Estrutura genética populacional de Heliconius erato e Heliconius melpomene (Lepidoptera: Nymphalidae) em fragmentos de Mata Atlântica do Rio Grande do Norte

Extensive studies using molecular markers on butterflies have shown how a highly fragmented landscape may result in the reduction of gene flow among patches of habitat and, consequently, increase genetic differentiation among populations. However, little is known about Heliconius geographical structure and the effects of fragmentation on the connectivity of populations. Furthermore, findings on the effects of the population structure on the dynamics of mimicry evolution in Heliconius butterflies need to be tested in H. erato and H. melpomene specimens found in other locations other than Central and northern South Americas. For the present study, we had two motivations: (1) compare the population structure of H. erato and H. melpomene given the highly fragmented Brazil s Atlantic Forest habitat; and (2) studying population structure of co-mimics could give us insights into the dynamics of mimicry evolution. For this, we analysed the spatial structure and connectivity of eight populations of Heliconius butterflies, in a total of 137 H. erato specimens and 145 H. melpomene specimens, using nine microsatellites loci, 1144 AFLPs markers and 282 mitochondrial DNA sequences. In general, both species exhibited evidence of population subdivision but no isolation by distance indicating some extent of genetic differentiation among populations. Contrary to Kronforst & Gilbert s (2008) Costa Rican Heliconius, H. melpomene exhibited more genetic differentiation than H. erato based on nuclear markers. However, for mitochondrial DNA, H. erato populations showed more genetic differentiation than H. melpomene. Our results corroborate to other studies on Heliconius butterflies concerning the pronounced population subdivision and local genetic drift found in this genus. Nevertheless, the pattern of this differentiation varies significantly from the pattern found in studies conducted in Central America, where H. erato is generally more differentiated and structured than H. melpomene, based on nuclear markers. This different pattern may reflect different evolutionary histories of Heliconius species in Northeastern Brazil s Atlantic Forest

Análise dos remanescentes de mata atlântica do Estado do Rio Grande do Norte : uma perspectiva em alta resolução

The habitat loss and fragmentation are considered the main threats to the biodiversity. These threats operate at the landscape level, which drives the need to manage entire landscapes, not just its components. Although systematic monitoring of the Atlantic Forest biome has been ongoing since the late eighties, current data on forest fragmentation for the sub-region of Pernambuco are practically nonexistent. This study aimed to map out, with high spatial resolution, the remnants of Atlantic forest in Rio Grande do Norte, and conduct a landscape level analysis. The results show that the landscape is highly fragmented, where about 13.6% to 17% of biome remains. Most of the fragments is less than 10 ha, while a few fragments have area larger than 100 ha. Although the high degree of fragmentation, the average distance between fragments found was small (128 m), this estimate is lower than has been observed for the biome (1440m). There is evidence that abrupt changes in the quantification of landscape structure can occur when one observes the fragmentation at high spatial resolution. The results presented here can be used in management actions, in order to make the scenario more conducive to maintaining biodiversity.

Movimento de borboletas frugívoras e conectividade funcional em uma paisagem de Mata Atlântica

An organisms movement within and between habitats is an essential trait of life history, one that shapes population dynamics, communities and ecosystems in space and time. Since the ability to perceive and react to specific conditions varies greatly between organisms, different movement patterns are generated. These, in turn, will reflect the way species persist in the original habitat and surrounding patches. This study evaluated patterns of movement of frugivorous butterflies in order to estimate the connectivity of a landscape mosaic in an area of Atlantic Forest. For this purpose, we used the capture-mark-recapture method on butterflies trapped with fermented fruit bait in three distinct habitats. The first represents a typical Atlantic forest fragment, while the other two represent man-made matrix habitats. One contains a coconut plantation and the other a plantation of the exotic Acacia mangium species. Five traps were randomly placed in each landscape unit in areas of 40 x 40m. Using recapture data and relating it to distance between captures and habitat structure, I found that movement frequencies, both within and between landscape units were different for the analyzed species, suggesting that they do not interpret and react to the landscape in the same way. Thus this study was able to measure landscape functional connectivity. For most species, the exchange between forest and coconut plantations occurred with low frequency compared to exchanges between the forest and acacia plantations, which share more structural similarities. This seems to indicate that a matrix that is more similar to patches of native vegetation can shelter species, permit their movement and, consequently, contribute to the landscape connectivity

