We describe an approach to dynamically couple a fish bioenergetics-based population dynamics model to the NEMURO lower trophic level nutrient–phytoplankton–zooplankton model. The coupled models, denoted NEMURO.FISH and configured for Pacific herring (Clupea harengus pallasii) on the west coast of Vancouver Island, are capable of simulating the daily dynamics of the lower trophic levels and the daily average weight and numbers of individual herring in each of 10 age classes over multiple years. New recruits to the herring population are added each June based on either constant recruitment or dynamic recruitment generated from an environmental Ricker spawner–recruitment relationship. The …

Low reproductive success is thought to be a chief cause of the steady decline in numbers of piping plover (Charadrius melodus) that nest in the northern Great Plains. Surprisingly, few reproductive success data are published from alkali lakes in the region, where most breeding pairs of piping plover nest. During 1994 to 1997 we measured nest success and fledging rates of piping plovers at 32 alkali lakes across northwestern North Dakota and northeastern Montana, at the center of the species' breeding range in the Great Plains. Annual nest success and fledging rates averaged 38% (Mayfield estimate; 20 to …
