Visual representation of a network of co-occurrence and the corresponding network of biotic interactions A new study led by researchers at Miguel B. Araújo Lab has pioneered a method for interpreting the complex network of species interactions within ecosystems. Their findings, published today in Nature Ecology and Evolution, offer a significant breakthrough in ecological research, showcasing a . . . [ Read More ]
Report “Biodiversidade 2030” published on paper
Last year, together with a team of five academics and the support of numerous experts dedicated to the environment, Miguel B. Araújo coordinated the first exhaustive reflection on the state of biodiversity conservation in Portugal titled: Biodiversity 2030: A New Agenda for Conservation under Climate Change. For the first time in a document of this nature, a prospective analysis was included on . . . [ Read More ]
Species climate adaptations on land and sea
Latitudinal extent of realised and potential thermal ranges In a new study published today in Nature Ecology and Evolution, an international consortium of researchers led by Nikki Moore PhD student at McGill University, sheds light on how temperature shapes the living patterns of cold-blooded animals, revealing that marine species are more directly influenced by thermal limitations compared to . . .

Multidimensional extreme weather events and their impacts on biodiversity
https://youtu.be/0IgwyxsNNyo?si=iN-o1lxgQsJgu5pJ The increase in intensity and duration of heat waves in the Caribbean and Central American regions over the last 80 years. The interaction between both dimensions is assessed by calculating the MCI, which represents the yearly average cumulative intensity. Climate change is a multifaceted phenomenon that defies simplistic measurements. While . . . [ Read More ]
New Research Reveals Vacant Niches as Key Predictor of Bird Invasion Risk
Representation of vacant niche ratio for a given guild. Each row represents a trophic structure (TS x, y and z). The filling (grey) represents maximum observed richness per trophic structure (left column) and minimum richness (right column) across grid cells (circles). All grid cells in the middle column show a vacant niche ratio of 0.5 yet they have different species richness (grey filling) due . . . [ Read More ]
Marine heatwaves last longer in deeper water
The world's oceans have reached their highest recorded temperatures in 2023, and it is forecasted that the intensity, duration, and frequency of marine heatwaves - defined as periods of elevated sea temperatures lasting at least five days - will continue to increase throughout the century. Until now, the impacts and projections of these events have focused on the sea surface, however, localized . . . [ Read More ]

200 anniversary of Alfred Russel Wallace
Para assinalar os 200 anos do nascimento do grande cientista, Alfred Russel Wallace, transcreve-se em baixo um trecho do posfácio que Miguel Araújo escreveu para a edição de "A Origem das Espécies", de Charles Darwin, publicada pelo jornal Expresso e que refere a importância do tandem Darwin-Wallace. Wallace, além de ser co-autor da teoria da evolução por seleção natural, foi pai da biogeografia . . . [ Read More ]
Além Risco (Beyond Risk) project
Évora was awarded the title of European Capital of Europe in 2027. As part of a series of documentaries, the Além Risco project that Miguel Araújo leads was featured. This is a capacity building and inspirational project aiming at improving climate change adaptation of local communities through tree plantation in urban setting.
