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

, 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.

Seasonal changes in microbial dissolved organic sulfur transformations in coastal waters [PDF]

, 2020
The marine trace gas dimethylsulfide (DMS) is the single most important biogenic source of atmospheric sulfur, accounting for up to 80% of global biogenic sulfur emissions.

Photoreception in Phytoplankton [PDF]

Integrative and Comparative Biology, 2016
In many species of phytoplankton, simple photoreceptors monitor ambient lighting. Photoreceptors provide a number of selective advantages including the ability to assess the time of day for circadian rhythms, seasonal changes, and the detection of excessive light intensities and harmful UV light.

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Iron biogeochemistry across marine systems progress from the past decade [PDF]

, 2010
Based on an international workshop (Gothenburg, 14–16 May 2008), this review article aims to combine interdisciplinary knowledge from coastal and open ocean research on iron biogeochemistry. The major scientific findings of the past decade are structured

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Hydrodynamics drives shifts in phytoplankton community composition and carbon-to-chlorophyll a ratio in the northern South China Sea

Frontiers in Marine Science, 2023
Phytoplankton play significant roles in the carbon cycle in oceans. Phytoplankton biomass and community composition are often mediated by ocean hydrodynamics.

WISER deliverable D3.1-4: guidance document on sampling, analysis and counting standards for phytoplankton in lakes [PDF]

, 2012
Sampling, analysis and counting of phytoplankton has been undertaken in European lakes for more than 100 years (Apstein 1892, Lauterborn 1896, Lemmermann 1903, Woloszynska 1912, Nygaard 1949).
