Effects of shelter addition on Akodon azarae and Calomys laucha (Rodentia, Muridae) in agroecosystems of Central Argentina during winter
We studied effects of shelter supplementation on population and individual parameters of two rodent species, Akodon azarae and Calomys laucha in pampean agroecosystems of Central Argentina during winter. The study was conducted using mark and recapture samplings in six cultivated fields with sunflow...
