Life history theory (LHT) is an analytical framework [1] ... Biological tradeoffs also appear to characterize the life histories of viruses, including bacteriophages.
Evolutionary tradeoffs can be present in a form called life history tradeoffs, which can be defined as the decrease in fitness (essentially, lifetime reproductive success) caused by one life history trait as a result of the increase in fitness caused by a different life history trait. [5] Life history traits are traits closely linked to fitness ...
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
In 1847, Carl Bergmann published his observations that endothermic body size (i.e. mammals) increased with increasing latitude, commonly known as Bergmann's rule. [9] His rule postulated that selection favored within species individuals with larger body sizes in cooler temperatures because the total heat loss would be diminished through lower surface area to volume ratios.

Winemiller's early research on the life history of fish species resulted in the development of the triangular continuum, or E-P-O (Equilibrium-Periodic-Opportunistic) model. The model arose from an analysis of reproductive traits and demographic parameters using his own field-derived datasets and data compiled via review of hundreds of articles ...
Euteleostei, whose members are known as euteleosts, is a clade of bony fishes within Teleostei that evolved some 240 million years ago, although the oldest known fossil remains are only from the Early Cretaceous. [1]
Born and raised in San Diego and now living in San Francisco, Della Cava defies the stereotype of the laid-back, sun-chasing Californian. Impeccably dressed, well-groomed, and tall, she exudes a ...
Dorsal fin of a shark. A dorsal fin is a fin on the back of most marine and freshwater vertebrates.Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous.
