Chemotherapy of venereal diseases: its uses and abuses.
For centuries the man of medicine practised the relief of symptoms, his power to influence the processes of disease being strictly limited; the art of medicine was largely confined to providing circumstances favourable for the vis medicatrix naturae to function to the best advantage. When, however, Pasteur, Lister, and Koch turned the spot-light of science on the bacterial battlefield, knowledg...
متن کاملPlant invasions, generalist herbivores, and novel defense weapons.
One commonly accepted mechanism for biological invasions is that species, after introduction to a new region, leave behind their natural enemies and therefore increase in distribution and abundance. However, which enemies are escaped remains unclear. Escape from specialist invertebrate herbivores has been examined in detail, but despite the profound effects of generalist herbivores in natural c...
متن کاملIntegrating novel chemical weapons and evolutionarily increased competitive ability in success of a tropical invader.
The evolution of increased competitive ability (EICA) hypothesis and the novel weapons hypothesis (NWH) are two non-mutually exclusive mechanisms for exotic plant invasions, but few studies have simultaneously tested these hypotheses. Here we aimed to integrate them in the context of Chromolaena odorata invasion. We conducted two common garden experiments in order to test the EICA hypothesis, a...
متن کاملEcosmart Biorational Insecticides: Alternative Insect Control Strategies
Pest insects can damage agricultural crops, consume and/or damage harvested food, or transmit diseases to humans and animals. The past 30 years has witnessed a dramatic reemergence of epidemic vector-borne diseases throughout much of the world (Atkinson, 2010). Prior to the development and commercial success of synthetic insecticides in the mid1930s to 1950s, botanical insecticides were the for...
متن کاملPathogens as Biological Weapons of Invasive Species
Invasive species are nonindigenous species that are introduced into new environments, where they become established and expand their range [1]. They undergo rapid proliferation following the colonization of new habitats, often at the expense of native species, thus having a negative impact on biodiversity. The prospering discipline of invasion ecology seeks to understand why some species become...
