The ephemerals of Namaqualand: Effect of germination date on parameters of growth analysis of three species
TL;DR: Seasonal changes in relative growth rate as well as leaf area ratio observed in plants which developed from seed sown on different dates, reflected the interaction between ontogenetic and environmental factors.

The effect of leaching and irrigation on the growth of Atriplex semibaccata
TL;DR: In this paper, the influence of leaching depth and the amount and frequency of irrigation on the growth of Atriplex semibaccata R. Br. C. was investigated.

Competitive ability of two grass species: Anthephora pubescens and Eragrostis curvula. 1. Yield and biomass allocation
TL;DR: The values of the relative yield per plant and aggressivity obtained in the present study all indicate that A. pubescens is a poor competitor, while E. curvula is a strong competitor and would probably eventually eliminate A.pubescens.

Anatomy of myxospermic diaspores of selected species in the Succulent Karoo, Namaqualand, South Africa
TL;DR: This study investigated the origin of the mucilaginous layer of 12 species anatomically, using both light and scanning electron microscopy and found that the mucilage production of the species investigated could best be grouped into three types: 1, epidermal and sub-epidermal cells of seeds and achenes; 2, specialized tissue in wings or the pappus of achene; and 3, mucilage excreting hairs.
Using fourth-year medical students' reflections to propose strategies for primary care physicians, who host students in their practices, to optimise learning opportunities
TL;DR: A qualitative approach to analyse the narratives of the photo-story reports was used and strategies that could be implemented by the primary healthcare practitioners to optimise the learning experience of students in their practices were proposed.
