The world is becoming an increasingly urban planet with 68% of the global population expected to live in cities by 2050 and urban land cover expected to increase by 40%. This urban expansion brings with it a host of environmental and health consequences such as the urban heat is…
Em 2016, as áreas florestais baldias celebraram 40 anos de gestão comunitária. Estas, na sua maioria, foram plantadas durante a ocupação dos terrenos comunitários (vulgo baldios) pelo Estado Novo e durante o desenvolvimento do Regime Florestal através do Plano de Povoamento Flor…
Disturbance gaps in forests stimulate tree regeneration, maintain biodiversity, and promote forest heterogeneity. In urbanized regions, long term forest sustainability is threatened by many ecological stressors, such as high deer pressure and invasive plant spread, which can aff…
Coastal wetlands across the Southeastern U.S. coastline are among the most productive ecosystems worldwide, but are expected to experience challenges due to human alterations of the landscape, sea-level rise, and changing frequency of extreme events. Wetlands provide critical ec…
Epigeal predatory arthropods were collected with pitfall-style traps in nine sandstone glades of varying ecological stages, and management histories, in the Ozarks of Northern Arkansas over three years. These sites were categorized into three Site Types; Intact, high quality gla…
Logging has been hypothesized to have long-term effects on plant communities throughout the world. Quantifying the effects of disturbances such as logging on patterns of plant diversity and composition is a fundamental question in ecology and conservation. In this dissertation I…
The present investigation, is born from the necessity of preserving Madeira island’s craftsmanship, their technics and products, from Madeiran Embroidery, Wicker, Wood Inlays, “Palmito” and “Canavieira”. This work was elaborated to present these crafts that still deserve attenti…
The balsam woolly adelgid (BWA) is a tiny, piercing-sucking insect that was introduced into North America around 1900 and into the Southern Appalachians in the 1950s. It is a major pest in natural Fraser fir stands and Christmas tree plantations. It has caused extensive mortalit…
In the last two decades, many firms in the U.S. forest products industry have either divested their timberlands or converted their corporate structures from C corporations to real estate investment trusts (REITs). This study hypothesizes that this large-scale timberland ownershi…
Nature reserves are increasing in number worldwide, but they are often fragmented, small, and poorly managed. Land uses contrasting strongly with reserves may reduce their effective size. Complex agroforests and mature plantations, however, may extend forest functions beyond par…
The primary objective of this study was to describe the variability in site productivity of the diverse forests found in the state of Jalisco, Mexico. This information is fundamental for the management and sustainability of the species-rich forests in the state. The study also c…
Tree-ring records collected from living mountain hemlock trees in the southern British Columbia Coast Mountains have been used to provide insights into the character of historical climatic fluctuations and the behaviour of individual climate forcing mechanisms. The relatively sh…
Northern peatlands have accumulated approximately one third of all soil carbon (C) and therefore play an important role in the global C cycle. Besides the C sink function, peatlands are one of the largest biological sources of atmospheric methane (CH4) and represent approximatel…
This research investigates the potential socio-cultural impacts that might result from an agroforestry improvement project in two study communities of Narsingdi District, Bangladesh. A range of qualitative research methods are employed for the investigation. Results reveal that …
Powder fuel quality and behavior for thermal conversion systems are investigated by assessing the combustion reactivity using thermogravimetric analysis (TGA). The aim is to obtain the kinetic and pyrolytic characteristics of powder fuel from forestry residue (white spruce, whit…
The ambermarked birch leafminer (AMBLM) (Profenusa thomsoni) is an invasive leafminer native to the Palearctic from the United Kingdom to Turkey to Japan. It was introduced to the eastern United States in 1921 and has since spread to the mid-western U.S. states and Canadian prov…
Industrial scientific forestry has been one of the main tools of state control over land and forest resources in post-colonial Indonesia, particularly since the beginning of the New Order era inaugurated by the military coup of General Suharto in 1966. Suharto's regime facilitat…
This research attempts to identify a number of socio-economic factors that are important in determining the success of afforestation programs to combat desertification in Northern Nigeria. Issues investigated included the quality and quantity of extension services, the role of i…
