The evolutionary ecology of insect resistance to plant chemicals
Trends in Ecology & Evolution, 2007Understanding the diversity of insect responses to chemical pressures (e.g. plant allelochemicals and pesticides) in their local ecological context represents a key challenge in developing durable pest control strategies. To what extent do the resistance mechanisms evolved by insects to deal with the chemical defences of plants differ from those that ...

Organisational resistance to ecological footprinting
International Journal of Management Concepts and Philosophy, 2009This paper explores organisational resistance to more comprehensive sustainability reporting in the form of ecological footprinting. On the basis of a series of interviews with Corporate Social Responsibility (CSR) Managers in the UK, a number of barriers were identified for ecological footprinting at the organisational level: the cost and resource ...

1997
This paper begins an inquiry into the subject of resistance. In diffusion theory and in the related field of organizational development, resistance is overdetermined. In other words, the topic is typically glossed and is too easily identified as an automatic, and by nature negative, response to change: a change that is to be managed.

Antibiotic resistance: an ecological imbalance.
Ciba Foundation symposium, 1997Antibiotic resistance thwarts the treatment of infectious diseases worldwide. Although a number of factors can be identified which contribute to the problem, clearly the antibiotic as a selective agent and the resistance gene as the vehicle of resistance are the two most important, making up a 'drug resistance equation'.

Direct and ecological costs of resistance to herbivory
Trends in Ecology & Evolution, 2002Herbivores can consume significant amounts of plant biomass in many environments. Yet plants are not defenseless against such attack. Although defenses might benefit plants in the presence of herbivores, herbivore attack varies both spatially and temporally, and the expression of plant resistance to herbivores can be costly in the absence of plant ...

Economic and Ecological Values of Resistant Plants
2019As a sole method, resistant cultivars help keep the population of key pests under check. Resistant cultivars under field conditions can obviate the need for application of insecticides. Resistant cultivars can well combine with natural enemies, cultural practices, mechanical and physical devices/barriers, microbial, insecticides, and molecular and ...

Unravelling the Ecology of Antibiotic Resistant Bacteria in the Nasopharynx
2010To study the dynamics and diversity of pneumococcal carriage and antibiotic resistance, a more thorough and systematic approach has been employed compared with routine surveillance of serotype and anti-biotic resistance. Up to ten pneumococcal isolates from pernasal (nose) and oropharyngeal (throat) sites are isolated and characterised.

The ecology of mercury-resistant bacteria in Chesapeake Bay
Microbial Ecology, 1974Total ambient mercury concentrations and numbers of mercury resistant, aerobic heterotrophic bacteria at six locations in Chesapeake Bay were monitored over a 17 month period. Mercury resistance expressed as the proportion of the total, viable, aerobic, heterotrophic bacterial population reached a reproducible maximum in spring and was positively ...

The ecology and evolution of host-plant resistance to insects
Trends in Ecology & Evolution, 1990Genetic techniques have yielded new insights into plant-herbivore coevolution. Quantitative genetic tests of herbivory theory reveal that in some cases insect herbivores impose selection on resistance traits. Also, some resistance traits are costly while others appear not to be, and genetic models can explain these results.
