Jumping like a fish out of water

Jumping like a fish out of water

Prof. Alice Gibb watched the catch jump from the net back into the water. It had jumping skills and knew what it wanted to do. Her study of feeding behaviour was abandoned and 'studies of stranding' became the new research aim. By now, she has achieved unbelievable results relevant to the (possibly frequent) evolution of land vertebrates from the fish, more than 300 million years ago.

Acrocanthosaurus atokensis dino tracks discovered in Arkansas

Discovery of giant tracks from the Cretaceous in Arkansas from 120 million years ago. Acrocanthosaurus atokensis is one of the largest carnivores that ever existed. It is likely that the 60 cm x 30 cm footprint fit its profile, perfectly preserved in the desert-like Cretaceous mud.

A European atlas recording the distribution of all of Europe's 441 butterfly species will be a vital tool to record how climate change is affecting these lovely creatures. The work of 272 field volunteers, say the publishers, has been vital to this grand new publication project.

Tasmanian Devils fight hardest battle yet

Tasmanian Devils fight hardest battle yet

Posted Wed, 05 Oct 2011 13:21:00 GMT by Colin Ricketts

The Tasmanian Devil, an animal with a ferocious reputation is fighting for its life against an infectious cancer that is now beyond culling control according to a new study. While culling of diseased livestock is a relatively common agricultural practice, it remains controversial where wild animals are concerned.

Nazca Boobies, related to other ocean travellers such as the famous wandering albatross, live in the Galapagos. Unfortunately, parents have to leave nestlings frequently to fish long-distance. On the islands, such as this booby colony on Isla Espanola, there is an intense interest by certain adults in unrelated chicks, especially when its parents are necessarily absent for long periods.

A new video documents, for the first time, tool use by a fish. The video shows an orange-dotted tuskfish - a type of Wrasse—digging a clam out of the sand, carrying it in its mouth and swimming some distance to an appropriate location, before repeatedly flinging the bivalve against a reef rock to break its hard shell and expose the tasty flesh within.

New research shows how elephants have adapted to extreme heat in a manner similar to desert mammals such as camels. Elephants have evolved a novel strategy for regulating body temperature, which allows them to endure soaring temperatures during the day without succumbing to heat stress.

The resemblance of a beer bottle to a female has been mooted in the past, but rarely remembered the morning after. An Australian (beetle) has now confirmed that 'stubbies' are better! The male Buprestid (jewel) beetle, Julodimorpha bakewelli, is often noticed lolling around near brown beer bottles (stubbies) in Australia.

Australian researchers have found that green tree frogs Litoria spp. use condensation in the same way as windows on frosty mornings. During the dry season from June to September, Ozzy water is a precious commodity. These enterprising Amphibia expose themselves in such a way as to gather the air's excess moisture when temperatures plummet.

The koala has a unusually deep bellow, but we may now have a better understanding of why this is. The bellowing sound of a koala might suggest an animal the size of a hippo. In humans, the size and depth of our voice box, or larynx, directly corresponds to our ability to produce deeper sounds.

Botanists have used perennial plants for thousands of years in the same way as the Earth's major annual food crops. In the beginning, forest trees were little modified by their human 'allies' as exploited wild plants, but this study by Drs. Allison J. Miller and Briana L. Gross assigns an intermediate period to the woody plants bred and modified extensively for domestication.

Singing Cousins

Birds and humans are related, but most people would regard that relationship as you would a distant cousin you don't talk about any more. Singing is a different kettle of fish, it seems. While common patterns in music include phrases that rise then descend (melodic arches), or just have their final note elongated, constraints on the vocal system are likely to have affected them.

If you've reared tadpoles or caterpillars (haven't we all), you may have noticed they tend to grow more quickly in warmer water. It's double the rate for every 10°C. rise in temperature, if you measure it. Dr Andrew Hirst and his team have now discovered more about this growth and temperature mechanism.

New research shows that invasive species introduced 'upstream' spread more rapidly and colonize more successfully than species that are introduced downrange within a given habitat.

Israeli beetles turning the tables on five spp. of Amphibian. The classic instance of predators stalking their live and not-so-innocent food supply is reversed with the prey waiting to be stalked by the naive predator. They then turn the tables by killing the villain - but just where would the observers' sympathies lie?
