Lost and Found.

A recent study published in Global Change Biology has compiled the most comprehensive catalog of lost and rediscovered species to date. The catalog reveals that there are currently 856 missing species, with the number continuing to grow. While some lost species are likely extinct, others, particularly small reptiles, may still exist. The study also found that island-dwelling mammals are more likely to be extinct, and birds are typically rediscovered after an average of 66 years. The findings from this study are being used by conservationists to prioritize search efforts and protect rediscovered species. However, the publicity surrounding rediscoveries can also attract poachers and tourists, posing a threat to the species. Each extinct species represents both an ecological and cultural loss, highlighting the interconnectedness of all species on Earth. [Extracted from the article]
