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 ]
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 ]
Human disturbances affect the topology of food webs
https://youtu.be/N4D--Wj3JvM What do galaxies and molecular structures have in common? Or trade between countries, communications on the Internet, and trophic relationships within ecosystems? One answer is that they all involve nodes interconnected by flows of mass and energy. In other words, they are networks. The study of networks has revealed intriguing regularities. For example, it is . . . [ Read More ]
Improvements in reports of species redistribution under climate change required
https://youtu.be/DIrNac2Eauk We - Shirin Taherim Babak Naimi, Carsten Rahbek and Miguel B. Araújo - just published the study in Science Advances. We reviewed 240 reports of climate-related species-range shifts and classified them based on three criteria. We ask whether observed distributional shifts are compared against random expectations, whether multicausal factors are examined on . . . [ Read More ]
