Mineralogy and stratigraphy of the pre-Berea sedimentary rocks exposed in northern Ohio by Bruce W Nelson( )

4 editions published in 1955 in English and held by 11 WorldCat member libraries worldwide

Argillaceous sedimentary rocks are the most common products formed during the erosion of a landmass. They cover more than half the continental areas, and they are the most abundant rocks. Even so, they are the most neglected and mineralogically least understood of all rocks with which the petrologist must deal. Their petrography is known only in the most general way. The underlying objective of this thesis, therefore, is to describe a group of rocks from northern Ohio that consist almost exclusively of highly argillaceous shales and siltstones. The description and interpretation of such rocks has been made possible recently by advances in technique and knowledge in the field of clay mineralogy

Allometric regressions for improved estimate of secondary forest biomass in the central Amazon by Bruce W Nelson( )

2 editions published in 1999 in English and held by 2 WorldCat member libraries worldwide

Estimates of the sequestering of carbon by secondary of forests - wich occupy almost half the deforested area of the Brazilian Amazon - will be improved by the use of accurate allometric relationships for non-destructive measurement of standing biomass and by an evaluation of the suitability of existing equations for application in secondary forest. Species-specific and mixed-species regressions for estimating total above-ground dry weight (DW) were therefore developed using eight abundant secondary forest tree species in the central Amazon. Using only DBH as the input variable, the species-specific equations estimated DW of individual trees an average error of 10%-15%. For the mixed-species equations, developed using 132trees from seven of the wight species (excluding Cecropia, average error in estimating DW of individual trees was 19.8% using only DBH and 15.0% using DBH plus specific density of the wood (SD). Average SD for each species can be substituted without increasing the error of the estimate. Adding total tree hight (H) as an input variable provided only a slight reduction in error to 14.0%. Previously plublished mixed-species biomass regression models, based on primary and secondary forest trees of the Amazon, were also cross-valited against the trees of this study. Two of these models, based on primary forest plots and using only DBH as an input, overstimated biomass by 10%-60% for central Amazonian secondary of forest trees in the size range 5cm-25cm. The overstimate was greatest for the larger trees. Including Cecropia in the test group will make the overstimate even greater. Those published equation using DBH, H. and SD as inputs, wheter from secondary or primary forest plots, showed better agreement with the sample-derived regressions and lower average erros in estimation of individual tree dry weights

Repeated fires trap Amazonian blackwater floodplains in an open vegetation state( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Climate change may increase the occurrence of droughts and fires in the Amazon. Most of our understanding on how fire affects tropical ecosystems is based on studies of non-flooded forest-savanna ecotones. Nonetheless, tropical floodplain forests in the Amazon can burn severely during extreme droughts. The mechanisms slowing down forest regeneration in these ecosystems remain poorly understood and have never been assessed in the field. We studied the recovery of Amazonian blackwater floodplain forests after one and two fire events. We used Landsat images to map fire history and conducted field surveys to measure forest structure, tree species richness, tree seed bank and post-fire invasion of herbaceous plants. Sites burnt once had on average 0% trees, 6% tree seed abundance, 23% tree seed species richness and 8% root mat thickness compared to unburnt forests. In contrast, herbaceous cover increased from 0 to 72%. Nonetheless, forest structure and diversity recovered slowly towards pre-burn levels, except for tree seed banks that remained depleted even 15 years after fire. Sites burnt twice had on average 0% trees, 1% tree seed abundance, 3% tree seed species richness and 1% root mat thickness compared to unburnt forests. Herbaceous cover increased to 100%. Mean recovery of tree basal area was 50% slower and of root mat thickness 93% slower compared to recovery in sites burnt once. Tree seed banks did not recover at all, and herbaceous cover persisted close to 100% for more than 20 years after the second fire. Synthesis and applications . Our results indicate that after a second fire event, Amazonian blackwater floodplain forests lose their recovery capacity, and persist in a non-forested state dominated by herbaceous vegetation. Such fragility implies that preventing human ignited fires during drought episodes is a particularly important conservation strategy for these ecosystems.