O discurso formativo do Biólogo sobre a morte: matizes e metáforas do saber que o sujeito não deseja saber

This study - Biologist s formative speech about death. Nuances and metaphors from knowing that the subject of do not want to know - shows a marginal cognitive construction in scientific education from biologist - death. It considered as obvious that death is a theme that covers both the scientific education from biologist and the division of the subject, and concerns the splitting of the double life-death and the principles of inclusion and exclusion of the subject. Part of sensitive question: What is the epistemological weave who supports biologist's speech about death? It is constituted an object of study of the biologist s speech on death. It is advocated the thesis that: Death is an epistemological obstacle announcing for something always aims to escape from the perspective of knowledge, especially of scientific knowledge because, since it is understood as cognitive learning about the disruption of biological phenomenon life which is involved on weave of imaginary and symbolic constructions about the finiteness of life; it has constituted a metaphorical knowing - encouraged by the noisy silence - which does not allow to know in full, mobilizing hence subject in searching for transitional truths that reduce the ontological being-mortal anguish centered in subjective dimension involved in the act of knowing. From this movement of search that the object mental life after death wins a symbolic value that requires a real-looking multi-referential for the study of biology - life - and its implications: the finiteness of life, especially by moving the omnipotence of scientific objectivity expressed by signs and symbols that seek say the completeness of scientific knowledge-, signaling thus the existence of the dynamics of incompleteness implicit in subjectivity that supports knowledge relating to the double, life and death, and to the temporality of the existence of Homo sapiens sapiens, with the axis guiding the desire of the subject, do not want to know about death, implicit in the mechanisms objective-subjective founded by non-said of death is the epistemology of the existence of objective-subjective subject, whose core is the negation of death. The theoretical methodological knowing web is anchored in the multi-reference which favors a transit by theoretical current, as the Psychoanalysis, bachelardian philosophy, the epistemology of complexity, the Thanatology, the Social Psychology, and Etnocenology, and Understanding Interview. The unveiling of the study object from the analysis of oral speech of eleven biologists who serve in high school, from three main guiding: Death in the history of life,Death in biologist s academic education and, Conceptions about concepts

Políticas públicas de atendimento à criança: desafio da ação articulada no Projeto Belém Criança (2001-2004)

Public politics of Service to the Child: The Challenge of the Action Articulated in the Project Belém Criança (2001-2004) if it constitutes in a study on the politics directed toward the children of 0 the 6 years. It has as objective to analyze the configuration of the politics of integral attention to the child, evidencing the form as the same ones they had been redimensioned by the neoliberal ideas and by the lines of direction of the international organisms. The work has like empiric reference the project Belém Criança, developed by county of Belém from a partnership with the Deep of United Nations for Infancy (UNICEF), in the period of 2001 and 2004. The project intends to develop an articulated action among the several county departments which offer assistance to the children looking for to rationalize the resources and to optimize the services. Amongst the methodological procedures that materialized the research distinguished: The bibliographical review and documental allowed to analyze the contextualization of the public politics and, between them, the social politics of attendance to the child; the historical revolution this attendance; the paper of the UNICEF how articulator of the politics in municipal scope; and the paper of county how executer these politics. Still it was utilized, the half-structuralized interview, Having like subjects: the representative of the UNICEF in Belém, the municipal co-managers and actors of community in which the project was implemented. The result of the analyzes review that, historically, the politics destined to the child they had been being dimensioned having like support the fight of social movements vindictive for publics politic which guarantee the fundamentals rights these citizen. Although legal dimension of current politics of attendance to the child, to assume a vision of completeness and the guarantee of the rights, it still has a great exaggeration between the speech and the practical one. Actually, the same one are elaborate inside the neoliberal optics, with ruled actions by the beginning in combat to the poverty, implanted with low costs and with practice which to lead to the excessive fragmentation, generating inadequate actions and punctual programs which don t guarantee the social quality of the attendance. This perspective was evidenced to the most of the actors which the Project Belém Criança don t constitute itself a real public politic toward the child of 0 the 6 years, although present innovating aspects, how the mobilization and participation. It was demonstrated yet, in the participant s depositions of the research, that the bureau had numberless of difficulty to develop the action preview in the project, it has seen the great complexity of articulation between the several organism responsible by politics of attendance

