    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050.

    Introdução: A comunicação na contemporaneidade é palco de expressivas transformações mediando relações em todo o corpo social. Campanhas publicitárias se tornam produtos indispensáveis a todos os setores e instâncias sociais em vias de fruição de resultados e otimização de projetos. Também o Terceiro Setor, ao largo de sua fenomenologia, alia-se ao fazer publicitário na condução de suas atividades. Objetivo: Neste prospecto, o presente trabalho propõe-se a desenvolver uma campanha publicitária para a Casa de Apoio Santa Bernadete, entidade filantrópica voltada ao acolhimento do público com diagnóstico de câncer e vulnerabilidade social. Metodologia: Através de um estudo de caso, procedeu-se à entrevista, dirigida ao núcleo diretor da instituição, marcando-se o viço publicitário da campanha. Resultados: O engajamento voluntário foi o intento escolhido pela entidade no desenvolvimento do trabalho. Os dados coletados foram combinados em briefing na orientação das decisões criativas, resultando no produto de uma campanha publicitária pertinente à necessidade comunicacional da casa. Considerações finais: A publicidade emerge como uma ferramenta de grande valia no trato organizacional, aqui se denota o usufruto dos produtos de comunicação na efetivação de resultados de escopo assistencial.</p
