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.

Common Sawfly

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (4 countries) and North America (Canada, United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

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.

Common Sawfly

<em>Cladius grandis</em> is a sawfly in the family Tenthredinidae, with a Holarctic distribution spanning Europe and North America, documented from Canada, the United States, and multiple European countries. The species is primarily associated with rose family shrubs and trees, with larvae feeding externally on the leaves of cultivated and wild roses (<em>Rosa</em> spp.) as well as related plants. Larvae are pale green and slug-like in appearance, resembling the related rose slug sawfly larvae, and feed by skeletonizing leaves, stripping the upper epidermis and leaving a characteristic translucent "window" pattern that later turns brown. Infestations can cause cosmetic damage to cultivated roses and reduce the vigor of heavily attacked plants. Adults are small, black, wasp-like insects. The species is assessed as Near Threatened on the IUCN Red List, though the reasons for this designation and supporting population trend data specific to this species are not extensively documented in widely available sources. It typically produces multiple generations per year under favorable conditions in temperate climates. Pupation occurs in the soil, and overwintering takes place as prepupae or pupae. Biological traits such as average lifespan, body measurements, and comprehensive dietary data beyond host plant leaf tissue remain poorly documented in standardized ecological databases.
