Range

Distributed across Brazil 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.

Clay-Gilled Milkcap

The Clay-gilled Milkcap, Lactarius helvus, is a medium to large mushroom in the family Russulaceae, notable for its distinctive fenugreek-like or curry-like scent when fresh or dried. The cap is typically dry, pale buff to pale brick-brown, and convex becoming flat or centrally depressed with age. The gills are closely spaced, crowded, and pale clay to buff in color, giving rise to the common name. When cut or broken, the flesh exudes a watery, mild to faintly acrid white latex, characteristic of the genus Lactarius. The Clay-gilled Milkcap is ectomycorrhizal, forming associations primarily with spruce and pine in boreal and montane forests of Europe, North America, and northern Asia. It fruits from late summer through autumn in coniferous forests, often in large numbers following rainy periods. Although widely consumed in parts of Eastern Europe after prolonged boiling and processing, the raw mushroom contains sesquiterpene lactones that can cause gastrointestinal distress and is considered mildly toxic if eaten without preparation. Its dried form is used as a spice substitute in some traditional recipes due to its aromatic qualities. The species is widespread and not considered threatened within its boreal and montane conifer forest range.

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.
