Published: September 2023

AbstractAn increasing number of studies are describing the diversity of lichen phycobionts, which is leading to a better understanding of how lichen communities are assembled at different taxonomic, evolutionary and geographical scales. The present study explores the identity and genetic diversity of the microalgal partners of Punctelia borreri and P. subrudecta, two tropical and temperate parmelioid lichen fungi that often grow in temperate and Mediterranean forest ecosystems in Europe. Based on a specimen sampling distributed in two climatically divergent regions in the Iberian Peninsula, we found that these mycobionts are associated with Trebouxia gelatinosa, whose identity was also confirmed by an ultrastructural study of the pyrenoid. The bipartite network analysis indicated that each Punctelia species was associated with a different set of low frequency T. gelatinosa infraspecific lineages, whereas the two most abundant phycobiont lineages were shared between both mycobionts. Based on the current sampling, these two algal lineages occur exclusively in one of the two studied regions, which might point towards climate-driven, fine-tuned fungal-algal interactions. Finally, we documented visible symptoms of injury on the thalli in areas likely to have been impacted by air pollution.

AbstractSpecies of lichen-forming fungi (LFF) display an array of geographical distribution patterns. Among the broadly distributed lichen-forming fungal species, the degree of reproductive isolation and genetic substructure among populations varies widely, in some cases masking unrecognized diversity or meaningful biogeographical patterns. Lecidea atrobrunnea (Raymond ex Lam. & DC.) Schaer. s. lat. (Lecideaceae) is a widespread species complex that has been studied for over two centuries since its initial description. The diversity of the L. atrobrunnea group is highest in western North America, where a dizzying array of morphologies and chemistry can occur at local scales. Here we investigate whether the assumed cosmopolitan distribution of L. atrobrunnea s. lat. is an artifact of taxonomic limitations and masks biogeographical patterns in this species complex. To address these questions, we compiled sequence data from the standard fungal barcoding marker (ITS) for over 100 specimens within this complex, in addition to genome-scale data from a subset of these representing over 1600 single-copy nuclear genes spanning over 3 Mb of the genome. Our study corroborates the perspective that the morphologically and chemically variable Lecidea atrobrunnea group reflects a complex of distinct species-level lineages, with 42–83 candidate species inferred from the ITS region and high levels of diversity inferred from a subset of specimens using genome-scale data. However, both phenotype- and molecular-based species boundaries remained unsettled, with the most common nominal taxa recovered as highly polyphyletic and with conflict among different molecular species delimitation approaches. Our study also highlights the potential for geographically restricted species, with fascinating biogeographical patterns, challenging, in part, the assumed cosmopolitan distribution of L. atrobrunnea s. lat. This study provides valuable direction for future research that will be crucial in understanding diversification and establishing a robust taxonomy for this well-known species complex.
Natura 2000 network enhances the protection of rare epiphytic lichens: evidence from forest sites of Central Italy
Authors: Frati Luisa , Brunialti Giorgio 
Published: September 2023

AbstractAlthough epiphytic lichens are widely adopted as environmental indicators, they are not yet included among the target species listed in Annex II of the Habitats Directive, to which the system of protected areas of the Natura 2000 network refers. In this work, we aim to test the effectiveness of this system, mainly designed for the conservation of other groups of species, in protecting lichen species richness. For this purpose, we considered a case study (Central Italy) with half of the territory included in protected areas. Statistical differences in species richness and lichen communities were tested between sites located in 16 Protected Areas (PA) and 11 Non-Protected Areas (NPA) using non-parametric tests, multi-response permutation procedures (MRPP), non-metric multidimensional scaling (NMDS) and Indicator Species Analysis (ISA). Despite the broad overlap between epiphytic lichen communities of NPAs and PAs and a similar number of total and common species, PAs contain a significantly higher number of nationally rare and extremely rare species, including cyanolichens. These results are also confirmed by the indicator analysis. Although the Natura 2000 network does not explicitly address the conservation of lichens, the protected areas in our study can play a role in protecting the diversity of epiphytic lichens, especially nationally rare and endangered species. However, the future inclusion of red-listed epiphytic lichens among the target species of Annex II of the Habitats Directive would be welcome to better protect these organisms on a European level.
Circinaria nimisii (Megasporaceae, lichenized Ascomycota), a new manna lichen from Greece
Authors: Sohrabi Mohammad , Leavitt Steven D. , Obermayer Walter , Mayrhofer Helmut 
Published: September 2023

