Evaluation of factors affecting greater prairie‐chicken nest and brood survival
Wildlife Biology, EarlyView.Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...

Functional variation in butterfly egg pore traits: The potential role of climate
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

Breeding Dispersal of Baltic Dunlins Is Not an Adaptive Response to Unpredictable Nest Flooding
Animal Conservation, EarlyView.Flood‐related nest losses of the Baltic dunlin (Calidris alpina schinzii) have drastically increased over the past two decades. Using 20 years of reproductive data from 184 individuals, we found that between‐year and within‐site dispersal tended to increase following nest failure in males.
