Chemical Defence Strategies of Higher Fungi
Chemistry – A European Journal, 2008AbstractLike plants, fungi have evolved a variety of defence strategies in order to protect themselves against feeding mammals, insects and infection with parasitic fungi. In contrast to plants little is known on the chemical ecology of fruiting bodies of higher fungi, particularly those defence mechanisms which are induced upon wounding have only ...

Chemical Defence in the Termite Ancistrotermes cavithorax
1979Abstract The defensive secretion of the soldiers of the termite Ancistrotermes cavithorax have been shown to consist largely of three new sesquiterpenes. The minor soldiers produce ancistrodial (1) exclusively, whereas the major soldiers secrete ancistrofuran (2) together with a bicyclic unsaturated dialdehyde (3).

Nuclear biological and chemical defence
The RUSI Journal, 1981Summary NBC weapons can all be used in war. Future aggressors may see them as attractive options to be exercised. They could cause mass casualties. Good defensive measures are essential. Only with the ability to protect the service person, reduce potential casualties and give our troops the ability to continue fighting in an NBC environment, will we be

Capsaicin: Tailored Chemical Defence Against Unwanted “Frugivores”
ChemBioChem, 2009AbstractWhy are chilli peppers hot? The vanillyl amide, capsaicin, has long been known as the pungent principle of peppers, but only in their recent work have Tewksbury et al. addressed its ecological roles: to distract unsuitable seed dispensers and to protect the seeds against fungal infection by Fusarium.magnified ...

Biosensors for chemical and biological agents of defence interest
Biosensors and Bioelectronics, 1996This review discusses current developments in biosensors for toxic materials of defence interest with particular emphasis on the biological element of such devices. A wide variety of synthetic chemicals, toxins of plant or animal origin and biological materials--including various disease micro-organisms as well as some bacterial exotoxins--have either ...

Physical versus chemical defence mechanisms in toxic Gastrolobium
Oecologia, 1996The degree to which physical defence mechanisms are present in toxic species of Gastrolobium was compared with the known fluoroacetate (the toxic principle) concentrations of these plants using both histological leaf sections prepared from fresh leaves (4 species), and a variety of visual external traits measured from herbarium specimens (28 species ...

Experimental evidence of chemical defence mechanisms in Antarctic bryozoans
Marine Environmental Research, 2017Bryozoans are among the most abundant and diverse members of the Antarctic benthos, however the role of bioactive metabolites in ecological interactions has been scarcely studied. To extend our knowledge about the chemical ecology of Antarctic bryozoans, crude ether extracts (EE) and butanol extracts (BE) obtained from two Antarctic common species ...