AbstractThe manna lichens, a group of vagrant species with subfruticose and subfoliose thalli in the genus Circinaria Link, have received attention for millennia. Here, a new manna lichen species, Circinaria nimisii sp. nov. (Megasporaceae), is described and illustrated. This vagrant lichen is found on Mount Olympus in Greece and is the fourth known manna lichen in Europe. The new taxon is characterized by its subfruticose, densely-branched thallus with a muddy, earthy colour, whitish pseudocyphellae on tips of branches, mature apothecia distinctly adnate to stipitate, and paraplectenchymatous cortex tissue. Molecular sequence data from the standard barcoding marker (nrITS) also corroborate the distinction of this species from closely related congeners. Finally, Agrestia zerovii, previously known only from its type locality in Ukraine, is proposed as a new synonym of Circinaria hispida.
Marchantiana pyramus, M. ramulicola and Austroplaca thisbe (Teloschistaceae, lichenized Ascomycota) – three new twig lichens from southern Patagonia
Authors: Søchting Ulrik , Sancho Leo G. , Arup Ulf 
Published: September 2023

AbstractThree twig-growing lichen species belonging to the family Teloschistaceae from southern Patagonia are described as new to science: Marchantiana pyramus sp. nov., with minute apothecia, orange due to dominant content of emodin, M. ramulicola sp. nov., with minute olive apothecia with dominant parietin and Austroplaca thisbe sp. nov., with clear yellow apothecia also with dominant parietin. Marchantiana subpyracea, M. epibrya and M. queenslandica are new combinations for species which, so far, are known only from New Zealand and Australia. Blastenia circumpolaris is shown to be very common in Patagonia and Marchantiana asserigena is documented for the first time from the Southern Hemisphere, viz. the Falkland Islands. The genus Marchantiana is analyzed here using three genes and is shown to be closely related to Yoshimuria; although appearing as paraphyletic, a monophyletic origin cannot be ruled out. Morphology, ecology and distribution support a monophyletic treatment and Marchantiana is therefore treated as such.
Arthonia epipolytropa and Arthonia subclemens, two new lichenicolous species on Lecanora polytropa, with a key to the microfungi known on this common species
Authors: Hafellner Josef , Grube Martin 
Published: September 2023

AbstractArthonia epipolytropa Hafellner & Grube and Arthonia subclemens Hafellner, Grube & Muggia are described as new to science. Both are specific parasites of Lecanora polytropa s. lat., but of differing pathogenicity and of very different appearance. Whereas the clearly parasitic Arthonia epipolytropa with its agglomerated ascomata is presently known with certainty from a number of localities along the arch of the Alps (Austria, Italy, Switzerland), other parts of Europe (Norway, Albania) and northern America (USA), the less harmful A. subclemens with its isolated sunken ascomata is currently known only from a small number of localities in the Eastern Alps (Austria, Italy) and various mountain ranges in southern Europe (Spain, North Macedonia, Greece). The species are compared with other Arthonia species known from Lecanora or one of its recently segregated genera. A key to the fungi regularly found on Lecanora polytropa s. lat. is presented.
Growth-dependent acclimation constrains climatic response for the lichen epiphyte Lobaria pulmonaria
Authors: Chinnery Emma V. , Ellis Christopher J. 
Published: September 2023

AbstractSpecies can respond to climate change by migrating to track their suitable climate space, and/or through adaptation (across generations) or acclimation (by individuals) to a changed in situ environment. Lichens provide an excellent model for studying acclimation; being poikilohydric, there is strong evidence that their phenotype presents an adaptation to different moisture regimes, and that key aspects of the phenotype, notably specific thallus mass (STM), have plasticity towards effective acclimation that maximizes water storage in drier environments. In this study we quantified acclimation of STM for Lobaria pulmonaria across a regional climatic gradient, and within sites for different microclimates, using a one-year common garden growth experiment. We found that STM tended to increase with thallus growth; however, when accounting for growth, STM shifted to be lower than average in wetter environments, higher than average in intermediate environments, and failed to respond in the driest environment where growth was compromised. The possibility of phenotypic acclimation in Lobaria pulmonaria appears to be functionally linked to the propensity for growth, and we present a scheme coupling growth with STM to define the limits of the species realized niche.

