First abundance estimates of heaviside’s (cephalorhynchus heavisidii) and dusky (lagenorhynchus obscurus) dolphins off namibia using a novel visual and acoustic line transect survey
(Frontiers Media, 2020)Knowledge of a population’s abundance is of primary importance for conservation management. However, robust estimates of abundance are often difficult to obtain, especially for cetaceans which spend most of their lives ... -
Multi-model seascape genomics identifies distinct environmental drivers of selection among sympatric marine species
(BMC (part of Springer Nature), 2020-09-16)Background: As global change and anthropogenic pressures continue to increase, conservation and management increasingly needs to consider species’ potential to adapt to novel environmental conditions. Therefore, it ... -
Socioeconomic inequalities in food insecurity and malnutrition among underfive children : within and between-group inequalities in Zimbabwe
(BioMed Central, 2020-08-04)Background: Food insecurity and malnutrition in children are pervasive public health concerns in Zimbabwe. Previous studies only identified determinants of food insecurity and malnutrition with very little efforts done ... -
The implication of chemotypic variation on the anti-oxidant and anti-cancer activities of sutherlandia frutescens (L.) R.Br. (Fabaceae) from different geographic locations
(MDPI, 2020)Extracts of Sutherlandia frutescens (cancer bush) exhibit considerable qualitative and quantitative chemical variability depending on their natural wild origins. The purpose of this study was thus to determine bioactivity ... -
Malaria patterns across altitudinal zones of Mount Elgon following intensified control and prevention programs in Uganda
(BMC (part of Springer Nature), 2020-06-17)Background: Malaria remains a major tropical vector-borne disease of immense public health concern owing to its debilitating effects in sub-Saharan Africa. Over the past 30 years, the high altitude areas in Eastern Africa ... -
Academic leaders must support inclusive scientific communities during COVID-19
(Springer Nature, 2020)The COVID-19 pandemic poses major challenges for all sectors of society, including scientists faced with abrupt disruptions and redirections of research and higher education1. The consequences of this crisis ... -
MicroCT imaging applied to description of a new species of Pagurus Fabricius, 1775 (Crustacea: Decapoda: Anomura: Paguridae), with selection of three-dimensional type data
(Public Library of Science, 2018)A new species of hermit crab, Pagurus fraserorum n. sp. (family Paguridae) is described from rocky subtidal reefs off KwaZulu-Natal, South Africa, and illustrated using both conventional drawings and colour photographs, ... -
Monitoring consumptive resource use in South African national parks
(AOSIS, 2019-01-30)Monitoring is an essential component of measuring the performance of protected areas. This requirement led to the development of a biodiversity monitoring system for South African National Parks (SANParks). The system ... -
All-in-one : physics, chemistry and ecology are essential fields to thermal ecologists
(International Biogeography Society, 2018)The book clearly targets principles that are essential for understanding the relationship between temperature and organisms and does not represent a book for applications on how to do measurements or complex tasks in thermal ... -
Frontiers of Biogeography : taking its place as a journal of choice for the publication of high quality biogeographical research articles
(International Biogeography Society, 2018)Through this editorial we seek your support and engagement as authors, readers and reviewers as we take the next steps in developing Frontiers of Biogeography as a leading international journal of biogeography and ... -
Koedoe : African Protected Area Conservation and Science - a retrospection : 1958 to 2018
(AOSIS, 2019-04-08)In 2018, Koedoe celebrated an unbroken publication record of 60 years. From uncertain beginnings in 1958, it is now a mature and important internationally recognised scientific journal focussing on conservation and science ... -
High resolution temperature data for ecological research and management on the Southern Ocean Islands
(Nature Research, 2018-09-04)Southern Ocean Islands are globally significant conservation areas. Predicting how their terrestrial ecosystems will respond to current and forecast climate change is essential for their management and requires high-quality ... -
GlobTherm, a global database on thermal tolerances for aquatic and terrestrial organisms
(Nature Research, 2018-03-13)How climate affects species distributions is a longstanding question receiving renewed interest owing to the need to predict the impacts of global warming on biodiversity. Is climate change forcing species to live near ... -
GloPL, a global data base on pollen limitation of plant reproduction
(Nature Research, 2018-11-20)Plant reproduction relies on transfer of pollen from anthers to stigmas, and the majority of flowering plants depend on biotic or abiotic agents for this transfer. A key metric for characterizing if pollen receipt is ... -
Plant diversity drives global patterns of insect invasions
(Nature Research, 2018)During the last two centuries, thousands of insect species have been transported (largely inadvertently) and established outside of their native ranges worldwide, some with catastrophic ecological and economic impacts. ... -
Mitochondrial DNA is unsuitable to test for isolation by distance
(Nature Research, 2018-05-31)Tests for isolation by distance (IBD) are the most commonly used method of assessing spatial genetic structure. Many studies have exclusively used mitochondrial DNA (mtDNA) sequences to test for IBD, but this marker is ... -
Geographic variation and plasticity in climate stress resistance among southern African populations of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae)
(Nature Research, 2018-06-29)Traits of thermal sensitivity or performance are typically the focus of species distribution modelling. Among-population trait variation, trait plasticity, population connectedness and the possible climatic covariation ... -
Bedreig antropogeniese omgewingsveranderinge grondbiodiversiteit?
(AOSIS, 2018)ENGLISH ABSTRACT: Soil is a service providing asset under growing pressure but it is also home to an array of soil-dwelling species encompassing virtually all terrestrial invertebrate phyla. The impact humaninduced change ... -
Publication incentives based on journal rankings disadvantage local publications
(Academy of Science of South Africa, 2018-09-11)No abstract available. -
Interactions among predators and plant specificity protect herbivores from top predators
(Ecological Society of America, 2018)The worldwide loss of top predators from natural and agricultural systems has heightened the need to understand how important they are in controlling herbivore abundance. The effect of top predators on herbivore species ...
