Carnivores are fascinating creatures that bring balance to ecosystems worldwide. From majestic wolves to agile cheetahs, these meat-eating mammals play a crucial role in maintaining the health of our planet. However, due to various threats such as habitat loss, hunting, and climate change, 25 percent of carnivores are now in danger of extinction.
Protecting Apex Predators for a Thriving Ecosystem
Large carnivores like wolves, wild dogs, and cheetahs are at the top of the food chain and require vast home ranges to support their populations. The preservation of these species not only safeguards their existence but also creates a positive ripple effect that ensures the survival of entire ecosystems.
At the Smithsonian Conservation Biology Institute’s Center for Species Survival, scientists are collaborating with partners in the United States and overseas. Together, they are spearheading multidisciplinary science-based conservation projects to protect and preserve wild carnivore populations in breeding centers and their natural habitats.
Cheetah Sustainability: A Triumph in Conservation
The Smithsonian Conservation Biology Institute (SCBI) plays a vital role in managing the North American cheetah population. Through the governance of the Breeding Centers Coalition, a group of nine facilities dedicated to generating self-sustaining populations, SCBI leads the way in cheetah conservation efforts.
SCBI hosts the cheetah Species Survival Program (SSP) leader, who acts as a bridge between in situ and ex situ research and education programs. Additionally, they work closely with genetic advisors and managers to oversee population breeding and transfer plans. Since 2010, SCBI has celebrated the birth of 60 cheetah cubs across 14 litters at their facility in Front Royal, Virginia.
Groundbreaking studies conducted by SCBI researchers have unveiled the benefits of maintaining breeding males in group coalitions, simulating their natural environment in Africa. This approach not only enhances reproductive performance but also improves sperm quality. Other significant research focuses on gamete biology, reproductive health, age-related effects on reproduction, and the intricate hormonal complexities of cheetahs.
Such scientific knowledge assists conservationists in modifying reproductive strategies for these endangered felids. One example is ensuring that prime breeding age cheetahs are maintained in groups within spacious breeding centers, like those at SCBI, to maximize their chances of successful reproduction and cub production.
Current Projects at SCBI
- Investigating AA amyloidosis prevalence in cheetahs and its implications for captive population management.
- Studying the impact of group management on male cheetahs and its influence on reproductive fitness.
- Understanding the physiological onset of puberty in cheetahs.
- Developing a pregnancy detection assay for endangered felids.
- Investigating cheetah sperm metabolic function.
- Extending the fertility of aging female cheetahs to improve population genetic health.
Global Canid Conservation: A Battle to Preserve Canid Species
Canids, the dog-like mammals ranging from the tiny 2-pound fennec fox to the mighty 175-pound gray wolf, are rapidly disappearing from our planet. Habitat loss, hunting, and disease have pushed five of the 35 living canid species to the brink of extinction. Among them are the dhole, African painted dog, red wolf, Ethiopian wolf, and Darwin’s fox. Several others, including the maned wolf and bush dog, are also facing imminent threats.
The Global Canid Conservation Program takes a scientific approach that incorporates reproductive biology, genetics, animal behavior, ecology, veterinary medicine, and education. This initiative aims to promote canid conservation on a global scale through three major elements.
The first element focuses on establishing innovative reproductive technologies to help sustain genetic diversity in wild canid populations. By implementing these technologies, scientists can play a crucial role in ensuring the survival of these endangered species.
The second element involves ex situ conservation efforts, aiming to address challenges faced by wild canids in zoos, such as poor reproduction and suboptimal health. This approach ensures that canids are well cared for and protected even outside their natural habitats.
Lastly, the program emphasizes field conservation research that actively engages local communities. By involving communities, the Global Canid Conservation Program encourages individuals to take part in protecting canids and their habitats, fostering a sense of responsibility for the well-being of these charismatic animals.
