Limnology and Oceanography: Methods, EarlyView.Abstract The integration of high‐throughput image–based flow cytometry into routine phytoplankton assessment requires rigorous evaluation against established microscopy techniques. As method agreement is often site‐ and species‐specific, case‐by‐case validation is essential to successfully adopt emerging methods.

River Research and Applications, EarlyView.ABSTRACT Macroinvertebrate‐based flow indices have potential application to guiding environmental flow allocations and monitoring their effectiveness, but their sensitivity to such flows has seldom been tested. We examined the response of the Australian Macroinvertebrate Flow Index (AMFI), calculated from family‐level data, to three stages of ...

Will the Three Gorges Dam affect the underwater light climate of Vallisneria spiralis L. and food habitat of Siberian crane in Poyang Lake? [PDF]
, 2009 Almost 95% of the entire population of the Siberian crane (Grus leucogeranus) winter in Poyang Lake, China, where they forage on the tubers of the submerged aquatic macrophyte Vallisneria spiralis.

THE PERMISSIBLE INPUT OF BIOGENIC ELEMENTS TO WATER BODIES WITH SLOWED AND MODERATE WATER EXCHANGE
Водное хозяйство России: проблемы, технологии, управление, 2020 The article presents the outputs of researches on determination of permissible input of biogenic matter to water bodies with different types of moderate and slowed water exchange: that is phytoplankton, phytoplankton/macrophyte, and macrophyte types. We

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Fish and macroinvertebrates in lowland drainage canals with and without grass carp [PDF]
, 2006 Diploid grass carp (Ctenopharyngodon idella L.) were introduced to a lowland Waikato drainage canal at an initial density of 40-80 kg ha -1(83-167 fish ha -1) to control aquatic macrophytes and improve water flow.

AMEG: the new SETAC advisory group on aquatic macrophyte ecotoxicology [PDF]
, 2010 Introduction and background Primary producers play critical structural and functional roles in aquatic ecosystems; therefore, it is imperative that the potential risks of toxicants to aquatic plants are adequately assessed in the risk assessment of ...
