Coming up short: Identifying substrate and geographic biases in fungal sequence databases
(Journal article; Peer reviewed, 2018-09-22)Insufficient reference database coverage is a widely recognized limitation of molecular ecology ap-proaches which are reliant on database matches for assignment of function or identity. Here, we use datafrom 65 amplicon ... -
A common Nordic-Baltic costing framework for road, rail and sea transport of roundwood
(NIBIO-rapport;7(8) 2021, Research report, 2021-01)Transport cost calculations are fundamental for most types of transport research. Applications can range from estimating the cost benefits of developing transport technologies (e.g. increased truck GVWs) to comparing ... -
Communication in a changing world. Increasing the impacts and benefits of scientific research activities.
(Bioforsk Rapport; 7(73) 2012, Research report, 2012)The overall goal is to professionalize and strengthen the disseminating and communicating elements of protected areas in Vietnam in order to increase the impacts of projects, and to establish a set of “best practise” ... -
Comparative analysis of data frameworks for agricultural policy analysis. The WTO‐notifications and the OECD’s PSE database
(NILF Discussion Papers;2012-4, Research report, 2012-04)Both the OECD and the WTO have accumulated systematic data on the magnitude of support going to farmers as a result of farm policies. The datasets are collected for different purposes but both give a detailed picture of ... -
A Comparative Analysis of Five Forest Certification Programs
(Peer reviewed; Journal article, 2020-08-08)International expansion of forest certification programs has occurred over the last three decades. Both public and private organizations have shown increased interest in becoming certified by one or more forest certification ... -
