Montseny brook newt bred in captivity

Saturday, August 4th, 2007

The attempts to save the Montseny brook newt (Calotriton arnoldi) from extinction have been bolstered by the successful breeding in captivity of the species. At most 1500 of these newts survive in a few fast flowing streams in Montseny in an area of 40km2, making them particularly vulnerable to fire and drought. So far just 7 larva have hatched in the breeding programme of the Centre de Recuperació de Fauna del Departament de Medi Ambient (El Periodico)

Of all the amphibians in Europe , the Montseny brook newt has the most limited area of distribution and it is also one of the most endangered species on the continent. More on the Montseny brook newt

Man survives viper bite

Tuesday, July 24th, 2007

A hiker has survived a viper bite in La Pedriza, Madrid, which would make it a Lataste’s viper or snub-nosed viper. 3-4 people probably die a year from viper bites in Spain, although this figure may now be lower due to the expansion in rural health facilities and the fact that there aren’t as many people working in the countryside.

Book on reptiles and amphibians in Spain

Tuesday, March 6th, 2007

27/02/2006 I recently bought Anfibios y Reptiles de la Peninsula Iberica e Islas Baleares (Guias Verdes) by Toni Aragon Rebollo, 2006. 39 euros or thereabouts. This is a very well organised and clearly written guide. Before the field guide itself, there is an ample introduction on the status of herps in Spain and a fascinating section on their place in Spanish folklore, from which I’ve quickly translated this on lizards.

In the north of the Peninsula, it was believed that lizards were friends of men, while snakes were related to women. They told that lizards would leap at women during their period (Translator’s note: My mother-in-law has told me about this). Similarly in Seville , geckos were said to chase after women. There also stories of lizards climbing into women’s vaginas while they slept. In the southeast there is the belief that if you come across a lizard with two tails and you put it in a plate scattered with flour, it will draw the winning numbers in the lottery (two-tailed lizards occasionally occur when a new one is regrown without the old having been totally severed). Another belief related to lizards tails is that they are a cure warts. This belief should be combated as the loss of its tail can cause great harm.

There is also lots information on the folklore around individual species in the field guide part. On the Turkish gecko we have for example:

Murcia they are known as pelás. This comes from the “powers” they are said to have. It is thought that if you misfortunate enough for a gecko to fall on your head you will go bald as a coot. In some villages just the mere spit from a gecko is enough to leave you hairless”.

All no doubt true, although biologists claim that geckos can’t spit. Thoroughly recommended. Good drawings and photos too.

Short-toed eagle video

Thursday, February 22nd, 2007

9-minute extract on the Short-toed eagle from the essential “El Hombre y la Tierra”, by Félix Rodrí­guez de la Fuente. As you will see in full gruesome detail , Águila culebrera its Spanish name (snake eagle) is well chosen. And as De la Fuente puts it in his indomitable style “even the lynx, the prince of the predators of the Mediterranean forest, stands in awe at such a feat” Remarkable.


New species in Spain

26/11/2006 150 new species are discovered every year in Spain

An interview with Mario García París of the Museo Nacional de Ciencias Naturales in today’s (El Pais) . I paraphrase.
“There are some 60,000 species of animals in Spain, of which some 40,000 are insects. And we are incapable of knowing how many are catalogued. A species is a group of animals which are genetically compatible. There are worms which look the same but are different species and frogs which are as similar as an egg to chestnut tree, but which can breed.
It is impossible to know how many species are still to be recorded. One knows when most of the biological wealth of a country has been recorded when the rate of discovery slows down. This does not seem to be likely in the short term in Spain. We’ve been discovering some 150 new species a year since the late 1970s. And this rate has continued unabated. Since 1978, 3,627 new species have been discovered in the Peninsula, with a further 1,417 in the Canaries at an almost constant rate of 150 a year. “In the distribution maps of species there are dark areas around Madrid, Barcelona and Las Hurdes, in Extremadura. The county of Las Hurdes appears because several people from the museum spend their holidays there”.
There are even big gaps in knowledge with groups such as amphibians despite the legions of amateur naturalists out and about recording them. “A year ago we discovered a new midwife toad which only lives in the fountains of villages. We called it Alytes obstetricans pertynas. “Pertinacious” because while most amphibians are becoming extinct, this one is resisting in human settlements”.
Spain because of its geographical position and the variety of its climate is particularly rich in biodiversity, but much of this being lost. “In the county you can’t hear anything anymore. Ten years ago you heard and saw lots of insects. Now they are spraying everything and all is quiet. When I look at my field notes from 15 years ago describing swarms of bugs I think I must have been exaggerating, but the truth is I was only describing what I saw. When we visit Morocco today we see animals everywhere, just as it was here years ago. If a Goya is burnt. It’s a national tragedy, because it cannot be replaced. The same is true for a species but nobody seems to care”. See also Montseny Brook Newt

Ladder snake on Monteserrat

Wednesday, February 21st, 2007

02/10/2006 I had an interesting walk on Montserrat the other day, where my batteries unbelievably failed just as I had the ladder snake to the left full in my sights. By the time I’d replaced them it had slithered away in seach of rodents and quiet. The Iberian wall lizard on the right was far easier prey. More on reptiles in Spain

Largest snake in Spain

Wednesday, February 21st, 2007

Montpellier snake by Stephen Daly. More great photos by him here below and on his site. As long as two metres, the Montpellier Snake is Spain’s largest snake and probably the commonest snake in the Mediterranean region and in Spain. This is despite the numerous deaths on the roads to which it is attracted in search of heat, and its persecution by man – it is seen as a threat to small game species and farm birds because of it size. On the contrary the Montpellier appears to be on the rise, as it easily adapts to humanised environs, which push out its competitor snake species. It is in theory one of the five venomous snakes in Spain , though the back position of its venom fangs means poison injection is unusual, and the latter reputedly weak. See also snakes in Spain quiz

Wryneck and horseshoe whipsnake

Wednesday, February 21st, 2007

This spectacular photo was sent to me by Clive and Sue who run guided walking tours in the Sierra de Grazalema . The wryneck lost the fight with the horseshoe whipsnake. It ate the chicks and the nest was abandoned. Some more great stuff from them in the next few days.
