Boron in forest trees and forest ecosystems

Forest Ecology and Management, 2010
Abstract This review critically examines the role of boron (B) in forests in view of recent findings on B nutrition and the continuing occurrence of B deficiency. Many perceptions about the role of B in plants and its uptake and mobility have been altered since the last review on B in forest trees in 1990. Now there is evidence for a fundamental role

Forest-Related Ecosystem Services

2016
Forests are a crucial element not only of landscapes but also of human living conditions. Covering nearly a third of the earth's land surtace, they stabilize surface soil, prevent erosion and play an essential role in water resource management at the watershed and local levels. They regulate climate and improve air quality. At the same time they are an

Importance of Ectomycorrhiza for Forest Ecosystems

1992
Mycorrhizas are of importance for their tree hosts, as those trees’do not have roots, but mycorrhizas’. The decline of fungi in Europe is relatively well documented. Mycorrhizal fungi have decreased more than saprophytes. Recent studies on acid rain and ectomycorrhizas have raised several new questions.

Ecosystem Management of the Boreal Forest

2016
Abstract Boreal countries are rich in forest resources, and for their area, they produce a disproportionally large share of the lumber, pulp, and paper bound for the global market. These countries have long-standing strong traditions in forestry education and institutions, as well as in timber-oriented forest management.

Mycorrhizae and forest ecosystems

Mycorrhiza, 1992
Mycorrhizae play an important role in regulating patterns of energy and nutrient flux in terrestrial ecosystems. To conceptualize this role I develop the theory behind a simple index of the efficiency of soil resource acquisition by plant root systems (E).

Forest ecosystems and allelopathy

2006
A forest ecosystem is a dynamic set of living organisms: plants, animals and microorganisms, that are characterized by a predominance of trees, all interacting among themselves, with the environment in which they live (soil, climate, water and light) and ecological cycles (energy, water, carbon and nutrients) with which they are closely associated ...

Allelopathy in Forested Ecosystems

2008
In the context of forestry, the concept of allelopathy has recently been expanded from a plant to plant interference phenomenon to an ecosystem-level phenomenon that is influenced by ecosystem disturbance. This chapter reviews the latest development in our understanding of forest allelopathy and the ways in which this new knowledge can be used in ...
