Abstract:
The importance of old-growth forests for lichens: keystone structures, connectivity, ecological continuity In Switzerland, 621 lichen species are associated with forest habitats, of which 134 priority forest lichen species need special measures for their long-term conservation. Almost three-quarters of the forest species are considered old-tree dependent lichens because they depend on keystone structures, which are phenological traits of old trees. Threatened forest lichens (red list categories CR, EN and VU) require significantly larger stem diameters to establish compared to non-threatened species (LC and NT). Because of a limited dispersal capacity several lichen species also depend on a high ecological continuity, which characterizes them as oldgrowth forest lichens. The conservation of old-tree and oldgrowth forest dependent lichens in general and specifically the preservation of occurrences in managed forests by maintaining specific habitat trees is an urgent task for biodiversity conservation in forests. However, in order to ensure ecological continuity of keystone structures, future habitat trees must be fostered in close proximity to existing occurrences of rare and endangered lichen species.

Abstract:
Terrestrial lichens are an important part of the winter diet of forest-dwelling caribou ( Rangifer tarandus caribou (Gmelin, 1788)), and developing forest management guidelines to support high lichen biomass could enhance both individual- and population-level health of this threatened species. Our objective was to develop an index to assess terrestrial lichen biomass available to caribou at the landscape scale using ecoforest maps based on forest characteristics (age, density, and height) and geographical variables (slope, altitude, and latitude). We sampled 439 sites within 8340 km2 of the spruce–moss domain located >100 km north of the Saguenay River (Quebec, Canada). Since they are known to support terrestrial lichen, we sampled only spruce-dominated stands older than 50 years, representing 41.8% of the study area. Using a two-step approach, we first modeled lichen occurrence and thereafter lichen biomass in sites where lichens were found. Lichen occurrence was positively correlated with latitude but negatively with stand age, height, and density. Lichen biomass was primarily a function of altitude and tree density. Using this index could prioritize conservation of areas that are most likely to contain high lichen biomass, thus favoring caribou population maintenance in logged landscapes.

Abstract:
Sacred Natural Sites are relevant for biodiversity conservation, as in the case of forest sites that, across centuries, developed old growth structures and are now crucial for the conservation of epiphytic lichens and other specialized forest organisms. In this study, we investigated the epiphytic lichen flora of a small forest patch included in the Majella National Park (Abruzzo), whose old growth features and naturalness reflect its long lasting spiritual role that perfectly fits with the concept of Sacred Natural Site. Results revealed that the “Bosco di Sant’Antonio” hosts a rich and interesting epiphytic lichen flora, thus indicating the potential of this Sacred Natural Site for lichen conservation. Fifty-six species were found including two species newly recorded in Abruzzo, two red-listed species, and the sensitive species Lobariapulmonaria. This study corroborates the hypothesis that sacred forest sites are relevant for the conservation of specialized epiphytic lichens. In particular, in the Italian forest landscape where old-growth stands are practically absent, sacred forest sites may provide unique old-growth structures and buffer anthropogenic disturbance.

Abstract:
Abstract In dry habitats of European lowlands terricolous lichens and bryophytes are almost neglected in conservation practises, even if they may strongly contribute to biodiversity. This study aims at (a) testing the role of heathlands, acidic and calcareous dry grasslands for lichen and bryophyte diversity and conservation in lowland areas of northern Italy characterized by high human impact and habitat fragmentation; (b) detecting the effect of environmental drivers and vegetation dynamics on species richness and composition. Lichens, bryophytes, vascular plants, and environmental variables were recorded in 287 circular plots for 75 sites. Our results indicate that heathlands, acidic and calcareous dry grasslands host peculiar terricolous lichen and bryophyte communities that include several species of conservation concern. Thus, each habitat provides a complementary contribution to lichen and bryophyte diversity in continental lowland landscapes. Furthermore, in each habitat different factors drive species richness and composition with contrasting patterns between lichens and bryophytes. In terms of conservation, our results indicate that management of lowland dry habitats should act at both local and landscape scales. At local scale, vegetation dynamics should be controlled in order to avoid biodiversity loss due to vegetation dynamics and wood encroachment. At the landscape scale, patches of all the three habitats should be maintained to maximize regional diversity.

