Brown trout Salmo trutta is endemic to Europe, western Asia and north‐western Africa; it is a
prominent member of freshwater and coastal marine fish faunas. The species shows two …

Understanding and predicting how adaptation will contribute to species' resilience to climate
change will be paramount to successfully managing biodiversity for conservation …

Metapopulation is the ecological term for assemblages of plant and animal species within
larger areas of space, with long-term survival of the species depending on a shifting balance …

Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

▪ Abstract We describe the impact of recent life-history plasticity theory on insect studies,
particularly on the interface between genetics and plasticity. We focus on the three …

This contribution describes and identifies the most common reproductive strategies of a
large number of commercially important fish species of the North Atlantic with regard to …

The impetus for this book arose out of my previous book, The Evolution of Life Histories
(Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …

The great diversity of life-history patterns in the salmonids has stimulated many theoretical
studies. However, virtually all studies are based on ultimate considerations, in which …

Extensive individual variation in spatial behaviour is a common feature among species that
exhibit migratory life cycles. Nowhere is this more evident than in salmonid fishes; individual …
