Seasonality in Frequency of Marine Access to an Intermittently Open Estuary: Implications for Recruitment Strategies

Kim N. I. Bell, +3 more
- 01 Mar 2001 - 
TL;DR: In this paper, the seasonal pattern in access between the surf zone and an estuary, and the implications for recruitment success and process in fish that spawn at sea but spend their juvenile phase in estuaries, were examined.

Growth Estimates from Tagged White Sturgeon Suggest That Ages from Fin Rays Underestimate True Age in the Kootenai River, USA and Canada

Vaughn L. Paragamian, +1 more
- 01 Sep 2003 - 
TL;DR: Growth estimates from tagged white sturgeon in the Kootenai River indicated that age estimates from fin rays were underestimates of the true ages, and apparent aging bias will result in substantial changes in population parameters estimated from age, including growth, mortality, longevity, and year-cl...

Natural history and development of the introduced signal crayfish, Pacifastacus leniusculus, in a small, isolated Finnish lake, from 1968 to 1993

Jorma Kirjavainen, +1 more
- 01 Nov 1999 - 
TL;DR: Two Branchiobdellidae (Annelida, oligochaeta) epibiont species new to Finland were imported from North America with P. leniusculus and the continuous occurrence of these commensals in the signal crayfish population indicates that they have adapted to Finnish conditions.

Cycles of abundance among Fraser River sockeye salmon (Oncorhynchus nerka)

W E Ricker
- 01 Apr 1997 - 
TL;DR: In some but not all populations of sockeye salmon that mature mainly at age 4, there has been a persistently dominant line, a ``subdominant'' line about 10-25% as large as the dominant line.

Effect of size-selective predation by muskrats (Ondatra zebithicus) on a population of unionid clams (Anodonta grandis simpsoniana)

J. M. Hanson, +2 more
- 01 Feb 1989 - 
TL;DR: In this paper, the effect of size-selective predation by muskrats on the population size, sizestructure, and growth of clams was evaluated in a small lake in central Alberta.
