Abstract Cooking encompasses cultural, environmental, social, economic, and political dimensions, as well as composes the activities contained in a food system and promoting dialogues and transformations. This study aims to describe and to analyze everyday elements related to cooking and its relationship with the food system based on the experience of a group of female urban farmers in the east side of the city of São Paulo. Body-map storytelling was used, a creative visual research method, in which, by drawing the participant’s body contours, visual and oral data were produced on the meanings of cooking. Seven women participated in this study, who develop actions related to agriculture and cooking. The generated data were analyzed using thematic analysis. Cooking proved to be a connector from the field to the table, strengthening and being strengthened by the practices of urban and peri-urban farming, and is an interesting tool to promote health, contemplating biopsychosocial well-being in line with issues of social, economic, and environmental sustainability. Understanding this connection enables to support public policies to promote sustainable food systems and facing the challenges of the Anthropocene.

Abstract We propose a new species of the troglobitic genus Spelaeogammarus da Silva Brum, 1975, with data on its distribution, ecology, aspects of behavior, and conservation status. Spelaeogammarus ginae sp. nov. occurs in a single cave in the Serra do Ramalho karst area, of the northeastern Brazilian semi-arid region. We also provide new data on the distribution and conservation status of its congener, Spelaeogammarus spinilacertus Koenemann and Holsinger, 2000 that occurs in the upper phreatic aquifer inside caves from Chapada Diamantina domain. Both species occur in caves in the state of Bahia, northeastern Brazil.

RESUMO O conhecimento acerca da dieta de uma determinada espécie é essencial para fornecer informações sobre o crescimento e manutenção das populações em ambiente natural. Macrobrachium brasiliense (Heller, 1862) é uma espécie de camarão de água doce com ampla distribuição no Brasil, ocorrendo frequentemente em ambientes aquáticos inseridos no bioma Cerrado. O objetivo deste estudo foi avaliar a dieta natural de uma população de M. brasiliense, comparando os itens alimentares consumidos em função do sexo, sazonalidade e tamanho corporal dos indivíduos. Foram realizadas coletas mensais entre setembro de 2018 a agosto de 2019. Os indivíduos coletados tiveram seu sexo identificado e o comprimento do cefalotórax mensurado. O conteúdo estomacal foi avaliado a partir do grau de repleção, método de pontos e de frequência de ocorrência. Verificou-se elevada frequência de detrito vegetal no conteúdo estomacal e uma frequência menor de insetos aquáticos, porém significativa. Não houve diferenças significativas quanto à dieta de machos e fêmeas e entre as estações seca e chuvosa. Foi observado um aumento do consumo total de insetos com aumento de tamanho de machos e fêmeas de M. brasiliense. Uma preferência de dieta por Trichoptera foi registrada em ambos os períodos de amostragem para machos e fêmeas.Os resultados obtidos confirmam uma dieta onívora para a espécie e sugerem que a composição e a proporção de itens podem variar em função do tamanho dos indivíduos e da disponibilidade dos itens no ambiente.

ABSTRACT Knowledge about the diet of a given species is essential to provide information on the growth and maintenance of populations in a natural environment. Macrobrachium brasiliense (Heller, 1862) is a species of freshwater prawn widely distributed in Brazil, being frequent in aquatic environments inserted in the Cerrado biome. The aim of this study was to evaluate the natural diet of a population of M. brasiliense, comparing the consumed food items according to sex, seasonality and body size of individuals. Monthly collections were carried out between September 2018 and August 2019. The individuals collected had their sex identified and the length of the cephalothorax measured. Stomach content was assessed based on the degree of repletion, the method of points and the frequency of occurrence. There was a high frequency of plant material in the stomach contents and a smaller but significant frequency of aquatic insects. There were no significant differences regarding the diet of males and females and between the dry and rainy seasons. It was observed an increase in total insect consumption with the increase in size of males and females of M. brasiliense. A diet preference for Trichoptera was recorded in both sampling periods for males and females. The results obtained confirm an omnivorous diet for the species and suggest that the composition and proportion of items may vary depending on the size of the individuals and the availability of the items in the environment.

