Diana Bernadette Beresford-Kroeger (born July 25, 1944) is an Irish botanist, medical biochemist, polymath, and author, who was born in Islington, England and resides near Ottawa, Ontario, Canada.
She is known for her ability to bring an understanding and appreciation of the scientific complexities of nature to the general public. In the foreword to one of her books, Arboretum America, a Philosophy of the Forest, E. O. Wilson wrote, "Diana Beresford-Kroeger is one of the rare individuals who can accomplish this outwardly simple but inwardly complex and difficult translation from the non-human to human realms". [1]
Beresford-Kroeger was orphaned at a young age and raised in Ireland by a bachelor uncle, Patrick O'Donoghue, who was a noted athlete, chemist, scholar, and bibliophile. He nurtured her quest for knowledge and encouraged her to read and discuss everything from Irish poetry, world religions, and philosophy, to physics and quantum mechanics. She attended private schools in Ireland and England. Her summers were spent in the countryside in West Cork and Kerry, which is where she received the lessons of her folk lineage. [2] A great-aunt taught her the early Irish Brehon law as well as Druidic philosophy and ancient ethnobotanical medicine. [3]
Beresford-Kroeger completed her undergraduate studies at University College Cork (UCC), was graduated first in her year (1963) with a Bachelor of Science first class honours in both, botany and medical biochemistry. She completed a Master of Science degree at UCC in 1965. Her thesis was: Frost Resistance and Gibberellins in the Plant Kingdom. [4] She applied scientific testing to plant and human properties held in common. Her Ph.D. thesis completed in 1972, "The Importance of Indole metabolism in plants and its significance in the human condition."
She received a fellowship at the University of Connecticut to study nuclear radiation in biological systems and organic chemistry. [3]
While engaged in cardiovascular research (1973), she completed a diploma in experimental general surgery from the department of surgery at the University of Ottawa. Beresford-Kroeger completed a Ph.D. in biology at Carleton University in 2018. Her thesis was entitled, Myocardial Ischemia and the use of non-typing artificial blood in hemodilution. [5]
Beresford-Kroeger worked as a research scientist at the University of Ottawa and then at the Canadian Department of Agriculture Electron Microscopy Centre, where she discovered cathodoluminescence in biological materials (1972). [6]
From 1973 to 1982, she conducted research at the University of Ottawa physiology department in conjunction with the Ottawa Heart Institute, specializing in hemodynamics. This work led to more efficient organ transplants, cancer delivery of chemotherapy and oxygenation of damaged cardiac musculature. [6] [7] [8] [9] [10]
In the early 1980s, Beresford-Kroeger refused a professorship in medicine to embark on a significant change in her life work. It began with an expansion of her private research garden and arboretum, Carrigliath. Having identified an absence in the scientific community of the ability to present science to the public and the urgent need to address the degradation of nature, she began her career in writing, broadcasting, and lecturing. [2] Flowing from her research and experience at Carrigliath, Beresford-Kroeger published more than 200 articles in magazines, journals, and newspapers in Canada, the United States, and internationally. She also published seven critically acclaimed books on nature. [2]
Her ideas on medical aerosols have recently been confirmed through rigorous scientific analysis of the clinical trials of Dr. Qing Li and the physics of Dr. Mikael Ehn et al. [11] [12]
She has served as a scientific advisor to a number of organizations, including the Irish Woodland League, Ecology Ottawa, Hidden Harvest of Ottawa, Canadian Organic Growers, Archangel Ancient Tree Archive, the Acadian Forest Research Centre, and others.
Beresford-Kroeger has lectured widely throughout Canada, the United States, Europe, and Japan and has appeared on television and radio in North America, Europe, and elsewhere.
The theatrical documentary, Call of the Forest: The Forgotten Wisdom of Trees, [13] released in 2016, was based on Beresford-Kroeger's book, The Global Forest. The documentary film was produced by Jeff Mckay, Edgeland Films, Merit Motion Pictures, and Treespeak Films. Beresford-Kroeger was principal presenter and created the Director's script. This film is accompanied by an extensive educational app on tree planting in North America, also developed by Beresford-Kroeger http://calloftheforest.ca/. She has also been featured in a number of documentaries, including the PBS documentary The Truth About Trees , produced and directed by Ross Spears.
