“…Maximum temperatures of 30.9 °C were recorded, and the minimum measured was 27.5 °C. observed that M. tuberculatus survives well in temperatures between 18 and 32 °C, and a recent study by Okumura (2006) showed that, in the laboratory, the range of tolerance of this species is between 16 and 37 °C, with an optimum range between 29 and 34 °C. This reinforces the plasticity of this species, which is capable of occupying environments in extreme situations, and is highly competitive.…”

“…M. tuberculatus can reproduce sexually, but reproduces mainly via parthenogenesis, which partly accounts for its success as an invasive organism; it is viviparous. According to Dudgeon (1986), individual snails as small as 0.28 cm can be reproductively mature, although Okumura (2006) observed, in the laboratory, individuals of about 1.0 cm long in their first reproduc- tion. Therefore we assume that most of the individuals found were mature.…”

Records of the gastropod Melanoides tuberculatus (Müller, 1774), family Thiaridae, in the Piranhas-Assu River basin in Rio Grande do Norte reveal the dispersal of this native Southeast Asian and East African species into aquatic environments of the Brazilian semiarid region, including artificial environments (reservoirs) and lotic systems. The eutrophic conditions of the local waterbodies appear to favor the present situation, where this invasive species reaches extremely high densities, sometimes over 10,000 ind.m -2 as in Armando Ribeiro Gonçalves Reservoir. These observations indicate the immediate need for new studies on the spatial distribution of the species and its potential impact on the biodiversity and water quality of the waterbodies of the semiarid region of the state. Implantation of regular and systematic monitoring of the aquatic resources of the region is urgently required. ResumoRegistros da presença do gastrópode Melanoides tuberculatus (Müller, 1774), família Thiaridae, na bacia do Rio Piranhas-Assú no Rio Grande do Norte, revelam a dispersão desta espécie nativa do sudeste asiático e leste africano para ambientes aquáticos do semiárido brasileiro, incluindo ambientes artificiais (reservatórios) e sistemas lóticos. As condições eutróficas dos corpos d'água potiguares parecem favorecer a presente situação, em que a espécie invasora atingiu densidades extremamente elevadas, com valores acima de 10.000 ind.m -2 , como no reservatório Armando Ribeiro Gonçalves. Estas observações indicam a necessidade imediata de novos estudos sobre a distribuição espacial da espécie e seu potencial de impacto sobre a biodiversidade e qualidade da água dos corpos d'água do semiárido potiguar. Neste contexto, torna-se urgente a implantação de um regular e sistemático monitoramento dos recursos hídricos da região.Palavras-chave: Thiaridae, Melanoides tuberculatus, espécie invasora, semiárido brasileiro.

“…Isto porque por ser uma espécie altamente invasiva, uma característica marcante é sua capacidade de colonizar áreas impactadas por atividades antrópicas, principalmente locais de águas rasas, com substrato de granulometria fina e rico em detritos orgânicos (Martins-Silva e Barros, 2001;Okumura, 2006). Estudos realizados por Kock e Wolmarans (2009) também relacionaram a abundância de M. tuberculata em ambientes com substratos lamacentos ou arenosos e em temperaturas de 25°C em média.…”

“…O fluxo natural das águas auxilia na dispersão dos organismos invasores em sistemas aquáticos (Okumura, 2006). Por isso, os ambientes de água doce estão altamente sujeitos às invasões de organismos exóticos já que apresentam grande facilidade para a dispersão pelo próprio fluxo d´água (Welcomme, 1988).…”

