A blueprint for integrating scientific approaches and international communities to assess basin-wide ocean ecosystem status
(Nature Research, 2023)
Ocean ecosystems are at the forefront of the climate and biodiversity crises, yet we lack a
unified approach to assess their state and inform sustainable policies. This blueprint is
designed around research capabilities ...
In a rough spot: Declines in Arthroleptella rugosa calling densities are explained by invasive pine trees
(Wiley, 2023)
Basing conservation interventions on evidence is important for justifying their associated cost and gauging their effectiveness. For amphibians, the number of studies available to support conservation ...
Temporal partitioning of Bullacris unicolor (Orthoptera: Pneumoridae) calling activity to avoid predation
(Taylor and Francis Group, 2023)
Ecological interactions, including competition, predation, and environmental conditions, may significantly impact acoustic signal-ling behaviour. Here we characterise nocturnal signalling patterns in the bladder grasshopper ...
Biocontrol Potential of Bacillus subtilis and Bacillus tequilensis against Four Fusarium Species
(MDPI, 2023)
The use of biological control agents as opposed to synthetic agrochemicals to control
plant pathogens has gained momentum, considering their numerous advantages. The aim of this
study is to investigate the biocontrol ...
African rangelands and pastoralism in a changing continent: Perspectives and opportunities
(Taylor and Francis Group, 2023)
Eighty-five years ago, Africa was described as a land of promise because it provided an immense opportunity for maximum return in the minimum time (Olaniyan 2000). It was treated this way because ...
Phylogeographic investigation of the bladder grasshopper Bullacris unicolor (Orthoptera Pneumoroidea) in South Africa
(Taylor and Francis Group, 2023)
There are several factors, such as genetic drift, gene flow and migration that affect the population genetic structure and phylogeographic distribution of genetic lineages within single species. Previous studies of the ...
Transhumance pastoralism in West Africa – its importance, policies and challenges
(African Journal of Range & Forage Science, 2023)
The Economic Community of West African States (ECOWAS) recognises transhumance pastoralism as a beneficial livestock production system that can contribute to food security together with economic and political stability. ...
Iterative mapping of marine ecosystems for spatial status assessment, prioritization, and decision support
(Frontiers Media, 2023)
South Africa has taken an iterative approach to marine ecosystem mapping over
18 years that has provided a valuable foundation for ecosystem assessment,
planning and decision-making, supporting improved ecosystem-based ...
Is penguin circovirus circulating only in the antarctic circle? Lack of viral detection in namibia
(MDPI, 2023)
The known host range of circoviruses is continuously expanding because of more intensive diagnostic activities and advanced sequencing tools. Recently, a new circovirus (penguin
circovirus (PenCV)) was identified in the ...
Nitrogen fertilization increases the growth and nutritional quality of the forage legume, Calobota sericea – A preliminary investigation
(Elsevier, 2023)
Calobota sericea is being evaluated as a forage for drought stressed areas. The nutritional quality
of C. sericea from native populations are poor, and this is believed to be due to poor soil fertility.
Therefore, a ...
