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 ... -
Carbon stock prediction in managed forest ecosystems using Bayesian and frequentist geostatistical techniques and new generation remote sensing metrics
(MDPI, 2023)The study compares the performance of a hierarchical Bayesian geostatistical methodology with a frequentist geostatistical approach, specifically, Kriging with External Drift (KED), for predicting C stock using prediction ... -
A cursory look at the fishmeal/oil industry from an ecosystem perspective
(Frontiers Media, 2021)By supporting the fishmeal industry, are we competing with marine predators? Should we be taking away food from marine predators to subsidize agriculture? If not for human consumption, should forage fish be left in the ... -
From benthic to floating: phytoplankton dynamics in African freshwater lakes and reservoirs
(Elsevier, 2023)This chapter reviewed phytoplankton communities in African freshwater lakes and reservoirs and further assessed the latitudinal diversity gradient (LDG) which has been used to explain species variations in other taxonomic ... -
From conflict to collaboration: Atewa forest governance
(Taylor and Francis Group, 2023)The problem of forest degradation and loss has become theconcern of many countries. To address this challenge, somecollaborate in sustainable forest management. The mostsuccessful outcomes, however, are observed where ... -
Geometagenomics illuminates the impact of agriculture on the distribution and prevalence of plant viruses at the ecosystem scale
(Nature Publishing Group, 2018)Disease emergence events regularly result from human activities such as agriculture, which frequently brings large populations of genetically uniform hosts into contact with potential pathogens. Although viruses cause ... -
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 ... -
Landsat-8 and sentinel-2 based prediction of forest plantation c stock using spatially varying coefficient Bayesian hierarchical models
(MDPI, 2022)This study sought to establish the performance of Spatially Varying Coefficient (SVC) Bayesian Hierarchical models using Landsat-8, and Sentinel-2 derived auxiliary information in predicting plantation forest carbon (C) ... -
Porolithon improcerum (porolithoideae, corallinaceae) and mesophyllum macroblastum (melobesioideae, hapalidiaceae): New records of crustose coralline red algae for the Southwest Atlantic Ocean
(Magnolia Press, 2014)Here we describe in detail two crustose coralline red algal (CCA) species newly reported for the southern Atlantic: Porolithon improcerum and Mesophyllum macroblastum. Porolithon improcerum was recorded on the remote ... -
A quarter century of marine biodiscovery in Algoa bay, South Africa
(Journal of Natural Products, 2023)Algoa Bay, the largest crenulate bay on the south-eastern coast of South Africa, is currently one of the most well-studied marine ecosystems in southern Africa. A plethora of endemic marine invertebrates inhabits the benthic ...
