    Castor bean (Ricinus communis L.) is a crop of great potential for the region of Irecê - Bahia, which has favorable soil and climate conditions for its planting and has been standing out as an important alternative for the development of family agriculture in the region. However, the quality of castor bean seeds can be affected by several factors during the production process. In this context, the objective of this study was to analyze the main techniques for planting and storing castor oil seeds used by family farmers in the region of Irecê - Bahia, and to identify possible obstacles in production, relating them to the existing technical knowledge. For data collection, 10 farmers were interviewed between October and November 2019 through a semistructured questionnaire on castor bean cultivation techniques. It was noted that farmers commonly face difficulties in producing and draining production. Irregular and scarce rainfall, the use of low quality seeds, insufficient labor, compacted soil, pests, and lack of support and financing have been the main obstacles to production. That said, it is necessary to seek measures to eliminate or mitigate these failures, such as new projects for the construction of UTD, distribution of certified seeds, intensification of technology, adding producers to cooperatives, support from managers and incentives to producers; so that the social objectives of increasing castor bean production in the best quality standard and consequently, income generation in the region are achieved.

    Diversidade de morcegos em floresta de restinga no município de Camaçari-Ba
    (Universidade Católica do Salvador, 2020-12-19) França, Roger Cardoso e Silva; Tinôco, Moacir Santos; http://lattes.cnpq.br/; Alencar, Débora Magnavita de; http://lattes.cnpq.br/; Dias, Marcelo Alves; http://lattes.cnpq.br/; Leite, André Kaufer; http://lattes.cnpq.br/
    One of the biggest problems faced by the original natural areas is the disordered population growth, which advances on the native vegetation, increasingly surrounding and making cuts in its interior, leading to the loss of its biodiversity. These areas, even separated from their original matrix, continue to provide diverse ecosystem services to humans and provide shelter for wildlife. Bats, although little studied in urban environments, have the facility to adapt to modified environments end up using these cutouts and sharing space with man. Among the various environmental services, chiropractors act as pollinators, agricultural pest controllers, dispersal of pioneer seeds essential for the regeneration of degraded areas, transmission of zoonoses and excellent indicators of environmental quality. This study aimed to investigate the richness of bat species that live in Busca Vida, a remnant of restinga forest in Camaçari - BA. The survey was conducted during the months of (March to September) through the use of fog nets at different points during three nights. Five species and 43 specimens belonging to the family Phyllostomidae were found. The predominant species in all points was Artibeus planirostris with 28 individuals, and Carollia perspicillata with 9 individuals showing the importance of this area for maintenance and conservation. The low number of species found in the study area may be related to effort in only one season, suggesting the use of other sampling methods, increased sampling effort and exploitation of other seasons.

    As serpentes na percepção dos moradores da comunidade de Massarandupió, Entre Rios-Ba
    (Universidade Católica do Salvador, 2020-12-10) Lima, Liny de Jesus; Marques, Jamille Ferreira; http://lattes.cnpq.br/; Tinôco, Moacir Santos; http://lattes.cnpq.br/; Rossi, Juan Carlos; http://lattes.cnpq.br/; Dias, Marcelo Alves; http://lattes.cnpq.br/; Argôlo, Antônio Jorge Suzart; http://lattes.cnpq.br/
    Among popular understanding, snakes are mystical beings, surrounded by distorted beliefs and views about their ecological relevance. Despite its importance, the common perception most of the times is that snakes always represent a threat. In this context, the present study aimed to investigate the perception of the inhabitants of the Massarandupió-BA Community, about snakes, seeking to understand the relationship that these people have with these animals. Data were collected from September to November 2020, through semi-structured interviews, conducted with 20 residents, 15 women and 5 men. It was found that these animals are still negatively present in the minds of most respondentes. However, the relationship between them was not so conflicted, given the fact that snakes are not killed by the majority. However, the infinity of myths and legends that are built around snakes, can contribute to a rooted culture that these animals always represent a threat to humans, which can lead to indiscriminate attack on species. And although most respondents are aware that the preservation of snakes is important, many are still unaware of the ecological role they play in nature. Thus, works that focus on environmental education regarding the biology and importance of snakes become essential, which can be an important tool to disseminate correct information about this group. Therefore, it is hoped that the information obtained will serve as indicators to create awareness and conservation strategies with communities.

    Utilização de espécies de cladóceros (Crustacea: Brachiopoda) em ensaios ecotoxicológicos
    (Universidade Catolica de Salvador, 2019-06-10) Oliveira, Philipe Costa de; Silva, Eder Carvalho da; http://lattes.cnpq.br; Silva, Daniel de Abreu Seixas; http://lattes.cnpq.br; Dias, Marcelo Alves; http://lattes.cnpq.br
    The intense human activity on nature contributes to its degradation, being the aquatic environment, among the natural resources, the most susceptible to impacts of human activity, since they are used as a place of disposal of domestic and industrial effluents. Ecotoxicology has emerged as a science that studies and evaluates the effects of physical and chemical agents on living organisms and their natural organizations (populations, communities and ecosystems). Through biomonitoring and toxicity tests, organisms are used as tools for a response (acute or chronic toxicity), given that only physical-chemical analyzes are not sufficient to determine potential effects on biota. The cladocerans, known as "water fleas" (Crustacea: Brachiopoda) are planktonic and filtering organisms that feed on particles, algae and other organic debris in aquatic environments in which they are inserted, very sensitive to environmental changes and, given to this characteristic, they are submitted to the most diverse types of pollutants in ecotoxicological tests, since they are in initial levels of the food chain, serving as food preferentially for fishes, being able to affect other instances of the food chain. In a literature review of the last 10 years (2009-2018), the exotic species Daphnia similis and Ceriodaphnia dubia were the most used species for acute and chronic toxicity studies, respectively, considering tests that include environments contaminated with heavy metals (As, Cd, Cr, Cu, Zn), chemical and nanoparticulate (Ag, Ti), besides its use for the measurement of river and basin quality. The species Ceriodaphnia silvestrii and Daphnia magna were used to compose analyzes of water bodies under the influence of agrochemicals and xenobiotics, also serving as a tool to trace sources of pollution. The native species Daphnia laevis and Macrothrix flabelligera were the least selected to compose studies. The criteria used to select the most used species were: wide distribution of organisms, short life cycle, rapid reproduction and, associated with these characteristics, establishment of protocols by the Brazilian Association of Technical Standards (ABNT) and CETESB, regarding the preparation, management and use of these species. It was concluded that the versatility and differences in the sensitivity of the organisms to the tests that were submitted contribute to the selection of these, including the technical and legal support of the existing protocols, however, it is important to continue research that has the purpose of inserting other species native to the legal regulations, for greater reliability in the results, besides works that increasingly aim at the maintenance, control and conservation of water bodies, consolidating cladocerans as important tools of ecotoxicology and biomonitoring
