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 ...
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 ...
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 ...
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, ...
2-phenoxyethanol as anaesthetic in removing and relocating 102 species of fishes representing 30 families from sea world to uShaka Marine World, South Africa
(AOSIS, 2008)
The South African Association for Marine Biological
Research, incorporating Sea World, Oceanographic
Research Institute and the Dolphinarium relocated
from their old premises of 46 years on Durban’s
beach front in March ...
