Habitat & Geographic Range

Buckelwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Dichtes Spalthütchenmoos

Habitat

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

Range

Distributed across Luxembourg, Norway, Sweden, and United States. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Dichtes Spalthütchenmoos

<em>Schistidium confertum</em>, commonly known as compact grimmia, is a small cushion-forming moss in the family Grimmiaceae. It belongs to a genus of rock-dwelling mosses widely distributed across cool temperate and boreal regions of the Northern Hemisphere. This species has been recorded from Luxembourg, Norway, Sweden, and the United States, typically colonising exposed siliceous and calcareous rock surfaces in open or lightly shaded environments. Compact grimmia typically forms dense, compact tufts or cushions closely adhering to rock faces, providing stability and retaining moisture in harsh, exposed habitats. Like other Schistidium mosses, it is adapted to periodic desiccation, able to survive extended dry periods and rehydrate rapidly when moisture returns. The species contributes to the ecological community of rock surface microhabitats, creating substrate for other microorganisms and serving as a component of biological soil and rock crusts. It is classified as Vulnerable by the IUCN in parts of its range, reflecting sensitivity to air pollution, acid deposition, and habitat disturbance, particularly in northwestern Europe where many moss species have declined. Biological traits including specific growth rates, reproductive biology, and detailed ecological requirements remain poorly documented compared to more widely studied bryophyte species. Conservation of compact grimmia depends on maintaining clean air quality and protecting undisturbed rock habitats from quarrying and recreational disturbance.
