Birds like it sweet, bees like it sweeter
Posted Thu, 13 Oct 2011 09:16:00 GMT by Dale KieferMIT mathematicians delved into the arena of biology recently to explore optimization in nature. It turns out, bees are 'dippers' who feed by probing flowers with their tongues. For them, a thicker, sweeter fluid is best. But birds and butterflies draw nectar through thin tubes, and that's easier when flowers supply a thinner, less sugary fluid.

Release the 'Kraken', well the Artistic Triassic Cephalopod
Posted Mon, 10 Oct 2011 14:07:00 GMT by Dave CollierA strange explanation is given for a puzzling arrangement of Triassic era fossils. It could seem strange to apply the word 'artistic' to a Triassic creature but an in-depth examination of Ichthyosaur fossils has renewed the general confusion about what happened to the animals on display at Nevada's Berlin-Ichthyosaur State Park.

Jumping like a fish out of water
Posted Thu, 06 Oct 2011 17:20:00 GMT by Dave ArmstrongProf. 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
Posted Thu, 06 Oct 2011 09:29:00 GMT by Dave ArmstrongDiscovery 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.

Largest ever butterfly map completed
Posted Wed, 05 Oct 2011 15:37:00 GMT by Colin RickettsA 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
Posted Wed, 05 Oct 2011 13:21:00 GMT by Colin RickettsThe 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.

Chick attacks highlighted in study on the Nazca booby
Posted Wed, 05 Oct 2011 07:26:00 GMT by Dave ArmstrongNazca 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.

Video documents tool use by wild fish
Posted Sun, 02 Oct 2011 18:02:00 GMT by Dale KieferA new video documents, for the first time, tool use by a fish. The video shows an orange-dotted tuskfish - a type of Wrassedigging 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.

Elephants can take the heat
Posted Sun, 02 Oct 2011 16:11:01 GMT by Dale KieferNew 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.

First Usain Bolt, and now, Bats
Posted Sat, 01 Oct 2011 18:25:00 GMT by Dave ArmstrongThe unique audio reception of the bats is aided by this truly freaky muscle that contracts 100X faster than normal muscle and 20X faster than the fastest human muscle, surrounding the eye. Weep ye who admire Mr. Bolts 100 metres: this bat could do it a little better, in 0.1 seconds!

Beetles keeping it bottled-up
Posted Fri, 30 Sep 2011 16:17:05 GMT by Dave ArmstrongThe 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.

A Frog's tale
Posted Fri, 30 Sep 2011 12:06:00 GMT by Dave ArmstrongAustralian 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 call of the koala may have some hidden tricks
Posted Thu, 29 Sep 2011 21:31:00 GMT by Dave CollierThe 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.

A Variety of Fruit Selections
Posted Thu, 29 Sep 2011 12:04:00 GMT by Dave ArmstrongBotanists 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
Posted Thu, 29 Sep 2011 10:38:00 GMT by Dave ArmstrongBirds 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.

Air pollution is rarely linked to water pollution, but the strong links will soon be obvious, just as the surface air movement is influenced by the ocean currents and the temperatures of both. While scientific models can tell us what is going to happen as the earth warms, climate change will also be influenced by small so far neglected fluctuations in chemistry such as these pH changes in our oceans, affecting billions of creatures, and of course, us.
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.
The Sumatran problem where people and industry are always given priority over natural ecosystems is reaching a climax, as the last vestiges of tropical forest go under thee axe. apart from the smoke pollution hanging over the burning, the animal species involved are among the rarest large animals anywhere. It's incredible that local interests can still prevent national government and international organisations from trying to conserve these precious areas still left.