Ocorrência de um molusco invasor (Melanoides ceci_mdpa@hotmail.com, adriane_almvaz@hotmail.com, ariane_almvaz@hotmail.com, giselepelzbio@gmail.com, hmsr_@hotmail.com, tata_delunoGarcia@hotmail.com, danielyavelino@uol.com.br, gzacarin@yahoo.com.br RESUMONo Brasil e no estado de São Paulo existem poucos levantamentos sobre a presença do gastrópode Melanoides tuberculata (Müller, 1774). Os moluscos invasores representam uma importante ameaça às espécies nativas, em consequência da sua agressividade na competição pelo uso dos habitats e dos diferentes recursos. Melanoides tuberculata é originário da Ásia e África e a sua introdução no Brasil data da década de 60. Estudos recentes ressaltam a importância de realizar novas pesquisas sobre a distribuição espacial desta espécie e seu possível impacto à biodiversidade. O presente estudo documenta a ocorrência da espécie Melanoides tuberculata na bacia hidrográfica do rio Sorocaba, sua abundância e distribuição espacial em 5 sistemas aquáticos em diferentes estágios de conservação. As amostragens foram realizadas nos meses de junho de 2013 até agosto de 2014, onde foram registrados 522 indivíduos, dos quais 67% foram encontrados no Rio Verde, localizado na zona de amortecimento da Floresta Nacional de Ipanema. Os resultados mostraram que esta espécie pode estar amplamente distribuída na bacia principalmente em locais com substrato arenoso, mata ripária degradada e sujeito a lançamento de esgoto. Deve ser ressaltada ainda a correlação com valores de temperatura da água mais altos, o que pode estar ligado à ausência de sombreamento propiciado pela mata ripária. O controle na proliferação desta espécie, deve ser realizado pela melhoria da qualidade ambiental do ambiente aquáticos uma vez que a erradicação se torna inviável por remoção física. (Müller, 1774). Invasive mollusks pose a major threat to native species as a result of their aggressive competition for habitat use and various resources. Native to Asia and Africa, Melanoides tuberculata was introduced to Brazil in the 1960's. Recent studies have discussed the importance of conducting further research on the spatial distribution of this species and its possible impact on biodiversity. Sampling was conducted from June 2013 to August 2014, and a total of 522 individuals was recorded; 67% of these were found in the Rio Verde River, located in the buffer zone of the Ipanema National Forest. The results showed that this species may be widely distributed in the basin, especially in places with sandy soil, degraded riparian zones, and areas where sewage is discharged. It is important to note the correlation of the distribution with higher water temperatures, which may be related to the absence of shading of riparian forests. Control of the proliferation of this species, which has a high attack potential, must be accomplished by improving quality of the aquatic environment, since eradication by physical removal is unfeasible.

Some communities have moved from the countryside to the city for different reasons, sometimes they have managed to settle in slums and some people go to agricultural production inside the city for their support, by means of a knowledge they bring from the countryside, seeking a place offering them useful resources to produce food, in this sense, urban agriculture as an alternative livelihood and occupation, has a symbolic value, since it is a survival strategy for families [3]. For this reason, this study was carried out within the macro project “Implementación del proyecto educativo comunitario salud alimentaria y productiva en el desarrollo sustentable de la invasión de la carrilera, corregimiento Campoalegre del municipio de Tuluá” (translated: “Implementation of the community educational project, food and productive health in the sustainable development of the invasion community La Carrilera, Campoalegre district of the municipality of Tuluá”), of the Health, Care and Society research groups; GIUR and Agricultural Production, which supported the characterization of the sociodemographic, cultural, environmental and agroecological components in the community of “La Carrilera” that aimed to evaluate and to identify the problems and needs of the study population, through the implementation of surveys, measurement of the biological quality of water based on the methodology used by IDEAM, Roldán and Shannon-Weaver, and the characterization of organic solid waste where the method defined by Marmolejo was implemented, resulting in the identification of the different social groups that make up the community, the occupation of women, the economic income of families, among others. In addition, the high levels of water pollution were manifested with a diversity index of 0.83, indicating the low diversity in the tributary of the community, also the BMWP index presented that the quality of the waters is critical and doubtful, and finally obtained an organic waste production of 60.1% identifying that mainly fruit and vegetable waste is produced. Subsequently, from the diagnosis obtained, some intervention strategies were determined for the conservation of the water resource and sustainable management practices for the use and transformation of organic waste in the study population, which allows adopting urban agriculture and contributing to sustainable development of the sector in the municipality of Tuluá, Valle del Cauca.
