The alpine newt (Mesotriton alpestris) – more widespread in Duisburg than assumed. The results of the mapping of the herpetofauna by Klewen (1988, 1989) had suggested a complete absence of the alpine newt in the north and west of the city of Duisburg. In fact, evidence from nine areas (18 bodies of water in 12 grid fields: 1x1 km grid) is now known...

Possibilities of determining the native water frog taxa. Identifying water frogs (Pelophylax) is not easy, and many field herpetologists and conservationists do not dare to name the species or taxa (the edible frog is a hybrid). Because of the great similarity of the edible frog (Pelophylax esculentus) with its parent species, the Marsh Frog (Pelop...
Distribution and ecology of the Pool Frog (Pelophylax lessonae) – amphibian species of the year 2023. The Pool Frog is amphibian species of the year 2023 in Germany, Austria, Switzerland and Luxembourg. The article provides an overview of its characteristics, its distribution in Europe, its habitats and way of life, its threat and its protection. B...
There is a great biological sensation behind the apparently “ordinary” European water frog: an intricate reproductive system consisting of two parent species and a hybrid, plus several close relatives in southern Europe, the Near East and North Africa. It took a long time to decipher this complex and it still offers much material for further resear...
Before 2003, there were hardly any publications or other works on dragonfly fauna known for the area of the Western Ruhr Biological Station. The BSWR began taking inventory of the dragonfly fauna in its first year of operation. Individual areas, such as the species protection waterway created in 2005 on the edge of the Hiesfelder Forest, have even...
Until the mid-1990s, only 20 species were recorded in the western Ruhr area. Observations of at least 37 species are now known, some of which can be classified as probably carried over and unstable or not yet established. In fact, the density of observers has increased significantly since the 1990s, with the founding of the nationwide working group...
For at least two decades, European amphibians have been affected by the 'salamander plague', an emerging infectious disease caused by the invasive chytrid skin fungus Batrachochytrium salamandrivorans (Bsal) that originated from Asia. Resulting dramatic declines are well known from the European Fire Salamander, while the impact of Bsal on other Eur...
An online system for amphibian and reptile observation
Although the distribution of many amphibians and reptiles is broadly known, this is not true for all species and by no means for all regions of the world. Quite apart from that, we often know little about the actual areas and populations outside developed countries. There is still a lot to be d...

Basic considerations for the determination of green frogs (genus Pelophylax)
Plea for a pragmatic approach to the identification of the frogs of the genus Pelophylax. Until the end of the 1960s, only one (edible frog) or two species (edible frog, marsh frog) were distinguished, depending on the view. After it became known that there are two species...
Wall lizards have been expand their areal more and more in Central Europe for more than 40 years, and have successfully established many populations north of the known area boundary. The expansion has assumed rapid development in large parts, especially in the state of North Rhine-Westphalia. There are also quite a few documented releases of lizard...
