Model of Fish Biomass Dynamics
Transactions of the American Fisheries Society, 1974Abstract A model of fish biomass dynamics is developed based on principles of physiology, population biology, and trophic ecology. The model is designed to incorporate measurable parameters for simulating seasonal changes in a natural population. All parameters were implemented for the bluegill (Lepomis macrochirus) and simulation results compared with

Microbial Biomass Dynamics in Tallgrass Prairie
Soil Science Society of America Journal, 1994Abstract The temporal dynamics and effects of burning, mowing, and N fertilization on microbial biomass (MBM) in tallgrass prairie were studied in a field experiment established in 1986. Microbial C (MC) and microbial N (MN), determined by the fumigation‐incubation procedure during the growing seasons of 1989 ...

The Dynamics of the Macromolecular Composition of Biomass
Journal of Theoretical Biology, 2001The biomass composition of microorganisms depends on the growth conditions. This study explores whether a two-component model can explain how the elemental and macromolecular composition of the biomass of bacteria varies with the specific growth rate. The model describes the rates at which microorganisms assimilate substrates into reserves and utilize ...

Testing for changes in biomass dynamics in large‐scale forest datasets
Global Change Biology, 2019Tropical forest responses to climate and atmospheric change are critical to the future of the global carbon budget. Recent studies have reported increases in estimated above‐ground biomass (EAGB) stocks, productivity, and mortality in old‐growth tropical

Biomass dynamic models are the simplest stock assessment models that are commonly used. Stock-recruitment models are in most cases used only as a part of a complete age-structured assessment. Only for semelparous species, and in practice only for Pacific salmon, can stock-recruitment models be used by themselves to evaluate alternative fishing plans ...

Remote Sensing of Forest Above-Ground Biomass Dynamics: A Review
ForestsRecent studies have primarily focused on estimating forest above-ground biomass (AGB) at single time points, with limited attention to temporal changes.

Price dynamics in Wisconsin woody biomass markets
Biomass and Bioenergy, 2014This study quantifies the potential impact of biofuel/bioenergy development on the pulpwood market in Wisconsin. Important demand and supply factors to take into account when quantifying the potential spillover effects include: (i) availability of regional forest residues, (ii) forest biomass demand of the Renewable Portfolio Standard (RPS) mandated by

Biomass dynamics of grassland vegetation in Kenya
African Journal of Ecology, 1988SummarySeasonal changes in plant biomass in the herb layer were measured at Nairobi National Park and Masai Mara Game Reserve in Kenya from January 1980 to February 1981. Plant biomass fluctuated in response to seasonal rainfall, and live biomass was correlated with rainfall and soil moisture at both locations.

Dynamic biomass char porosity during gasification: Model compared with data
Energy, 2023This investigation presents a new biomass char porosity model as a function of char conversion during gasification and compares it with entrained-flow data from poplar, corn stover and switchgrass particles reacting with H2O, CO2, and combinations of both at temperatures of 1050–1350 °C.

Deforestation and biomass fuel dynamics in Uganda
Biomass and Bioenergy, 2017Forests are, and will remain for decades to come, a critical source of domestic energy for households in East Africa. Deforestation threatens to alter the supply of biomass available to households. We use remote sensing and longitudinal household data to understand the relationship between agriculture-led deforestation and household energy choices in ...
