Maternal transfer of androgens in eggs is affected by food supplementation but not by predation risk

Autor: Toni Laaksonen, Robert L. Thomson, Erkki Korpimäki, Esa Lehikoinen, Erich Möstl, Chiara Morosinotto, Suvi Ruuskanen

Publikováno v: Journal of Avian Biology, 47(5), 629-641. John Wiley and Sons Ltd

Mothers may affect the future success of their offspring by varying allocation to eggs and embryos. Allocation may be adaptive based on the environmental conditions perceived during early breeding. We investigated the effects of food supplementation

The Roots of Finnish Avian Ecology: From Topographic Studies to Quantitative Bird Censuses

Autor: Timo Vuorisalo, Esa Lehikoinen, Risto Lemmetyinen

Publikováno v: Annales Zoologici Fennici. 52:313-324

Ornithological research classified as topographic shared certain characteristics, including location type descriptions, full species lists of breeding birds for each location type, and usually at least a relative estimate of each species' abundance.

Ecology and Evolution, 5(6), 1205-1213. John Wiley and Sons Ltd

For migratory birds, the earlier arrival of males to breeding grounds is often expected to have fitness benefits. However, the selection differential on male arrival time has rarely been decomposed into the direct effect of male arrival and potential

Corticosterone secretion patterns prior to spring and autumn migration differ in free-living barn swallows (Hirundo rustica L.)

Autor: Mikko Nikinmaa, Esa Lehikoinen, Petri Suorsa, Tapio Eeva, Dalene Vosloo, Sari Raja-aho, Minna Vainio

Publikováno v: Oecologia. 173:689-697

Recent studies of long-distance migratory birds show that behavioural and physiological changes associated with predictable or unpredictable challenges during the annual cycle are distinctively regulated by hormones. Corticosterone is the primary ene

Publikováno v: Ibis. 155:357-366

Population consequences of parasites in wild birds are rarely documented. One exception is the decline of British finch populations due to an epidemic caused by the protozoan parasite Trichomonas gallinae. Finch trichomonosis has recently spread from

Long-lasting effects of yolk androgens on phenotype in the pied flycatcher (Ficedula hypoleuca)

Autor: Toni Laaksonen, Wolfgang Waser, Mikko Nikinmaa, Esa Lehikoinen, Heli Siitari, Suvi Ruuskanen

Publikováno v: Behavioral Ecology and Sociobiology. 67:361-372

The hormonal environment during early development, such as maternally derived androgens in bird eggs, shapes the development of the offspring in ways that may have important long-term consequences for phenotype and behavior and, ultimately, fitness.
