Initial incorporation of phytoplankton into young ice in Saroma Ko lagoon, Hokkaido, Japan [PDF]

open access: yes, 2000
P(論文)The initial incorporation of phytoplankton into young ice was examined on February 25-28,1998 in Saroma Ko lagoon, Hokkaido, Japan to test our hypothesis that some physical selection would occur to establish the ice algal assemblages during the ...

The influence of physico-chemical parameters on phytoplankton distribution in a head water stream of Garhwal Himalayas: A case study

open access: yesEgyptian Journal of Aquatic Research, 2016
Physico-chemical parameters play a major role in determining the density, diversity and occurrence of phytoplankton in a headwater stream. The present study was conducted to assess the relationship between physico-chemical parameters and phytoplankton ...

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

PRIMARY PRODUCTION OF PHYTOPLANKTON AND MACROPHYTES IN AN EUTROPHIC LAGOON, LAKE KYUNGPO, KOREA [PDF]

open access: yes, 1991
Primary production of phytoplankton and macrophytes are measured in a eutrophic lagoon, Lake Kyungpo, where 86% of the lake is inhabited by macrophytes. Phytoplankton standing crop was high, 40-130 mgChl/m³, but productivity per unit area was suppressed ...

Phytoplankton Community Composition Along Environmental Gradients in the North Pacific Ocean [PDF]

open access: yes, 2022
Prochlorococcus is a cyanobacterium smaller than 1 μm that accounts for much of the primary production in nutrient-poor areas such as the North Pacific Subtropical Gyre (NPSG).

Short-term responses of littoral phytoplankton in a large shallow subtropical lake [PDF]

open access: yesAnais da Academia Brasileira de Ciências
The littoral zone is an essential compartment for lake biota because of its high productivity and diversity. Moreover, phytoplankton is expected to have non-equilibrium dynamics on it.

Intraspecific variability in feather moult extent declines under both low and high constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variability (ITV) is a fundamental feature of biological populations and the raw material upon which natural selection acts, yet its drivers remain poorly understood.

Spatial and temporal trends of phytoplankton and physiochemical variables in a hypertrophic, monomictic lake [PDF]

open access: yes, 2011
Spatial and temporal variations in the physical, chemical and biological composition of Lake Ōkaro were measured over 16 months. Lake Ōkaro is a small (0.32 km2) hypertrophic, monomictic lake located in the Central Volcanic Zone of the North Island, New ...

Distribution of phytoplankton functional types in high-nitrate low-chlorophyll waters in a new diagnostic ecological indicator model [PDF]

open access: yes, 2013
Modeling and monitoring plankton functional types (PFTs) is challenged by insufficient amount of field measurements to ground-truth both plankton models and bio-optical algorithms.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

open access: yesJournal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.
