Fellow Mammalogists.

As many of you are aware, science is in a state of turmoil in the United States. Recent efforts to drastically reduce government workforces and research funding for science will lead to many adverse consequences for Earth’s remaining natural ecosystems.
How many mammal species are there now? Updates and trends in taxonomic, nomenclatural, and geographic knowledge.
