Effects Of Distance To Juniperus Virginiana On The Establishment Of Fraxinus And Acer Seedlings In Old Fields, Scott J. Meiners, David L. Gorchov
Effects Of Distance To Juniperus Virginiana On The Establishment Of Fraxinus And Acer Seedlings In Old Fields, Scott J. Meiners, David L. Gorchov
Scott J. Meiners
It has been hypothesized that Juniperus virginiana facilitates tree seedling establishment in secondary succession. To test this hypothesis, we sampled four old fields in southwestern Ohio and monitored experimentally planted seeds and seedlings of Acer saccharum and Fraxinus americana for two years. Seeds and seedlings were placed into herbivore exclosures placed 0.3 and 3.0 m from J virginiana trees in an old field in Ohio. We found a significant positive spatial association between juniperus virginiana and tree seedling densities in all four old fields. Soil temperature, soil moisture, evaporative demand and light level in the 0.3 m treatment were significantly …

Reproductive Demographics And Early Life History Of The Shovelnose Sturgeon (Scaphirhynchus Platorynchus), Robert E. Colombo
Reproductive Demographics And Early Life History Of The Shovelnose Sturgeon (Scaphirhynchus Platorynchus), Robert E. Colombo
Robert E. Colombo
Due to the collapse of the historic caviar fisheries in the Volga River and Caspian Sea, the demand on domestically produced caviar has increased. To supply the increased demand, the harvest of the shovelnose sturgeon Scaphirhynchus latorynchus has increased. Because caviar fisheries preferentially harvest females, information regardingthe sexual demographics of these populations is essential for effective fisheries management. To date, knowledge regarding the sex ratios and reproductive development of the shovelnose sturgeon population in the Middle Mississippi River is lacking. In Chapter 1, I describe this problem in detail and in subsequent chapters I explain how I addressed this problem …

Horizontal starch gel electrophoresis was used to assess variability at 23 presumptive gene loci of 732 river otters obtained from fur-trappers in 18 states and three Canadian provinces. States and provinces providing otters were sorted into eight geographic regions for genetic comparisons. Multilocus heterozygosity and polymorphism ranged from 0.018 to 0.032 and 0.044 to 0.087, respectively. One locus, esterase-2, (EST-2) demonstrated a high level of polymorphism throughout all regions. Malate dehydrogenase-1 (MDH-1) was polymorphic throughout the Mississippi drainage but not elsewhere. Heterozygosity, occurrence of rare alleles, and mean number of alleles per locus were associated positively with estimated population sizes. …
