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. ...
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)
The process of species description is not random, and understanding the factors that in-
fluence when a species is first described (the date of first description, DoFD) allows us to
target environments and/or species' ...
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 ...
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. ...
Null models for null hypotheses in taxonomy: A test using Scyphozoa
(Oxford University Press, 2021)
Although molecular tools are becoming more important in the delineation of scyphozoan species there is,
perforce, a need to substantiate new species definitions using morphological data. Access to type material
is often ...
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 ...
The effect of anthropogenic noise and weather conditions on male calls in the bladder grasshopper Bullacris unicolor
(Taylor and Francis Group, 2021)
Acoustic communication in animals relies upon specificcontextsandenvironments for effective signal transmission. Increasing anthropo-genic noise pollution and different weather conditions can disruptacoustic communication. ...
Environmental response and ph tolerance of induced co2 in ulva rigida c.agardh, 1823(Chlorophyta) under controlled conditions
(PAS FORUM, 2022)
The increase in integrated multitrophic aquaculture (IMTA), where seaweed (particularly Ulva rigidaC.Agardh, 1823) is
used as a feedstock and a wastewater scrubber in South African IMTA systems, has necessitated research ...
A taxonomic revision of chamaecrista (caesalpinioideae, cassieae, cassiinae) in Southern Africa
(American Society of Plant Taxonomists, 2022)
The southern African species of Chamaecrista were all treated under Cassia in Gordon-Gray’s treatment for the Flora of Southern
Africa. However, given the subsequent generic recircumscriptions in the subtribe Cassiinae, ...
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 ...
