In addition to the striking beauty inherent in their complex nature, fractals have become a
fundamental ingredient of nonlinear dynamics and chaos theory since they were defined in …

Explanations for the patchy distribution of marine phytoplankton are critically reviewed with
the focus on the role played by lateral advection and mixing. Generating mechanisms for …

Chemical and biological processes often take place in fluid flows. Many of them, like
environmental or microfluidical ones, generate filamentary patterns which have a fractal …

Coexistence of competitive species is severely limited by the availability of resources and
the characteristics of the environment. In particular, the so–called–competitive exclusion …

The horizontal stirring properties of the flow in a region of the East Australian Current are
calculated. A surface velocity field derived from remotely sensed data, using the maximum …

Many chemical and biological processes take place in fluid environments in constant
motion? chemical reactions in the atmosphere, biological population dynamics in the ocean …

Temporal segregation is known to be an important mechanism of coexistence in many
foraging guilds but has not been examined in avian scavengers. Given that carrion …

Experiments are presented on pattern formation in the Belousov-Zhabotinsky (BZ) reaction
in a blinking vortex flow. Mixing in this flow is chaotic, with nearby tracers separating …

About 60 years ago, the critical depth hypothesis was proposed to describe the occurrence
of spring phytoplankton blooms and emphasized the role of stratification for the timing of …

1. In this introduction, I try to follow some developments in plankton ecology, how they have
led to current research topics, and how the contributions in this issue of Freshwater Biology …
