January 21st, 2015tinalc0 Comments

Despite staunch conservation efforts, global big cat populations continue to decline. In just the last 30 years, data collected by conservation groups in Africa show that some big cat populations fell by at least 50% (table 1). Loss of habitat, human-wildlife conflicts, hunting, and poaching continue to threaten the long –term survival of these iconic creatures.

Wildlife Management: To Cull or Not to Cull?

February 26th, 2012tinalc0 Comments

I have always thought that “Wildlife Management” was a loose term. Regardless of geographical location, wildlife lives in fragmented habitats, held inside imaginary borders meant to protect and conserve. It is a daily struggle for humans and wild animals to co-exist. As the human population continues to increase, wildlife is pushed to the edge of extinction. Animals are culled to keep numbers in check according to management plans, as well as illegally poached for their parts or killed out of ignorance and fear. So what does it mean to manage wildlife? In the early 1900s, the United States government initiated …

The Year of the Dragon

February 20th, 2012tinalc0 Comments

The dragon is both revered and feared in many cultures around the world. This year the Chinese will celebrate the upcoming new year as the Year of the Dragon. A symbol of strength and royalty, you can find interpretations of these mythical beasts adorning clothing, wall tapestries, statues, and even etched into flesh. But what do we know about our last remaining dragon, the Komodo dragon, which still walks the earth? What is being done to conserve this magnificent creature and its habitat to ensure that it too remains immortalized? Weighing in at up to 100 kg (220 lbs) and …

Sharing Space With Wildlife

January 13th, 2012tinalc0 Comments

One of the first things we are taught as children is to be mindful of traffic. We know all too well the consequences of running across a busy street; doing so with blatant disregard would be considered suicide. Therefore, it is well established that roadways are the automobiles area, and we respect that. So why don’t we give the same caution in regards to wildlife? Why would we dare swim in crocodile territory in North Queensland, Australia? Why would we hike through Grizzly bear habitat without taking extreme precaution? Or why would we walk within meters of a wild elephant …

Extinction: The Final Countdown

December 7th, 2011tinalc0 Comments

The word extinction has shown up several times in the news lately regarding the population status of some wildlife species. All too often we can identify species that have been deemed extinct, but we are not given an explanation of how this came to be. Historically, or I should say prehistorically, we know that a meteor striking the earth and an ice age contributed to the extinction of thousands of species. Note that these catastrophic events were natural disasters. However, what about the extinctions as of late? Internationally, we still experience natural disasters all the time, but what is their …

7 Billion and Counting

November 5th, 2011tinalc0 Comments

Last month the world population reached 7 billion. In only 12 short years, since ~October 1999, the human population has increased by 1 billion. Let us take a few moments to think about the fact that we now share this planet with 6,999,999,999 other people… and counting. If our global growth rate continues, it is anticipated that by 2050, you could be one of 10 billion! So what exactly does this increase mean for the other species that share our space? Furthermore, what do 7 billion humans mean for the environment? Regardless, if we live in a developing or industrialized …
