A new research project aims to unravel the physical limits of cell size in budding yeast, with the ultimate goal of learning more about how cells, the fundamental units of life, modulate size control ...
Study Discovers Fundamental Unit of Cell Size in Bacteria
Fundamental Unit Cell Size Bacteria
2017/4/27
Biologists have long known that bacteria grow faster and bigger when the quality of nutrients becomes better, a principle in microbial physiology known as the “growth law,” which describes the relatio...
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...
Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
EFFECTS OF CELL SIZE ON AGNPS INPUTS AND PREDICTIONS
Distributed-parameter watershed models Agricultural Non-Point Source
2009/10/12
Distributed-parameter watershed models require division of a watershed into homogeneous areal units. The size of these units influences both model inputs and model accuracy. This study evaluated the r...
Scaling of phytoplankton photosynthesis and cell size in the ocean
phytoplankton photosynthesis cell size
2014/4/22
We have determined the scaling relationship between photosynthesis rate and cell size in natural
phytoplankton assemblages of contrasting marine environments. We found that phytoplankton photosynthes...
Effect of iron deficiency on diatom cell size and silicic acid uptake kinetics
iron deficiency diatom cell size silicic acid uptake kinetics
2014/5/19
We studied the silicic acid uptake kinetics of the pennate diatom Cylindrotheca fusiformis grown under a wide range of iron concentrations (from Fe-limiting to Fe-sufficient conditions) to assess the ...
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...
