Selection on larval and adult body size in a marine fish: potential evolutionary responses and effects on population dynamics

Creator:

Johnson, Darren W.

Abstract:

Many species have complex life cycles in which a dispersive larval stage is followed by a relatively sedentary adult stage. For such species, reproductive output is often high and large variation in survivorship throughout early life-history phases (eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...

AN ABSTRACT OF THE DISSERTATION OF Darren W. Johnson for the degree of Doctor of Philosophy in
Distribution and abundance of juvenile demersal fishes in relation to summer hypoxia and other environmental variables in coastal Oregon, USA

Creator:

Sobocinski, Kathryn L., Ciannelli, Lorenzo, Wakefield, W. Waldo, Yergey, Matthew E., and Johnson-Colegrove, Angela

Abstract:

The juvenile demersal fish assemblage along the Pacific Northwest coast has received little attention relative to adult life history stages since pioneering work in the 1970s. Increasing severity of hypoxia along the Oregon coast in recent years has prompted investigations into the response of biota in this region. We used...
