Pela Voz das Mulheres: uma análise da violência doméstica entre mulheres evangélicas atendidas no Núcleo de Defesa e Convivência da Mulher Casa Sofia

Essa dissertação tem por objetivo analisar a partir de uma perspectiva sociológica, um fenômeno social: o da violência doméstica entre mulheres evangélicas. Fenômeno este que nos preocupa profundamente e que, cada vez mais se manifesta. Este é um tema desafiador, que por vezes, em muitos espaços e lugares, inclusive nos religiosos, não inquietam o bastante e nem fomentam uma discussão mais intensa e rigorosa. Será, portanto, pelas vozes das mulheres que buscaremos identificar como as representações de gênero estruturam suas próprias vidas para lidarem com a questão da violência sofrida no espaço que deveria ser o lócus do afeto, do desenvolvimento da confiança, da auto-estima, do acolhimento, da compreensão e respeito, do ninho de amor e que são antagonicamente transformados, principalmente para as mulheres e crianças, no local para o qual gostariam de não voltar. Procuraremos compreender como a religião evangélica, de maneira sutil, simbólica ou de forma concreta, por sua teologia, pela prática pastoral, nos aconselhamentos ou na própria dinâmica da comunidade, trata a violência doméstica contra mulheres, solicitando o silêncio, a submissão, a espera do cumprimento das promessas de Deus em suas vidas: a libertação de seus maridos, companheiros. Uma troca: o silêncio pela promessa de uma família feliz. Invocação de representações sociais para justificarem ou ocultarem práticas violentas contra as mulheres, mas em nome de Deus. Entretanto, o que pensam e o que sentem essas mulheres? Elas realmente gostam de apanhar? São de fato cúmplices da violência sofrida? Por que resistem em denunciarem seus parceiros agressores e não rompem ou demoram tanto tempo para romperem relacionamentos violentos? Em que medida sua inserção religiosa está relacionada com essa situação de violência? Para tentar responder a essas perguntas, escolhemos como campo de pesquisa o Núcleo de Defesa e Convivência da Mulher Casa Sofia, uma ONG que atua com mulheres em situação de violência doméstica e sexual. Ao constatarmos o significativo número de mulheres evangélicas que ali são atendidas, nos propusemos analisar as representações religiosas de gênero e sua relação com a violência doméstica.(AU)

Ecologia e história natural de população Hemidactylus agrius (Squamata: Gekkonidae) em área de Caatinga, com avaliação da distribuição das espécies nativas do gênero no nordeste do Brasil

The genus Hemidactylus Oken, 1817 has cosmopolite distribution, with three species occurring in Brazil, two of them native, H. brasilianus and H. agrius, and one exotic, H. mabouia. Considering the studies about ecology of lizards conducted in the Ecological Station of the Seridó, from 2001 to 2011, this study aimed (1) to re-evaluate the occurrence of the species of Hemidactylus in this ESEC; (2) to analyze ecological and biological aspects of the H. agrius population; and (3) to investigate the current and potential distribution of the native species of the genus in northeastern Brazil, analyzing the suitability of ESEC to this taxon. For the first two objectives, a sampling area consisting of five transects of 200 x 20 m, was inspected in alternating daily shifts for three consecutive days, from August 2012 to August 2013. For the latter objective, occurrence points of H. agrius and H. brasilianus from literature and from the database of Herpetological Collections of the UFRN and the UNICAMP were consulted to build predictive maps via the Maximum Entropy algorithm (MaxEnt). In ESEC Seridó, 62 H. agrius individuals were collected (25 females, 18 males and 19 juveniles), and two neonates were obtained from a communal nest incubated in the laboratory. No record was made for the other two species of the genus. Hemidactylus agrius demonstrated to be a nocturnal species specialized in habitats with rocky outcrops; but this species is generalist regarding microhabitat use. In the population studied, females had an average body length greater than males, and showed higher frequencies of caudal autotomy. Regarding diet, H. agrius is a moderately generalist species that consumes arthropods, especially insect larvae, Isoptera and Araneae; and vertebrates, with a case of cannibalism registered in the population. With respect to seasonal differences, only the number of food items ingested differed between seasons. The diet was similar between sexes, but ontogenetic differences were recorded for the total volume and maximum length of the food items. Significant relationships were found between lizard body/head size measurements and the maximum length of prey consumed. Cases of polydactyly and tail bifurcation were recorded in the population, with frequencies of 1.6% and 3.1%, respectively. In relation xv to the occurrence points of the native species, 27 were identified, 14 for H. agrius and 13 for H. brasilianus. The first species presented restricted distribution, while the second showed a wide distribution. In both models generated, the ESEC Seridó area showed medium to high suitability. The results of this study confirm the absence of H. brasilianus and H. mabouia this ESEC, and reveal H. agrius as a dietary opportunist and cannibal species. Further, the results confirm the distribution patterns shown by native species of Hemidactylus, and point ESEC Seridó as an area of probable occurrence for the species of the genus, the establishing of H. brasilianus and H. mabouia are probably limited by biotic factors, a fact yet little understood

