Marr\u2019s approach was experiential; we never cracked a book for it seemed a month that early fall of 1958, but spent time out near Marshall Mesa observing and trying to interpret what we saw. [Dr. Marr] never had ongoing projects in which graduate students seeking thesis topics were merely inserted. Students searched out topics that they were most interested in and pursued them with help from Marr. He did this because he was deeply convinced that choosing a research area and subject should be a highly personal decision that would encourage the students to return to the study area and research topic throughout their lifetime. \u2014Resolution of Respect, Cooper et al., 1990.<\/p><\/blockquote>\n Ecology of the Forest-Tundra Ecotone on the East Coast of Hudson Bay<\/em><\/a> Ecological Monographs, Vol. 18, No. 1 (Jan., 1948), pp. 117-144 John W.

His class observed the krummholz, the stunted, windblown, shrub-like trees above timberline. Drifts covered these small islands of trees located at the lower edge of the alpine tundra; only a few branches reached above the snow cover. Marr was explaining that severe winds laden with ice crystals pruned the windward sides of the tree islands, shaping them asymmetrically. As he spoke, a ptarmigan walked from one krummholz to another, methodically plucking buds. Astounded, Marr admitted he had never seen a ptarmigan eating spruce buds before, \u201cwind-trimming\u201d his krummholz. He conceded that factors other than wind might also contribute to ecosystem dynamics.\u201d References<\/strong> John W.

\nThrough his teaching and research at the University of Colorado, Boulder, John Marr introduced many students to the ecology of the Front Range of Colorado. In 1951, he founded the Mountain Research Station (today known as INSTAAR), which has introduced hundreds more students\u2014as well as researchers from around the planet\u2014to Niwot Ridge, now a designated LTER, as well as to montane and alpine ecology. Many others were introduced to Rocky Mountain ecology through his monograph, Ecosystems of the East Slope of the Front Range of Colorado<\/em>, published in 1961. Dr. Marr served as director of INSTAAR from 1951 to 1967.

\nIn 1994, the John W. Marr Memorial Ecology Fund was established to assist PhD students with small grants for field research in plant ecology in the Rocky Mountains or the Arctic. The fund is administered through the University by a committee composed, in part, of former students. Each year, promising students at selected universities in the Rocky Mountain West are partially supported by this fund; to date more than 50 students have benefited from these small grants.
\nIn honor of Dr. Marr, the Colorado Native Plant Society<\/a> established the Marr Fund, which provides small grants to support research on the biology of Colorado native plants and plant communities.<\/p>\nJohn Marr\u2019s Legacy<\/h3>\n
