Homo sapiens, industrialisation and the environmental mismatch hypothesis
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset

Early acclimatization to high altitude: Acid-base and fluid balance dynamics during the first 2 days at 3100 m. [PDF]
Abstract Immediate responses to hypoxia at high altitude are hyperventilation and successive respiratory alkalosis. Alkalosis, in turn, can affect cerebrospinal fluid pH and ventilatory control. The kidneys compensate metabolically for respiratory alkalosis.

This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Listening to the Atmosphere: Using Infrasound Observations to Infer Atmospheric Conditions
Abstract The stratosphere and mesosphere are important regions for the prediction of weather at the Earth's surface for medium‐ and long‐range forecasts. The availability of observations in these layers is lower than that of the troposphere, especially for the dynamics. While seeking new observational sources is important, there are existing infrasound

As Mexico faces rising temperatures and increasing events of extreme heat, improvements in the analysis and characterisation of these phenomena are necessary, as they offer new insights into the spatial variability of such trends and their underlying causes.

Evaluation of the yield stability of lentil genotypes by combining AMMI and BLUP techniques
Abstract This study evaluated the yield stability of 14 advanced lentil genotypes alongside two control cultivars (Kimia and Gachsaran) across three growing seasons (2013–2016) and three locations in Iran (Gachsaran, Ilam, and Khoramabad). A randomized complete block design with three replications was employed at each site.

Mitigating drought stress and enhancing quinoa productivity using iron and zinc nanoparticles
Abstract In recent years, the cultivation area and consumption of quinoa (Chenopodium quinoa Willd) have increased in the country due to its nutritional properties and ability to grow in adverse conditions. Based on climate change scenarios, long periods of drought are expected, which emphasizes the need for planting and developing new plants that are ...

ABSTRACT Background High‐altitude populations typically exhibit elevated hemoglobin (Hb) levels due to chronic hypoxic exposure; however, the impact of this elevation on the risk of ST‐segment elevation myocardial infarction (STEMI) remains unclear. Existing evidence is primarily derived from low‐altitude populations and cannot be directly extrapolated
