Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ... -
Sampling bias in reptile occurrence data for the Kruger National Park
(AOSIS, 2020)To effectively conserve and manage species, it is important to (1) understand how they are spatially distributed across the globe at both broad and fine spatial resolutions and (2) elucidate the determinants of these ... -
Sampling bias in reptile occurrence data for the Kruger National Park
(OpenJournals Publishing AOSIS (Pty) Ltd, 2020)To effectively conserve and manage species, it is important to (1) understand how they are spatially distributed across the globe at both broad and fine spatial resolutions and (2) elucidate the determinants of these ... -
Scale insects on ericas : an apparently natural, unnoticeable threat to local biodiversity
(Botanical Society of South Africa, 2008)Introduction: An excursion into the Limietberg Nature Reserve in the Bain's Kloof Mountains during the winter of 2006, one that I have undertaken regularly over the past ten years or so, had revealed a noticeably high ... -
Scale-dependent orientation in movement paths: a case study of an African viper
(Wiley, 2016)Decisions relating to the orientation of movement by animals and how this translates into movement patterns can occur at multiple spatial scales simultaneously, but this interaction is poorly understood for many groups of ... -
Seaweed diversity associated with a Brazilian tropical rhodolith bed
(Universidad Autónoma de Baja California, 2010)This study describes the predominantly tropical, subtidal seaweed populations growing on rhodoliths between 4 and 18 m depth in the southern part of Espírito Santo State (Brazil). Qualitative and quantitative sampling ... -
Seaweeds in two oceans: beta-diversity
(Frontiers Media, 2017)Several species assembly mechanisms have been proposed to structure ecological communities. We assess the biogeography of seaweeds along 2,900 km of South Africa’s coastline in relation to a thermal gradient produced by ... -
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 SW Atlantic that enter the ... -
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 ... -
Sharing for science: High-resolution trophic interactions revealed rapidly by social media
(PeerJ, 2020)Discrete, ephemeral natural phenomena with low spatial or temporal predictability are incredibly challenging to study systematically. In ecology, species interactions, which constitute the functional backbone of ecological ... -
Siphonophores from surface waters of the Colombian Pacific Ocean
(Cambridge University Press, 2018)Siphonophores are colonial hydrozoans that feed on zooplankton including fish larvae, and occur throughout the world’s oceans from surface waters to ocean depths. Here we describe the composition of hyponeustonic siphonophores ... -
Snake body size frequency distributions are robust to the description of novel species
(Ecological Society of America, 2016)The accurate interpretation of body size frequency distributions (BSFDs) has important implications for understanding large-scale ecological and evolutionary patterns because they are shaped by ecological and evolutionary ... -
Snake predators of bird eggs: A review and bibliography
(Wiley, 2022)Snakes are frequent predators of bird nests and therefore potentially have an important impact on bird population dynamics. However, while many species are known to consume nestlings and chicks, few species have been ... -
The South African Astronomical Observatory: a treasure house of history and biodiversity
(Botanical Society of South Africa, 2010)Traces the history of the Royal Observatory Cape of Good Hope, today known as the South African Astronomical Observatory (SAAO). Describes the flora and its management. -
South African seaweed aquaculture: A sustainable development example for other African coastal countries
(Academic Journals, 2013)The green seaweed Ulva is one of South Africa's most important aquaculture products, constituting an important feed source particularly for abalone (Haliotis midae L.), and utilized as a bioremediation tool and other ... -
Specialized morphology, not relatively large head size, facilitates competition between a small-bodied specialist and large-bodied generalist competitors
(Journal of Zoology, 2021)Interspecific competition for limited resources should theoretically occur between species that are morphologically similar to each other. Consequently, species that reduce competition by adapting to specialize on a specific ... -
Stakeholder-derived recommendations and actions to support deep-reef conservation in the Western Indian Ocean
(Wiley, 2022)Deep reefs below 30mprovide essential ecosystem services for ocean health and human well-being such as food security and climate change resilience. Yet, deep reefs remain poorly researched and largely unprotected, including ... -
Status of sperm functionality assessment in wildlife species: From fish to primates
(2021-05)(1) Background: in order to propagate wildlife species (covering the whole spectrum from species suitable for aquaculture to endangered species), it is important to have a good understanding of the quality of their sperm, ... -
Structure of rhodolith beds from 4 to 55 meters deep along the southern coast of Espírito Santo State, Brazil
(Universidad Autónoma de Baja California, 2007)Rhodoliths are one of the most extensive benthic communities of the Brazilian continental shelf, but their structure is poorly known. The richest marine flora of Brazil’s coastal zone is found in Espírito Santo State and ...
