Decision making in wildlife management is always challenging; some may bias towards wildlife and others towards human needs. This conflict can be resolved only by making decisions based on facts or scientific data, which constitute a form of “evidence.” Thus, evidence-based decision making is considered the best approach to managing wildlife and habitats around the world. The opposite of this is management based on emotion, political agendas, or even expert opinion (which can often be wrong). Continue reading
Some colleagues at the Denver Museum of Nature & Science have started a series featuring conversations by female scientists called Skirts in Science. The goal is to make women in science more visible to students, especially young women and girls.
I had a lot of fun in this chat with Sarah Benson-Amram, now faculty at the University of Wyoming. Here is a brief window into our work:
Many thanks to Paula Cushing, Kimberly Evans, and Marta Lindsay for inviting us to be part of this great series. Check out their channel here.
Part 2 will have a discussion of how we came to do what we do. Stay tuned!
We are pleased to release EARS (Elephant Attribute Recording System), designed by intern Ilja Van Braeckel. EARS is an MS Access database that permits quick searching of elephant ID photos. Users enter new ID features using a simple Excel worksheet which can be copied directly into Access. They can then query the database with a set of check-boxes for prominent natural features of individuals, which returns matching IDs and photos. This should narrow the search substantially and cut down search time. We recommend that a separate set of high-resolution ID photo files are maintained in parallel at another location and that once the search is narrowed final identifications are confirmed using these external files. The idea is for the database to aid, not replace, more detailed photos and human memory.
We share this tool freely hoping it will help others conduct individual-based studies of Asian elephants, and modifications may be made as required. Variations of it may also be useful for other species and contexts.
The database, excel sheet and a user manual can be found at:
