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.

コウカンチョウ

アカボウシインコチョウ（Paroaria coronata）はボリビア・ブラジルからアルゼンチンにかけての南アメリカ原産の、鮮やかな赤い冠羽、白い顔、灰色の体を持つ目を引く中型鳥類で、ハワイや太平洋の島々に移入されてホノルルの象徴的な庭鳥となった。密な低木、草地の端、郊外の庭に生息し、種子や小型昆虫を採食する。その名前や外見の類似性にもかかわらず、北米のショウジョウコウカンチョウとは近縁ではなく、フウキンチョウ科に属する。
