Polychaetes are segmented worms that live in nearly all marine habitats, from the shallow seashore or estuaries to the deep sea. They are very abundant, often making up as much as 70% of the animals found in an area. Not only are there many of them, but they are very important in contributing to ...
Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms that determine how big an organism can grow?
There are already plenty of mosquitoes in Australia. They bring pest and public health risks to many parts of the country. Now a new species of mosquito, Aedes shehzadae, has been discovered 90 years after the first (and only other observation) of it in Papua New Guinea—and it's thanks to citize ...
The list of bird species found in Nepal has now grown to 891, after a bird never before seen in the country was spotted at a national park in the south.

The European Union (EU) delegation to Jamaica has underscored its commitment to continue helping the island to implement measures that will lessen the possibly devastating impact of climate change.
Climate negotiators crave a return to “normality” when global warming dominated the agenda — but war, hunger and disease overshadowed the beginning of talks in Bonn, Germany Monday.
For almost a year, climate scientists have sounded one clear message. The world’s totemic goal of holding average global temperature rises to 1.5°C is still technically within our grasp, but will slip without a dramatic course correction by humanity.
Nations must not lose hope and focus in tackling global warming despite the many obstacles to international co-operation, the UN climate chief said on Monday at the start of a 10-day meeting in Bonn, Germany.
Scientists welcome "honest conversation" about the long standing threat of sea level rise driven by climate change, warning coastal protection measures cannot save all communities, even if the Environment Agency could afford them everywhere.
The 6th National Report to the Convention on Biological Diversity is the most comprehensive analysis yet of the country’s biodiversity, with more than 100 experts from different fields contributing to the effort.
Scientists have now confirmed that a certain well-known tree in Southeast Asia is actually two species, not one. Indigenous people in Borneo, however, have known this all along.
