Coastal Rocket Frog

Coastal rocket frog (Allobates bromelicola) is a small terrestrial frog in the family Allophrynidae (formerly placed in Dendrobatidae), endemic to coastal lowland forests of Venezuela. Despite its placement near poison dart frogs, Allobates species are non-toxic. This species inhabits the humid leaf litter and bromeliads of coastal Venezuelan forests, where adults care for egg clutches and transport tadpoles to small water bodies including bromeliad phytotelmata. The genus Allobates is widespread across Amazonian and coastal South American forests, characterised by vocal males, ground-level activity, and close parental care. Coastal rocket frog is assessed as Vulnerable by the IUCN, primarily due to restricted range, habitat loss from deforestation for agriculture, livestock grazing, and urban expansion along Venezuela's coast. Climate change poses an additional threat through altered precipitation patterns affecting its bromeliad microhabitats. The species' specific association with bromeliads makes it particularly sensitive to vegetation structure loss. As with many narrowly endemic amphibians, ex-situ conservation programmes and improved habitat protection within its range are considered important management priorities.

Common Tule

<em>Schoenoplectus acutus</em>, commonly known as common tule or hardstem bulrush, is a tall emergent aquatic plant in the family Cyperaceae native to wetlands across North America, particularly abundant in the western United States and Canada. It is a dominant species in freshwater marshes, lake margins, river edges, and tidal wetlands, forming extensive stands that provide critical habitat and ecosystem services. The stems are stiff, sharply triangular in cross-section, and can reach heights of up to 3 meters, with inflorescences of reddish-brown spikelets emerging near the tips. <em>Schoenoplectus acutus</em> typically grows in standing or slow-moving water up to 1 meter deep and is highly tolerant of fluctuating water levels. This species played a fundamental cultural role for many Indigenous peoples of western North America, who used the stems for basketry, boat construction, and thatching. Ecologically, tule marshes provide nesting habitat for numerous bird species, shelter for fish and invertebrates, and serve as important carbon sinks. The species is currently assessed as Least Concern by the IUCN. Its widespread distribution and abundance ensure population stability, though localized wetland loss remains a concern in many areas. Biological traits such as average plant lifespan, stem dimensions, and above-ground biomass are well-studied in ecological contexts but individual-level weight measurements remain poorly documented.
