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.

Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。
