Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.

Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.

New measurements of how boundary between onshore glacier and floating ice shelf glides back-and- forth could help predict melting.

Scientists have created a non-invasive movement tracking method called GlowTrack that uses fluorescent dye markers to train artificial intelligence to capture movement, from a single mouse digit to the human hand. GlowTrack has applications spanning biology, robotics, medicine, and beyond.

The Allpahuayo-Mishana National Reserve in Peru has often been described as the most biodiverse rainforest in the world. For example, in recent decades, scientist have discovered several new bird species from the region. Researchers from the University of Turku in Finland have studied the insect biodiversity in Allpahuayo-Mishana for over 20 years. In their latest study, the scientist described a new wasp genus, Capitojoppa, to science.

The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. Scientists describe the second toxin, which had remained elusive until now. Even in low concentrations, it can destroy cells and is similar to substances currently used in cancer treatment. Two years ago, the same team established that the first toxin from the cyanobacterium is the cause of a mysterious disease among bald eagles in the USA.

For the first time, researchers have extracted ancient DNA from Caribbean parrot fossils and archaeological specimens, showing that species thought to be endemic to particular islands were historically more widespread and diverse.

Research shows that birds with more complex skeletons are more specialized and so are less species rich.

The Gulf Stream transport of water through the Florida Strait has slowed by 4% over the past four decades, with a 99% certainty that this weakening is more than expected from random chance, according to a new study.

Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.

Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.

Primate species with better color vision are not more likely to have red skin or fur coloration, as previously thought.

One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers have observed that these birds can give their chicks a better start in life.

When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time.

Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.

Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.

Multiyear La Niña events have become more common over the last 100 years, according to a new study. Five out of six La Nina events since 1998 have lasted more than one year, including an unprecedented triple-year event.

New research shows that mussels are pretty crafty sea creatures: able to withstand marine heatwaves by adjusting their heart rate and other physiological functions, boding well for their survival in future decades as the world heats up.

In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.
