Cleft Bramble

The Cleft Bramble, Rubus laciniatus, known also as the Cutleaf or Evergreen Blackberry, is a vigorous, thorny shrub in the family Rosaceae native to central and southeastern Europe, from the Balkans through to southwestern Asia. It is widely naturalized in western North America, southern Australia, New Zealand, and other temperate regions where it was introduced as a garden plant or for erosion control. The distinctive deeply divided, laciniate leaves with finely cut leaflets distinguish it from other brambles. Like other Rubus species, it produces edible black fruits relished by birds and mammals, making it an important food plant for wildlife, but its vigorous growth and ability to root from stem tips make it an aggressive colonizer and a serious invasive species in many regions outside its native range. In the Pacific Northwest of the United States, Rubus laciniatus forms dense, impenetrable thickets that displace native vegetation and reduce biodiversity. Control is difficult given its extensive root system and the ability of fragments to regenerate. The species is listed as a noxious weed in several US states and Australian states. In its native European range, Cleft Bramble is not threatened and occurs in woodland edges, hedgerows, and scrubby habitats.

common sea hare

<em>Aplysia punctata</em>, the common sea hare, is a large opisthobranch sea slug in the family Aplysiidae, order Aplysiida, found in the northeastern Atlantic Ocean and Mediterranean Sea, with confirmed records from Denmark, Norway, Portugal, and Sweden. This species typically inhabits shallow subtidal and intertidal zones with abundant macroalgae, feeding primarily on red and green algae — a diet that influences the color of the defensive purple ink it secretes when threatened. <em>Aplysia punctata</em> is a simultaneous hermaphrodite, capable of acting as both male and female during mating, and often forms mating chains involving multiple individuals. It can reach considerable size among European opisthobranch species, though body dimensions vary considerably with age and feeding conditions. The species is classified as Least Concern by the IUCN, reflecting stable populations across its coastal range. Biological traits for this species remain poorly documented in the scientific literature, including precise average data on lifespan, body length, weight, and detailed seasonal dietary patterns, though its general herbivorous feeding on macroalgae is well established.
