Allometry of Defense: Predator Shift Alters Ontogenetic Growth Patterns in an Antipredator Trait

Bin Jiang,
Yu Yao,
Rüdiger Mauersberger
et al.

Abstract: Predation is a major factor driving prey trait diversification and promoting ecological speciation. Consequently, antipredator traits are widely studied among prey species. However, comparative studies that examine how different predators shape the ontogenetic growth of antipredator traits are scarce. In larval dragonflies, abdominal spines are effective traits against predatory fish in fish lakes, which prefer larger prey. However, defensive spines increase mortality in habitats dominated by invertebrate pred… Show more

“…Many insects have nonoverlapping generations, shaping discrete dynamics [ 3 , 4 ]. The dynamics of insect populations are not only influenced by various abiotic factors, such as temperature [ 5 , 6 ], altitude [ 7 ], and humidity [ 8 ], but also largely mediated by predator–prey interactions [ 9 , 10 ]. Refuge effects, a vital influence factor in the insect predator–prey systems [ 11 , 12 , 13 ], provides a degree of protection for insect populations from predation [ 11 , 14 , 15 ].…”
