“…In addition, both lichens and their phycobionts perform essential functions in terrestrial ecosystems, but because they are often not well known in different types of habitats, they are underrepresented in conservation assessments and implementation when compared to other groups of organisms, such as vascular plants or animals 52 . These results could be incorporated into frameworks to protect the extraordinary biodiversity hosted by Miocene gypsum outcrops in the Iberian Peninsula.…”

This study analyses the interactions among crustose and lichenicolous lichens growing on gypsum biocrusts. The selected community was composed of Acarospora nodulosa , Acarospora placodiiformis , Diploschistes diacapsis , Rhizocarpon malenconianum and Diplotomma rivas-martinezii . These species represent an optimal system for investigating the strategies used to share phycobionts because Acarospora spp . are parasites of D. diacapsis during their first growth stages, while in mature stages, they can develop independently. R. malenconianum is an obligate lichenicolous lichen on D. diacapsis , and D. rivas-martinezii occurs physically close to D. diacapsis . Microalgal diversity was studied by Sanger sequencing and 454-pyrosequencing of the nrITS region, and the microalgae were characterized ultrastructurally. Mycobionts were studied by performing phylogenetic analyses. Mineralogical and macro- and micro-element patterns were analysed to evaluate their influence on the microalgal pool available in the substrate. The intrathalline coexistence of various microalgal lineages was confirmed in all mycobionts. D. diacapsis was confirmed as an algal donor, and the associated lichenicolous lichens acquired their phycobionts in two ways: maintenance of the hosts’ microalgae and algal switching. Fe and Sr were the most abundant microelements in the substrates but no significant relationship was found with the microalgal diversity. The range of associated phycobionts are influenced by thallus morphology.

“…The list clearly needs to be updated, based on much lichenological work in Alaska since the list was created. No federally listed lichens are present in Alaska, but we presume this reflects the difficulties of the federal listing process for lichens and our lack of information rather than the occurrence of rare lichens (Allen et al 2019).…”

We inventoried lichens in Kenai Fjords National Park in Alaska, USA We assembled the known information on occurrence and ecology of lichens in this park by combining field, herbarium, and literature studies. Our results provide baseline data on lichen occurrence that may be used in resource condition assessments, vulnerability assessments, long-term ecological monitoring, and resource management. We report a total of 616 taxa of lichenized fungi from the Park, plus an additional five subspecies and three varieties, all of which are new additions to the National Park Service database for this park unit. An additional five species of nonlichenized lichenicolous fungi are reported here. Eight non-lichenized fungi that are traditionally treated with lichens are also included, most of these associated with bark of particular host species. Four taxa new to North America are reported here (Arctomia delicatula var. acutior, Aspicilia dudinensis, Myriospora myochroa, and Ochrolechia bahusiensis), along with 44 species new to Alaska. Numerous species have been confirmed using ITS barcoding sequences. Also several records assigned to the genus level are reported, many of those are likely new species.

“…Por otra parte, encontramos que un 46% de las especies registradas en este estudio en el Parque Rucamanque de la Comuna de Temuco son endémicas del sur de Sudamérica (Tabla 1) y que están asociadas principalmente al bosque nativo (Galloway 1989(Galloway , 1992(Galloway , 1994White & James 1988), por lo que es necesario avanzar en describir la biota de estos remanentes de Bosque nativo, para poder estimar su valor de conservación. Cabe destacar que los líquenes endémicos, debido a su distribución más restringida, son más vulnerables frente a la pérdida de área climáticamente adecuada aumentando su vulnerabilidad a la extinción como ha sido mostrado en estudios realizados en EEUU y Canadá (Allen & Lendemer 2016, Allen et al 2019. La riqueza de especies de líquenes es dependiente de la especie arbórea, con variaciones entre los distintos forófitos, siendo Nothofagus obliqua el que presenta mayor número de especies de líquenes seguida por N. dombeyi y Persea lingue (11 y 5, respectivamente).…”

INTRODUCCIÓNLos líquenes son organismos complejos producto de la asociación simbiótica, entre un hongo (micobionte) y un organismo fotosintético (fotobionte), que bien puede ser, un alga verde o una cianobacteria, o ambos (Nash 2008). Los líquenes corticícolas son diversos y funcionalmente importantes en los ecosistemas forestales, donde contribuyen a la biomasa y juegan un papel clave en el ciclo del agua y los nutrientes (Van Stan & Pypker 2015;Asplund & Wardle 2016). La diversidad de líquenes corticícolas está relacionada con el tipo de bosque, la edad, la composición y la estructura, así como con la disponibilidad de luz y humedad entre otros factores (