RESUMO O objetivo do presente estudo foi avaliar a influência de fatores abióticos (condutividade, oxigênio dissolvido, pH, precipitação e temperatura da água) na abundância de Macrobrachium amazonicum (Heller, 1862), bem como comparar o crescimento relativo entre as categorias demográficas ao longo das estações do ano, em uma lagoa marginal localizada no município de Perdões, em Minas Gerais. Os camarões foram coletados mensalmente, de agosto de 2013 a julho de 2014, em macrófitas do gênero Eichhornia com o uso de uma peneira semicircular. No laboratório, os espécimes foram categorizados em juvenis, machos, fêmeas e fêmeas ovígeras, e medidos quanto ao comprimento total (CT), comprimento da carapaça (CC) e comprimento do abdome (CA). O predomínio de juvenis foi evidente, representando 74,4%, seguido por 16,7% machos, 6,1% fêmeas e 2,8% fêmeas ovígeras. A abundância total e a abundância de juvenis, machos e fêmeas foram correlacionadas negativamente com a condutividade. O crescimento relativo do CT e CA, em relação ao CC, foi diferente para juvenis, machos e fêmeas ao longo de todo ano, exceto durante o verão (para CT e CA) e o outono (para CA), quando o mesmo padrão foi observado para as três categorias demográficas (p>0,05), possivelmente devido à maior abundância de indivíduos jovens obtida durante estas estações. Esta maior abundância de juvenis pode estar relacionada à sua ocorrência em microhabitats que forneçam refúgio como Eichhornia. Apesar de algumas características semelhantes aqui observadas em relação às demais populações ao longo de sua distribuição geográfica, como o elevado número de juvenis e o menor tamanho dos machos em comparação às fêmeas, o presente estudo fornece informações que ampliam o conhecimento sobre a plasticidade de M. amazonicum, principalmente com relação ao local de amostragem - uma lagoa marginal. Desta forma, os resultados obtidos ampliam a compreensão sobre a vasta ocorrência da espécie e suas respectivas adaptações nos mais variados habitats, contribuindo para a elaboração de diretrizes de conservação e manejo para M. amazonicum e para o meio que habita.

ABSTRACT The aim of the present study was to evaluate the influence of abiotic factors (conductivity, dissolved oxygen, pH, precipitation, and water temperature) on the abundance of Macrobrachium amazonicum (Heller, 1862), as well as to compare the relative growth among demographic groups throughout the seasons in a lagoon system located in the municipality of Perdões, Minas Gerais. Monthly, from August/2013 to July/2014, the prawns were collected on macrophytes of the genus Eichhornia using a semi-circular sieve. In the laboratory, the specimens were categorized into juveniles, males, ovigerous females and non-ovigerous females, and measured as total length (TL), carapace length (CL), and abdomen length (AL). The predominance of juveniles was evident, representing 74.4%, followed by 16.7% males, 2.8% ovigerous females and 6.1% non-ovigerous females. The total abundance and the abundance of juveniles, males, and females were negatively correlated with conductivity. The relative growth of TL and AL, in relation to CL, was different for juveniles, males and females thought the year, except during summer (for TL and AL) and autumn (for AL), when the same pattern was observed for the three demographic categories (p>0.05), possibly due to the highest abundance of juvenile individuals obtained in these seasons. The highest abundance of juveniles can be related to its occurrence in microhabitats that provide refuge, as Eichhornia. Despite some similar characteristics here observed in relation to the other populations throughout its distribution, as the high number of juveniles and the smaller size of males compared to females, the present study provides information that expands the knowledge on the plasticity of M. amazonicum, considering the sampled local - a lateral lagoon system. The obtained results promote the comprehension of the vast occurrence of the species and its adaptations to each specific environment, contributing to the elaboration of conservation and management guidelines for M. amazonicum and for the environment where it inhabits.

RESUMO Compreender a relação entre corpo, saúde e movimento além do determinismo biológico e do paradigma biomédico vigente consistiria em considerar outras interpretações emergentes e que consideram a multiplicidade das inúmeras dimensões das quais a tríade pode ser composta, além das diferentes relações que poderiam existir entre si. O paradigma da complexidade é apresentado neste ensaio com o propósito de amparar outras interpretações da atividade física que sejam menos simplificadoras, lineares e causais e que possam incorporar a abertura, a incompletude, a incerteza e a transdiscipliniridade. A teoria da complexidade representa uma estimulante e potente contribuição para o estudo dinâmico do processo saúde-doença e a questão da atividade física nesse panorama.

