Non-lethal effects of predation risks Non-lethal effects of predation in birds

Predators can affect individual fitness and population and community processes through lethal effects (direct consumption or ‘density’ effects), where prey is consumed, or through non-lethal effects (trait-mediated effects or interactions), where behavioural compensation to predation risk occurs, such as animals avoiding areas of high predation risk. Studies of invertebrates, fish and amphibian...

Time delay in non-lethal infectious diseases

The effects of the incubation period q on the dynamics of non-lethal infectious diseases in a fixed-size population are studied by means of a delay differential equation model. It is noted that the ratio between the quantity q and the time τ for recovering from the illness plays an important role in the onset of the epidemic breakthrough. An approximate analytic expression for the solution of t...

Non-lethal Alternatives for Predation Management

Non-lethal PCR genotyping of single Drosophila.

In Drosophila, genetic techniques relying on stochastic chromosomal rearrangements involve the generation and screening of a large number of fly stocks to isolate a few lines of interest. Here, we describe a PCR-based method allowing non-lethal molecular characterization of single flies. Using this procedure, individual candidate recombinant animals can be genotyped and selected one generation ...

Non-Lethal Weapons: Striking Experiences in a Non-Cooperative Environment

In missions to stabilize conflicts around the world, the military forces increasingly find themselves operating amongst the people. The emerging need in military interventions to prevent casualties translated into a range of value driven military technological developments, such as non-lethal weapons (NLW). NLWs can be characterized by a certain technological and operational design ’window’ of ...
