Effects of climate on size structure and functioning of aquatic food webs [PDF]

, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Factors associated with blooms of cyanobacteria in a large shallow lake, China

Environmental Sciences Europe, 2018
Background Eutrophication of freshwater systems can result in blooms of phytoplankton, in many cases cyanobacteria. This can lead to shifts in structure and functions of phytoplankton communities adversely affecting the quality of drinking water sources,

Long‐range transport of terrestrial particulate organic carbon to the open ocean by sediment resuspension

Limnology and Oceanography, EarlyView.
Abstract The transport of particulate organic carbon (POC) from land to deep‐sea sediments is a critical component of the global carbon cycle. However, the transport processes of terrestrial POC across continental shelves remain poorly understood due to the complexity of these systems.

Modeling Cell Populations Measured By Flow Cytometry With Covariates Using Sparse Mixture of Regressions [PDF]

arXiv, 2020
The ocean is filled with microscopic microalgae called phytoplankton, which together are responsible for as much photosynthesis as all plants on land combined. Our ability to predict their response to the warming ocean relies on understanding how the dynamics of phytoplankton populations is influenced by changes in environmental conditions.

Soil carbon dioxide levels control salt marsh alkalinity generation

Limnology and Oceanography, EarlyView.
Abstract Recent studies have highlighted salt marshes as hotspots for alkalinity generation and export to coastal waters. Several studies emphasize the critical role of anaerobic microbial metabolism as a major source of total alkalinity (TA) generation in marsh soils. However, the contribution of mineral dissolution to salt marsh TA generation has yet

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms

Limnology and Oceanography, EarlyView.
Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.

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 ...

Insight into diversity change, variability and co-occurrence patterns of phytoplankton assemblage in headwater streams: a study of the Xijiang River basin, South China

Frontiers in Microbiology
Phytoplankton has been used as a paradigm for studies of coexistence of species since the publication of the “paradox of the plankton.” Although there are a wealth of studies about phytoplankton assemblages of lakes, reservoirs and rivers, our knowledge ...

Size Class Dependent Relationships between Temperature and Phytoplankton Photosynthesis-Irradiance Parameters in the Atlantic Ocean

Frontiers in Marine Science, 2018
Over the past decade, a number of methods have been developed to estimate size-class primary production from either in situ phytoplankton pigment data or remotely-sensed data.

Competition between phytoplankton and bacteria: exclusion and coexistence [PDF]

N° RR-8038 (2012), 2012
Resource-based competition between microorganisms species in continuous culture has been studied extensively both experimentally and theoretically, mostly for bacteria through Monod and and Contois "constant yield" models, or for phytoplankton through the Droop "variable yield" models.
