Background and aims Soil water deficits develop at some point during many cropping seasons. To enhance crop drought resilience, cropping characteristics to conserve soil water have often proved desirable. In this paper, two case studies are presented that documented from discovery through to field evaluation the characteristic of initiation of decrease in transpiration rate at comparatively high soil water contents for drought...
Aging is a complex biological process characterized by molecular changes across multiple biological scales. While these alterations have been extensively studied in humans and rodents, the molecular changes associated with aging in dogs remain underexplored despite their relevance as a model for human aging. In this study, we profiled gene expression ( n = 16,273 genes) and protein abundance ( n = 2041 proteins) in whole blood...
Background and aims Previously, triple super phosphate (TSP) application to one soil type was unexpectedly found to cause with soil drying an initiation of linear decrease in maize transpiration rate at an unusually high soil water content. The resulting overall slower soil water extraction resulted in crop drought resilience. A key issue is whether the response occurs with drying of other soils. The objective of this study wa...
Meteorological records at Signy Station in the South Orkney Islands (SOIs) have recently been digitized to cover the period of 1947–1995. This study compares the newly available near‐surface air temperatures at Signy with those from a nearby station, Orcadas and with reanalysis datasets to provide a more comprehensive picture of the weather and climate variability in the SOIs. Temperatures from both stations show a higher degr...

Persistent accelerated epigenetic ageing in a longitudinal cohort of vertically infected HIV-positive adolescentsNARA Subscribed
We have previously shown accelerated ageing in adolescents perinatally infected with HIV (PHIV +), based on discrepancies between epigenetic and chronological age. The current study examines follow-up longitudinal patterns of epigenetic ageing and the association of epigenetic ageing with cognition as well as whole brain structure changes in PHIV + and healthy controls enrolled in the Cape Town Adolescent Antiretroviral Cohort...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
COSORE: A community database for continuous soil respiration and other soil‐atmosphere greenhouse gas flux dataNARA Subscribed
Globally, soils store two to three times as much carbon as currently resides in the atmosphere, and it is critical to understand how soil greenhouse gas (GHG) emissions and uptake will respond to ongoing climate change. In particular, the soil‐to‐atmosphere CO 2 flux, commonly though imprecisely termed soil respiration ( R S ), is one of the largest carbon fluxes in the Earth system. An increasing number of high‐frequency R S...
Variability and change in near‐surface air temperature at 17 Antarctic stations is examined using data from the SCAR READER database. We consider the relationships between temperature, and atmospheric circulation, sea ice concentration and forcing by the tropical oceans. All 17 stations have their largest inter‐annual temperature variability during the winter and the annual mean temperature anomalies are dominated by winter te...
Attending to spatial social–ecological sensitivities to improve trade‐off analysis in natural resource managementNARA Subscribed
Balancing trade‐offs amongst social–ecological objectives is a central aim of natural resource management. However, objectives and resources often have spatial dimensions, which are usually ignored in trade‐off analyses. We examine how simultaneously integrating social–ecological benefits and their spatial complexities can improve trade‐off analysis. We use Pacific herring ( Clupea pallasii, Clupeidae)—an ecologically importan...
