Cogongrass

Cogongrass (Imperata cylindrica) is a perennial rhizomatous grass in the family Poaceae, widely regarded as one of the world's most invasive plant species, ranking among the top ten worst weeds globally due to its aggressive growth, fire adaptations, and competitive suppression of native vegetation. Native to the tropical and subtropical regions of Asia, Africa, and the Mediterranean, cogongrass has established invasive populations across the southeastern United States, parts of Latin America, and various Pacific islands. The grass forms dense, monospecific stands of erect, sword-like leaves with sharp white midribs, growing 60–120 centimetres tall and producing silky white plumes of wind-dispersed seeds. Its extensive underground rhizome network allows it to survive fire, drought, and cultivation disturbance that destroys competing species. Cogongrass dramatically alters fire regimes by producing large volumes of dry biomass that burn intensely and frequently, eliminating fire-sensitive native plants and preventing forest regeneration. Control is extremely challenging, requiring repeated applications of herbicides such as glyphosate and imazapyr combined with prescribed burning. Despite its invasive character outside its native range, cogongrass has traditional uses in Asia, including thatching, erosion control, and folk medicine. IUCN has not formally evaluated its conservation status.

지구상에서 가장 키가 큰 동물인 기린(Giraffa camelopardalis)은 키가 5.5m에 달하고 체중이 최대 1,750kg에 이를 수 있다. 모든 포유류와 같이 7개의 경추로 이루어진 긴 목은 아프리카 사바나와 산림의 아카시아 나무 먹이 섭취를 위해 진화했다. 영구적인 결속 없이 느슨한 무리를 이루며 생활하는 사회적 동물로, 초저주파음과 몸짓으로 소통한다. 서식지 상실과 밀렵으로 개체군이 감소하고 있는 취약 종이다.
