Deep seas cover more than half the planet and depend due to their lack of light on inflow of nutrients from above. Viruses play a critical role for the trophic supply of the deep-sea environments.

Most phytoplankton production occurs in the turbulently mixed surface layer of lakes and oceans. Environmental factors such as mixed layer depth and background turbidity substantially influence the availability of essential, production-limiting resources, i.e., light and nutrients. We tested the predictions of a dynamic model concerning the effects of water column mixing depth and background tu...

Delayed recruitment of microscopic stages in response to cyclical cues is critical to the population dynamics of many annual and seasonally reproducing perennial seaweeds. Microscopic stages may play a similar role in continuously reproducing perennials in which adult sporophytes are subject to episodic mortality, if they can respond directly to the unpredictable onset and relaxation of unfavor...

Lianas differ from trees in many life history characteristics, and we predicted that they are phenotypically more responsive to environmental variation than trees. We analyzed responsiveness to light and nutrient availability of five Bauhinia species (three lianas and two trees). Seedlings were grown in a shade house in two light regimes (5 and 25% of full sunlight) and two nutrient supply regi...

Traffic-light labelling has been proposed as a public health intervention to improve the dietary intakes of consumers. OBJECTIVES to model the potential impact of avoiding foods with red traffic lights on the label on the energy, total fat, saturated fat, sodium, and sugars intakes of Canadian adults. METHODS Canadian adults aged 19 and older (n = 19,915) who responded to the Canadian Commu...

We report on results of a microcosm experiment to study the interactive effects of elevated CO2, high organic and inorganic nutrient loading, and high irradiance on phytoplankton and bacterioplankton from the Mediterranean coastal ecosystem of the Alboran Sea. This experiment was part of the Group for Aquatic Productivity 9th international workshop and was conducted by Working Group 1 (WG1: Phy...
