Summary To gain a better understanding of the interactions among bacteria, viruses and flagellates in coastal marine ecosystems, we investigated the effect of viral lysis and protistan bacterivory on bacterial abundance, production and diversity [determined by 16S rRNA gene polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE)] in three coastal marine sites with different nutrient supplies in Hong...

Cloud cover increases the proportion of diffuse radiation reaching the Earth's surface and affects many microclimatic factors such as temperature, vapour pressure deficit and precipitation. We compared the relative efficiencies of canopy photosynthesis to diffuse and direct photosynthetic photon flux density (PPFD) for a Norway spruce forest (25‐year‐old, leaf area index 11 m 2 m −2 ) during two successive 7‐day periods in Aug...
