Defining Old Growth for Fire-adapted Forests of the Western United States
Ecology and Society, 2007 There are varying definitions of old-growth forests because of differences in environment and differing fire influence across the Intermountain West. Two general types of forests reflect the role of fire: 1) forests shaped by natural changes in structure

TFP Growth in Old and New Europe [PDF]
Comparative Economic Studies, 2009 Using Solow-Tornqvist residuals as well as two alternative measurements, we present estimates of total factor productivity (TFP) growth in a sample of 30 European economies for the period 1994-2005. In most of Western Europe, we nd a deceleration of TFP growth since 2000. However, the economies of New Europe exhibit a higher level of TFP growth overall

Monitoring Old Growth in Frequent-fire Landscapes
Ecology and Society, 2007 In this article, we discuss how to monitor the structural and functional attributes of old growth, as well as its associated plant communities and wildlife, both to determine the possible need for treatment and to assess post-treatment progress toward ...

Vital rates and their multidecadal trends in the fir-beech old-growth forest of Badínsky prales
Journal of Forest Science, 2023 The study aimed to quantify annual mortality and recruitment rates on permanent research plots in the Badínsky prales old-growth forest. The data measured in four stands originate from six censuses, which together cover a 48-year period.

Structural dynamics of deciduous mixed stands in the Hyrcanian forests, northern Iran
Notulae Botanicae Horti Agrobotanici Cluj-NapocaForest structure as an effect of forest dynamics can be used to characterize biophysical processes, biodiversity and ecosystem functions. This study examines the structural components of old-growth forest stands located in the Caspian forests, north of ...

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Managing for Old Growth in Frequent-fire Landscapes
Ecology and Society, 2007 There is no one-size-fits-all approach to managing frequent-fire, old-growth forests. However, there are general guidelines to follow: 1) set objectives for both structure (tree density, diameter distribution, tree species composition, spatial ...
