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 Bladder Moss

The common bladder moss (<em>Physcomitrium pyriforme</em>) is a small annual moss belonging to the family Funariaceae. It is classified as Least Concern on the IUCN Red List and is native to Europe and North America, with confirmed records from Luxembourg, Portugal, and the United States. <em>Physcomitrium pyriforme</em> typically colonizes disturbed, moist soils such as cultivated fields, riverbanks, and pond margins, where it forms low-growing green mats or cushions. The species is an ephemeral moss, completing its life cycle rapidly after disturbance events that expose bare soil. It is recognizable by its pear-shaped or inflated capsules borne on short setae, which give the species its common name. Spores are dispersed through the splitting of the capsule lid, and the plant often takes advantage of temporarily wet conditions for growth and reproduction. Biological traits of this species remain poorly documented in the scientific literature.
