Habitat & Geographic Range

Common Water Clover

Habitat

Typically found in moist, shaded forest floors and tropical canopies.

Range

Widely distributed across Asia (India, Vietnam), Europe (5 countries), and North America (Canada, United States).

Lion

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 7 distinct biome types spanning the Afrotropic and Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia, Ecuador, and Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Water Clover

<em>Marsilea quadrifolia</em>, commonly known as the common water clover or European waterclover, is an aquatic fern in the family Marsileaceae. Its conservation status is listed as Not Evaluated by the IUCN. The species has a broad native distribution spanning Asia and Europe, and has been introduced to North America, where it now occurs in scattered freshwater habitats. It typically grows in shallow ponds, rice paddies, slow-moving streams, and muddy lake margins, rooting in soft sediments while its four-leaflet fronds float on or emerge above the water surface. The distinctive four-lobed leaves strongly resemble a four-leaf clover, lending the plant its common name. <em>Marsilea quadrifolia</em> is a heterosporous fern, producing specialized reproductive structures called sporocarps that contain both megaspores and microspores, allowing reproduction under conditions unfavorable for vegetative growth. The plant is remarkably drought-tolerant, as sporocarps can remain viable for decades. It typically spreads through both vegetative rhizome growth and spore dispersal. Biological traits including average lifespan, height, and mass remain poorly documented in standardized databases. The species plays a role in shallow aquatic ecosystems as a colonizing plant, stabilizing soft substrates and providing microhabitat for invertebrates and small vertebrates in the temperate freshwater zones it inhabits.

Lion

The largest wild cat in Africa, lions reach up to 250 kg and are the only social felids, living in prides across sub-Saharan savannas and grasslands. Males are distinguished by their iconic manes. As apex predators, they regulate herbivore populations and maintain ecosystem balance. Listed as Vulnerable due to habitat loss and human-wildlife conflict.
