Evaluation of a non‐radioactive rapid test for determination of serum progesterone in South American camelids

Veterinary Record, EarlyView.
Abstract Background Determination of the serum progesterone (P4) concentration is of high importance in reproductive medicine and may be applied for diagnosing pregnancy in South American camelids. P4 measurements in alpacas and llamas are usually performed using immunoassays, which are time consuming and require appropriate expertise of laboratory ...

Reproduction in female South American domestic camelids [PDF]

Bioscientifica Proceedings, 2019
Alpacas and llamas are induced ovulators. They show marked reproductive seasonality in the Andean region, but under Northern Hemisphere conditions of feeding and management, they are non-seasonal breeders. Puberty is attained when they reach 50% of adult body weight.

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.
