Resumo O livro didático tem sido um instrumento empregado de maneira quase unânime, mas nem sempre é aproveitado de forma criteriosa no processo de ensino-aprendizagem. O objetivo da pesquisa foi analisar as questões ambientais sobre a Educação Ambiental (EA), as mudanças climáticas, o desmatamento, a poluição do ar e da água nos livros didáticos do 6º ano das escolas municipais e estaduais de Jataí (GO). A metodologia consistiu em Silva (2004) para analisar os conteúdos ambientais nos livros didáticos, considerando os conteúdos abordados, a concepção de natureza, a consistência e as lacunas. Como resultado, o tema EA não é tratado em nenhum dos livros. O livro do município expressa uma visão ambiental nos alunos ao contemplar os temas propostos para a pesquisa. Já no livro do estado, percebe-se que as questões ambientais são discutidas com quantidade insuficiente de atividades, figuras, gráficos e textos contextualizados sobre os impactos ambientais e que estimulem a conscientização dos alunos. Dessa forma, os livros dão apoio para que o professor possa trabalhar suas aulas de forma interativa com os alunos, visando o aprendizado deles, levando-os a uma visão crítica das questões ambientais, considerando as sugestões dadas para abordá-las com maior aprofundamento. Palavras-chave: livro didático, ensino de geografia, Jataí (GO).   Abstract The textbook has been an instrument used almost unanimously, but it is not always used in a judicious way in the teaching-learning process. The objective of the research was to analyze the environmental issues on Environmental Education (EA), climate change, deforestation, air and water pollution in the textbooks of the 6th grade of the municipal and state schools of Jataí (GO). The methodology consisted of Silva (2004) to analyze the environmental contents in the textbooks, considering the contents covered, the conception of nature, the consistency and the gaps. As a result, the EA theme is not covered in any of the books. The book of the municipality expresses an environmental vision in the students when contemplating the themes proposed for the research. In the state textbook, we can see that environmental issues are discussed with insufficient amounts of activities, figures, graphs and texts contextualized on environmental impacts and that stimulate students' awareness. In this way, the books provide support so that the teacher can work his classes in an interactive way with the students, aiming at their learning, taking them to a critical view of environmental issues, considering the suggestions given to approach them with more depth. Keywords: textbook, geography education, Jataí (GO).   Résumée Le manuel a été un instrument utilisé presque à l'unanimité, mais il n'est pas toujours utilisé de manière judicieuse dans le processus d'enseignement-apprentissage. L'objectif de la recherche était d'analyser les questions environnementales sur l'éducation environnementale (EE), les changements climatiques, la déforestation, la pollution de l'air et de l'eau dans les manuels scolaires de la 6e année des écoles publiques et municipales de Jataí (GO). La méthodologie a consisté à Silva (2004) pour analyser le contenu de l'environnement dans les manuels scolaires, compte tenu du contenu couvert, le concept de la nature, la cohérence et les lacunes. Par conséquent, le thème EA n'est couvert dans aucun livre. Le livre de la municipalité exprime une vision environnementale chez les étudiants lors de la réflexion sur les thèmes proposés pour la recherche. Déjà dans l'état du livre, il est clair que les questions environnementales sont discutées avec des activités insuffisantes, des chiffres, des graphiques et des textes contextualisées sur les impacts environnementaux et à améliorer leur prise de conscience des élèves. Ainsi, les livres apportent un soutien afin que l'enseignant puisse travailler de manière interactive vos classes avec les élèves, dans le but de leur apprentissage, les menant à une vision critique des questions environnementales, en tenant compte des suggestions données pour les traiter avec une plus grande profondeur. Mots-clés: manuel scolaire, enseignement de la géographie, Jataí (GO).

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.

Abstract We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor. In a warming climate, individual organisms may be able to shift their thermal optima through phenotypic plasticity. However, such plasticity is unlikely to be sufficient over the coming centuries. Resilience to warming will also depend on how fast the distribution of traits that define a species can adapt through other methods, in particular through redistribution of the abundance of variants within the population and through genetic evolution. In this paper, we use a simple theoretical ‘trait diffusion’ model to explore how the resilience of a given species to climate change depends on the initial trait diversity (biodiversity), the trait diffusion rate (mutation rate), and the lifetime of the organism. We estimate theoretical dangerous rates of continuous global warming that would exceed the ability of a species to adapt through trait diffusion, and therefore lead to a collapse in the overall productivity of the species. As the rate of adaptation through intraspecies competition and genetic evolution decreases with species lifetime, we find critical rates of change that also depend fundamentally on lifetime. Dangerous rates of warming vary from 1°C per lifetime (at low trait diffusion rate) to 8°C per lifetime (at high trait diffusion rate). We conclude that rapid climate change is liable to favour short-lived organisms (e.g. microbes) rather than longer-lived organisms (e.g. trees).
