Coastal Bastard Toad-flax

Thesium maritimum, the coastal bastard toad-flax, is a semi-parasitic herbaceous plant in the family Santalaceae native to coastal sand dunes, calcareous grassland, and scrubland along the northern Mediterranean coast of Europe, extending through the Iberian Peninsula and into parts of southwestern France. Like other members of the genus Thesium, it is a hemiparasite, maintaining chlorophyll and photosynthesizing while simultaneously tapping the root systems of neighboring grasses and herbs to extract water and nutrients through haustorial connections. The species produces small, narrow leaves and inconspicuous white to cream flowers typical of the family, lacking showy petals and relying on insect visitors for pollination. Thesium maritimum is classified as Vulnerable by the IUCN, reflecting significant population declines associated with loss and degradation of its specialized coastal habitat through tourist infrastructure development, coastal stabilization, invasive species encroachment, and sand dune fixation. Mediterranean coastal sand dune systems across Europe have been extensively modified, and the open, dynamic habitats required by this specialist species have contracted substantially over recent decades. Conservation measures include dune restoration, reduction of vehicle traffic on coastal habitats, and control of invasive species that fix and stabilize natural shifting sands.

Lion

アフリカ最大の野生ネコ科動物で最大250kgに達し、サハラ以南のサバンナや草原に生息する唯一の社会性ネコ科動物です。雄は象徴的なたてがみで識別されます。頂点捕食者として草食動物の個体群を調節し、生態系のバランスを維持します。生息地の喪失と人間との軋轢により危急種に分類されています。
