Are animals randomly distributed in the air, or is there a structure to where and when we find them? In our new paper we outline factors that shape habitat use in the air, from abiotic structure to biotic interactions. A lot of fun discussions behind this one! πŸ¦…πŸ¦‹πŸ¦‡πŸŒ¬

High above us, the atmosphere is teeming with life. New research from @cnilsson.science at Lund University reveals how the atmosphere is an ecosystem, with complex ecological processes that affect how animals move between different altitude levels of the airspace.

Online now: Animal niches in the airspace
Animal niches in the airspace
For flying animals, including many birds, bats, and insects, the air is a crucial arena for a range of behaviors. Technological advances, such as year-round tracking of flight altitudes and expanded use of radar, increasingly show how flying animals use the aerial habitat. This enables us to answer questions about the environmental patterns and ecological processes that shape aerial niches, including energetics, biotic interactions, and risk due to growing anthropogenic conflicts. In this review, we identify environmental conditions and biological interactions influencing where animals occur in the airspace throughout their life cycles. We outline an ecological framework to advance understanding of how different properties of the airspace shape fundamental aerial habitat niches and how biotic interactions influence the realized niches.

Migratory birds aren’t equally efficient at all speeds. A new Lund University study shows thrush nightingales fly most efficiently at 7–8 m/s – the speed they actually use on migration.