A cafeína como agente modulador do ciclo atividade-repouso e memória em saguis (Callithrix jacchus)

Caffeine is the most consumed psychostimulant, with effects on attention, memory, and arousal. But when this substance is ingested near to bedtime there is a decrease on sleep, interfering on mnemonic processes. So, our ain was to investigate how the caffeine ingested near to sleep onset acts on sleep and memory in marmosets. We used 16 adult marmosets, single housed, in a 12:12h light-dark cycle. For registering locomotor activity were used two kinds of sensors. The gyroscope sensor registers activity each 30 sec and detects motion with good accuracy. Because of this we used this sensor for detecting nocturnal activity. The second sensor was based on infrared and accumulates activity each 5 min and it’s not able to detect nocturnal activity, just diurnal activity. We also used camera for registering Rest phase of one marmoset. For the cognitive task, the animals needed to learn a rewarded context (CR) when compared to a non-rewarded context CNR). This experiment comprises 5 phases: 1) Two days of habituation to apparatus; 2)Training for 8 days; 3) oral administration of caffeine (10 mg/kg) or placebo administration ±1h before sleep onset, for 8 days, with marmosets receiving placebo or caffeine; 4) retraining to apparatus and after that, placebo administration (placebo group-GP), or caffeine administration (with continuous group-GC and acute groupGA); 5) Test, for evaluating learning to CR. The sessions were filmed and each one had 8 min of duration. At 7 am started the habituation, training and test sessions, and at 3:15 pm started retraining. The results for gyroscope sensor showed that there was coincidence of 68,57% with nocturnal register of the cameras. Then, the gyroscope sensors detected nocturnal activity for all experimental groups Moreover, when compared sensor gyroscope with sensor based on infrared, was observed that both sensor presented similarity on patterns of activity curve. When we observed the effects of caffeine on Activity-Rest Cycle in GP, GA and GC, is possible to see that that gyroscope sensors and based on infrared presented only intra group differences. As behavioral results, the marmosets learned to discriminate CR when compared to CNR. Moreover, GP presented deficits on memory recall during the test, and GA increased the memory recall, when both were compared to GP. We concluded that the marmosets were able to learning the cognitive task and that the caffeine ingested near to sleep onset acts modulating memory in these animals. Moreover the gyroscope sensor can be used as alternative tool for investigating nocturnal activity. Then, the utilization of this non-invasive device allows marmosets exhibit their behavior within the laboratory conditions as natural as possible.

