Physical measures to inhibit planktonic cyanobacteriae [PDF]
, 1992 In a small lake, intermittent destratification was installed after several other physico-chemical and physical in-lake therapy measures (phosphorus immobilization, permanent destratification) had been tested without great success.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Nutrient Addition Effects on Phytoplankton Communities in the Amazon River Plume [PDF]
The types and abundance of phytoplankton is largely controlled by availability of sunlight and bioavailable nutrients. Phytoplankton require essential nutrients including nitrate, phosphate, and silicate to grow, so understanding the role of these ...

A quantitative analysis of the phytoplankton of the Gulf of Panama II. On the relationship between C14 assimilation and the diatom standing crop [PDF]
, 1965 ENGLISH: The Inter-American Tropical Tuna Commission has maintained a hydro-biological station in the Gulf of Panama located at 8°45'N, 79°23'W in connection with their ecological investigation of the anchoveta (Cetengraulis mysticetus), a tuna baitfish (

, 2023 Between 2015 and 2019 plankton functional groups experienced significant changes in abundance, reflecting a continuation of long-term trends. Larvae of benthic invertebrates increased, while other groups mostly decreased. Observed changes were primarily linked to rising temperatures within offshore areas in the North-East Atlantic, and to nutrients in ...

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility
International Journal of Urban and Regional Research, EarlyView.Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

Investigating exudate- and habitat-mediated effects of phytoplankton on lake bacterial community dynamics [PDF]
Correlated patterns of abundance, activity, and composition are commonly observed between phytoplankton and bacterial communities. There are a number of potential explanations for correlated dynamics.

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.
