Relationship between tree growth and physical dimensions of Fagus sylvatica crowns assessed from terrestrial laser scanning

iForest - Biogeosciences and Forestry, 2015
Measurements of physical tree crown dimensions were of subjective character in the past, even though they can be considered important for the management of many silvicultural operations, such as timing of thinning operations. In our study we investigated

Synergies in Agricultural Biodiversity Conservation: Decomposing the Interaction Between Nature Parks and Agri‐Environment Schemes

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Understanding how policy instruments with overlapping goals interact is crucial for leveraging their synergies. This study explores the mechanisms for regional nature parks (a form of protected areas that impose no restrictions on agriculture) to enhance the adoption of biodiversity‐conserving agri‐environment schemes (AES) in Switzerland ...

Sulphate contamination, pH and conductivity of forest soils in two neighbouring mountains with different pollution in Slovakia from 1989 to 2013

Soil and Water Research, 2018
The Štiavnické vrchy Mts. were strongly affected by pollution mostly from an aluminium plant in 1953-1989. This paper compares contamination of soils between Štiavnické vrchy Mts. and the neighbouring little polluted Kremnické vrchy Mts.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Autumn sunlight promotes aboveground carbon loss in a temperate mixed forest

Ecological Processes
Background Photodegradation of plant litter plays a pivotal role in the global carbon (C) cycle. In temperate forest ecosystems, the exposure of plant litter to solar radiation can be significantly altered by changes in autumn phenology and snow cover ...

The Role of Social Food Infrastructure in Addressing SNAP Participation Gaps: Evidence From Linked Administrative and Ground‐Sourced Data

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We link American Community Survey and SNAP records for 185,000 units with ground‐sourced social food infrastructure data from FindFoodIL (Illinois Extension SNAP‐Ed) to examine SNAP participation determinants among eligible units. Bivariate probit models reveal, beyond SNAP offices, quantity of social infrastructure is associated with ...

Local outbreaks of Operophtera brumata and Operophtera fagata cannot be explained by low vulnerability to pupal predation [PDF]

, 2013
One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do.
