Pontogammarus robustoides has spread across Europe since the second half of the twentieth century. It is often regarded as a psammophilous and/or phytophilous species. We studied preferences of P. robustoides for 5 mineral substrata of different grain sizes, 5 plant species and 3 artificial plants differing in leaf shape. We tested 10 gammarid individuals in 24-h pairwise choice tests in darkened tanks. Adults selected stones of 27 ± 4.8-mm grain diameter, rather than smaller or larger objects… CONTINUE READING
