Protandry and female size-fecundity variation in the tropical butterfly Brassolis sophorae

open access: yesOecologia, 1998
Protandry (the emergence of males before females) is currently explained either as a mating strategy to maximize number of matings in the males, or a way to minimize pre-reproductive mortality in females. Models of protandry have generally ignored variation in female quality (reproductive potential).

Protandry, sexual selection and climate change

Global Change Biology, 2004
AbstractProtandry refers to the earlier appearance of males before females at sites of reproduction. Sexual selection has been hypothesized to give rise to sex differences in benefits and costs of early arrival, thereby selecting for earlier appearance by the sex subject to more intense sexual selection.

Protandry, sexual size dimorphism, and adaptive growth

Journal of Theoretical Biology, 2013
Adaptive growth refers to the strategic adjustment of growth rate by individuals to maximize some component of fitness. The concept of adaptive growth proliferated in the 1990s, in part due to an influential theoretical paper by Peter Abrams and colleagues. In their 1996 paper, Abrams et al.

Sex-specific difference in migration schedule as a precursor of protandry in a long-distance migratory bird

open access: yesDie Naturwissenschaften, 2019
Protandry, the earlier arrival of males at the breeding grounds relative to females, is common in migratory birds. However, due to difficulties in following individual birds on migration, we still lack knowledge about the spatiotemporal origin of ...

Sex-related variation in migration phenology in relation to sexual dimorphism: a test of competing hypotheses for the evolution of protandry

open access: yesJournal of Evolutionary Biology, 2010
Timing of arrival/emergence to the breeding grounds is under contrasting natural and sexual selection pressures. Because of differences in sex roles and physiology, the balance between these pressures on either sex may differ, leading to earlier male ...

Protandry in Delia antiqua (Diptera: Anthomyiidae)

Annals of the Entomological Society of America, 1995
Sex differences in the duration of egg-larval and pupal stages, and in eclosion curves were examined under 3 different temperature regimes in the laboratory to assess the likelihood of protandry as an adaptive strategy for the onion maggot, Delia antiqua (Meigen).
