The campaign of opposition to MX missile deployment in the Great Basin of Nevada and Utah stands as a unique case of grassroots mobilization, because it took place in a region whose inhabitants both supported a strong U.S. military defense posture and considered the decision-making processes of foreign policy and national security remote to their overall concerns. This study holds that the two ...

Accelerated degradation of the wetlands and fragmentation of surrounding vegetation in the Andean-Orinoco Piedmont are the main threats to diversity and ecological integrity of these ecosystems; however, information on this topic is of limited availability. In this region, we evaluated the value of 37 lentic wetlands as reservoirs of woody and aquatic plants and analyzed diversity and changes i...

The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment. Because of the karstic features, the main continental water inflow is from groundwater discharge. The Mar Piccolo basin represents a peculiar and sensitive environment and a social emergency because of sea water and sediment p...

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...

Introduction: Polyorchidism is a rare medical condition, which is presence of more than two testes within the scrotum. Triorchidism is the more common form and the diagnosis is made with ultrasonography. One of the common anomalies associated with polyorchidism is testicular torsion. Case Report: We report a case with four testes and testicular torsion in one testis. Conclusion: Testicular tors...

The general aim of this study, which was conducted for the first time in Iran, was to evaluate the seroprevalence and geographical distribution of Ehrlichia canis in a dog population in Iran, followed by molecular confirmation using PCR and sequencing. Blood samples were collected from 240 dogs in different areas of Alborz and Tehran Provinces and initially analyzed using the immunofluorescent ...

1. introduction nowadays, remote sensing is considered as an important subject in many field studies, like agronomy, hydrogeology, mineral exploration, geography and geology. this knowledge has been applied in most of the geological fields. the significant application of remote sensing is preparation of lineament maps that is an important issue in the geological studies. in the remote sensing s...
