Spatio-temporal monitoring of lake fish spawning activity using environmental DNA metabarcoding
Peaks of Arctic charr relative read counts from eDNA metabarcoding were observed during the spawning season and at specific locations of both putative and known spawning sites.
Check out my recent #JFB Editor's Choice: Lump by name, but not by nature: 1000km migration of lumpfish (Cyclopterus lumpus) https://doi.org/10.1111/jfb.16074
Highlights work by Kennedy et al which shows #lumpfish are capable of frequent long distance #migration between #pelagic summer feeding areas and costal #spawning sites, with migrations up to 1,612 km recorded. It just goes to show that you can't judge a book by its cover!

a] with a systemd service on a headless device , it may be preferable to start it on boot and keep it running rather than only running during an interactive login session. Among other things, this helps prevent a *race condition* that may occur when socket activation fails to initialize audio devices in time for their first use, leading to one-time errors after reboots
b] til #spawning tmux is managed by systemd even if its a user service
when is a #systmd job or service or #linux user session supposed to linger is matter of how a service depends on the other *or not*
moreover some of these may have their own user accounts like rootless containers , with their own namespaces , which need be mapped to other services like #vpn
one can always check it with systemctl --user or linctl
so #podman has this runRoot directory: "/run/user/1000/containers" graphRoot directory
