Common species are most important in ecosystems

Common species are most important in ecosystems

Posted Tue, 27 May 2014 10:13:00 GMT by JW Dowey

The abyss and the intertidal zone share ecological characteristics with all known marine ecosystems. They simply use their abundant animas as providers of shelter and many other functions. Rare species have a lesser role within the community.

Personality in great tits stretches as far as deciding whether to risk your life for your eggs. Would you go back home if somebody seems to threaten your cosy little nest in some unknown way? Insights into survival, evolution of boldness, domesticity and even our own reactions to stress can be found here!

We love the muse of Beethoven, Shakespeare and Keats. But as we tend to lose their habitat, many will never have the chance to hear what has now been verified as the richest song in the bird world. Long live the little brown bird.

How sloths breathe upside down

The 3-fingered or 3-toed sloth can finally breathe a sloth sigh of relief. We've finally found out how it manages to breathe upside down. To be honest, we’d never thought there was a problem, but there is.

This little sea-bream is able to conveniently dispose of and control jellyfish populations, just as the big turtles can. The research involved has a lot of relevance to turtle conservation as well as the massive jellyfish blooms reported in Japan and other parts of the world.

Leatherback logging in the Atlantic

The study of marine turtles is linked with tagging of many other animals, but if we lose these leatherback giants of the seas, we will have lost a species that can relay how conditions millions of years ago influenced even bigger turtles and of course every other species that existed at the time.

Swimming sloths with aquatic adaptations

Swimming sloths with aquatic adaptations

Posted Wed, 12 Mar 2014 07:17:00 GMT by JW Dowey

One group of sloths made the quite unlikely shift to water, possibly because of a drying environment in the Miocene. This clever paper shows how they coped with a marine life, just like early whales, by adapting their bone compactness. Our pygmy sloths on the Panamanian island of Isla Escudo de Veraguas are the most recent speciation, around 9,000 years ago. These guys were several species on a sea trip!

Animals of unfamiliar as well as familiar types took up niches in the ancient ecosystems, as birds and mammals developed and, of course, feathered dinosaurs ruled the roost!

We can't find the fossils and the genome can give only some hints. How did the first human-like species survive and why did they have to be black. Mel Greaves has the answers.

When you want to count how many rare animals are out there, remote cameras have come into their own. Now even the spy in the sky can help, with the first study of a whale species that has been having high mortality problems with its calves.

We need technology to discover where and how endangered species survive. The US government have just declared 15 more Hawaiian species as endangered, but the islands have so many, it is difficult to see how they can all be conserved.

Flores Human Dwarf Debate

Posted Sun, 02 Feb 2014 17:01:01 GMT by Dave Armstrong

The feet of the Flores hominid might be more conclusive than the small head, if we ever come to better conclusions about its ecology, niche or even what it ate. The point is, we can’t even decide on its species and it's only 18,000 years old.

When they rage at the dingo, the ignorant fail to appreciate what many of us have thought. The need for such predation and scavenging is always present, plus we all need more natural systems than the awesome monoculture we get from tropical oil palms to “recyclable” spruce plantations.

You would expect an evolutionary shift to be a trend, but in one great family of fish, there is little evidence that lightning strikes twice, especially in the same freshwater ecosystem!
