Yahr R. (2015): The status of the conservation priority species Calicium corynellum in the British Isles, Lichenologist, 47(4): 205–214

Conservation organisations are tasked with protection of biodiversity but are challenged by limited resources; consequently, the highest conservation priority species have designations that should correspond with the level of protection needed. In Britain, the saxicolous Calicium corynellum receives the highest conservation priority as a consequence of its rarity, combined with dramatic population declines over the last several decades, having disappeared from 2 of its 4 British sites and declined … Read more...

(2024): Red Listing lichenized fungi: best practices and future prospects, The Lichenologist, 56(6): 345-362

According to International Union for the Conservation of Nature (IUCN) guidelines, all species must be assessed against all criteria during the Red Listing process. For organismal groups that are diverse and understudied, assessors face considerable challenges in assembling evidence due to difficulty in applying definitions of key terms used in the guidelines. Challenges also arise because of uncertainty in population sizes (Criteria A, C, D) and distributions (Criteria A2/3/4c, B). Lichens, which … Read more...

Across much of lowland Britain, lichen diversity has been dramatically affected by the Industrial Revolution, including the lasting legacy of pollution, and changes in land use including the loss, intensification, or abandonment of traditional woodland management. We sampled pre- served epiphytes on historical timbers in vernacular buildings to reconstruct pre-industrial lichen species occurrence for a site in Exmoor, south-west England, and used these data to quantify bio- diversity loss that appears … Read more...

Yahr R., Coppins B.J. & Coppins A.M. (2013): Transient populations in the British conservation priority lichen, Cladonia botrytes, Lichenologist, 45(2): 265–276

In the face of changing environments, conservation is tending towards an adaptive framework which accounts for the movement of species in the landscape. This makes it necessary to quantify population dynamics of species of concern. We studied the nationally scarce Cladonia botrytes, a priority Biodiversity Action Plan species in Britain, examining population dynamics at two scales: first, we studied the demography for two populations over a period of 13 years. The monitored populations declined to … Read more...

Yahr R., Coppins B.J. & Ellis C.J. (2011): Preserved epiphytes as an archaeological resource in pre-industrial vernacular buildings, Journal of Archaeological Science, 38: 1191-1198

The vernacular building tradition is an established source of information about historic woodlands and woodland management in Britain. We build on this resource by recognizing the information content derived from the tree-dwelling epiphyte communities of lichens and mosses, which are preserved on the bark of historic wooden building materials.We report on a first analysis of preserved epiphytes identified from six regions across lowland England. Seventy-eight vernacular buildings were surveyed … Read more...

Yahr R., Florence A., Škaloud P. & Voytsekhovich A. (2015): Molecular and morphological diversity in photobionts associated with Micarea s. str. (Lecanorales, Ascomycota), Lichenologist, 47(6): 403–414

Abstract: Lichenization is a symbiotic ecological strategy that is widely distributed among the fungi, but in which the diversity of partners is relatively poorly known. Limited morphological diversity has hindered the recognition of true diversity in many lichen fungi, and also in their algal partners. In the temperate and boreal zones, the crustose microlichens are the most speciose but arguably the least studied, particularly in terms of their photobiont partners. In this study, we sampled eight … Read more...

Yahr R., Royal Botanic Garden Edinburgh Genome Acquisition Lab, Darwin Tree of Life Barcoding collective et al. (2024): The genome sequence of a lichen-forming fungus, Cladonia squamosa Hoffm. [version 1; peer review: 1 approved, 1 approved with reservations], Wellcome Open Research, 9: 455

We present a genome assembly from a specimen of lichen-forming fungus, Cladonia squamosa (Ascomycota; Lecanoromycetes; Lecanorales; Cladoniaceae). The genome sequence is 38.0 megabases in span. Most of the assembly is scaffolded into 26 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 50.9 kilobases in length. Keywords: Cladonia squamosa, lichen-forming fungus, genome sequence, chromosomal, Lecanorales. Read more...