Beresford-Kroeger and her husband live outside of Ottawa, Canada on a large property of 200 acres, preserving rare and native trees. [3]
An arboretum is a botanical collection composed exclusively of trees and shrubs of a variety of species. Originally mostly created as a section in a larger garden or park for specimens of mostly non-local species, many modern arboreta are in botanical gardens as living collections of woody plants and are intended at least in part for scientific study.
Ulmus glabraHudson, the wych elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Ural Mountains, and from the Arctic Circle south to the mountains of the Peloponnese and Sicily, where the species reaches its southern limit in Europe; it is also found in Iran. A large deciduous tree, it is essentially a montane species, growing at elevations up to 1,500 m (4,900 ft), preferring sites with moist soils and high humidity. The tree can form pure forests in Scandinavia and occurs as far north as latitude 67°N at Beiarn Municipality in Norway. It has been successfully introduced as far north as Tromsø and Alta in northern Norway (70°N). It has also been successfully introduced to Narsarsuaq, near the southern tip of Greenland (61°N).
Spiritual ecology is an emerging field in religion, conservation, and academia that proposes that there is a spiritual facet to all issues related to conservation, environmentalism, and earth stewardship. Proponents of spiritual ecology assert a need for contemporary nature conservation work to include spiritual elements and for contemporary religion and spirituality to include awareness of and engagement in ecological issues.
Ulmus rubra, the slippery elm, is a species of elm native to eastern North America. Other common names include red elm, gray elm, soft elm, moose elm, and Indian elm.
Arthur Kroeger, was a Canadian academic and civil servant, who was referred to as the "dean of deputy ministers".
Ulmus laevisPall., variously known as the European white elm, fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and Spain, the latter now considered a relict population rather than an introduction by man, and possibly the origin of the European population. U. laevis is rare in the UK, although its random distribution, together with the absence of any record of its introduction, has led at least one British authority to consider it native. NB: The epithet 'white' elm commonly used by British foresters alluded to the timber of the wych elm.
Ulmus thomasii, the rock elm or cork elm, is a deciduous tree native primarily to the Midwestern United States. The tree ranges from southern Ontario and Quebec, south to Tennessee, west to northeastern Kansas, and north to Minnesota.
Hoyt Arboretum is a public park in Portland, Oregon, which is part of the complex of parks collectively known as Washington Park. The 189-acre (76 ha) arboretum is located atop a ridge in the Tualatin Mountains two miles (3.2 km) west of downtown Portland. Hoyt has 12 miles of hiking trails, two miles of accessible paved trails, and is open free to the public all year. About 350,000 visitors per year visit the arboretum.
Ardeth Mary Margaret Wood was a Canadian graduate student who was killed in a forcible drowning in Ottawa. The initial search for Wood was one of the largest search efforts in the city's history, and the two-year search for her killer was one of the largest manhunts in Canada.
The Dominion Arboretum is an arboretum part of the Central Experimental Farm of Agriculture and Agri-Food Canada in Ottawa, Ontario, Canada. Originally begun in 1889, the Arboretum covers about 26 hectares of rolling land between Prince of Wales Drive, Dow's Lake and the Rideau Canal. Carleton University is located at the opposite side of the Canal. At a latitude of 45°, it can experience extremely hot and humid summers and extremely cold winters.
The University of Guelph Arboretum is an arboretum organized by the University of Guelph in Guelph, Ontario. It was formally established in 1970 by the university and aims to conserve biodiversity and connect people with nature through teaching, research, and community outreach. The space is 165 hectares and is open throughout the year.
Ulmus alata, the winged elm or wahoo, is a small- to medium-sized deciduous tree endemic to the woodlands of the southeastern and south-central United States. The species is tolerant of a wide range of soils, and of ponding, but is the least shade-tolerant of the North American elms. Its growth rate is often very slow, the trunk increasing in diameter by less than 5 mm per year. The tree is occasionally considered a nuisance as it readily invades old fields, forest clearings, and rangelands, proving particularly difficult to eradicate with herbicides.
