Otters don’t tend to be very visible to us, but they are more abundant than we might perceive them to be. Otters mostly live in isolation of one another, yet they manage to remotely communicate to one another without the aid of modern technology that we so often depend upon for communication.
On this blog, I previously wrote how otters communicate with one another using their spraints (faeces). They use them to mark their territory and to leave messages for other otters. As part of the rese........ Read more »

Increased sea temperature due to climate change can influence the distribution, abundance and seasonal timing of zooplankton. Changing zooplankton dynamics might in turn impact the higher trophic levels, such as fish and seabirds, feeding on these animals. In a recent paper, we show that temperature variation in the Atlantic waters of the Norwegian Sea and Barents Sea might have stronger effects on the abundance of the younger than older development stages of Calanus fin........

Rory Wilson recalls some nervous waterbirds.
"I've seen pelicans in Galapagos, in the port," the Swansea University biologist says. One set of birds was standing by the fish-gutting area and waiting for scraps, while another group stood out of the fray in some nearby bushes. Although both sets of pelicans acted the same, a closer look at the birds waiting for fish scraps revealed that they were quaking slightly. The tips of their wings trembled.
Wilson thinks the tremor in the pelicans... Read more »

Plant science is probably one of the least appreciated fields of life sciences, and yet, perhaps no other research area has produced as many technological advances beneficial for society. In an open letterreleased last month, 21 out of the 27 most cited plant scientists in Europe pledged decision makers to back plant research, which they feel is currently threatened by lack of funding and global public and political opposition to genetically modified organisms (GMOs). “In comparison for i........

There is a misfortunate bat species that is going through a bit of an identity crisis at the moment. This poor creature is Natterer’s bat, or Myotis nattereri to give it its formal name (named after the distinguished 19th Century Austrian naturalist Johann Natterer, not because it makes a lot of noise, as I have sometimes been asked). Natterer’s bat is distributed across Europe and north-west Africa, and is mainly considered to be a woodland species- in other words, it has specialised in hun........ Read more »
The Eurasian red squirrel is, in my opinion at least, one of the cutest additions to the Irish countryside. The little ear tufts of the red squirrel help differentiate it from the invasive grey squirrel, the North American competitor of the red squirrel introduced here about 100 years ago. Other features include the size difference, as the grey squirrel is quite a bit larger. You might think that it should be relatively easy to differentiate the species by colour, but colourations can vary consi........ Read more »

In the summer of 2010, over 20 million people were affected by the summer floods in Pakistan. Millions lost access to shelter and clean water, and became dependent on aid in the form of food, drinking water, tents, clothes and medical supplies in order to survive this humanitarian disaster. It is estimated that at least $1.5 billion to $2 billion were provided as aid by governments, NGOs, charity organizations and private individuals from all around the world, and helped contain the devastating ........

Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture....

How much does global warming really cost the world? Determining the Social Cost of Carbon helps put a actual dollar value on the climate damages per ton of CO2 released, and is used by -- among others -- policymakers to help determine the costs and benefits of climate policies. Remember, even on a global scale, the bottom line will always be profit. But now a group of economists and lawyers urge several improvements to the government's Social Cost of Carbon figure that would impose a regular, tr........ Read more »

Climate change is thought to change many aspects of the marine life. Among others, one can mention changes in species distribution (immigration of species; new species coming to northern areas), the rate of development (warmer the temperature, the faster is the development), and change in the timing of the reproduction. The latter has recently caught a lot of attention around a nearly 50 years old hypothesis of the British fisheries biologist David Cushing.

Climate change, and especially alteration in sea temperature, is expected to have major effects on the distribution and abundance of marine fish. This is in particular the case in northern high-latitude marine ecosystems, where IPCC expects global warming to be especially pronounced.

...It was during this trip that we paid a visit to the cork oak-dominated Montado region. It is an open savannah-like landscape managed for centuries as an agri-silvo-pastoral system, dominated by evergreen oak and a rotational grazing system for domestic animals. The main commercial products from the region include cork (at one time, the only way to cork wine bottles) from cork oak trees, wood for charcoal and meat. Crops such as corn were at one time also cultivated in the region, but this tre........ Read more »

Global warming, it’s a bigger deal than some people seem to realize. For years science has pointed to the increased carbon dioxide output as the main reason for man-made global warming. However, there has been no evidence to directly link CO2 output to global warming, well until now. Research has identified, for the first time, how global warming is related to the amount of carbon emitted.... Read more »

While everyone (but seemingly the media) is on basically the same page with the fact that global warming is a human caused problem — and one we need to fix the effects of this change are still coming to light.
