Ecological Significance of Resistance to High Temperature [PDF]
, 1981 Heat as a stress factor limiting the survival of plants has been recognized for some time, and reports about plants in hot environments were already critically discussed by Sachs (1864). At first plant response to heat was treated as a physiological problem (Bělehradek 1935, and cf. Chap. 12, this Vol.).

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 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 ...

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.

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.

Resistance and Pathogenicity: Epidemiological and Ecological Mechanisms
1985Resistance in host plants and pathogenicity in the organisms causing disease are inseparable and defining attributes of the disease interaction. These matching attributes have been intensively studied in two major contexts: to meet the often pragmatic needs of plant breeders; and to understand the host-pathogen relationship, perhaps the most subtle and

Ecological Sensitivity and Resistance of Cultures in Asia
Behavior Science Research, 1978Ecological influences on culture have been demonstrated by several in vestigators. Many such studies have been done in Asia where two ecological niches extend over vast areas. One of these is the highland or mountainous territory 500 meters above sea level; the other consists of plains and pla teaus under 500 meters.

Ecocriticism and Italy: Ecology, Resistance, and Liberation
Green Letters, 2018In this impressive new book, Serenella Iovino sets out to read the ‘landscapes and more-than-human collectives’ of Italy as ‘texts bearing material stories – stories of resistance and creativity’ t...

Ecological Significance of Resistance to Low Temperature
1981Low temperatures reduce the biosynthetic activity of plants; they evoke disturbance in vital functions and productivity and they may inflict permanent injuries that finally bring about death. The survival capacity of a plant species or variety in a particular environment is determined by the specific limits to which its metabolic processes continue to ...

Ecological resistance and buffers of environmental change
2016The development of frameworks that account for community stability and its loss to environmental disturbance (e.g. regime shifts) is central to ecology, particularly for reducing uncertainty of ecological change in increasingly variable environments. Notably, community responses to disturbance often appear abrupt and surprising, raising concerns for ...
