Article
Full-text available
The emergence of the chytrid fungus Batrachochytrium salamandrivorans (Bsal) represents a dramatic new threat to European amphibians. This skin pathogen causes skin lesions and ulcerations in European salamanders, eventually causing their death. Bsal first emerged in the Netherlands and Belgium where it caused mass mortality in populations of fire...
Article
Full-text available
The composition of cutaneous (skin-associated) bacterial communities of amphibians has been intensively studied in light of the potential of some of these commensal bacterial taxa to mitigate infection with the chytrid fungi Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal). However, surprisingly, the absolute densities in which th...

The increasing study of emerging wildlife pathogens and a lack of policy or legislation regulating their translocation and use has heightened concerns about laboratory escape, species spillover, and subsequent epizootics among animal populations. Responsible self-regulation by research laboratories, in conjunction with institutional-level safeguard...
Article
Full-text available
Phenotypic adaptation in terms of background color matching to the local habitat is an important mechanism for survival in prey species. Thus, intraspecific variation in cryptic coloration is expected among localities with dissimilar habitat features (e.g., soil, vegetation). Yellow-bellied toads (Bombina variegata) display a dark dorsal coloration...
Article
Full-text available
Dispersal is a central process in ecology and evolution with far reaching consequences for the dynamics and genetics of spatially structured populations (SSPs). Individuals can adjust their decisions to disperse according to local fitness prospects, resulting in context-dependent dispersal. By determining dispersal rate, distance and direction , th...

EAZA Best Practice Guidelines (Striped) fire salamander, Salamandra salamandra (terrestris) is the first version of the EAZA Best Practice Guidelines for this species. This guideline has evolved out of the growing concern for extinction of local fire salamander populations due to the introduction of the invasive chytrid fungus Batrachochytrium sala...
Article
The Near Eastern fire salamander (Salamandra infraimmaculata) reaches its southern distribution range in Israel. Although the population structure has been analysed in central Israel and at the southern distribution limit, we lack knowledge on populations in the northern area, such as along Mount Hermon. S. infraimmaculata occurs at Mt. Hermon alon...
Thesis
Chytridiomycosis, an emerging infectious disease caused by infection with the invasive chytrid fungus Batrachochytrium salamandrivorans (Bsal), is causing rapid population declines and extinctions in the hyper-susceptible European fire salamander (Salamandra salamandra). With Germany being the Bsal hotspot in Europe, one of the largest fire salaman...
Article
Full-text available
The chytrid fungus Batrachochytrium salamandrivorans (Bsal), recently introduced from Asia to Europe, causes mortality in numerous species of salamanders and newts and has led to catastrophic declines and local extinctions of the European fire salamander (Salamandra salamandra) in the Netherlands, Belgium, and Germany. Due to the continuous spread...
Article
Full-text available
The salamander plague, caused by the amphibian chytrid fungus Batrachochytrium salamandrivorans (Bsal), is one of the most devastating amphibian diseases, currently threatening the entire Western Palearctic caudate diversity with extinction. Apparently of Asian origin and recently introduced into Europe, Bsal is known from currently ca. 80 sites in...

Seit 2008 wurde in den südöstlichen Niederlanden ein dramatischer Einbruch der Feuersalamanderpopulation beobachtet. 2013 wurde mit der Beschreibung des Krankheitserregers die Ursache erkannt. Batrachochytrium salamandrivorans, kurz Bsal, ist ein Amphibien-Hautpilz, der vor allem für Feuersalamander, aber auch für Molche, eine große Gefahr darstell...
Article
Der Feuersalamander (Salamandra salamandra) gilt als eines der bekanntesten Amphibien in Deutschland. Die charakteristische schwarz-gelbe Färbung und das milchigweiße Gift, welches bei Gefahr über die Haut abgesondert wird, sind seine besonderen Kennzeichen. Die Kombination aus auffälliger Körperfärbung und Giftproduktion wird weithin als Indikator...
Article
Full-text available
Fire salamanders ( Salamandra salamandra) are conspicuously colored amphibians secreting a skin poison that contains unique steroid alkaloids such as samandarine (1) and samadarone (2), exhibiting toxic as well as antimicrobial activities. Because of their antipredatory and anti-infectious functions, alkaloids from Salamandra poison are of interest...

„Natur Natur sein lassen“ ist die Idee und das Ziel eines Nationalparks, was die Förderung und den Erhalt des für dieses Gebiet typischen Ökosystems und dessen natürlicher Vielfalt beinhaltet. Dieses Motto gilt insbesondere im Entwicklungs-Nationalpark Harz bislang schon für die Naturdynamikzonen (Kernzonen), welche sich selbst überlassen sind, d.h...

Full-text available
Infektionskrankheiten werden als eine der Hauptursachen des alarmierenden globalen Rückgangs von Amphibien angesehen. Seit Jahrzehnten verursacht der Amphibien-Hautpilz Batrachochytrium dendrobatidis (Bd) weltweit dramatische Bestandseinbrüche und -verluste, während ein weiterer Amphibien-Hautpilz namens Batrachochytrium salamandrivorans (Bsal) ers...
Article
In the face of the global biodiversity crisis, the monitoring of species richness and diversity is experiencing an increased demand entailing a raise in cost and time investment. The analysis of species-specific DNA fragments in environmental samples (eDNA) such as from water or soil, facilitate the molecular detection of species without the specif...

The emergence of the chyrrid fungus Batrachochytriutn salamandrivorans (Bsal) represents a dramatic new threat to European amphibians. This skin pathogen causes skin lesions and ulcerations in European salamanders, eventually causing their death. Bsal first emerged in the Netherlands and Belgium where it caused mass mortality in populations of fire...
Article
Full-text available
Protective coloration is a well-known predator avoidance strategy in prey species. Aposematic species often display a contrasting color pattern consisting of dark spots of different shapes and sizes on a bright background coloration. Both elements, background color and spots are expected to serve different purposes. While the ecological function of...

True salamanders of the genus Salamandra defend themselves with an alkaloid containing skin poison which supposedly acts binary as an efficient anti-predator and anti-microbial defense line. Due to the combination of skin poison with conspicuous colorations, many species of the genus are considered as aposematic. In this project, we aim to develop novel approaches for skin poison compound isolation and quantification. We are interested in testing the ecological roles of Salamandra skin poison as aposematic signal honesty or developmental origin of toxins. Most importantly we are aiming towards describing currently unknown compounds in the skin poison of Salamandra and in determining their biological functions.
