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.

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! 🦅🦋🦇🌬

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.

NEW PAPER: determinants of stopover duration in migratory blackbirds: lean birds extend stopovers, immune status has a weak effect. Weather conditions (cloud cover, tailwinds) are more influential.

➡️ https://vist.ly/3mtjme6

#ornithology #migration #ecoimmunology #birds
.
Fig. 1 from the article: Departure moments of blackbirds on Vlieland were associated with positive tailwinds, low cloud cover scores, and low scaled mass indices at arrival. In panel (a), horizontal lines represent the time each individual spent on the stopover location since the moment of first capture (open plotting symbols) until the moment of departure (vertical end line). In panel (b), cloud cover at sunrise or the moment of an individual's departure are plotted over date. Fig. 2 from the article: Minimal adequate model fits with (dotted blue line), and without (solid red line) a random intercept for the day of tagging, with corresponding 95% confidence intervals (shaded blue and red areas, respectively). Lines show the ratio between the risk of departure, relative to an individual with all other covariates set at the sample's mean, for (a) scaled mass index, (b) haptoglobin level (the residual concentration over pre-scan absorbance at 450 nm) Fig. 2 from the article: Minimal adequate model fits with (dotted blue line), and without (solid red line) a random intercept for the day of tagging, with corresponding 95% confidence intervals (shaded blue and red areas, respectively).

I think it is possible and in many cases they do continue, although a bit confused, just like in the comic! Especially for unexperienced birds of course, while older birds could be more used to switching to other cues when they encounter disturbances. Love the comic, such beautiful colors!
