Too hot to nest? In a hot summer the tortoise Chersina Angulata can switch from nesting to facultative viviparity
(Frontiers Media, 2022)
In a captive colony of Chersina angulata in Cape Town, South Africa, we observed
in 2015/16 retention of the last egg clutch inside the female until the hatching stage
was reached, conforming to the generally accepted ...
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, ...
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
.

South Africa is located at an ecologically important ...
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 ...
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. ...
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 ...
Climate change in coastal waters: Time series properties affecting trend estimation
(AMS, 2016)
In South Africa, 129 in situ temperature time series of up to 43 years are used for investigations of the
thermal characteristics of coastal seawater. They are collected with handheld thermometers or underwater
temperature ...
Biomass partitioning in an endemic southern African salt marsh species Salicornia tegetaria (Chenopodiaceae)
(Taylor and Francis Group, 2020)
The below ground biomass of salt marsh species accounts for more than half of the total plant biomass in salt marsh systems, yet no biomass data exist for salt marsh species in South Africa. ...
Metabarcoding of zooplankton to derive indicators of pelagic ecosystem status
(Academy of Science of South Africa, 2022)
Zooplankton play a key role in marine food webs and carbon cycling and are useful indicators of climate-related changes and ocean health in pelagic ecosystems. Zooplankton are traditionally identified to species through ...
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
(Wiley, 2022)
Latitudinal range limits for mangroves on high-energy,
wave-dominated
coasts
are controlled by geomorphological features and estuarine dynamics. Mangroves
reach a southern global range limit along the South African ...