As ciências da educação e a prática: sentidos atribuídos por estudantes do curso de Pedagogia

This study focuses on the initial formation of the pedagogue in college, especially the formation that takes place in the Pedagogy Course. It is bound by the following question: what senses are attributed by the Pedagogy Trainees regarding the relation between the Education Science knowledge and the Pedagogic Practice knowledge developed in the Pedagogy Course of UESB, in order to build up teaching knowledge and practice? Therefore it aims to reflect on the relations between the Education Science framework and the Pedagogic Practice under the supervised classes that belong to the Pedagogy Course. It presents the implications and contextualizations concerning the pedagogue formation as a historic and cultural process, emphasizing the current moment of this formation. It is based on the idea that the senses trainees, future pedagogues, attribute to their own formation process reflect on the learning of theorical and practical knowledge that validates the process of teachers formation, especially the pedagogue formation. Accordingly, it believes that the senses attributed by the students of teachers initial formation courses regarding the Education Science knowledge and Pedagogic Practice knowledge are essential as organizers in the construction of teaching knowledge and practice while the supervised classes take place. The theorical and methodological option is based on the studies of Qualitative Epistemology by Gonzalez Rey. Empiric studies took place at the Pedagogy Course of Universidade Estadual do Sudoeste da Bahia (UESB), located in the city of Vitória da Conquista/Bahia. The students who took part in this research were six graduating ones, enrolled in the last two semesters of the referred course, stage when the supervised classes happen. The procedures used in the organization of collected information consist of analysis of documents such as the mentioned course curricular project and the students reports, besides interactive and provocative talks to the students. The results show the senses students attribute to Educational Science theorical basis to practice to Pedagogic Practice opportunity of feeling as if they were teachers and to the relation between Education Science and Pedagogic Practice opportunity of experiencing the relation between theory and practice. Besides, the theorizations students have about the relation between theory and practice in teachers formation are also presented. Consequently, it is emphasized that the supervised classes are the moments in which the trainees might understand the relations between thought and pedagogic practice, building the senses attributed to the relation between the Education Science knowledge and the ones of Pedagogic Practice as organizers in the teaching knowledge and practice. In this context, the trainees build some knowledge regarding what it means to be a teacher, which is not written or published, due to its subjective dimension, but circumscribed in their pedagogic practice while the supervised classes take place and when professional teaching practice becomes effective

Apoio pedagógico, ação coletiva e diálogo: tramas da formação continuada em educação inclusiva

This work detaches the importance of the continued formation of the educators in terms of the inclusive educational process, pointing as basic elements the continued formation of the educational professionals. In this direction, it points and it defends the dialogue in the perspective of David Bohm, with interfaces of the freireanas ideas, as a methodological resource of action that allows the organization of strategies of collective and effective pedagogical support in inclusive schools, in the same time articulates the continued formation of the professionals in education. Characterized as research in a dialogical action with collective participation and collaboration, it counted with the participation of 87 educators, between professors, pedagogical, managing coordinators and specialists of special education in two schools of the state and municipal public system of Natal/RN. The results had pointed with respect to the viability of the dialogue as articulated methodological tool of the continued formation in service, when providing the establishment of personal and professional relationship between the educators, favoring the discursive enjoyment of the lived experiences, allows the organization of strategies of collective and effective pedagogical support in the scholar environment. On the basis of these results, this work also points to some items to reflections as the reorganization of the Secretariats and the schools, in the direction to brighten up the fragmentation and the discontinuity of the pedagogical actions evidenced and to instigate a process of changes that has glimpsed the professional development of the educators through its continued formation in service and the improvement of the school in the way of the concretization of an education directed toward the acceptance, respect and attendance the diversity of its pupils, as detaches the official documents and the studies on the inclusive education

