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.

Limnology and Oceanography, EarlyView.Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

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 ...

Trophic strategies of freshwater nanoflagellates under variable run‐off scenarios
Limnology and Oceanography, EarlyView.Abstract Terrestrial run‐off is increasing in temperate lakes due to climate change and can lead to loading of colored dissolved organic matter (cDOM) and nutrients, thus reducing light availability and increasing carbon, nitrogen, and phosphorus. Run‐off events are highly irregular, resulting in temporal resource variability that may determine the ...

Use of ordination and classification procedures to evaluate phytoplankton communities during Superflux II [PDF]
Cluster analysis and an ordination procedure were performed on two data matrices to investigate real and environmental spatial relationships. Multiple regression analysis was used to relate the measured environmental variables to the phytoplankton ...

Recent progress in the identification and determination of freshwater phytoplankton in the natural environment [PDF]
, 1997 The biomass of the phytoplankton and its composition is one of the most important factors in water quality control. Determination of the phytoplankton assemblage is usually done by microscopic analysis (Utermöhl's method). Quantitative estimations of the

Smaller phytoplankton size‐groups control the stoichiometry of the autotrophic community
Limnology and Oceanography, EarlyView.Abstract In the marine environment, the prevailing paradigm is that larger organisms like diatoms are primary contributors to phytoplankton stoichiometry. Numerous studies investigated the stoichiometry of phytoplankton groups or total community but its dynamics among different size‐groups are not resolved.

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

Antagonistic and synergistic responses to solar ultraviolet radiation and increased temperature of phytoplankton from cenotes (sink holes) of the Yucatán Peninsula, México [PDF]
, 2015 Cenotes (sink holes) are karstic formations characteristic of the Yucatán Peninsula and are the main source of fresh water in the region. Because of their tropical location, they receive high levels of solar radiation and are exposed to high temperatures.

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.
