Comb-toed Jerboa

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Cliostomum corrugatum is a crustose lichen in the family Ramalinaceae, notable for producing characteristically wrinkled or corrugated apothecia that distinguish it from related taxa. The genus Cliostomum is a small group of saxicolous and corticolous crustose lichens with a disjunct distribution in temperate and boreal regions of the Northern Hemisphere, including Europe and North America. The thallus of Cliostomum corrugatum is thin and pale, often nearly immersed in the bark substrate on which it grows, while the pale tan to cream apothecia are flat to slightly convex with the distinctive corrugated or rugose surface. The species is found on the bark of deciduous trees in old, undisturbed woodland, including veteran oaks, beeches, and other broadleaved trees with stable, relatively unpolluted bark chemistry. Cliostomum species are considered indicators of ecological continuity in woodland habitats and are included in lists of ancient woodland indicator species in northwestern Europe. The species is sensitive to air pollution, particularly sulfur dioxide and nitrogen compounds from agricultural and industrial sources, and declined significantly across industrialized regions of Britain and Europe during the 20th century. Recovery has been noted in areas where air quality has improved. The species is of conservation concern in several European countries.

Comb-toed Jerboa

<em>Paradipus ctenodactylus</em>, the comb-toed jerboa, is a small nocturnal rodent in the family Dipodidae, assessed as Least Concern on the IUCN Red List. It is adapted to arid desert and semi-desert environments and is the sole member of the genus <em>Paradipus</em>. The species is named for the distinctive comb-like fringe of stiff hairs on the toes of the hind feet, which provides traction on loose sand surfaces. Like other jerboas, it is highly specialized for bipedal locomotion, possessing greatly elongated hind limbs relative to its body size, a long tail used for balance, and large ears. <em>P. ctenodactylus</em> is primarily granivorous and insectivorous, foraging for seeds, plant material, and invertebrates in its desert habitat. It digs burrows for shelter and protection from temperature extremes. Geographic range details are not recorded in the current record.
