Cinnabar is the more stable form, and is a structure akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. [5]
Cinnabar moth (Tyria jacobaeae) caterpillar feeding on a Senecio. The seed of common groundsel is a good green food for canaries and finches and it is available all year round. [9] Senecio vulgaris seed has been found in the droppings of sparrows, and seedlings have been raised from the excreta of various birds. Seed has also been found in cow ...
Bullock team at Cinnabar, circa 1900. In 1872, the mineral cinnabar (a sulphide of mercury) was found on the sheep station of J.D. Mactaggart west of Kilkivan. The heavy dark-red stones found contained 24% mercury in addition to copper selenide. Mercury was extensively used in gold production in Australia at that time, but no significant ...
Hardy cyclamen planted in ground are rarely bothered by pests. Rodents may dig up the tubers, so plant them in bulb baskets underground or in DIY cages made from chicken wire. Hardy Cyclamen Toxicity
red cinnabar (α-HgS, trigonal, hP6, P3221) is the form in which mercury is most commonly found in nature. Cinnabar has rhombohedral crystal system. Crystals of red are optically active. This is caused by the Hg-S helices in the structure. [5] black metacinnabar (β-HgS) is less common in nature and adopts the zinc blende crystal structure (T 2 ...

Groundcover of Vinca major. Groundcover or ground cover is any plant that grows low over an area of ground, which protects the topsoil from erosion and drought.In a terrestrial ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer, and provides habitats and concealments for (especially fossorial) terrestrial fauna.
