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.

Contents

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]

Early life

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]

Education

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]

Early work

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]

Later work

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.

An arboretum is a botanical collection composed exclusively of trees 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.

<i>Ulmus glabra</i> Species of flowering plant in the elm family Ulmaceae

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 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.

<i>Ulmus laevis</i> Species of tree

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.

<i>Ulmus alata</i> Species of tree

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.

<i>Ulmus</i> × <i>hollandica</i> Wredei Hybrid elm cultivar

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.

<i>Ulmus minor</i> Viminalis Aurea Elm cultivar

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'.

<i>Ulmus glabra</i> Nana Elm cultivar

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.

<i>Ulmus</i> × <i>hollandica</i> Klemmer Elm cultivar

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).

<i>Ulmus minor</i> Viminalis Pulverulenta Elm cultivar

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.

<i>Ulmus pumila</i> Pinnato-ramosa Elm cultivar

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'.
