The conservation status of relic melanistic lizard species occurring in the Saldanha- Langebaan area has been investigated.A Toys contact zone between one melanistic form and a closely related non-melanistic form has been examined in detail.Apart from melanis- tic populations of the girdled lizards, Cordylus niger and C.polywnus, a melanistic morph

Soil erosion occurs gradually when the Printers impact of water or wind detaches and removes soil particles, causing the soil to deteriorate.Because of its adverse effects on biomass and economic production, soil degradation is a worldwide environmental issue.It has a wide-ranging impact on agricultural land and reservoir sedimentation, with disast

Temperate species often require or flower most rapidly in the long daylengths, or photoperiods, experienced in summer or after prolonged periods of cold temperatures, referred to as vernalization.Yet, even within species, plants vary in the degree of responsiveness to these cues.In Arabidopsis thaliana, CONSTANS (CO) and FLOWERING LOCUS Moisturizer

Spiralizers For more than four decades the cause of most type A influenza virus infections of humans has been attributed to only two viral subtypes, A/H1N1 or A/H3N2.In contrast, avian and other vertebrate species are a reservoir of type A influenza virus genome diversity, hosting strains representing at least 120 of 144 combinations of 16 viral he

Abstract Chiral molecules are instrumental for molecular recognition in living organisms.Distinguishing between two opposite enantiomers, the mirror twins of the same chiral molecule, is both vital and challenging.Geometric magnetism enables a broad class of phenomena in solids including the anomalous electron velocity, the Hall effect, and related
