  • Benthic Macroinvertebrate communities of Southwestern Lake Ontario Following Invasion of Dreissens

    Haynes, James M.; Stewart, Timothy W. (International Association of Great Lakes Research, 1994)
    Changes in benthic macroinvertebrate communities inhabiting natural cobble and artificial reef substrates in southwestern Lake Ontario were quantified before and after the invasion of dreissenid mussels in the late 1980s. Dreissenids comprised 79% and 93% of the cobble and reef communities in 1991-1992 (post-invasion) and replaced the amphipod, Gammarus fasciatus, which was the most abundant species at both habitats in 1983 (pre-invasion). Total abundance of non-Dreissena species was significantly greater in 1991-1992 than in 1983. Comparisons of macroinvertebrate community similarity in 1983 and 1991-1992 indicated that previously established taxa did not change substantially between sampling periods, but their proportions in the community did. Although many factors may have contributed to the changes we observed, our results support theories that Dreissena is facilitating energy transfer to the benthos by pseudofecal/ fecal deposition and that mussel colonies are providing additional habitat for other invertebrate taxa.
  • . Benthic macroinvertebrate communities in southwestern Lake Ontario following invasion of Dreissena and Echinogammarus: 1983-2000.

    Haynes, James M.; Tisch, Nancy A.; Mayer, Christine M.; Rhyne, Randall S. (Journal of the North American Benthologic Society, 2005)
    Benthic macroinvertebrate communities were quantified at natural cobble and artificial reef sites in Lake Ontario in 1983 (7 y pre-Dreissena invasion) and in 1991-1992 and 1999-2000 (1-2 and 9-10 y post-Dreissena invasion, respectively). Overall, the natural cobble community had higher species diversity and community abundance than the artificial reef community. While taxonomic composition of both communities remained consistent during the study period, organism abundance (excluding Dreissena) increased sharply from 1983 to 1991-1992, and that all taxa declined to 1983 levels by 1999-2000. From 1991-1992 to 1999-2000, Dreissena bugensis, which mostly replaced D. polymorpha, and Echinogammarus ischnus (all invasive species) appeared in the studied community. We conclude that the transition from D. polymorpha to D. bugensis and processes associated with the ongoing oligotrophication of Lake Ontario are responsible for the reduced density of large-bodied Dreissena in the nearshore region of the lake, and that changes in the Dreissena population are largely responsible for changes in the non-Dreissena benthic macroinvertebrate community.
  • Survey of Buttonwood Creek, Monroe County, NY to Determine Habitat Availability for and Relative Abundance of a Species of Special Concern, the Pirate Perch (Aphredoderus sayanus)

    Haynes, James M. (SUNY Brockport Department of Biological Sciences, 1994-06-02)
    We determined how much suitable habitat for Pirate Perch remains in Buttonwood Creek, sampled those habitats to determine where the species still exists in the creek, and predicted the likely impact of a bridge replacement and associated channel alterations on the Pirate Perch population
  • Preliminary Survey of Fish Communities in Three Tributaries of the Braddock Bay Watershed.

    Haynes, James M. (SUNY Brockport, Department of Biological Sciences, 1987-11)
    SUNY Brockport collaborated with Monroe County, New York to assess fish communities in three tributaries of Braddock Bay with different development histories: Northrup Creek, Larkin Creek and Buttonwood Creek.
  • Building Global Relationships: OER and Collaborative Online International Learning Courses

    Orzech, Mary Jo; Zhang, Jie; Kegler, Jennifer; Pearlman (University of Rochester), Ann; Greenfield (Syracuse University), Victoria (Sage Journals, 2023)
    Using Open Educational Resources (OER) in Collaborative Online International Learning (COIL) courses provides students and faculty the opportunity to share content, enhance knowledge, and develop intercultural competence across geopolitical and other boundaries. Faculty perceptions at the research site regarding benefits and challenges of using OER are consistent with positive findings of other OER research that validate its potential. This case study describes experiences of two college courses taught with different international partners. It shares the journey of co-planning, implementing, and revising assignments highlighting OER instructional materials. Technology and accessibility considerations influence the curricular decisions for each course. They demonstrate how the timely availability of relevant OER content can be particularly impactful for international learning environments like COIL. The article underscores the faculty-librarian-instructional designer collaboration throughout the project and offers suggestions for future study.
  • Institutional Repository Migration: Opportunity for Change

    Laird, Dana; Orzech, Mary Jo; O'Sullivan, Pam; Wierxbowski, Ken (Association of College and Research Libraries, 2023)
    Migrating an institutional repository requires a special blend of skill, cooperation, and good fortune. This chapter outlines the mindset and management involved in moving an existing institutional repository from Digital Commons to another platform (DSpace) in a U.S. public comprehensive college library. This article highlights both challenges and opportunities and provides perspective for others considering similar undertakings. The migration required clear goals, tools, and administrative expertise. It prompted timely discussion about enhanced user experience, process improvements, inclusive patron practices, and sustainability.
  • Fall movements of brown trout in Lake Ontario and a tributary.

