Influence of forest machine operator work practices and operator assistance systems on the efficiency of fully mechanized timber harvesting systems
(2023-12-01)Introduction: Fully mechanized harvesting systems consisting of harvesters and forwarders represent state-of-the-art technology within modern timber harvesting operations. The droughts of the past years, consecutive ... -
Morphological variation, proximity to water, comparative venom proteomics and snakebite epidemiology of the medically important Cypriot blunt-nosed viper Macrovipera lebetina lebetina
(2023-09-22)Snakes and humans are in a complex relationship. While snakes are of ecological and economic relevance as rodent predators, thus contributing to food security and public health, venomous species are also of medical importance ... -
Linking China Forest Ecology Development with Power: Cases from 1998 to 2022
(2023-09-22)Since the 1980s, China's forest area has experienced a remarkable recovery, simultaneously promoting the ecological functions of forests in biodiversity conservation and carbon sequestration. China's forest transformation ... -
Flux measurements at the land-atmosphere interface: Extending the theory and implementation of the true eddy accumulation and eddy covariance measurement techniques
(2023-06-28)Interactions between the biosphere and the atmosphere have profound effects on the global climate and the future trajectory of the Earth system. Understanding the dynamics and controls of these interactions requires ... -
New insights into drivers and passengers of tree architecture
(2023-06-27)Individual tree architecture and species composition perform a critical role in many ecological processes and resources a forest offers, such as wood value, biodiversity, and ecosystem stability. The structure and dynamics ... -

(2023-02-01)The present research was performed within the scopes of the DFG Research Training Group 1703 “Resource Efficiency in Interorganizational Networks” and AiF Project GmbH (project No. 16KN065229), which aims at developing a ... -
Investigation of the effects of raw material density and molecular weight of phenolic binders on the properties of lightweight panels based on Paulownia wood
(2023-01-03)Abstract This thesis focuses on different production process conditions of strand boards (SBs), especially with wood species (Paulownia tomentosa) by various adhesive binders (pMDI) and their influence on the properties ... -
Quantifying three-dimensional stand structure of European beech forests along a management gradient
(2022-04-26)Forest structure is of functional importance for ecosystem stability and resilience, as well as for numerous other ecosystem functions and services. In this context, a high structural complexity can have a positive effect ... -
Fruiting body development of Coprinopsis cinerea: Cytology and regulatory factors
(2022-04-11)Coprinopsis cinerea, the gray shagged ink-cap, is a saprotrophic edible basidiomycete that naturally grows on horse dung. Despite richness in nutrients, the typical fast autolysis of the cap of the mushroom during maturation ... -
