Long-Term Study of Benthos in Dardanelle Reservoir [PDF]
, 1994 Winter, spring, summer, and autumn samples were collected with a 15.24x15.24-cm Ekman grab from five stations on Dardanelle Reservoir, Pope County, Arkansas during the 24-year period from 1970-1993.

The jellification of north temperate lakes. [PDF]
, 2014 Calcium (Ca) concentrations are decreasing in softwater lakes across eastern North America and western Europe. Using long-term contemporary and palaeo-environmental field data, we show that this is precipitating a dramatic change in Canadian lakes: the ...

Algal food identity affects morphological anti‐predatory defense in Daphnia pulex
Limnology and Oceanography, Volume 70, Issue 5, Page 1109-1121, May 2025.Abstract Microcrustaceans of the genus Daphnia have evolved various inducible anti‐predator defenses; however, it is largely underexplored how the bottom‐up factor food quality may affect the extent of these defenses. A well‐studied example of an inducible defense is the deployment of neckteeth in Daphnia pulex in response to infochemicals from ...

Journal of Limnology, 2013 To determine the extent and timescale of predation impacts occurring in a historically fishless headwater lake near Sudbury, Canada, we surveyed the larval remains of the invertebrate predator Chaoborus and the pelagic cladoceran Bosmina, within a 210Pb ...

Density-dependent adjustment of inducible defenses [PDF]
, 2015 International audiencePredation is a major factor driving evolution, and organisms have evolved adaptations increasing their survival chances. However, most defenses incur trade-offs between benefits and costs.

Integrating the Bright and Dark Sides of Aquatic Resource Subsidies—A Synthesis
Ecology Letters, Volume 28, Issue 4, April 2025.Aquatic and terrestrial ecosystems are linked through the reciprocal exchange of materials and organisms. Aquatic‐to‐terrestrial subsidies can provide high contents of limiting resources that increase consumer fitness and ecosystem production, but they also may carry significant contaminant loads.

Is competition an interaction as relevant as predation for tropical planktonic cladocerans?
Acta Limnologica Brasiliensia, 2018 Aim To test the relevance of competition and predation for the two most abundant and frequent cladoceran populations, the medium-sized Ceriodaphnia richardi Sars, 1901 and the large-sized Daphnia gessneri Herbst, 1967, in a tropical shallow lake ...

Survey of the Macrobenthic Community in Ferguson Lake, Saline County, Arkansas [PDF]
, 2001 One hundred thirty benthic samples were collected on 33 visits to Ferguson Lake, Saline County, Arkansas, between May 1997 and October 2000. Sediments were visually examined and described, and some were returned to the lab for sediment oxygen demand (SOD)

Ecosphere, 2020 Inducible defense is adaptive when prey organisms cope with fluctuations of predation risk, and there exists ample variations of inducible defense both within a species and between species even in a single habitat. Daphnia, a freshwater zooplankton genus,
