MODERATE SEVERITY DISTURBANCE HAS SIMILAR EFFECTS ON THE PRODUCTION OF THREE FORESTS NESTED WITHIN THE UPPER GREAT LAKES LANDSCAPE [PDF]

, 2017
Moderate severity disturbances, which only kill a subset of canopy trees (e.g., via insects, pathogens, and windthrow), are increasingly widespread, and can alter forest structure and production.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Episodic Canopy Structural Transformations and Biological Invasion in a Hawaiian Forest

Frontiers in Plant Science, 2017
The remaining native forests on the Hawaiian Islands have been recognized as threatened by changing climate, increasing insect outbreak, new deadly pathogens, and growing populations of canopy structure-altering invasive species.

Too Hot to Profit? Climatic Stress and Farm‐Level Performance in Italian Viticulture

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates the economic impact of long‐run climatic conditions on Italian wine farms by applying a Ricardian framework to 1431 firms from the 2022 RICA‐FADN survey. We combine farm‐level revenues with viticulture‐specific agroclimatic indicators to assess how climate stress shapes profitability across 77 Italian NUTS3 provinces ...

Coupling Fine-Scale Root and Canopy Structure Using Ground-Based Remote Sensing

Remote Sensing, 2017
Ecosystem physical structure, defined by the quantity and spatial distribution of biomass, influences a range of ecosystem functions. Remote sensing tools permit the non-destructive characterization of canopy and root features, potentially providing ...

Tree phyllosphere bacterial communities: exploring the magnitude of intra- and inter-individual variation among host species [PDF]

PeerJ, 2016
Background The diversity and composition of the microbial community of tree leaves (the phyllosphere) varies among trees and host species and along spatial, temporal, and environmental gradients.

Using ICESAT\u27s geoscience laser altimeter system to assess large scale forest disturbance caused by Hurricane Katrina [PDF]

, 2009
We assessed the use of GLAS data as a tool to quantify large-scale forest damage. GLAS data for the year prior to and following Hurricane Katrina were compared to wind speed, forest cover, and MODIS NPV maps to analyze senor sampling, and changes in mean

The influence of vegetation on turbulence and flow velocities in European salt-marshes

, 2006
Flow hindrance by salt-marsh vegetation is manifested in the structure of the tidal current; it has a significant impact on sediment transport and it has been related to increased sediment accretion. The flow characteristics in three different vegetation

Zero Deforestation Commitments and Industry 4.0 Enabling Technologies: An Analysis of Their Role in Mitigating Deforestation

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines the role of corporate zero‐deforestation commitments (ZDCs) and Industry 4.0 (I4.0) enabling technologies in mitigating deforestation. Drawing on data from 110 companies included in the Forest 500 dataset, the research explores whether sustainability commitments and digital innovation influence firms' deforestation ...

Resolving the internal magnetic structure of the solar network

, 2012
We analyze the spectral asymmetry of Stokes V (circularly polarized) profiles of an individual network patch in the quiet Sun observed by Sunrise/IMaX. At a spatial resolution of 0.15"-0.18", the network elements contain substructure which is revealed by
