Chemical defences in embryos and juveniles of two common Antarctic sea stars and an isopod
The brooded embryos and/or juveniles of the sea stars Neosmilaster georgianus (Studer, 1885) and Lysasterias perrieri (Studer, 1885) and the isopod Glyptonotus antarcticus (Eights, 1853) were examined for their acceptability using the sympatric sea star Odontaster validus (Koehler, 1906) as a predator. Organic extracts were prepared from embryos of both sea stars and juveniles of Lyasterias per...
متن کاملPriming of indirect defences.
Leaf damage induces in many plant species the secretion of extrafloral nectar (EFN) and/or the release of specific odours (volatile organic compounds, VOCs). Both traits attract carnivorous arthropods and function as indirect plant defences by increasing the predation pressure on attacking herbivores. We have conducted field experiments in Mexico and found that plants that had been exposed to V...
متن کاملLung defences: an overview
Lung defences are dependant on a complex array of mechanisms in the upper airways, which must to be differentiated from those of the distal airways. However, the first lines of defence in the proximal and distal airways are predominantly based on mechanical barriers and several mechanisms related to innate immunity. If pathogens or antigens reach the interstitium, dendritic cells will take up t...
متن کاملBiometric attack vectors and defences
Much has been reported on attempts to fool biometric sensors with false fingerprints, facial overlays and a myriad of other spoofing approaches. Other attack vectors on biometric systems have, however, had less prominence. This paper seeks to present a broader and more practical view of biometric system attack vectors, placing them in the context of a risk-based systems approach to security and...
متن کاملHerbivore-induced, indirect plant defences.
Indirect responses are defensive strategies by which plants attract natural enemies of their herbivores that act as plant defending agents. Such defences can be either constitutively expressed or induced by the combined action of mechanical damage and low- or high-molecular-weight elicitors from the attacking herbivore. Here, we focus on two induced indirect defences, namely the de novo product...
