The tropical mountain forest : patterns and processes in a biodiversity hotspot by S. R Gradstein( )

11 editions published between 2008 and 2014 in English and held by 1,228 WorldCat member libraries worldwide

Tropical mountain forests are very rich in species and are generally considered as hotspots of biodiversity. They are also of great ecological importance as sources of water and other ecosystem services for millions of people living in the tropics. However, these valuable forest ecosystems are now increasingly being fragmented, reduced and disturbed by human interventions. This book originated from a lecture series on the tropical mountain forest organized by the Gottingen Centre of Biodiversity and Ecology and held at the University of Gottingen, Germany during the summer term of 2007. The volume presents a synthesis of current ecological research in Germany on the tropical mountain forest, from an interdisciplinary perspective
Vegetation, climate and environmental dynamics of the Black Sea/Northern Anatolian region during the last 134 ka obtained from palynological analysis by Lyudmila Shumilovskikh( )

1 edition published in 2013 in English and held by 30 WorldCat member libraries worldwide

As a part of the multidisciplinary project "Dynamics of Mid-latitude/Mediterranean climate in Northern Anatolia/Black Sea region during the last 150 kyr", this research presents new pollen and organic-walled dinoflagellate cyst records from the SE Black Sea for the penultimate deglaciation - Eemian (134-119 ka), last glacial (64-23 ka) and last deglaciation - Holocene (18 ka - present) periods. The reconstruction is based on the records from the sediment cores 22-GC3, 22-GC8 and 25-GC1, and provides information on vegetation successions in Northern Anatolia and on changes in the Black Sea s
The rhizosphere effects of Fagus sylvatica L. and Fraxinus excelsior L. saplings on greenhouse gas fluxes between soil and atmosphere by Ann-Catrin Fender( )

2 editions published in 2012 in English and held by 30 WorldCat member libraries worldwide

Tree species influence the soil through stemflow and throughfall water, leaf litter and the root system. Little is known about the effects of tree roots on the C and N dynamics of the soil and the gas exchange with the atmosphere. In the present study, the effects of European beech (Fagus sylvatica) and Common ash (Fraxinus excelsior L.) saplings, as important European broad-leaved tree species, on C and N fluxes in the soil of a species-rich temperate forest were investigated under constant climatic conditions. The main objective was to identify root-induced changes in the greenhouse gas f
Effects of earthworms and tree species (Fagus sylvatica L., Fraxinus excelsior L.) on greenhouse trace gas fluxes in mixed deciduous broad-leaved forests by Klaus Schützenmeister( )

2 editions published between 2014 and 2015 in English and held by 19 WorldCat member libraries worldwide

Despite the large number of studies and the associated knowledge gain uncertainties on the determinants of greenhouse gas fluxes from terrestrial ecosystems still exist. It is important to bridge these gaps as land use and particularly land use change as the important driver of the feedback loops between the atmosphere and the land surface. One major process is the direct emission of greenhouse gases as land use and land use change is ranking second behind burning of fossil fuels. During the past decades, global land-use and land-cover changed dramatically and thus, the biogeochemical inter
Development and dynamics of the Atlantic rainforest during the Late Quaternary and its connections with the climate system by Jackson Martins Rodrigues( )

2 editions published in 2016 in English and held by 18 WorldCat member libraries worldwide

The Atlantic rainforest harbour an outstandingly high biodiversirty. Many different environmental factors (climate, soil, geomorphology, ocean and etc) interact in a very large space creating complex ecosystems with high endemism. Altough, its richness, the Altnatic rainforest is highly endangered due to increasing human impact through the intensification of land-use and consequent broad landscape replacement. Many palaecological studies have been developed during the last decades providing important background of diverse location around Atlantic rainforest, however little is known about re
Pollination ecology and spatial genetic population structure of wild and cultivated species of cacao (Theobroma) in Bolivia by Claudia Chumacero de Schawe( )

1 edition published in 2014 in English and held by 17 WorldCat member libraries worldwide

Tropical forest in southwestern Amazonia is threatened by increasing human populations, economic exploitation, deforestation and burning activities for cattle raising and agriculture. Tropical rainforests are characterized by a high level of tree species diversity and consequently low population densities and large distances among conspecifics. The spatial distribution of individuals has substantial consequences for the movement of their pollinators and intraspecific gene flow, hence affecting sexual reproduction. Thus knowledge of gene flow is elementary for understanding the reproductive
Definition of areas with high conservation priority in Southern Ecuador - An approach combining spatial and temporal patterns of deforestation and human impact with endemic plant diversity by María Fernanda Tapia Armijos( )

3 editions published between 2015 and 2016 in English and held by 17 WorldCat member libraries worldwide

The forests of South Ecuador have high conservation value because they are highly threatened, but also possess high diversity and endemism levels. However, as the process of conservation is inherently spatial, the little available information about the factors that promote vulnerability of these forests as well as the spatial distribution of the conservation targets have produced some conservation pitfalls. The main objective of this dissertation was to generate spatial information about the threats and biological values occurring in this region to prioritize areas for conservation. The sec

