Invasive and Unwanted, Iguana Euthanasia


This semester I am taking a Vertebrate Zoology class and the professor introduced us to a Facebook page, "Wildlife Issues" that has been a useful resource for keeping up with current events in conservation. For this week's blog post I was browsing the page and was surprised by a header on the timeline: "Florida's Solution to its Invasive Iguana Problem: Smash their Skulls in". Despite it's gory implications, the disposal of these iguanas is definitely a necessity, as explained in the article by the Washington Post. The Iguanas were originally native to a broad area ranging from Mexico to South America to the Caribbean and were brought to Florida as pets around 1966. Since then they have spread from Miami to the Keys and as far as Palm Beach.
To address the “smash their skulls in” portion, many biologists are going out with bolt guns to kill the iguanas, while the in-the-head portion is to reduce the suffering of the animals. The reason there is funding for the iguanas to be killed is that they are causing significant damage to waterways and are reducing the fruit and vegetation to levels where soil erosion is becoming an issue. Additionally, the iguanas have been known to carry salmonella and pose a significant health risk if their feces get into drinking waters or pools.
Despite the incentive to get rid of the creatures, laws preventing animal cruelty pose a risk, if you only injure the creatures you can receive up to $5000 fines. Furthermore residents are taking it upon themselves to get rid of the iguanas with pellet guns, as local legislature allows. Last thing of note is that, when possible, the scientists will capture the iguanas and euthanize them. All of the Iguanas are then studied and disposed of in a landfill. I swear I set out to write this in a positive light but it still sounds bad, invasive species are also bad, shrug.

SpaceX Paves the Next Wave of Space Explorations +bonus

SpaceX Falcon Heavy launching with 4 MerlinD1 Boosters For our final assignment in this Science writing class we have to write a feature story with a human element to draw readers in, I chose Elon Musk’s success in the privatization of space craft development and launch. Unfortunately this week I won’t be talking about that, apologies. I want to take a break from writing about current assignments because I am already tired of it and instead talk about what I wrote as a comment in another classmate’s blog. Book review round two, that’s right reader, today I will be talking about my favorite science fiction series, Ender’s game, and the trilogy that follows. For those that haven’t heard, the 2013 movie was actually adapted from a book of the same name from 1985, WOW. That book, written by Orson Scott Card, had genius boy Andrew Ender Wiggins thrust into a space militant training facility to develop the best minds into tactical war geniuses for the eventual return of the formics,...

Large Population of Adélie Penguins Discovered

A recent article highlighted in Nature Journey documents a new find in the Antarctic, a huge population of Ad é lie penguins on the Danger Islands . This population numbers in around 1.5 million individuals, that were previously not known to researchers. This hotspot for penguins was found with the assistance of aerial drones to access parts of the Antarctic Peninsula that were previously inaccessible by boat. This finding gives proof of concept to this method of data acquisition, and leads researchers to look in more remote places for tracking species more closely. Contrary to the general trend associated with climate change reducing Antarctic ice mass, this population of penguins has been largely unaffected; they will however, be considered in ongoing efforts of conservation due to their large significance in the region. Throughout the continent, Ad é lie penguin populations have decreased as much as 70 due to rising air temp and decreased ice packing’s effect on prey availabi...

Using Snow Coat as an Example of Climate Change and Adaptive Traits

Least Weasels as drawn by skilled illustrator In a recent study in Science Journal, climate researchers L. Scott Mills, et al, are using seasonal coat changes as an example to demonstrate the need for adaptive rescue strategies for saving species from human initiated climate change. Many species in snow covered areas have adapted to seasonal snow by possessing white coats in the winter and then shedding them for brown coats when snow is less prevalent, this trait is known as winter coat polymorphism. The study tracked the coloration of four species of hares, three weasles, and arctic wolves in relation to their geographical location and annual snow cover. Using over 2500 samples from over 60 countries the researchers determined ranges for the species sampled where there are white only, brown only, and both white and brown. This research is important for conservationists to recognize the effect adaption has on fitness in changing climates. It recognizes in discreet ways how ...
