Threats and Shifts in Microbial Communities of Salars Associated With Direct Lithium Extraction and Brine Reinjection. [PDF]

Glob Chall
Lithium for rechargeable batteries is increasingly extracted from brines in high‐Andean salars. Direct Lithium Extraction (DLE) technologies are promoted as sustainable alternatives to conventional evaporation ponds. This work explores how brine modification and reinjection may affect microbial communities and ecosystem functioning, highlighting the ...

Bluetongue Virus Serotype 3 Follow-Up of the 2024 Outbreak in Two Belgian Zoos. [PDF]

Transbound Emerg Dis
In summer 2024, Western Europe experienced extensive outbreaks of bluetongue virus Serotype 3 (BTV‐3), a Culicoides‐borne orbivirus. Clinical disease was first detected in August 2024 in one of two Belgian zoos, predominantly affecting European bison (Bison bonasus) and American bison (Bison bison).

Dental Microwear Evidence of Holocene Dietary Variability in the Argentinian Pampas and Paraná Delta. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives This study explores the subsistence strategies of Middle‐to‐Late Holocene human populations in the Argentinean Pampas and Paraná River Delta by analyzing dental microwear patterns. Materials and Methods We examined occlusal molar microwear textures of individuals from the Middle and Late Holocene recovered from 12 archaeological ...

Density but not climate affects the population growth rate of guanacos ( Lama guanicoe) (Artiodactyla, Camelidae). [PDF]

F1000Res, 2013
We analyzed the effects of population density and climatic variables on the rate of population growth in the guanaco ( Lama guanicoe ), a wild camelid species in South America. We used a time series of 36 years (1977-2012) of population sampling in Tierra del Fuego, Chile.

Determination of age and sex on dental pieces of Lama guanicoe: A methodological approach

, 2014
Archaeozoological studies in central Tierra del Fuego are limited by the possibilities of bone conservation. This region is characterized by the development of the sub-Antarctic forest, where survival of organic material is very low, due to factors such as the acidity produced by leaves decomposition, humidity, roots action, ground freezing, etc.

Fecal Material of Captive Wild Animals as Source of CAZymes With Application Potential. [PDF]

Chembiochem
With the goal to identify a novel resource of enzymes, we tested for the potential of fecal metagenomes of captive wild animals to provide CAZymes. Our data show that CAZymes profiles differed between animals with varying gut physiology and diet, and that metagenomes of captive wild animals can be considered source of diverse CAZymes including rare and

Sweating in the guanaco (Lama guanicoe)

Journal of Thermal Biology, 2001
Sweat glands are present all over the skin, where sweat production varies from 4.98 to 73.36gm(-2)h(-1) of skin. Ambient temperatures between 20 and 33 degrees C are the main stimuli for activation of sweat glands, generating a heat loss ranging from 11.9 to 37% of standing basal metabolic rate.
