The ten lowest ranked concepts (in descending order) for utility were: Lotka-Volterra predator-prey/competition models, Allee effect, nutrient spiraling, character displacement, doubling time, climax, Hardy-Weinberg equation, red queen hypothesis, chemoautotroph/chemoautotrophy, and mimicry. Respondents ...
[29] as “the result of past environmental conditions and subsequent selection on populations [which] is encoded in the current structure of biological communities and reflected in the genetic structure of species”. As an illustrative example, consider the phenomenon of character displacement, [52,...
Displacement is different than the distance traveled. Displacement is found by subtracting the end-point from the start-point. In fact, an object can travel a great distance, yet still have a displacement equal to zero if its final location is the same as its initial location....
In light of all of this, the conclusion has been drawn that the model of the reinforcement of incompatibility in zones of repeated contact with hybridization is not supported by the data, as is the character displacement model that follows from it. The reasons for the popularity of this ...

Although sugar as a nutrient has been a small part of ancestral diets for millennia, the way it is consumed in modern diets is responsible for several adverse health effects, including excess energy consumption, the displacement of nutritious foods, and tooth decay. There is a scientific ...
In the above kind of analysis, man-made desertification or man misuse of land is predominantly attributed to increase in population (see Davies 1984: 135) and not to a political economy that has normalised enforced displacement and overwhelmed the marginal lands. It projects the Nile and the ...
Displacement of populations ADVERTISEMENT Pandemic Emergencies The pandemic is an infectious disease outbreak that has spread to a wide area that can impact the human or animal population and affect health and interrupt services, resulting in economic and social costs. It may be an unexpected rise in...
non-disruptive, more inductive approaches are the only practical alternatives. These alternative approaches usually compare morphology, behaviour, and ecology of two (or more) species which occur under allopatric and sympatric conditions and assume that any niche displacement is directly associated with co...
