AbstractThe Banc d'Arguin National Park (PNBA) in Mauritania, a globally significant biodiversity hotspot, faces growing threats from human activities and biological invasions. This study aimed to document marine invertebrate diversity in the PNBA and identify non-native and potentially invasive species. Samples were collected during expeditions in 2021 and 2022, using scuba-diving, drag dredging, and manual intertidal collection across depths of 0 to 20 meters.

In this work we investigate possible actions for antisymmetric two-tensor field models subject to constraints that force the field to acquire a nonzero vacuum expectation value, thereby spontaneously breaking Lorentz invariance. In order to assure stability, we require that the associate Hamiltonian be bounded from below. It is shown that this requirement rules out any quadratic action constructed only from the antisymmetric tensor field.
