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 ...
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]
The seeds are 4–5 mm (0.16–0.20 in) in diameter and weigh on average 68 mg. [5] The berries exude a deep red resin, known as dragon's blood. [6] Like other monocotyledons, such as palms, the dragon's blood tree grows from the tip of the stem, with the long, stiff leaves borne in dense rosettes at the end. It branches at maturity to produce ...
The achenes have dandelion-like groups of prickly hairs called pappuses, which help seed dispersal by the wind. [ 9 ] [ 10 ] The number of seeds produced may be as large as 75,000 to 120,000, although in its native range in Eurasia very few of these would grow into new plants and research has shown that most seeds do not travel a great distance ...
The cinnabar moth (Tyria jacobaeae) is a brightly coloured arctiid moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand , Australia and North America to control ragwort , on which its larvae feed.
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.
This tree is useful for nitrogen fixation, and it is often cultivated for forage, as an ornamental garden plant or urban tree, and as a medicinal plant. For example, the young leaves can be cooked and eaten. The raw seeds are toxic, but may be eaten when cooked. [6] In Singapore, the species forms part of the diet of local Raffles' banded ...
Zingiberaceae (/ ˌ z ɪ n dʒ ɪ b ɪ ˈ r eɪ s i. iː /) or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species [4] of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas.
