The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Temperature orchestrates phytoplankton community and environment in mountain stream for enhancing resource use efficiency

open access: yesFrontiers in Marine Science
Warming is a key factor influencing the function of the structure and function of phytoplankton communities. However, the impacts of temperature on phytoplankton resource use efficiency (RUE) in mountain rivers remain poorly understood.

Net phytoplankton and zooplankton in the New York Bight, January 1976 to February 1978, with comments on the effects of wind, Gulf Stream eddies, and slope water intrusions [PDF]

open access: yes, 1984
Results are given of monthly net phytoplankton and zooplankton sampling from a 10 m depth in shelf, slope, and Gulf Stream eddy water along a transect running southeastward from Ambrose Light, New York, in 1976, 1977, and early 1978.

Insights Into the Distribution of Two Bloom‐Forming Dinoflagellates of Phytosanitary Concern Using Regional and Global Temperature Data

open access: yesInternational Review of Hydrobiology, EarlyView.
ABSTRACT Large bloom‐forming dinoflagellates can alter aquatic biodiversity and impact human use, posing conservation challenges. We used the maximum entropy (MaxEnt) model to predict the potential distribution of two Ceratium congeners, C. hirundinella and C.

Phytoplankton Communities in Rudrasagar Lake, Tripura (North-East India) – A Ramsar Site

open access: yesInternational Journal of Bio-Resource and Stress Management, 2020
Phytoplankton is the integral link of food webs in the transfer of energy to higher aquatic communities that can also act as biological indicators for evaluation of trophic status of an aquatic ecosystem. The present study was carried out during October

STRUKTUR KOMUNITAS FITOPLANKTON DI DANAU TOBA, SUMATERA UTARA

open access: yesJurnal Ilmu Pertanian Indonesia, 2016
Lake Toba is the largest lake in Indonesia, located in the Province of North Sumatra. Lake Toba is used to aquaculture, agricultural, tourism, and residential areas. These activities will produce organic and anorganic matter that can affect water quality

Synthetizing hydrodynamic turbulence from noise: formalism and applications to plankton dynamics [PDF]

open access: yes, 2003
We present an analytical scheme, easily implemented numerically, to generate synthetic Gaussian 2D turbulent flows by using linear stochastic partial differential equations, where the noise term acts as a random force of well-prescribed statistics.

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, EarlyView.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

Phytoplankton periodicity: its motivation, mechanisms and manipulation [PDF]

open access: yes, 1982
This review summarizes some recent work to find a generalized explanation of phytoplankton periodicity in lakes. Much of the observational and experimental evidence is drawn from work centred on the large enclosures (Lund Tubes) installed in Blelham Tarn,
