چکیده

Eucoleus schvalovoj Kontrimavichus, 1963 (Nematoda: Capillariidae) is redescribed. The original description of this species was brief and inadequate in that it was based on just a few specimens removed from the Eurasian otter, Lutra lutra (Linnaeus, 1758) in the Khabarovsk region, USSR. Detailed morphological study of several specimens of E. schvalovoj from the oesophagus of L. lutra from Spain revealed new characters, above all in males, and allows for a better characterisation of this species. Since its original description E. schvalovoj has only been recorded in Spain.

Organochlorine residue levels and bioconcentration factors in otters (Lutra lutra L.) from northeast Spain.

The dramatic reduction observed in the distribution of the Eurasian otter (Lutra lutra) during the latter half of this century has been largely attributed to pollution (MacDonald, 1991). Attention has focused on organochlorine compounds, in particular PCB (Mason 1989; Olsson and Sandegren 1991; MacDonald and Mason 1992). The scarcity of the otter, and protection afforded, has meant tissue sampl...

Eurasian otters, Lutra lutra, have a dominant mtDNA haplotype from the Iberian Peninsula to Scandinavia.

The Eurasian otter, Lutra lutra, has a Palaearctic distribution and has suffered a severe decline throughout Europe during the last century. Previous studies in this and other mustelids have shown reduced levels of variability in mitochondrial DNA, although otter phylogeographic studies were restricted to central-western Europe. In this work we have sequenced 361 bp of the mtDNA control region ...

Evaluating the Phylogenetic Status of the Extinct Japanese Otter on the Basis of Mitochondrial Genome Analysis.

The Japanese otter lived throughout four main Japanese islands, but it has not been observed in the wild since 1979 and was declared extinct in 2012. Although recent taxonomic and molecular phylogenetic studies suggest that it should be treated as an independent species, International Union for Conservation of Nature Red List considers it as subspecies of Lutra lutra. Therefore, the taxonomic s...
