بذه عن الكتاب:
• The terms ‘weed’, ‘invader’, ‘colonist’, ‘exotic’, ‘non-native’ and others are often used in
overlapping and conflicting manners.
• Weeds are classified based on their impact on human activities. Therefore, the effect of
a weed is difficult to quantify because it depends on our personal biases.
• Definitions and classifications in ecology are often arbitrary and made for purely practical reasons. They do not necessarily reflect any innate structure of nature.
• Ecology can be studied at a variety of levels. In this book, we focus on population and
community ecology.
• Weed ecology provides a basic understanding of the distribution and abundance of
weeds in natural and managed systems. In the long term, it may change our attitudes and
perceptions towards weeds and alter the way we manage them.
