    Vertebral number is highly evolvable in salamanders and newts (family Salamandridae) and variably associated with climatic parameters (2015)

    Description: In vertebrates, the relative proportion of the number of trunk and caudal vertebrae is an important determinant of body shape. While among amphibians frogs and toads show low variation in vertebrae numbers, in salamanders the numbers of trunk and caudal vertebrae vary widely, giving rise to phenotypes in the range from short-bodied and long-tailed to long-bodied and short-tailed. We analysed vertebral numbers in the family Salamandridae in a phylogenetic context and calculated the relationship between vertebral changes and changes in climate and other environmental parameters. A significant association was found between morphological change with precipitation and temperature. However, annual precipitation affected the two main groups of salamandrid salamanders differently, with trunk elongation in the terrestrial \xe2\x80\x98true salamanders\xe2\x80\x99 and tail elongation in the more aquatic \xe2\x80\x98newts\xe2\x80\x99. A - male biased - sexual dimorphism was only observed in Lissotriton vulgaris vulgaris in the number of trunk vertebrae and in Ommatotriton ophryticus and Lissotriton species for the number of caudal vertebrae. Our data indicated that the number of trunk and caudal vertebrae are highly evolvable traits with frequent evolutionary reversals. In some groups (e.g. Cynops, Lyciasalamandra, Neurergus and the Laotriton-Pachytriton-Paramesotriton clade) the number of trunk vertebrae is stable, while in many groups it is subject to change (e.g. Tylototriton). This latter, species-rich genus appears to be an excellent group to further test effects of the environment on body shape.

    The Emerging Field of Geoethics (2018)
    John Wiley & Sons, Inc. - American Geophysical Union
    Details
    Publication Date: 2019-03-27
    Description: The geosciences need practitioners who possess an ethical conscience and the desire to act responsibly. Ethically responsible geoscientists will achieve success and satisfaction by carrying out excellent research and professional activities, and by maintaining honest and open collaborations with colleagues. Such individuals will be able to contribute to building a resilient society, be better prepared to face global economic and environmental challenges and be willing to take concrete actions for the conservation of the geo‐environment. Geoethics provides ethical, social, and cultural values for the scientific community and for society as a whole. Geoethics represents a new vision of a world in which it is possible to maintain a more balanced relationship between humans and nature, considering modern economic and social development expectations. This chapter illustrates some aspects of geoethics, provides an overview of its basic values and themes, and highlights prominent global issues that involve geoethics, including climate change, geo‐risks, land management, exploitation of geo‐resources, and sustainability. The International Association for Promoting Geoethics (IAPG) provides a multidisciplinary platform for discussion, a place where multidisciplinary collaboration can strengthen the development of geoethics from a scientific and philosophical perspective, in order to better introduce geoethical values into society.

    Malassezia vespertilionis sp. nov.: a new cold-tolerant species of yeast isolated from bats (2018)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 41, pp. 56-70
    Details
    Publication Date: 2024-01-12
    Description: Malassezia is a genus of medically-important, lipid-dependent yeasts that live on the skin of warmblooded animals. The 17 described species have been documented primarily on humans and domestic animals, but few studies have examined Malassezia species associated with more diverse host groups such as wildlife. While investigating the skin mycobiota of healthy bats, we isolated a Malassezia sp. that exhibited only up to 92 % identity with other known species in the genus for the portion of the DNA sequence of the internal transcribed spacer region that could be confidently aligned. The Malassezia sp. was cultured from the skin of nine species of bats in the subfamily Myotinae; isolates originated from bats sampled in both the eastern and western United States. Physiological features and molecular characterisation at seven additional loci (D1/D2 region of 26S rDNA, 18S rDNA, chitin synthase, second largest subunit of RNA polymerase II, \xce\xb2-tubulin, translation elongation factor EF-1\xce\xb1, and minichromosome maintenance complex component 7) indicated that all of the bat Malassezia isolates likely represented a single species distinct from other named taxa. Of particular note was the ability of the Malassezia sp. to grow over a broad range of temperatures (7\xe2\x80\x9340 \xc2\xb0C), with optimal growth occurring at 24 \xc2\xb0C. These thermal growth ranges, unique among the described Malassezia, may be an adaptation by the fungus to survive on bats during both the host\xe2\x80\x99s hibernation and active seasons. The combination of genetic and physiological differences provided compelling evidence that this lipid-dependent yeast represents a novel species described herein as Malassezia vespertilionis sp. nov. Whole genome sequencing placed the new species as a basal member of the clade containing the species M. furfur, M. japonica, M. obtusa, and M. yamatoensis. The genetic and physiological uniqueness of Malassezia vespertilionis among its closest relatives may make it important in future research to better understand the evolution, life history, and pathogenicity of the Malassezia yeasts.

    Six new Phytophthora species from ITS Clade 7a including two sexually functional heterothallic hybrid species detected in natural ecosystems in Taiwan. (2017)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 38, pp. 100-135
    Details
    Publication Date: 2024-01-12
    Description: During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, \xc3\x9f-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. Four homothallic species, P. attenuata, P. flexuosa, P. formosa and P. intricata, were isolated from rhizosphere soil of healthy forests of Fagus hayatae, Quercus glandulifera, Q. tarokoensis, Castanopsis carlesii, Chamaecyparis formosensis and Araucaria cunninghamii. Two heterothallic species, P. xheterohybrida and P. xincrassata, were exclusively detected in three forest streams. All P. xincrassata isolates belonged to the A2 mating type while isolates of P. xheterohybrida represented both mating types with oospore abortion rates according to Mendelian ratios (4\xe2\x80\x9333 %). Multiple heterozygous positions in their ITS, \xc3\x9f-tubulin and HSP90 gene sequences indicate that P. xheterohybrida, P. xincrassata and P. cambivora are interspecific hybrids. Consequently, P. cambivora is redescribed as P. xcambivora without nomenclatural act. Pathogenicity trials on seedlings of Castanea sativa, Fagus sylvatica and Q. suber indicate that all six new species might pose a potential threat to European forests.