    Haynes, James M.; Nettles, David C. (New York Fish and Game Journal, 1983-01)
    Movements of radio-tagged brown trout during pre-spawning, spawning and post-spawning periods were studied in Lake Ontario and Sandy Creek (Monroe County, NY) from September through November 1980. Until mid-October, most of the brown trout remained offshore in deep water during the day and moved inshore to shallow water at night, after which fish began to move upstream to spawn. In November, after spawning, tagged fish moved offshore to deeper water.
  • Comparison of benthic communities in dredged and undredged areas of the St. Lawrence River, Cape Vincent, N. Y.

    Haynes, James M.; Makarewicz, Joseph C. (Ohio Academy of Science, 1982)
    Macroinvertebrate communities were compared in dredged and undredged areas of the St. Lawrence River near Cape Vincent, N. Y., by sampling with a Ponar dredge in spring, summer and fall seasons. Total macroinvertebrate abundance was greater in undredged areas. Differences in total invertebrate abundance and relative abundance of individual species in dredged and undredged areas appear to be related to the presence of gyttja-type sediments caused by breakwater construction and dredging operations at least 40 years ago.
  • Movements of Pacific Salmon in Lake Ontario: Evidence for wide dispersal

    Haynes, James M.; Keleher, Christopher J. (Journal of Freshwater Ecology, 1986-06)
    After radio tagging, Pacific Salmon (Coho and Chinook) dispersed widely along shore (spring) and throughout Lake Ontario (summer) in 1984. They did not occupy areas near shore after water temperatures exceeded 9-10 oC, except when winds produced upwelling of colder water at the lake’s surface close to shore in summer. No significant differences were observed between the two species re: distances moved, daily movement rates, and water temperature occupied. One fish moved at least 500 km during 4 months of tracking.
  • . Disseminating Successful Undergraduate Science Curriculum Adaptation and Implementation Strategies and CCLI-ND Grant-Writing Techniques: Regional Workshops Led by Successful Innovators and Experienced Investigators, Evaluating Faculty Change Processes and Assessing Student Understanding of STEM Concepts

    Haynes, James M.; Hluchy, Michele M.; Connolly, Mark R. (American Association for the Advancement of Science (AAAS), 2004)
    From 1980-2006, we showed multiple cohorts of undergraduate faculty how environmental impact analysis can be used in their STEM courses to tie together scientific concepts and theories, research and analytical techniques, and mathematical and communication skills appropriate to address local environmental problems. During more than 20 summer workshops (5 days to 3 weeks), we chose themes of Stressed Stream Analysis or Great Lakes Ecosystem Dynamics because those topics allowed us to demonstrate (and for participants to learn hands-on) new, ecologically based approaches to pollution control and to use spreadsheet models to explore the movements of pollutants in ecological systems. Faculty participants (mostly from the disciplines of biology, chemistry, geology, and engineering) worked in teams to address the environmental problems presented to them by the workshop instructors then wrote environmental impact statements. In later stages of our workshop activities for undergraduate faculty, we also developed units on developing their capacity to use and modify new assessment instruments to gather better data on student learning and managing the challenges of undertaking significant pedagogical and curricular changes in their courses.
  • Movements and temperatures of radio tagged salmonines in Lake Ontario and comparisons with other large aquatic ecosystems.

    Haynes, James M.; Gerber, Glenn P. (Journal of Freshwater Ecology, 1989-12)
    We used six years of radiotelemetry data (1980-86) to compare movements and temperatures occupied by four introduced salmonine species (174 tagged fish) in the nearshore region of Lake Ontario. Movement patterns, net movement rates, water temperatures occupied, and harvest rates by anglers were generally similar among species and seasons. The movement patterns and thermal habitats of salmonines in Lake Ontario generally were in the mid-range of those report for conspecifics in other large lakes and the North Pacific Ocean.
  • Diel and seasonal movements of White Sturgeon (Acipenser transmontanus) in the mid-Columbia River.

