Grasfrosch

<em>Rana temporaria</em>, commonly known as the common frog, is an amphibian in the family Ranidae and one of the most widespread frog species in Europe. It has been documented in Austria, Belgium, Czech Republic, Denmark, France, Germany, Latvia, and Norway, and its range extends broadly across temperate Europe and parts of Asia. <em>Rana temporaria</em> typically inhabits a variety of environments including freshwater bodies, forests, grasslands, wetlands, and human-modified landscapes, demonstrating considerable ecological flexibility. It is assessed as Least Concern, supported by its extensive distribution and generally stable population trends across most of its range. The common frog is a key component of many European ecosystems, playing important roles both as a predator of invertebrates and as prey for a range of birds, mammals, and reptiles. It typically breeds in ponds and slow-moving water bodies in early spring. Biological traits of this species remain poorly documented in the scientific literature. Its sensitivity to habitat degradation and water quality makes it an important indicator species for freshwater and terrestrial ecosystem health.
