Rivinis Veilchen

<em>Viola riviniana</em>, the common dog-violet, is a perennial herbaceous plant in the family Violaceae. This species is widely distributed across Europe, including records from seven European countries, as well as Canada and Australia, where it occupies diverse terrestrial habitats such as woodlands, hedgerows, grasslands, and moorlands. The common dog-violet is characterized by its heart-shaped leaves and violet-blue, spurred flowers that typically bloom from spring through early summer. Unlike many violets, its flowers are unscented. <em>Viola riviniana</em> often spreads both by seed and vegetatively via rhizomes, forming patches in suitable habitats. This species is an important larval food plant for several fritillary butterfly species, making it ecologically significant for butterfly conservation in Britain and Europe. It generally favors well-drained, slightly acidic soils in partially shaded environments. The common dog-violet is assessed as Least Concern, with stable populations across most of its range. Its adaptation to a variety of woodland and grassland habitats contributes to its widespread occurrence.

Acker-Schmalwand

<em>Arabidopsis thaliana</em>, commonly known as common wall cress or thale cress, is a small annual flowering plant in the family Brassicaceae native to Eurasia and Africa, and now naturalized in North America, Australia, and other temperate regions worldwide. The species has become one of the most important model organisms in plant biology and genetics, owing to its small genome size, short generation time of approximately six weeks, prolific seed production, and ease of laboratory cultivation. <em>Arabidopsis thaliana</em> was the first plant to have its complete genome sequenced, in 2000, revolutionizing our understanding of plant molecular biology, development, and physiology. In nature, it typically grows in rocky outcrops, disturbed sandy soils, walls, roadsides, and waste ground, tolerating poor nutrient conditions and a wide range of climates. The plant produces a basal rosette of small ovate leaves, followed by an erect flowering stem bearing tiny white four-petaled flowers and slender silique seed pods. Despite its modest appearance, <em>Arabidopsis thaliana</em> has facilitated thousands of scientific discoveries in plant genetics, epigenetics, and stress responses. The species is currently assessed as Least Concern by the IUCN. Biological traits such as average lifespan, plant height up to 30 centimeters, and seed output are well-characterized in laboratory settings.
