Posted: 29 Jun 2006 It takes a while when I send anything to here. But we have got nice information about some of our reptile-and amphibian-species after we got license to mark and work with our creatures. Here is a one example picture about one female, nearby at hibernation place and female what donĘt move more than 3-5 meters since 17th of May and we believe it should be gravid. We are trying to follow different gravid females and we have a good start with different specimens. We have checking that places two to four times every week and of course, looking for other snakes from those populations. We have used capture-recapture methods with Vipera berus what should give interesting information to us. Of course, our work takes five years or more if needed and it contains another species as well. Timo Paasikunnas and Alina Kallio |

Posted: 29 Jun 2006 Sounds like a very intersting study Timo, please keep us informed of your findings. Gemma Fairchild, Independent Ecological Consultant |

Posted: 30 Jun 2006 Hey Timo, What other species do you mean? Zootoca vivipara or some cryptic Vipera taxon? g's, J. Jeroen Speybroeck http://www.hylawerkgroep.be/jeroen/ |

Posted: 30 Jun 2006 Another species, not so easy as V.berus, is Anguis fragilis which living closely and luckily partly in same area as that adder in last pictures. We are doing close research about flora and soil if their have a connect for microhabitat with A.fragilis in Finland. That would help to find a new population and doing inventory with that secret creature. Then Triturus(Lissotriton) vulgaris, we have doing research about migration between different small ponds and looking for route between hibernacula, breeding(aquatic time) ponds and area what their using at terrestrial time. In our license is for Natrix natrix too, but because it has so wide moving area, it is more difficult and takes time before we have a good result about that species.

Posted: 30 Jun 2006 HiTimo, Very interesting; hope that you can keep us updated. On another matter - don't know whereabouts you are in Finland, but do you know of the large den aggregations of V.berus near Helsinki Airport? (up to 200). It was my plan to go there and take photos for my book, but South Africa beckoned. Cheers 'I get my kicks on Route 62' |

Posted: 18 Jul 2006 Hello Armata, Surely we can check some hibernacula if you visit in Finland, I live in south and that isn't a problem. By the way, maybe we meet in Potchefstroom 24-27 November? We will be in there. Timo |

Posted: 06 May 2010 Well, I haven't been a very active member in Forum but now I'll try to write something about our research in situ in Finland. With adders, at that moment we have 67 hibernacula of adders in our research and every year we find more and, of course we following situation in old place. These many years has been showing clearly the most dangerous threat: traffic. 15 years ago when started counting snakes and searching they living area, every year 1-3% of adders was DOR. Nowadays 10-30% are DOR what I have found. It is sad when mark-recapture to found on the road and crushed by car. Of course, something good. This winter we had a lot of snow and very cold, many days were more than -30 C! Hibernacula were dry and under the snow, about 70 cm! Places looks good now and even only males were wake yet, only few females only at this time, many familiar specimens have found. Same winter was good for frogs, Rana temporaria and R.arvalis. Good amount of water in basin area, R.arvalis favourite breeding area. Have a nice spring, Timo |
