Island rescue
So the tonal distinctions of Chinese syllables, for example, learnt so easily by young native speakers become increasingly difficult to recognise and reproduce for older, foreign learners. But researchers are increasingly finding how able young children are at acquiring more than one language at once. “The important precursor to word learning has led to the assumption that vocabulary acquisitio...
متن کاملThe genetic rescue of two bottlenecked South Island robin populations using translocations of inbred donors.
Populations forced through bottlenecks typically lose genetic variation and exhibit inbreeding depression. 'Genetic rescue' techniques that introduce individuals from outbred populations can be highly effective in reversing the deleterious effects of inbreeding, but have limited application for the majority of endangered species, which survive only in a few bottlenecked populations. We tested t...
متن کاملGenetic rescue to the rescue.
Genetic rescue can increase the fitness of small, imperiled populations via immigration. A suite of studies from the past decade highlights the value of genetic rescue in increasing population fitness. Nonetheless, genetic rescue has not been widely applied to conserve many of the threatened populations that it could benefit. In this review, we highlight recent studies of genetic rescue and pla...

first method, samples are collected and the concentration of DON or individual DON components are monitored over time. To measure DON flux rates using 15N tracer techniques. all of the DIN forms (N~ + , NO3 -.and NO2 -) must be removed, and the DON pool must be isolated with a high efficiency. At present. there are three basic approaches used to isolate DON-wet chemistry, ion retardation, and d...
