Microhabitat choice plays a major role in shaping local patterns of biodiversity. In butterflies, stratification in flight height has an important role in maintaining community diversity. Despite its presumed importance, the role of behavioural shifts in early stages of speciation in response to differences in habitat structure is yet to be established. Here, we investigated variation in flight height behaviour in two closely related Heliconius species, H. erato cyrbia and H. himera, which produce viable hybrids but are isolated across an environmental gradient, spanning lowland wet forest to high-altitude scrub forest. Speciation in this pair is associated with strong assortative mating, but ecological isolation and local adaptation are also considered essential for complete reproductive isolation. We quantified differences in flight height and forest structure across the environmental gradient and tested the importance of resource distribution in explaining flight behaviour. We then used common garden experiments to test whether differences in flight height reflect individual responses to resource distribution or genetically determined shifts in foraging behaviour. We found that the two species fly at different heights in the wild, and demonstrated that this can be explained by differences in the vertical distribution of plant resources. In both the wild and captivity, H. himera choose to fly lower and feed at lower positions, closely mirroring differences in resource availability in the wild. Given expectations that foraging efficiency contributes to survival and reproductive success, we suggest that foraging behaviour may reflect local adaptation to divergent forest structures. Our results highlight the potential role of habitat-dependent divergence in behaviour during the early stages of speciation., (© 2022 British Ecological Society.)

Background: Recantation after child sexual abuse (CSA) disclosure refers to the complete denial of prior reports by a victim. In substantiated cases of CSA, recantation has negative effects on criminal proceedings and the protection of current and future victims. Past studies have identified the socio-family factors and CSA characteristics that are associated with recantation. However, the systematization of these risk factors remains limited., Objective: This study aimed to identify the predictors of recantation using a sample of criminal cases of CSA., Participants and Settings: The sample consisted of 108 criminal cases of CSA with (n = 46) and without recantation (n = 62). All the cases had been judged in a Brazilian court of law between 2010 and 2016., Results: The final logistic regression model consisted of the following five significant predictors of recantation: a lack of support from the caregiver (odds ratio [OR] = 15.90, p < .001), disclosure to a single individual (OR = 13.75, p = .001), parental offending (OR = 12.44, p = .001), a long time interval (i.e., >one week) between disclosure and the reporting of the abuse to the authorities (OR = 8.64, p = .003), and a higher number of formal interviews (OR = 1.50, p = .052)., Conclusions: The present findings underscore not only the effects of socio-family factors and the number of interviews on recantation but also the importance of examining the contexts within which previous disclosures of CSA have been made to the assessment of the risk of recantation., (Copyright © 2021 Elsevier Ltd.

This study investigated the association between exposure to child maltreatment and dating physical violence in the affective-sexual relationship among adolescents (n =397, 14-19 years). A mediation model was conducted to determine whether these associations can be mediated by early maladaptive schemas (EMS), from the Schema Therapy's theoretical approach. Also, it sought to verify the invariant model by gender. The results showed that teen dating violence perpetrators with a history of child maltreatment had significantly higher scores in the perpetration of intimate violence than adolescents with no history of maltreatment. Disconnection and rejection realm schemas were mediators between exposure to child maltreatment and dating physical violence in adolescence, and this model was adequate to females. The clinical implications of these findings were also discussed.

This study evaluated the effects and impact of a multicomponent positive psychology program for health promotion of retirees. A quasi-experimental longitudinal design was used, and the baseline and end of intervention evaluations were analyzed. The intervention consisted of six weekly group sessions for 2 h each. Eighty-eight retirees (females = 72) aged 49-86 (M = 65.66, SD = 7.53) from South Brazil took part in the study, 54 (females = 48) in the experimental group (M = 66.37 years old, SD = 7.42), and 34 (females = 24) waitlist controls (M = 64.53 years old, SD = 7.68). The instruments used were a sociodemographic questionnaire and the Brazilian version of the scales: Interpersonal Reactivity Index; 12-item General Health Questionnaire; Life Orientation Test-Revised;14-item Perceived Stress Scale; Resilience Scale; and Satisfaction with Life Scale. Mixed factorial ANOVA models revealed significant decrease in depression and anxiety symptoms and perceived stress levels, whereas improvement in life satisfaction and resilience was detected in the experimental group at the end of the program. No main effect was found for empathy and optimism. Interaction effects yielded significant difference between groups for measures of empathy, optimism, depression, and anxiety symptoms after the program. There was no significant interaction effect for the other outcome variables. The usefulness and applicability of this model of intervention to aid future health practices and policies are discussed. Contextual issues in the fields of health promotion and disease prevention in Brazil are also problematized.

