This is a video about hoverflies.
From Natuurmonumenten in the Netherlands:
Natuurmonumenten works for hoverflies, a group of insects with 328 species in the Netherlands. In the Nieuwkoopse Plassen (Zuid-Holland province), for example. …
Recently, species #328 was discovered, the “verborgen sapzwever”. The book ‘De Nederlandse zweefvliegen’ [The Dutch hoverflies] will be published in the summer of 2008 by Naturalis and Stichting EIS-Nederland.
Ruddy-headed Goose: less than 1,000 remain in mainland South America
The first ever Convention on Migratory Species (CMS) agreement for an American migratory bird species has been announced. The new agreement calls for both Argentina and Chile to coordinate conservation measures that will halt recent declines in the mainland South American population of Ruddy-headed Goose Chloephaga rubidiceps.

Seven new butterflies recorded at National Trust site in ten years
August 2007. The limestone hills around the National Trust’s Arnside Knott and Silverdale properties on the Lancashire/Cumbria border have been witnessing a remarkable butterfly ‘invasion’.
In less than a decade, no less than seven species of butterfly new to the area have begun colonising the sites, as climate change and changing habitat affect their traditional distribution.
One of the best known areas for butterflies in the country, more than half of all the species of butterfly in the UK can now be found in this area. There are now 34 species of butterfly found at Arnside Knott and Silverdale.
The seven butterflies that have arrived in Arnside and Silverdale in the last decade include:
* The Speckled Wood, which is now widespread and locally common throughout, both sides of the estuary;
* The Gatekeeper, has just arrived and present in small colonies all over Arnside Knott and Silverdale;
* The Ringlet arrived at Gait Barrows and other places around Silverdale this summer in numbers;
* The Comma is now diffuse throughout the region.
* The Silver-washed Fritillary exploded in the Witherslack woods, north of the estuary, in the early 1990s and is now appearing south of the river;
* The White-letter Hairstreak was first seen at Silverdale in 1983, then vanished, and is now back again properly at a number of sites;
* The Small Skipper is colonising lots of grassy places around Arnside Knott and Silverdale.

From Wildlife Extra:
Frogs in the Masoala’s wet forests [in Madagascar] exploit a variety of microhabitats ranging from the ground to the upper canopy. These microhabitats also include plant-held waters, referred to collectively as phytotelmata. While surveying the herpetofauna at various canopy levels and studying phytotelm community structure, we found a species of frog that could not be classified as a currently recognized species.
The new species, Anodonthyla hutchisoni, is named in honour of a lifetime of dedication to excellence in herpetology by V. H. Hutchison.
Two more frogs
The team also discovered two new, very small, frogs, Platypelis tetra which measures just 20mm) and the much larger (30 mm) Platypelis mavomavo. Both these frogs were collected within a day of each other on another expedition in 2002 by Dr. F. Andreone.
The team also made an interesting discovery of two species of tree-climbing crabs belonging to two families (Potamonautidae and Sesarmidae) that were collected from container microhabitats (phytotelmata) in rainforest in the Masoala Peninsula. This isolated peninsula supports one of the last undisturbed intact primary humid tropical forests in Madagascar, and is free from much of the human encroachment that has caused the environmental problems seen elsewhere on that island.

August 30, 2007—Triggered by body heat, a remote camera recently captured this image of the elusive Chinese mountain cat at about 12,300 feet (3,750 meters) on the edge of the Tibetan Plateau in China’s Sichuan Province.
A total of eight images of the feline represent the first time the mountain cat has been photographed in the wild, said Jim Sanderson, a cat specialist with the Wildlife Conservation Network who led the team that snapped the rare shots. A paper about the cat will appear in an upcoming issue of the journal Science.
Sanderson is hoping that the new images will reveal some of the secretive habits that have kept the creature a mystery to scientists for nearly a century.
“Pandas go for a million [U.S.] dollars a year to rent and are very well protected by Chinese law, but there is virtually no protection for this cat,” he told National Geographic News.
“There’s no interest in its conservation because it’s poorly known, but now perhaps this will change.”

Ancient crocodile was longer than tourist bus
August 31 2007 at 02:17AM
Pierrelatte, France – As long as a tourist bus and with jaws big enough to pick up a cow, “Sarcosuchus imperator” lived 110 million years ago and was surely the biggest, meanest crocodile to ever roam the Earth.
This week its scales-and-blood likeness was unveiled by the man who first identified and named the amphibious predator based on fossil remains found in Niger more than 40 years ago.
“It is impressive to finally see this animal in the flesh – excuse me, I mean in resin,” said a smiling Philippe Taquet, a paleontologist at the Museum of Natural History in Paris.
Measuring 12m from snout to tail, and weighing in at 10 tons, Sarco – as the beast is known among dinosaur buffs – undoubtedly chomped on big fish and small dinosaurs, dragging them into the tropical rivers that once criss-crossed what is today the Sahara.
The reconstruction of the animal by the French company Ophys required 1 800 hours of work and 750kg of resin, and was undertaken under the watchful eye of paleontologist France de Lapparent de Broin, who co-authored with Taquet the first scientific article on Sarco in 1966.
Sarco’s new home will be the Crocodile Farm, an wildlife park with 400 of the pre-historic reptile’s modern cousins, along with an assortment of giant turtles. – Sapa-AFP
Nigersaurus taqueti was a contemporary of Sarcosuchus.
