The interesting thing I'm seeing with keepers is everything is generally fine, but there's sometimes wild cold snaps that are hard to predict now. Still a ways from affecting crocodilians tho from what I understand
With 4 different Ice Ages on earth, and we are technically still at the tail end of the last Ice Age, how did these animals survive during those Ice Ages?
Many did not. The last ice age caused many extinctions. Just like through the current human caused mass extinction I think some things will survive, but many will (and have) go extinct
Crocodilians survived the Mesozoic, when land temperatures were much higher and ocean temperatures were much higher too. In essence, the spread of crocodiles in the oceans is limited by water temperatures, which are much lower than in the Mesozoic and early Cenozoic. Warming climate = greenhouse effect = more rain = more waterlogging. Sea levels will rise, but new swamps will also appear.
Right, it’s just a question of adapting fast enough to be able to keep up, with other human pressures already affecting populations and many species being critically endangered already. The many species that are already endangered would have a high probability of going extinct
Agree. But there are other factors, for example, climate warming has always led to increased speciation among reptiles in general. Some species are at risk of extinction due to hunting alone, but some good conservation efforts give hope that if this pressure is relieved, the population will recover to normal levels (although it will take a lot of time). Another factor is natural hybridization among crocodilians, which can also lead to the formation of new species. I have read that Cuban and American crocodiles can reproduce successfully, as well as Saltyes and Siamese crocs. Btw, if South American iguanas crossed the Pacific Ocean and reached Fiji, then with the ocean warming, nothing prevents American crocodiles from doing the same. I'm absolutely sure that parthenogenesis could be a big part of this process.
At your comment about repopulating the crocs using temperature to engineer more females, I began to wonder what else in the environment is purposely altered by man to encourage or discourage different species of plants and animals - but not for altruistic reasons. Hopefully there are enough genuinely caring people in the mix to provide checks and balances.
Another great video Chris. It’s so disheartening the way humans are destroying this beautiful planet and causing problems for the wildlife. Habitat destruction and human encroachment will eventually lead to the extinction of so many animals. When the apex predators disappear, everything else will begin to disappear as well. We’re all interconnected. Please hug Casper for me and tell him I apologize for the damage humans are causing him and his buddies. 😊 Love and respect from Tennessee.
Thinking “they” as in the order of crocodilians will be fine is like saying “we”, as in our order of primates, will be fine. It’s like thinking because marmosets survived that “we” survived even though humans went extinct. Many crocodilian species are currently critically endangered and will likely go extinct in the next hundred years given current trends.
During interglacial periods, Alligator/Crocodile ranges would wax. During glacial periods their ranges would wane. They've been doing okay since the ice age began two to three million years ago. The swings between glacial to interglacial can and have been fast and dramatic. Many interglacials have been much warmer than this current one we live in. Please refer to Randall Carlson for the problems of the temperature measurements and ipcc and cherry picking of data.
The highest diversity of coral is in the Coral Triangle. This area corresponds to the hottest ocean waters. Coral bleaching is due to stress from excess nutrient and pollution runoff the mainland.
Crocodilians survived the End Permian and the KT. Fossilised tracks were found recently that showed they were still around even in the direct aftermath of the worst of it. They'll be fine. Even if they end up basking on the shores of Ellesmere Island, as they once did.
The fact remains things are changing at a much faster rate (thanks to humans) than the normal background change the planet experiences, affecting animals that are already dealing with other human pressures like pollution and deforestation that are causing massive declines. Climate change is a massive stressor on an already very stressed system with many species already critically endangered. The many species that are already endangered, which includes many crocodilian species, have a high probability of going extinct, ending those lines that have existed hundreds of millions of years. Imagine the species that survived all the previous mass extinctions just to forever end the lineage because of humans. Also keep in mind crocodilians as an order survived previous changes, not all the species. Many species went extinct at each event. Thinking “they” will be fine is like saying “we”, as in our order of primates, will be fine. It’s like thinking because marmosets survived that “we” survived even though humans went extinct.
@@GatorChris_ Oh, couldn't agree more. My comment was more directed at the casual comment-skimmer. And yes, the species took a huge hit each time. I'll admit, l still don't know whether to be glad or upset that the Carolina Butcher isn't around anymore. 😄 But yes, what we're doing to the planet is appalling and we've already charted our course. Ocean acidification, stratification, anoxia.. it's all happening right now and getting worse by the day. The maddening thing is that the planet has run the same experiment we're running now plenty of times in the deep past and we know precisely what we can expect. It's just never been run this fast before. The silica-carbonate cycle is an angry beast, and we're poking it with sticks. The fact some folk refuse to accept climate as reality bothers me much less than the fact that most folk don't know that human civilisation flourished during one of the most stable climate windows of the last 65,000 years. The planet isn't "always like this" it's actually almost never like this. Thanks for the reply, keep up the good work, mate. We love our crocodilians down here, too! 🇰🇾🤙🏼
Do you want to do something about the planet, politics are a great blok because they are the ones that makes the law and have a say in it. I am not a big fan of the political way of thinking about saving the planet. Plus you can only fote left or right and nothing inbetween. Greetings from the Netherlands
Blessings to you Chris. Been loving all the posting lately. Looking forward to seeing your big alligator tanks progress.
Thanks 👍
the hot chicks and cool dudes analogy is hillarious. i think i have heard it before, probably from you😂
Always nice to see Casper! Oh, and you too Chris 😊
The science part of it, is better to talk about anyways. Lol another great video today Chris, always Killin it with the great content
Thanks!
Enjoying all of your videos Chris
Wow, I never knew you can influence the breeding like that. Fascinating animals!
Right?!
As a Florida native. I cant believe he has haters. The man is a genuine genius that studies the care of animals
✮✮✮ *Your channel is a great example of how hard work and dedication can pay off* ✮✮✮🤩✌🏼
Thank you so much!
@@GatorChris_ 🤩✌🏼
Saltwater crocodile apocalypse is a real curveball
Interesting Chris..👍🏼👍🏼👍🏼👍🏼
Thanks 👍
Awesome vid Chris!!! How do you feel about Forever Chemicals Pollution impacting Alligators?
I enjoyed today's conversation
Thanks!
Loving all the videos Chris ❤
Thanks!
💚
Let’s goo crhiss 🎉

Invasion has affected the gators & crocs between people & pythons way more than any type of weather pattern.
How long can gator survive without water? You mentioned food but I do not recall info about water need
alligators have a pretty wide range of prey. but when it comes to climate change, its incredibly unpredictable.

QUESTION ?? IN THE FUTURE WOULD YOU HAVE A TOUR LIKE CASPER IN YOUR NEW SANCTUARY ??
Very interesting, why is Casper’s tail so long?
He has a normal alligator tail

The vast majority of human interactions with the environment is to alter it for our benefit it’s their expense
Are you going to take Casper to your place when you have to work there full time :)
No he will be staying with the outpost

Very sad to see how humans have messed up ecosystems
Crocodilians have been around since the times when both temperatures and CO2 % in the atmo was much higher, so they'll do just fine I guess.
Thinking “they” as in the order of crocodilians will be fine is like saying “we”, as in our order of primates, will be fine. It’s like thinking because marmosets survived that “we” survived even though humans went extinct. Many crocodilian species are currently critically endangered and will likely go extinct in the next hundred years given current trends.
@@GatorChris_ things change.
I think it would be good to get gators to hunt Burmese pythons.
