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.

灰背舞雀

灰盐鸟是一种中大型健壮的鸟类，上体灰色，下体近白，具有被黑色髭纹镶边的醒目白喉，栖息于从墨西哥经中美洲至玻利维亚和阿根廷的广大分布区内的林缘、庭园和次生林地。适应性极强，在热带拉丁美洲各地的城郊公园和庭园中均能茁壮生长。它们发出丰富多变的悦耳鸣声，是受干扰的新热带景观中较为常见的大型鸣禽之一。
