In silico analysis of a putative dehalogenase from the genome of halophilic bacterium Halomonas smyrnensis AAD6T
(Taylor and Francis, 2022)Microbial-assisted removal of natural or synthetic pollutants is the prevailing green, low-cost technology to treat polluted environments. However, the challenge with enzyme-assisted bioremediation is the laborious nature ... -
Detecting marine heatwaves with sub-optimal data
(Frontiers, 2019)Marine heatwaves (MHWs), or prolonged periods of anomalously warm sea water temperature, have been increasing in duration and intensity globally for decades. However, there are many coastal, oceanic, polar, and sub-surface ... -
Seed germination and early seedling growth responses to drought stress in annual Medicago L. And Trifolium L. Forages
(MDPI, 2022)Climate change in the Mediterranean-like regions of South Africa has resulted in increased rainfall variability, a delayed start to the wet winter season, and increased occurrences of out-ofseason summer rainfall events. ... -
Ancient mitogenomics clarifies radiation of extinct Mascarene giant tortoises (Cylindraspis spp.)
(Nature research, 2019)The five extinct giant tortoises of the genus Cylindraspis belong to the most iconic species of the enigmatic fauna of the Mascarene Islands that went largely extinct after the discovery of the islands. To resolve the ... -
Epizootic ulcerative syndrome – first report of evidence from South Africa's largest and premier conservation area, the Kruger National Park
(ScienceDirect, 2019)This study reports on the first evidence of genomic material of the causative agent for epizootic ulcerative syndrome (EUS), Aphanomyces invadans, from fish in the Limpopo River system and the Kruger National Park, South ... -
First record of the water mold achlya bisexualis (saprolegniaceae) isolated from ornamental fish in south africa
(American fisheries society, 2019)The order Saprolegniales (Class Oomycota) is a group of fungus-like eukaryotic microorganisms that have been associated with infections in fish and fish eggs. Infections with microorganisms from this order are clearly ... -

Mechanisms of interference and exploitation competition in a guild of encrusting algae along a South African rocky shore
(University of the Western Cape, 2019)Within the marine benthos, space is considered an absolute requirement that is often in limited supply. The often-low availability of this essential resource causes species to interact competitively through mechanisms of ... -
A tale of two habitats: preliminary comparison of fish abundance and diversity between saltmarsh- and mangrove-dominated creeks in the Nahoon Estuary, South Africa
(University of the Western Cape, 2019)A preliminary assessment of abundance and richness of fishes utilising saltmarsh and mangrove habitats in the Nahoon Estuary, situated on the eastern coast of South Africa, was undertaken during July 2017. The structural ... -
DRIFT incorporating an eco-social system network and time series approach into environmental flow assessments
(Taylor & Francis, 2022)DRIFT (Downstream Response to Imposed Flow Transformation) is an interactive, ecological-social process and software package to assist with environmental flow assessments and river management decision-making. It was ... -
Happy Feet in a Hostile World? The Future of Penguins Depends on Proactive Management of Current and Expected Threats
(2019)Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 penguin species are decreasing. Here we present a review that ... -
Predicting Shifts in the geographical distribution of two estuarine plant species from the subtropical and temperate regions of South Africa
(Springer, 2019-11-21)Climate suitability maps are useful to determine changes in the distribution of species. The aim of this study was to predict the future distribution of two estuarine species (Bassia diffusa and Hibiscus tiliaceus) from ... -
Intercolony variation in reproductive skipping in the African penguin
(Wiley Open Access, 2022)In long-lived species, reproductive skipping is a common strategy whereby sexually mature animals skip a breeding season, potentially reducing population growth. This may be an adaptive decision to protect survival, or ... -
Pineapple stem-derived bromelain based priming improves pepper seed protein reserve mobilization, germination, emergence and plant growth
(Springer, 2021)Pepper seeds are slow to germinate and emergence is often non-uniform and incomplete, reducing gains from this cash crop. This study investigated the effects of pineapple stem- derived protease (stem bromelain) based priming ... -
Marine seismic surveys for hydrocarbon exploration: What’s at stake?
(Academy of Science of South Africa, 2022)With a coastline extending approximately 3900 km, South Africa exercises jurisdiction over a vast Exclusive Economic Zone (EEZ) that exceeds 1.5 million km2 . 1 South Africa is located at an ecologically important ... -
Giants and titans: First records of the invasive acorn barnacles Megabalanus tintinnabulum (Linnaeus, 1758) and Megabalanus coccopoma (Darwin, 1854) on intertidal rocky shores of South Africa
(Regional Euro-Asian Biological Invasions Centre (REABIC), 2022)During intertidal rocky shore surveys on the east coast of South Africa in 2018, the non-indigenous giant purple barnacle Megabalanus tintinnabulum (Linnaeus, 1758), a well-known fouling and globally-invasive species, ... -
Oligosaccharides production from coprophilous fungi: An emerging functional food with potential health-promoting properties
(Elsevier, 2022)Functional foods are essential food products that possess health-promoting properties for the treatment of infectious diseases. In addition, they provide energy and nutrients, which are required for growth and survival. ... -
Community and marine conservation in South Africa: Are we still missing the mark?
(Frontiers Media, 2022)Marine Protected Areas (MPAs) in South Africa have a long history with currently 5% of the mainland’s ocean territory protected. The MPAs are celebrated and appreciated for their representative coverage of several habitat ... -
Yeast supplementation alleviates the negative effects of greywater irrigation on lettuce and maize
(South African Water Research Commission, 2022)Water scarcity has led to increased use of wastewater, particularly greywater, for crop irrigation. This study investigated whether the addition of yeast can alleviate the potential negative effects of greywater use on ... -
