Convolvulus is a genus of about 250 species of flowering plants in the bindweed family Convolvulaceae, with a cosmopolitan distribution. Common names include bindweed and morning glory, both names shared with other closely related genera. They are annual or perennial herbaceous vines and (a few species) woody shrubs, growing to 0.3-3 m tall. The leaves are spirally arranged, and the flowers trumpet-shaped, mostly white or pink, but blue, violet, purple or yellow in some species. Many of the species are problematic weeds, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive flowers. However, some other species are globally threatened.

Taraxacum is a large genus of flowering plants in the family Asteraceae. They are native to Europe, North America and Asia and two species, T. officinale and T. erythrospermum, are found as weeds worldwide. The common name Dandelion is given to members of the genus and like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret. Many Taraxacum species produce seeds asexually by apomixis, where the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant.

In agriculture, a set of harrows is an implement for cultivating the surface of the soil. In this way it is distinct in its effect from the plough, which is used for deeper cultivation. Harrowing is often carried out on fields to follow the rough finish left by ploughing operations. The purpose of this harrowing is generally to break up clods and lumps of soil and to provide a finer finish, and a good soil structure that is suitable for seeding and planting operations. Coarser harrowing is used to remove weeds and to cover seeds after sowing.

The Great Crested Grebe (Lophæthyia cristata) is a fresh-water, migratory, diving bird of the family Podicipidæ. It has a duck-like body, brownish and white plumage, long neck, short wings, no tail, and large, flattened toes furnished with lobate membranes serving the purpose of webs. Most of its life is spent in fresh water  lakes and ponds, but in winter and during migration, it often resorts to the sea. It is an excellent diver. The nest is made of rushes and other aquatic plants and usually floats on the water, being loosely anchored to weeds and grass. It is found in nearly all parts of Europe and Asia.