O(s) saber(es) e o(s) fazer(es) do professor formador :reflexões sobre a prática docente

This study, developed in conjunction to the Pedagogical Practice research line and the Curriculum of Post-graduation in Education Program of UFRN is about investigations on formation of professors and teaching knowledge. Its objective is to analyze fundamental concepts for lecturing and the relationship that establishes between those concepts and the practice of forming professors. We adopted as referential the principles of social-historical approach, in the context of concepts making and development (Vygotsky, Luria and Rubinstein), and of collaborative theoric-methodological approach (Jacullo-Noto, Kemmis and Ibiapina). Collaboration with professors was mediated by diary writing, collaborative observation and conceptual network creation, essential to perceiving the given meanings to concepts that sustain the practice of 06 (six) forming professors from the UFPI Pedagogy Course. Teresina Campus. This way, reflections with collaborator professors allowed to build conceptual networks, in which prominence was given to the meanings of concepts that gave sustaining to their lecturing practices in the referred course, showing a fragmentation and disarticulation between theory and forming practice. They also indicate a need to give new concepts to the meanings of teaching concepts, learning and lecturing of these professors, in a meaning of a greater understanding about those concepts for their effective practice. On the context of collaborative reflection about conceptual networks, it was evident the conflict generated between the meanings attributed by professors and the practice developed in class, pointing to the need of rethinking the articulation between theory and practice not only on the formative process developed, but also on the continual formation of forming professors and on the construction of discussing spaces and materialization of the curricular principles of the Pedagogy Course

Sensibilidade interoceptiva e respostas psicofisiológicas ao exercício submaximo

The complex human behavior related to exercise involves cognitive, physical and emotional processing. The recent theories about exercise s intensity regulation have highlighted the role played by psychophysics aspects in controlling exercise s intensity. In this regard, recent evidences have shown that there is variability in human capacity in perceiving interoceptives clues. Thus, subjects more sensitive show higher physiological arousal to physical and/or emotional stress, and sensations with higher intensity. In fact, studies have evidenced that interoceptive feedback modifies behavior in exercise with free load. However, exercise recommendations are based in a constant load standard. Therefore, we aimed to analyze the influence of interoceptive sensibility on psychophysics responses during dynamic exercise performed with constant load. Twenty-four adult males were allocated into two groups accordingly with their interoceptive sensibility: high sensibility (n=11) and low sensibility (13). They underwent to an incremental test (IT) and then randomly to two sections of moderate and severe exercise intensity for 20 minutes. Heart rate (HR), rating of perceived exertion (RPE), affective feelings (AF), alert state (AS), and percentage of associative thoughts were collect during exercise. A two-way ANOVA with repeated measures was used to assess differences between psychophysics responses. There were differences between group in RPE, AF, and AS in moderate intensity. There was no difference in any measure in severe intensity. We conclude that subjects with high interoceptive sensibility feel dynamic moderate exercise more intense than the subjecs with low interoceptive sensibility

Vivências de familiares do paciente internado em unidade de terapia intensiva: estudo fenomenológico

This study originated from my concerns as critical care nurse, regarding the lived experience of the family member of the patient that is hospitalized in the intensive care unit - ICU. The purpose of the study was to comprehend the experience of the family members while having a loved one interned in an ICU, and to identify the common elements of the phenomenon, based on the descriptions of their experiences. Considering that the object of study involves subjective and social questions, the study was conducted using some fundamental ideas of descriptive phenomenology as a referential and the situated phenomenon as suggested by Martins and Bicudo (1989). Ten (10) family members of patients that were interned in the ICU of private hospital in Natal, RN were interviewed using the following leading question: What is it like to have a member of your family interned in the ICU? Five thematic structural categories emerged from the comprehensive analysis of the interviews: Fear of the family member s death; Lack of humanization; Social isolation; Confidence in the ICU; and Overload to the personal life. The description of the phenomenon enabled a new look at how the care team relates to the family members of the patients interned in the ICU, providing some guidance on how to construct a humanized care that involves the family and that is based on affective human relations. This involves a rethinking of the care provided by team to the family and stimulates the reformulation of personal and social attitudes, and of hospital organizational norms

