        Partial niche partitioning in three sympatric gull species through foraging areas and habitat selection

        Author: O'Hanlon, N.J., Clewley, G.D., Johnston, D.T., Thaxter, C.B., Langlois Lopez, S., Quinn, L.R., Boersch-Supan, P.H., Masden, E.A., Daunt, F., Wilson, J., Burton, N.H.K. & Humphreys, E.M.

        Published: 2025

        GPS tracking of three large gull species from the Isle of May, Scotland, revealed overlap in foraging habitats used during the breeding season, but differences in the where the three species foraged, and the strength of their preference for particular habitats, especially landfills, urban and coastal habitats.

        The genomic signature of demographic decline in a long-distance migrant in a range-extreme population

        Author: Day, G.W., Bolderstone, T., Conway, G., Cross, T., Davis, T., Dolan, M., Greening, M., Neale, C., Nicholson, I., Nicholson, K., Ward, A., Ward, N., Fox, G., Hipperson, H., Maher, K., Thompson, J., Tucker, R., Waters, D., Durrant, K., Burke, T., Slate, J. & Arnold, K.

        With increasing sophistication, genetic techniques and analyses are allowing us to delve deep into the past to show how prior environmental or demographic change has influenced species’ present day populations. This is particularly useful for scarce species that are difficult to observe and occupy remote habitats. In many species, large scale reduction in habitat availability has impacted their breeding distribution, which has been exacerbated by habitat fragmentation. Once widespread species become localised and the remaining breeding birds become increasingly isolated, this can result in reduced genetic diversity. This is case the Nightjar, a little-studied species, which has specialised habitat requirements and is located at the western edge of the European range.
