Voyage to/from Ancient New Zealand

Voyage to/from Ancient New Zealand

Posted Tue, 30 Sep 2014 09:15:00 GMT by JW Dowey

The marvels of the Pacific Islands were not discovered by Europeans. The Polynesians made brave and fantastic voyages across giant stretches of water to colonise much of Oceania. They may have been helped by favourable winds before 1300AD but the means of their success were giant canoes, carrying livestock, food and colonists. Here is the germ of their story.

Some of the great thinkers have come up with ideas to propagate after-dinner discussion of chat and scribble for eons to come. The whole process took a very short time to evolve, according to this “think-tank for talk.”

Humans don’t have sexual coloured skin, but many primates use their colour to attract mates. The red colour of rhesus monkeys attracts the opposite sex, so perhaps there is hope for redheads yet!

Flight in our birds and bats is an interesting process as well as a part of life that we always seem to want to emulate. Avoiding obstacles within a flock, or negotiating forests is an area we need to study for our own needs, even if we simply use it for in-flight entertainment. The serious use of bird mechanisms for various aircraft such as drones is always likely as robotic systems develop.

How did the peach become selected from the typical forest tree. Was it developed like many fruits as a recent addition to food habits, or did it become domesticated early, like the goat, the dog and the pig, to provide a rich varied diet for early agriculturalists?

Tool use and manufacture, but by birds

The mammals and the birds are in competition. How many species will we find that can understand tool-using concepts, and then socially interact with their uses?

The sale of the most remarkable egg ever known is about to take place. Your local museum may not be able to attract the visitors it would like for a simple egg, but the imagination runs wild at the ancient world this egg would have hatched into!

A lovely species like the Eurasian jackdaw could be expected to have an interesting, eventful and full life among its colleagues, his mate and his nestlings. Not so, I’m afraid, for the high-fliers in society.

Diet in mammals is complex

Diet in mammals is complex

How could you classify the diets of mammals for so long without noting the need many species have for fruit, certain plants, or even a bit of animal material for a so-called herbivore? Carnivores need roughage in the same way the human diet has special requirements and herbivores can cheat by gaining essential minerals they would be unable to extract from plants.

We need these forests to retain some of the remaining carbon. We need these trees so that biodiversity around them remains. We need these animals to represent something of the old earth, that used to work as an entity. We need to act very very quickly.

How are butterflies and moths related?

How are butterflies and moths related?

When science illuminates an area, it's not always easy to see how. In this case we try and show that the brilliant butterfly or moth has a fascinating ancestry and intriguing sets of current relatives. The publication of this paper is great progress, but we doubt if we can fully explain, more than just show the pics and links!

Why and how do island species suffer so much from cats, rats and dogs, and the rest of the invasive species? A few hundred years too late, we might finally be getting around to countering the effects of predators on the most vulnerable of animal species. There are also the native predators to consider, of course.

Nature has wonderful problems to solve, but human help is needed when the precarious genetic integrity of our Pyrenean bears is threatened. One bear has built up the population, but now the inbreeding that threatens all small rare species' populations must be reversed.

When fisheries policies change, we have rarely managed to avoid mistakes in estimating the effects. Here we have happy gannets but when fishing discards are prevented, the rocky islands around Ireland and the rest of Europe will be less populous than before.

This desert ant is an amazing route finder in extreme conditions. Efforts to discover its 'technique' have so far faltered, but this research shows the ant-centric approach works.

Known for migration, their sweet songs and the tremendous breaching behaviour they exhibit near some coasts, the humpbacks are unique, like many whale species. Now it looks like their uniqueness could be threefold.
