Species with a chemical defence, but not chemical offence, live longer [PDF]
Journal of Evolutionary Biology, 2013 AbstractEvolutionary hypotheses for ageing generally predict that delayed senescence should evolve in organisms that experience lower extrinsic mortality. Thus, one might expect species that are highly toxic or venomous (i.e. chemically protected) will have longer lifespans than related species that are not likewise protected.

Deterrent activities in the crude lipophilic fractions of Antarctic benthic organisms: chemical defences against keystone predators [PDF]
Polar Research, 2014 Generalist predation constitutes a driving force for the evolution of chemical defences. In the Antarctic benthos, asteroids and omnivore amphipods are keystone opportunistic predators.

Defence Technology, 2022 All underwater drilling and blasting operations generate seismic waves. However, due to a lack of suitable vibration sensing instruments, most studies on the propagation of seismic waves have been limited to shorelines near construction areas or wharfs ...

Chemical Defence and Toxins of Plants [PDF]
, 2010 Higher plants protect themselves by producing a variety of secondary metabolites and proteins that are involved in defense against herbivores as well as microbial pathogens. Concerning microbial pathogenesis in plants, in many cases, it is known that phytotoxins that are produced by plant pathogens play an important role in disease development causing ...

Predator‐induced changes in the chemical defence of a vertebrate [PDF]
Journal of Animal Ecology, 2019 Abstract1. Inducible defences are ubiquitous in the animal kingdom, but little is known about facultative changes in chemical defences in response to predators, especially so in vertebrates.2. We tested for predator‐induced changes in toxin production of larval common toads (Bufo bufo), which are known to synthesize bufadienolide compounds.3.

Inducible chemical defences in animals [PDF]
Oikos, 2014 Phenotypic plasticity is extremely widespread in the behaviour, morphology and life‐history of animals. However, inducible changes in the production of defensive chemicals are described mostly in plants and surprisingly little is known about similar plasticity in chemical defences of animals. Inducible chemical defences may be common in animals because

Organization and Concept of Intervention of the Chemical Defence Bases in Switzerland
CHIMIA, 2004 In contrast to radiological risks, which are the responsibility of the federal authorities, the cantons have to deal with chemical risks. In agreement with the chemical defence concept of the Swiss Fire Fighters Association (SFFA) each canton ...
