A growing number of studies have been investigating the influence of contemporary environmental factors on population genetic structure, but few have addressed the issue of spatial patterns in the variable intensity of factors influencing the extent of population structure, and particularly so in aquatic ecosystems. In this study, we document the landscape genetics of northern pike (Esox lucius...

PETRINEC, Z., S. NEJEDLI, S. KUŽIR, A. OPAČAK: Mucosubstances of the digestive tract mucosa in northern pike (Esox lucius L.) and european catfish (Silurus glanis L.). Vet. arhiv 75, 317-327, 2005. ABSTRACT The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described.

background: mercury (hg) is a major environmental contaminant due to its global ubiquity, tendency to bioaccumulate, and toxicity in wildlife. mercury accumulation in wetlands threatens critical breeding and foraging habitats of many fish and wildlife species. in this study, mercury concentrations were detected in different tissues of pike. methods: to achieve these purposes, 58 pikes (esox luc...
