Dr. James Wetterer's PCB 2174 Honors Behavioral Ecology class took students on a field trip to learn about minature horses used as therapy horses. One of the students in the class, allowed us to visit her family home and stables.
Here are a few images. They also have many other horses, and a goat! I am determined to find a way to get a goat for the library as a therapy animal! Afterall, there is such a thing as library cats, so why not library goats!!
Here are a few more links to read up on the subject of mini therapy horses:

In attempts to fight the Asian tiger mosquito, an invasive species that spreads diseases like zika, the Environmental Protection Agency approved the use of Wolbachia pipientis, a bacterium that can infect and eliminate this species of mosquito. A biotech company [Mosquito Mate] will raise male mosquitoes, infected with the bacterium and release them in 20 states. The infected males will mate with the female Asian Tiger species. The females will lay eggs that will not hatch, eventually killing of the species.
“The EPA decision excludes much of the southeastern United States, which is home to dense populations of mosquitoes and a long mosquito season, because MosquitoMate did not conduct field trials there” [Waltz, 2017].
To read more about this experiment and trial release of mosquitoes, follow the links below.

I have included links to descriptions of the various viruses that are carried by the Asian tiger mosquito.

The recent Hurricanes [in Florida, Puerto Rico, Houston and other areas] brought many unseen hazards to people affected by flood waters. These waters mix with everything on and under the ground. Industrial solvents and chemicals, animal waste, sewage and pesticides get washed into the flood waters; not to mention sharp objects and unexpected wildlife [snakes, alligators, ants, and rats—to name a few](Brodin, E., 2017).
For those that must wade through and interact in these waters there is potential for spread of diseases and infection. Some of those can be very serious. A few of these potential hazards include leptospirosis, ecoli and vibrio.
Below is a short list of a few resources on the topic. Click on the links to learn more about the dangers lingering in flood waters around the world.

While on twitter, I ran across a video short on wolves in Yellowstone National Park. This lead to more research on the importance of large predators related to ecosystem health and balance.
I thought I would share some of those resources here.
Here is a brief summary on the topic [excerpted from one of the articles listed below].
The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the opportunity to examine the cascading effects of carnivore-herbivore interactions on woody browse species, as well as ecological responses involving riparian functions, beaver (Castor canadensis) populations, and general food webs. Our results indicate that predation risk may have profound effects on the structure of ecosystems and is an important constituent of native biodiversity [Ripple and Beschta, 2004, p.755].

Hippo deaths in Namibia
The Daily mail is reporting that 109 hippos have died in the Bwabwata National Park since Sunday last week. The cause of death is suspected to be a natural outbreak of anthrax. Outbreaks are not uncommon and can occur when rivers are running low. The hippo population before the outbreak was thought to be 1,300. Hippopotamus are listed as Vulnerable on the IUCN Red list. Veterinarians are still working to confirm the cause of death [anthrax].
To read the full report and read more about what Anthrax is, you can follow the Link to the full article on Daily Mail here
The Center for Disease Control also has a page explaining anthrax, which you can access here.
The CDC web page also had this graph of the Anthrax life cycle:
