Although typically portrayed as annoying to humans, such accumulations probably are …

Open ocean zooplankton often have been viewed as slowly evolving species that have
limited capacity to respond adaptively to changing ocean conditions. Hence, attention has …

The genus Pseudo-nitzschia includes several species capable of producing domoic acid,
the causative agent of Amnesic Shellfish Poisoning. Some of these species have been …

Body size is a central feature of any organism, reflecting its physiology, ecology and
evolutionary history. Marine microplankton are major contributors to the particulate inorganic …

Introduction Many marine planktonic crustaceans such as copepods have been considered
as widespread organisms. However, the growing evidence for cryptic and pseudo-cryptic …

The genus Pseudo-nitzschia includes a number of species responsible for blooms in coastal

An accurate identification of species and communities is a prerequisite for analysing and
recording biodiversity and community shifts. In the context of marine biodiversity …

Although theory dictates that limited gene flow between populations is a necessary
precursor to speciation under allopatric and parapatric models, it is currently unclear how …

Traditionally, many small-sized copepod species are considered to be widespread, bipolar
