Dynamics of Invasive Fish Species Revealed

Dynamics of Invasive Fish Species Revealed

Posted Wed, 03 Dec 2014 08:53:00 GMT by Dave Armstrong

When a plant or animal invades your garden, your farm or your lake, the means of dealing with it can be limited. Now we have some understanding of the invasiveness, we can probably do much more to limit these IAS.

How do we know how the oceans and winds will deliver when global warming destroys or present climate systems? The answer will depend on how this new information on Arctic sea-ice fits with various modelling experiments. We need to have information on these unexpected floods, violent hurricanes and killer droughts if we are to have any chance of preventing their worst excesses.

Long suspected of murder, the grey seal is exposed as a regular killer of the smallest whale, the porpoise. They have recently started seeking the blubber from the porpoise, possibly after large numbers of drowned porpoise were made available after their dumping from fishermen’s bycatch.

We worry and then worry again about our turtles, so any good news is welcome, even if one area of success is unlikely to help all the other species. The Olive Ridley turtle was found once in this study reminding us of all the life trials that these unlucky reptiles have to endure.

From Thailand to the southeast of China and then throughout the Sunda shelf much of which is now underwater, the rainforest was supreme. It was delineated by the presence of many species of dipterocarp, entwined with rattans and delicious fruiting trees, all set off with the huge biodiversity of tigers and elephant, Orang-utan and civets. It still remains, but it desperately cries out for conservation – all of that which is left!

The attraction of cats is a puzzle for some and taken for granted by others. In fact, like dogs, they are highly genetically-adapted to be irresistible, otherwise humans would have discarded them both eons ago. Have fun with this great research to ease our guilt at having non-primate commensals. (No, get off the table, you mut!)

The potential for fires to destroy rural and even urban environments has increased. Could the early loss of podocarp forest from Maori fires help to tell us how to combat the vast problems we have nowadays in preventing loss of homes, and harvests, lives and livelihoods?

The ostrich and the quail were used here to check out how a bipedal animal (like ourselves) can be run in an optimised way over rough ground. Of course, the birds and the average human may not be interested in their own evolution of gaits, but engineers have strange deluded ideas of fantastical robots that can operate in theatres we can only dream of.

The modern Eurasian ancestors roamed across Siberia according to a new study, but another paper revealed DNA-enhancing technology using part of prehistoric skulls. We now know roughly when our genes adapted to farming, less sunlight and many other technological advances we made in the past.

The drive to produce offspring has always been as dominant as the enjoyment of food. Australian scientists have now used Scottish fossils to deduce that Estonian fish evolved a jolly dance that has resulted in much more “fun” in their ancestors!

The wonder of bird migration takes a long while to sink in. Perhaps it’s the payload, but tiny birds still seem able to amaze us with their ability to fly thousands of kilometres (or even miles.) This is a unique Australian endemic bird that seems able to detect water a great distances, possibly by smell of desert, air, their brine shrimp food or other olfaction.

To find evidence of how speciation can happen when there is an obvious bio-geographical boundary should be simple. This represents a first, however, for a group colonising New Guinea and evolving a greater size in several instances. The ancestry of these New Guinea geckos, large and small, has been well-traced.

Despite the disappointment of not absorbing any carbon dioxide, this fantastic discovery of an organic crystal in Odense could transform lives of both divers and hospital patients, not forgetting the many other applications we’re sure will arise when this neat oxygen producer is in production.

How do males pay for their dedication to antlers, plumage or dance? In this case the effort to escape a predator is not affected by the peacock’s extravagant tail, or train. Pity the experiment involved removing it- they must have been lost without it.
