Wetlands are among the most threatened ecosystems in the world. A new study, published in , has found that the loss of wetland areas around the globe since 1700 has likely been overestimated. This is good news overall, however, the global picture hides significant variations, with several regions and distinct wetland types under significant levels of pressure. For instance, temperate river floodplains have been highly impacted while remote boreal-arctic peatlands remain comparatively unharmed.

Snakes and mice don鈥檛 look alike. But much of what we know about skin colouration and patterning in vertebrates generally, including in snakes, is based on lab mice. However, there are limits to what mice can tell us about other vertebrates because they don鈥檛 share all of the same types of colour-producing cells, known as chromatophores. For example, snakes have a type of chromatophore called iridophores that can generate iridescent colours by reflecting light.

Lung cancer is the leading cause of cancer-related deaths in Quebec and Canada, killing more individuals than prostate, colon and breast cancers combined. Thanks to tissue samples from almost 500 lung cancer patients, a group of researchers from 成人VR视频 and Universit茅 Laval were able to identify those who were likely to have a cancer recurrence and require further treatment post-surgery.

For professional athletes, the pressures of competition and stigma surrounding mental health issues can be debilitating to the point where some are leaving the arena for good. Young hockey players are no exception. Fear of negative career repercussions can mean athletes avoid disclosing their mental health concerns.

If you could redesign high school, what might you change? Like most educational institutions across Canada, Montreal鈥檚 English high schools retain structures from the time of the industrial revolution. As the realities of students鈥� lives have transformed, schools are slowly adapting to a knowledge-based economy and unpredictable ecological and social challenges.

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers from 成人VR视频 discovered that while changing temperatures and rainfall had little impact on the crocodiles鈥� gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

To better understand food-related decisions during the pandemic, a team of 成人VR视频 researchers, including School of Human Nutrition Professor Daiva Nielsen and postdoctoral fellow Katherine Labont茅, conducted an online survey among a sample of adults from Quebec to compare grocery shopping behaviours in 2019 and 2020. The study showed that at the beginning of the pandemic, people reduced the frequency of in-store shopping expeditions. This reduction occurred in tandem with a rise in curbside pick-up and delivery.