Biologia reprodutiva de Mimus gilvus (Aves: Mimidae) em área de restinga no nordeste do Brasil

The thrush beach, Mimus gilvus (Aves: Mimidae) is a passerine widely distributed in Central and South America. In Brazil occurs mainly in the areas of the resting and vegetation near the beach. In southeastern Brazil this species has disappeared, mainly due to urbanization. Many attributes of their reproductive biology are unknown, especially in relation to reproductive success. During the years 2010-2011, 2011-2012 and 2014-2015 were made visits to the area of restinga forest in Centro de Lançamento da Barreira do Inferno (CLBI), located between the cities of Natal and Parnamirim-RN (5 ° 54'S 35 ° 10'W ) where they were made systematic searches to trying describe reproductive biology of the characteristics of M. gilvus, estimate their reproductive success using the Mayfield method, and identify the main factors that influence their reproductive success in environment the resting. For this, forty fifth active nests monitored were used. Only during the breeding season of 2011-2012 and 2014-2015 were made systematic visits to the study area. The reproductive period ranged August to March. Clutch size ranged from two, three and six eggs (n = 22). Broods of two eggs were more common, with an average of eggs laid per nest of 2 ± 0,51 (n = 20 nests). The incubation period was approximately 13 ± 1,9 days (n = 11 nests). The period of stay of the nestlings was approximately 11 ± 1,6 days (n = 9 nests). With approximately 11 days old the nestlings were able to leave the nest. The apparent success was 37,8% and the success estimated by Mayfield method was 26,6%. Predation was the main cause of loss of nests in the study area. The daily survival rates (TDS) were obtained from 0,9593 incubation and 0,9313 for nestling period respectively. Survival estimates for each period was 0,5827 for incubation and 0,4571 for nestling period. The cumulative average rainfall for each month influenced negatively the hatching rates of M. gilvus nests. In addition, the number hatch eggs among the most rainy season (rainy season) and the period of lowest rainfall (dry season) were different. The number of lost nests of M. gilvus was lower in scrubs than cactus, which may account for the largest number of nests of this species found in scrubs. Survival rates in nestling period were lower compared with the incubation period. The fact that the survival rates nests of M. gilvus be lower in the nestling period compared to the incubation period may result from increased activity of adults during this phase of the nest, which in turn would increase predation rates. M. gilvus seems to avoid the rainy season during their reproduction, concentrated most of their nests in periods of low rainfall.

Early post-fledgling survival in a fragmented population of a tropical cooperative breeding passerine

During the last years tropical forest has been a target of intense study especially due to its recent big scale destruction. Although a lot still needs to be explored, we start realizing how negative can the impact of our actions be for the ecosystem. Subsequently, the living community have been developing strategies to overcome this problem avoiding bottlenecks or even extinctions. Cooperative breeding (CB) has been recently pointed out as one of those strategies. CB is a breeding system where more than two individuals raise one brood. In most of the cases, extra individuals are offspring that delay their dispersal and independent breeding what allows them to help their parents raising their siblings in the subsequent breeding season. Such behavior is believed to be due, per example, to the lack of mates or breeding territories (ecological constraints hypothesis), a consequence of habitat fragmentation and/or disturbance. From this point, CB is easily promoted by a higher reproductive success of group vs pairs or single individuals. Accordingly, during this thesis I explore the early post-fledging survival of a cooperative breeding passerine, namely the impact of individual/habitat quality in its survival probability during the dependence period of the chicks. Our study species is the Cabanis’s greenbul (Phyllastrephus cabanisi), a medium-sized, brownish passerine, classified within the Pycnonotidae family. It is found over part of Central Africa in countries such as Angola, Democratic Republic of the Congo, Mozambique and Kenya, inhabiting primary and secondary forests, as well as woodland of various types up to 2700m of altitude. Previous studies have concluded that PC is a facultative cooperative breeder. This study was conducted in Taita Hills (TH) at the Eastern Arc Mountains (EAM), a chain of mountains running from Southeast Kenya to the South of Tanzania. TH comprises an area of 430 ha and has been suffering intense deforestation reflecting 98% forest reduction over the last 200 years. Nowadays its forest is divided in fragments and our study was based in 5of those fragments. We access the post-fledging survival through radio-telemetry. The juvenile survey was done through the breeding females in which transmitters were placed with a leg-loop technique. Ptilochronology is consider to be the study of feather growth bars and has been used to study the nutritional state of a bird. This technique considers that the feather growth rate is positively proportional to the individual capability of ingesting food and to the food availability. This technique is therefore used to infer for individual/habitat quality. Survival was lowest during the first 5 days post-fledging representing 53.3%. During the next 15 days, risk of predation decreased with only 14.3% more deceased individuals. This represents a total of only 33% survived individuals in the end of the 50 days. Our results showed yet a significant positive relationship between flock size and post-fledging survival as well as between ptilochronology values and post-fledgling survival. In practice, these imply that on this population, as bigger the flock, as greater the post fledging survival and that good habitat quality or good BF quality, will lead to a higher juvenile survival rate. We believe that CB is therefore an adaptive behaviour to the lack of mates/breeding territory originated from the mass forest destruction and disturbance. Such results confirms the critical importance of habitat quality in the post-fledging survival and, for the first time, demonstrates how flock size influences the living probability of the juveniles and therefore how it impacts the (local) population dynamics of this species. In my opinion, future research should be focus in disentangle individual and habitat quality from each other and verify which relationship exist between them. Such study will allow us to understand which factor has a stronger influence in the post-fledging survival and therefore redirect our studies in that direction. In order to confirm the negative impact of human disturbance and forest fragmentation, it would be of major relevance to compare the reproductive strategies and reproductive success of populations living in intact forests and disturbed patches.

