Island Colonization: The Origin and Development of Island CommunitiesNew or recently sterilized islands (for example through volcanic activity), provide ecologists with natural experiments in which to study colonization, development and establishment of new biological communities. Studies carried out on islands like this have provided answers to fundamental questions as to what general principles are involved in the ecology of communities and what processes underlie and maintain the basic structure of ecosystems. These studies are vital for conservation biology, especially when evolutionary processes need to be maintained in systems in order to maintain biodiversity. The major themes are how animal and plant communities establish, particularly on 'new land' or following extirpations by volcanic activity. This book comprises a broad review of island colonization, bringing together succession models and general principles, case studies with which Professor Ian Thornton was intimately involved, and a synthesis of ideas, concluding with a look to the future for similar studies. |

Side 102 - The Island all Night vomited Fire and Smoak very amazingly ; and at every Belch we heard a dreadful Noise like Thunder, and saw a Flame of Fire after it, the most terrifying that ever I saw.
Side 102 - Smoak very amazingly ; and at every Belch we heard a dreadful Noise like Thunder, and saw a Flame of Fire after it, the most terrifying that ever I saw. The Intervals between its Belches, were about half a Minute ; some more, others less : Neither were these Pulses or Eruptions alike ; for some were but faint Convulsions, in Comparison of the more vigorous; yet even the weakest vented a great deal of Fire ; but the largest made a roaring Noise, and sent up a large Flame...
Side 102 - I saw a great Fire bearing NorthWest by West, blazing up in a Pillar, sometimes very high for 3 or 4 Minutes, then falling quite down for an equal Space of Time ; sometimes hardly visible, till it blazed up again.
Side 102 - ... matter thrown out of the funnel at the top, which tumbling down to the bottom, and there lying in a heap, burned till either consumed or extinguished; and as long as it burned and kept its heat, so long the...
Side 102 - I knew it to be a burning hill by its intervals. The island all night vomited fire and smoak [sic] very amazingly, and at every belch we heard a frightful noise like thunder, and saw a flame of fire after it, the most terrifying I ever saw. The intervals between its belches were about half a minute, some more some less . . . the largest made a roaring noise and sent up flame twenty or thirty yards high; and then might be seen a great stream of fire running down to the foot of the island, even to...
