Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms. These biochemicals are known as allelochemicals and can have beneficial or detrimental effects on the target organisms and the community. Allelopathy is often used narrowly to describe chemically-mediated competition between plants; however, it is sometimes defined more broadly as chemically-mediated competition between any type of organisms. The original concept developed by Hans Molisch in 1937 seemed focused only on interactions between plants, between microorganisms and between microorganisms and plants. Allelochemicals are a subset of secondary metabolites, which are not directly required for metabolism of the allelopathic organism.
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms. The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants.
CSIRO Publishing is an Australian-based science and technology publisher. It publishes books, journals and magazines across a range of scientific disciplines, including agriculture, chemistry, plant and animal sciences, natural history and environmental management. It also produces interactive learning modules for primary school students and provides writing workshops for researchers.
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well.

Hybrid models of forest production, sometimes abbreviated to hybrid models, combine growth and yield modelling with physiological modelling.
Olevi Kull was an Estonian professor at the University of Tartu known for his contribution to ecology. Following his death, a memorial fund was established by donations in his memory, which provides travel stipends to students in the fields of plant ecophysiology, forest ecology and ecosystem ecology.
Distinguished Professor David Lindenmayer,, is an Australian scientist and academic. His research focuses on the adoption of nature conservation practices in agricultural production areas, developing ways to improve integration of native forest harvesting and biodiversity conservation, new approaches to enhance biodiversity conservation in plantations, and improved fire management practices in Australia. He specialises in large-scale, long-term research monitoring programs in south-eastern Australia, primarily in forests, reserves, national parks, plantations, and on farm land.
The Farm Forestry Toolbox is a collection of computer programs, referred to as 'Tools', intended to be used by farm forest owners and managers to aid decision making. The Toolbox includes a set of simple 'Hand Tools'; conversion of measurements and map co-ordinates; measuring the volume of stacked logs, slope, basal area; and a survey tool. A second set of more complex tools or 'Power Tools'; can be used to estimate site productivity, volume and value of wood grown for individual trees, at the coupe or stand level and forest estate level.
Crown shyness is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps. The phenomenon is most prevalent among trees of the same species, but also occurs between trees of different species. There exist many hypotheses as to why crown shyness is an adaptive behavior, and research suggests that it might inhibit spread of leaf-eating insect larvae.
Jeannine Cavender-Bares is Professor of Organismic and Evolutionary Biology at Harvard University and Director of the Harvard University Herbaria. She is also adjunct professor in the Department of Ecology, Evolution & Behavior at the University of Minnesota, where she served on the faculty for over two decades. Her research integrates evolutionary biology, ecology, and physiology by studying the functional traits of plants, with a particular focus on oaks.
Reinhart Jan Maria Ceulemans is an emeritus professor of Ecology and previous director of the Research Center of Excellence PLECO of the University of Antwerp.

Nicholas Charles Coops is an Australian-Canadian researcher. He is a Tier 1 Canada Research Chair in Remote Sensing at the University of British Columbia's Department of Forest Resources Management. In 2020, Coops received the Marcus Wallenberg Prize in recognition of his work in with satellite imagery in order to make predictions about forest growth and the ability of forests to store carbon.
Richard Harvey Waring, is an American scientist, educator, and author. Born in Chicago, Illinois, he completed his BSc and MSc at the University of Minnesota, and his Ph.D. at the University of California, Berkeley. His research focuses on the physiological ecology of trees, their health and distribution in response to climatic variation across regions. He has made significant contributions to the understanding of the physiology of stressed trees, the ecology of forests, and the functioning of vegetation across regions. As a co-developer of the forest growth model 3-PG, he won the 2020 Marcus Wallenberg Prize together with Joseph Landsberg and Nicholas Coops.
