In Britain, L. l. lutra populations have greatly recovered over the last 35 years and are now present in every county (Crawford 2010). In Southeast Asia, L. lutra occurs sympatrically with the smooth-coated otter, and the Asian small-clawed otter. The average observed heterozygosity was (Ho = 0.50) with the lowest observed heterozygosity in Denmark (Ho = 0.35) and highest observed heterozygosity in Belarus, Finland, Latvia, and Sweden (Ho > 0.65) (Mucci et al. In Europe, a clear latitudinal gradient in diet composition occurs, where the diet of northern European L. lutra is primarily piscivorous and that of Mediterranean L. lutra relies less on fish and more on aquatic invertebrates and reptiles (Clavero et al.

L. In Germany, Norway, and mainland Shetland, subadults and adults comprise 8.5–33% and 14.0–43%, respectively, of the population, whereas juveniles represent 31.7–42.0% of the population (Ruiz-Olmo et al.

Though more abundant in lower altitudinal areas, L. l. lutra may also be found in the midst of mountainous habitats in European countries as well as in Tibet at 4,120 m (Ruiz-Olmo 2007). Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) .

Mean (± SE) energy expenditure during swimming ranged from 10.3 ± 3.3 W/kg at speeds of 0.5 m/s to 14.8 ± 4.5 W/kg at speeds of 1.5 m/s (Pfeiffer and Culik 1998). A.

See above. Lutra lutra is sexually dimorphic in that males are 50% larger than females (Larivière and Jennings 2009). The upper lip, the cheeks and the throat are more or less whitish and the ears are edged with light brown.

However, the relative frequency of fish prey varies with elevation where S. trutta was the dominant prey at elevations > 500 m and cyprinids were the dominant prey at elevations < 500 m (Ruiz-Olmo 2007).
