Abstract Dredging is a catastrophic disturbance that directly affects key biological processes in aquatic ecosystems, especially in those small and shallow. In the tropics, metabolic responses could still be enhanced by the high temperatures and solar incidence. Here, we assessed changes in the aquatic primary production along a small section of low-flow tropical downstream (Imboassica Stream, Brazil) after dredging. Our results suggested that these ecosystems may show catastrophic shifts betwee...

La situation et l’histoire du Bassin caraïbe ont incontestablement favorisé le développement d’espaces fondés sur le principe de la dérogation permanente. Tolérés puis légalisés, ils jouent un double rôle: ils sont des zones de non-droit et cependant ils participent à la régulation du système monde. Ce double jeu peut-il néanmoins perdurer dans un monde ébranlé et instable?

Poly-ADP-ribose (PAR) is a polymer of up to 400 ADP-ribose units synthesized by poly-ADP-ribose-polymerases (PARPs) and degraded by poly-ADP-ribose-glycohydrolase (PARG). Nuclear PAR modulates chromatin compaction, affecting nuclear functions (gene expression, DNA repair). Diverse defined PARP cytoplasmic allocation patterns contrast with the yet still imprecise PAR distribution and still unclear functions. Based on previous evidence from other models, we hypothesized that PAR could be present i...
