Data from: Repeated intraspecific divergence in life span and aging of African annual fishes along an aridity gradient
Life span and aging are substantially modified by natural selection. Across species, higher extrinsic (environmentally related) mortality (and hence shorter life expectancy) selects for the evolution of more rapid aging. However, among populations within species, high extrinsic mortality can lead to extended life span and slower aging as a consequence of condition-dependent survival. Using within-species contrasts of eight natural populations of Nothobranchius fishes in common garden experiments, we demonstrate that populations originating from dry regions (with short life expectancy) had shorter intrinsic life spans and a greater increase in mortality with age, more pronounced cellular and physiological deterioration (oxidative damage, tumor load), and a faster decline in fertility than populations from wetter regions. This parallel intraspecific divergence in life span and aging was not associated with divergence in early life history (rapid growth, maturation) or pace-of-life syndrome (high metabolic rates, active behavior). Variability across four study species suggests that a combination of different aging and life-history traits conformed with or contradicted the predictions for each species. These findings demonstrate that variation in life span and functional decline among natural populations are linked, genetically underpinned, and can evolve relatively rapidly.
Weathering by mycorrhizal fungi defines a threshold for nutrients in ecosystems along an aridity gradient - Dataset
<p>Dataset for the Statistical Analysis of Hyphal-Covered Mineral Pellets.<br>This dataset originates from a two-year (2016 to 2018) research project conducted in Chile, spanning locations from Nahuelbuta to Pan de Azúcar (Atacama Desert). It includes detailed records of hyphal growth observed on mineral pellets. Comprehensive descriptions of all methods and data will be available in an upcoming journal publication (DOI will be announced soon).</p>

A test of microclimatic facilitation and shrub canopy volume across the Californian aridity gradient.
<p>In this study, we examined microclimatic parameters, including near-surface air temperature (NSAT), near-surface relative humidity (NSRH), and surface ground temperature (SGT) using a handheld device across seven site in California to test the hypothesis that foundation shrub canopies can provide microclimatic amelioration in dryland ecosystems.</p>