Abstract:
Alternatives to clear-cutting are being implemented to increase biodiversity of managed forests in the Pacific Northwest. Lichens are an integral component of old growth, but lichen biomass develops slowly in forests. We evaluated the long-term potential of live tree retention for lichen conservation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests. We sampled lichen litterfall in a 2-ha stand that contained 200- to 600-year-old remnant trees scattered in a forest composed mostly of 100-year-old trees that established following fire. We used association, principal components, and regression analyses to relate lichen litterfall biomass to the proximity of remnant trees. Two epiphytic lichens were strongly associated with remnant trees: the foliose cyanolichen Lobaria oregana (Tuck.) Müll. Arg. and the fruticose green algal lichen Sphaerophorus globosus (Hudson) Vainio. Biomass of both species was highest near remnant trees, and biomass was slightly higher within groves of remnant trees than it was at the edges of these groves or near isolated trees. Lichens appear to have persisted on remnant trees through the last fire and are slowly recolonizing younger trees from this source of propagules. Retention of live trees, maintenance of hardwoods, and longer rotation periods have great potential to maintain old-growth-associated lichens in at least some managed forests.

Abstract This study examines the occurrence of epigeic lichens on study plots located within different types of habitat near the Siemianowka retention reservoir in the Upper Narew Valley. The outcome of this research is a better understanding of epigeic lichens and the problems associated with their distribution and conservation. The investigation of the less common and hence more interesting taxa found within the study area was based on species composition analyses of lichens in different habitats, the degree of recognition in North Eastern Poland and their conservation status as well as threats within the country. A total of 48 lichen species, mainly from the genus of Cladonia, were identified, which is a typical number for these types of habitat. 19% of the species growing on soil are classified as threatened and some of them have been recorded only within this study area. In total, 15 lichen species are under the strict or partial protection.

Abstract:
In June 2000, at the joint meeting of the Canadian Botanical Association and the Canadian Society of Plant Physiologists, the author of this review was presented with the George Lawson Medal for lifelong contributions to botany and was invited to prepare a special contribution for the Canadian Journal of Botany. Subsequently, an invitation was received to give the Swinscow Lecture to the British Lichen Society and the Linnean Society in London. This commentary is a written version of that January 2001 lecture and presents a personalized view of developments in those areas of lichenology studied by the author during a career in Canada and other parts of the world. Aspects touched upon include lichen identification, spore dispersal, nutrient transfer between the symbionts, water relations, and lichen strategies in particular climatic regions. The value of lichens for monitoring pollutants is noted, and the developing problem of lichen conservation is discussed. Finally, a plea is made regarding the value of field teaching and field excursions with respect to recruiting the next generation of lichenologists.Key words: lichens, asci, carbohydrate transfer, ecophysiology, pollution, old-growth forests, lichen societies.

Abstract:
Lichens are used in traditional medicine, food and various other ethnic uses by cultures across the Himalayas and southwestern parts of China. Evidence-based knowledge from historical and modern literatures and investigation of ethnic uses from 1990 proved that lichen species used as medicine in the Himalayas and southwestern parts of China totaled to 142 species; furthermore, 42 species were utilized as food. Moreover, some lichens are popularly used for lichen produce in ethnic and modern life. An understanding and clarification of the use of lichens in the Himalayas and southeastern parts of China can therefore be important for understanding uses of lichens elsewhere and a reference for additional research of lichen uses in the future.

Abstract:
Soil-associated lichen species characteristic of north-eastern Patagonia are classified by cluster analysis into six groups using ecological and morphological characters. The constancy of species, the total number of species, the number of species per crust and the relative frequency of species are analysed at sites with different grazing levels: three non-grazed, three regulary grazed, and three heavily grazed. Using the results, the potential use of lichen groups as bioindicators of rangeland conservation and degradation are explored. Species of three lichen groups (group A: lichens growing on calcareous gravels; group C: terricolous lichens with pale, crustose non-areolate thalli; group F: terricolous lichens with pale, areolate thalli) are identified as sensitive to grazing, and most of the species forming these groups are suggested as potential bioindicators of grazing disturbance. Thus, Rinodina bischoffii, Caloplaca holocarpa, Catillaria lenticularis, Acarospora heppii (group A); Lecanora dispersa and Rinodina mucronatula (group C); and Psora decipiens (group F) are the species most sensitive to grazing disturbance. Conversely, species of group D (terricolous lichens with dark, foliose thallus: Collema coccophorum), and group B (lichens growing on siliceous gravels: Aspicilia contorta) may be indicated as the most resistant to grazing disturbance.

