Comparative Parasitology, 2012
Abstract We examined the gastrointestinal parasite fauna of adult double-crested cormorants from breeding colonies on 4 very different lakes spanning a major ecotone from prairie to boreal forest in Saskatchewan, Canada. Our objectives were to document regional parasite fauna and identify potential differences based on breeding colony location.

Comparing Bioenergetics Models of Double-Crested Cormorant (Phalacrocorax auritus) Fish Consumption
Waterbirds, 2012Abstract. Double-crested Cormorants (Phalacrocorax auritus) began to recolonize Leech Lake, Minnesota, in the 1990s and reached 2,524 breeding pairs before control measures started in 2005. Walleye (Sander vitreus) recruitment concurrently declined, creating concern in the local community.

Morbidity and mortality events caused by avian paramyxovirus-1 (APMV-1) in Double-crested Cormorant (DCCO; Phalacrocorax auritus) nesting colonies in the US and Canada have been sporadically documented in the literature. We describe APMV-1 associated outbreaks in DCCO in the US from the first reported occurrence in 1992 through 2012.

SUMMARYHeart rate and dive behaviour were monitored in double-crested cormorants (Phalacrocorax auritus) during shallow (1 m) and deep diving (12 m), after breathing different gas mixtures, to investigate the role of depth and the accompanying changes in blood gas levels in cardiac and behavioural control during voluntary diving. Pre-dive heart rate in

Syncuaria squamata (Linstow) developed to the infective third stage in two species of freshwater ostracods (Cyclocypris ovum (Jurine) and Cypridopsis vidua (Muller)). At room temperature (19–21 °C) the first moult occurred 11 d and the second moult 18 d postinfection. In experimentally infected double-crested cormorants (Phalacrocorax auritus auritus (

Environmental Management, 2012
The context for this study is the management concerns over the severity and extent of the impact of cormorants on island flora in the recent past on Lake Erie islands. Accordingly, this study sought to quantify the nesting colonies' influence on coarse woody litter and how nest densities and litter depth may influence the herbaceous layer, the seed ...
