Aquatic macrophytes capture trace elements from water and store them in their tissues, which make good biomonitors for these substances. But they also suspended particulate matter that could bias the concentration measurements moss tissues. To avoid this problem, many biomonitoring studies using mosses include a washing step sample preparation procedure. However, no data is available on quantit...

Size-selective mortality caused by fishing can impose strong selection on harvested fish populations, causing evolution in important life-history traits. Understanding and predicting harvest-induced evolutionary change can help maintain sustainable fisheries. We investigate the evolutionary sustainability of alternative management regimes for lacustrine brook charr (Salvelinus fontinalis) fishe...

The seasonal feeding pattern of sea-run brook trout Salvelinus fontinalis was studied from November to May 2010-2012 in Antigonish Harbour, Nova Scotia, Canada (45° 38' N; 61° 55' W). Sixty-three S. fontinalis (mean ± s.d. fork length = 330 ± 70 mm and mass = 536 ± 351 g) captured had fed predominantly on fishes (Fundulidae and Gasterosteidae). Percentage of empty stomachs was highest during au...
