Context-dependent parasite infection affects trophic niche in populations of sympatric stickleback species KU Leuven Instituut voor Natuur- en Bosonderzoek
How parasites alter host feeding ecology remains elusive in natural populations. A powerful approach to investigate the link between infection and feeding ecology is quantifying unique and shared responses to parasite infection in related host species within a common environment. Here, 9 pairs of sympatric populations of the three-spined and nine-spined stickleback fishes were sampled across a range of freshwater and brackish habitats to ...
