It has a long history of providing the latest information on the application of reproductive technologies and includes a range of topics related to cow herd reproduction — such as nutritional interactions, management and male Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O. Wilson; K-selected Author: Created by Liffy98. We use cookies to ensure that we give you the best experience on our website. One way scientists have grouped reproductive strategies is articulated in the theory of r/K-selection. Reviews focused on animal reproductive strategies already exist (e.g., Fox and Czesak, 2000 for arthropods; Godfray et al., 1991; Monaghan and Nager, 1997 for birds; Einum et al., 2004 for fishes; Bernardo, 1996; Roff, 2002 for animals in general).
