Population structure attributable to reproductive time: isolation by time and adaptation by time

AP Hendry, T Day - Molecular ecology, 2005 - Wiley Online Library
Many populations are composed of a mixture of individuals that reproduce at different times,
and these times are often heritable. Under these conditions, gene flow should be limited …

Fishery‐induced demographic changes in the timing of spawning: consequences for reproductive success

PJ Wright, EA Trippel - Fish and Fisheries, 2009 - Wiley Online Library
Demography can have a significant effect on reproductive timing and the magnitude of such
an effect can be comparable to environmentally induced variability. This effect arises …

Role of the estuary in the recovery of Columbia River basin salmon and steelhead: an evaluation of the effects of selected factors on salmonid population viability

KL Fresh, E Casillas, LL Johnson, DL Bottom - 2005 - repository.library.noaa.gov
The primary purpose of this technical memorandum is to evaluate the potential of selected
factors associated with the Columbia River estuary to improve viability of listed anadromous …

Adaptive variation in senescence: reproductive lifespan in a wild salmon population

AP Hendry, YE Morbey, OK Berg… - Proceedings of the …, 2004 - royalsocietypublishing.org
The antagonistic pleiotropy theory of senescence postulates genes or traits that have
opposite effects on early–life and late–life performances. Because selection is generally …

Individual-based analyses reveal high repeatability in timing and location of reproduction in lake sturgeon (Acipenser fulvescens)

PS Forsythe, JA Crossman, NM Bello… - Canadian Journal of …, 2012 - cdnsciencepub.com
Few studies have quantified the repeatability of reproductive decisions by individuals or
assessed their relationship with environmental variables over multiple seasons for long …

Founding events influence genetic population structure of sockeye salmon (Oncorhynchus nerka) in Lake Clark, Alaska

KM Ramstad, CA Woody, GK Sage… - Molecular …, 2004 - Wiley Online Library
Bottlenecks can have lasting effects on genetic population structure that obscure patterns of
contemporary gene flow and drift. Sockeye salmon are vulnerable to bottleneck effects …

Fine‐scale temporal adaptation within a salmonid population: mechanism and consequences

AJ Gharrett, J Joyce, WW Smoker - Molecular Ecology, 2013 - Wiley Online Library
We demonstrate a clear example of local adaptation of seasonal timing of spawning and
embryo development. The consequence is a population of pink salmon that is segmented …

Isolation by time and habitat and coexistence of distinct host races of the common cuckoo

AP Møller, A Antonov, BG Stokke… - Journal of …, 2011 - academic.oup.com
Isolation by time occurs when different populations of a single species reproduce at different
times and thereby reduce the probability of interbreeding, potentially causing divergent …

Bimodal run distribution in a northern population of sockeye salmon (Oncorhynchus nerka): life history and genetic analysis on a temporal scale

EK Fillatre, P Etherton, DD Heath - Molecular Ecology, 2003 - Wiley Online Library
Life history variation and genetic differentiation were analysed in sockeye salmon in Klukshu
River, Yukon Canada over 7 years (1994–2000). Sockeye salmon return to the Klukshu …