AbstractEnvironmental control strategies are commonly practised to limit biodeterioration issues threatening indoor cultural heritage objects, while they are still poorly exploited for the conservation of outdoor stone heritage surfaces, including rock art. In this study, we evaluated the environmental factors driving the diversity and abundance of lithobiontic communities in the Rock Engravings National Park of Naquane (UNESCO WHS n. 94, Italy). The survey considered 23 rocks that had been cleaned in the last three (3YC) or twelve (12YC) years or more than 40 years ago (NRC). A cyanobacteria-dominated biofilm and lichens (37 taxa) were the most widespread and abundant lithobiontic components, prevailing on 3YC–12YC and NRC rocks, respectively. On the latter, a turnover of xerophytic and meso-hygrophytic lichen communities was observed. On 3YC–12YC rocks lichen colonization, if present, was limited to nitrophytic species, including common epiphytes from surrounding trees and a small number of meso-hygrophytic species, with a prevalence of asexual reproductive strategies. Multivariate analyses including environmental parameters (canonical correspondence analyses) indicated that tree cover and the presence of bare or vegetated ground upstream of the rocks, probably prolonging wetness and providing nutrients by water transport, are the factors mostly related to the microbial and lichen recolonization of 3YC–12YC surfaces. On this basis, an experiment on preventive conservation was conducted, consisting of a new cleaning of a strongly recolonized 3YC surface combined with the building of a small wall to protect part of the rock from prolonged water fluxes. The fluorimetric and colorimetric monitoring of the rock surface, carried out 40 months after this new cleaning intervention, displayed recolonization on the unprotected area only, indicating the potential of preventive conservation strategies in outdoor environments.
A distinctive new species of Biatora (Ramalinaceae, Lecanorales) described from native European forests
Authors: Palice Zdeněk , Malíček Jiří , Vondrák Jan , Printzen Christian 
Published: September 2023

AbstractA unique crustose lichen species was recently documented from various types of preserved forests across boreal and temperate Europe (Norway, Ukraine, the Czech Republic) and the Caucasus (Russia). It is formally described here as the new species Biatora amylacea. A phylogeny based on ITS and mtSSU sequences demonstrates that it belongs to an isolated group within the core of Biatora s. lat., together with the recently described B. radicicola. It is a distinctive taxon within the genus on account of its amyloid exciple, otherwise known only from members of the Biatora rufidula group. The new species is also characterized by amyloid thalline hyphae and the production of soredia with a blue-green pigment. This microlichen may serve as a bioindicator species of old-growth forests.

Published: September 2023

AbstractThe species–area relationship (SAR) states that species richness increases with the increase of the sampled area, although other factors can influence the pattern. SARs have been tested on many different organisms, but only rarely on lichens. We aimed to test the SAR, across a wide range of area sizes, for three main substratum-related guilds of lichens, namely epiphytic, epilithic and epigaeic. The test was performed using data from lichen inventories carried out in 44 protected areas of various sizes across Italy. We found a positive correlation of species richness with area size for all three guilds, better fitted by the logarithmic function for epilithic lichens and by the power function for epiphytic and epigaeic lichens. Our results support the fundamental role of area size as the main driver for lichen diversity, suggesting that in an area-based conservation framework, larger protected areas are fundamental to support high lichen species richness. However, finer scale investigations are also required to better elucidate whether and how other environmental factors could interact with area size and modify SAR patterns. Exhaustive lichen inventories could be useful information sources to more robustly test such relationships, and therefore better inform conservation practices.
The Woman between Us: Sarah Nakimu Nalwanga and the Founding of Uganda’s Anglican Tradition
Authors: Teketwe Kimeze 
Published: September 2023

Abstract
There has always been a debate about the location and role of women during the persecution of Christians under Mwanga II’s first reign as Kabaka of Buganda. Kabaka is the Luganda equivalent of the English word king. The debate is partly fueled by a total absence of women from the pictures of Ugandans historically referred to as the Uganda Martyrs. This paper uses archival research to tell the story of an African woman who, in her adult life, married two devout Anglicans, in whose lives she was actively involved, laying a foundation for Uganda’s Anglican tradition. Evidence shows the first Anglican baptism, teacher and burial in Uganda are traced to her first marriage, which ended in early 1884 with the death of her husband from smallpox. Nakimu Nalwanga Sarah would have been the first martyr if not for the timely discovery that she was Mwanga’s relative. Still, as a punishment, she was ordered to witness the cruel burning of the first martyrs on January 31, 1885. She married again in a marriage that produced Uganda’s first catechist, deacon and priest. Her second husband was part of a team that completed the translation of the first Luganda Bible in 1895.

