Bacterioplankton: a sink for carbon in a coastal marine plankton community.
Recent determinations of high production rates (up to 30 percent of primary production in surface waters) implicate free-living marine bacterioplankton as a link in a "microbial loop" that supplements phytoplankton as food for herbivores. An enclosed water column of 300 cubic meters was used to test the microbial loop hypothesis by following the fate of carbon-14-labeled bacterioplankton for ov...
متن کاملClimate shifts the interaction web of a marine plankton community
Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive (MAR) models of marine ...
متن کاملAssessing compliance: Active versus inactive trainees in a memory intervention
Extensive research on memory interventions has confirmed their success with older adults, but the individual difference factors that predict successful training outcomes remain relatively unexplored. In the current intervention, trainees were identified as active (compliant with training regimens) or inactive using trainer ratings based on attendance, homework completion, and class participatio...
متن کاملComparing Levels of Depression in Healthy Active and Inactive Elders versus Those with Knee Osteoarthritis Disease
Knee osteoarthritis can have negative effects on the physical and mental conditions, social and family relations, general health and positive feelings of elders. For example, severe limitation of motion and increased depression, which are results of this disease, can have negative impacts on elders. The purpose of this study was to compare the levels of depression in healthy active and inactive...
متن کاملDistribution of potentially pathogenic bacteria as free living and plankton associated in a marine coastal zone.
AIMS To determine the abundance of faecal and nonfaecal bacteria related to human and animal health, as free living or associated with small (>64 microm) and large (>200 microm) plankton, samples were collected monthly from the coastal zone at Messina (Italy). METHODS AND RESULTS Different enrichment and selective cultural methods were used to determine the abundance of bacteria in sea water ...
