Fungi play major roles in ecosystem processes, but the determinants of fungal diversity and biogeographic patterns remain poorly understood. Using DNA metabarcoding data from hundreds globally distributed soil samples, we demonstrate that richness is decoupled plant diversity. The plant-to-fungus ratio declines exponentially toward poles. Climatic factors, followed by edaphic spatial variables, constitute best predictors community composition at global scale. show similar latitudinal...

Abstract The ambrosia beetle morphologically identified as E uwallacea fornicatus consists of several cryptic species that exhibit large differences in the DNA sequences nuclear and mitochondrial gene regions. Based on these differences, we suggest there are at least three different each with distinct phylogeography. Members this complex have invaded many areas outside their native range cause substantial damage to both agriculture (avocado particular) other tree species. Three USA : two C...
Fusarium euwallaceae is a well-characterized fungal symbiont of the exotic ambrosia beetle Euwallacea sp. (polyphagous shot hole borer [PSHB]), together inciting dieback on many host plants in Israel and California. Recent discoveries additional symbionts within mycangia suggest these fungi occur as communities. Colony-forming units Graphium nov. Paracremonium pembeum nov., two novel associates PSHB from California, grew 36 macerated female heads gallery walls collected Platanus racemosa,...
Novel species of microfungi described in the present study include following from Australia: Catenulo stroma corymbiae Corymbia, Devriesia stirlingiae Stirlingia, Penidiella carpentariae Carpentaria, Phaeococcomyces eucalypti Eucalyptus, Phialophora livistonae Livistona, Phyllosticta aristolochiicola Aristolochia, Clitopilus austroprunulus on sclerophyll forest litter Eucalyptus regnans and Toxicocladosporium posoqueriae Posoqueria.Several are also South Africa, namely: Ceramothyrium podo...
Abstract Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A picture variations in peat organic matter chemistry aid our ability gauge peatland response climate. The goal this research test hypotheses that (a) carbohydrate content, an indicator reactivity, increase with latitude and decrease mean annual temperatures, (b) while aromatic recalcitrance, vary inversely, (c) elevation have...
Various hypotheses have been proposed regarding the origin of plant pathogen Phytophthora cinnamomi. P. cinnamomi is a devastating, highly invasive soilborne associated with epidemics agricultural, horticultural and forest plantations native ecosystems worldwide. We conducted phylogeographic analysis populations this sampled in Asia, Australia, Europe, southern northern Africa, South America, North America. Based on genotyping-by-sequencing, we observed highest genotypic diversity Taiwan...
The planted forest area in Vietnam increased from 3.0 to 4.4 million hectares the period 2010–2020, but loss of productivity pests and diseases continues be a problem. During this period, frequent systematic plantation health surveys were conducted on 12 native 4 exotic genera trees as well bamboo across eight geographic regions Vietnam. Damage caused by insects pathogens was quantified field laboratory Hanoi. threats greatest concern folivores (Antheraea frithi, Arthroschista hilaralis,...
The gall wasp, Leptocybe invasa, is a devastating pest of eucalypt plantations, woodlots, and urban trees in the Middle East, Mediterranean basin, Africa, India, South-East Asia, China.It was first observed Israel 2000 has since spread rapidly south east.It reached southern Vietnam 2002 moved northward nurseries young plantations.Eighteen species eucalypts were selected for sentinel trial northern to determine their susceptibility pathogens region.They also rated impact invasa.Leptocybe...
Peatlands account for 15 to 30% of the world’s soil carbon (C) stock and are important controls over global nitrogen (N) cycles. However, C N concentrations known vary among peatlands contributing uncertainty inventories, but there few studies that relate peatland classification peat chemistry. We analyzed 436 cores sampled in 24 countries across six continents measured C, N, organic matter (OM) content at three depths down 70 cm. Sites were distinguished between northern (387) tropical (49)...
The impact of invasive plant species in national parks and forests Vietnam is undocumented management plans have yet to be developed. Ten parks, ranging from uncut degraded located throughout Vietnam, were surveyed for species. Transects set up along roads, trails where local people access park areas, also tracks through natural forest. Of 134 exotic weeds, 25 classified as the number ranged 8 15 per park. An assessment risk was made three based on an protocol. Examples highly Chromolaena...

Abstract Chukrasia tabularis A. Juss produces a valuable timber but plantations are susceptible to attack by the shoot-tip borer Hypsipyla robusta Moore. An integrated pest management (IPM) approach is desirable limit extent of damage. Therefore, this study was undertaken evaluate deployment IPM measures in Vietnam. Data on tree damage and biology H. were gathered 4 provinces over one year used build an investigation schedule. Two preliminary trials then established which Bacillus...
