    last weeks field herping and fishing trip

    Hi,

    last week I went field herping in the "Duvenstedter Brook" near Hamburg/Germany. This is a large nature reserve.

    It was a sunny day without clouds and temperatures from round about 23 to 27 °C.

    Just look, what I did find that day:



    Zootoca vivipara



    Anguis fragilis



    Natrix natrix natrix baby



    Natrix natrix natrix

    Vipera berus



    Vipera berus melanistic


    Two days befor this field herping trip I went fishing with a friend of mine. This was the result of waking up at 2:30 in the morning and throwing out the bait at 5:00 in the morning



    Me and my first carpet ever. This guy weighed round about 17 pounds or 8,5 Kg.

    Best wishes,

    Hey,

    this was really a nice field herping trip. The pictures only show a small selection of the nicest animals I could find that day. The black european adder ist extremly rare and I was really very happy to find such a beautiful animal.

    And sorry for the carpet It has to be just a carp

    Best wishes,

    The melanistic adders aren't that rare up here in the north. Finnish adders are normally very dark even when they aren't melanistic.

    Daniel,
    Looks like a couple of great days... nice temperatures, plenty of herps, bright sunshine, and a big, fat carp! Did it croak likea frog when you took it out of the water ? Thanks for sharing your pictures. Do you think birds are eating the tails off those lizards or what?

    Stefan,
    The same principle applies with garters... the further North one goes, the more common melanistic garters become. It's said to improve their heat absorption, but that would be counter productive in warmer, Southern locales.

    So I've heard. There was a theory about them being able to leave the den earlier, too (mating earlier, feeding for a longer period), but I think some study shot that theory down fairly recently.

    I'm not surprised that a theory suggesting they could leave the den earlier and mate earlier would be shot down. Any organism that's unable to synchronize mating activity (in terms of location and timing) in a genus with such a limited reproductive period (particularly as one travels further north) is doomed to have impaired, not enhanced, reproduction. Moreover, black snakes in a winter's den wouldn't get the benefits of absorbing more solar energy, so again, it seems like a flawed theory.

    Compared to wild-type individuals, melanistics are more likely to enjoy the benefits of faster digestive rates, higher metabolic rate, better immunity, enhanced growth rates, and possibly greater activity levels earlier on sunny days. These attributes would provide a selective advantage in Northern locales.
