Abstract Purpose of the Review The application cut-to-length (CTL) technology for harvesting and processing timber from broadleaved tree species is a challenging process, due to thick branches, stem sweep, forks high wood density. objective this review was describe current state harvester use characterise effectiveness mechanised forest operations mixed stands in Europe, paying particular atten...

In order to determine the impact of forest conversions on labile organic carbon fractions, soils at depths of 0 10, 10 30 and 30 50 cm were collected from three types of forest: secondary monsoon evergreen broadleaved forest (BF), mixed pine and broadleaved forest (MF) and Masson pine forest (PF) in subtropical China. The light fraction organic carbon (LFOC), particulate organic carbon (POC) an...

A study was carried out over a two year period (2009/2010 and 2012/2013) on an experimental farm in the Alentejo region (Beja), in southern Portugal where rainfed malt barley (Hordeum distichum L.) is sown at the end of autumn or beginning of winter (November–December). The aim of this experiment was to study the efficiency of the herbicide iodosulfuron-methyl-sodium to control post-emergence b...

A search for energy efficient, non-herbicide weed control methods led to development of a novel electrical weeding technology. This study focuses on efficiency and as elements system that would include machine vision robotics escape weeds in field crops. Two pulse generation systems, one single multiple, were developed evaluated at different delivered voltages energies. Greenhouse trials using ...

The paper deals with the "Estimation of growth and yield" included in the National Programme on Intensive Monitoring of Forest Ecosystems CONECOFOR Aims of the paper are: i) to outline the composition and design of Level II PMPs network, also examining the structural characteristics of forest stands; ii) to describe the contents of mensurational surveys carried out in winter 1996/97 and 1999/00...

Discovering how to best protect one of the most endangered animals in the world, giant pandas, has always been an important project in ecological studies. Moreover, researching the living environments of giant pandas and how to recover them is one of the most important elements to these studies. In order to more effectively protect the giant pandas and their habitats, we studied the changing of...

Quantitative relationships between stand indices and carbon dioxide (CO2) stocking are missing in the evergreen broadleaved forests (EBLFs) in eastern China and this hinders to estimate carbon (C) budget in the subtropical region. We determined the vegetation-soil C pool and CO2 stocking using stand indices [diameter at breast height (DBH), total height (H) and wood density] in Schima superba d...

Larval habitat for three highland Anopheles species: Anopheles albimanus Wiedemann, Anopheles pseudopunctipennis Theobald, and Anopheles punctimacula Dyar and Knab was related to human land uses, rivers, roads, and remotely sensed land cover classifications in the western Ecuadorian Andes. Of the five commonly observed human land uses, cattle pasture (n = 30) provided potentially suitable habit...