Ichneumonidae (Hymenoptera) capturados em armadilhas Malaise, em Rio Branco, AC.

A ordem Hymenoptera abriga espécies com hábitos parasitas ou predadores de outros insetos e, ainda, espécies polinizadoras de plantas. Constituem um grupo muito diversificado no que tange aos hábitos alimentares e comportamentais. As vespas parasitoides participam em mais de 50% das cadeias alimentares dos ambientes terrestres. A família Ichneumonidae é uma das maiores entre os Insecta, com aproximadamente 60.000 espécies descritas, sendo cerca de 17.000 na região Neotropical. Embora sua importância seja evidente, estudos da biodiversidade de parasitoides na região amazônica são escassos. Neste sentido, o objetivo deste levantamento foi aumentar o conhecimento sobre a fauna de Ichneumonidae no estado do Acre. Foram instaladas duas armadilhas Malaise (uma na bordadura e outra no interior) em um remanescente florestal, localizado no município de Rio Branco, AC. Semanalmente os frascos coletores, contendo álcool a 90%, eram recolhidos e trocados por novos. O material foi triado em laboratório e os parasitoides identificados em nível de subfamília, sob microscópio estereoscópio. A armadilha localizada na bordadura capturou 133 parasitoides de 13 subfamílias, enquanto a localizada no interior da mata capturou 210, de 15 subfamílias. As principais subfamílias foram Cryptinae e Cremastinae, correspondendo a aproximadamente 75% de todos os parasitoides capturados neste levantamento.

Sample size for monitoring sirex populations and their natural enemies.

A vespa-da-madeira, Sirex noctilio Fabricius (Hymenoptera: Siricidae) foi introduzida no Brasil em 1988 e tornou-se a principal praga dos plantios de pínus. Encontra-se distribuída em aproximadamente 1.000.000 de ha em diferentes níveis populacionais nos Estados do Rio Grande do Sul, Santa Catarina, Paraná, São Paulo e Minas Gerais. O controle da população da vespa-da-madeira é feito principalmente pela utilização do nematoide Deladenus siricidicola Bedding (Nematoda: Neothylenchidae). A avaliação da eficiência dos inimigos naturais é dificultada por não haver um sistema de amostragem apropriado. Este estudo testou o sistema de amostragem hierárquica para definir o tamanho da amostra para monitorar a população de S. noctilio e também a eficiência dos inimigos naturais, a qual mostrou-se adequada.
