Book Synopsis Co-occurring Tree Species Change Rank in Seedling Performance with Small-scale Resource Variation by : Roger Earl Latham
Download or read book Co-occurring Tree Species Change Rank in Seedling Performance with Small-scale Resource Variation written by Roger Earl Latham and published by . This book was released on 1990 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research addressed parallel hypotheses about what maintains tree species diversity in upland, moist-temperate forests: (1) resources are distributed in mesic, upland, temperate forests such that the environment is fine grained for adult trees and coarse grained for seedlings and (2) co-occurring tree species differ in abilities to exploit resources as seedlings, resulting in changes in seedling performance rank by species with small-scale resource variation. Spatial variation in growth rate ranking among species, through competition, may translate into patterns of relative species abundances of tree seedlings that could persist in the community composition of adult trees. Thus, the maintenance of adult tree species diversity may depend on processes occurring at the seeedling stage. Spatial autocorrelation analysis indicates that resources limiting to plant growth in this ecosystem--light, available nitrogen, and soil moisture--are far more patchily and unevenly distributed among growing sites that are the size of small plants, including tree seedlings, than among areas covered by large, adult trees. Greenhouse and forest growth experiments showed that 11 tree species which co-occur as adults in uniform habitat differ in their abilities to exploit resources as seedlings. When ranked by seedling growth characteristics associated with competitive ability, the hierarchy among 9 of the species changed with amounts of resource variation typically found among tree-seedling sized patches on the forest floor and over time. Seedlings of American chestnut, Castanea dentata (Marsh.) Borkh., responded most strongly to resource gradients and ranked highest in traits associated with competitive ability over the broadest range of combinations of resource levels of all species studied. The apparent competitive superiority of chestnut seedlings over a wide range of resource conditions may have contributed to the species' rapid, post-glacial invasion and capture of canopy dominance across a major portion of the eastern North American, moist-temperate forest biome.

Book Synopsis Tropical Forest Census Plots by : Richard Condit
Download or read book Tropical Forest Census Plots written by Richard Condit and published by Springer Science & Business Media. This book was released on 1998-06-26 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: By way of a summary of all the data collected by the mapping teams, I will review what is entered on each of the data sheets. The map sheet was already de scribed in some detail (Fig. 2.2.1A), and includes a circle or a point for the location of each tree and the tree's tag number (the last three or four digits) written next to it. The range of tag numbers used in the quadrat should be written at the top of the sheet. The main data sheet is where most other information about each individual is recorded (Fig. 2.2.1B). As for all sheets, the quadrat number, the first date a quadrat is censused, and the mappers' names are recorded at the top. For each plant, there are blanks for the following information: subquadrat number, tag number, species name, dbh, codes, and problems. Subquadrat number and tag number are straight forward. Size in millimeters is entered in the dbh column, except for multiple stemmed plants or big trees, which get a blank dbh on the main data sheet. Species identification will be handled by separate taxonomy teams (chapter 2.3), but map pers should enter a species name if they know it.
Book Synopsis Alpine Treelines by : Christian Körner
Download or read book Alpine Treelines written by Christian Körner and published by Springer Science & Business Media. This book was released on 2012-05-26 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpine treelines mark the low-temperature limit of tree growth and occur in mountains world-wide. Presenting a companion to his book Alpine Plant Life, Christian Körner provides a global synthesis of the treeline phenomenon from sub-arctic to equatorial latitudes and a functional explanation based on the biology of trees. The comprehensive text approaches the subject in a multi-disciplinary way by exploring forest patterns at the edge of tree life, tree morphology, anatomy, climatology and, based on this, modelling treeline position, describing reproduction and population processes, development, phenology, evolutionary aspects, as well as summarizing evidence on the physiology of carbon, water and nutrient relations, and stress physiology. It closes with an account on treelines in the past (palaeo-ecology) and a section on global change effects on treelines, now and in the future. With more than 100 illustrations, many of them in colour, the book shows alpine treelines from around the globe and offers a wealth of scientific information in the form of diagrams and tables.

Book Synopsis Rainforest Ecosystems of East Kalimantan by : Edi Guhardja
Download or read book Rainforest Ecosystems of East Kalimantan written by Edi Guhardja and published by Springer Science & Business Media. This book was released on 2000 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the late 1960s the Indonesian state of East Kalimantan has witnessed a marked increase in the impact of human activities chiefly commercial logging and agricultural exploitation. Located on the island of Borneo, East Kalimantan also was subjected to prolonged droughts and extensive wildfires in 1982-83 and 1997-98 that were linked to the El Nino-Southern Oscillation (ENSO) phenomenon. The changes in the rainforest ecosystem in East Kalimantan during this 15-year cycle of severe ENSO events are the subject of this book. With an eye toward development of rehabilitation techniques for sustainable forest management, the authors examine possible interactive effects of drought, fire, and human impacts on the flora and fauna of the area.
