Modelling Responses of Herring Gull and Lesser Black Backed Gull Populations to Reduction of Reproductive Output: Implications for Control Measures

Seabirds? : what seabirds? : An exploratory study into the origin of seabirds visiting the SE North Sea and their survival bottlenecks

“…Yearly adult survival in Lesser Black-backed Gulls on Texel was found to be 0.91 (Camphuysen & Gronert 2012), the same value as found earlier for Lesser Black-backed Gulls in the United Kingdom (Wanless et al 1996). Adult annual survival in Lesser Black-backed Gulls on Texel showed considerable variation between years (ranging from 0.81-1.0) and might be declining due to increasing food shortage.…”

Equivalence relationships between stage-structured population models

“…This structure is commonly used for modelling animal populations. For example, recent examples include studies on birds [15][16][17][18], mammals [19][20][21][22], insects [23,24] and fish [25]. The model has a Fig.…”

Rapid population growth of Great SkuasCatharacta skuaat St Kilda: implications for management and conservation

“…38 This was reasonably successful for Herring Gulls but not for Lesser Black-backed Gulls Larus fuscus, with the difference attributed to the higher survival rate and lower colony philopatry of the latter species. 38 Great Skuas have an even higher adult survival rate than Lesser Black-backed Gulls 25 and, as this study has shown, a high immigration rate on Hirta, which suggests that this strategy would be even less likely to work at this colony. Equally, culling of breeding adults on a small scale would be unlikely to succeed because immigration plays such a major role in colony dynamics.…”
