Nutrient supply is a key bottom-up control of phytoplankton primary production in lake ecosystems. Top-down control via grazing pressure by zooplankton also constrains primary production and primary production may simultaneously affect zooplankton. Few studies have addressed these bidirectional interactions. We used convergent cross-mapping (CCM), a numerical test of causal associations, to quantify the presence and direction of the causal relationships among environmental variables (light…

Relative strength of top-down effects of an invasive fish and bottom-up effects of nutrient addition in a simple aquatic food web

TLDR
The results suggest weak bottom-up regulation in the experimental community, but strong top-down regulation, emphasizing the potential consequences of introducing non-native Western Mosquitofish to native aquatic ecosystems.

Contribution of zooplankton nutrient recycling and effects on phytoplankton size structure in a hypereutrophic reservoir

Consumer nutrient recycling influences aquatic ecosystem functioning by altering the movement and transformation of nutrients. In hypereutrophic reservoirs, zooplankton nutrient recycling has been

Trophic control changes with season and nutrient loading in lakes

TLDR
Across all lakes, top‐down effects were associated with nutrients, switching from negative in mesotrophic Lakes to positive in oligotrophic lakes, and this result suggests that zooplankton nutrient recycling exceeds grazing pressure in nutrient‐limited systems.

Energy‐based top‐down and bottom‐up relationships between fish community energy demand or production and phytoplankton across lakes at a continental scale

Fish community feeding and production rates may differ between lakes despite similar fish biomass levels because of differences in size structure and local temperature. Therefore, across‐lake

Seasonal variability and regulation of bacterial production in a shallow eutrophic lake

The seasonal variation of bacterial production (BP) in a shallow, eutrophic Lake Kasumigaura was clarified from 2012 to 2016. During the studied period, BP fluctuated from 1.9 to 138 μg C L−1 d−1.

Seasonal variation and drivers of zooplankton, macroinvertebrate and littoral fish communities from irrigation ponds in a semi-arid region in the Eastern Cape (South Africa)

Irrigation ponds are increasingly abundant globally, particularly in water-stressed countries with limited natural surface waters, yet knowledge of their ecology is limited. Here, we assessed

Trophic gauntlet effects on fisheries recovery: a case study in Sansha Bay, China

ABSTRACT Low biological productivity causes ecosystem energy deficiency. Sansha Bay is an important spawning and nursery ground for migratory fish in the East China Sea (ECS). There is significant

Impact of dissolved organic carbon , phosphorus , and grazing on phytoplankton biomass and production in experimental lakes

Phytoplankton biomass and production in lakes tend to be increased by phosphorus input and decreased by grazing or high levels of colored, dissolved organic carbon (DOC). We estimated and compared

TROPHIC CASCADES AND COMPENSATION: DIFFERENTIAL RESPONSES OF MICROZOOPLANKTON IN WHOLE-LAKE EXPERIMENTS

TLDR
Small-scale, short-term ex- periments and larger-scale comparative analyses may be inadequate for assessing the strength of trophic interactions, and the potential for community-level responses, not well assessed except at the ecosystem scale, may alternatively dampen or enhance the impacts of Trophic cascades in food webs.

Zooplankton abundance in the pelagic region of Lake Kasumigaura (Japan): monthly data since 1980

TLDR
The abundance of zooplankton taxa (crustaceans and rotifers) that were recorded monthly, from January 1980 to September 2015, at two stations on Lake Kasumigaura, a shallow eutrophic lake that is the second largest lake in Japan.

Lake Eutrophication and Plankton Food Webs

The plankton food web comprises microscopic organisms that transport carbon and energy from producers to consumers in the water column of aquatic ecosystems. In lakes, the food web includes bacteria,

TLDR
It is suggested that microzooplankton grazing and nutrient mineralization are driving forces affecting bacteria and phytoplankton dynamics, playing important roles in carbon and nutrient transfer to upper trophic levels even in pelagic freshwater systems containing abundant crustaceans.
