Diversity of hindgut symbiotic flagellate protist communities of the European subterranean termite in Portugal
2016 - IRG/WP 16-10875
The flagellate protist communities are an important part of the termite, as they lead the lignocellulose digestion. Termites (Reticulitermes grassei) were sampled from forest and urban environments in mainland Portugal where they are native and in Faial Island, Azores (invasive populations). Termites’ gut contents was analysed morphologically and the diversity of the flagellate protist community...

Effects of geographical and dietary variation on the symbiotic flagellate protists communities of the subterranean termite Reticulitermes grassei Clément
2015 - IRG/WP 15-10847
Despite their importance on diverse ecosystems, termites may also be considered severe pests of wood in service, and also as agricultural and forestry pests.
Subterranean termites’ ability to digest lignocellulose relies not only on their digestive tract physiology, but also on the symbiotic relationships established with flagellate protists and bacteria. In this tripartite lignocellulolytic sy...

Reticulitermes (Ins., Isopt.) in Central and Western Europe
1969 - IRG/WP I 5A
Reticulitermes flavipes (Kollar) has established itself in Hamburg and Hallein coming from the east of North America. In France, on the northern boundary of termit occurrence, Reticulitermes santonensis are distinguished from Reticulitermes lucifugus by special activity and resistance. According to comparative investigations with colonies of several Reticulitermes species of different origins rega...

Reticulitermes (Ins., Isopt.) in Mittel- und West-Europa
1969 - IRG/WP I 4
In Hamburg und Hallein hat sich Reticulitermes flavipes (Kollar) aus dem Osten von Nordamerika eingebürgert. An der Nordgrenze des Termitenvorkommens im Westen Frankreichs zeichnet sich Reticulitermes santonensis Fetaud gegenüber Reticulitermes lucifugus durch besondere Aktivität und Widerstandsfähigkeit aus. Nach vergleichenden Untersuchungen an Kolonien verschiedener Reticulitermes-Arten meh...

Effects of two wood preservatives and one water repellant on the settlement of fouling communities in a tropical marine environment
2002 - IRG/WP 02-30293
Observations made on recruitment of fouling organisms on treated panels exposed at an Indian harbour, Krishnapatnam on the east coast (Lat: 13028’ to 13059’ N; Long: 80010’ to 80016’ E) during November, 1997 to October, 1999 are reported and compared with fouling communities on control panels. Wooden panels of Erythrina variegata, Paraserianthus falcataria, Tetrameles nudiflora an...

Effects of chlorothalonil (CTN) and butylated hydroxytoluene (BHT) on microbial communities involved in the deterioration of wood using T-RFLP I: Accelerated laboratory decay study
2006 - IRG/WP 06-20332
The effects of Chlorothalonil (CTN) and Butylated Hydroxy Toluene (BHT) on microbial species diversity in wood and the surrounding soil are being assessed by Terminal Restriction Fragment Length Polymorphism (T-RFLP). CTN was selected as a trial organic wood preservative, and BHT is being evaluated for its synergistic effects with CTN. Results from an accelerated decay test will be presented. The...

Effects of chlorothalonil (CTN) and butylated hydroxytoluene (BHT) on microbial communities involved in the deterioration of wood using T-RFLP II: Results from field studies
2007 - IRG/WP 07-30429
The effects of Chlorothalonil (CTN) and Butylated Hydroxytoluene (BHT) on microbial species diversity in wood and the surrounding soil are being assessed by Terminal Restriction Fragment Length Polymorphism (T-RFLP). CTN was selected as a trial organic wood preservative, and the non-biocidal BHT was evaluated for its synergistic effects with CTN. ACQ-C was a positive control and untreated SYP sta...

Biodegration of treated wood waste by native fungal communities of tropical soil in French Guiana
2012 - IRG/WP 12-50285
Woods have been protected with fungicides for a long time, and the effects of these fungicides on soil after being leached into the ground have turned out to be a true environmental issue. It is in this perspective that we are proposing to study fungal communities of these contaminated woods in a purpose of bioremediation. Most of precedent studies have focused on ability of some Basidiomycetes an...

Tar-oil uptake vs time in immersion treatment of short pine posts: A simple technique applicable to rural communities of Papua New Guinea
2012 - IRG/WP 12-40608
Pinus caribaea and Araucaria cunninghamii logs ca. 100 mm in diameter were shortened to lengths 25-30 cm, conditioned to at/below fibre saturation point (FSP) for immersion/dip treatment using a hot- and- cold bath open- tank process. Before oven-drying and subsequent treatment, individual test specimens were numbered, their green weights and volumes, and dry weights recorded for basic density, vo...

Communities of mold fungi on flooded building materials
2013 - IRG/WP 13-10799
A small building built to residential code was flooded using farmland pond water to a depth of two feet at Tuskegee University. The building was drained and left enclosed for an additional three weeks. A total of 168 material samples were removed either immediately after opening (wet) or seven months after flooding (dry). Wall materials sampled included fiberglass batt insulation, gypsum wallboard...

High-throughput sequencing highlighted contrasted pioneer fungal communities associated to coniferous and deciduous wood preservation assays
2013 - IRG/WP 13-10800
Studying the fungal communities in the wood, in particular during the first events of the colonization, and the factors that underlie the dynamics of fungal species assemblages remain a challenge in ecology, because of the absence of fructification during the pioneer steps of wood degradation. The use of Next-generation DNA sequencing methods, which produce massive volumes of data, provided new pe...

Communities of mold fungi in moisture damaged building materials
2014 - IRG/WP 14-20542
The critical conditions needed for the development of mould and decay fungi have been modelled for different building materials. However, current knowledge of indoor microbes growing on building materials relies on culture-based methods and more advanced molecular biological techniques should be employed to study the complex microbial communities in building materials. In this paper molecular biol...

Response of the symbiotic flagellate protists community of subterranean termites to sublethal amounts of biocides
2018 - IRG/WP 18-10911
Subterranean termites are quite efficient at extracting nutrients from lignocellulose. Their ability relies not only on the digestive tract physiology but also on symbiotic relationships established with flagellate protists and bacteria. This work aimed to screen the response of the flagellate protists community of the subterranean termite Reticulitermes grassei Clément to the ingestion of differ...

Characterization of the fungal communities associated with Aquilaria crassna Pierre ex Lecomte plantations in French Guiana
2023 - IRG/WP 23-11001
Aquilariais a tree species belonging to the family of the Thymeleaceae. When the tree is wounded, it can produce a blackened wood, also known as agarwood. The blackened wood has a darker colour than healthy wood and gives off a strong fragrance greatly appreciated by perfumers and by certain oriental religious communities. Production of this blackened wood is deemed to depend on environmental fact...
