Where is the rainforest above located? For the answer see below....
It's in Iran, the Caspian Hyrcanian mixed forests of Gilan province. Here's a precipitation map of Iran:

clock | July 27, 2009Miriam Goldstein of the Oyster's Garter and Double X blogs (follow her on Twitter) is embarking on a sea-faring expedition!
SEAPLEX is a Scripps Institution of Oceanography at UC San Diego project studying plastics - yes, including the rubber duckies - accumulating in the oceans, specifically in the North Pacific Gyre. Miriam is leading the team of PhD students and volunteers who will be studying various aspects of the plastics in the sea and their environmental impact.
Though the life at sea is hard and busy and they will not have much time (or access) to do so, they will try to keep us all…
edyong | July 27, 2009Cities are noisy places. If you ever get annoyed by the constant din of traffic, machinery and increasingly belligerent inhabitants, think about what songbirds must think. Many birds rely on songs to demarcate their territories and make their advances known to mates. They listen out not just for the sounds of seduction or rivalry, but for approaching predators and alarm calls that signify danger. Hearing these vital notes may be the different between life and death.
Last year, I wrote a feature for New Scientist about the effect that urban noise has on songbirds. Those that can't make…

edyong | July 24, 2009In Lake Alexandrina, New Zealand, a population of snails is under threat from a parasitic flatworm, a fluke aptly known as Microphallus. The fluke chemically castrates its snail host and uses its body as a living incubator for its larvae. But the snails have a weapon against these body-snatching foes - sex.
The New Zealand mud snail Potamopyrgus antipodarum is found throughout island's freshwater habitats. They breed either sexually or asexually through cloning, and the two strategies vary in prevalence throughout the lake. In the shallower waters round its margins, sex is the name of the…
clock | July 19, 2009A few months ago, I posted about a very innovative way of using Twitter in science - monitoring fish catch by commercial fishermen.
The first phase of the study is now complete and the results are published in the journal Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science 2009; 1: 143-154: Description and Initial Evaluation of a Text Message Based Reporting Method for Marine Recreational Anglers (PDF) by M. Scott Baker Jr. and Ian Oeschger. It is relatively short and easy to read, so I recommend you take a look.
The next phase will continue with the program, with…

edyong | July 18, 2009We think of spiders as fearsome hunters, spinners of webs and treacherous mates, but construction workers? Yes, that too. Some groups of spiders - trapdoor and wolf spiders - dig tunnels that they use to ambush passing insects. But these tunnels can also provide shelter and accommodation for other animals, including one of the rarest of Australia's lizards - the pygmy blue-tongue lizard. It seems that the lizard's survival depends entirely on the spiders.
The pygmy blue-tongue is a native of South Australia. It's so rare that zoologists thought it extinct for over 30 years and it re-emerged…

The Japanese bees swarm and bake the giant hornets. But Ed Young reports that there is more to this story.

edyong | July 4, 2009Walks through a forest are often made all the more enjoyable by the chance to watch brightly coloured birds flit between the trees. But birds are not just mere inhabitants of forests - in some parts of the world, they are the key to the trees' survival.
The Serengeti is one such place. Since 1950, around 70-80% of riverside forests have disappeared from this area. Fires seem to be a particular problem, opening large gaps in the canopy that forests can't seem to recover from. To understand why Gregory Sharam from the University of British Columbia has been monitoring the density of the…

In this video, Jane Poynter tells her story of living two years and 20 minutes in Biosphere 2 -- an experience that provoked her to explore how we might sustain life in the harshest of environments. This is the first TED talk drawn from an independently organized TEDx event, held at the University of Southern California. [15:54]

awild | June 23, 2009An ant, climbing from the pit of a predatory ant lion.
The predator, buried in sand at the base of the pit, hurls a volley of debris towards its target.
Caught in the falling sand, the ant slides back into the pit.
The ant tries to escape, and again the unseen predator hurls a load of sand into her path.
No matter which way the ant turns, the ant lion adjusts its aim, sending up clouds of sand and preventing the ant from gaining traction on the steep walls of the pit.
In the end, the ant lion wins.
A tight crop of the previous image shows the jaws of the ant lion reaching up around the…
awild | June 21, 2009dawn in the scrub
I spent last week in central Florida at the Archbold Biological Station.
Archbold preserves 5,000 hectares of Florida sand scrub, some of the last remaining patches of an ecosystem now largely lost to agriculture and strip malls. The sand scrub is an odd place, a fossil beach from when sea levels were high enough to restrict peninsular Florida to a narrow sandbar. Water runs right through the coarse sand, leaving the scrub looking much like a desert in spite of regular afternoon rains. Cacti thrive. It is a paradoxical place.
The scrub is also remarkable for…

In 1979, somewhere in Dartmoor, a butterfly died. That would hardly have been an exceptional event, but this individual was a Large Blue butterfly (Maculinea arion) and it was the last of its kind in the United Kingdom. Over more than a century, the Large Blue's population had been declining and it was finally declared nationally extinct 30 years ago.
Now, it's back. A bold conservation effort managed to work out the factors behind the butterfly's decline, and resurrect this vanished species. The Large Blue's reintroduction has been one of conservation's flagship successes and it was the…
