Conservation Research: Chase Animal Rescue Sanctuary Contributes to Turtle and Tortoise Study Challenging Evolutionary Theories of Aging

Even though humans live longer lives compared to their historical counterparts, we cannot escape the inevitability of aging. However, testudines – the order to which tortoises and turtles belong – may buck this trend by following a different pattern of aging compared to humans and other species. 

In a new study published in the journal Science, researchers used data contributed by Chase Animal Rescue Sanctuary in collaboration with other zoos and aquariums to examine 52 species of turtles and tortoises. The data recorded by Chase Animal Rescue Sanctuary in the Species360 Zoological Information Management System (ZIMS) enabled researchers to discover that, unlike humans and other species, turtles and tortoises defy common evolutionary theories and may reduce the rate of aging in response to improvements in environmental conditions. 

Evolutionary theories of aging predict that all living organisms weaken and deteriorate with age (a process known as senescence) – and eventually die. Now, using data captured by Chase Animal Rescue Sanctuary and others, researchers from the Species360 Conservation Science Alliance and the University of Southern Denmark show that certain animal species, such as turtles and tortoises, may exhibit slower or even absent senescence when their living conditions improve. 

Out of 52 turtle and tortoise species, 75% show extremely slow senescence, while 80% have slower senescence than modern humans.

“We find that some of these species can reduce their rate of aging in response to the improved living conditions found in zoos and aquariums, compared to the wild,” said study co-author, Prof. Dalia Conde, Species360 Director of Science, Head of the Species360 Conservation Science Alliance. “In addition, modern zoological organizations play an important role in conservation, education and research, and this study shows the immense value of zoos and aquariums keeping records for the advancement of science.”  

As  a commitment to conservation and animal welfare, Chase Sanctuary and Wildlife conservancy records data on the animals in our collection to contribute to species population management and conservation. This also helps ensure that our animals are well cared for. We are proud that the data we have collected and curated on the turtles/tortoises in our collection has contributed to this study, and helped researchers better understand aging in these species.

Chase Animal Sanctuary and Wildlife Conservancy  is a member of Species360, a non-profit organization which maintains the Zoological Information Management Systems (ZIMS) – the largest database on wildlife in human care. As part of Chase’s  commitment to conservation and providing high standards of animal welfare, it uses ZIMS to keep detailed records of its animal collections. And as a holder of turtles and/or tortoises, Chase has actively collected and shared data in ZIMS on this species which has directly contributed to this study. 

Turtles keep growing after sexual maturity

Some evolutionary theories predict that senescence appears after sexual maturity as a trade-off between the energy an individual invests in repairing damages in its cells and tissues and the energy it invests in reproduction, so its genes are passed to the next generations. 

This trade-off implies, among other things, that, after reaching sexual maturity, individuals stop growing and start experiencing senescence, a gradual deterioration of bodily functions with age. 

Theories predict that such trade-offs are unavoidable, and thus senescence is inevitable. In fact, this prediction has been confirmed for several species, particularly mammals and birds. 

However, organisms that keep growing after sexual maturity, such as turtles and tortoises, are believed to have the potential to keep investing in repairing cellular damages and are thus thought to be ideal candidates for reducing and even avoiding the harmful effects of aging. 

“It is worth noting that the fact that some species of turtle and tortoise show negligible senescence does not mean they are immortal; it only means that their risk of death does not increase with age, but it is still larger than zero. In short, all of them will eventually die due to unavoidable causes of mortality such as illness,” said another of the researchers behind the study, Dr. Fernando Colchero, Principal Statistical Analyst, Species360 Conservation Science Alliance, and Associate Professor at the Department of Mathematics and Computer Science, University of Southern Denmark.

My friend & I, along with her adult son, did the Yoga with Lemurs. It was awesome! Then we were able to join on one of their tours to see all that the Sanctuary was. We enjoyed it immensely! A definite bucket list item for me! We intend on returning soon! Thank you to the hard & selfless work the volunteers do for those precious animals. I just wish I lived closer to be a dedicated volunteer myself!

We had an amazing time today at yoga. It was one of the most fun and relaxing experiences. The staff was incredibly nice. I loved that the animals weren’t forced to interact. Some of the lemurs wouldn’t come out so they let out a different type of monkey. Everything was voluntary on the animals part which made it that much more enjoyable. The deer and Patagonia Mara were also a pleasant addition. Looking forward to going back again.

We had an amazing time during lemur yoga! It was such a fun experience being able to interact with the animals and having them running around during yoga. We also liked how well cared for the animals are, it never felt like they were being exploited for our entertainment. This was such a wholesome and fantastic opportunity and we would definitely go back again!

My friend and I attended lemur yoga. It was such an interesting experience. I didn’t know what it would be like but we were completely surprised in a good way. The lemurs were friendly, gentle, didn’t smell funky (yay to that!) and were soft like a chinchilla. The other attendees were also nice people. There were extra animals out during yoga. All was wonderful. I suggest bringing a towel with you to clean your hands off after feeding bits of fruit during yoga.
