RESUMO
To evaluate the potential impact of our research activities on guanacos (Lama guanicoe), we tested for effects of radiocollaring on juvenile (≤1 year of age) survival in Torres del Paine National Park, Chile during 1992-1996. The survival of collared (40.1%) and uncollared (38.2%) juveniles was not significantly different (G=0.08; P=0.77). Our results suggest that radiocollaring does not adversely affect the survival of juvenile guanacos. Although we observed no effect of radiocollaring, we still underline the importance of testing for effects of radiocollars in other wildlife investigations when feasible.
RESUMO
Adult male guanacos were immobilized by use of tiletamine/zolazepam. The effective dosage (mean +/- SD) was 5.0 +/- 1.1 mg/kg of body weight. Mean time from injection to immobilization was 7.3 minutes. Usually, immobilization was of sufficient duration (mean, 61 minutes) to allow guanacos to be weighed, measured, and to have ear tags inserted and blood samples collected. Adverse effects included twitching and rigidity of muscles, salivation, chewing movements, retching, vocalization, and stumbling during the recovery phase. All guanacos recovered without apparent complications.

Preliminary blood typing tests were made on New World camelids, guanacos, llamas, and two hybrids. Erythrocyte samples were tested against a battery of cattle blood typing reagents. Three different reagents were prepared from rabbit anti-erythrocyte sera. Transferrin variation and lectin polymorphism also were observed. No naturally occurring isoantibodies were found. Blood typing tests of New World camelids were shown to be feasible for studies of taxonomic relationships.
