Predicting the population consequences of human disturbance for Ringed Plovers Charadrius hiaticula: a game theory approach
Ringed Plover (Charadrius hiaticula) Science Article 2 abstract Human disturbance and its potential impacts upon bird populations are currently topical and contentious issues for conservationists. Although many studies have revealed a behavioural impact, or even direct effect on breeding success or survival, these cannot usually be extended to predict the impact on population size. Here […]
Different timing of autumn migration of two Ringed Plover Charadrius hiaticula subspecies through the southern Baltic revealed by biometric analysis
Ringed Plover (Charadrius hiaticula) Science Article 1 abstract Ringed Plovers were trapped in Puck Bay (southern Baltic) between 1983 and 2002 during autumn migration.

OVERHEAD WIRES REDUCE ROOF-NESTING BY RING-BILLED GULLS ANDHERRING GULLS
Ring-billed Gull (Larus delawarensis) Science Article 8 abstract The authors evaluated the effectiveness of overhead wires in reducing roof-nesting by ring-billed gulls(Larus delawarensis) and herring gulls (L. argentatus) at a 7.2 ha food warehouse in Bedford Heights, Ohio during1994-1995. In 1994, stainless steel wires (0.8 mm diameter) were attached generally in spoke-like configurationsbetween 2.4 m […]