    Haynes, James M.; Gray, R.H. (Fishery Bulletin, 1981)
    In the mid-Columbia River, radio-tagged White Sturgeon (Acipenser transmontanus) exhibited seasonal and diel movement patterns from 1975-1977. Seasonally, movements >2 km away from release locations began in spring when water temperature exceeded 13 oC and ended in autumn when water temperature fell below 13 oC. Daily, sturgeon exhibited movements among habitats with different substrates, as measured by changes in water temperature during 24-h diel periods. Movement to cooler, deeper areas of the river occurred before sunrise, while movement to warmer, shallower areas peaked after sunset. Because water temperatures varied by only a few tenths of a degree among substrate areas, it is likely that photoperiod influenced sturgeon movements between deeper, darker resting areas and shallower, food-rich feeding areas.
  • Benthic Macroinvertebrate Communities in Southwestern Lake Ontario Following Invasion of Dreissena: Continuing Change

    Haynes, James M.; Stewart, Timothy W.; Cook, George E. (International Association of Great Lakes Research, 1999)
    Benthic macroinvertebrate communities were compared and quantified at natural cobble and artificial reef sites in Lake Ontario in 1983 (pre0-Dreissena invasion), and in both 1991-1992 and 1995 (1 to 2 and 5 years post-Dreissena invasion, respectively). Diversity and abundance of non-dreissenid macroinvertebrates generally rose from 1983 to 1991-1992, but returned to 1983 levels or lower by 1995. Although community similarity (excluding Dreissena from analysis) remained high across study years, the 1995 invertebrate community more closely resembled the pre-Dreissena community of pre-1983 than the initial post-Dreissena community of 1991-1992 because of recent declines in the absolute abundance and diversity of macroinvertebrates. In particular, gastropods responded negatively to Dreissena or to associated benthic habitat or community changes that occurred from 1991-1992 to 1995. These results suggest that short- and long-term effects of Dreissena on other organisms may be quite different, and illustrate the need for long-term monitoring of biological communities in order to more fully determine effects of invasive species or other environmental perturbations on ecosystems.
  • Response of Sport Fishes to Thermal Discharges into the Great Lakes: Is Somerset Station, Lake Ontario, Different?

    Haynes, James M.; Gerber, Glenn P.; Buttner, Joseph K. (International Association of Great Lakes Research, 1989)
    To assess potential thermal impacts of Somerset Generating Station on sport fishes, the frequencies and durations of encountering the thermal discharge at Somerset Station were determined by tagging 121 salmonines and 58 centrarchids with temperature-sensing radiotransmitters. Encounters of the Lake Ontario shoreline occupied by Somerset Station averaged 0.7 and 0.1 per fish for salmonines and centrarchids, respectively. Salmonines averaged 5.5 h at the station per encounter. Four centrarchids established residence areas in the lake near the station for 29-79 d; others averaged 3.5 d at the station. Salmonines and centrarchids occupied waters off Somerset Station on 6.7% and 16.0% respectively, of the days they were tracked. No temperatures occupied by fish at the station exceeded critical thermal maxima for salmonines (20 - 25 degrees C) or centrarchids (30 - 37 degrees C). Salmonines occupied heated water >2 degrees C above ambient lake temperatures on 1.3% of the 1,983 occasions when temperatures were recorded, while centrarchids averaged 0.1% of 1,773 observations. Rare encounters of and lack of attraction to the thermal discharge were attributed to characteristics of the discharge (600+ m offshore, small delta T, small volume/area), to unremarkable lake habitat (flat bottom, physically similar to other regions of southcentral Lake Ontario), and to the generally wide-ranging movements of fishes in Lake Ontario. Comparing results from Somerset Station with similar studies at other Great Lakes power stations suggests that discharge design and lake habitat importantly influence the extent of fish attraction to thermal discharges.
  • Movements of Rainbow Steelhead Trout (Salmo Gairdneri) in Lake Ontario and a Hypothesis for the Influence of Spring Thermal Structure

    Haynes, James M.; Voiland, Michael P.; Olson, Robert A.; Winter, Jimmy D. (International Association of Great Lakes Research, 1986)
    To examine movements of rainbow/steelhead trout (Salmo gairdneri) and associated environmental influences, 28 fish were radiotagged in and near a tributary of Lake Ontario during spring spawning runs in 1981 and 1982. Trout initially entering the lake from the tributary generally exhibited east-west reversals of movement along the southern shore of Lake Ontario before dispersing offshore. Seasonal movement rates averages 3.2 +/- 1.6 km/d over periods of 6 - 94 d; mean short term rates were 0.50 +/- 0.46 km/h. Temperatures occupied in the lake were 9.1 +/- 3.8 degrees C. Movements offshore and ultimate disappearances occurred from April to July, but were most pronounced when temperatures near shore exceeded 10 degrees C. By linking trout movements to seasonal thermal structure in Lake Ontario, a testable hypothesis was established to explain the distribution of rainbow trout in spring and early summer. Based on tracking data, information provided by south shore anglers, and literature on the physical limnology of Lake Ontario, we hypothesize that rainbow trout disperse off shore in spring with thermal fronts, particularly in the 6 - 8 degree C zone known as the spring thermocline.
  • Finding Salmon and Trout in Lake Ontario, 1985

