Krill and the unity of biology

This supplement features some of the printed papers from the Second International Symposium on Krill (Santa Cruz, Calif., August 1999). Krill have long been recognized as key prey species for fish, birds, and marine mammals and as a target for fisheries in both hemispheres. However, the study of krill can contribute in many other ar- eas of biology. Krill are an excellent model system for studies of growth and maturity, for connections between theory, experiment, and observation, and for tests of evolutionary theory in the field. Krill are also ideal model organisms for studying the interaction between environmental and organismal variability. Because they are widely distributed but only moderately speciose, the study of krill can also shed light on the relationship between abundance and range. The study of krill is an inherently interdisciplinary field, crossing boundaries and using a combination of oceanography, biochem - istry, physiology, evolution, and ecology to understand krill and their role in the ecosystem. Resume : Ce supplement contient les textes de certaines presentations faites au Second symposium international sur le krill (Second International Symposium on Krill) tenu a Santa Cruz, Calif., en aout 1999. Depuis longtemps, on sait que les especes du krill sont des proies essentielles pour les poissons, les oiseaux et les mammiferes marins et une res - source convoitee par les peches commerciales dans les deux hemispheres. L'etude du krill peut aussi faire progresser plusieurs disciplines biologiques. C'est un systeme ideal pour analyser la croissance et la maturite, pour evaluer les rapports entre la theorie, l'experimentation et l'observation, ainsi que pour elaborer en nature des tests relatifs a la theorie de l'evolution. Les organismes qui le composent sont aussi d'excellents modeles pour mettre en lumiere les in- teractions entre la variabilite de l'environnement et celle des organismes. Parce que le krill a une repartition geogra- phique etendue et une richesse en especes moyenne, il permet l'etude des relations entre l'abondance et l'aire de distribution. Il s'agit essentiellement d'un domaine de recherche interdisciplinaire qui, a l'aide de l'oceanographie, de la biochimie, de la physiologie, de la biologie evolutive et de l'ecologie, cherche a comprendre la nature du krill et son role dans l'ecosysteme.
