The role of industrial fisheries and oceanographic change in the decline of North Sea black‐legged kittiwakes
TLDR
This study shows that adequate monitoring of the effect of a fishery or of environmental change on seabird populations needs to include survival as well as breeding success.
Scale‐dependent climate signals drive breeding phenology of three seabird species
TLDR
This work tested the hypothesis that regulation of breeding onset should reflect the scale at which organisms perceive their environment by comparing phenology of three seabird species at a North Sea colony, and found correlations among climate patterns at different scales are likely to change in the future.
Low energy values of fish as a probable cause of a major seabird breeding failure in the North Sea
TLDR
Poor food quality appeared to be the proximate cause of seabird breeding failure in 2004 giving support to the 'junk-food' hypothesis, which will be particularly sensitive to reductions in the energy value of food items.
Subantarctic Macquarie Island: Environment and Biology.
TLDR
This book discusses the history and present situation of the Isle of Man, as well as its flora and fauna, and some of the animals and plants that have been introduced to the island over the centuries.
Modelling responses of herring gull and lesser black-backed gull populations to reduction of reproductive output: implications for control measures.
TLDR
Limiting reproductive output can be an effective method of control for herring gulls, but not for lesser black-backed gulls; and on the basis of current information on vital rates it is possible to predict future population trends of herring Gills,but not lesser black backed gulls.
Reproductive Senescence in a Long‐Lived Seabird: Rates of Decline in Late‐Life Performance Are Associated with Varying Costs of Early Reproduction
TLDR
Investigation of factors influencing the rate of reproductive senescence in a long‐lived seabird, the common guillemot Uria aalge, demonstrates for the first time in a wild bird population that increased rates of senescences in reproductive performance are associated with varying costs of reproduction early in life.
ASPECTS OF THE BREEDING BIOLOGY OF THE GULLS: LARUS ARGENTATUS, L. FUSCUS AND L. MARINUS
Summary Minimal weights of testes in Larus argentatus, L. fuscus and L. marinus were found to occur during November and December, and minimal ovary weights between August and January. Details are
The demographic impact of extreme events: stochastic weather drives survival and population dynamics in a long-lived seabird.
TLDR
This work estimated first-year, second-year and adult survival based on 43 years of ringing and dead recovery data from the Isle of May, Scotland, using recent methods to quantify temporal process variance and identify aspects of winter weather linked to survival.
Divorce in the long-lived and monogamous oystercatcher, Haematopus ostralegus: incompatibility or choosing the better option?
TLDR
The increase in reproductive success with duration of the pair bond for female first-time breeders and divorced females (but not for widowed females) may be linked to an increase in breeding age of the female, instead of a re-bound from initial inefficiency in reproduction with the new mate.
Effect of wintering area and climate on the survival of adult Atlantic puffins Fratercula arctica in the eastern Atlantic
TLDR
The relationship between survival and sea temperature was positively correlated with the effects of sea temperature on recruitment of the Atlantic puffin's main prey species, the lesser sandeel Ammodytes marinus, the herring Clupea harengus and the capelin Mallotus villosus.
