Trogloraptor – A New family of Spider (photo montage)

SAN FRANCISCO (August 17, 2012) — A team of scientists and cave conservationists discovered a relatively huge, unique spider in caves and forests of the Pacific Northwest. The novel combination of evolutionary features in this spider, Trogloraptor, compelled them to recognize a new family. A study of the new family and its evolutionary and conservation significance was published in the open access journal ZooKeys on August 17.

The forests of the coastal regions from California to British Columbia are renowned for their unique and ancient animals and plants, such as coast redwoods, tailed frogs, mountain beavers—and now, a large, newly discovered spider. Trogloraptor (or “cave robber”) is named for its cave home and spectacular, elongate claws. It is a spider so evolutionarily special that it represents not only a new genus and species, but also a new family (Trogloraptoridae). Even for the species-rich insects and arachnids, to discover a new, previously unknown family is rare.

A team of citizen scientists from the Western Cave Conservancy and arachnologists from the California Academy of Sciences found these spiders living in caves in southwest Oregon. Colleagues from San Diego State University found more in old-growth redwood forests. Charles Griswold, Curator of Arachnology, Joel Ledford, postdoctoral researcher, and Tracy Audisio, graduate student, all at the California Academy of Sciences, collected, analyzed, and described the new family. Audisio’s participation was supported by the Harriet Exline Frizzell Memorial Fund and by the Summer Systematics Institute at the Academy, which is funded by the National Science Foundation.

Velociraptor spider discovered in Oregon cave (pictures)

Scouring the caves of Southwest Oregon, scientists have made the incredible discovery of a fearsome apex predator with massive, sickle claws. No, it’s not the Velociraptor from Jurassic Park: it’s a large spider that is so unique scientists were forced to create a new taxonomic family for it.

“This is something completely new,” lead author of a paper on the species, Charles Griswold with the California Academy of Sciences, told SFGate. “It’s a historic event.”

The discoverers, who published their description paper in the open-access journal Zoo Keys have named the new species Trogloraptor, which translates loosely to “cave robber,” and they have dubbed a new spider family—Trogloraptoridae—to accommodate what they believe is a primitive spider. The full species name is Trogloraptor marchingtoni after one of its discoverers.

Which Dutch animals die by traffic?


This video from the USA says about itself:

The Oregon Department of Transportation works with partner agencies to protect motorists and wildlife from collisions at wildlife crossing hotspots.

Dutch natural history site waarneming.nl has a list of the ten animal species most often reported as mortal victims of traffic.

Some remarks on this roadkill “Top Ten”: probably, small animals are reported less than bigger species victims, and common species are under-reported, contrary to “spectacular” rare species.

The list (translated from Dutch):

1 Hedgehog – Erinaceus europaeus 6073
2 Polecat – Mustela putorius 1303
3 Hare – Lepus europaeus 1057
4 Barn owl – Tyto alba 633
5 Common toadBufo bufo 614
6 Red fox – Vulpes vulpes 559
7 Beech marten – Martes foina 508
8 Rabbit – Oryctolagus cuniculus 499
9 Brown rat – Rattus norvegicus 435
10 Red squirrel – Sciurus vulgaris 354

PORT ORFORD, Ore. — Michelle Duarte is adept at luring visitors to her WildSpring Guest Habitat, even during the slowest months.

Now she has a new enticement to bring people to the South Coast: The 5-acre resort is one of only three commercial sites on the brand-new Oregon Coast Birding Trail.

Duarte was surprised to learn last year from one of the trail’s creators that WildSpring’s five wooded cabins share land with Pacific-scope flycatchers, tree swallows, chestnut-backed chickadees, golden-crowned kinglets, Swainson’s thrush [see also here], wrentits and a half-dozen other feathered varieties.

Birder Steven Shunk recognized all their calls in just a few minutes.

By outfitting two British Columbia subspecies of Swainson’s thrushes with penny-sized, state-of-the-art geolocators, University of British Columbia researchers have been able to map their wildly divergent migration routes and pinpoint conservation hotspots: here.
