Features of possible regional ionospheric memory manifested themselves at low-latitudes under solar eclipse conditions.
Hierarchical soil–plant buffering stabilizes nutrient dynamics in citrus under sustained irrigation with contrasting water chemistriesNARA Subscribed
Background and aims The increasing use of non-conventional water resources in Mediterranean agriculture raises concerns regarding nutrient imbalances and the capacity of soils to buffer irrigation-driven chemical inputs. This study evaluated how the soil–plant system stabilizes plant nutritional status under irrigation with contrasting water chemistries. Methods Nutrient dynamics were assessed along the soil–water–plant contin...
Cryptic coral reef microhabitats and the functional role of brittle stars in biogenic sediment generationNARA Subscribed
Recent studies have highlighted the ecological importance of cryptic habitat space on coral reefs. These microhabitats, ranging from framework cavities to intra-branch space within marine macroalgae, can harbour diverse and ecologically relevant taxa. Here we show that brittle stars, ubiquitous across such cryptic habitats (reported densities exceeding 100 ind. m −2 ), represent an important, but previously neglected, source o...
Plant growth-promoting bacteria mitigate drought stress in a new forage oat variety (Avena sativa AV25T)NARA Subscribed
Background and Aims Climate change is posing a major threat to global agricultural productivity. Plant growth-promoting bacteria (PGPB) have emerged as sustainable tools to enhance crop tolerance to abiotic stress through different mechanisms. This study aimed to evaluate the physiological, biochemical, and transcriptomic responses of the Altoandina oat variety ( Avena sativa AV25T) under water deficit and to determine the eff...
Lettuce Growth Under Desalinated Seawater Irrigation: Effects on Yield, Nutrient Uptake, and Soil PropertiesNARA Subscribed
The use of non-conventional water sources, such as desalinated seawater (DSW), for agricultural irrigation is increasing in arid and semi-arid regions, raising concerns about potential impacts on crop physiology, productivity, and soil health. This study assessed the agronomic effects of DSW irrigation on iceberg lettuce ( Lactuca sativa var. capitata ) grown over four consecutive seasons in outdoor pallet boxes. Three water q...
The Mongolian Gerbil ( Meriones unguiculatus ) diverged from rats/mice around 45 million years ago and developed adaptations to extreme temperatures and water scarcity. Another feature of the Mongolian Gerbils is their social monogamy similar to that of prairie voles. These observations suggest that there are potential differences in the Mongolian Gerbil brain that are distinct from that of rats and mice. The goal of the prese...
Native Australian seedlings exhibit novel strategies to acclimate to repeated heatwave eventsNARA Subscribed
Heatwaves are becoming more intense and frequent. Plant photosystem thermal thresholds can vary with species, but also shift in response to environmental triggers. Both upper and lower thresholds can acclimate to repeated heatwaves through ecological stress memory, where prior exposure primes them for subsequent events. The extent to which acclimation to repeated heat stress events varies among environmental origin and/or spec...
