In the last decades, illegal logging has posed a serious threat for the integrity of forest ecosystems and for biodiversity conservation in tropical Africa. Although international treaties and regulatory plans have been implemented to reduce illegal logging, much of the total timber volume is harvested and traded illegally from tropical African forest regions. As a result, the development and the application of analytical tools to enhance the ...

Short report of the field mission in RDC Kahuzi Biega national Parc (RDC, 21/4/2022 – 6/5/2022)

Fusarium is one of the most important fungal genera of plant pathogens that affect the cultivation of a wide range of crops. Agricultural losses caused by Fusarium oxysporum f. sp. cubense (Foc) directly affect the income, subsistence, and nourishment of thousands of farmers worldwide. For Viet Nam, predictions on the impact of Foc for the future are dramatic, with an estimated loss in the banana production area of 8% within the next five years ...

Assisted gene flow interventions such as plant translocations are valuable complementary techniques to habitat restoration. Bringing new genetic variants can contribute to increasing genetic diversity and evolutionary resilience, counteract inbreeding depression and improve plant fitness through heterosis. Large, highly genetically variable populations are usually recommended as sources for translocation. Unfortunately, many critically ...

During a survey of polypores in the montane forest of the Obo de Sao Tome National Park, in the western African, equatorial island of Sao Tome, a specimen that was, a priori, related to Fomitopsis showed deviating features including subglobose basidiospores with a large gutta. The gross morphology of the basidiome, the hyphal system, the subglobose basidiospores and a brown rot pointed toward Niveoporofomes. Phylogenetic inferences based on ...

Fungi are a large and hyper-diverse group with major taxa present in every ecosystem on earth. However, compared to other eukaryotic organisms, their diversity is largely understudied. Since the rise of molecular techniques, new lineages are being discovered at an increasing rate, but many are not accurately characterised. Access to comprehensive and reliable taxonomic information of organisms is fundamental for research in different disciplines ...

Sutorius is a poroid genus in Boletaceae that typically has chocolate brown to reddish brown or purplish brown basidiomata with a finely scaly stipe and produces a reddish-brown spore deposit. During the survey on diversity of boletes in northern and northeastern Thailand, several Sutorius collections were obtained. Combined evidence from morphology and phylogenetic analyses of a three-genes data set (atp6, tef1 and rpb2) of the Sutorius ...

Ostropales sensu lato is a large group comprising both lichenized and non-lichenized fungi, with several lineages expressing optional lichenization where individuals of the same fungal species exhibit either saprotrophic or lichenized lifestyles depending on the substrate (bark or wood). Greatly variable phenotypic characteristics and large-scale phylogenies have led to frequent changes in the taxonomic circumscription of this order. Ostropales ...

Knowing species’ breeding system and mating processes occurring in populations is important not only for understanding population dynamics, gene flow processes, and species' response to climate change, but also for designing control plans of invasive species. Geranium robertianum, a widespread biennial herbaceous species showing high morphological variation and wide ecological amplitude, can become invasive outside its distribution range. A ...

Assisted gene flow by plant translocations is a solution for restoring populations when other measures were unsuccessful. An essential step for preparing the translocations is the selection of populations as seed sources, which should be large, genetically diverse and produce good quality seeds. For asexually propagating species, census population size may largely exceed the number of genotypes, which means that genetic variation may be low, and ...
