Study Shows Large Variability in Abundance of Viruses that Infect Ocean Microorganisms
Large Variability Viruses Infect Ocean Microorganisms
2016/2/22
Collecting and re-examining more than 5,600 estimates of ocean microbial cell and virus populations recorded over the past 25 years, researchers have found that viral populations vary dramatically fro...
Marine reserves help preserve genetic diversity after impacts derived from climate variability: Lessons from the pink abalone in Baja California
Marine reserve Overfishing
2015/12/11
Genetic diversity is crucial for the adaptation of exploited species like the pink abalone
(Haliotis corrugata), faced with threats from climate change, overfishing and impacts
associated with aquac...
Recent Advances and Future Visions:Temporal Variability of Optical and Bio-optical Properties of the Ocean
Recent Advances Future Visions Temporal Variability Optical and Bio-optical Properties the Ocean
2015/8/4
Ocean optics concerns studies of light and its propagation through the ocean, and bio-optics connotes biological effects on optical properties and vice versa. These two terms are so intertwined that t...
Examining shifts in zooplankton community variability following biological invasion
Examining shifts zooplankton community variability following biological invasion
2014/4/2
We examined 20 yr of zooplankton samples from Harp Lake for shifts in zooplankton variability following invasion by zooplankton predator Bythotrephes longimanus, using organism body size—as measured a...
Spring phytoplankton communities shaped by interannual weather variability and dispersal limitation: Mechanisms of climate change effects on key coastal primary producers
Spring phytoplankton communities shaped interannual weather variability dispersal limitation Mechanisms of climate change effects key coastal primary producers
2014/4/2
Spring bloom composition in the Baltic Sea, a partially ice-covered brackish coastal waterbody, is shaped by winter–spring weather conditions affecting the relative dominance of diatoms and a heteroge...
Metagenomic potential of microbial assemblages in the surface waters of the central Pacific Ocean tracks variability in oceanic habitat
Metagenomic potential microbial assemblages the surface waters the central Pacific Ocean tracks variability oceanic habitat
2014/4/17
Oceanic habitats may select for different organisms, thereby tuning genomic capabilities to local environmental conditions. To understand the relationship between microbial assemblage composition, fun...
Regulation of spatial and temporal variability of carbon flux in six hard-water lakes of the northern Great Plains
Regulation of spatial temporal variability carbon flux six hard-water lakes northern Great Plains
2014/4/17
Six hard-water lakes were sampled May-August for 14 yr in a 52,000 km2 catchment to identify the mechanisms that regulate the spatial and temporal variability of net atmospheric exchange of CO2 of lak...
Mapping the spatial variability of plankton metabolism using nitrate and oxygen sensors on an autonomous underwater vehicle
Mapping the spatial variability plankton metabolism using nitrate oxygen sensors autonomous underwater vehicle
2014/5/16
It is now possible to make highly resolved vertical (<1 m) and horizontal (3 m at constant depth and ~400 m when undulating from surface to 100 m) measurements of nitrate concentration in the upper oc...
Population dynamics of a freshwater calanoid copepod: Complex responses to changes in trophic status and climate variability
Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
2014/4/23
We present surface estimates of bacterial respiration, bacterial heterotrophic production (BHP), and bacterial growth efficiency (BGE), and their relationship with nutrient availability, along a troph...
Recruitment of intertidal invertebrates and oceanographic variability at Santa Cruz Island, California
Recruitment of intertidal invertebrates oceanographic variability Santa Cruz Island California
2014/5/13
To examine geographical variation in oceanographic forcing on larval delivery, we studied spatial and temporal variability in larval recruitment of mussels and barnacles in a key oceanographic region ...
Consequences of large temporal variability of zooplankton d15N for modeling fish trophic position and variation
Consequences of large temporal variability of zooplankton d15N modeling fish trophic position variation
2014/5/13
We use a temporal integration model (TIM) to determine how estimates of trophic variation, using δ15N, depend on consumer growth dynamics and temporal isotopic variation (δ15N) of food sources. Consum...
The North Atlantic climate and the northwestern Mediterranean plankton variability
The North Atlantic climate the northwestern Mediterranean plankton variability
2014/5/9
Climate variability across three distinct spatial scales and the interannual changes of planktonic copepods and jellyfish were studied from November 1966 to December 1993. The results obtained identif...
