Zur Bedeutung des Geruchssinnes beim Nahrungserwerb von Kröten (Amphibia, Anura, Bufonidae): Versuche mit der Kreuzkröte (Bufo calamita Laur.)
1975
The influence of olfactory and visual prey stimuli on the feeding behaviour of toads was studied as well as their response to lasting olfactory cues. A further aim was to find simple methods for testing olfactory responsiveness in anurans. Subjects were 8 adult specimens of the European species Bufo calamita (natterjack) kept in captivity one year at least. The results point to the role of olfaction in these animals.
Amphibian survival compromised by long-term effects of chytrid fungus
2022
AbstractChytridiomycosis, the disease caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has been unambiguously implicated in the decline of amphibian populations worldwide. However, the impact of this devastating infectious disease can be difficult to gauge without empirical data on the population-level effects of Bd. Often, assessments of the amphibian chytridiomycosis panzootic are based primarily on expert opinions; as a result, declines in tropical areas are promptly attributed to Bd while its impact on temperate species not suffering from adult mass mortalities is frequently overlooked. Here, we investigated the survival probability in an amphibian species from a tempe…
Preliminary health screening and possible pathogen determination in aBufo bufo(Linnaeus, 1758) (Amphibia: Bufonidae) population
2010
The population of the common toad, Bufo bufo, on Jersey (Channel Islands, UK) has undergone a marked decline over recent years. Hypothesized causes for this decline include land use change, pollution, climate change and predation. We examined the carcasses of 97 wild adult common toads for gastrointestinal and pulmonary helminths. In addition, 31 adult toad carcasses were examined for the presence of ranavirus infection, and 212 wild common toads were examined for the presence of infection with the fungus Batrachochytrium dendrobatidis. Three nematode species Rhabdias bufonis, Aplectana macintoshii and Oswaldocruzia filiformis, and one species of cestode, Nematotaenia dispar, were identifie…
Description of a new species: Dorylaimus parasiticus , a parasite of amphibians in the Iberian Peninsula (Nematoda: Dorylaimida)
1995
Dorylaimus parasiticussp. nov. (Nematoda: Dorylaimidae) si described from the digestive tract and general body cavity of Salamandra salamandra, Rana perezi, and Bufo bufo, amphibians of the Iberian Peninsula (Spain). This is the first record of a member of the Order Dorylaimida size, a thick transversely striated body cuticle with 20 to 26 longitudinal ridges.
