Lizards can stomach island living
2015-08-31 12:00:00| LifeSciencesWorld
[NEWS] Life on an island isn't always easy. To make the most of the little there is to eat on many Greek islands, the digestive system of Balkan green lizards has evolved considerably compared to family members on the mainland. Surprisingly, many of these insect-eating lizards even have special valves that help to digest plants. These are some of the findings¹ from a study led by Konstantinos Sagonas of the National and Kapodistrian University of Athens in Greece, publishe…

Global warming lethal to baby lizards: Nests become heat traps
2015-08-18 18:02:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: The expected impact of climate change on North American lizards is much worse than first thought. A team of biologists led by Arizona State University investigators has discovered that lizard embryos die when subjected to a temperature of 110 degrees Fahrenheit even for a few minutes. The researchers also discovered a bias in previous studies, which ignored early life stages such as embryos. Embryonic lizards are immobile and cannot seek shade or cool off when their surrounding soil becomes hot....

Climate-change is turning male dragon lizards into females
2015-07-04 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A climate-induced change of male dragons into females occurring in the wild has been confirmed for the first time, according to University of Canberra research recently published on the cover of international journal Nature. The researchers, who have long studied Australia's bearded dragon lizards, have been able to show that a reptile's sex determination process can switch rapidly from one determined by chromosomes to one determined by temperature. Lead author Dr Clare Holleley, a postdoctoral...

Logistics and Lizards Disrupt Chevrons Project Off Australia

New York Times: Getting anything to Chevrons gas-processing plant on Barrow Island is a bit of a trick. Some supplies travel 15 hours from Perth to a supply base for shipping. En route, trucks cannot stop under trees, to avoid picking up bugs and bird droppings. When people and cargo finally make it to the island, an army of 300 enforces a quarantine: Every Velcro strap on clothing and bags is checked for seed pods, boots are scrubbed free of dirt and pants with cuffs never even make it ashore. Such measures...

Climate Change Forces Tropical Lizards Swiftly Adapt
2014-09-17 00:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Climate change is affecting all sorts of animals, from sharks to polar bears to birds, but new research has focused on tropical lizards, which have learned to swiftly adapt in order to survive. Previous research has found that tropical species, because they're already tolerating extreme heat, are most vulnerable to changing ecosystems as a result of climate change. But scientists from Dartmouth University in New Hampshire and the University of Virginia believe some reptiles might be able to evolve...