Adaptive coloration is under conflicting selection pressures: choosing potential mates and warning signaling against visually guided predators. Different elements of the color signal may therefore be tuned by evolution for different functions. We investigated how mimicry in four pairs of Heliconius comimics is potentially seen both from the perspective of butterflies and birds. Visual sensitivities of eight candidate avian predators were predicted through genetic analysis of their opsin genes. Using digital image color analysis, combined with bird and butterfly visual system models, we explored how predators and conspecifics may visualize mimetic patterns. Ultraviolet vision (UVS) birds are able to discriminate between the yellow and white colors of comimics better than violet vision (VS) birds. For Heliconius vision, males and females differ in their ability to discriminate comimics. Female vision and red filtering pigments have a significant effect on the perception of the yellow forewing band and the red ventral forewing pattern. A behavioral experiment showed that UV cues are used in mating behavior; removal of such cues was associated with an increased tendency to approach comimics as compared to conspecifics. We have therefore shown that visual signals can act to both reduce the cost of confusion in courtship and maintain the advantages of mimicry., (© 2018 The Author(s).

1. Birds are considered to be the primary selective agents for warning colouration in butterflies, and select for aposematic mimicry by learning to avoid brightly coloured prey after unpleasant experiences. It has long been thought that bright colouration plays an important role in promoting the avoidance of distasteful prey by birds. 2. The hypothesis that warning colouration facilitates memorability and promotes predator avoidance was tested by means of a field experiment using distasteful model butterflies. Artificial butterflies with a Heliconius colour pattern unknown to local birds were generated using bird vision models, either coloured or achromatic, and hung in tree branches in a tropical forest. Two sequential trials were conducted at each site to test avoidance by naïve and experienced predators. 3. There was a significant reduction in predation in the second trial. Also, coloured models were attacked less than achromatic models. Specifically, coloured butterflies were attacked significantly less in the second trial, but there was no significant decrease in predation on achromatic models. 4. The present results imply an important role for colour in enhancing aversion of aposematic butterflies. It has also been demonstrated that previous experience of distasteful prey can lead to enhanced avoidance in subsequent trials, supporting mimicry theory.

Research into Heliconius butterflies has made a significant contribution to evolutionary biology. Here, we review our understanding of the diversification of these butterflies, covering recent advances and a vast foundation of earlier work. Whereas no single group of organisms can be sufficient for understanding life's diversity, after years of intensive study, research into Heliconius has addressed a wide variety of evolutionary questions. We first discuss evidence for widespread gene flow between Heliconius species and what this reveals about the nature of species. We then address the evolution and diversity of warning patterns, both as the target of selection and with respect to their underlying genetic basis. The identification of major genes involved in mimetic shifts, and homology at these loci between distantly related taxa, has revealed a surprising predictability in the genetic basis of evolution. In the final sections, we consider the evolution of warning patterns, and Heliconius diversity more generally, within a broader context of ecological and sexual selection. We consider how different traits and modes of selection can interact and influence the evolution of reproductive isolation., (© 2015 European Society For Evolutionary Biology.

The purposes of this study were to: (1) Assess child abuse professionals' and nonprofessionals' knowledge of scientific research findings that are relevant to forensic child sexual abuse (CSA) evaluations and (2) describe associations between child abuse professionals' levels of research knowledge and their education and experience. An 18-item multiple-choice test was administered to 188 child abuse professionals and 457 nonprofessionals (undergraduate college students) in Brazil and the United States. The nonprofessionals' average percent correct, M=44%, was not significantly different than what would be expected for random guessing (45%). The professionals' average percent correct, M=55%, was higher than that of nonprofessionals and random guessing (both ps<.001). The average percent correct score for the US-sample psychologists, M=76%, was higher than the average score of the other professionals, M=51%, p<.001. Professionals' educational level, as measured by the highest academic degree obtained, was positively associated with percent correct scores, Spearman's ρ=.46, p<.001. Controlling for educational attainment, professional experience, as measured by the total number of CSA evaluations performed, was weakly associated with percent correct scores, partial r=.15, p=.04. Percent correct scores were low for both nonprofessionals and professionals. Most of the participants in this study were uninformed or misinformed about scientific research findings that are important for conducting optimal forensic CSA evaluations and for making accurate judgments about the validity of sexual abuse allegations., (Copyright © 2014 Elsevier Ltd.

