Habitat & Geographic Range

Club Grain-Spored Lichen

Habitat

Native to Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Denmark, Norway, Sweden, and United States.

gray wolf

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Club Grain-Spored Lichen

Sarcogyne clavus is a crustose lichen in the family Acarosporaceae, forming closely appressed, granular to warty grey-white thalli on calcareous rocks, concrete, mortar, and exposed mineral substrates. The species is characterized by its distinctive club-shaped or clavate ascospores, from which its specific name derives. Like other Sarcogyne species, it produces apothecia that are typically lecideine (lacking a thalline margin), dark-colored, and often somewhat convex. This lichen favors exposed, sunny rock faces with high calcium content, including limestone outcrops, old walls, and stone monuments. S. clavus is distributed across Europe and North America, occurring primarily in calcareous rock habitats. As a pioneer colonizer of bare rock, it contributes to the initial stages of ecological succession by weathering the substrate and accumulating organic matter. The IUCN lists this species as Data Deficient, reflecting insufficient data on its population size, distribution, and ecology to assess its conservation status with confidence. Lichens as a group are sensitive to air pollution, but calcicolous crustose lichens on exposed rock may be less vulnerable than foliose or fruticose species.

gray wolf

The most widely distributed wild canid, gray wolves range from North America across Eurasia in diverse habitats including tundra, forests, and grasslands. Highly social animals living in family packs led by a dominant breeding pair. As keystone predators, wolves regulate prey populations and profoundly shape ecosystem structure, as demonstrated by their reintroduction in Yellowstone. Once heavily persecuted, populations are recovering in many regions.
