Trade‐offs between surviving and thriving: A careful balance of physiological limitations and reproductive effort under thermal stress

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Balancing survival and reproduction presents a fundamental evolutionary challenge, especially in extreme and unpredictable environments. Thermoregulatory behaviour, in particular, imposes a costly trade‐off, as time spent maintaining optimal body temperature precludes ...
