{"title":"Alan Orange – an appreciation, 19th June 1955–5th February 2023","authors":"P. Wolseley, R. Woods, J. Douglass, Brian J. Coppins, G. Peterken","doi":"10.1017/S0024282923000245","DOIUrl":"https://doi.org/10.1017/S0024282923000245","url":null,"abstract":"Alan Orange, who died on the 5th February aged only 67, will be missed more than he would ever have guessed by members of the British Lichen Society and lichenologists across the globe. He was an outstanding naturalist and taxonomist who made detailed studies of difficult groups of organisms, from lichens and bryophytes to mites. His knowledge of sterile crusts and aquatic lichens was unrivalled. He investigated every aspect of his chosen organisms, from their morphology to their chemistry and genetics, in order to describe them taxonomically and to assess their relationships to other lichens. Alan was born in Leeds but soon afterwards the family moved to Longhope in the Forest of Dean, where his surroundings provided plenty of opportunities for botanical and other exploration, often with his cousins Heather, Margaret and Stephen, and the family’s dogs. Early on he developed his botanical skills and his taste for sorting out difficult groups of organisms, and his parents complained that his collection of brambles had taken over his bedroom! He also showed exceptional talent as an artist, producing detailed botanical drawings and sketches which he continued for the rest of his life. He was accepted for his first degree in Science at Bristol University and then for a master’s degree in Pure and Applied Plant Taxonomy at Reading University, which he completed with distinction. After graduating in the early 1980s, he worked as a field botanist based at the University of Wales Institute of Science and Technology field centre at Newbridge-on-Wye, Powys. Tasked with undertaking botanical survey work on the upper reaches of the Rivers Wye, Usk, Severn and Teifi, this tall, immensely quiet but undoubtably talented character with hair below his waist rejected the proffered car to drive. Instead, a motorbike was acquired. As part of a very successful team, he helped lay the foundation for the science behind the statutory conservation of rivers and so began his own fascination with the hugely variable community of aquatic lichens. In 1977, while still an undergraduate, Alan was employed by the Nature Conservancy to survey the trees and flora in the permanent transects within Lady Park Wood in the Lower Wye Valley. The resulting records were so neat, thorough and accurate that they have been used as a basis for all subsequent recording. This, now possibly the largest and most enduring long-term study in Europe of how natural woodlands behave, would have been abandoned in its youth without Alan’s contribution. When he returned in 2014 to check the lichens for the Lady Park book (Peterken & Mountford 2017), he appeared to have no idea his work had been so significant. In 1986 he was appointed Curator of Lichens at the National Museum of Wales (NMW), now Amgueddfa Cymru-Museum Wales. His talent for illustration was quickly put to good use, producing a useful beginner’s guide to lichens on trees (Orange 1994). He held the post of curator until 2013 when he became","PeriodicalId":18124,"journal":{"name":"Lichenologist","volume":"55 1","pages":"103 - 106"},"PeriodicalIF":1.4,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48652699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analyses of the nrDNA ITS and nuLSU regions revealed that it clustered within the genus Anamylopsora. Further chemical and morpho-anatomical analyses confirmed its uniqueness, and it is described here as a new species under the name A. pakistanica. The distinguishing characters are: an irregularly squamulose appressed thallus on rocks without rhizines; an epinecral layer up to 25 μm thick; ascospores that are hyaline, simple, thick-walled with a smooth surface; septate paraphyses with a pigmented apical cell in a gel-like matrix; globose to subglobose pycnidia with hyaline and bacilliform pycnidiospores. In particular, the species is distinguished from other members of the genus by morpho-anatomical features including the coloration of the thalli, the presence of a thick lower cortex (up to 100 μm), and the presence of simple, thick-walled ascospores. Specimens were found at altitudes up to 4587 m, the highest elevation yet reported for Anamylopsora.

We developed and tested new microsatellites for the nitrophilic lichenized fungus Xanthoria parietina and studied its genetic diversity and structure within the urban area of Munich, Bavaria. We compared its local genetic pattern with that of its photobiont partner Trebouxia decolorans, for which existing microsatellites were applied. For comparison, a reference site with clean air was included in the sampling. We found support for three genetic clusters in the fungus X. parietina, which occurred intermingled in collecting sites. There was a high degree of admixture within fungal populations and individuals, and analysis of molecular variance revealed a lack of population structure in the mycobiont. The Trebouxia photobiont, in contrast, exhibited structured populations which grouped into two to five genetic clusters, and individuals showed less admixture than in the mycobiont. This indicates that the two lichen partners differ in their ability to move around in the landscape. The microsatellite markers we report are polymorphic and are suitable for population genetic studies.","PeriodicalId":18124,"journal":{"name":"Lichenologist","volume":"55 1","pages":"69 - 79"},"PeriodicalIF":1.4,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42263142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
