In the Syto13-stained samples we could differentiate bacteria with apparent high DNA (HDNA) content and bacteria with apparent low DNA (LDNA) content. HDNA bacteria, “live” bacteria (determined as such with the Molecular Probes Live/Dead Bac Light bacterial viability kit), and nucleoid-containing bacteria (NuCC) comprised similar fractions of the total bacterial community. Similarly, LDNA bacteria and “dead” bacteria (determined with the kit) comprised a similar fraction of the total bacterial community in one of the experiments. The rates of change of each type of bacteria during the microcosm experiments were also positively correlated between methods. In various experiments where predator pressure on ...

Our study analyses (1) the input of nutrients to river basins, and (2) the riverine export to coastal waters, for over 30 rivers in the Iberian Peninsula. Special emphasis is placed on nitrogen (N), although the export of phosphorus (P) and silicate (Si) is also assessed. We provide an overview of the temporal evolution (20-year time series) and the intraannual variability of nutrient fluxes for specific rivers and integrated coastal regions (the Mediterranean façade, the Atlantic front, and the Cantabrian front), and discuss the effects of sustained nutrient overload on land, freshwater, and marine coastal systems. For the latter, the eutrophication risk associated with river inputs is addressed by means of an indicator (Index of Coastal Eutrophication Potential, ICEP, Billen and Garnier, Mar Chem 106:148–160, 2007). Past and future trends in the context of increasing temperatures, increasing human pressures and regulation policies are discussedPeer Reviewe

Theoretical studies have shown that changes in these distributions (i.e., different μ values) are key to optimizing the long-term encounter statistics under certain searcher–resource scenarios. In particular, they predict the advantage of Lévy searching (μ ≈ 2) over Brownian motion (μ ≥ 3) for low-prey-density scenarios. Here, we present experimental evidence of predicted optimal changes in the flight-time distribution of a predator's walk in response to gradual density changes of its moving prey. Flight times of the dinoflagellate Oxyrrhis marina switched from an exponential to an inverse square power-law distribution when the prey ( Rhodomonas sp.) decreased in abundance. Concomitantly, amplitude and frequency of the short-term helical path increased. The specific biological mechanisms involved in these searching behavioral change...
