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 ...
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 ...
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. ...
Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)
Populations of Euphausia lucens over the shelf of the southern Benguela upwelling
region could be self-maintaining. Alternatively, they could be continually refreshed
by expatriates from the SWAtlantic that enter the ...
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 ...
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. ...
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 ...
A rare new species of the genus Wiborgiella (Crotalarieae, Fabaceae)
(Elsevier, 2014)
The new species Wiborgiella argentea is described. It is closely similar to Wiborgiella leipoldtiana and W. fasciculata
but differs in its single-stemmed habit, densely sericeous leaves, wing petals that are longer than ...
