Proximate control and adaptive potential of protandrous migration in birds [PDF]
, 2017 Migration determines where, when, and in which order males and females converge for reproduction. Protandry, the earlier arrival of males relative to females at the site of reproduction, is a widespread phenomenon found in many migratory organisms ...

Seasonal Photoperiods Alter Developmental Time and Mass of an Invasive Mosquito, Aedes albopictus (Diptera: Culicidae), Across Its North-South Range in the United States [PDF]
, 2012 The Asian tiger mosquito, Aedes albopictus (Skuse), is perhaps the most successful invasive mosquito species in contemporary history. In the United States, Ae.

New Phytologist, EarlyView.Summary Secondary contact between incipient species provides the opportunity to understand how trait divergence restricts gene flow. While mating system transitions are particularly common and involve a suite of phenotypic changes, the extent to which these changes influence gene flow during speciation is poorly understood.

Frontiers in Zoology, 2012 Sexual selection is a major force driving evolution and is intertwined with ecological factors. Differential allocation of limited resources has a central role in the cost of reproduction.

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Long‐distance migrants face numerous challenges during their migration, with the spring migration timing being particularly important, as early arrival at the breeding grounds often enhances breeding success. Both innate and environmental factors influence migration timing in birds, and the earlier arrival of males than females is common among ...

Protandry models and their application to salmon [PDF]
Behavioral Ecology, 2002 Mating systems characterized by restricted breeding seasons, male polygamy, and female monogamy are common among animals. In such systems (e.g., butterflies), the earlier emergence of males than females to breeding areas (protandry) is a typical phenological pattern. Protandry likely results from a timing strategy that maximizes mating opportunities by

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Shorebirds typically spend more time fueling and refueling during migration than they spend in actual flight, and consequently their stopover ecology has important implications for fitness and conservation. We examined spatial variation and long‐term changes in stopover duration of radio‐tagged western sandpipers Calidris mauri over three decades on ...

Pistil Development Delay Limits Seed Set in Protandrous Onion (Allium cepa L.)
AgronomyOnion (Allium cepa L.) plants produce umbellate inflorescences that bear dozens of hermaphrodite flowers. Outcrossing is encouraged by a strong protandrous dichogamy.

Protandry promotes male pollination success in a moth‐pollinated orchid [PDF]
Functional Ecology, 2007 SummaryTemporal separation of male and female phases in hermaphrodite flowers (dichogamy) is proposed to reduce self‐pollination, both within and among flowers. Darwin and later workers suggested that protandry (the most common form of dichogamy, in which the male phase precedes the female phase) should be most effective in reducing geitonogamous ...
