ABSTRACT
RESUMO A eco-hidrologia busca integrar os conhecimentos da hidrologia aos da ecologia, criando uma abordagem mais ampla para a compreensão da dinâmica dos recursos hídricos, facilitando o planejamento e as ações de programas de gestão. Uma das formas de integrar hidrologia à ecologia é por meio da elaboração de índices de adequabilidade de hábitat (IAHs), processo que tem se destacado por fornecer informações relevantes sobre áreas úmidas. O IAH é obtido pela relação entre as informações sobre espécies bioindicadoras e as condições eco-hidrológicas necessárias à sua sobrevivência, permitindo a avaliação de impactos sobre as espécies. O desenvolvimento de IAHs, integrados a processos de modelagem hidrodinâmica e sistemas de informação geográfica (SIGs), proporciona a obtenção de imagens de adequabilidade de hábitat, que permitem obter informações espacializadas sobre a qualidade do hábitat de determinada espécie, ou grupo de espécies, colaborando para o aperfeiçoamento das estratégias de gerenciamento dos recursos hídricos e a conservação da biodiversidade de áreas úmidas. A fim de melhor elucidar o processo de desenvolvimento de IAHs e sua aplicação, é apresentada a metodologia utilizada para avaliar a adequabilidade do Banhado do Taim, inserido na Estação Ecológica do Taim, importante área úmida localizada no sul da planície costeira do Rio Grande do Sul.
ABSTRACT The ecohydrology aims at integrating the concepts of hydrology and ecology, creating a broader approach to understand the water resources' dynamics, facilitating the plan and management of resources. One way to integrate hydrology with ecology is by developing Habitat Suitability Index (HSI), a process that stands out by providing relevant information on wetlands. HSI is obtained by relating the information about the bioindicators and ecohydrological conditions necessary to ensure these species' survival, enabling to evaluate the impacts on them. The development of HSIs integrated with hydrodynamic modeling and Geographic Information Systems (GIS) allows us to obtain spatialized habitat suitability information, that provide information about the quality of a species' (or group of species') habitat, contributing to the improvement of water resources management strategies combined with the biodiversity conservation in wetlands. Regarding this, the present article presents the HSI's development process and its application to evaluate the suitability of the Taim Basin, inserted in Taim Ecological Station, an important Southern Coastal wetland located in the State of Rio Grande do Sul.
ABSTRACT
Arab countries have long tradition of using traditional medicine which enjoys mass foundation among local people. Recently, China's import and export trade of traditional medicine products with Arab countries showed an increasing trend year by year. With the implementation of the Belt and Road Strategy, Arab countries played a more important role in China's foreign trade. With the aim of promoting the spread of traditional Chinese medicine (TCM) in Arab countries, cooperation with relevant countries shall be differentiated. The Gulf region is economically advanced with its people enjoying prosperity, where is suitable for developing TCM product and service trade. The Levant has strong advantages in traditional medicine research, where academic communication shall be frequented. Countries in north Africa enjoy profound traditional friendship with China, where are suitable for dispatching Chinese foreign aid medical team to promote TCM. Meanwhile, we are supposed to take advantage of Confucius Institute and Chinese culture centers as platforms to spread TCM culture, to strengthen cooperation with medical universities and research institutions in the target countries, to enroll more Arab students to study TCM, to develop international standard Chinese-Arabic basic nomenclature of Chinese Medicine, and to carry out Traditional Arabic & Islamic Medicine researches.
ABSTRACT
In the present study, we examined the role of different habitat components and their relationship with microhabitat use by three species of egret: Cocoi heron (Ardea cocoi), Great egret (Ardea alba), and Cattle egret (Bubulcus ibis), in wetlands of southern Brazil. Ardea alba and A. cocoi were not habitat-specific (e.g. vegetation cover and flooding level). Conversely, B. ibis was associated with drier microhabitats. Relative air humidity and air temperature were the main variables which correlated with the occurrence of these species and supported the plasticity of B. ibis and its predominance in drier habitats.
No presente estudo foi avaliado o papel de diferentes componentes do habitat e sua relação quanto ao uso do microambiente por três espécies de Ardeidae: garça-moura (Ardea cocoi), garça-branca-grande (Ardea alba) e garça-vaqueira (Bubulcus ibis), em banhados do extremo sul brasileiro. Aparentemente, A. alba e A. cocoi não apresentaram especificidade a algum tipo de habitat (e.g. cobertura vegetal e nível de alagamento). Por outro lado B. ibis revelou associações a microambientes mais secos. A temperatura do ar e umidade relativa do ar foram as principais variáveis correlacionadas com a ocorrência dessas espécies, além disso, reforçou-se a plasticidade de B. ibis e sua predominância em ambientes secos.

Feeding strategy and mouth morphology of jundiá in costal lagoons of south of Rio Grande do Sul were studied. Gut contend of 189 individuals were collected from 2002 to 2004 and analysed according Amundsen. Fishes and crustaceans were the feeding items more frequent in the diet. Mollusk, insects and plants had low FO%. Season variation in diet showed lower variety of feeding items during summer and higher in winter. The diet vary according to site were irrigation channels showed low FO% for all items. The jundiá showed generalist feeding strategy, generally preying on fish and crustaceous. On the description of its feeding apparatus the importance on the capture prey was observed.
