Monetary transfers may be related to patterning in climate events, not just single extreme eventsNARA Subscribed
It is well-documented that households respond to climate events with climate adaptations: risk-management strategies like livelihood diversification, migration, or remittances – sending money and goods across distances. However, the focus is largely on responses to single climate events, while suggestive evidence indicates that temporal and spatial patterns across multiple events – including event frequency, clustering or comp...
Testing sex determining markers in hornbills (Bucerotidae) and ground-hornbills (Bucorvidae)NARA Subscribed
Hornbills (Bucerotidae) and ground-hornbills (Bucorvidae) are families of birds found in Asia and Africa. At least 29 species are considered Near Threatened or above by the IUCN, with hunting for trade being the main threat to these birds. As many species have a unique feature on the top of their beaks called a casque, they are most commonly legally or illegally traded for their skulls or, in the case of the Helmeted Hornbill...
Nonequilibrium spherulitic magnetite in the Ryugu samplesNARA Subscribed
Gynogenetic embryos – those inheriting only maternal DNA – can be experimentally created by fertilizing eggs with radiation‐treated sperm containing inactivated paternal chromosomes. Diploidy in the zygotes can be maintained through prevention of the second meiosis or restored by preventing the first mitosis after the maternal chromosome complement has been replicated. These gynogenetic organisms are useful in many fields incl...
Seagrass meadows commonly reside in shallow sheltered coastal environments which are typically safe havens for mooring boats. There is evidence from around the globe that the use of common swinging chain moorings leads to halos of bare sediment in otherwise productive seagrass. These halos reduce animal abundance and diversity and lead to a loss of the carbon stored within sediments. To protect and enhance seagrass ecosystem s...
Low-Cost, Deep-Sea Imaging and Analysis Tools for Deep-Sea Exploration: A Collaborative Design StudyOA Marine
A minuscule fraction of the deep sea has been scientifically explored and characterized due to several constraints, including expense, inefficiency, exclusion, and the resulting inequitable access to tools and resources around the world. To meet the demand for understanding the largest biosphere on our planet, we must accelerate the pace and broaden the scope of exploration by adding low-cost, scalable tools to the traditional...
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...
