Research has demonstrated that policing is a stressful occupation and that this stress has a negative impact on police officers' mental and physical health, performance, and interactions with citizens. Mental health at the workplace has become a concern due to the costs of depression, anxiety, burnout, and even suicide, which is high among police officers. To ameliorate occupational health, it is therefore crucial to identify stress and burnout levels on a regular basis. However, the instruments frequently used to measure stress have not valorized the specificity of policing tasks. This study aims to: (i) conduct a literature review to identify questionnaires used to assess occupational stress and burnout among police officers; (ii) analyze the psychometric characteristics of a Portuguese version of Operational Police Stress Questionnaire (PSQ-Op); and, using the PSQ-Op and other questionnaires, (iii) to identify operational stress, burnout, and distress levels among Portuguese police officers. The literature review identified 108 studies which use a multiplicity of questionnaires to measure burnout or occupational stress among police officers, but few studies use specific police stress questionnaires. Sample sizes were mostly below 500 participants and studies were mainly developed in the last decade in the USA and Brazil, but also in another 24 countries, showing the extent of the interest in this topic. This study applied to 2057 police officers from the National Portuguese Police, a force policing urban centers, and used the PSQ-Op, as well the Spanish Burnout Inventory and the Kessler Psychological Distress Scale. The results show that the psychometric properties of the Portuguese version of PSQ-Op are adequate. Factorial analysis revealed two dimensions defined as social and work issues, which were associated with measures of distress and burnout. Fit indices suggested a second-order solution called operational police stress. Overall, and considering the scale range of each questionnaire, the results showed moderate values of operational stress, distress, and burnout. However, considering their cutoff points, 85% of the sample presented high operational stress levels, 11% critical values for burnout, and 28% high distress levels, with 55% of the sample at risk of a psychological disorder. These results reinforce the need to prevent stress and to invest in police officers' occupational health.

This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. ( M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies.

Este estudo foi realizado no Parque Nacional de Superagüi (PNS) e na Reserva Particular do Patrimônio Natural de Volta Velha (RPPN), ambas áreas de Mata Atlântica, nos Estados do Paraná e Santa Catarina, no sul do Brasil. Morcegos foram capturados em redes de neblina e amostras fecais foram coletadas para análise da dieta. As sementes encontradas em cada amostra foram identificadas em laboratório por meio de lupa. Cento e trinta e sete exemplares de Artibeus lituratus (Olfers, 1818) foram capturados (n = 47 no PNS, n = 90 na RPPN), e 25 e 32 amostras fecais foram coletadas para cada área, respectivamente. A dieta frugívora de A. lituratus computou de 81 a 88% do total dos itens alimentares, mostrando a importância dos frutos para esta espécie.

Policing is a stressful occupation, which impairs police officers’ physical/mental health and elicits burnout, aggressive behaviors and suicide. Resilience and coping facilitate the management of job stress policing, which can be operational or organizational. All these constructs are associated, and they must be assessed by instruments sensitive to policing idiosyncrasies. This study aims to identify operational and organizational stress, burnout, resilient coping and coping strategies among police officers, as well to analyze the psychometric properties of a Portuguese version of the Organizational Police Stress Questionnaire. A cross-sectional study, with online questionnaires, collected data of 1131 police officers. With principal components and confirmatory factor analysis, PSQ-org revealed adequate psychometric properties, despite the exclusion of four items, and revealed a structure with two factors (poor management and lack of resources, and responsibilities and burden). Considering cut-off points, 88.4% police officers presented high operational stress, 87.2% high organizational stress, 10.9% critical values for burnout and 53.8% low resilient coping, preferring task-orientated than emotion and avoidance coping. Some differences were found according to gender, age and job experience. Job stress and burnout correlated negatively with resilient coping, enthusiasm towards job and task-orientated coping. Results reinforce the importance to invest on police officers’ occupational health.

ABSTRACT. Bats from southern Brazil: comparative analysis of species richness, new records and nomenclatural update (Mammalia, Chiroptera). A comparative analysis of the patterns of bat species richness in southern Brazil is presented, as well as similarity analyses among states. The highest richness of bat species is found in the state of Paraná, with 64 species, followed by Santa Catarina with 46, and Rio Grande do Sul, with 40. The family Phyllostomidae plays an important role in determining this pattern. The geographical distributions of Trachops cirrhosus (Spix, 1823), Artibeus cinereus (Gervais, 1851) and Thyroptera tricolor Spix, 1823 are expanded to the state of Paraná, establishing a new southern limit for these species and for Thyropteridae. In addition Myotis dinellii Thomas, 1901 is first recorded in Brazil, in Santa Catarina and Rio Grande do Sul, establishing a new eastern limit for this species. The distribution of Eptesicus taddeii Miranda, Bernardi & Passos, 2006 is extended by a new record in Rio Grande do Sul. An updated list of bats for the southern Brazilian states is presented with few nomenclatural adjustments. The importance of more intensive field efforts to survey the chiropterofauna is highlighted as a way to improve conservation efforts based on representative surveys and scientific collections.

A primeira ocorrência de Histiotus montanus (Philippi & Landbeck, 1861) para o Estado do Paraná é reportada. Um macho adulto foi coletado com rede de neblina (em abrigo de forro de casa) em um remanescente de campo natural no Município de Palmas, no Sul do Paraná. Aspectos morfológicos e alguns aspectos biológicos desta espécie são também mostrados.

Climate underlies species distribution patterns, especially in species where climate limits distributions, such as the phyllostomid bats, which are mostly restricted to the New World tropics. The evolutionary dynamics that shaped phyllostomid climatic niches remain unclear, and a broad phylogenetic perspective is required to uncover their patterns. We used geographical distributions and evolutionary relationships of 130 species, climate data and phylogenetic comparative methods to uncover dynamics of phyllostomid climatic niche evolution. Diversification of climatic niches began early in phyllostomid evolution (~34 Mya), with most changes taking place ~20 Mya. Although most of these bats were found in tropical regions, shifts towards different evolutionary optima were common. Shifts were mostly towards temperate climates, reflecting complexities in phyllostomid evolution highlighted by the probable role of species-specific adaptations to cope with these climates, the influence of palaeoclimatic events, and biogeographical effects related to the evolution and dispersal of clades in the New World. Our results broaden our understanding of the relationships between phyllostomid bats and climate, filling an important gap in knowledge and suggesting a complex evolution in their occupation of the climatic niche space.
