in the reservoir of Itupararanga and in the urban stretch of the Sorocaba river.

Long Term Study

In reservoir cascades, effects on fish assemblages are expected to strengthen over time and transfer from one reservoir to an adjacent one. To test this, fish-assemblage data from 23 years of monitoring in the Araguari reservoir cascade system, upper Paraná River basin, were analysed. The results showed a clear reduction in richness of native and migratory fish species and an increase of non-native species, following reservoir formation. Migratory species richness was higher in reservoirs that presented habitats similar to lotic stretches or tributaries upstream of the impounded area. There was a clear tendency for native species to decline and non-native fish species to increase, in a downstream direction. Fish assemblages became increasingly dissimilar as reservoirs became more distant from each other (longitudinal gradient) and were dominated by small and medium-sized species. Alongside longitudinal position, reservoir area, age and the presence of herbivorous non-native fish were found to be important predictors of variation in fish-assemblage structure. Results from the present study help clarify the potential accumulated impacts of reservoir cascades on fish diversity, which must be carefully considered in river-basin inventories for hydropower plants, and reinforce the importance of long-term monitoring, considering longitudinal and lateral dimensions of the basin.

Diante desse problema, uma possibilidade de melhorar a compreensão do comportamento hidrológico, é a utilização de tecnologias, em especial a integração do SIG com a modelagem hidrológica. O presente estudo teve como objetivo testar a aplicabilidade do modelo hidrológico SWAT para estimação de vazões em um trecho da bacia hidrográfica do rio Paraibuna - Vale do Paraíba, região da Mata Atlântica, um dos formadores do rio Paraíba do Sul. Os dados climáticos e fluviométricos foram coletados com uma série histórica de 22 anos. Na calibração e validação verificou-se boa aderência entre os dados simulados e observados, ou seja, os valores simulados reconheceram os picos e recessões dos valores observados. Os índices estatísticos (NS, PBIAS, RSR e R²) calculados foram qualificados como “muito bom” para a estimação das vazões. Os resultados confirmaram a aplicabilidade do modelo, dessa forma, pode servir como ferramenta para planejamento e gestão de políticas públicas dos recursos hídricos em bacias hidrográficas, na região da Mata Atlântica. O modelo hidrológico SWAT mostrou-se muito bom e apto para estimação de vazões e do balanço hídrico na área de estudo.   Palavras-chave: água, calibração, mata atlântica, validação, vazão     MARMONTEL, C.

APPLICABILITY OF THE SWAT HYDROLOGICAL MODEL IN PARAIBUNA RIVER BASIN, SP – BRAZIL     2 ABSTRACT   The water available for human consumption is becoming increasingly scarce. Faced with this problem, one possibility to improve the understanding of water behavior, is the use of technologies, particularly the integration of GIS with hydrological modeling. The present study is intended to test the applicability of SWAT hydrological model for flow estimation in the stretch of Paraibuna river basin - Paraiba Valley, in the Atlantic Forest region, in the state of São Paulo, one of the tributaries of Paraíba do Sul river.  Climatic and fluviometric data were collected with a historical series of 22 years. In the calibration and validation, good adherence was observed across simulated and observed data, that is, the simulated values recognized the peaks and recessions of the observed values. The statistical indices (NS, PBIAS, RSR and R²) calculated were qualified as "very good" for the estimation of flows. The results confirmed the applicability of the model, so it can serve as a tool for planning and management of water resources public policies in watersheds, in the Atlantic Forest region. The SWAT hydrological model was very good and suitable for estimation of flow and water balance in the stretch of the Paraibuna river basin.   Keywords: water, calibration, forest hydrology, atlantic forest, validation, discharge
