Wait, fish make sounds?

Wait, fish make sounds?

Biology

By Invited Researcher

While they may lack some of the melodic qualities of birds or whales, there are almost 1,000 species of fish that use sounds to communicate, and possibly many more. Yet, despite nearly 150 years of contemporary scientific research into fish sound production, there was no global inventory of fish species known to make sounds. Until […]

Future evolution: from looks to brains and personality, how will humans change in the next 10,000 years?

Humanity is the unlikely result of 4 billion years of evolution. From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves – evolution shaped us. Organisms reproduced imperfectly. Mistakes made when copying genes sometimes made them better fit to […]

Cod ‘supergenes’ reveal how they are evolving in response to overfishing

Cod ‘supergenes’ reveal how they are evolving in response to overfishing

BiologyEvolutionGenetics

By Invited Researcher

Cod “supergenes” have shed light on how they respond to overfishing, and these supergenes could make them more resilient to other environmental changes. That’s according to a new study published by scientists in Norway. This could be good news, in that cod have genetic architecture in place that will permit them to respond to climate […]

Seagulls, songbirds and parrots: what new research tells us about their cognitive ability

Seagulls, songbirds and parrots: what new research tells us about their cognitive ability

BiologyEthology

By Invited Researcher

As you can imagine, a human intelligence test doesn’t really cut it for birds. It isn’t that easy to assess how an animal perceives information from the environment, processes it and decides to act. But researchers have developed a range of clever experiments to find out more about their cognitive abilities. Do they recognise each […]

Invasive species are threatening Antarctica’s fragile ecosystems

Invasive species are threatening Antarctica’s fragile ecosystems

BiologyEcology

We tend to think Antarctica is isolated and far away – biologically speaking, this is true. But the continent is busier than you probably imagine, with many national programs and tourist operators crisscrossing the globe to get there. And each vessel, each cargo item, and each person could be harbouring non-native species, hitchhiking their way […]

A forgotten mangrove forest around remote inland lagoons in Mexico’s Yucatan tells a story of rising seas

The San Pedro River winds from rainforests in Guatemala through the Yucatan Peninsula in eastern Mexico. There, this peaceful river widens into a series of slow-flowing lakes. Along a remote 50-mile (80-kilometer) stretch, thousands of red mangroves – trees commonly found along tropical coastlines – line the river’s banks and gentle waterfalls. Unlike mangroves elsewhere […]
