Synthetizing hydrodynamic turbulence from noise: formalism and applications to plankton dynamics [PDF]
, 2003 We present an analytical scheme, easily implemented numerically, to generate synthetic Gaussian 2D turbulent flows by using linear stochastic partial differential equations, where the noise term acts as a random force of well-prescribed statistics.

Using the diel cycle of ocean microbes to better understand their biogeochemical functions
Limnology and Oceanography Letters, EarlyView.Abstract The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular ...

The effects of alewife (Alosa pseudoharengus) on zooplankton community structure in Depot Pond NH and a comparison of seven New Hampshire lakes [PDF]
, 1999 Physical, chemical and biological features of seven New Hampshire lakes were examined in September and October of 1997. Zooplankton communities exhibited evidence of “top-down” control in Milton Three Ponds (Depot, Norteast, and Townhouse Ponds), showing

Limnology and Oceanography Letters, EarlyView.Abstract Understanding the impacts of multiple environmental stressors on phytoplankton biomass is crucial for predicting marine ecosystem responses under global climate change. This study employed a sequential modeling framework integrating principal component analysis, generalized additive models, and artificial neural networks to improve predictions

Resolving the environmental factors that determine pond thermal refuge quality
Limnology and Oceanography Letters, EarlyView.Abstract Cold thermal refuges may mitigate detrimental effects of future climate warming; yet, pond ecosystems have been largely omitted from thermal refuge research despite being globally numerous and providing critical ecosystem services. We create a formal definition for pond thermal refuge quality, then operationalize this definition by measuring ...

Evaluation of climate change scenarios based on aquatic food web modelling [PDF]
, 2008 In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...

Regional variability in the trophic requirements of shelf sea fisheries in the Northeast Atlantic, 1973-2000 [PDF]
, 2005 Hydrographic, plankton, benthos, fisheries landings, and fish diet data from shelf sea areas in the Northeast Atlantic have been combined into an analysis of the foodweb structure and secondary production requirements of regional fisheries. Fish landings

Three's a crowd: The relationship among endoparasites, an epibiont and their Daphnia host
Oikos, EarlyView.In freshwater communities, organisms interact in a variety of ways, including predation, competition and parasitism. Parasites are ubiquitous, playing an important role in shaping freshwater communities. Endoparasites live within internal organs of their host, while ectoparasites, also known as epibionts, are confined to the external part of the host's
