Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay

Journal of Phycology, EarlyView.
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

Community assembly mechanism of phytoplankton in drinking water sources of tropical island, China

Frontiers in Ecology and Evolution
IntroductionPhytoplankton, as primary producers in aquatic ecosystems, serves as indicators of the health of water environments. In tropical island regions facing the combined pressures of human activities and climate change, understanding the mechanism ...

Effects of light and nutrient gradients on the taxonomic composition, size structure and physiological status of the phytoplankton community within a temperate eutrophic estuary

, 2006
Estuaries are important ecosystems which are affected by a large range of environmental factors. It is important to measure, characterise and monitor the ecological status of estuaries, and this is the contribution of this thesis for phytoplankton ...

Social roles and resource competition mediate intraspecific interactions of Chilean Flamingo (Phoenicopterus chilensis) in southern Brazil

Journal of Zoology, EarlyView.
In social birds such as flamingos, intraspecific interactions are frequent and play a key role in flock cohesion, communication, and the establishment of social networks. Understanding the patterns and drivers of these interactions can provide valuable ecological insights and inform management, husbandry, and conservation practices.

Phytoplankton adaptation to marine ecosystems: insights into photophysiological functional diversity

, 2011
The aim of this study was to investigate the diversity of the photoprotective responses activated by phytoplankton at short temporal scales, i.e. the non-photochemical quenching of Chl a fluorescence (NPQ) associated with the xanthophyll cycle (XC ...

Abundance, size structure and community composition of phytoplankton in the Southern Ocean in the austral summer 1999/2000

, 2002
P(論文)The abundance, size structure and community composition of phytoplankton in the Southern Ocean were studied, using flow cytometry, microscopy and pigment profiles on two transects one latitudinal (N) and one longitudinal (W) during December 1999 and

Phytoplankton ecology in the early years of a boreal oil sands end pit lake

Environmental Microbiome
Background Base Mine Lake (BML) is the first full-scale end pit lake for the oil sands mining industry in Canada. BML sequesters oil sands tailings under a freshwater cap and is intended to develop into a functional ecosystem that can be integrated into ...

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

New Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...
