Dr Zachary Darnell and Assistant Professor Pablo Munguia tested a bunch of Gulf coast fiddler crabs (Uca Panacea) – both those who still had their major claws and those who had lost theirs.
In the experiment, researchers shone lamps on crabs with an intact major claw and on crabs that were missing theirs.
They measured the crabs' body temperature every 10 minutes and found that the crabs lacking the large claw took much longer to cool down.
Their study focussing on the Gulf coast fiddler crab (Uca Panacea) was recently published in the American Naturalist journal.Read more
The team of researchers focused on the short-term ecological effects of a wind farm in the North Sea. To do so, they analysed the effects of the offshore wind farm near Egmond aan Zee (OWEZ) on benthic organisms, fish, birds and marine mammals.Read more
In the South West marine region for example, gill nets up to eight kilometres wide are having a devastating impact on shark and ray species.Read more
A joint research effort between the University of Hawaii at Mānoa's Hawai'i Institute of Marine Biology(HIMB), University of Tokyo, the Japanese National Institute of Polar Research and the University of Florida has shed new light on the hunting bRead more
Australian Institute of Marine Science (AIMS) scientist Dr Katharina Fabricius has led two research expeditions, with researchers from six countries including Papua New Guinea (PNG), to study three natural CO2 seeps in Milne Bay Province, PNG. This unique location is the only presently known cool, CO2 seep site in tropical waters containing coral reef ecosystems. The study has given scientists unprecedented insights into what coral reefs would look like if greenhouse gas emissions and resulting ocean acidification continues to increase at present rates.Read more
“The findings add fuel to an already fierce debate in the research community on how the echolocation sound is produced”, says Josefin Starkhammar.,
The beam projections have different frequencies and can be sent in different directions. The advantage is probably that the dolphin can locate the object more precisely.

Dead zones form where microscopic plants, known as phytoplankton, are fertilized by excess nutrients, such as fertilizers and sewage, that are generated by human activities and dumped into the ocean by rivers, or more rarely, where they are fertilRead more
For some years, researchers have pinned their hopes on the ability of weed-eating fish to keep the weeds at bay while the corals recover following a major setback like bleaching, a dump of sediment from the land, or a violent cyclone.Read more
This behavior seems to imply a map sense from which the creatures read either absolute or relative location from at least two coordinates.
Direction is one thing but how about position?,
The results demonstrate for the first time that longitude can be encoded into the magnetic positioning system of a migratory animal.
