Parasites defy biodiversity rules, thriving far from the equator

Parasite infections in [tropical regions] often lead to higher mortality, which makes it harder for parasites to persist. In cooler temperate waters, hosts can tolerate infections better, giving parasites a chance to survive, reproduce and complete their complex lifecycles.

Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen

[The study] found that the space occupied by tracheoles in the flight muscle is typically only 1% or less in most species[.] This suggests that the flight muscles of insects are not constrained by atmospheric oxygen levels as they could easily add tracheoles in the muscle, since they take up so little space.
