Sailfish hunt, but is cooperation evolving?

Sailfish hunt, but is cooperation evolving?

Posted Wed, 02 Nov 2016 10:45:00 GMT by Dave Armstrong

The sailfish is a magnificent specimen, but not for any static display. It deserves to be given its niche in the open ocean, at the highest speeds of 70mph (110kph), perfecting their hunting of tuna, mackerel. sardine and squid. The fish grows rapidly, lives only around 4 years and inhabits warm waters and as we see here, hunts with that great, vicious bill, by damaging as many prey as it catches!

Giant Antarctic marine reserve: international compromise or sham?

Giant Antarctic marine reserve: international compromise or sham?

Will the Russians maintain or increase their fisheries near and in the protected Ross Sea? Other nations are also fishing there, and few vessels will report any infringement of the agreed protections in a simply enormous area of uninhabited Antarctica and its surrounding islands. This is just one political aspect of this new cooperation. It’s the conservation that matters, but tell that to the sea-angels!

Just what impact can we expect as large carnivores are returning to old haunts, despite a modern-day increase in the human populations of Europe and North America (maybe even in South America, Africa and Asia?) Would you vote for more ecosystem management like this?

The lack of light reaching the animals in the deep sea is mirrored in a total lack of transparency in the Marine Stewardship Council, today in London. Read on to look at the implications for one large fish species as well as our sensitive bottoms!

A revolution took place in the Pacific over a 30-year period. Between the 1980s and 2014, new groups of sperm whales replaced the thousands who had normally occupied the Galápagos Islands area. Who was who and where did they emigrate or immigrate? The answers are here.

Could humans benefit from a gene that speeds up the sperm as it swims? In a deer mouse, it works wonders for up to 14 litters per year and 9 offspring per litter! You do the math.

We will soon have many unexpected insights into human and other species’ problems such as disease or simply anthropology. The chemicals that control our every movement and thought are inherited. Now even the dogs we breed can be recruited to help understand and back-up documentation of how inter-related we all are. Cancer and other disease problems are certainly being answered with this kind of research. Next we could see even more advances in research using information gleaned from other species.

The mechanisms of shelf-sea fronts are poorly understood. As a front passes, how do plankton and their consumers contribute to the ecology of sea and land nearby? Many species of predator specialise in visiting these fronts, whether transient or fixed, and using the warmer temperatures, the varying productivity and the food supply that gannets find a valuable diet during the breeding season.

Wave power or tidal power? The answer probably depends on where you are. If you have the frightening power that has always inspired names like Cape Wrath, then those tides should produce the most power in Europe. On the other hand, the regular movement of waves could well be capable of inspiring a design to accumulate energy over a lengthy period, albeit with less energy production per unit.

Posted Wed, 14 Sep 2016 18:25:00 GMT by Dave Armstrong

We’re afraid that we have neglected the food security side of our responsibilities. Articles on Politics and Health have been published at the expense of this vital area, as the effects of consolidating food reserves are not only to alleviate criminal use of bushmeat, theft and extortion. We must also preserve areas for wildlife where otherwise people have been forced to cut down their forest to grow more crops/sell timber/build mines, roads or various infrastructure. GODAN are gathering in New York to spread expertise on agriculture and nutrition that will feed the parts of the world that are starving.

The research effort on the sunfish now has its genome: one of the most useful tools to use on a species to discover how it has evolved such remarkable anatomy. It has been called a natural mutant, but it has simply and rapidly adapted to its oceanic habitat and food chain. How this was achieved within the genome is a story that will now unravel with more and more research into this fish, its adaptations and population genetics and that of many others.

Boom time or bust? The terrible effects of the loss of our Arctic sea ice have been well-advertised. Rearing young, or simply hunting prey, in the case of polar bears, has become almost impossible where the ice has gone. This relatively good news is of the baleen whales that are benefitting in the Pacific from extra flow as well as upwelling that creates plankton population surges.

How can foxes, badgers and other Carnivores survive when a giant freeway blocks their route to feeding areas? The demography, the genetics and the extinction risk are all considered here, with a resonance for all species that need some kind of wildlife corridor in order to fulfil their life potential.

We need bats, but in the same way we need their prey the insects. It’s impossible to see all the services they perform in eating pests and even spreading seeds in the case of fruit bats, just as we seem to have ignored the bees working at pollination of orchards!
