Expert warns of food consumption habits amid rising prices
A new survey by Dalhousie University's Agri-Food Analytics Lab asked Canadians about their food consumption habits amid rising prices.
A new study has identified more than 500 “lost” animal species not yet considered extinct but that have remained unseen by anyone for more than 50 years.
While animal extinctions are expected to increase in the coming years, extinction pronouncements remain uncommon due to difficulties in determining when the last individual of a species has died, the study’s authors suggest.
The study, published in the peer-reviewed journal Animal Conservation, offers a first-of-its-kind global evaluation of all terrestrial vertebrate species that are missing but not extinct, identifying a total of 562 lost species (137 amphibians, 257 reptiles, 38 birds and 130 mammals).
Data from the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species on 32,802 species was examined. Of the lost species identified in the study, 13 per cent (75 species) are listed as ”possibly extinct” by the IUCN.
Researchers note that the existence of such species may become increasingly problematic, as their presence may generate confusion in conservation priority efforts and our understanding of extinction rates.
"We hope this simple study will help make these lost species a focus in future searches,” said Gareth Bennett, an undergraduate student at Simon Fraser University who is credited with much of the data combing in the study.
The researchers suggest future survey efforts should focus on the identified “hotspots” in the study such as Indonesia, Mexico and Brazil, where the presence of many specific species is still in doubt.
