The Perspectives Series is a student-created, student-managed publication whose mission is to communicate conservation research being conducted by undergraduates, graduate students, and faculty in the field of applied biodiversity to a broader audience of academics, practitioners, and the public.
The collection of articles in this year's Perspectives Series shares with you the insights and experiences of graduate students and faculty focused on conservation and biodiversity issues in Africa.
Applied biodiversity brings multiple perspectives together—from ecology and psychology, to genetics and anthropology—to address the global challenge of reducing the loss of biodiversity and its impacts on human livelihoods.

The innovative part of this analysis was the addition of a comparison to other species who are recognized to have subspecies and show similar Sub-Saharan population distribution. The study identified 46 animals that show a distinction between West/Central African and East/Southern Africa populations. While some animals are recognized as being more than one species – known as a complex – such as Baboon (5), Rock hyrax (5) and Oryx (3), others are species separated into subspecies, such as Giraffe (9; below), Black (4) and White (2) Rhino, and Caracal (8). Only 13 of the 46 animals aren’t separated between West/Central and East/Southern, including the lion, according to CITES.
The ESA classification is a little closer to demonstrating the Sub-Saharan distribution taxonomically by clumping the West/Central population with the Asiatic population. However, based on these results, lions may be able to be classified even more specifically. Hopefully my research will be able to shed a little more light on this. The help Laura is giving me to continue this investigation is immeasurable.

Your support is much appreciated! THANKS!!!
This month’s College of Veterinary Medicine Graduate Student Association Meeting had a very interesting guest speaker. Dr. Henry Musoma of the Mays Business School spoke to us about the Journey from Pathetic to Prophetic and, basically, how to be a good person, particularly in academic research. His speech took up almost the entire meeting time and was incredibly entertaining and meaningful.
Without rehashing his entire speech, he made some good points that I wanted to share:
He ended his speech by saying, “Don’t be impressed by me, be inspired by me.” I think the humility in this statement speaks wonders.
The manuscript I have been working so hard on for most of the year has finally been published!
My first publication, Mitochondrial Haplotype Diversity in Zambian Lions: Bridging a Gap in the Biogeography of an Iconic Species, was made live today, December 16th, 2015! I am now officially a published author!
The paper is about matrelineal gene flow and genetic diversity of lions in Zambia. We found that lions in Zambia have a high level of diversity but can be separated into two sub-populations with little to no matrelineal gene flow between the two. The separation could be historical but it more likely due to an expanse of cities and roads that inhibit modern day dispersal because, when put in context with the entire range of the African lion, Zambia acts as a bridge connecting Southern and Eastern lion populations. This is all based on analysis of mitochondrial genes and the discovery of 5 sets of DNA variations (haplotypes) thus far not seen anywhere else in Africa.
Here's my official citation:

I am currently working on a press release for this paper and I have already started writing my next publication, hopefully with two others soon to follow after that. My goal is that by the time I finish my PhD I will have at least 5 publications. Let the fun begin!
It was too cloudy in College Station to see the eclipse. It's nice that someone was able to capture a magical moment!
The lions have been almost fully "reintroduced". They have been awakened in Rwanda and initial introductions have been made in the form of quarantine bomas. They will spend 14 days in these bomas acclimating to their new Rwandan home and getting used to the sites, sounds and smells of their new home. Apparently, the local baboon troupe isn't too happy about it.
The non-profit African Parks, an organization charged on taking total responsibility for the rehabilitation and long-term management of national parks in partnership with governments, wildlife organizations and local communities, was responsible for the management of the translocation efforts. They are a management organization with a focus on the generation of sustainable income streams to pay for running costs and capital replacements. Although they seem to have an economic focus, they do have a conservation approach and mention long-term biodiversity restoration in their model. This seems like a great organization, taking on the financial burdens that often plight national parks, my only concern is that with this move of South African lions into Rwanda rather than eastern African lions into Rwanda is that the individuals making the decisions regarding long-term biodiversity restoration may not fully understand what biodiversity and biodiversity restoration means.
Lions went extinct in Rwanda 15 years ago after the 1994 genocide when the Akagera National Park went unmanaged and cattle herders poisoned many of the animal species. And this week, in a big conservation effort, seven lions, 5 females and 2 males, are being relocated from the South African province of KwaZulu Natal to repopulate Rwanda with lions. They are starting their journey from OR Tambo International Airport in Johannesburg to Rwanda today!
7/1/2015 - While doing a bit more research combing through article after article reading the same shpeal over and over I finally found something that somewhat confirmed my suspicion but with no real concrete evidence... there is political mumbo jumbo afoot....
The Christian Science Monitor (um, the what?) says that Kenya offered to donate eight lions to Rwanda last year but Kenya's wildlife conservation groups fiercely opposed the plan saying "Rwanda had not sufficiently addressed issues that resulted to the loss of its own lion population."
A ban on the hunting of big cats in Zambia, which has been in effect since January 2013, was officially lifted a few days ago. Hunting of leopards will resume at the end of this year/beginning of next and hunting of lions will return about a year after that.
Zambia, however, is one of 5 countries to have lion populations 1000+ individuals strong and, in areas with thriving lion populations, a hunting ban could actually have potentially deleterious effects (and not just on eco-tourism). Studies have shown that the presence of hunters deters poachers, providing protection for the habitat and other animals. Revenue brought in by hunters also contributes to anti-poaching efforts as well as community assistance by providing jobs and other resources.
So, after the realization that a continued full ban in Zambia on hunting for big cats could be damaging for the population (and economy), the government decided to reinstate hunting under the pretense there will be “cautionary quotas.” Tourism and Arts Minister, Jean Kapata, said "safari hunting was profitable and good for off-take of wildlife and could benefit the whole country if well nurtured." The study I just submitted for publication will (hopefully) be used to help with decisions for setting quotas and implementing management to prevent loss of diversity while big cat hunting is permitted.
I just wanted to share this nifty little pictorial example I found of trophic levels (aka what Mufasa talks to Simba about in the Lion King fondly referred to as "The Circle of Life"). Nants ingonyama bagithi Baba!
A white lion cub, a very rare color morph, has been causing quite a stir amongst visitors a Kruger National Park in the Republic of South Africa (mostly because he's so darn cute). This little rarity is a member of the Satara Pride and is one of only 13 wild white lions. White lions are so rare that none were seen in the wild from the early 1990's until 2006. And since 2006, only 16 white lions have been born and in only 5 lion prides, all in the Kruger/Timbavati region.
Why are they so rare?
White lions are a result of leucism, or lack of pigment which results in light coat and eyes. In lions, leucism is caused by getting a copy of a gene which has a recessive mutation from both mom and dad. For two tawny lions (the typical brown/tan color) to have a white lion cub, both lions would have to be carriers of the recessive allele, meaning they have the recessive copy but they display the dominant one.
It is quite possible that the statistics are way more complicated and that there may even be more than one way to be 'white.' It has been speculated that light coat in white lions with yellow eyes may we caused by a different gene than in white lions with blue eyes (the TYR gene versus a gene similar to what creates white cats and white tigers). Genomic analysis of big cats is just beginning but don't you worry, we're getting to the bottom of it!
Just some elephant play time from August 2005... ENJOY!
Rest in peace my dear girl!
I am a biologist and my life is crap!
