A deep search for faint galaxies associated with very low-redshift C iv absorbers: A case with cold-accretion characteristics
(The American Astronomical Society, 2013)Studies of QSO absorber–galaxy connections are often hindered by inadequate information on whether faint/dwarf galaxies are located near the QSO sight lines. To investigate the contribution of faint galaxies to QSO ... -
Deep-sea fisheries as resilient bioeconomic systems for food and nutrition security and sustainable development
(Elsevier, 2023)population, contributing to a substantial shift toward fishing in the mesopelagic zone. These areas contain a potentially huge amount of fish biomass. Considering that the global population will demand an increase of ... -
Deepening democracy: A farm workers’ movement in the Western Cape
(Taylor & Francis, 2010)This article explores the internal dynamics and external impact of a South African farm workers’ movement, Sikhula Sonke. It looks at the extent to which this women-led ‘social movement trade union’ has succeeded in ... -
Deeper knowledge of shallow waters: reviewing the invertebrate fauna of southern African temporary wetlands
(Spring Nature Limited, 2018)Temporary lentic wetlands are becoming increasingly recognised for their collective role in contributing to biodiversity at the landscape scale. In southern Africa, a region with a high density of such wetlands, ... -

Defining regional and local sediment sources in the ancestral Colorado River system: A heavy mineral study of a mixed provenance unit in the Fish creek-vallecito basin, Southern California
(MDPI, 2023)The Colorado River has flowed across the dextral strike-slip plate boundary between the North American and Pacific plates since the latest Miocene or earliest Pliocene. The Fish Creek- Vallecito Basin (FCVB) lies on the ... -
Defining Terms Used for Animals Working in Support Roles for People with Support Needs
(MDPI, 2022)The nomenclature used to describe animals working in roles supporting people can be confusing. The same term may be used to describe different roles, or two terms may mean the same thing. This confusion is evident among ... -
Defining the molecular signatures of Achilles tendinopathy and anterior cruciate ligament ruptures: A whole-exome sequencing approach
