    Economic drivers of global fire activity: A critical review
    XV World Forestry Congress, 2-6 May 2022

    The special issue on Fire$: Economics and policy of global fire activities in the journal Forest Policy and Economics, was organized as part of the Task Force initiative of the International Union of Forest Research Organization (IUFRO). The special issue endeavored to provide specific and practical economic guidelines that help deal with the wicked problem of managing wildland fire risks with much needed insights from the global South. We present the critical review of economic drivers of global fire activities with the key insights from other papers in the special issue. Overall decline of global burned area paradoxically hides a number of economic realities that have increased the likelihood and costs of wildfire-caused disasters. We identified global patterns of worsening wildfire risks with the double-exposure to globalization and climate change. Current developments call for a paradigm shift in how we understand and manage wildfires to promote an adaptation-mitigation-resilience strategy. We propose expanding the science-policy interface to global scale with new indicators for assessing and communicating the impacts of global economic drivers on wildfire activities. We also identified the areas where research is lacking, highlighting future research areas in wildfire economics to advance effective, efficient, and equitable global governance of wildfires.

    Wood transcriptome analysis of Pinus densiflora identifies genes critical for secondary cell wall formation and NAC transcription factors involved in tracheid formation

    Although conifers have significant ecological and economic value, information on transcriptional regulation of wood formation in conifers is still limited. Here, to gain insight into secondary cell wall (SCW) biosynthesis and tracheid formation in conifers, we performed wood tissue-specific transcriptome analyses of Pinus densiflora (Korean red pine) using RNA sequencing. In addition, to obtain full-length transcriptome information, PacBio single molecule real-time (SMRT) iso-sequencing was carried out using RNAs from 28 tissues of P. densiflora. Subsequent comparative tissue-specific transcriptome analysis successfully pinpointed critical genes encoding key proteins involved in biosynthesis of the major secondary wall components (cellulose, galactoglucomannan, xylan, and lignin). Furthermore, we predicted a total of 62 NAC (NAM, ATAF1/2 and CUC2) family transcription factor members and identified seven PdeNAC genes preferentially expressed in developing xylem tissues in P. densiflora. Protoplast-based transcriptional activation analysis found that four PdeNAC genes, homologous to VND, NST and SND/ANAC075, upregulated GUS activity driven by an SCW-specific cellulose synthase promoter. Consistently, transient overexpression of the four PdeNACs induced xylem vessel cell-like SCW deposition in both tobacco (Nicotiana benthamiana) and Arabidopsis leaves. Taken together, our data provide a foundation for further research to unravel transcriptional regulation of wood formation in conifers, especially SCW formation and tracheid differentiation.

    Wild foods and the way forward: Insights from South and Southeast Asia
    XV World Forestry Congress, 2-6 May 2022

    Forests are regarded for their ecosystem benefits and provision of resources, one of which is food. An important yet often overlooked aspect is the role of forests for food, particularly wild food, in ensuring food security and resilience in the face of climate change, challenges to tenure, forest degradation, and deforestation. This is mostly due to lack of access to information on the nutritive values of forest foods and the array of available edible food from the wild.

    The Living Marine Resources of the Eastern Central Atlantic. Volume 3: Bony fishes part 1 (Elopiformes to Scorpaeniformes) 2016
    Also available in:
    No results found.

    This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Eastern Central Atlantic. The area of coverage includes FAO fishing area 34 and part of 47. The marine resource groups included are bivalves, gastropods, chitons, cephalopods, stomatopods, shrimps, lobsters, crabs, hagfishes, sharks, batoid fishes, chimaeras, bony fishes and sea turtles. The introductory chapter outlines the environmental, ecological, and biogeographical factors influencing the marine biota, and the basic components of the fisheries in the Eastern Central Atlantic. Within the field guide, the sections on the re source groups are arranged phylogenetically according to higher taxonomic levels such as class, order, and family. Each resource group is introduced by general re marks on the group, an illustrated section on technical terms and measurements, and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, bi o logical and fisheries in formation, notes on similar families occur ring in the area, a key to species, a check list of species, and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no de tailed species in formation. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar specie s, an illustration, FAO common name(s), diagnostic characters, biology and fisheries in formation, notes on geo graphical distribution, and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map, and notes on biology, fisheries, and distribution. Each volume concludes with its own index of scientific and common names.
