This retrospective study shows the profile of arachnidism, ophidism, and scorpionism in the Ouro Preto Municipality, Brazil, from January 2007 to December 2013. The data were gathered from forms of the Epidemiological Surveillance Sector of the town's Health's Municipal Secretary. Of the 412 envenomations, 308 were caused by spiders, 78 by scorpions, and 26 by snakes. The highest number of incidents involved people aged 20-34 years. Females were more affected than males. There were no reports of death. The results show that envenomations caused by spiders, scorpions and snakes have decreased in recent years.

Scorpions, especially in urban areas, due to the great demographic density and confrontation possibility, represent a risk to the public health. Tityus serrulatus is the most important species, causing the highest number of accidents. This study intended to raise epidemic data and the occurrence of scorpionism in Belo Horizonte, between 1990 and 1997. The data were gathered from the records of Hospital de Pronto Socorro João XXIII. Of the 3265 cases, most occurred in 1996, of which six were fatal accidents. With greater incidence in January, the male sex, superior members and 25-65 year-old age group were the most affected. The results constitute an important tool for the control of scorpionism, since they delimit the areas most involved and the victims' profile, enabling more efficient and durable prevention educational campaigns.

A velocidade do vôo das borboletas tem sido relacionada à sua palatabilidade; espécies palatáveis costumam apresentar velocidades de vôo maiores que espécies impalatáveis. Este estudo teve como objetivo avaliar o padrão de vôo de espécies de borboletas frugívoras, relacionando os resultados com sua palatabilidade. O estudo foi conduzido em setembro de 2007, no Parque Natural Municipal Chácara do Lessa, em Sabará, MG. Borboletas foram capturadas com redes entomológicas, identificadas e parâmetros biológicos como o desgaste alar, tipo de vôo, palatabilidade, velocidade de vôo e sexo foram anotados. Foram capturados 45 indivíduos, distribuídos em nove espécies de borboletas, todas palatáveis. Machos foram mais capturados que fêmeas; o tipo de vôo mais registrado foi o rápido e circular, a maioria das borboletas voou entre 2,1 e 3m, o ambiente com o maior número de capturas foi o ecótone e as velocidades variaram entre 0,86 e 2,07 m/s. Nenhum parâmetro biológico avaliado correlacionou-se com a palatabilidade das espécies. Padrões de vôo diferentes foram observados dentro de uma mesma espécie, sugerindo que a individualidade pode estar envolvida na resposta apresentada pelas espécies aos seus predadores.
PALAVRAS-CHAVE: Borboleta, palatabilidade, comportamento de vôo, desgaste alar, frugívoras.

To investigate the science of animal welfare for zoo and wild animals in the period from 1966 to 2007, we conducted a bibliometric analysis of abstracts downloaded from The Web of Science© database using the keyword combination “Animal welfare, Zoo* and wild” in the topic field. In total we downloaded 1,125 abstracts, which were classified into the following categories: year of publication; environment of the study (e.g., zoo) or theoretical; area of knowledge (e.g., conservation in situ); number of experimental animals used; species; addresses of authors; taxonomic classification; publication language; journal name; number of citations received. Since 1990, there has been a rapid increase in the number of articles published in this area of animal welfare. One worrying result was that published articles were predominately of a theoretical nature (58.65%, N=563). Most of the articles were published by authors either in Europe (47.43%, N=480) or North America (37.65%, N=381) and written in English (87.71%, N=971). The majority of experimental studies were conducted with mammals (75.92%, N=391), and had small sample sizes (N=7 for zoo-based studies). In terms of impact factor (IF), the journals in this study had a median factor equivalent to that for the area of biological sciences (median IF=1.013). Little knowledge cross-over from farm animal welfare was found (only four articles) in this study. In conclusion, zoo and wild animal welfare as a science may benefit from a greater interaction with farm animal welfare. Zoo Biol 28:561–573, 2009. © 2009 Wiley-Liss, Inc.

GAP analyses are tools used to inform us about the short-comings of a scientific area or necessities in social–economic problems. In the last 20 years, environmental enrichment as an area of scientific investigation has come of age; this can be clearly seen by the number of publications produced in this area. For example, a search on the database The Web of Science©, using the keywords “environmental enrichment”, from 1985 to 2004 produced 744 articles. In this study we analysed these 744 articles and classified them by year into: type of environment (e.g., zoo, farm and laboratory); taxonomic classification (e.g., mammal, bird, etc.); type of enrichment (e.g., food, sensory, etc.); subject area (e.g., neurosciences and agriculture); country of publication; and gathered data on experimental design (e.g., sample sizes). Furthermore, we collected similar data on animal well-being and animal conservation for comparative purposes (keywords: “animal well-being” and “animal conservation”). The results from this study show that the number of environmental enrichment studies has been steadily increasing from a low level in the 1980s until 1999, when there was a noticeable acceleration in the number of articles published. Largely, this acceleration was a response to the growing interest in environmental enrichment by neuroscientists. The data also show a relative lack of, and recent decline in, publications in the area of agriculture. Thus, the data suggest a need for more research on enriching the lives of farm animals. Environmental enrichment publications over the 20 years of the study corresponded to 27% of all animal well-being publications in the period. One interesting comparison between enrichment and animal well-being revealed the virtual absence of research in animal well-being by neuroscientists. The detailed results of this study will help in identifying gaps in our knowledge about environmental enrichment, and how experimental designs might be improved.

It is widely known that the adverse effects of stress must be considered in animal conservation programmes. However, a full consideration of how and where stress occurs in animal conservation programmes has not been undertaken, especially in translocation and reintroduction programmes. The literature concerning these types of programmes shows high levels of mortality, despite researchers' consideration of the effects of stress. However, an analysis of the literature shows that many conservation biologists have only a superficial knowledge about stress. For example, most do not understand the importance of subclinical stress or the fact that the effect of successive stressors can be additive or accumulative. While most conservation biologists know that stress is bad for animal health, few have considered its adverse effects on cognitive abilities, which an animal needs to survive in the wild (e.g. memory). In this paper we conclude with suggestions for improving the efficiency of animal conservation programmes in terms of the number of animals surviving after reintroduction or translocation. The most important conclusion from this review of the literature is that there needs to be a greater interchange of information between animal welfare and animal conservation scientists.
