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. Population 1985 2015 Cheetah (Africa and Iran) ~21,000 <10,000 (CCF) Lion (African and Asia) 100,000 ~23,000 Africa; <400 Asia (IUCN) Tiger (6 subspecies) 5,000-7,000 <3,500 (Global Tiger Initiative) Leopard (9 subspecies) no reliable data 100,000 Africa; 8,000 India (Nat Geo) …

What New Legislature in the U.S. Means for the African elephant

January 15th, 2015tinalc0 Comments

From 2010-2012, the world lost more than 100,000 African elephants. At present, it is estimated that we lose 98 elephants a day. The biggest threat to both African and Asian elephants continue to be poaching to fill the demand of a thriving illegal ivory trade in China, the U.S., and Southeast Asia. In July 2013, President Obama revealed his Executive Order on combating wildlife trafficking, a proposed ban on all commercial trade in elephant ivory in the U.S. Working with preexisting legislature to close legal loopholes, the order will amend the Endangered Species Act of 1973 to include African elephants. …

Make 2015 the Year of Conservation Achievements

January 5th, 2015tinalc0 Comments

As 2014 came to a close, I felt inundated with reports of record numbers of animals killed to fuel the illegal wildlife trade. In 2014, almost 1,200 rhino were killed for their horns. Numbers of elephants slaughtered for ivory were in the tens of thousands. It appears that life in the sea is just as dangerous on land as over 100 million sharks were killed for their fins. Gorillas, tigers, okapis, hippos, lions, and cheetah are not only losing their lives, but also their homes. Sadly, they are not the only ones. This cannot continue. As we begin 2015, …

Lionfish: Invasive Predators of the Deep

December 17th, 2014tinalc0 Comments

Native to reefs in the Indo-Pacific region, the lionfish is a member of the scorpion fish family. Growing upwards of 45 cm in length and 1.3 kg in weight, it is an aggressive, territorial species with very few predators likely due to the fact that they are venomous. Large spins located within the dorsal, anal, and pectoral fins are capable of delivering a mix of the neurotransmitter acetylcholine and a neuromuscular toxin causing pain, swelling, respiratory distress, and, in some cases, paralysis. With a life span of 5-15 years, chemical arsenal, and a ferocious appetite, this is one species …

Conservation Achievements in the Pantanal

September 15th, 2013tinalc0 Comments

Listed as an UNESCO World Heritage Area and one of the world’s largest tropical wetlands, the Pantanal covers 188,000 ha in western central Brazil. Bordering Bolivia and Paraguay, this freshwater ecosystem, fed by the Cuiabá and Paraguay rivers, is home to a variety of species found nowhere else on Earth. Modern pressures and an ever-growing human population continue to pose challenges for wildlife conservation and habitat preservation. Research projects centered on such species as the lowland tapir, giant river otter, and jaguar work relentlessly to mitigate human-wildlife conflict and secure safe rangeland to ensure wildlife are protected and given the …

World Oceans Day: Why it Should Matter to All of Us

June 7th, 2013tinalc0 Comments

Did you know that 8 June is World Oceans Day? Like all days of designated observance, World Oceans Day was started to bring a yearly awareness, in this case to the state of our underwater world. Although water makes up ~70% of Earth’s surface, our seas remain one of the most unique, important, and yet unexplored parts of our world. As vast as our marine areas are, they are also extremely fragile, quickly being destroyed from an ever-increasing pressure by an ever-increasing human population. I suppose it is easy to dismiss what we do not see on a daily basis; …

The Internet Influence on Wildlife Conservation

April 22nd, 2013tinalc0 Comments

Dissemination of information has never been easier then at this very moment. The Internet, specifically social media sites, allows us to share concerns regarding wildlife and bring attention to important conservation issues instantly with people around the world. Case in point, you are reading this blog. Unfortunately, along with the potential good this kind of technology brings there is also the bad. With millions of daily tweets, Facebook status updates, Youtube videos, Instagram pictures, Flickr uploads, and blog posts one cannot help but ask if this actually helps or hinders wildlife conservation. There are not too many wildlife conservation …

Can CITES Regulations Help Protect Wildlife?

March 13th, 2013tinalc0 Comments

From 3-14 March, the Convention of International Trade in Endangered Species (CITES) is holding their Conference of Parties 16 (CoP16) in Bangkok, Thailand. While some species will get the protection they so desperately need to survive in the wild, others seem to fall by the wayside. What constitutes a species being placed on the coveted Appendix I list? Is a down listing to Appendix II or III, or a delisting a death sentence for species? Do CITES regulations really help protect endangered species or simply pay lip service to the angry mob? A great deal of confusion surrounds what CITES …

Love is in the Air . . . and Babies on the Way

February 11th, 2013tinalc0 Comments

In honor of Valentine’s Day, I thought it only fitting to take a closer look at baby making, and rearing, in the animal kingdom. Being a reproductive physiologist by training, I am always very fascinated by the ways wildlife have adapted to ensure species survival. How animals have evolved to overcome harsh environments, predators, and lack of resources, to name a few, to reproduce and raise young is incredible to say the very least. Thanks to the children’s animated feature, Happy Feet, most of us have at least a basic understanding of the yearly mating and egg laying drama of …
