Journal ArticleDOI
The evolution of parental cooperation in birds
TL;DR: It is shown that parents cooperate more when sexual selection is not intense and the adult sex ratio of males to females is not strongly skewed, however, the degree of parental cooperation is unrelated to harshness and predictability of the ambient environment during the breeding season, suggesting that several types of parental care may coexist in a given set of ambient environment.
Journal ArticleDOI
Pollination mode predicts phenological response to climate change in terrestrial orchids: a case study from central Europe
V Attila Molnár,Jácint Tökölyi,Zsolt Végvári,Gábor Sramkó,Gábor Sramkó,József Sulyok,Zoltán Barta +6 more
TL;DR: It is demonstrated that the majority of Hungarian orchids have shifted their yearly mean flowering to earlier dates during the past 50 years, and certain life-history traits, but not phylogenetic relatedness, were found to be important in predicting climatic responsiveness in European terrestrial orchises.
Journal ArticleDOI
Variation in Haematological Indices and Immune Function During the Annual Cycle in the Great Tit Parus major
Péter L. Pap,Péter L. Pap,Csongor I. Vágási,Csongor I. Vágási,Jácint Tökölyi,Gábor Á. Czirják,Zoltán Barta +6 more
TL;DR: When juveniles became independent of their parents, the immunoglobulin concentration increased, whereas other immune measures did not show a significant change, which indicates a rapid increase of at least one component of the immune system after the young fledge.
Journal ArticleDOI
Higher seed number compensates for lower fruit set in deceptive orchids
Judit Sonkoly,Anna E. Vojtkó,Jácint Tökölyi,Péter Török,Gábor Sramkó,Gábor Sramkó,Zoltán Illyés,V Attila Molnár +7 more
TL;DR: The results indicate that deceptive orchids can compensate for their lower fruit-set by having more (but not larger) seeds in a fruit than rewarding species, and highlight possible ways in which plants can increase their reproductive success in face of pollinator limitation.
Journal ArticleDOI
Frequency and consequences of feather holes in Barn Swallows Hirundo rustica
TL;DR: It is suggested that the negative effect of feather holes on the fitness of the birds is mainly apparent during periods of intensive locomotor activity, such as migration, and that the tail is a condition-dependent secondary sexual characteristic.
