common freshwater amphipod

<em>Gammarus pulex</em> is a small crustacean in the family Gammaridae, order Amphipoda, commonly known as the common freshwater amphipod or freshwater shrimp. This species inhabits freshwater streams, rivers, and lakes across Europe, with documented occurrences in six European countries. <em>Gammarus pulex</em> is a key component of freshwater ecosystems, serving as an important detritivore and shredder that breaks down leaf litter and organic matter, contributing significantly to nutrient cycling in stream ecosystems. It also forms a critical prey item for freshwater fish, birds, and invertebrate predators, occupying a central position in freshwater food webs. The species is highly sensitive to water quality, particularly to organic pollution and chemical contaminants, and is frequently used as a bioindicator in freshwater ecological assessments. <em>Gammarus pulex</em> typically inhabits cool, well-oxygenated running waters with abundant leaf litter and debris. Biological traits of this species remain poorly documented in the scientific literature.

Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
