Nutrients composition in fit snacks made from ostrich, beef and chicken dried meat
(MDPI, 2018)The aim of the study was to compare three types of meat snacks made from ostrich, beef, and chicken meat in relation to their nutrients content including fat, fatty acids, heme iron, and peptides, like anserine and carnosine, ... -
Health expenditure, child and maternal mortality nexus : a comparative global analysis
(BioMed Central, 2018-07)Background: This paper provides empirical evidence on how the relationship between health expenditure and health outcomes varies across countries at different income levels. Method: Heterogeneity and cross-section ... -
Why do models of insect respiratory patterns fail?
(Company of Biologists, 2018)Insects exchange respiratory gases using an astonishing diversity of patterns. Of these, discontinuous gas exchange cycles (DGCs) have received the most study, but there are many other patterns exhibited intraspecifically ... -
Insect-flower interaction networks vary among endemic pollinator taxa over an elevation gradient
(Public Library of Science, 2018-11-29)Interaction networks are sensitive to elevation gradients through changes in local distribution of interacting partners. Here, we use plant-pollinator interaction network metrics to assess the effect of elevation on flowers ... -
Artificial reservoirs complement natural ponds to improve pondscape resilience in conservation corridors in a biodiversity hotspot
(Public Library of Science, 2018-09-20)Natural ponds are rich in biodiversity, contributing greatly to regional aquatic biodiversity. Artificial reservoirs used for irrigation can be significant additional features of the landscape. They infill the local natural ... -
Only multi-taxon studies show the full range of arthropod responses to fire
(Public Library of Science, 2018-04-03)Fire is a major driver in many ecosystems. Yet, little is known about how different ground-living arthropods survive fire. Using three sampling methods, and time-since-fire (last fire event: 3 months, 1 year, and 7 years), ... -
High nitrogen rates do not increase canola yield and may affect soil bacterial functioning
(American Society of Agronomy, 2019)Nitrogen fertilization has a fundamental role in agricultural productivity. However, injudicious N applications to crops are common. It is important to ensure the minimum N required for satisfactory crop growth is applied ... -
Development of a richer measure of health outcomes incorporating the impacts of income inequality, ethnic diversity, and ICT development on health
(BMC (part of Springer Nature), 2018)Background: In the literature, measuring health outcomes usually entails examining one dependent variable using cross-sectional data. Using a combination of mortality and morbidity variables, this study developed a new, ... -
Investigating the effect of selected non-saccharomyces species on wine ecosystem function and major volatiles
(Frontiers Media, 2018-11-13)Natural alcoholic fermentation is initiated by a diverse population of several non-Saccharomyces yeast species. However, most of the species progressively die off, leaving only a few strongly fermentative species, mainly ... -
Testing the sensitivity of potential panelists for wine taint compounds using a simplified sensory strategy
(MDPI, 2018-10-24)The odor detection threshold (ODT) of a compound is the lowest concentration at which individuals can reliably perceive a difference between a sample and its corresponding control, with 50% performance above chance. Wine ... -
Measuring thiols in single cultivar South African red wines using 4,4-dithiodipyridine (DTDP) derivatization and ultraperformance convergence chromatography-tandem mass spectrometry
(MDPI, 2018-08-30)Wine varietal thiols are important contributors to wine aroma. The chemical nature of thiols makes them difficult to measure due to low concentrations, high sensitivity to oxidation, and low ionization. Methods for the ... -
Functional and phylogenetic diversity determine woody productivity in a temperate forest
(Wiley Open Access, 2018)ENGLISH ABSTRACT: Understanding the relationships between biodiversity and ecosystem productivity has become a central issue in ecology and conservation biology studies, particularly when these relationships are connected ... -
Plant functional trait data and reflectance spectra for 22 palmiet wetland species
(Elsevier, 2018)We provide reflectance spectra for 22 South African palmiet wetland species collected in spring 2015 from three wetlands throughout the Cape Floristic Region. In addition, we provide summarized plant functional trait data, ... -
Carnitine requires choline to exert physiological effects in saccharomyces cerevisiae
(Frontiers Media, 2018-07-02)L-Carnitine is a key metabolite in the energy metabolism of eukaryotic cells, functioning as a shuttling molecule for activated acyl-residues between cellular compartments. In higher eukaryotes this function is essential, ... -
Bibliometric and social network analysis in scientific research on precision agriculture
(Indian Academy of Sciences, 2018-11-10)Precision agriculture (PA) is used to improve agricultural processes. A better understanding of PA as well as the evolution of the research status through the available literature are reported and discussed in this study. ... -
New policy directions for global pond conservation
(Wiley Open Access, 2018)Despite the existence of well‐established international environmental and nature conservation policies (e.g., the Ramsar Convention and Convention on Biological Diversity) ponds are largely missing from national and ... -
Increase anti-poaching law-enforcement or reduce demand for wildlife products? A framework to guide strategic conservation investments
(Wiley Open Access, 2018)Donors, NGOs, and governments increasingly invest in campaigns to reduce con-sumer demand for wildlife products in an attempt to prevent the decline of overex-ploited and poached species. We provide a novel framework to ... -
The effect of extensive human presence at an early age on stress responses and reactivity of juvenile ostriches towards humans
(MDPI -, 2018)The effect of extensive human presence and regular gentle handling performed at an early age (0–3 months old) on stress responses and reactivity of juvenile ostriches towards humans was investigated. A total of 416 ostrich ... -
A comparison of two methods of data collection for modelling productivity of harvesters : manual time study and follow-up study using on-board-computer stem records
(Marin Dracea National Research-Development Institute in Forestry, 2018)Abstract. Productivity of a mechanized P. patula cut-to-length harvesting operation was estimated and modelled using two methods of data collection: manual time study and follow-up study using StanForD stem files. The ... -
Response of soil chemical properties to irrigation with winery wastewater on a well-drained sandy soil
(South African Society for Enology and Viticulture, 2019)Most wineries in South Africa dispose of their wastewater through land application. This is carried out by irrigating small areas of cultivated pasture with the wastewater or ponding, with the former being the more general ...
