The hyperiid amphipod Brachyscelus rapacoides is a warm-water species associated with gelatinous zooplankton. In the Mediterranean it has been reported in association with Rhopilema nomadica in both Israel and Turkey. Here, we document the first record of B. rapacoides in Greek waters, representing the first confirmed record for Europe, based on both morphological examination and DNA barcoding of the mitochondrial COI gene.

Endemic pathogens continue to pose threats of recurring outbreaks, especially in agricultural settings. How these outbreaks unfold and what drives the variability in disease epidemics is less understood. We addressed this question in the Xanthomonas ‐tomato pathosystem by developing an integrated approach that linked the within‐field quantitative signature of local pathogen diversity to climatic conditions to explain variable...
