Secret Weapons: Defenses of Insects, Spiders, Scorpions, and Other Many-Legged Creatures

  title={Secret Weapons: Defenses of Insects, Spiders, Scorpions, and Other Many-Legged Creatures},
  author={T. Eisner and M. Eisner and M. Siegler},
This book is dominantly about chemical defences of terrestrial arthropods, though other types of defences (camouflage, catapulting, sticky traps) are also mentioned. Chapters are short, and typically feature the defences of one organism, or at most a small group of related organisms. One or more colour photos, in themselves almost worth the cost of the book, enhance both the aesthetics of the book and the ability to drive home each chapter’s message. Chemical formulae are illustrated in those… Expand
The chemical defenses of millipedes (diplopoda): Biochemistry, physiology and ecology
Evidence suggests that the defensive glands of Glomerida arose independently of those of the Helminthomorpha, suggesting that chemical defense has been of significance in helminthomorph millipedes at least since the Lower Carboniferous. Expand
Invertebrate and avian predators as drivers of chemical defensive strategies in tenthredinid sawflies
It is concluded that the evolution of chemically-based defenses in tenthredinids may have been driven by invertebrate as much as by avian predation, and further studies on (prey) insect groups should include visual signals and other traits, to better interpret their relative significance and to refine the understanding of insect chemical defenses.

Chemical Defenses of Insects: A Rich Resource for Chemical Biology in the Tropics
This chapter is an introduction to the topic of arthropod chemical biodiversity and chemical defense, and an overview of insect venoms and other chemical defense studies, with a brief description of the importance of studying biosynthetic pathways in insects and other organisms. Expand
Predators as drivers of insect defenses
This study investigated which predator types evoke these types of defenses, through a review of the effectiveness of antipredator defenses in insects against carnivorous animals that are commonly used as model predators in studies. Expand
A novel property of spider silk: chemical defence against ants
A novel property of the silk produced by the orb-web spider Nephila antipodiana (Walckenaer) is reported, which suggests that this compound represents an adaptive response to the threat of natural enemies, rather than a simple by-product of silk synthesis. Expand
Ecological factors influencing the evolution of insects' chemical defenses
The evolution of antipredatory defenses will be relatively insensitive to the severity of any mechanism, whereby prey pay a cost every time they use their defense against an attacking predator even if they survive the attack, but sensitive to the form of the relationship between initial investment in constituting the defense and survival benefit. Expand
Behavior and body size modulate the defense of toxin-containing sawfly larvae against ants
The overall results suggest that the ability of Arge and Pergidae larvae to defend against ants is influenced by the body size and behavior of the larvae, as well as by chemicals. Expand
Investment in multiple defences protects a nematode-bacterium symbiosis from predation
Analysis of feeding trials of nematode-infected waxworms with wild-caught great tits found no overall benefit in terms of initial attack on the first prey item, although this does not rule out the possibility of multimodality within this system. Expand
Anti-predator defences of a bombardier beetle: is bombing essential for successful escape from frogs?
The results suggest that the frogs tended to stop their predatory attack before receiving a bombing response from the beetles, therefore, bombing was not essential for the beetles to successfully defend against the frogs. Expand
Behavioural defences of anurans: an overview
The role of predators in the evolution of defensive behaviours is still scarcely touched upon and this overview adds data to explore this and other evolutionary unsolved questions. Expand
