Venus’s equator is likely to be hot despite everything our descendants do to shade the planet. It may be too hot for all but extremophile life forms. But that doesn’t mean they should not try to add life to Venus’s equatorial continents. However any life forms which are added will need to be preconditioned for heat by replacing some proteins, enzymes and other organic chemicals with equivalents which are more stable and better able to function in high temperatures on earth. This might mean taking the gene which expresses a particular protein from a heat tolerant algae, and moving it to a fig tree to perform the same function on Venus.
This is likely to be a complex process as many thousands of genes may need modifying before a plant, animal or fungus becomes ready for life in equatorial Venus.
However even with these modifications, other strategies to reduce heat exposure will be important; such as living underground. Fruit bats are likely to be the animals most at risk of overheating as they will be needed to fly over virgin lava and plant the seeds of figs and other trees in their droppings. Even if they are nocturnal, underground roosts will prevent them from being exposed to high daytime temperatures in tree roosts. They would also need guidance so that they could find their way into caves from bioluminescent bacteria growing on the cave walls.
This logic is less relevance to birds, which like most animals would seek the cooler temperatures of deep forests. If trees are able to grow taller and faster than in earth due to higher temperatures, plentiful water and nutrient supply and plenty of carbon dioxide; then the deep forests will indeed be protected from the intense heat.