Was ist zu diesem Thema bereits bekannt? Recovery Colleges (RC) sind liberale, peer-gestützte Bildungseinrichtungen zur Förderung der individuellen, psychischen Gesundheitskompetenz und Zufriedenheit von Menschen mit beziehungsweise ohne seelischen Krisenerfahrungen. Wie wird eine neue Perspektive eingebracht? Abseits der Exploration von Recovery, Häufigkeiten von RCs in Deutschland und positivem Nutzen von Recovery Colleges, wird in diesem Beitrag der Fokus auf die zu wenig beschriebenen Prinzipien, Kernelemente sowie Strukturen von deutschsprachigen College-Einrichtungen im Zuge einer wahrlichen recovery-orientierten Praxis gerichtet. Was sind die Auswirkungen für die Praxis? Aufgrund der vorgestellten Prinzipien und Kernmerkmalen von RCs, kann für die Bildungseinrichtungen ein hoher Grad an recovery-orientierter Praxis festgestellt werden, welcher den Nutzenden von RCs und somit der psychosozialen Versorgungsstruktur in der Gemeinde zugutekommt.

AbstractLand cover controls the land‐atmosphere exchange of water and energy through the partitioning of solar energy into latent and sensible heat. Observations over all land cover types at the regional scale are required to study these turbulent flux dynamics over a landscape. Here, we aim to study how the control of daily and midday latent and sensible heat fluxes over different land cover types is distributed along three axes: energy availability, water availability and exchange efficiency. To this end, observations from 19 eddy covariance flux tower sites in the Netherlands, covering six different land cover types located within the same climatic zone, were used in a regression analysis to explain the observed dynamics and find the principle drivers. The resulting relative position of these sites along the three axes suggests that land cover partly explains the variance of daily and midday turbulent fluxes. We found that evaporation dynamics from grassland, peatland swamp and cropland sites could mostly be explained by energy availability. Forest evaporation can mainly be explained by water availability, urban evaporation by water availability and exchange efficiency, and open water evaporation can almost entirely be explained by exchange efficiency. We found that the sensible heat flux is less sensitive to land cover type. This demonstrates that the land‐atmosphere interface plays an active role in the shedding of sensible heat. Our results contribute to a better understanding of the dynamics of evaporation over different land cover types and may help to optimize, and potentially simplify, models to predict evaporation.
Interpretable Machine Learning Reveals Potential to Overcome Reactive Flood Adaptation in the Continental US

Published: September 2023

AbstractFloods cause average annual losses of more than US$30 billion in the US and are estimated to significantly increase due to global change. Flood resilience, which currently differs strongly between socio‐economic groups, needs to be substantially improved by proactive adaptive measures, such as timely purchase of flood insurance. Yet, knowledge about the state and uptake of private adaptation and its drivers is so far scarce and fragmented. Based on interpretable machine learning and large insurance and socio‐economic open data sets covering the whole continental US we reveal that flood insurance purchase is characterized by reactive behavior after severe flood events. However, we observe that the Community Rating System helps overcome this behavior by effectively fostering proactive insurance purchase, irrespective of socio‐economic backgrounds in the communities. Thus, we recommend developing additional targeted measures to help overcome existing inequalities, for example, by providing special incentives to the most vulnerable and exposed communities.
Effects of the Relative Dynamics of Ionospheric Irregularities and GPS Satellites on Receiver Tracking Loop Performance
Authors: Biswas Trisani , Paul Ashik 
Published: September 2023

AbstractTransionospheric satellite signals are exposed to perturbation, caused by irregularities generated in the ionosphere. However, the characteristics of the satellite motion can have an additional impact on signal perturbation, in addition to the effects of irregularity structures, that drift from west to east during geomagnetic quiet conditions. This paper reports the effect of Global Positioning System satellite geometry, on tracking loop performance of ground‐based receivers, during occurrence of ionospheric scintillations. Observations are made from station Calcutta (22.58°N, 88.38°E geographic; magnetic dip 34.54°), located near the northern crest of Equatorial Ionization Anomaly, during three different solar activity periods (March 2014, March 2015, and March 2022). Efforts have been made to study the correlation of east‐west component of satellite velocity at Ionospheric Pierce Point (IPP) with duration of loss‐of‐lock and rate of signal fading (<−10 dB), from ground scintillation pattern observations. Results of this study show 75%–78% correlation between duration of loss‐of‐lock and eastward component of satellite velocity, for all three period of observation. Subsequently, shorter duration of loss‐of‐lock has been observed corresponding to satellite velocity being westward. Signal fading rate is found to decrease with increasing satellite velocity, having median value of the fading rate cumulative distribution percentage, corresponding to satellite velocity of 16.69, 31.76, and 19.14 m/s respectively during March 2014, March 2015, and March 2022. Results of this study also indicate direction and component of satellite velocity at IPP to be a dominant cause of signal outage, even during periods of weak to moderate scintillations.
