Roads have no effect on guanaco habitat selection at a Patagonian site with limited poaching

Global Ecology and Conservation, 2018
Roads affect flora and fauna across the world. Large mammals are particularly vulnerable to road effects because their large home ranges lead to a higher probability of contact with road networks.

Range Management Affects Native Ungulate Populations in Penísula Valdés, a World Natural Heritage [PDF]

, 2013
Sheep rearing is the main productive activity in Patagonian rangelands, where guanacos are the only native ungulate. Ranchers perceive a decrease in range carrying capacity as guanaco numbers increase, therefore guanaco conservation within private ...

Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

Sedimentology, EarlyView.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

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 ...

Sexual and Age‐Related Morphological Variations in the Pelvis of Lama guanicoe guanicoe (Artiodactyla: Camelidae)

International Journal of Zoology, Volume 2026, Issue 1, 2026.
This study explores the scope of sexual and age‐related discrimination in the hemipelvises of Lama guanicoe guanicoe (Müller 1776), a species that lacks postcranial secondary sexual characteristics. Using two‐dimensional geometric morphometric techniques, changes in shape and size of the coxae bones from 50 individuals of both sexes and varying ...

Structural and Functional Properties of Araucaria araucana and Araucaria angustifolia Seed Proteins as a Plant‐Based Food Source

Sustainable Food Proteins, Volume 3, Issue 4, December 2025.
Morphologically, A. angustifolia seeds were significantly larger, while A. araucana exhibited more regular, triangular shapes. Proximate composition revealed a carbohydrate‐rich profile in both species, with a significantly higher lipid content in A. araucana. Amino acid analysis showed similar profiles, with high levels of aspartic and glutamic acids.
