Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Comparative functional morphological study of the tarsal joint mobility in artiodactyls and perissodactyls in light of astragalar morphological differences

Journal of Anatomy, EarlyView.
This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

Potent and Broad Neutralization of HIV-1 by a Llama Antibody Elicited by Immunization [PDF]

, 2012
Llamas (Lama glama) naturally produce heavy chain–only antibodies (Abs) in addition to conventional Abs. The variable regions (VHH) in these heavy chain–only Abs demonstrate comparable affinity and specificity for antigens to conventional immunoglobulins

Patterns and drivers of range filling of alien mammals in Europe

Oikos, Volume 2025, Issue 9, September 2025.
Biological invasions are major drivers of biodiversity change. Alien mammals are particularly concerning in Europe, where their expansion remains unabated, though the driving factors are still unclear. Well‐documented introductions and distributions in this continent provide a unique opportunity to understand how human activities influenced this ...
