Cockspur Vine

The cockspur vine (Pisonia aculeata) is a scrambling, often aggressively spiny liana or shrub in the family Nyctaginaceae — the four o'clock family — distributed pantropically in coastal and lowland thickets, forest edges, mangrove margins, and disturbed vegetation across the Americas, Africa, and Asia-Pacific, with documented occurrences in Brazil, Colombia, Mozambique, and Taiwan among many other countries. The plant is named for its hooked spines, which anchor it to neighbouring vegetation and enable it to climb and sprawl across host shrubs and trees, sometimes smothering them. Leaves are simple and opposite; flowers are small, inconspicuous, and unisexual, produced in branched clusters. The sticky fruits of the related genus Pisonia — particularly P. grandis and P. brunoniana — are notorious for entrapping and killing small seabirds in nesting colonies, but P. aculeata's fruits are less dramatically adhesive. The plant colonises disturbed coastal vegetation, roadsides, and secondary growth readily, and can become invasive in some regions outside its native range. It tolerates salt spray and is characteristic of coastal scrub and tropical dry forest ecotones. Some traditional uses have been recorded for leaf preparations. Pisonia aculeata is classified as Least Concern by the IUCN, reflecting its wide pantropical distribution and tolerance of disturbed habitats, though it is seldom abundant and its ecological role in intact native communities is that of a minor woody climber.

Common Neacomys

<em>Neacomys spinosus</em>, the common neacomys or spiny neacomys, is a small rodent in the family Cricetidae found in South America. This ground-dwelling mouse is characterized by its distinctively spiny fur, an adaptation that may provide protection against predators. <em>Neacomys spinosus</em> typically inhabits tropical lowland and montane forests, forest edges, and adjacent scrubby vegetation in northwestern South America, with its geographic range including Colombia and surrounding countries. The species forages on the forest floor and in low vegetation, and is believed to consume seeds, plant material, and invertebrates, although specific dietary data are limited. It is currently assessed as Least Concern by the IUCN, with populations considered stable across its range, though ongoing deforestation in the Amazonian and Andean foothills may present long-term threats. Biological traits such as lifespan, body size, and diet remain poorly documented for this species across its full range. <em>Neacomys spinosus</em> plays a role in seed dispersal and forms part of the prey base for small mammalian and avian predators in its tropical forest ecosystems.
