Unrepeatable repeatabilities: a common mistake
C. M. Lessells,Peter T. Boag +1 more
TL;DR: The correct calculation of repeatability is outlined, a common mistake is pointed out, how the incorrectly calculated value relates to repeatable values is shown, and a method for checking published values and calculating approximate repeatability values from the F ratio is provided.
Climate change and population declines in a long-distance migratory bird
TL;DR: In a comparison of nine Dutch populations, it is found that populations have declined by about 90% over the past two decades in areas where the food for provisioning nestlings peaks early in the season and the birds are currently mistimed.
Warmer springs lead to mistimed reproduction in great tits (Parus major)
TL;DR: This work believes that this is the first documented case of an adaptive response being hampered because a changing abiotic factor affects the environment in which a reproductive decision is made differently from the environments in which selection occurs.
Do simple models lead to generality in ecology
Matthew R. Evans,Volker Grimm,Karin Johst,Tarja Knuuttila,Rogier De Langhe,C. M. Lessells,Martina Merz,Maureen A. O’Malley,Steve H. Orzack,Michael Weisberg,Darren J. Wilkinson,Olaf Wolkenhauer,Tim G. Benton +12 more
TL;DR: It is argued here that viewing simple models as the main way to achieve generality may be an obstacle to the progress of ecological research, and how complex models can be both desirable and general.
Sperm competition games: A general model for precopulatory male-male competition
TL;DR: A general model of sperm allocation is developed that allows us to examine the effect of all forms of precopulatory competition on sperm allocation patterns and predicts that sperm allocation decreases if either the “mate‐competition loading,”a, or the number of males competing for each mating, M, increases.
