Abstract

During tracking studies, the behaviour of animals may be affected by the tracking and tagging methods used, which may influence the results obtained. Our aim was to assess the impact of transmitter mass and the duration of tracking period on the body mass change (BMC) of two anuran species that were fitted with externally attached radio transmitters. Bufo b. spinosus and B. viridis were radio-tracked for three months during summer in the active tract of a large gravel-bed river (Tagliamento River, NE Italy). Our results demonstrated that transmitter mass and the duration of the tracking period did not affect BMC of the two anurans in their terrestrial summer habitats because methodological factors poorly predicted variation in BMC. Therefore, we encourage the use of tracking methods in amphibian ecology.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
