African elephant

O elefante africano, o maior animal terrestre da Terra, pode atingir 7.000 kg e habita savanas, florestas e zonas húmidas da África subsaariana. Com estruturas sociais complexas lideradas por matriarcas, comunica através de infrassons, rugidos e contacto físico. Como engenheiro do ecossistema, modela o habitat arrancando árvores, escavando poços de água e dispersando sementes. Está classificado como Vulnerável (VU), com populações em declínio devido à caça furtiva de marfim e à perda de habitat.

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.
