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.

Cocconeis neodiminuta is a small, adnate diatom in the family Cocconeidaceae, distinguished from related species within the genus by its diminutive frustule size and specific silica wall ornamentation patterns resolvable by electron microscopy. As a member of the genus Cocconeis, this species is an epiphytic organism that lives attached to the surfaces of aquatic plants, filamentous algae, sediment particles, and submerged solid substrates in freshwater and occasionally brackish environments. The frustule—the intricate silica cell wall that encases the diatom cell—consists of two overlapping halves (valves) with species-specific striation patterns and pore fields (areolae) used in taxonomic identification. Cocconeis neodiminuta has been documented from freshwater environments across South America and various other regions, suggesting a broad cosmopolitan distribution consistent with many freshwater diatom taxa. The species, like other cocconeid diatoms, reproduces primarily by asexual binary fission, with periodic sexual reproduction through auxospore formation to restore cell size after successive divisions cause progressive size reduction. As a photosynthetic primary producer in benthic communities, this diatom contributes to the base of aquatic food webs and participates in the biological cycling of silicon—an element critical to diatom frustule production and removed from solution as diatoms proliferate. Its conservation status has not been evaluated by the IUCN.

gray wolf

O lobo-cinzento (Canis lupus), o canídeo selvagem mais amplamente distribuído, ocorre da América do Norte à Eurásia em habitats diversos, incluindo tundra, florestas e pradarias. São animais altamente sociais que vivem em matilhas familiares lideradas por um casal reprodutor dominante. Como predadores-chave, os lobos regulam as populações de presas e moldam profundamente a estrutura do ecossistema, como demonstrou sua reintrodução em Yellowstone. Antes muito perseguidos, as populações estão se recuperando em muitas regiões.
