Estimating food resource availability in arid environments with Sentinel 2 satellite imagery.

Background: In arid environments, plant primary productivity is generally low and highly variable both spatially and temporally. Resources are not evenly distributed in space and time (e.g.

Early-life social environment predicts social network position in wild zebra finches.

Early-life experience can fundamentally shape individual life-history trajectories. Previous research has suggested that exposure to stress during development causes differences in social behaviour later in life. In captivity, juvenile zebra finches exposed to elevated corticosterone levels were less socially choosy and more central in their social networks when compared to untreated siblings.

Six playback experimental designs fail to demonstrate acoustic preferences in common waxbills (Estrildidae: Estrilda astrild).

Playback experiments in controlled laboratory settings have been instrumental in studies of animal communication and signal evolution. Nonetheless, applying common methods to wild or non-model species can be challenging. We tested male and female common waxbills (Estrilda astrild) for behavioural preferences of conspecific vs.
