Abstract

Survival is an important component of population growth rate. We use data from a 9-yr mark-recapture study to estimate annual and monthly survival probabilities of adult salamanders (Salamandra salamandra). Monthly survival probability was 0.98–0.99 and did not differ between summer and winter. Annual survival probability was 0.86. These estimates are similar to estimates for other salamander species. While other studies on Salamandra salamandra concluded that this species shows high movement rates, our results suggest very low movement rates.

Die Überlebenswahrscheinlichkeit ist eine wichtige Komponente der Wachstumsrate einer Population. Wir benutzen Daten einer Fang-Wiederfang-Studie, welche neun Jahre dauerte, um monatliche und jährliche Überlebenswahrscheinlichkeiten von adulten Feuersalamandern (Salamandra salamandra) zu schätzen. Die monatliche Überlebenswahrscheinlichkeit war 0.98-0.99 und war im Sommer und Winter gleich. Die jährliche Überlebenswahrscheinlichkeit war 0.86. Diese Schätzwerte sind vergleichbar mit denjenigen von andern Salamanderarten. Während andere Studien an Salamandra salamandra zum Schluss kamen, dass diese Art viel umher wandert, deuten unsere Ergebnisse auf sehr tiefe Wanderraten hin.

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.