ABSTRACT Understanding the relationship between body, health, and movement beyond biological determinism and the current biomedical paradigm should consider other emerging interpretations that consider the multiplicity of the innumerable dimensions of which the triad can be composed as well as the different relationships that could exist between them. The paradigm of complexity is presented in this essay with the purpose of supporting other interpretations of physical activity that are less simplifying, linear and causal and that can incorporate openness, incompleteness, uncertainty and transdisciplinarity. The theory of complexity represents a stimulating and potent contribution to the dynamic study of the health-disease process and the physical activity in this panorama.

Resumo: Este trabalho teve por objetivo caracterizar as estratégias reprodutivas de uma população de Hyalella bonariensis no sul do Brasil, avaliando o sucesso de pareamento, o período reprodutivo de machos e fêmeas, a fecundidade e o tamanho corporal dos indivíduos durante a reprodução. Para isso foram realizadas quatro amostragens (Agosto/2012, Outubro/2012, Janeiro/2013 e Abril/2013) utilizando-se uma rede de mão, com malha de 250 µm, durante 20 minutos por um coletor. Em campo, os casais e as fêmeas ovígeras foram individualizados e em laboratório os mesmos foram mensurados quanto ao comprimento do cefalotórax (CC) (mm) e os ovos ou juvenis encontrados dentro do marsúpio foram contados. O CC médio dos machos e fêmeas pareados foi significativamente superior ao dos machos e fêmeas não pareados. Um dimorfismo sexual no tamanho corpóreo foi observado na população - ambos machos pareados e não pareados foram maiores do que as fêmeas. Aparentemente os machos maiores têm uma maior probabilidade de perder fêmeas durante o comportamento precopulatório. Foi observada correlação positiva entre o tamanho dos machos e fêmeas que foram encontrados formando casais - machos maiores geralmente pareiam com fêmeas maiores e machos menores com fêmeas menores (r=0,81). O sucesso de pareamento dos machos aumentou com o tamanho corpóreo e podemos assumir que os machos de todas as classes de tamanho são capazes de encontrar parceiras sexuais; entretanto, o sucesso de pareamento das fêmeas não depende do tamanho das mesmas, sendo que as fêmeas pareadas e não pareadas apresentaram CC médio semelhante. O sucesso reprodutivo da espécie aumentou com o tamanho corpóreo em machos e fêmeas, sendo mais pronunciado nos machos. As fêmeas pertencentes às maiores classes de tamanho apresentaram sucesso reprodutivo nulo. Os resultados suportam a ideia que as fêmeas grandes poderiam ter uma baixa probabilidade de encontrar parceiro para formar par pré-copulatório, quando comparada às fêmeas de tamanhos inferiores, apesar das fêmeas maiores serem mais fecundas. Neste sentido, as menores fêmeas possuem um sucesso de pareamento maior, pois elas são capazes de copular com uma elevada proporção de machos. A fecundidade média da espécie foi estimada em 17,4 (± 3,89) ovos/juvenis. Os resultados observados no presente trabalho assemelham-se aos encontrados para outras espécies do gênero já analisadas no sul do Brasil.

Abstract: The aim of this study was to characterize the reproductive strategies of a population of Hyalella bonariensis from southern Brazil. Pairing success, reproductive period of males and females, fecundity, and body size at the onset of reproduction were evaluated. Animals were sampled four times (August 2012, October 2012, January 2013, and April 2013) with the 250 µm-mesh dip net during 20 minutes by only one person. In the field, precopulatory pairs and ovigerous females were individualized. In the laboratory, cephalothorax length (CL) were measured and eggs and juveniles were removed from the females' marsupium and counted. The mean CL of paired males and females was significantly higher than that of non-paired males and females. A sexual dimorphism in body size was observed in the population - both paired and non-paired males were larger than females. Probably larger males have a higher probability of losing females during precopulatory behavior. A significant correlation was observed between the size of paired males and females - larger males often paired with larger females and smaller males paired with smaller females (r = 0.81). The pairing success of males increased with body size and we can assume that males from all size classes are able to find mates. The pairing success of females was independent of body size - paired and non-paired females had similar mean CL. The reproductive success increased with body size in males and females, and was more evident in males. Females from the largest size classes had null reproductive success. The idea that larger females can produce more eggs but might have a lower probability of finding a mate than smaller females was corroborated by our results. Therefore, smaller females have higher pairing success because they are capable of mating with a higher percentage of males. The estimated mean fecundity of H. bonariensis was 17.4 (± 3.89) eggs/juveniles. Our results are similar to those of other species of Hyalella from Brazil.

