Clusterspike False Indigo

Amorpha crenulata, known as clusterspike false indigo or crenulate lead plant, is a critically endangered flowering shrub in the family Fabaceae with a highly restricted distribution confined to Miami-Dade County in southern Florida, USA. This species represents one of North America's rarest plants, with remaining populations numbering in the hundreds of individuals occurring in pine rockland habitat, an ecosystem itself ranked among the most imperiled in the United States. Pine rocklands are fire-dependent communities on exposed oolitic limestone, characterized by an open canopy of slash pine over diverse understory, and have been reduced to less than two percent of their historical extent by urban development in the Miami metropolitan area. Amorpha crenulata produces elongated spikes of small purple flowers typical of the genus and was historically more widespread across the Miami Rock Ridge before land development eliminated most habitat. Current populations exist primarily within Everglades National Park and a few private preserves. Its Critically Endangered status reflects the tiny remaining population, extreme habitat restriction, ongoing threats from urbanization, altered fire regimes, and sea-level rise that threatens low-elevation limestone habitats. Conservation efforts focus on habitat protection, controlled burning to maintain pine rockland structure, and ex situ seed banking.

Long-tailed Sylph

긴꼬리실프(Aglaiocercus kingii)는 가장 화려하게 장식된 벌새 중 하나로, 수컷은 금속빛 녹색 깃털과 22cm에 달하는 리본 모양의 길게 늘어난 바깥 꼬리 깃털을 가지며 이는 몸 길이의 세 배를 넘는다. 콜롬비아와 베네수엘라의 안데스 구름 숲 해발 1,400~2,800m에 서식하며, 수컷은 암컷을 유혹하기 위해 정교한 과시 비행을 수행한다. 화려한 꼬리는 암컷의 선택에 의한 성적 선택의 고전적인 사례다.
