Climbing Flat-bean

Climbing Flat Bean, Vigna unguiculata subsp. sesquipedalis, commonly known as the Yard-long Bean or Asparagus Bean, is a vigorous climbing legume in the family Fabaceae widely cultivated across tropical and subtropical Asia for its extraordinarily long, edible pods. The pods, reaching up to 60–100 cm in length, are harvested when young and tender and are used extensively in Chinese, Southeast Asian, and South Asian cuisine. The species climbs trellises and poles using tendril-like, twining stems, producing purplish-white flowers that develop into the characteristic pendulous, slender bean pods. Like other Vigna species, it fixes atmospheric nitrogen through symbiotic bacteria in root nodules, improving soil fertility. Climbing Flat Bean is a warm-season crop requiring full sun, high temperatures, and adequate moisture, making it well suited to humid tropical and monsoon climates. It is an important food crop providing protein and vitamins for rural communities across Asia and is cultivated as a commercial vegetable in many tropical countries. The species is also grown in tropical America and Africa. Being a domesticated cultivar complex, its conservation status is not formally assessed in terms of wild populations, though the preservation of genetic diversity in cultivated landraces is an agricultural priority.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