Abstract:
This study investigates the effects that lichens have on rock surfaces in which ancient rock art (petroglyphs and pictographs) may be found. The study area includes four sites in the United States: one quartzite site in southwest Minnesota, two sandstone sites in Wyoming, and one volcanic site in Central New Mexico. One additional granitic site studied is located northeast Queensland, Australia. The questions driving the pursuit of this dissertation research are: 1. How does the chemistry of the rock change with weathering and how deep is the profile? 2. Do lichens cause differential chemical changes? 3. How does the chemistry of the unaltered rock influence these changes? 4. Do lichens strip the patina or “desert varnish” from the rock surfaces? The results of this research confirm from elemental chemical analyses that geochemical changes do take place in the presence of lichens. The combined mechanical and chemical processes contribute to the degradation and greater erodability of all the rock surfaces studied. Chemically, we have demonstrated that cements that hold grains of rocks together can be dissoluble by lichen byproducts in the presence of an aqueous environment whether the rocks are sandstone or granite. This information regarding the mechanical and geochemical processes at work in natural environments has significant practical benefit for the management, conservation, and preservation of rock art sites everywhere.

Full text
Abstract:
The objective of the current study was to analyse the effect of landscape structure (habitat size and exposure to farmland) on the occurrence and abundance of Lobaria pulmonaria, a foliose cyanolichen. Since the agrarian revolution during the 19th century the agricultural landscape has become increasingly fragmented resulting in isolated meadows and wood-pastures surrounded by farmland. Lobaria pulmonaria is one of the species being affected by this habitat change, much due to their dispersal limitations, specific habitat demands and susceptibility to air pollution. 36 localities of two different size classes (< 1.5 ha and > 4.5 ha) and two different exposure classes (exposed or unexposed to farmland) were studied. The occurrence, size of lichen thallus and height of lichen patches on tree trunks were significantly positively affected by habitat size and negatively affected by habitat exposure. The implications of these findings for strategies to manage and conserve L. pulmonaria in a fragmented landscape are discussed.

Abstract:
Cette etude a ete proposee par l'institut national de recherches agronomiques et le laboratoire de recherche des monuments historiques dans le cadre d'un programme step europeen (step ct 90 - 0101). Ce travail essaie d'etablir les differents effets de la presence des etres vivants sur la degradation des monuments en granite. L'interface lichen-roche granitique est etudiee chez neuf especes de lichens saxicoles (caloplaca sp. , catillaria chalybeia, diploicia canescens, ochrolechia parella, pertusaria sp2. , tephromela atra, verrucaria tectorum, verrucaria sp. , lichen endolithique) par la methode micromorphologique sur lames minces. Une nouvelle methodologie a ete adaptee pour la preparation d'echantillons biologiques de la pierre, notamment par une coloration au calcofluor white m2r (colorant fluorochrome). Les resultats ont montre que les lichens exerces une alteration importante sur les mineraux de la roche. L'etude micromorphologique permet d'obtenir des valeurs moyennes de penetrations dans le substrat granitique jusqu'a 2 millimetres de profondeur. Des micro prelevements d'echantillons de roche non perturbes permettent a une autre echelle, en utilisant la microscopie electronique a transmission, d'observer la presence d'hyphes myceliens entre les paquets de feuillets de mica ou bien de constater la secretion d'acide organique sous la forme d'oxalate de calcium. Une cartographie de la colonisation biologique des facades externes de l'eglise de penmarc'h a ete menee et les surfaces presentant un recouvrement biologique ont ete calculees grace aux outils performants d'un systeme d'information geographique (arc-info). Il a de plus ete estime les surfaces presentant d'eventuelles alterations biologiques. La presence de bacteries dans des echantillons de granite est montree par des analyses microbiologiques quantitatives provenant de cinq monuments en bretagne. Un resultat interessant a la basilique du folgoet (finistere) revele une presence importante de bacteries nitrifiantes. Leur presence est egalement quantifiee avec la meme importance sur trois autres monuments en cotes-d'armor (la chapelle saint malo, l'eglise de meslin et la chapelle saint jacques le majeur). Leur developpement serait en relation avec l'existence d'une source d'ammoniac provenant des epandages de lisiers. Il ne semble pas en resulter de degradation specifique du granite

