Common Spike-thorn

<em>Gymnosporia buxifolia</em>, commonly known as the common spike-thorn, is a spiny shrub or small tree in the family Celastraceae, native to sub-Saharan Africa. This species typically inhabits a variety of vegetation types including bushveld, riverine thickets, rocky hillsides, forest margins, and disturbed areas, demonstrating considerable ecological versatility. It is widely distributed across eastern and southern Africa, with populations recorded in countries including South Africa, Zimbabwe, Mozambique, Tanzania, and Kenya, among others in the region. Classified as Least Concern on the IUCN Red List, <em>Gymnosporia buxifolia</em> is considered stable throughout much of its range. The plant is characterised by its stout axillary thorns, small dark green leaves, and small white to cream flowers followed by three-lobed capsular fruits. It plays an ecological role as a host plant for various insects and as a food source for browsing mammals. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The species is also used in traditional medicine across parts of its range, and its dense thorny growth makes it useful as a natural hedge or barrier plant in agricultural and homestead settings.

pinguim-imperador

O maior pinguim do mundo, os pinguins-imperadores medem até 1,2 metro de altura e pesam 45 kg, habitando o continente antártico em algumas das condições mais extremas da Terra. Reproduzem-se no meio do inverno, na escuridão, a temperaturas abaixo de -60°C, com os machos incubando ovos únicos sobre os pés sob uma bolsa de criação por 65 dias enquanto as fêmeas estão no mar. Seu comportamento de aglomeração — onde os indivíduos revezam-se pelo centro quente de grupos de milhares — é uma obra-prima de sobrevivência cooperativa.
