Phytoplankton species diversity of 27 lakes and ponds of Costa Rica (Central America)

The literature on species diversity of phytoplankton of tropical lakes is scarce, and for the main part comes from studies of the big lakes in Africa, or deep lakes in South America, leaving a gap in the information about small shallow tropical lakes. In the present work the phytoplankton species composition and diversity of 27 shallow lakes and ponds in Costa Rica (Central America) was studied. The species composition was found to agree with other studies of tropical lakes, with a dominance of Chlorophyta, Cyanophyta, or in some cases Bacillariophyta or Euglenophyta; and a general paucity of Chrysophyta and Cryptophyta. Species richness varied considerably among the lakes, and tended to decrease with an increase in lake elevation. A low evenness in the species abundances was found, with one or more species outnumbering the rest by several orders of magnitude. Individual species abundances and species composition was found to vary with time in Rio Cuarto Lake, a meromictic lake situated in a region with low seasonal change in precipitation. In comparison with the phytoplankton of temperate lakes, the phytoplankton of the tropical lakes studied tended to have a lower evenness of species abundances, although species richness may be similar to temperate figures in some cases. Diversity indices sensitive to changes in the abundance of rare species tend to be higher in the tropical lakes studied; diversity indices sensitive to changes in the numbers of abundant species tend to be similar between the temperate and tropical lakes examined.

Enhancing personal effectiveness : the impacts of Costa Rica Outward Bound on students in an independent school in southwestern Ontario

This project examines students in a private school in southwestern Ontario on a 17 -day Costa Rica Outward Bound Rainforest multielement course. The study attempted to discover whether voluntary teenage participants could increase their self-perceptions of life effectiveness by participating in a 17-day expedition. A total of9 students participated in the study. The experimental design that was implemented was a mixed methods design. Participants filled in a Life Effectiveness Questionnaire (LEQ) at four predesignated times during the study. These time intervals occurred (a) before the trip commenced, (b) the first day of the trip, ( c) the last day of the trip, and (d) 1 month after the trip ended. Fieldnotes and recordings from informal group debriefing sessions were also used to gather information. Data collected in this study were analyzed in a variety of ways by the researcher. Analyses that were run on the data included the Friedman test for covariance, means, medians, and the Wilcoxon Pairs Test. The questionnaires were analyzed quantitatively, and the fieldnotes were analyzed qualitatively. Nonparametric statistical analysis was implemented as a result of the small group size of participants. Both sets of data were grouped and discussed according to similarities and differences. The data indicate that voluntary teenage participants experience significant changes over time in the areas of time management, social competency, emotional control, active initiative, and self-confidence. The types of outcomes from this study illustrate that Outward Bound-type opportunities should be offered to teenagers in Ontario schools as a means to bring about self-development.

Gainsborough [Presbyterian] Church records, 1833-1836, 1841-1846, 1855-1857, 1860-1864, 1866 [photocopy]

The Gainsborough Presbyterian Church was organized prior to 1833, but no records were kept until this date. In 1809, the church was lead by Rev. Daniel Ward Eastman. In 1833 the church became part of the Niagara Presbytery of the American Presbyterian Church. The records include transfer of membership, records of marriages, lists of subscribers and session minutes. Photocopies from originals were made in 1977 by E. Phelps, University of Western Ontario, prior to their deposit with the United Church of Canada Archives, Toronto, Ont.

He also conducted business in the Village of Niagara Falls. He purchased large tracts of land (largely on credit) with the intent to sell the land at a profit. However, the sales did not meet his expectations and Rathburn found himself over-extended on credit, ultimately leading to his financial ruin.Jesse P.

Intemperance at Meredith Bridge, 1836

A document titled "Plain Facts, In relation to the state of intemperance at Meredith Bridge, ascertained by a committee recently appointed for that purpose". The introduction to the document reads: "The whole population of the village, embracing a tract of territory less than one mile from the Bridge, is nine hundred forty. The number of families within those limits is one hundred and sixty-six. Of the heads of these families, thirty-eight are intemperate, - seventy are temperate drinkers; the remainder abstain wholly from the use of distilled and vinous liquors. There are ninety-six children in those families,in which there is one intemperate parent. The number of children who have temperate parents is one hundred and fifty-nine. The other families have one hundred and forty-four children. Beside the above, there are thirty-seven young men. Of this number, twelve are decidedly intemperate; seventeen are temperate drinkers, and eight subscribe to the doctrine of total abstinate. In the whole Village, there are, at the least, fifty-two decidedly intemperate. There are sold in this Village, annually nine thousand gallons of spirituous liquors, at a cost not less than $6,750. Add to this the other cost attendant on the use of spirituous liquors, estimated to equal that of the liquor itself, and we have an item of expense of $13,500, occasioned by the use of intoxicating drink. The above facts are offered for the serious consideration of the citizens at Meredith Bridge. March 1836".
