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...

BACKGROUND Previous studies have revealed significant differences between populations for genotypic frequencies of glutathione S-transferase T1 (GSTT1) and M1 (GSTM1) polymorphisms. In order to find the frequency of the null genotypes of GSTM1 and GSTT1 in Iranian populations, the present study was carried out. METHODS The total study subjects consisted of 1340 unrelated healthy Muslims/Irani...

abstract among different water usage in iran, agricultural sector with 94 percent is the largest water user. considering the share of agriculture in water usage, farmers are the main factor in water resources management. therefore, optimal utilization of irrigation and drainage networks would depend on farmers’ effective role. due to the limited water resources in different country regions, inc...

Introduction: There is a high prevalence of hemoglobinopathies, including thalassemia, in Sistan and Baluchistan province Iran. It important to appropriately screen young adults control the birth new cases thalassemia. In many less-equipped centers, this practice only relies on cell blood count. This study investigated hematological parameters referring Central Laboratory Sistan, Zabol, for pre...
