TL;DR: Differences in diel activity patterns and drift behaviour of preys, as well as differences in the prey size, are important adaptive features that may reduce the inter-specific competition in the fish community and permit the partitioning of food that allows coexistence.

TL;DR: Results show that downstream migration occurs between October and May with a peak in March, and suggest that part of the postmetamorphic lampreys start the hematophagous feeding in the river, with a special affinity for anadromous species, probably because of their larger size.

TL;DR: It is suggested that at least a portion of the sea lamprey population can reach adult size in 1 yr of hematophagous feeding, and a period between completion of metamorphosis and reproduction of 1.5 yr (18 to 20 mo).

TL;DR: A detailed analysis of introductions of those species with records after 1900 present in both areas shows that delays were up to 100 years for species introduced on the Iberian Peninsula at the beginning of the twentieth century, but the tendency adjust to a decreasing linear regression, with species introduced after 1995 being almost immediately present in Galicia.

TL;DR: The brown trout (Salmo trutta) is a species of Eurasian origin, but at has become naturalized in many other parts of the world and it has an outstanding socio-economic importance, both in commercial and sport fisheries.
