Pinguicula alpina is hemicryptophytic, in that the plant survives the cold winter conditions by reducing to a bud resting on the soil surface. This bud, called a hibernaculum , is composed of small, densely packed leaves, which unfurl with the coming of spring.
The buds are pale brown, which readily distinguishes it from the related Fraxinus excelsior (black buds) even in winter. The leaves are in opposite pairs or whorls of three, pinnate, 15–25 cm long, with 3–13 leaflets; the leaflets being distinctively slender, 3–8 cm long and 1–1.5 cm broad.
The buds are a distinctive narrow conic shape, 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long, with red-brown bud scales. The leaves are spirally arranged but slightly twisted at the base to be upswept above the shoot, needle-like, 2–3 cm ( 3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, gray-green to blue-green above with a single broad stomatal patch, and with ...
Animals should be able to acclimate to decreasing temperatures as the seasons transition from fall to winter, but in cases of sudden and extreme weather changes, Sapp says owners may need to ...
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
All animals remain on-site throughout the year in their various homes. Jasmine, a snow leopard, alternates between indoor and outdoor areas along with Raj, the zoo's male snow leopard at Binder ...
Hibernaculum (plural hibernacula) is the term often applied to a winter bud of certain aquatic plants, such as the bladderworts (Utricularia). The buds are heavier than water, and, being developed at the approach of cold weather, they become detached, sink to the bottom of the pond, and thus survive the winter.
The offspring or new tubers are attached to a parent tuber or form at the end of a hypogeogenous (initiated below ground) rhizome. In the autumn the plant dies, except for the new offspring tubers, which have one dominant bud that in spring regrows a new shoot producing stems and leaves; in summer the tubers decay and new tubers begin to grow.
