<em>Abstract</em>.—The identification, protection, and restoration of spawning habitat for Muskellunge <em>Esox masquinongy </em>in Green Bay, Lake Michigan are vital steps for re-establishing a self-sustaining population. This study was designed to locate spawning areas, document and model spawning habitat preferences, assess natural recruitment, and determine if suitable habitat was found throughout Green Bay (Fox River, lower Green Bay, Menominee River, and Little Sturgeon Bay). Radio transmitters were inserted into the oviduct of mature female Muskellunge prior to spawning and expelled transmitters were later located using radio telemetry to identify spawning locations. Between 2009 and 2010, 26 of 37 (70%) implanted transmitters were located as deposited at spawning locations. Using identified spawning locations, habitat selection was estimated for key environmental variables, and MaxEnt (maximum entropy) was utilized to model Muskellunge spawning habitat in the Menominee River, as it was the only study area where natural reproduction was documented. Menominee River Muskellunge showed significant preferences for spawning in areas with shallow bottom slopes (5%), with medium-to-high submerged aquatic vegetation coverage (>33%), where coarse woody debris was present, and where dominant substrates were sand or cobble. MaxEnt modeling predicted a ~2.5 magnitude greater likelihood of spawning at an average spawning location compared to an average background location. Comparisons of available habitat among study areas showed the Menominee River contained more spawning habitat with preferred characteristics. Results from this study are important steps in identifying spawning habitat as a potential limiting factor to successful Muskellunge reintroduction and models could be used to locate suitable areas to stock and guide delineation of critical spawning habitat to designate for protection.

On Wednesday morning September 21, 1795, only a year after he was appointed president of Yale College, forty-four-year-old Timothy Dwight began the first of his thirteen excursions through New England and upstate New York. On six of his thirteen trips, he traveled through the Connecticut Valley, a valley he was familiar with since childhood and was linked to by both family and sentiment. The Connecticut River Valley was changing, as Dwight made his several trips through it. It was transformed under the impact of human activity. Increasingly, mill dams and factory villages were being built along the river and its tributaries. Technology, science, and the market were restructuring the way people were interacting with their environment. The land became less wild. That “civilizing” of nature, as Dwight called it, began first on the alluvial soils of the lower and central valley in the eighteenth century and then spread north and up into the hill country in the early years of the nineteenth century. By the end of the fifth decade of the nineteenth century, this new world had pretty much taken shape, and valley residents began to take stock of the changes that had occurred. Dwight began this process of accounting at the beginning stages of that transformation. And it was in the Connecticut River Valley that the changes made the biggest impact on him. At the center of the Connecticut Valley runs New England’s largest waterway. The Connecticut River flows south some four hundred miles from a series of small lakes in the swampy district of northern New Hampshire on the Canadian border. It eventually spills into Long Island Sound at Saybrook, Connecticut. To the west and east of the river are mountain ranges, the Housatonic and Green Mountains to the west and the White Mountains to the east. In northern New Hampshire and Vermont, the river travels through a narrow and rough mountain valley. As the river moves south into central Vermont and New Hampshire, the valley widens, particularly on the river’s western shore, and is intersected with tributary rivers and valleys.

<em>Abstract.</em>—Gametes of green sturgeon <em>Acipenser medirostris</em> (caught in the Klamath River, California) and farm-reared white sturgeon <em>A. transmontanus</em> were obtained using hormonal induction of ovulation and spermiation. The offspring of one female in each species were reared in the laboratory, to compare their development and growth. Green and white sturgeon embryos had similar rates of development and hatched after 169 h and 176 h, respectively, at incubation temperature 15.7 ± 0.2°C. Embryos of both species exhibited similar holoblastic development and passed through 36 stages characteristic of acipenserids. Green sturgeon fertilization and hatching rates were 41.2% and 28.0%, compared with 95.4% and 82.1% for the white sturgeon. Larval survival to 45 d (metamorphosis) was 93.3% in green and 92.1% in white sturgeon. Newly hatched green sturgeon (length 13.7 ± 0.4 mm, mean ± SD) were larger and less pigmented, compared with white sturgeon. They had large ovoid yolk sacs and did not exhibit pelagic behavior that was observed in white sturgeon. The onset of exogenous feeding in green sturgeon occurred at age 10–15 d and length 24.0 ± 0.5 mm, and metamorphosis was completed at age 45 d and length 74.4 ± 5.9 mm (rearing temperature 18.5 ± 0.2°C). Weight and length of green sturgeon larvae and juveniles were considerably greater than in white sturgeon at each sampling time, but the relative growth rate and weight-length relationship were similar in both species. This suggests an effect of larger egg size and maternal yolk supply on the growth of green sturgeon. We conclude that green sturgeon differs from the white sturgeon in their reproductive strategy and, potentially, reproductive habitat.

University campus has a profound impact on the growth and development of college students. In this study, we use Photovoice method to explore how female freshmen perceive and build up the sentimental ties with the campus. Participants (n=54; aged 18-19 years) were asked to photograph and discuss perceived positive/negative places on Tongji University campus (Shanghai). In the process of analysis, thematic and content analysis was conducted by natural language processing software, the correlation of key words were examined by Rost Content Mining. The study shows that place attachment comes from