Abstract The goal of this study was to evaluate the reproductive investment (RI) and the fecundity of the shrimp Nematopalaemon schmitti (Holthuis, 1950), caught by trawling in the southeastern Brazilian coast in 2008, 2009 and 2011. The carapace length (CL) of ovigerous females was measured and the development stage of their ovaries and embryos were analyzed. A significant relationship was observed between the female body and embryo weights (Linear regression: r² = 0.26, F = 20.77, P < 0.0001, Ln BDW = 0.92. Ln FBDW - 2.24) and between number of embryos and CL (Linear regression; stage I: r² = 0.38, F = 36.15, P < 0.0001; stage II: r² = 0.34, F = 14.10, P < 0.001), but not between the RI and CL (ANOVA: F = 0.47, df = 7, P = 0.85). Association of the changes in embryo development and ovarian maturation of ovigerous females was tested. Females with rudimentary ovaries predominantly showed embryos in stage I (early development) and females with developed ovaries only showed embryos in stage II (final development), showing synchrony between the development of both, thus supporting the hypothesis of a continuous reproductive cycle for N. schmitti in the region. Such information is fundamental for understanding the reproductive biology of these crustaceans, as well as other caridean shrimps, in order to promote the maintenance and preservation of natural stocks.

Abstract This study aimed to characterize the population dynamics of Hyalella bonariensis Bond-Buckup, Araujo & Santos, 2008 from headwater spring in a rural area of state of Rio Grande do Sul, Brazil. Four samples were collected in August (winter) and October (spring) of 2012 and January (summer) and April (autumn) of 2013. Ovigerous females and precopula pairs were separated from other individual in the field. A total of 5,266 specimens were sampled, being 1,878 males, 2,073 females (including 240 ovigerous females) and 1,315 juveniles. The frequency distribution of size classes (measured as cephalothorax length, CL) was polymodal and bimodal in males and females, respectively. Males reach larger size than females. Sexual maturity of males and females was estimated at 0.40 and 0.38 mm for CL, respectively. Total sex ratio favored females, and these were more frequent in intermediate size classes, while males were more frequent in larger size classes. Ovigerous females and couples were found in four seasons, but both were more abundant in winter. Juveniles were also found in all seasons, being more frequent in winter and spring. These results showed that this H. bonariensis population has similar dynamics to other species of Hyalella Smith, 1874 from Brazil, but present variations when compared to other freshwater amphipods.

Abstract The reproductive aspects of populations are important determinants of their ability to maintain themselves throughout time. In the case of amphipods from the genus Hyalella Smith, 1874, the reproductive period is easily determined by the presence of ovigerous females and pre-copula pairs in the population. This study evaluated the fecundity, pairing patterns and reproduction period of Hyalella carstica Bastos-Pereira and Bueno, 2012 in a karst environment in the West of Minas Gerais, Brazil. Monthly, from April, 2010 to April, 2011, amphipods were sampled using a hand net with 15 cm diameter and 250 µm mesh size. In the laboratory, animals were sexed and measured, and the ovigerous state of females was evaluated. Couples in pre-copula and ovigerous females were found throughout the year, with the exception of the dry months (September−November). During drought, the stream's superficial water dried out, and only a few refuges for the population remained. Although couples were found in all months with a water flow, a higher number of unpaired males and females was found after the dry season. In all months, ovigerous females were more abundant than non-ovigerous, and the relationship between head length and the number of eggs in the marsupium was positive. Most eggs were in the first developmental stage, although all other stages were found before the dry season. Considering the frequency of pre-copula pairs, as well as ovigerous females, the reproduction in this H. carstica population seems to be continuous throughout the year, without a distinct peak.

To the present 57 species of Hyalella were described for Americas, 15 of them found in Brazil, which is among the most diverse countries for this genus. This work aims to describe a new Hyalella species with benthic habits which is found in a water source on Southeastern Brazil. It is mainly characterized by a wide truncated process formed near the dactylus insertion on gnathopod 2, besides both coxal and sternall gills present on pereonits 2 to 7. This work improves the knowledge on biodiversity about Hyalella species.

The genus Hyalella Smith, 1874 is typical from the continental American waters and show high levels of endemicity. In Brazil, the occurrence of 12 species was reported, of which only Hyalella caeca Pereira 1989 is troglobiotic. A new species was found in a cave, Gruta da Toca, located near Itirapina city, state of São Paulo, Brazil. This species represents the second troglobiotic for the genus in Brazil.
