His multidisciplinary approach, quantitative skills, imagination and intuition advanced our knowledge and understanding of the ocean enormously. Of his many significant scientific contributions to oceanography, he is best known for his pioneering work in developing simple numerical models for improving the understanding of the dynamics of marine ecosystems with a focus on plankton. He helped transform oceanography from a descriptive to a quantitative science. His early career was spent in the United States at the Bingham Oceanographic Laboratory of Yale University and the Woods Hole Oceanographic Institution. In 1965, at the peak of his career, he immigrated to Canada to become the director of the Institute of Oceanography at Dalhousie University. Under his leadership, the Institute evolved into the Department of Oceanography, which became an internationally recognized centre for marine research and teaching. During this period, he also played a prominent role in the development of the broader Canadian oceanographic community. He served as a wonderful example of how scientific research, teaching and a life should be carried out.","PeriodicalId":153215,"journal":{"name":"Proceedings of the Nova Scotian Institute of Science (NSIS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131354859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dr. Alexander H. MacKay was the superintendent of public schools in Nova Scotia from 1891-1926. Beginning in 1896 MacKay instructed all the school teachers of Nova Scotia to have their students collect data on the first appearances of numerous plants, animals, and seasonal events, and then summarized the data himself. The summaries of the phenological data collected in this massive citizen science project were then published in the Proceedings of the Nova Scotian Institute of Science in a consistent fashion over the period 1901-1923. We analyze five species from the summary MacKay data for Nova Scotia, producing a model for First Appearance Time of flowering for each, as a function of latitude, longitude, mean monthly temperatures for many months, and sea ice off the coast of Newfoundland in winter months. Our model produces good agreement between predicted FATs and those FATs we find in the literature.Key Words: 1901-1923, Alexander MacKay, First Appearance Time (FAT), flowering, latitude, longitude, mean monthly temperatures, Nova Scotia, sea ice.","PeriodicalId":153215,"journal":{"name":"Proceedings of the Nova Scotian Institute of Science (NSIS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124585853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most sites were intertidal rocky shores, there were one small salt marsh and one eelgrass bed included in the study, and some subtidal sampling was conducted utilizing SCUBA and snorkeling. The Brier Island seaweeds comprised 152 species and varieties of which 62 were Rhodophyta, 44 were Chlorophyta, 44 were Phaeophyceae, and two species were Xanthophyceae. Three species were new records for eastern Canada: Colaconema bonne- maisoniae, C. endophyticum, and Elachista stellaris, all were pre- viously recorded from New England. The flora included eight non- native species of which Colpomenia peregrina and Bonnemaisonia hami- fera (both gametophytic and tetrasporophytic stages) were abundant at two or more sites, and the invasive Codium fragile subsp. fragile was recorded based on a single drift specimen. With 150 species and varieties of seaweeds, Brier Island has the highest species richness of a limited area of eastern Canada. The Cheney floristic index at 2.4 is higher than comparable areas, and suggests that many additional brown algae remain to be found.Keywords: Chlorophyta, Colaconema, Bay of Fundy, Brier Island, Phaeophyceae, Rhodophyta, seaweeds","PeriodicalId":153215,"journal":{"name":"Proceedings of the Nova Scotian Institute of Science (NSIS)","volume":"212 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122456954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They document plant communities as well as plant and animal species of conservation concern. The Protected Areas Branch wished to have an assessment of the value of these surveys. Fourteen years of sampling data in 80 Wilderness Areas and Nature Reserves were used to determine detectability, density and distribution of species of conservation concern. Two hundred and twenty-two occurrences of species of interest were re- corded. Nine bird species and 19 plant and lichen species were recorded 2 or more times. Densities for bird species ranged from 0.023 individuals per km of transect (± 0.012) for the Boreal Chickadee to 0.727-km (± 0.007) for the Eastern Wood Pewee. Plants densities ranged from 0.02 individuals per km (± 0.01) for the Round-Leaved Orchid to 27.1 individuals per km (± 10.4) for the Bulblet Bladder Fern. Most of the species of conservation concern were rare with 66% being found only once. The method used for the current biodiversity transect surveys appears to be adequate for the more common species of conservation concern when a single protected area is examined. However, less than half the species analyzed had a 95% confidence of being detected within the mean sample length of the transect (4.5 km). All species analyzed were within the sample length when all protected areas were combined suggesting that the present methodology is more useful as a system wide survey rather than for individual protected areas. Twenty-eight of eighty-three species of conservation concern detected during the survey occurred frequently enough for density calculations. Methods that might increase the value of the surveys include grouping species, using species richness measures, using occupancy or accepting lower confidence intervals and confidence limits.Keywords: biodiversity survey, species of conservation concern, species at risk, protected areas","PeriodicalId":153215,"journal":{"name":"Proceedings of the Nova Scotian Institute of Science (NSIS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116867133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