Abstract:
Este trabalho teve como objetivo determinar e avaliar as respostas físico-químicas, fisiológicas, bioquímicas e sensoriais associadas às técnicas de conservação pós-colheita de lichia, sendo que para isso foram realizados seis experimentos. No primeiro experimento, foi estudado o efeito da temperatura de armazenamento (0, 5, 10, 15 e 20ºC) em lichias Bengal por 15 dias. A taxa respiratória e a produção de etileno foram significativamente influenciadas pela temperatura de armazenamento, sendo que o aumento da temperatura ocasionou maiores perdas de sólidos solúveis totais (ºBrix), ácido ascórbico e aparência. Conclui-se que as temperaturas de 0ºC e 5ºC são as mais indicadas para a conservação de lichia durante 15 dias, nas condições do presente experimento. No segundo experimento, avaliaram-se embalagens de filme de policloreto de vinila (PVC) (12, 14 e 17 m de espessura); filmes plásticos de polietileno de baixa densidade (PEBD) de 10 e 20 m; filmes plásticos de polipropileno (PP) de 0,06 e 10 m; e embalagens de tereftalato de polietileno (PET), em lichias Bengal armazenadas a 5ºC e 90% UR por 15 dias. Os filmes PP de 0,06 e 10 µm, assim como os filmes PEBD de 10 e 20 µm, apresentaram reduções drásticas dos teores de O2 e aumentos significativos de CO2. Para as condições deste trabalho conclui-se que os filmes de policloreto de vinila (PVC) de 12, 14 e 17 µm e a embalagem de tereftalato de polietileno (PET) são os melhores filmes ou embalagens para o armazenamento de lichias a 5ºC durante 15 dias. No terceiro experimento foi estudado o efeito da aplicação de diferentes antioxidantes na conservação de lichias Bengal armazenadas a 5ºC e 90% UR por 15 dias. Verificou-se que o tratamento com ácido cítrico reduz a taxa respiratória de lichia durante o armazenamento a 5oC. Entretanto, nenhum dos antioxidantes testados foi eficiente para minimizar o escurecimento do pericarpo das lichias durante o armazenamento refrigerado. O quarto experimento avaliou o efeito da aplicação de diferentes concentrações de cloreto de cálcio (CaCl2) sobre lichias Bengal armazenadas a 5ºC e 90% UR por 15 dias. Conclui-se que o cloreto de cálcio reduz a taxa respiratória de lichias armazenadas a 5oC, mas não é eficiente para minimizar a perda da coloração vermelha do pericarpo destes frutos durante o armazenamento refrigerado. No quinto experimento foi estudado o efeito da aplicação de diferentes recobrimentos na qualidade de lichias Bengal armazenadas a 5ºC e 90% UR por 15 dias. Conclui-se que nenhum dos recobrimentos ou ceras testados minimizou a perda de qualidade de lichias armazenadas a 5ºC por 15 dias. O sexto experimento avaliou diferentes tempos e temperaturas de resfriamento rápido com água em lichias B3 por 10 dias. Nas condições deste experimento, conclui-se que o pré-resfriamento da lichia com água auxilia na minimização da perda de qualidade destes frutos, mas favorece o surgimento de altos índices de podridões.
The purpose of the present work was carried out with the objective to determine and to evaluate the physicochemical, physiological, biochemical and sensorial answers associated to the techniques of postharvest lychee conservation, and for that six experiments were evaluated. In the first experiment, the effect of the storage temperature (0, 5, 10, 15 and 20ºC) was evaluated in lychees \'Bengal\' for 15 days. The respiratory rate and ethylene production were influenced significantly by the storage temperature, and the increase of the storage temperature caused more losses of soluble solids (ºBrix), ascorbic acid and appearance. Temperatures of 0 and 5ºC are recommended for lychee conservation for 15 days, in the conditions of the present experiment. In a second experiment, packages of polyvinyl chloride (PVC) films (12, 14 and 17 m thickness) were evaluated; low density polyethylene (LDPE) films of 10 and 20 m; polypropylene (PP) plastics films of 0,06 and 10 m; and polyethylene terephthalate (PET) packages, in lychee \'Bengal\' stored at 5ºC and 90% RH during 15 days. The films PP 0,06 and 10 µm, as well as the films PEBD 10 and 20 µm, presented drastic reductions of the tenors of O2 and significant increases of CO2. For the conditions of this work it was concluded that the polyvinyl chloride (PVC) films of 12, 14 and 17 µm and the packing of polyethylene terephthalate (PET) are the best films or packages for the lychee \'Bengal\' storage at 5ºC for 15 days. The third experiment studied the effect of the application of different antioxidants in the conservation of lychees \'Bengal\' stored at 5ºC and 90% HR during 15 days. It was verified that the treatment with citric acid reduces the respiratory rate of lychee during the storage at 5ºC. However, none of the tested antioxidants was efficient to minimize the pericarp browning of the lychees during the cold stored. The fourth experiment evaluated the effect of the application of different concentrations of chloride of calcium (CaCl2) on lychees \'Bengal\' stored at 5ºC and 90% HR during 15 days. It was concluded that the chloride of calcium reduces the respiratory rate of lychees stored at 5ºC, but it is not efficient to minimize the red coloration pericarp loss of these fruits during the cold stored. In the fifth experiment it was studied the effect of the application of different coatings in the lychees \'Bengal\' quality stored at 5ºC and 90% HR during 15 days. It was concluded that none of the coatings or waxes tested minimized the of lychess quality loss stored at 5ºC during 15 days. The sixth experiment evaluated different times and temperatures of hydrocooling in lychees \'B3\' for 10 days. In the conditions of this experiment, it was concluded that the hydrocooling of the lychee aids in the minimization of the loss of fruit quality, but it favors the appearance of high indexes of rottenness.

