STABLE ISOTOPE ANALYSIS REVEALS DIET NICHE PARTITIONING BETWEEN NATIVE SPECIES AND THE INVASIVE BLACK BULLHEAD (AMEIURUS MELAS RAFINESQUE, 1820)

Stable isotope analysis reveals diet niche partitioning between native species and the invasive black bullhead (Ameiurus melas Rafinesque, 1820)

The introduction and spread of alien fish species pose a major threat to native communities and ecosystem functioning in freshwaters.Black bullhead is one of the most successful invaders in European waters with several detrimental effects on native biota and ecosystems.In this study, we used stable isotope analysis to compare the body size and seas

Topologically cloaked magnetic colloidal transport

Abstract Cloaking is a method of making obstacles undetectable.Here we Membrane Switch cloak unit cells of a magnetic pattern squeezed into an otherwise periodic pattern from a magnetically driven colloidal flow.We apply a time-periodic external magnetic field loop to an ensemble of paramagnetic colloidal particles on the deformed periodic magnetic
