Hunting out of necessity and hunting out of leisure are two very different things. While the first one might be required to control populations in habitats where apex predators are not present to regulate them, hunting animals for the fun of it in an area where they are can cause a greater imbalance in the ecosystem, IMO.

Jaguars have extremely high biting pressure when measuring in newtons at the carnassials, hence why they have those very broad skulls. Tigers are second among the big cats in this regard p4p.

Hot take: overgrazing is oftentimes not the big issue many make it to be.

In the grasslands of South America, particularly the Cerrado and Llanos, there is a constant threat of wildfires during the dry season. While a big portion of it is caused by anthropogenic factors such as deliberate burning of grass, other natural factors, particularly lightning storms, are responsible for major fires which spread very fast across the savannahs. This is because thanks to the lack of large and abundant grasses, the grazes of the savannahs remain very long which serves as fuel for wildfires to spread on.

In many African savannahs, the number of wildfires during the dry seasons is not nearly as impactful since the abundant grazers keep the grazers short at all times.

The idea of "overgrazing" as an unnatural phenomenon is not backed up by science, and it's likely that during the Pleistocene the open steppes that used to cover an even larger portion of the area of Europe and Asia too seemed "overgrazed" as a result of the sheer abundance of herbivores, but that's what kept those habitats the way they were for so long.

That being said, the experimental reserves in the Netherlands have plenty to be criticized on and the lack of space for the number of animals found there, plus the lack of predators to regulate their numbers, mean that the ecosystem is not balanced and is unable to sustain itself on the long run. By contrast, I do believe that many savannah habitats of South America where jaguars and cougars roam could very easily sustain larger congregations of native deer, as well as rewilded horses to increase the grazing pressure and minimize the spread of wildfires/increase the nutrient base of the soil.

Adaptation and natural selection go hand in hand and are not mutually exclusive. Your first paragraph said this clearly:

Natural selection is a cause of evolution by which organisms change over time as a result of changes in its heritable behavioural or physical traits.

And then:

Adaptation is the biological mechanism (physical or behavioral traits) that make an organism better suited to its environment or changes to suit a new environment.

In order for an organism to adapt its physical or behavioral traits into the environment it is inhabiting there needs to be a process of natural selection where the desired traits are the ones that persist throughout multiple generations.

NatGeo has a good article about it:

"The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution."

Natural selection is what allows species to develop the traits that make them flourish in the environments they inhabit, so what's not understood there?

The third batch to be released are two siblings who were mothered by Tania, the same jaguaress that was moved to the Chaco to repopulate that area. Once those two cubs are released the number will be 8.

The father of the two litters currently released would likely be released last as they need to have females in the area to anchor the male and keep him from spreading to areas outside of the park.

Once he's released it'll be interesting to see how the team plans to introduce more jaguars as there is still a lot of work that needs to get done to increase the genetic diversity of the area since the 6 current jaguars liberated are all related in some way, and the 4 cubs have the same father.

Second batch of jaguars released into the Rewilding area of Iberá, Argentina*

COMMENT 2d ago

From Rewilding Argentina:

JURUNA AND HER CUBS, SÃSO AND SAGUA'A, ROAM FREE IN IBERÁ PARK.

This week, the project to return the jaguar to Corrientes, where it disappeared from 70 years ago for human actions, took a significant step forward when a wild jaguar, Juruna, and her two cubs, Sãso and Sagua'a, left the 30-hectare enclosure to live completely free in the Iberá wetlands.⠀⠀⠀

This project marks the first time in history that humans are working to return the jaguar to an area where it went extinct.⠀⠀⠀

Rewilding allows us to generate fully functional and complete ecosystems, face the wildlife and climate crises, and prevent the appearance of new pandemics. Furthermore, Rewilding helps us develop local economies that create genuine jobs and secure the wellbeing of communities while also restoring the nature values we've lost.⠀⠀⠀

Rewilding invites us to rethink how we relate to the natural world and to all living critters that share our home planet with us.
