The Laurentian Great Lakes Basin provides an ecological system to evaluate the potential effect of climate change on dynamics of fish populations and the management of their fisheries. This review describes the physical and biological mechanisms by which fish populations will be affected by changes in timing and duration of ice cover, precipitation events and temperature regimes associated with...

This thesis is composed of three Chapters. Chapter 1 is a preface that outlines the degree program and components of my thesis. Chapter 2 is the main body of the thesis; it is an investigation into pore pressures in the Auger basin and how they are related to fluid venting at the seafloor. I map the distribution of subsurface pressures in thick interconnected sand bodies that are present across...

Ecological succession is one of the most important concepts in ecology. However for microbial community succession, there is a lack of a solid theoretical framework regarding succession in microorganisms. This is in part due to microbial community complexity and plasticity but also because little is known about temporal patterns of microbial community shifts in different kinds of ecosystems, in...

The northern piedmont of the western Kunlun mountains (Xinjiang, China) is marked at its easternmost extremity, south of the Hotan-Qira oases, by a set of normal faults trending N50E for nearly 70 km. Conspicuous on Landsat and SPOT images, these faults follow the southeastern border of a deep flexural basin and may be related to the subsidence of the Tarim platform loaded by the western Kunlun...

Astrocytoma as one of the most common central nervous system (CNS) tumors is rarely reported in veterinary literature. A 7-year-old Persian Lori-Bakhtiari ewe was presented to the clinic with a two months history of progressive blindness, nystagmus to the right, bilaterally decreased pupillary reflexes, head pressing and paddling. At necropsy, a whitish well-circumscribed mass with dimensions o...

It has an area of 16,332 square kilometers and a population of 857,910. To study of human development used the Surplus Biocappacity (SB) and Human Development Index (HDI). This research accrued in the shahr-e-kord, Boroojen, Farsan, Ardal, Lordega...

rainfall is recognized as one of the main triggering factors of landslides. researchers have long attempted to determine the amount of precipitation required to trigger slope failures. one of the landslide zones in iran is chaharmahal & bakhtiari province where many landslides cause high casualties in recent decades. it is significant that most of these landslides occur after a rainy period...
