Ecosystem functions across trophic levels are linked to functional and phylogenetic diversity.

PLoS ONE, 2015
In experimental systems, it has been shown that biodiversity indices based on traits or phylogeny can outperform species richness as predictors of plant ecosystem function.

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Environmental variables and plankton communities in the pelagic of lakes: enclosure experiment and comparative lake survey [PDF]

, 2005
Most primary production of lakes and oceans occurs in the well-mixed surface layer that is subject to strong seasonal and geographical variation. With increasing mixed surface layer depth average light supply and specific nutrient supply decrease and so ...

The use of acoustic doppler current profiler acoustic backscatter to develop a regional zooplankton indicator for temperate marine ecosystems

Ecological Indicators
Zooplankton are important prey in ocean food webs, linking primary producers to higher trophic levels; understanding their biomass is important to understanding ecosystem state and managing commercial fisheries accordingly.

Intraguild Predation Dynamics in a Lake Ecosystem Based on a Coupled Hydrodynamic-Ecological Model: The Example of Lake Kinneret (Israel)

Biology, 2017
The food web of Lake Kinneret contains intraguild predation (IGP). Predatory invertebrates and planktivorous fish both feed on herbivorous zooplankton, while the planktivorous fish also feed on the predatory invertebrates.

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Reducing establishment rates of non-indigenous zooplankton in constructed waters [PDF]

, 2010
Understanding the mechanisms that facilitate the establishment of non-indigenous species is imperative for devising techniques that will assist in reducing the establishment rates of non-indigenous species.
