    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.

    Este artigo reporta os resultados de uma revisĂŁo sistemática de literatura sobre as definições e nĂ­veis de envolvimento de usuários no processo de projeto. Embora muitos estudos tenham ressaltado a importância do envolvimento de usuários para a qualidade tanto do processo quanto do produto final, o termo ainda nĂŁo possui uma definição clara, e diferentes modelos descrevem diversos nĂ­veis de envolvimento, o que dificulta a consolidação do conhecimento nesta área. O presente estudo foca o mapeamento das definições de envolvimento de usuários e comparações das diferentes propostas de nĂ­veis de envolvimento, para delinear uma definição clara do termo, baseada nos nĂ­veis de envolvimento, e contribuir para a consolidação da teoria de envolvimento do usuário na área de projeto de arquitetura. AlĂ©m disto, a presente pesquisa auxilia arquitetos a encontrar o nĂ­vel de envolvimento de usuário mais apropriado ao projeto que desenvolvem, contribuindo para a melhoria desta prática.This paper reports results of a systematic literature review on the definitions and levels of user involvement in the design process. Although many studies have highlighted the importance of user involvement for the quality of both process and final product, the term still lacks a clear definition and different models describe diverse involvement levels, which are detrimental to the advancement of knowledge in the area. The present study focused on the mapping of definitions of user involvement and comparisons of the different proposals of involvement levels for outlining a clear definition of the term, based on the levels of involvement, and contributing to the consolidation of the theory of user involvement in the field of architectural design.  Moreover, this research assists architects to find the most appropriate level of user involvement for the design they are developing, improving the practice of involving users in the design process
