Oceanic puffer, first time in the Netherlands


This is a video by a German diver on an oceanic puffer.

Oceanic puffers are a subtropical fish species.

They had never been recorded from the North Sea.

However, this week people from Ecomare museum on Texel island in the Netherlands discovered one; beached on the south of the island.

Piping plover conservation in Massachusetts, USA

15 August 2014

The threatened piping plover has been the focus of intensive conservation in Massachusetts. Thanks to continuing efforts by the many partners of the U.S. Fish and Wildlife Service and MassWildlife, the plover population here has come a long way since the shorebird was protected under the Endangered Species Act, from around 140 pairs when it was listed in 1986 to more than 650 pairs in 2013. Here are four examples of communities that are making a difference.

Plovers along the Atlantic Coast return to the Northeast in spring to breed and raise their young over the summer. If you’re visiting one of the region’s great beaches, look out for signage about this rare species. You can help us protect their nests and chicks:

-Respect all areas fenced or posted for protection of wildlife.
-Do not approach or linger near piping plovers or their nests.
-Please leave pets at home or on leash. Plovers perceive dogs as predators.
-Don’t leave or bury trash or food scraps on beaches. Garbage attracts predators that may prey upon piping plover eggs or chicks.
-Volunteer!

Rare Spanish sparrow in the Netherlands

Rare fungus discovery in Dutch Flevoland


Trichoglossum walteri

Recently, on black clayey soil, some black fungi were found in the Spijkbos woodland among fallen leaves. The finder sent them to a specialist to see if it were some earth tongues. They turned out to be the rare Trichoglossum walteri. This is only the second time that this earth tongue species has been found in the Netherlands.

27 new animal species discovered in Tanzania

The 2008 edition of the Exo Terra expedition headed for the Eastern Arc Mountains and the Southern Highlands of the Republic of Tanzania in East Africa. The main goal of this expedition was to map the amphibian and reptile biodiversity of these regions and to get a better understanding of the species inhabiting these complex ecosystems.

27 new species found in Tanzanian forests

A recent study revealed that 27 new vertebrate species have been found in the forests of Tanzania’s Eastern Arc Mountains. Of these, 23 were amphibians and reptiles. Of the total species that were identified in the region, the study found that there are 211 vertebrate species that are found only in the Eastern Arc Mountains, and 203 of them are found in Tanzania alone. These findings, says the study, re-enforce the importance of the Eastern Arc Mountains as one of the top locations on Earth for biological diversity and uniqueness.

“The Eastern Arc Mountains were already known for the unusually high density of endemic species,” explains Neil Burgess, a leading expert on Africa’s biodiversity and vice-chair of the TFCG, “however we lacked comprehensive data from at least six of the 13 mountain blocks.”

The study was conducted by an international team, and included researchers from the Tanzania Forest Conservation Group (TFCG) and MUSE-Science Museum in Italy, and was financed by Critical Ecosystem Partnership Fund (CEPF).

The Eastern Arc Mountains are an isolated chain of geologically ancient mountains that extend from southern Kenya to south-central Tanzania. According to scientists, the forest has existed on the mountains for more than 30 million years and was once connected to forests in the Congo Basin and West Africa.

Island-hopping in Galápagos: meet the world’s rarest tortoise and the birds of Española Island

10 October 2011

In the second part of his Galápagos island-hopping adventure, Andy Duckworth talks to naturalist guide Robert Naranjo, seeks out sea lions, a friendly hawk, dancing albatrosses and more prancing blue-footed boobies. He also meets Lonesome George, the last surviving Pinta Island tortoise and the rarest creature on the planet

Giant tortoise makes ‘miraculous’ stable recovery

By Jonathan Webb, Science reporter, BBC News

Where once there were 15, now more than 1,000 giant tortoises lumber around Espanola, one of the Galapagos Islands.

After 40 years’ work reintroducing captive animals, a detailed study of the island’s ecosystem has confirmed it has a stable, breeding population.

Numbers had dwindled drastically by the 1960s, but now the danger of extinction on Espanola appears to have passed.

Galapagos tortoises, of which there are 11 remaining subspecies, weigh up to 250kg and live longer than 100 years.

The study, based on decades of observations of the variety found on Espanola, was published in the journal Plos One.

Slow release

It offers some good news that contrasts with the tale of Lonesome George, the very last of the related subspecies found on Pinta, on the other side of the archipelago. George’s death, at the age of about 100, made international news in 2012.

Lead author Prof James Gibbs told BBC News the finding on Espanola was “one of those rare examples of a true conservation success story, where we’ve rescued something from the brink of extinction and now it’s literally taking care of itself”.

Prof Gibbs, from the College of Environmental Science and Forestry at the State University of New York (SUNY-ESF), said he felt “honoured” to be reporting the obvious success of the reintroduction programme, which the Galapagos Islands National Park Service commenced in 1973.

His team has found that more than half the tortoises released since that time are still alive, and they are breeding well enough for the population to plod onward, unaided.

“It looks like we can step back out of the picture,” Prof Gibbs said.

It is quite a contrast to the 1960s, when just 12 females and 3 males roamed the island.

“They were so rare at that point, they couldn’t find one another. Many of the females had lichens growing on their backs, and fungi, that indicated they hadn’t been mated in a very long time.”

Those animals were taken to an enclosure [on] another island, to concentrate on breeding. Over the subsequent decades, more than 1500 of their captive-raised offspring have been released on Espanola.

Competing for cacti

It wasn’t as simple as putting the tortoises back, however. Their problems began when feral goats were introduced in the 1800s and devoured much of the island’s vegetation, severely disrupting the ecosystem.

“They can literally turn a rich ecosystem into a dustbowl,” Prof Gibbs said.

The goats even learned to feast on very tall cactus plants, whose dropped pads are a key food source for the tortoises in the dry season.

“They would feast on the roots… and chew away at the bark, and eventually that would topple these cacti. And then they had an incredible buffet of maybe 500-1000 years of cactus growth, demolished in a week or two.”

Conservationists set about culling the goats in the 1970s and finally eradicated them in the 1990s.

Their legacy, Prof Gibbs discovered, remains.

Analysis of the island’s plant life and its soil show that it has seen a major shift to bigger, woodier vegetation in the 100 years since the goats started stripping the undergrowth.

These shrubs and trees are a problem both for the tortoises and for their summer food of choice, the cacti.

The trees even get in the way of an endangered albatross that breeds on the island, making it difficult for the big, ungainly birds to take flight.

“Population restoration is one thing but ecological restoration is going to take a lot longer,” Prof Gibbs said.

Dr Rebecca Scott, an ecologist who studies turtles at GEOMAR in Kiel, Germany, said the results showed how important it is to monitor reintroduction carefully.

“Reintroducing these large, keystone species, in combination with reducing the spread of invasive species, can really help return ecosystems to native state.

“This work highlights the merit of well-managed reintroduction programmes, but also of really monitoring how these animals do.”

Dr Gerardo Garcia, a herpetologist at Chester Zoo, agreed that the situation was complex and the programme had succeeded because of careful, long-term management.

“It’s a long process but it’s quite normal for it to take decades,” he told BBC News.

“Nothing gets released and stable in less than 20 or 30 years.”
