Food resource uncertainty shapes the fitness consequences of early spring onset in capital and income breeding migratory birds
Ejsmond, Anna; Ejsmond, Maciej Jan (Journal article; Peer reviewed, 2022)Due to climate change, the timing of spring arrival and nesting onset in many migratory bird species have advanced. Earlier spring onsets prolong the available breeding period but can also deteriorate local conditions, ... -
Nesting synchrony and clutch size in migratory birds: Capital versus income breeding determines responses to variable spring onset
Ejsmond, Anna; Forchhammer, Mads; Varpe, Øystein; Jónsson, Jón Einar; Jørgensen, Christian (Journal article; Peer reviewed, 2021)Synchronous reproduction of birds has often been explained by benefits from nesting together, but this concept fails to explain observed intraspecific variation and climate-mediated changes of breeding synchrony. Here, we ... -
Probing of mortality rate by staying alive: The growth-reproduction trade-off in a spatially heterogeneous environment
Ejsmond, Anna; Kozłowski, Jan; Ejsmond, Maciej Jan (Peer reviewed; Journal article, 2019)1. In many annual plants, mollusks, crustaceans and ectothermic vertebrates, growth accompanies reproduction. The growth curves of these organisms often exhibit a complex shape, with episodic cessations or accelerations ... -
Temporal constraints on reproduction and growth in a seasonal environment
Ejsmond, Anna (Doctoral thesis, 2021-06-16)The variety of life forms is one of the most striking phenomena that have stimulated research in evolutionary biology and ecology over recent decades. The crucial role in defining the most characteristic features of living ...
