So Many Microbes, So Little Time, and So Little Money: Needs and Challenges in Developing a Global Network of Biological Resource Centers
Time Money Microbes
2015/7/29
When microbiologists first applied the tools of their trade to the oceans of the world, they quickly learned that water samples contained variable numbers of bacteria, depending on sample location and...
Human Development and Resource Use in the Coastal Zone:Influences on Human Health
Human Development Resource Coastal Zone Human Health
2015/7/23
Coastal watersheds and nearshore marine areas are the most valuable and dynamic places on Earth. Human population growth is great in these regions, which are home to some of the most sensitive habitat...
Environmental selection and resource allocation determine spatial patterns in picophytoplankton cell size
Environmental selection picophytoplankton cell
2014/4/2
Here we describe a new trait-based model for cellular resource allocation that we use to investigate the relative
importance of different drivers for small cell size in phytoplankton. Using the model...
Effects of seasonality and resource limitation on organic matter turnover by Chironomidae (Diptera) in southern Appalachian headwater streams
seasonality resource limitation Chironomidae in southern Appalachian headwater streams
2014/4/17
Despite their high abundance, secondary production, and known reliance on detrital material, the role of chironomids (Diptera) in fine particulate organic matter (FPOM) dynamics has not been well quan...
Upstream resource abundance determines the food searching behavior of a stream grazer: Effect of microalgal cues
Upstream resource abundance determines searching behavior
2014/4/18
To maximize their growth, grazers should shift their behavior to balance the cues from predators and
periphyton in the field. As a stream grazer seeks periphyton that are heterogeneously distributed,...
Resource levels, allometric scaling of population abundance, and marine phytoplankton diversity
Resource levels allometric scaling population abundance marine phytoplankton diversity
2014/4/21
We analyzed the relationship between population abundance and cell size in phytoplankton assemblages from coastal, shelf, and open-ocean environments. Our results show that across the entire size spec...

We analyzed the relationship between population abundance and cell size in phytoplankton assemblages from coastal, shelf, and open-ocean environments. Our results show that across the entire size spec...
Wood biofilm as a food resource for stream detritivores
Wood biofilm food resource stream detritivores
2014/4/22
Published assimilation efficiencies indicate that leaf detritus is a more nutritious food for stream invertebrates than wood. Some studies, however, suggest that wood and wood biofilms (epixylon) may ...
Mineral grains in caddisfly pupal cases and streambed sediments: Resource use and its limitation through conflicting resource requirements
Mineral grains caddisfly pupal cases streambed sediments conflicting resource requirements
2014/5/9
Sand and fine gravel in streambed sediments are considered to be an overabundant resource for caddisflies that build cases from it. However, larvae of Rhyacophila and Hydropsyche build pupal cases wit...
Predation as a factor mediating resource competition among rotifer sibling species
rotifer sibling species Predation
2014/5/14
The relevance of predation as a factor mediating the competitive interaction among ecologically very similar
species is investigated by experimentally analyzing the effect of the copepod predator Dia...
Resource quality effects on life histories of Daphnia
Resource quality effects life histories of Daphnia
2014/5/20
We investigated the changes in life histories imposed on the water flea, Daphnia magna, due to biochemical and mineral limitations. Phosphorus-deficient Scenedesmus obliquus were incubated with or wit...
Prey resource utilization by coexistent hydromedusae from Friday Harbor, Washington
Prey resource utilization coexistence hydromedusae Friday Harbor Washington
2014/5/27
Prey selection patterns were quantified for a sympatric group of hydromedusae from Friday Harbor, WA. Selection patterns varied between species, but were largely replicable between sample dates and re...
Grazer–resource interactions in the plankton: Are all daphniids alike?
resource interactions plankton all daphniidae alike
2014/6/10
Daphniids have long been considered to be uniquely effective grazers in the planktonic food web of lakes, but whether all daphniid species are equivalent in this functional role is less clear. In part...
Resource competition between sympatric sibling rotifer species
Resource competition sympatric sibling rotifer species
2014/6/9
Mechanisms underlying competitive interactions are important in understanding the structure of planktonic communities, particularly the coexistence of similar species. Here we present experimental res...
