The majority of species  around the world are declining from habitat loss. Biodiversity is valuable for human health and wildlife, but current conservation practices focus on individual species and not the ecosystem. Therefore, we should begin to aim conservation practices to protect the habitat; allowing for better corridors, and greater biodiversity.

EPISODE NOTES:

Pandas, Koalas, and Elephants. We know of these animals in part due to the incredible effort to conserve them. However, conserving a singular species in an ecosystem is not nearly as valuable as conserving the habitat itself. Join us on an adventure from your own couch, as we explore the benefits of protecting the entire ecosystem. From wildlife to humanity, we all benefit from nature. We hope that this episode also teaches you how to help nature, and promote large conservation efforts. Remember, this is Nature and Nature needs you.

Monarch butterflies are beautiful insects and have an interesting life cycle and migration pattern, but they are rapidly declining into possible extinction. Therefore, everyone should take steps to plant, protect and improve monarch breeding habitats across North America.

Human actions are leading rises in global temperatures and brachycephalic (smush-faced) dogs are increasing in popularity, but these dogs are at an increased risk of developing heat-related illnesses. Therefore, it is important to know the clinical signs associated with heat stroke to help best prevent this disease.

EPISODE NOTES:

Brachycephalic dogs, well-known as our “smush-faced” friends (think: English bulldogs, French bulldogs, pugs, Boston Terriers, etc) have been rising in popularity in both the US and UK in the last decade. As adorable as these dogs are, both in looks and in temperament, these breeds are predisposed to heat-related illnesses. Considering this, rising global temperatures due to climate change will only increase the risk for these dogs. Join us as we explore why brachycephalic dogs are so prone to heat stroke, the signs to look for in your pets, and what you can do to help against climate change.

Natural disasters are increasing in intensity and severity and companion animals are often adversely impacted however they have not been included in evacuation plans historically, so communities and rescue organizations need to work together to provide adequate resources for companion animal owners in preparation for disasters.

Episode Notes

In the most recent IPCC report, it was stated that extreme weather events are becoming more frequent and severe. Humans and animals alike will be negatively impacted by these natural disasters. In Hurricane Katrina, Snowball, a little dog that could not get on the evacuation bus with his child owner spurred the PETS act. This act states that FEMA will only provide funds to organizations that include plans for the rescue and essential needs of animals. This episode covers the progress that’s been made in disaster planning since the PETS act was implemented and how you can be prepared for a natural disaster before it hits your area.

Cyanobacteria is a deadly toxin and is found in fresh and brackish bodies of water worldwide but it is increasing in prevalence due to climate change and urbanization therefore we need to do more to increase awareness and prevent future blooms.

Episode Hosts: Angela Warner, Lauren Rush & Val Wright

Audio Engineer: Ethan Fagre

Special Guests: Dr. Claire Tucker & Dr. Daniel Gustafson

Episode Notes:

Blue/green algae (cyanobacteria) is found in fresh and brackish bodies of water and is DEADLY to animals and humans. Due to increased urbanization, water runoff and climate change these algal blooms are increasing worldwide. Join us to learn more about the biology of this toxin, what people may or may not already know about cyanobacteria, clinical signs and cases in dogs (the companion animal most likely to die from this toxin) and ways we can all help to prevent/lessen the incidence of these dangerous blooms.

Hiking with our dogs is a healthy activity and we want to protect our outdoor spaces, but dogs and their owners have a big impact on the environment. Therefore, it is important to educate ourselves on how to implement the best practices for hiking with our dogs. We interview Isabella Harris to learn more about the impacts of dogs on trails and what we can do to preserve them. Together, we can work to connect with nature and take care of the world around us.

Climate change is causing increased global temperatures, and this is expanding the range and season in which Heartworm is found. But not every client is diligent in administering heartworm preventatives, therefore veterinarians need to adapt their educational tactics to help minimize heartworm infections.

Episode Notes: With the climate continuing to change, the habitats of mosquitoes are expanding, and may be increasing the potential of your furry friend contracting heartworm disease. We talked to Dr. Marianne Krumdick to get the scoop on both treating heartworm as a veterinarian and juggling a heartworm positive pup at home.  Listen for more information about climate change, heartworm prevention and treatment, and more!

Ecotourism is a valuable tool to promote conservation and provide support to local communities, but it can also have negative impacts when practiced irresponsibly. Therefore, ecotourism should be practiced conscientiously so that the rewards outweigh the consequences.

Special Guest: Dr. Mike Cranfield

Episode Notes:

Ecotourism is meant to be a way to combine sustainability, travel, and natural experiences. Ideally, a successful ecotourism program supports and contributes to its surrounding local community. Often times, we think of ecotourism through experiences like Gorilla trekking, or safari, but it also includes guided trips through national parks, and other natural areas that might be in your own backyard. This podcast explores the highs and lows of ecotourism and provides tips to be a more responsible ecotourist in your backyard.

With rising temperatures and a changing climate, the range of disease vectors continues to expand into novel areas. This will expose people and animal populations to new diseases, but this issue is seldom discussed in public discourse. Therefore, we bring this issue to the forefront using bluetongue as a model for expanding vector-borne diseases, their impacts on livestock populations, and how we can best enact change in our communities and beyond.

Summary:

We spoke to Cam the Ram, Colorado State University’s beloved mascot, in order to get a better understanding of what’s been bugging him about climate change. One problem he kept ruminating on was the potential influence of climate change on vector-borne diseases. We began to investigate the issue of vector-borne diseases and discovered that they will increase in prevalence with rising temperatures. Warmer temperatures allow vectors to expand into novel ranges, increase their infective seasons, and change their transmission dynamics. We focused on bluetongue virus disease (BVD) to tell the story of vector-borne diseases of particular note to Cam. In order to do so, we called on the knowledge of Dr. Christie Mayo (DVM, PhD) from Colorado State University, an expert on BVD and virology to give us the inside scoop.

Episode details: 

On this episode of VetCAST, we discuss marine hybrids, ranging from teeny tiny living coral reefs to the largest animal to have ever lived, the blue whale. We interview Dr. Brendan Kelly to find out a little bit about how hybridization occurs, the ways climate change may be expediting this phenomenon, and what we can do to help.