The hybrid elm cultivar Ulmus × hollandica 'Wredei', also known as Ulmus × hollandica 'Dampieri Aurea' and sometimes marketed as Golden Elm, originated as a sport of the cultivar 'Dampieri' at the Alt-Geltow Arboretum, near Potsdam, Germany, in 1875.
The Field Elm cultivar Ulmus minor 'Viminalis Aurea', probably a "golden" form of Ulmus minor 'Viminalis', was raised before 1866 by Egide Rosseels of Louvain, who was known to have supplied 'Viminalis'.
The Arthur Kroeger College of Public Affairs, colloquially known as Arthur Kroeger College or AKC, is a specialized institute within the Faculty of Public Affairs at Carleton University in Ottawa, Ontario. The College offers undergraduate and graduate programs in the fields of public policy, international studies, and political management. These include the Bachelor of Public Affairs and Policy Management (BPAPM), the Bachelor of Global and International Studies (BGInS), the Master of Political Management (MPM), and the MA in Migration and Diaspora Studies (MDS).
The dwarf wych elm cultivar Ulmus glabra 'Nana', a very slow growing shrub that with time forms a small tree, is of unknown origin. It was listed in the Simon-Louis 1869 catalogue as Ulmus montana nana. Henry (1913), referring his readers to an account of the Kew specimen in the journal Woods and Forests, 1884, suggested that it may have originated from a witch's broom. It is usually classified as a form of Ulmus glabra and is known widely as the 'Dwarf Wych Elm'. However, the ancestry of 'Nana' has been disputed in more recent years, Melville considering the specimen once grown at Kew to have been a cultivar of Ulmus × hollandica.
Ulmus × hollandica 'Klemmer', or Flanders Elm, is probably one of a number of hybrids arising from the crossing of Wych Elm with a variety of Field Elm, making it a variety of Ulmus × hollandica. Originating in the Bruges area, it was described by Gillekens in 1891 as l'orme champêtre des Flandres in a paper which noted its local name, klemmer, and its rapid growth in an 1878–91 trial. Kew, Henry (1913), and Krüssmann (1976) listed it as an Ulmus × hollandica cultivar, though Henry noted its "similarity in some respects" to field elm Ulmus minor, while Green went as far as to regard it as "possibly U. carpinifolia" (:minor).
The Field Elm cultivar Ulmus minor 'Viminalis Pulverulenta' (:'powdery'), also known as 'Viminalis Variegata', a variegated form of U. minor 'Viminalis', was first mentioned by Dieck, in 1885 as U. scabra viminalis pulverulentaHort., but without description. Nursery, arboretum, and herbarium specimens confirm that this cultivar was sometimes regarded as synonymous with U. minor 'Viminalis Marginata', first listed in 1864, which is variegated mostly on the leaf margin. It is likely, however, that 'Pulverulenta' was the U. 'Viminalis Variegata', Variegated Twiggy-branched elm, that was listed and described by John Frederick Wood, F.H.S., in The Midland Florist and Suburban Horticulturist 1847 and 1851, pre-dating both Kirchner and Dieck. Wood did not specify the nature of the variegation.
The Siberian elm cultivar Ulmus pumila 'Pinnato-ramosa' was raised by Georg Dieck, as Ulmus pinnato-ramosa, at the National Arboretum, Zöschen, Germany, from seed collected for him circa 1890 in the Ili valley, Turkestan by the lawyer and amateur naturalist Vladislav E. Niedzwiecki while in exile there. Litvinov (1908) treated it as a variety of Siberian elm, U. pumilavar.arborea but this taxon was ultimately rejected by Green, who sank the tree as a cultivar: "in modern terms, it does not warrant recognition at this rank but is a variant of U. pumila maintained and known only in cultivation, and therefore best treated as a cultivar". Herbarium specimens confirm that trees in cultivation in the 20th century as U. pumilaL. var. arboreaLitv. were no different from 'Pinnato-ramosa'.
