Calibration of LAI-2000 to estimate leaf area index (LAI) and assessment of its relationship with stand productivity in six native and introduced tree species in Costa Rica

open access: yesForest Ecology and Management, 2007
Abstract Leaf area index (LAI) is one of the most frequently used parameters for the analysis of canopy structure and it has also been shown to be an important structural characteristic of the forest ecosystem and forest productivity. The objectives of this study were: (1) to calibrate optical estimates of PAI (plant area index) from the LAI-2000 ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

open access: yesBiotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Estimación del índice de área foliar en pinares de repoblación con LAI-2000 bajo radiación solar directa: relación con variables de inventario e hidrológicas

open access: yesForest Systems, 2011
El índice de área foliar (LAI) es una variable clave en los procesos de intercepción de la lluvia y la luz en masas forestales y por tanto tiene gran potencial en la práctica de la selvicultura adaptativa al cambio climático, de ahí la necesidad de establecer tanto metodologías sencillas para su estimación, como su relación con las principales ...

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.
