Timor Bush-warbler rediscovered

Fri, Dec 30, 2011

There had been no confirmed field observations of Timor Bush-warbler Bradypterus timorensis since two specimens were collected on Mount Mutis, West Timor, in 1932. A paper published online in BirdLife’s journal, Bird Conservation International (BCI), reports the rediscovery of the Timor Bush-warbler in Timor-Leste (East Timor) in 2009, prompted by the discovery of a previously unknown population of bush-warbler on the island of Alor, Indonesia, to the north.

Timor Bush-warbler was first recognised as a full species in 2000, when along with Russet Bush-warbler B. mandelli and Java Bush-warbler B. montis it was split from Benguet Bush-warbler B. seebohmi. The authors of the BCI paper assign all these species to the genus Locustella.

On Alor, at least 13 male bush warblers were heard singing from shrub and grass beneath woodland and forest edge at 859–1,250 m. On Timor, at least 40 males were heard from tall grassland at 1,720–2,100 m.

The songs are loud and can be readily heard from at least 100 m. However, the birds on both islands were skulking and hard to observe, even while singing. Brief direct views on Alor noted a large, buff-brown, long-tailed bush-warbler. Birds were observed to walk or scurry, mouse-like, on the ground on thin shrub and grass stems. Although they can fly, they do so rarely and probably mostly under cover.

There were substantial differences in habitat use by bush-warblers on Alor and on Timor, presumably resulting from island-specific differences in habitat availability, elevation and land-use pressure. High grazing pressure and repeated fires ensure that there is little or no suitable habitat over much of Timor’s montane habitat, except on steep slopes. There are few known threats to bush-warbler habitat on Alor, but ongoing assessments are needed.

Timor Bush-warbler is considered Near Threatened by BirdLife on behalf of the IUCN Red List, but will now require re-evaluation. The Alor population is currently well isolated from Timor (c.100 km between sites), and these islands have never been connected. The populations have little chance of interbreeding and the authors of the BCI paper say they should be considered as independent, evolutionarily significant units. Further field surveys are needed on both Timor and Alor to capture birds, clarify taxonomic relationships using molecular approaches, and further define habitat use and conservation status.

Ocean sunfish beaches in the Netherlands


This is an ocean sunfish video.

Dutch radio station Unity FM reports, that this Monday 26 December 2011, an ocean sunfish beached on Schouwen island. By now, it is in Naturalis museum in leiden.

This mainly tropical fish is rare in the cold North Sea.

Saving Brazilian forest birds

SAVE Brasil sets the echoes of Conservation in the Serra do Urubu

Fri, Dec 30, 2011

Since 2004, SAVE Brasil (BirdLife in Brazil) has been working to conserve the last remaining forests in the Serra do Urubu, in the municipality of Lagoa dos Gatos, Pernambuco state, northeastern Brazil. The Serra do Urubu Important Bird Area (IBA BR074) is home to a rich and unique biodiversity, including two of the world’s most threatened birds: Alagoas Foliage-gleaner Philydor novaesi and Alagoas Antwren Myrmotherula snowi. Conservation work began with the purchase of a 362 hectare property, today known as the Pedro D’Anta Natural Heritage Private Reserve, which is adjacent to the Frei Caneca Natural Heritage Private Reserve. Combined, the two areas protect 1000 hectares of Atlantic Forest.

Belize coral and fish protection

Belize protected area boosting predatory fish populations

Herbivorous fish needed for reef recovery still lagging

A 14-year study by the Wildlife Conservation Society in an atoll reef lagoon in Glover’s Reef, Belize has found that fishing closures there produce encouraging increases in populations of predatory fish species. However, such closures have resulted in only minimal increases in herbivorous fish, which feed on the algae that smother corals and inhibit reef recovery.

The findings will help WCS researchers in their search for new solutions to the problem of restoring Caribbean reefs damaged by fishing and climate change.

The study appears in an online version of Aquatic Conservation: Marine and Freshwater Ecosystems. The authors include: Tim McClanahan, N.A. Muthiga, and R.A. Coleman of the Wildlife Conservation Society.

Barracuda, grouper & snappers

Specifically, the fishing closures have resulted in the recovery of species such as barracuda, groupers, snappers, and other predatory fish. Herbivorous fish such as parrotfish and surgeonfish, however, managed only slight recoveries, along with a small amount of the herbivory needed to reduce erect algae and promote the growth of more hard corals. This modest recovery of herbivorous fish has not been sufficient in reversing the degradation of the reefs by algae that have overgrown the reef and replaced the coral that once occupied 75 percent, but now represent less than 20 percent, of the seafloor cover. The authors note that a recent national-level ban by the Belizean government on the fishing of parrotfish-a widespread herbivorous species-may be the key to reef recovery, provided that the fishing ban is enforced and met with compliance. WCS provided valuable data through its monitoring program at Glover’s Reef to justify the landmark measure to protect reef grazers.

For anglers and boaters who regularly travel the coasts of Florida the great barracuda (Sphyraena barracuda) is a common sight. Surprisingly, however, very little is known about the early life stage of this ecologically and socio-economically important coastal fish: here.

Recent experiments conducted at the Australian Institute of Marine Science (AIMS) produced striking results, showing for the first time that corals hosting a single type of “zooxanthellae” can have different levels of thermal tolerance – a feature that was only known previously for corals with a mix of zooxanthellae: here.

Scottish marine discoveries in 2011


From the Daily Mail in Britain:

Found in British waters: The sea creature that lights up like a Christmas decoration

Rare and elusive species found in marine surveys
Includes prehistoric ‘brainless’ fish
Quill-like ‘sea pen’ lights up when touched

By Rob Waugh

Last updated at 2:36 PM on 29th December 2011

This phosphorescent sea pen was literally the highlight of a series of finds marine surveyors off the coast of Scotland announced in their annual report today.

The studies, using acoustic multi-beam scanners and hi-def cameras, captured several rare and elusive species, including the sea pen – so named because resembles a writer’s quill as well as a Christmas tree. The sea pen is a colony of seabed dwelling polyps that lights up when touched.

Other finds included the prehistoric ‘faceless and brainless fish’ Amphioxus – a modern representative of the first animals that evolved a backbone half a billion years ago.

The elusive, rarely seen Amphioxus was found in the waters off Tankerness in Orkney by marine surveyors this year. Instead of a brain – or face – the fish has a nerve cord running down its back.

One species of Amphioxus recently had its genome sequenced in an attempt to understand the origins of vertebrate life.

Vertebrate life and amphioxus are thought to have descended from a single common ancestor around 550 million years ago.

The species was unearthed in series of 15 marine surveys in 2011, covering over 2,000 square miles using acoustic multi-beam scanners and hi-def cameras.

Dozens of rare, strange species were found in Scottish waters.

Horse mussels were found off Noss Head in Caithness – this slow

The largest Horse Mussel bed in Scotland was revealed in waters near Noss Head, Caithness.

Known as ‘Clabbydhhu’ in Gaelic (translates as ‘enormous black mouth’) these slow-growing molluscs can live to nearly 50 years old.

Off the west coast, very rare Fan Mussels were found – at up to 48 cm long, this is Scotland’s largest sea shell.

Around the Small Isles more than 100 specimens were discovered, the largest aggregation in UK waters.

With golden threads likened to human hair so fine they can attach to a single grain of sand, seamen once believed they fed on drowned sailors.

Other finds included Flame Shell beds in Loch Linnhe, Argyll, a cryptic species only found in a very few west coast locations with bright orange feeding tentacles.
