The Mississippi River delta is a rich ecosystem of barrier islands, estuaries, and wetlands that’s home to a diverse mix of wildlife — as well as more than 2 million people. Over the past few decades,...
Intraspecific scaling of mass to length in pelagic animals: Ontogenetic shape change and its implications
Intraspecific scaling of mass length in pelagic animals Ontogenetic shape change its implications
2014/4/4
Intraspecific relationships between body mass (M) and length (L) are widely reported using the equation M = aLb. The power term (b) holds fundamental information on how body proportions change with in...

On the Equilibrium Shape of the Thermocline in a Shore Zone
Equilibrium Shape Thermocline Shore Zone
2009/3/9
The typical spring thermal regime of Lake Ontario shows a thermocline surface of either a “wedge” or of a “lens” shape persisting in the shore zone for a considerable period. The summer regime is char...
The mean ocean density field resembles the state of maximum entropy with given values for the upper water mass, total energy and potential enstrophy. Numerical experiments confirm that the thermocline...
Plastic phenotypes of antennule shape in Bosmina longirostris controlled by physical stimuli from predators
antennule shape Bosmina longirostris controlled
2014/4/22
Three antennule morphotypes in the small cladoceran Bosmina longirostris have been considered to be
hereditarily rigid phenotypes. However, we found that monoclonal populations of Bosmina collected f...
Molecular quantification of differential ingestion and particle trapping rates by the appendicularian Oikopleura dioica as a function of prey size and shape
Molecular quantification of differential ingestion particle trapping rates the appendicularian Oikopleura dioica function of prey size and shape
2014/4/22
To investigate whether particles are ingested or merely trapped in the house of the appendicularian Oikopleura dioica, we developed a real-time quantitative polymerase chain reaction (qPCR) assay and ...
Assessment of the relationships between dominant cell size in natural phytoplankton communities and the spectral shape of the absorption coefficient
Assessment of the relationships dominant cell size in natural phytoplankton communities the spectral shape of the absorption coefficient
2014/5/26
Size-fractionated chlorophyll concentration and phytoplankton absorption spectra were compared for a wide variety of natural communities. We found that, in general, when phytoplankton abundance increa...
Herbivory and irradiance shape periphytic architecture in a Swiss alpine stream
Herbivory irradiance shape periphytic architecture a Swiss alpine stream
2014/6/17
The effects of herbivory and light on epilithic periphyton from Minor Creek (2,200 m above sea level), a Swiss alpine stream, were examined by manipulating light intensity and the densities of two abu...
