Old-growth and secondary Araucaria Forest characterization
Trees, Forests and People, 2022 The Araucaria Forest is one of the most threatened ecosystems in Brazil due to selective logging and deforestation, mainly during the 20th century. The great majority of remnants are secondary forests with less than 50 ha, i.e., old-growth fragments are ...

Using the old-growth concept to identify old species-rich semi-natural grasslands
Ecological Indicators, 2023 The concept of ‘old growth’, originally developed for forests, was recently extended to grassland to distinguish old natural grasslands (NG) from semi-natural grassland (SNG).

The role of reductions in old-age mortality in old-age population growth
Demographic Research, 2021 Background: The variable-r model provides demographers with a way to explore the contributions of demographic components (fertility, mortality, migration) to changes in populations' age structures.

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.