Studies on mountain vegetation, plant diversity, fire and forest line dynamics of the Southeastern and Central Ecuadorian Andes during the Late Quaternary by Andrea Soledad Villota Villafuerte( )

2 editions published between 2014 and 2015 in English and held by 17 WorldCat member libraries worldwide

The Ecuadorian Andes in northwestern South America are well known for being among the hot spots of global vascular plant diversity due to their complex topography (uplift of the mountain chain), varying climatic conditions and different vegetation types. Despite its high biodiversity level, the Ecuadorian Andes represent a most threatened and poorly studied landscape. Especially the páramo and mountain ecosystems are subject to overgrazing, burning, cultivation and deforestation caused by the expansion of human activity during the last decades. The knowledge of palaeoecology and landscape d

Origin and regulation of soil N2O and NOx fluxes from coniferous and deciduous temperate forests exposed to chronic high N depositions by Nadine Eickenscheidt( )

1 edition published in 2012 in English and held by 13 WorldCat member libraries worldwide

Nitrogen (N) cycling in Europe and in many other parts of the world has been massively accelerated as a result of agricultural and industrial activities in the last decades. As a consequence, forest ecosystems have been exposed to increasing deposition rates of reactive N, which may increase soil N availability. Increased N availability in turn may alter nitrous oxide (N2O) and nitric oxide (NO) emissions, which play a major role in atmospheric chemistry and contribute to global warming. Several studies reported that European temperate forests receiving chronic high N depositions are important sources for N2O and NO. Despite high research efforts in the last two decades, there is still insufficient knowledge about the importance of N depositions and forest type on N oxide fluxes from temperate forest soils. Therefore, the objectives of the present study were (i) to investigate the origin of N oxide emissions from temperate forest soils exposed to chronic high N depositions and to quantify the contribution of N depositions and turnover of leaf litter N to N2O emissions and (ii) to determine the factors that regulate N oxide fluxes in temperate forest soils with special regard to the impact of forest type and soil gas diffusivity
Variability of physiological traits and growth performance in aspen assemblages differing in genetic relatedness = Variabilität physiologischer Parameter und Wachstum von Aspen mit unterschiedlicher genetischer Herkunft by Annika Müller( )

1 edition published in 2011 in English and held by 13 WorldCat member libraries worldwide

Due to the increasing demand for wood and renewable energy sources, short-rotation forestry with its reliance on highly productive Populus species is in the focus of current ecological research. In order to optimize biomass gain, Populus research has in recent decades mainly centred on productivity and related traits for poplar species which could be proven to be highyielding. Aspen (Populus tremula and Populus tremuloides), however, have for a long time been neglected, because their highest annual increment occurs later than for e.g. black poplar and balsam poplar and they therefore need longer rotation times. However, in this thesis we concentrated on aspen (P. tremula and P. tremuloides) as study objects because they cope better with drought on poor soils and have the lowest demand regarding habitat conditions when compared to other poplar species. These features make aspen a promising alternative for short-rotation forestry in the face of the future climate scenarios, which include increasing temperatures and decreasing summer precipitation. Therefore, we established a common-garden experiment in 2008 with closely related aspen full-sib families (P. tremula: 2-30% genetic distance) as study objects. In the subsequent year, we established a field experiment with more distantly related aspen collectives (P. tremula: 20-40% genetic distance) originating from Central Europe as well as two different aspen species (P. tremula with German origin and P. tremuloides with American background differing 77% in their genetic distance) as study objects

Vegetation, climate and fire dynamics of Upper Montane Forest and Campos de Altitude during the Holocene in southeastern Brazil by Maria Carolina Guarinello de Oliveira Portes( )

2 editions published in 2020 in English and held by 4 WorldCat member libraries worldwide

The Atlantic Forest biome is well known as one of the mostly biodiversity regions on earth, hosting high species endemism and species/area ratio. It stretches around 1,300,000 km2 along the Brazilian coast between latitudes 3º and 33º S and longitudes 35º and 57º E. Due to the increase of human impact through the intensification of land-use and consequent broad landscape replacement along the centuries, only 10-15% of the Atlantic Forest biome remains in a natural or semi-natural state, being considered one of the most priority areas for conservation. It encompasses a wide variation of clim
Studies on vegetation-, fire-, climate- and human history in the mid- to late Holocene - a contribution to protection and management of the forest-steppe-biome in the Mongolian Altai by Julia Unkelbach( )

2 editions published in 2020 in English and held by 4 WorldCat member libraries worldwide

In this thesis, several sedimentological archives from Altai Tavan Bogd National Park are studied to reconstruct the vegetation-, fire-, climate- and human history of the forest-steppe biome in the Mongolian Altai. The research is carried out to improve the understanding of the dynamics and variability of this sensitive ecosystem and its unique biodiversity. Previous palynological or palaeoecological work from the Mongolian Altai is sparse, yet important for an implementation of sustainable land use as well as protection and management of the species-rich vegetation in the Altai region.
