Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

open access: yesSustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing

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

open access: yesVeterinary 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 ...

Plant clonal morphologies and spatial patterns as self-organized responses to resource-limited environments

open access: yes, 2014
We propose here to interpret and model peculiar plant morphologies (cushions, tussocks) observed in the Andean altiplano as localized structures. Such structures resulting in a patchy, aperiodic aspect of the vegetation cover are hypothesized to self ...

Evaluation of a rapid method for measuring lactate in the venous blood of ruminants

open access: yesVeterinary Record, EarlyView.
Abstract Background In cattle and small ruminants, blood lactate can predict recovery and survival in various diseases. Increased lactate concentration is associated with an unfavourable‐to‐poor prognosis. Different mobile rapid lactate measurement devices have been explored in different animal species.
