Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Ontogenetic Sequence of Differential Gene Expression in Predator‐Induced Daphnia pulex

Molecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT In response to predators, many Daphnia species develop inducible morphological defenses. These traits are phenotypically plastic, meaning their production is suppressed in the absence of the predator. While previous studies have identified several neurohumoral factors and candidate genes involved in the development of the defenses, the ...
