The mythical concept of eutrophication

  title={The mythical concept of eutrophication},
  author={Melbourne C. Whiteside},
Paleolimnologists frequently invoke the term ‘eutrophication’ for describing apparent enrichment phases in the history of a lake. I argue that this term is often used incorrectly and that alternative explanations can serve as more accurate descriptions. Increased organic content in the sedimentary record may result from increased nutrient availability (eutrophication), but it can also reflect decreased residence time of water, or changes in biotic interactions, or changes in lake morphometry… 

Palaeoenvironmental reconstruction of the recent history of Lake Chiuta Wetland, south Malawi

Understanding the environmental trajectory over the recent (ca. 200 years) of shallow inland water bodies is key to sustainable management of the fisheries industry that is facing severe challenges.

Documenting the History of Oxygen Depletion in Lake St. Croix, Minnesota, Using Chironomidae Remains in the Sedimentary Record

Lake St. Croix is a natural impoundment located at the southern end of the St. Croix River. Land use changes since European settlement (c. 1850) have resulted in nutrient runoff, eutrophication, and

Stratigraphy of Cladocera and Chironomidae in a core from a shallow North German lake

In the subfossil assemblages of chironomids and cladocerans significant changes were found during the late-glacial and postglacial development of a small, shallow North German lake. The successions

Distribution of chironomids (Diptera) in low arctic West Greenland lakes: trophic conditions, temperature and environmental reconstruction

1. Surface sediment samples of subfossil chironomid head capsules from 47 lakes in southern West Greenland were analysed using multivariate numerical methods in order to explore the relationship

Ecological correlates of net accumulation rates of Cladocera remains in lake sediments

Paleolimnological study of plant and animal microfossils is based on either relative abundances or net accumulation rates of various taxa. Interpretation of the latter is difficult because ecological

Holocene environmental history and climate of Råtåsjøen, a low-alpine lake in south-central Norway

The Holocene environmental history and climate are reconstructed for Råtåsjøen, a low-alpine lake in south-central Norway. The reconstructions are based on chironomids, diatoms, pollen, plant

Comparison of Cladocera-based water-depth reconstruction against other types of proxy data in Finnish Lapland

Lake depth is an important limnological attribute defining the structure and function of freshwater aquatic ecosystems. Lake levels have fluctuated and lake depths changed through the Holocene

Mid-to late-Holocene land-use change and lake development at Dallund S0, Denmark: synthesis of multiproxy data, linking land and lake

Multiproxy palaeoecological data for lake Dallund S0, Denmark, were synthesized to explore the link between changes in the terrestrial environment (from pollen, and sediment physical properties) with

Ecological Succession and Fragmentation in a Reservoir: Effects of Sedimentation on Habitats and Fish Communities

—While processes of depositional filling and ecological succession in natural lakes have been well described, these concepts are relatively new and seldom applied to reservoirs, especially at the



Species Diversity in Chydorid (Cladocera) Communities

It is sugested that species diversity of chydorids is controlled primarily by complexity of the thier habitat, the rooted aquatic macrophytes of lakes.

Long-Term Replacement Cycles in Cladoceran Communities: A History of Predation

Several lines of evidence suggest that these long—term substitutions of the waterflea Bosmina reflect a changing balance between planktivorous fishes and predatory copepods.

Species number and diversity increase log-linearly with time during the early development of a biocoenosis and this period ends with the attainment of a maximum diversity pattern.

Influence of Volcanic Eruptions on Xylem Growth Patterns

Xylem formed in four pine trees growing near Paricutin Volcano, Mexico, during 8 years of volcanic activity had several kinds of abnormalities, including narrow, wide, asymmetrical, and incomplete

Factors regulating phytoplankton production and standing crop in the world's freshwaters

A regression analysis of global data for freshwater phytoplankton production, chlorophyll, and various nutrient parameters revealed that a high proportion of the variance could be explained by annual phosphorus input (loading), once a simple correction for water renewal time was applied.

Ecology: The Experimental Analysis of Distribution and Abundance

This book discusses ecosystem dynamics under Changing Climates, which includes community dynamics at the community level, and factors that limit Distributions, which limit the amount of variation in population size.
