Cliff Scalewort

Cliff Scalewort, Porella obtusata, is a leafy liverwort in the family Porellaceae found on cliff faces, shaded rock surfaces, and the bark of trees in moist, humid environments across Europe and North America. Porella is one of the most diverse and widely distributed leafy liverwort genera, with species adapted to a range of substrates from bark and rock to soil in forests and coastal habitats. Cliff Scalewort forms flat, overlapping mats of small, scale-like leaves arranged in two lateral rows and a row of smaller underleaves, creating a texture that gives the plant its common name. The green to brownish-green plants are tightly appressed to the surface, extracting moisture from rainfall and condensation. Liverworts in this family reproduce sexually when conditions are favorable, producing small capsules on delicate setae, as well as vegetatively through fragmentation. Porella species on cliff faces are sensitive to air pollution, particularly sulfur dioxide, and have declined in many industrial regions of Europe, recovering more recently as air quality has improved. They serve as indicators of habitat continuity and air quality in ecological assessments. Cliff Scalewort is not globally threatened but may be locally rare in heavily polluted or drought-prone areas.

Gorila Occidental

El primate más grande del mundo, los gorilas occidentales pesan hasta 180 kg y habitan los bosques tropicales y subtropicales del África ecuatorial. Principalmente herbívoros, viven en grupos familiares liderados por un macho de espalda plateada que protege la tropa y media en los conflictos sociales. En Peligro Crítico, con poblaciones amenazadas por la deforestación, la caza furtiva para la venta de carne de monte y los brotes del virus del Ébola.
