Summer Rodent Update

September 21, 2009

We’ve had an active summer, but no thanks to the rodents. The numbers have remained low (along with the precipitation), dropping from 172 in May and June, 135 in July, to 94 in August. We found plenty of other things to entertain ourselves with, though.

Thanks to having an arachnologist with us in July, we saw many species of spiders, as well as many other interesting arthropod moments.



Despite the low numbers, we’re still catching some rarer species and unintended species:

We’ve encountered many other species, as well. Horned lizards, in particular, seem to be increasingly common on the site.

July was hot and dry.

In August we finally got some weather, complete with dust storms, rain, wind, and lightning.

July Rodent Census

August 28, 2008

The remanents of hurricane Dolly hit the site last month while the trapping was occurring, so our numbers were probably low because the weather was bad. However, we still caught 1 of the 4 tagged Dipodomys spectabilis that are currently residing on the site. We go back down very soon, so we should have a better feel for what the rodents are actually up to.
