Clustered Stonewort

Tolypella glomerata, the clustered stonewort, is a charophyte alga in the family Characeae, found in calcareous, nutrient-poor freshwater habitats including lakes, ponds, ditches, and slow-flowing water in northwestern and northern Europe. Charophytes are macroscopic green algae with a distinctive whorl-like arrangement of branches and a complex, plant-like structure that distinguishes them from other algae. T. glomerata is encrusted with calcium carbonate deposits (hence 'stonewort'), giving it a pale, grey-green appearance and rough texture. The species colonizes clear, low-nutrient water over fine sediment or gravel substrates where competition from vascular plants is reduced by nutrient limitation. It is listed as Vulnerable by the IUCN, reflecting significant declines driven by eutrophication (nutrient enrichment from agriculture and sewage), which promotes the growth of vascular plants and phytoplankton that shade out stoneworts. Drainage, water abstraction, and peat cutting also threaten its habitats. Charophyte diversity has declined substantially across lowland Europe and North America over the past century, with many species becoming locally extinct from sites they once colonized.

Common Tent-making Bat

<em>Uroderma bilobatum</em>, the tent-making bat, is a leaf-nosed bat in the family Phyllostomidae, distributed across Central America and northern South America, including Colombia, Ecuador, and Venezuela. It is classified as Least Concern on the IUCN Red List due to its wide range and tolerance of secondary and disturbed habitats. This bat is named for its remarkable behavior of biting through the midribs of large palm or Heliconia leaves to cause them to fold into tent-like roosts, which are used for shelter by small colonies. It typically inhabits tropical and subtropical lowland forests, forest edges, and plantations. The diet consists primarily of fruits, particularly figs, making it an important seed disperser in neotropical ecosystems. Roosting groups are typically small, composed of one male and several females. The species uses echolocation for navigation. Biological traits such as precise wing dimensions, body weight, and longevity remain poorly documented in standardized assessments, though adults typically weigh between 13 and 20 grams.
