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.

Common Sunda Toad

<em>Duttaphrynus melanostictus</em>, the common Sunda toad, is an amphibian in the family Bufonidae, order Anura. It has a wide natural distribution across South and Southeast Asia, ranging from Pakistan and India through to southern China, the Malay Peninsula, and the Indonesian archipelago, and has also been introduced to Madagascar. The species typically inhabits a broad range of environments including urban areas, agricultural land, forest edges, gardens, and disturbed habitats, demonstrating remarkable adaptability to human-modified landscapes. <em>Duttaphrynus melanostictus</em> is characterized by prominent parotoid glands behind the eyes that secrete toxic compounds serving as a defense against predators, a feature shared with other true toads. It is an opportunistic carnivore, feeding on a variety of invertebrates including insects, worms, and small arthropods. Biological traits including average lifespan under natural conditions, typical body measurements, and specific breeding parameters remain poorly documented. The species is assessed as Least Concern by the IUCN, reflecting its extensive range and high tolerance for habitat modification, though introduced populations in Madagascar represent a potentially invasive concern.
