Elefante de Sabana

El elefante africano, el animal terrestre más grande de la Tierra, puede alcanzar 7.000 kg y habita sabanas, bosques y humedales del África subsahariana. Con estructuras sociales complejas lideradas por matriarcas, se comunica mediante infrasonidos, rugidos y contacto físico. Como ingeniero del ecosistema, modela su hábitat arrancando árboles, excavando aguadas y dispersando semillas. Está catalogado como Vulnerable, con poblaciones en declive por la caza furtiva de marfil y la pérdida de hábitat.

common pygmy woodlouse

The Common Pygmy Woodlouse, <em>Trichoniscus pusillus</em>, is a small terrestrial isopod crustacean in the family Trichoniscidae, widely distributed across Europe and introduced to North America, with records from Denmark, Norway, Portugal, Sweden, and the United States. It is one of the most abundant and widespread woodlice in temperate regions, typically found in moist, dark microhabitats including under stones, logs, leaf litter, bark, and in soil crevices in gardens, woodlands, and grasslands. <em>Trichoniscus pusillus</em> is a very small species, measuring only a few millimeters in length, with a reddish-brown to pale pink coloration and a smooth, slightly convex body. Unlike many larger woodlice, it does not roll into a ball when disturbed. The species plays an important role in decomposition and nutrient cycling, fragmenting decaying plant material and facilitating microbial breakdown. It is parthenogenetic in many parts of its range, with all-female populations reproducing without males. The species is assessed as Least Concern on the IUCN Red List given its abundance and widespread distribution. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