This study investigated the correlations between health-related quality of life and social support in adolescents with type 1 diabetes (T1DM). Participants were 102 adolescents between 12 and 17 years old, who were patients of a healthcare program in the city of Porto Alegre, south of Brazil. Two questionnaires, the KIDSCREEN-52 and the Brazilian version of Social Support Appraisals, were used to evaluate health-related quality of life and social support. Results showed good quality of life and social support levels. Strong correlations were verified between social support and three of the KIDSCREEN-52 dimensions: psychological well-being (r = .63; p < .01); peers and social support (r = .67; p < .01) and school environment (r = .64; p < .01). Analysis of linear regression showed that gender, age and social support are variables associated with health-related quality of life, explaining 52.6% of variance. Results revealed the impact of the disease to young people, and can help to find strategies to improve care in these cases.

Violence is a serious public health problem and notification of incidents is fundamental for epidemic surveillance and for the definition of priorities and public politics of health prevention and promotion. The study sought to characterize the occurrence of domestic violence, sexual and other forms of violence, based on the information of the database of the Information System of Notification of Offences (Sinan), on the records of violence of the city of Belém in the state of Pará, in the period from January 2009 to December 2011. In this period 3,267 notifications were recorded, which represented an increase of 240% in the number of notifications of the year 2009 compared to 2011. In relation to the sex of the victims it was observed that, on average, 83.2% of cases against women and this proportion was similar in all three years analyzed. Sexual violence was the most prevalent with 41.8% of reported cases; followed by psychological violence at 26.3% and physical violence at 24%. The results show that notification is fundamental for understanding the profile of violence and for intervention and elaboration of integrated public politics that promote health and the quality of life in this area of Brazil.

This study investigated associations of contextual variables of risk (stressful events and exposure to community violence), variables of protection (family environment, connectivity to the school and community perceptions) and demographic variables (gender and age) with indicators of psychosocial adjustment (self-esteem, involvement in illegal activities and alcohol use in past month) among adolescents. The participants were 685 students (61.5% girls) aged between 12 and 18 years (M = 15.10, SD = 1.52) of public schools in southern Brazil. They answered a questionnaire with 77 questions and an inventory for assessment of family relationships. Logistic regression analyses indicated that the negative perception of family environment, poor connectivity to the school and exposure to community violence were associated with low self-esteem. Involvement in illegal activities was associated with low connectivity to school, stressful events, exposure to community violence and male sex. Finally, alcohol use/month was associated with negative perception of the community, community violence, stressful events, and particularly at the ages of 15-16 years.

Introduction: Drug use is a social and a public health problem that has been related with antisocial behavior. The aim of this study was to evaluate the relationship between drug use and antisocial behavior among adolescents attending public schools in Brazil., Method: A total of 7,176 adolescents from low-income neighborhoods and public schools aged 14 to 19 years were assessed in five geographical regions in Brazil. Data on biosociodemographic characteristics and on drug use and antisocial behavior were assessed from complete answers to a national survey on risk and protective factors among adolescents., Results: Over 80% of the adolescents who used alcohol and cigarettes were between 14 and 17 years old. The percentage of participants with antisocial behaviors was significantly higher among users of marijuana, cocaine, or crack than among adolescents who were not drug users., Conclusions: Prevention programs aimed at reducing substance use might help to decrease antisocial behaviors.

This paper investigated the occurrence and impact of stressing events for 297 low- income children/adolescents (both sexes; 7-16 years, M =11.22; SD = 2.13) in the city of Porto Alegre. Group 1 (G1) consisted of 142 participants (living with their families) and Group 2 (G2) of 155 institutionalized individuals. All were individually interviewed and answered the Stressing Events Inventory for Children/Adolescents. The most frequent stressing events for the sample were: follow orders given by the parents (85.2%); quarrels with friends (72.9%); death of relatives (71.8%); failure at school (69.2%); and rivalry of siblings (68%). Student's t-test revealed significant difference between groups (p <0,001) regarding the occurrence of stressing events, G2 presented higher scores (M = 26.79; SD = 8.67) than G1 (M = 19.16; SD = 9.37). The events that caused the greatest impact upon the studied group were: death of parents and friends, rape, rejection by relatives and violence. There was no significant difference between sexes (p>0.05). The high frequency and strong impact of stressing events reveal the situation of social and familiar vulnerability, presence of violence and lack of resources in the whole group.
