The view on the ecology of marine plankton has changed significantly within the last
decade. In some respects the change is sufficiently dramatic to make some authors speak …

Ciliates are abundant and ubiquitous components of the marine plankton. Marine planktonic
ciliates include hundreds of species of loricate (shell-bearing) members of the suborder …

Arranging organisms into functional groups aids ecological research by grouping organisms
(irrespective of phylogenetic origin) that interact with environmental factors in similar ways …

Many protist plankton are mixotrophs, combining phototrophy and phagotrophy. Their role in
freshwater and marine ecology has emerged as a major developing feature of plankton …

The 'biological pump'mediates flux of carbon to the interior of the ocean by interctions
between the components of the vertically-structured pelagic ecosystem of the photic zone …

BACKGROUND Oceanographers began studying the ocean microbiome in earnest over
four decades ago, when it was recognized that microbes are responsible for nearly all of the …

This is a book about the natural history of oxygen-free environments and their microbial
inhabitants. Life originated in the pre-oxic world, and anoxic conditions still persist in many …

Mixotrophy is a common phenomenon among planktonic algae and protozoa. Mixotrophic
protists that combine phagotrophy and phototrophy are often abundant in the euphotic zone …

Acquisition of phototrophy is widely distributed in the eukaryotic tree of life and can involve
algal endosymbiosis or plastid retention from green or red origins. Species with acquired …
