Range

Distributed across Ecuador and Norway.

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.

Common Cactus-Finch

<em>Geospiza scandens</em>, commonly known as the common cactus finch, is a bird species found in Ecuador and with records from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often closely associated with arid island ecosystems where cacti are prevalent. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. The common cactus finch belongs to the genus <em>Geospiza</em> within the family Thraupidae and is among the iconic Darwin's finches of the Galápagos Islands. It typically feeds on the nectar, pollen, and seeds of cactus plants, particularly <em>Opuntia</em>, and plays an important role as a pollinator and seed disperser within its island habitat. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Population trends are considered stable, and the species remains an important subject of evolutionary and ecological research.

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.
