GPS tracking data of Lesser Black-backed Gulls and Herring Gulls breeding at the southern North Sea coast
In this data paper, Bird tracking - GPS tracking of Lesser Black-backed Gulls and Herring Gulls breeding at the southern North Sea coast is described, a species occurrence dataset published by the Research Institute for Nature and Forest (INBO). The dataset (version 5.5) contains close to 2.5 million occurrences, recorded by 101 GPS trackers mounted on 75 Lesser Black-backed Gulls and 26 Herrin...
متن کاملPhylogeography and colonization history of Lesser Black-backed Gulls (Larus fuscus) as revealed by mtDNA sequences
Because of the differential amplitude of climatic oscillations, species living at northern latitudes are subject to more frequent and more severe range oscillations than species at southern latitudes. As a consequence, northern populations should, on average, be phylogenetically younger and possess less phylogeographical structure than closely related taxa further south. To test these predictio...
متن کاملPopulation dynamics in lesser black-backed gulls in the Netherlands support a North Sea regime shift
Shamoun-Baranes & Camphuysen [1] made two main points in their critical appraisal of our recent article [2]: (i) that the Larus fuscus population increased in the Netherlands well before a mid 1980s regime shift in the North Sea and (ii) that population increases based on a simple prey type are difficult to imagine. These two comments give us the opportunity to deepen and complete our conclusio...
متن کاملVariation in Immune Parameters and Disease Prevalence among Lesser Black-Backed Gulls (Larus fuscus sp.) with Different Migratory Strategies
The ability to control infections is a key trait for migrants that must be balanced against other costly features of the migratory life. In this study we explored the links between migration and disease ecology by examining natural variation in parasite exposure and immunity in several populations of Lesser Black-backed Gulls (Larus fuscus) with different migratory strategies. We found higher a...
متن کاملFlexibility of habitat use in novel environments: insights from a translocation experiment with lesser black-backed gulls
Being faced with unknown environments is a concomitant challenge of species' range expansions. Strategies to cope with this challenge include the adaptation to local conditions and a flexibility in resource exploitation. The gulls of the Larus argentatus-fuscus-cachinnans group form a system in which ecological flexibility might have enabled them to expand their range considerably, and to colon...
