Big ears with big veins are great for thermoregulation on a 37°C day on the Carrizo Plains.
Code, data, and exploration on GitHub.
Do native species density trials at two scale – micro and mesoscale using pots and large plastic buckets. Mix of potting soil and sand best – 50:50.
Consider intra and interspecific competition series – with replacement, i.e. keep net densities per pot consistent. Finally, perhaps consider competition with an exotic such as red brome.
then a*b, a*c, b*c
Or run each out in solo then against red brome.
We had a more ambitious set of goals this season.
- Habitat use frequency estimates. Tools: a. telemetry of blunt-nosed leopard lizard with a total at least 1200 relocations split between AM/PM with an estimate of shrub-open and behavior. b. cam traps at shrub-open on still mode.
- Behavior estimates. Tools: a. cam traps on video mode at a total of 100 hours recording time. b. direct observation (with recording too) by humans of lizards and grasshoppers at a total of 100hrs.
- Shrub-plant-animal interaction estimates. Tools: exclosures at two sites to exclude different taxa in shrub-open mesohabitats. a. cages. b. cams c. vacuums. d. sweeps.
- Temperature profile estimates. Tools: a. pulse of collars on lizards b. loggers at microhabitat scales.
- Census grasshoppers. Tools: stick, sweep, and vacuum. Also do direct observation to assess whether they are significant consumers.
1a. Mario and Steph. Goals 1,2,3,5.
1b. Malory and Nargol. Goals 1,2,5.
2. Emily and Kat. Goals 1 & 4.
Deploy one set of cam traps on still mode at a total no-shrub zone.
Get a solid handle on behavior by verts and inverts in the context of paired interactions with plants (at micro-scale) and shrubs at mesoscale.
Need an assay of insect diversity.
