To date, the knowledge of bee diversity in the Baja California Peninsula has primarily relied on large, sporadic expeditions from the first half of the 20th century. To address the knowledge gaps, we conducted extensive fieldwork from 2019 to 2023, visited entomological collections in Mexico and USA, and accessed digital databases and community science platforms to compile records. As a result of our field surveys, we identified 521 morphospecies, with 350 recognized as valid species, including 96 new records for the Baja California Peninsula and 68 new findings for Mexico, including the rediscovery of Megachile seducta Mitchell, 1934, ranked as possibly extinct.

Climate and landscape changes can significantly impact species distributions, driving some to extinction. The Forest Owlet is an endangered bird considered extinct but rediscovered after 113 years in 1997.

Twenty years of squandering an opportunity to save an iconic species from extinction are summarized. In 2005, an article that was featured on the cover of announced the rediscovery of the Ivory-billed Woodpecker () in Arkansas. Despite a subsequent report of sightings in Florida by another group of ornithologists, the persistence of this elusive species became controversial when nobody managed to obtain a clear photo.

Fundamental ecological knowledge is crucial for effective conservation management of these species, but it is particularly lacking for small, cryptic mammals. The Julia Creek dunnart (), a threatened, cryptic carnivorous marsupial that occurs in scattered populations in the central west of Queensland, Australia, was once so poorly studied that it was believed extinct.

Article Synopsis
- A database was created to track lost and rediscovered tetrapod species, revealing a faster loss rate than rediscovery, especially for amphibians, birds, and reptiles.
- The study highlights specific regions and species types that are at risk of being lost, which can help focus conservation efforts on finding these species.
- It identifies factors that affect rediscovery chances, indicating that some species may remain hidden due to their characteristics or habitats, while others are more likely extinct, guiding future conservation strategies.
