Sea Turtle Success Story!

Jaelynn Hart / Staff Writer It’s not very often that humanity gets to pat itself on the back for having a positive effect on the environment, but scientists are labeling sea turtles as a “global conservation success story” as the population numbers rise away from the brink of extinction.

The complex evolution of the big cats — Why Evolution Is True

A new paper in Science Advances by Henrique V. Figueiró et al. (reference below, free download with legal UnPaywall app) resolves the contested phylogeny (family tree) of five big cat species: lion, leopard, jaguar, snow leopard, and tiger. In so doing, the researchers uncovered some interesting evolutionary history. Previously, the family tree of this group had […]

World’s First Offshore Wind Farm Retires: A Post-Mortem

Wonder what the verdict will be…

Iowa Climate Science Education

The first-ever offshore wind farm, Vindeby, in Danish waters, is being decommissioned after twenty-five years, DONG Energy has announced.[1]By its nature it was an experiment, and we can now see whether or not is has been a successful alternative to fossil or nuclear-fuelled electricity.

It consisted of eleven turbines, each with a capacity of 0.45 MW, giving a total export capacity for the wind farm of 5 MW. The hub height of each turbine was 37.5 m and blade height 17 m, small by today’s standards. Because of its date of construction, it would have been all but totally reliant on conventional energy for its manufacture and installation. The original stated project cost was £7.16 million in 1991, which is equivalent to approximately £10 million today.[2]

During its lifetime, it delivered 243 GWh to the Danish electricity grid. This means that the actual amount of electricity…

Helping American great horned owls nesting

A good project…

Dear Kitty. Some blog

This 2016 video from Canada is called Spectacular Footage of Great Horned Owl | The Nature of Things | CBC.

From the NestWatch eNewsletter in the USA, October 2017:

Hoot Suite

The leaves are falling and the owls are hooting. During autumn, juveniles disperse and males stand guard on their territories resulting in increased vocalization among the who’s who of the owl world. Now is the time to build and install owl nest boxes or in the case of Great Horned Owls, a nest cone. Find out what owls live in your region and habitat, and download a free plan using our Right Bird, Right House tool.

Try your hand at our easiest project, a Great Horned Owl nest cone. Why a cone? Great Horned Owls are extraordinarily adaptive in their nest site selection. They use old nests such as those of a Red-tailed Hawk or an American Crow, cliffs, deserted…
