Description
  • Práce se zabývá srovnáním jednoho amerického a jednoho eurasijského druhu netopýra, které si jsou velmi podobné a byly dříve zařazovány do stejného podrodu. Zkoumané morfometrické znaky se týkají tělesných rozměrů, hmotnosti a zejména rozměrů na lebce a dentici. Kvantitativní data byla podrobena statistické analýze. Výsledky potvrdily nedávno publikovanou molekulárně genetickou studii, podle níž si tyto druhy nejsou příbuzné a jejich podobnost je důsledkem adaptace k podobnému způsobu života. Naše studie však ukazuje, že eurasijský Myotis daubentonii je více přizpůsoben ke sběru potravy z vodní hladiny než americký M. lucifugus. (cs)
  • The Palearctic Myotis daubentonii and the Nearctic Myotis lucifugus have traditionally been included into the subgenus Leuconoe due to their similar ecology and morphology. Recent molecular genetic analysis did not support this view since each of the two species was found to belong to another clade. The present paper is based on the analysis of eight external and 12 cranial characters in a sample of 158 M. daubentonii and 113 M. lucifugus, both species being represented by their nominate subspecies. ANOVA, t-test and principal component analysis (PCA) were used to test the variability and the impact of characters on interspecific differences. Significant sexual dimorphism was found mainly in M. daubentonii (females larger), hence in further analyses, males were separated from females. In both sexes, significant specific differences were found in most of the measurements, M. lucifugus having higher population averages than M. daubentonii. Only ca 50% of variability was observed on the first two PC axes