    Haynes, James M. (Charter Industry Trade News, 1985-03)
    Using radiotelemetry and vertical gill nets, we studied the movements and habitat preferences of brown trout (Salmo trutta), steelhead (Oncorhynchus mykiss), Chinook Salmon (O. tshawytscha), Coho Salmon (O. kisutch) and Lake Trout (Salvelinus namaycush) in Lake Ontario. No species were available for radio tagging in the summer, Brown Trout and Chinook and Coho Salmon were available in the fall, and Brown Trout and Steelhead were available in the spring. Steelhead responded strongly to offshore thermal breaks at the surface in the spring. Vertical gill nets in the summer captured Brown Trout just above the thermocline and Lake Trout below it, while Chinook Salmon ranged widely a above and below the thermocline. Our studies helped Lake Ontario anglers to increase their catches of stocked salmonids in the lake.
  • Environmental impact assessment: Melding classroom instruction with problem-solving experience

    Haynes, James M.; Thorburn, Gary W.; Gannon, John E. (National Science Teachers Association, 1982)
    Undergraduates were presented with realistic environmental situation (building a marina in a stream mouth/ wetland on the Lake Ontario shoreline). After learning about state and federal laws and procedures for environmental impact analysis, they sampled and identified terrestrial and aquatic organisms that might be affected by marina construction, operation and dredging (and researched literature about those topics) then in teams of 3-5 students wrote separate Environmental Impact Statements for the proposed project. Students gained real world experience that would help them with future employment opportunities.
  • Zebra Mussels and Benthic Macroinvertebrate Communities of Southwestern Lake Ontario and Selected Tributaries: Unexpected Results?

    Haynes, James M. (Great Lakes Research Review, 1997-04)
    Since the zebra mussel (Dreissna polymorpha) colonized the Great Lakes Ecosystem, ecologists and managers have expressed concern about potential impacts it would have on native benthic macroinvertebrate communities in lakes and streams. We compared post-Dreissena invasion data (1991-1992) with pre-invasion data (1983) from the same sites in Lake Ontario. Dreissena was the overwhelmingly dominant taxon in 1991-1992. Nevertheless, the overall abundance of other benthic macroinvertebrates, and the number of taxa collected, were greater following establishment of Dreissena. Our study failed to provide evidence that Dreissena had induced a population in any non-bivalve taxon that was present in 1983. The invasion of Dreissena and other recent environmental changes appear to have created conditions that are more favorable for most benthic macroinvertebrate taxa in the nearshore region of Lake Ontario. We also asked why zebra mussels have not colonized many creeks in Western New York, some with apparently ideal habitat, that are fed partially by water from the Erie Canal which is a source of Dreissena larvae. Counts of Dreissena larvae and counts of chlorophyll a were much higher in the canal than in out study creek, yet water quality, current velocity and particulate organic carbon concentrations in the creak and the canal were very similar. Four factors appear to limit colonization of creeks by the zebra mussel: 1) Retention of larvae by wetlands through which discharges from the canal often flow, 2) Filtering of phytoplankton and larvae by dense beds of adult zebra mussels often found at the beginning of channels connecting the canal to creeks, 3) Inappropriate food quality (e.g., lack of small0diameter phytoplankton with important fatty-acid constituents) reaching creeks from the canal, or 4) Muddy substrates inappropriate for attachment and filter-feeding by Dreissena.
  • Stressed Stream Analysis--Addressing Environmental Problems in Local Communities

    Haynes, James M. (Journal of College Science teaching, 1998-09)
    Science education is routinely accomplished within relatively narrow disciplines, but by its nature, environmental science must involve many disciplines to be effective.
  • Influence of Little Goose Dam on Upstream Movements of Adult Chinook Salmon, Oncorhynchus tshawytscha

    Haynes, James M.; Gray, Robert H. (Fishery Bulletin, 1980)
    A major environmental and economic concern in the Pacific Northwest is the continuing decline in the numbers of Columbia and Snake River salmonids. The author used radiotelemetry to evaluate effect of Little Goose Dam on the movements of chinook salmon in the lower Snake River, and compared the results with those of previous studies at other dams.
