Double-crested Cormorants [PDF]
, 2016 The history of conflict between double-crested cormorants (Figure 1) and human interest in fisheries is long and convoluted. Following a low point in the 1970s, populations of cormorants expanded in North America, as did concerns about impacts on ...

Journal of Animal Ecology, EarlyView.Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Diet and heavy metal uptake by two top predator species in the Tees Estuary [PDF]
, 2006 The key aim of the thesis was to estimate metal uptake and its seasonal variation from the diet by two predators from the Tees Estuary, harbour seals, Phoca vitulina and cormorants, Phalacrocorax carbo.

Double-Crested Cormorants: Too Much of a Good Thing? [PDF]
, 2017 For centuries, people have viewed double-crested cormorants Phalacrocorax auritus negatively, and human persecution coupled with environmental contamination severely reduced numbers of cormorants throughout North America.

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea
Fisheries Oceanography, EarlyView.ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Restoration Ecology, EarlyView.Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...
