Adiantum viridimontanum

Adiantum viridimontanum, the Green Mountain maidenhair fern, is a rare fern found in outcrops of serpentine rock in New England and Quebec. It is named after the site of its discovery in the Green Mountains in Vermont. Until 1991, it was grouped with the western maidenhair fern A. aleuticum, which itself was classified as a variety of the northern maidenhair fern A. pedatum. A. viridimontanum is a hybrid species and the other two ferns are distinct species, although it is difficult to distinguish between the three in the field. Due to the limited distribution of A. viridimontanum and its similarity to other species, little is known of its ecology. It thrives on sunny, disturbed areas where ultramafic rock is covered with thin soil, such as roadcuts, talus slopes, and asbestos mines. Individual plants seem long-lived, and new ones only infrequently reach maturity. One of four species endemic to serpentine in eastern North America, it is considered vulnerable due to its habitat restrictions. (Full article...)

Komodo dragon

The Komodo dragon (Varanus komodoensis), also known as the Komodo monitor, is a species of monitor lizard in the family Varanidae that is endemic to the Indonesian islands of Komodo, Rinca, Flores, and Gili Motang. It is the largest extant species of lizard, growing to a maximum length of 3 metres (10 ft), and weighing up to approximately 70 kilograms (150 lb). The Komodo dragon prefers hot and dry places, and typically lives in dry, open grassland, savanna, and tropical forest at low elevations. As an ectotherm, it is most active in the day, although it exhibits some nocturnal activity. Komodo dragons are solitary, coming together only to breed and eat. They are capable of running rapidly in brief sprints up to 20 km/h (12 mph), diving up to 4.5 metres (15 ft), and climbing trees proficiently when young through use of their strong claws. To catch out-of-reach prey, it may stand on its hind legs and use its tail as a support. As it matures, its claws are used primarily as weapons, as its great size makes climbing impractical. This photograph of two Komodo dragons fighting was taken on the island of Rinca, within Komodo National Park.
