Upper Triassic Palaeobotany of Biobío river valley, Chile: Filicopsida Class.

Lifelines Performance of the Mw 8.8 Offshore BIOBÍO,Chile Earthquake

The paper will provide a summary of all lifelines performance in this strong earthquake. The paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. The impact as a result of the lifelines service interruption will be discussed; most important is the ...

Paternity Outcomes in the Freshwater Gastropod, Chilina dombeiana in the Biobío River, Chile

Studying the mating system of obligate aquatic organisms that inhabit river ecosystems is important for understanding its evolution as well as the role of biological and environmental factors in modulating population dynamics and species distributional patterns. Here, we studied the reproductive strategy of the Chilean endemic freshwater snail, Chilina dombeiana, in the Biobío River, one of the...

Character and History of the Upper Ohio River Valley

Dismemberment of the preglacial Teays Valley system and development of the present Ohio River valley began in late Tertiary or early Pleistocene. By Illinoian time the present Ohio River was largely established in its present course, except for its headwaters above mile 114, which still flowed northward. The Illinoian glacial advance into northwestern Pennsylvania caused diversion of this porti...
