Habitat & Geographic Range

Cockspur Vine

Habitat

Inhabits flooded grasslands and savannas within the Afrotropic biogeographic realm.

Range

Distributed across Brazil, Colombia, Mozambique, and Taiwan.

Foca común

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found across Europe (7 countries) and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Cockspur Vine

The cockspur vine (Pisonia aculeata) is a scrambling, often aggressively spiny liana or shrub in the family Nyctaginaceae — the four o'clock family — distributed pantropically in coastal and lowland thickets, forest edges, mangrove margins, and disturbed vegetation across the Americas, Africa, and Asia-Pacific, with documented occurrences in Brazil, Colombia, Mozambique, and Taiwan among many other countries. The plant is named for its hooked spines, which anchor it to neighbouring vegetation and enable it to climb and sprawl across host shrubs and trees, sometimes smothering them. Leaves are simple and opposite; flowers are small, inconspicuous, and unisexual, produced in branched clusters. The sticky fruits of the related genus Pisonia — particularly P. grandis and P. brunoniana — are notorious for entrapping and killing small seabirds in nesting colonies, but P. aculeata's fruits are less dramatically adhesive. The plant colonises disturbed coastal vegetation, roadsides, and secondary growth readily, and can become invasive in some regions outside its native range. It tolerates salt spray and is characteristic of coastal scrub and tropical dry forest ecotones. Some traditional uses have been recorded for leaf preparations. Pisonia aculeata is classified as Least Concern by the IUCN, reflecting its wide pantropical distribution and tolerance of disturbed habitats, though it is seldom abundant and its ecological role in intact native communities is that of a minor woody climber.

Foca común

El pinípedo de distribución más amplia, la foca común (Phoca vitulina) habita las costas templadas y subárticas del Atlántico Norte y el Pacífico Norte. Los adultos alcanzan hasta 130 kg y pasan aproximadamente el mismo tiempo en el mar cazando peces, calamares y crustáceos que descansando en playas y rocas. Sus grandes y expresivos ojos están adaptados para la visión subacuática en condiciones de poca luz. La foca común es una fuente de alimento fundamental para orcas, tiburones y osos polares.