Atuação de técnicos de enfermagem junto ao recém-nascido com dor em uma unidade de terapia intensiva neonatal

The pain is a sensuous and emotional experience unpleasant associated or related to real injury or potencial of the tissues. It is considered an individual and subjective experience generally has been described in the literature about in the neonatal stage a lot. This study has descriptive and exploratory character with a qualitative approach. The study has with objectives to analyze the performance of the nursing technicians working with newborns admitted in the ITUN, seeking to describe the perception of the nursing technicians about the pain, identify the parameters used for the detection and evaluation of pain in them, trying to describe the ons of this team about the pain in the newborns in ITUN. The subjects are nine nursing technicians of the ITU of the Parenting School Januário Cicco in Natal-RN, engaged in direct assistance to newborns in the ITU, on the turn of the morning, which was prepared to participate in the search. The collection of the data was conducted through a structured interview with tree questions; through a non-participatory observation with a structured roadmap and were used to record and pass on call was also as a way of obtaining data. The start of the collection made after the assent of the Ethics Committee / UFRN in November, 2007. The speakings have been transcribed and data read extensively to obtain categories.The analysis of the content made in terms of Bardin. Emerged three main categories of significance: Perceptioning of pain in newborns; Caring for the newborns with pain; Registering the pain in the newborns. A nursing technicians identifies the pain in the newborns, for the most part, so empirical, using signs of behavioral or physiological changes in isolation, giving little emphasis to the environment and to respect that the newborns is inserted. It was found that the attitudes cited by subjects of the search before the newborns with pain, are for the most part non-pharmacological actions such as sucking nutrient not, a proper positioning and measures of comfort, however pharmacological actions have also been reported.These is also the absence of records of nursing records in the report of pain and actions to minimize them and, in records and for the passage of call. With this study we understand the role of the nursing technicians, and seek to contribute to subsidies for the practice of professionals involved in caring for this age group, and also in the search for a humane assistance to the newborns

O projeto politico pedagógico de enfermagem e o sistema único de saúde: a visão de discentes

This research aims to analyze, in the view of students, the pedagogic project of undergraduate nursing course, of UFRN, and its articulation with the SUS, in an attempt to understand the issues that permeate the teaching and learning of nursing. This is a qualitative study that used the focus group technique as a tool to collect empirical data. There were three meetings, where we had the collaboration of 23 graduating students from the eighth period of the semester 2009.1. For the analysis of information, we use a theoretical framework based on curriculum guidelines and basic principles of the SUS, making the analogy of the results with the metaphor of Greek mythology, Ariadne's thread, in dialogue with authors who discuss education as a transformative practice. Thus, the texture of the yarn was built of five thematic fields: joint the pedagogic project with the SUS; the teaching/service and theory/practice relation; interdisciplinarity or transdisciplinarity; didactic/methodological and relational approaches; and co-participation of students in the pedagogic project. According to the discussions, we find many difficulties in the teaching and learning process of undergraduate nursing in UFRN to strengthen the SUS, including: dislocation of educational institutions with services, professionals, managers and community; dichotomy between theory and practice; reality of services as a learning field and working process in health; posture adopted by professionals, teachers and other subjects included in the process of health education; decontextualization and fragmentation of teaching with the practice in health and nursing; excessive use of very illustrative methodologies, but little problem-solving; difficult and precarious situation in the relations between teachers and between teachers/students, regarding the acceptance of differences; absence of participation of students in the evaluation process and conduct of the educational project in progress. In this sense, we understand the need an auto-reflexive act of teaching and conducting collective pedagogical course with a view to achieving the SUS. Thus, it is necessary to support practices motivated by the polyphonic dialogue and the exercise of symbiosis and autopoiesis of subjects/actors jointly responsible for the ongoing process of learning for life.

Identificação de crianças e adolescentes com suspeita de câncer: uma proposta de intervenção

Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte
