Compact Grimmia

<em>Schistidium confertum</em>, commonly known as compact grimmia, is a small cushion-forming moss in the family Grimmiaceae. It belongs to a genus of rock-dwelling mosses widely distributed across cool temperate and boreal regions of the Northern Hemisphere. This species has been recorded from Luxembourg, Norway, Sweden, and the United States, typically colonising exposed siliceous and calcareous rock surfaces in open or lightly shaded environments. Compact grimmia typically forms dense, compact tufts or cushions closely adhering to rock faces, providing stability and retaining moisture in harsh, exposed habitats. Like other Schistidium mosses, it is adapted to periodic desiccation, able to survive extended dry periods and rehydrate rapidly when moisture returns. The species contributes to the ecological community of rock surface microhabitats, creating substrate for other microorganisms and serving as a component of biological soil and rock crusts. It is classified as Vulnerable by the IUCN in parts of its range, reflecting sensitivity to air pollution, acid deposition, and habitat disturbance, particularly in northwestern Europe where many moss species have declined. Biological traits including specific growth rates, reproductive biology, and detailed ecological requirements remain poorly documented compared to more widely studied bryophyte species. Conservation of compact grimmia depends on maintaining clean air quality and protecting undisturbed rock habitats from quarrying and recreational disturbance.

Guacamaya roja

Una de las aves mas vistosamente coloreadas de las Americas, la guacamaya roja (Ara macao) exhibe un brillante plumaje rojo, amarillo y azul con una envergadura de hasta 1 metro. Habita en bosques humedos de tierras bajas desde Mexico hasta Bolivia; es muy inteligente, longeva -hasta 75 anos- y forma parejas de por vida. Viaja largas distancias hasta saladeros donde consume suelo rico en minerales para desintoxicar semillas. Clasificada como Preocupacion Menor, aunque localmente amenazada por la perdida de habitat y el comercio de mascotas.
