Cliff Mining Bee

The Cliff Mining Bee, Andrena species in the family Andrenidae, is a solitary ground-nesting bee that excavates tunnels in cliff faces, earthen banks, and compacted sandy or loamy soils, where the loose or friable substrates exposed in cliff profiles provide ideal nesting conditions. Mining bees in the genus Andrena are among the most species-rich solitary bee genera in the world, with hundreds of species across the Holarctic region, many narrowly specialized in their choice of pollen host plants. Female cliff mining bees construct vertical or angled burrows in cliff faces, with lateral cells off the main shaft, each containing a pollen ball and a single egg. Males are typically smaller and emerge before females to establish territories near nesting sites. Many Andrena species are oligolectic, collecting pollen from only a small number of plant species, making their populations sensitive to the availability of specific flowering plants in the landscape surrounding nesting areas. Cliff and bank nesting habitats provide well-drained, sun-warmed substrates essential for brood development. The loss of natural cliff faces and earthen banks to development, vegetation succession, and quarrying reduces available nesting habitat for cliff mining bees.

Cokerite Palm

The Cokerite Palm (Attalea maripa), also known as Maripa Palm or Inajá, is a solitary, tall-growing feather palm in the family Arecaceae, distributed across the lowland rainforests, forest edges, and floodplain forests of Amazonian South America, primarily in Brazil and Colombia, with additional records from Venezuela, Guyana, Suriname, French Guiana, Peru, Bolivia, and Ecuador. Trees typically reach 15–25 metres in height, producing large pinnate fronds and impressive clusters of ovoid fruits with an oily, yellow-orange outer mesocarp surrounding a hard-shelled nut. The palm is widely used by indigenous and traditional communities throughout Amazonia: the oil-rich mesocarp of the fruits is eaten fresh and used to produce a nutritious food paste; the apical bud (palm heart) is consumed; the young leaves are used for basket weaving and thatching; and the trunk wood serves in construction. Attalea maripa frequently regenerates vigorously in disturbed forest and pasture margins, indicating tolerance for light disturbance. It plays an important ecological role as a food source for large frugivores including tapirs, peccaries, and macaws that help disperse its large seeds. The species is assessed as Least Concern by the IUCN, with stable populations across its broad Amazonian range.