Abstract:
AbstractThe world cultural heritage sites face new challenges for an effective protection and management because of destruction and damage initiated by both natural and anthropogenic causes. Fresh rock and sandstone surfaces of buildings are quickly colonized and covered by a layer of microorganisms, including phototrophs, lithotrophs, and heterotrophs to form a biofilm that alters the local conditions of the stone surfaces, especially under the favorable tropical climate conditions for autotrophic microorganisms and plants. Biofilms had been studied with indigenous or pure cultures of isolated microorganisms, but the selective ones that contribute to deterioration of the cultural heritage cannot be confirmed easily. Currently, high-throughput sequencing and metegenomics analyses are capable of obtaining microbial community and composition in great depth, but they also suffer from similar weakness unable to identify the culprits in the community. With these as background, this article presents a different approach by focusing on the biochemical processes and the responsible microorganisms involved to reveal the destruction processes for management and protection. Among these different functional groups of microorganisms, lichens are known as pioneering rock-decomposing microorganisms, and both sulfur-oxidizing bacteria and fungi participate in the decomposition of sandstone via sulfur cycling and initiation of salt attack of the stone afterward, resulting in defoliation and cracking of stone. Other microorganisms including ammonia-oxidizing bacteria and archaea, especially the latter, have been recently detected on sandstone monuments providing evidence on the new organisms involved in the deterioration of cultural heritage and buildings. In addition, fungi can colonize the surfaces of the matured biofilms and play a new role in the removal of them, which has a potential biotechnological application in conservation of cultural heritage. The new proposed approach by focusing the microorganisms with identified biochemical function is more productive than a description of the community composition and assembly when assessing cultural heritage biodeterioration, and this provides basic and useful information for effective protection strategies and management.

Abstract:
Our cultural heritage kept in sandstone is doubtless suffering from accelerated biodeterioration. Fungi play a key role, either by acid production, dye secretion or as microbiont in the symbiotic association of the lichen with algae. The use of the universal initiators for the amplification of conserved regions of the ribosomal genes has been serving as an excellent marker for the microorganism identification, due to the ubiquity and conservation of these regions present in the genome of the eucarionts. In this chapter, the different fungi species present in sandstone were identified using molecular analysis techniques, as amplifiers in genes chains and the sequentiation of the resultant fragments. A theoric model of the way that the fungus contributes to the biodeterioration of monuments is proposed, with the objective of a better understanding of the contributions of these microorganisms in the general process of biodeterioration.

Abstract:
In Latvia the forest legislation requires that at least five living trees must be retained per hectare after clear-cutting. It is known that retention trees significantly increase the biodiversity in production forest landscape. After clear-cutting retention trees function as habitats for various lichens, mosses, insects, fungi and birds. Over time retention trees are incorporated into the young forests stand and provide presence of old trees, which is necessary for many endangered and rare species. After the death, these trees turn into coarse woody debris which is an essential habitat and feeding source for many taxa. However, the conservation and mortality of the retention trees has not been studied extensively because this approach has been established recently. The aim of this study was to evaluate development of the retention trees in Hylocomiosa type of forests in Southern Latvia. In total 12 young forest stands were surveyed in 2009 and 2015. The total area – 13.7 ha, on average forest stand size varies from 0.5 to 3.0 ha. All the studied sites were harvested in 2002, 2004, 2006 and 2008. All measurements of tree species, height, and diameter and defoliation class assessed and the status of tree (growing tree, coarse woody debris – snags, stems and downed logs) was indicated. Results show that after the studied period of seven years 24 retention trees died. Average level of the tree mortality is 15 %. The mortality level of Scots pine retention trees is 5.8 %, for aspen – 50 % and that for birch – 92.3 %. An average it is 8.5 green retention trees per 1 ha of young stand (22.9 m3 ha-1). On average 2.3 pieces coarse woody debris are per 1 ha of young stand (3.52 m3 ha-1), mostly - aspen wood (2.4 m3 ha-1). Woody debris of the young stands is divided to the first 4 decay levels according to classification (Stokland et al., 2001). 50 % of the listed woody debris is related to the 3rd decay level which means that woody debris is moderately decomposed.
