Do Mountain Lions Target Bulls and Bucks?

I’m often told that mountain lions target adult male deer and elk, called bucks and bulls by many people. Its become a point of contention among deer and elk hunters, and has fueled persecution of mountain lions. We just published a paper in which we tested this assumption in two areas of the Rocky Mountains.

I share a longer blog about our results on National Geographic’s CatWatch. But in short, we found that mountain lions went out of their way to target the youngest age classes of deer and elk, not the adult males.

The full article published in Wildlife Research can be found here. If you’d like a copy, please send a message through our project Facebook page.  Thank you for your interest.

Scientists Warning to Humanity

In 1992, the Union of Concerned Scientists and >1700 scientists wrote the “World Scientists’ Warning to Humanity”. They warned of environmental destruction and warned, “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.”

Twenty five years later, scientists make the same plea. I signed the #ScientistsWarningtoHumanity.

Read the paper published in BioScience, spread the news.

Caption for the image adapted and shortened from that published in the paper by Ripple et al. (2017.) in BioScience:

Panel (a) shows emissions of halogen source gases, which deplete stratospheric ozone, assuming a constant natural emission rate of 0.11 Mt CFC-11-equivalent per year. In panel (c), marine catch has been going down since the mid-1990s, but at the same time, fishing effort has been going up. Panel (f) illustrates vertebrate animal abundance between 1970 and 2012– vertebrates declined by 58 percent. Five-year means are shown in panel (h). In panel (i), are increasing abundance of humans and ruminant livestock (domestic cattle, sheep, goats, and buffaloes).

 

Welcome, a Fresh Start

Well, it is exciting to finally have a website again. Its been more than 2 years since I gave up wildlifetrackers dot com, which was promptly hacked and still displays my name while now selling outdoor products. Please do not support the site. Have a look around and please let me know your feedback. Thanks.

There’s a lot happening in the mountain lion world right now, and I hope to write a few blogs about current issues. Stay tuned. Much more to come.
