Life Sciences

Deliane Vieira Penha de Oliveira, a dedicated scientist, has focused her research on the vulnerability of trees in the Tapajós tropical forest, particularly on the characteristics that contribute to plant mortality. Her academic journey began with an undergraduate degree in biological sciences from the Federal University of Pará, followed by a master’s in natural resources of the Amazon and a PhD in society, nature, and development, both from the Federal University of Western Pará. She has further honed her expertise through four postdoctoral periods, two at UFOPA, one at the National Institute of Amazonian Research, and a postdoctoral fellowship at the University of Arizona, USA.

Demonstrating a remarkable ability to balance personal life with her passion for research, Oliveira became pregnant at the end of these academic phases and now has four children, including a four-legged one. Despite her scientific passion and the sweetness of motherhood, the scientist faced burnout in 2022, which motivated her to seek a lighter role in her academic journey. In addition to her connection with science, she coordinates the page “Niaras do Tapajós,” where she not only shares academic experiences in the Amazon but also creates a safe space for discussions about challenges in academia, particularly those related to mental health, offering support and guidance to students at the Federal University of Western Pará.


Which characteristics of tropical trees best indicate vulnerability to global changes?
Science / Life Sciences

Why do trees die? This is the million-dollar question, especially after several studies have indicated increased tree mortality due to rising temperatures and increasingly severe droughts worldwide. Tropical forests provide ecosystem services crucial for climate balance and the conservation of global biodiversity, making it essential to understand the factors related to tree mortality in these environments. This project aims to determine which characteristics of tropical species best indicate vulnerability to global changes. We will investigate chemical defense traits against pathogens and structural factors related to water use in the most abundant trees of the Tapajós tropical forest in the Amazon, to assess whether integrating these traits can help improve predictions of which trees are more vulnerable to mortality in tropical ecosystems due to water stress and pathogen activity.
