Coastal beach sandmat

Euphorbia mesembryanthemifolia, the coastal beach sandmat, is a prostrate, mat-forming succulent herb in the family Euphorbiaceae adapted to coastal sand dune and beach margins in the Caribbean basin, with native occurrences in Cuba, Colombia, and adjacent tropical American coastlines. The species is particularly well adapted to harsh coastal conditions including salt spray, intense solar radiation, shifting sands, and periodic flooding, forming low, spreading mats directly on beach sand and foredune systems. Its small, thick, succulent leaves resemble those of ice plants (Mesembryanthemum) in the family Aizoaceae, a resemblance captured in the specific epithet. Like all euphorbias, it contains a toxic milky latex that deters herbivory. The cyathia, or characteristic euphorbia pseudoflowers, attract small insects that pollinate the plants. Euphorbia mesembryanthemifolia is classified as Least Concern by the IUCN, though Caribbean coastal habitats face significant ongoing threats from sea-level rise, increased storm surge associated with intensifying hurricanes, beach tourism infrastructure development, and coastal stabilization that removes the natural dynamism these specialist plants require to persist and disperse along shorelines.

ours blanc

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
