The biological carbon pump is the process that transports carbon vertically out of the mixed layer in the ocean. Besides the sinking flux of organic particles, active flux due to the daily vertical migration of zooplankton and micronekton promotes a significant carbon transport not fully accounted for or understood in the world’s oceans. The divers...

Larval fish composition and abundance were analyzed during February-March (winter) and November-December (autumn) of 2005 to investigate which environmental conditions and mesoscale oceanographic processes affect the distribution of larval fish assemblages in the Gulf of California, and if these variables and processes are useful to delimit specifi...
Chapter
Representatives of almost every phylum of protists have evolved symbiotic associations with crustaceans. The crustaceans are protected by their exoskeletons from external attacks by most protists; even a thin layer of exoskeleton, including on the gills, protects euphausiids against many parasites and pathogens. Euphausiids interact with protists w...
Chapter
Metazoan parasites have evolved complex life cycle strategies for finding hosts, obtaining energy and reproducing through monoxenous (interaction with only one kind of host during their life cycles) or heteroxenous (interacting with more than one kind of host) life cycles. Parasitic Crustacea are commonly monoxenous. Digenea, Cestoda, Nematoda and...
Chapter
We review all the available, worldwide reports of epibionts and parasites of species of the Order Euphausiacea published between 1885 and 2015 (126 publications, 346 records). We add our own observations carried out on euphausiids from waters off Oregon (USA), Tasmania (Australia), Concepción (Chile), and Mexico. This information provides us a rela...
Chapter
Here we discuss several examples of unidentified parasites (including some with unclear taxonomic positions), diseases of euphausiids reported in literature, and some of the authors’ previously unpublished observations. The taxonomic relationships and phylogeny of many euphausiid symbionts are currently unsatisfactory. Diseases of krill have rarely...
Chapter
Fungi associated with crustaceans include harmless commensals, opportunistic pathogens (usually saprophytic), and species that appear to be fully adapted as parasites. A majority of yeasts in the ocean are probably saprophytes, depending for their growth on the organics available after the death of various marine organisms. Fungi sometimes cause ep...
Chapter
We know essentially nothing about the function of bacteria as mutualistic, commensal symbionts or disease producers in natural populations of crustaceans, particularly euphausiids. Chitinoclastic bacteria associated with euphausiids were discovered in 1963. Since the 1970s, bacteria associated with temperate and polar euphausiids have been studied,...
Chapter
Viruses are small particles, usually about 20–200 nm in diameter, consisting of genetic material (DNA or RNA, single- or double-stranded) surrounded by a protein coat (some also have lipids). They have no intrinsic metabolism and function only as parasites using the cellular machinery of a host organism. In theory, all cellular organisms are suscep...
