Abstract

Background

To this day, merely 8% of all estimated fungi species are documented and, in certain regions, its biodiversity is practically unknown. Inside the Fungi Kingdom, macrofungi and lichens assume a critical part in the ecosystem functionality and have a historical connection to mankind's social, clinical and nutritious uses. Despite their importance, the diversity of these groups has been widely overlooked in the sub-Antarctic Region of Chile, a crucial area in the study of climate change due to its extraordinary biodiversity and its proximity to Antarctica. Few studies regarding both groups have been conducted in this sub-Antarctic Region and the data are still scarce and inaccessible, as these are only published in specialised journals, unreachable to local communities.

New information

This publication presents a records compilation available in previous published scientific and technical reports on macrofungi and lichen diversity. In total, 1263 occurrence records of 618 species (341 records of 251 macrofungi species and 922 records of 367 lichen species) were digitised and integrated into the regional platform Biodiversity Information System for Aysén (SIB-Aysén) and into GBIF. Here, we provide the fullest dataset on one of the most diverse group of living beings in one of the the least-known world regions.

Introduction

The biodiversity of the Fungi Kingdom is immense, including organisms with varied forms, colours and life habits, from macroscopic to microscopic sizes, being present in all ecosystems on Earth, both terrestrial and marine (Tedersoo et al. 2014). They are essential for ecosystem functionality (Öpik et al. 2006), due to their participation in the organic matter decomposition processes and the symbiotic relationships with other living beings (Dighton and White 2017). They also provide unique uses as food, medicinal or cultural with great potential for industrial development (Furci 2013, Hyde et al. 2019). Macrofungi and lichens are classified within this kingdom, in addition to yeasts and moulds. Macrofungi are non-photosynthetic heterotrophic free-living organisms with macroscopic fruiting bodies which may grow on various substrates (Dighton and White 2017). According to their nutrition, they can be classified as: saprophytes, which obtain nutrients and energy from decaying plant material; parasites, which derive nutrients from their host from other co-inhabitants; and symbiotics, which associate with other organisms with a mutual benefit to each other (Lazo 2001, Furci 2008). Lichens, on the other hand, are symbiotic organisms in which a fungi, known as mycobiont, is in a close symbiosis with microalgae or a cyanobacterium, known as photobiont (Hawksworth and Grube 2020). As photosynthetic organisms and pioneers of ecosystems (Vargas-Castillo and Morano 2014, Bjerke et al. 2003), macrofungi and lichens have essential ecological functions as they participate in the carbon and nitrogen cycles, act as primary colonisers in succession and serve as bioindicators (Furci 2013). They are found in all types of habitats and substrates, colonising rocks, logs, the ground and other organisms (Quilhot et al. 2012). Taxonomically, most lichens and macrofungi are classified in the Divisions Basidiomycota and Ascomycota, which differ in the way they produce and discharge spores (Lazo 2001).

It is estimated that there are between 2.2 to 3.8 million fungi species in the world, but even though methodological approaches are rapidly improving the available knowledge, less than 8% are currently known (Blackwell 2011, Hawksworth and Lücking 2017, Tedersoo et al. 2014). In Chile, one of the least known biodiversity groups is the Fungi Kingdom, with only 1500 known species (Furci 2008) and specifically, in the Aysén Region, the lack of knowledge is even greater. This Region, belonging to the sub-Antarctic zone of Chile together with the Magallanes Region, is one of the most pristine places on the planet, being crucial in the study of climate change due to its extraordinary biodiversity and its proximity to Antarctica (Osorio et al. 2002, Rozzi et al. 2020). This Region represents the biogeographic limits of the extreme Antarctic conditions (Macaya and Zuccarello 2010), making it an extremely fragile area, but with an extraordinary natural heritage since it houses a great variety of terrestrial and aquatic ecosystems (Álvarez et al. 2010). Due to the harsh conditions that occur in this territory composed of mountain ranges, deserts and glaciers, the fungi biodiversity is detrimentally affected, with only a few species being able to settle (Furci 2008). These hostile intrinsic conditions have even limited the fungi biodiversity research in this area in the past, but fortunately, there are increasing initiatives that contribute to the local fungi biodiversity knowledge directly from the government (Corporación Nacional Forestal 2009, Corporación Nacional Forestal 2010, Corporación Nacional Forestal 2012), as well as a regional platform that has been developed under the same standards as Darwin Core (DwC), the Biodiversity Information System for Aysén or SiB-Aysén (https://kataix.umag.cl/sib-aysen/). SiB-Aysén fosters citizen participation as it is an interactive platform that allows users to enter their records according to a validation protocol (Sánchez-Jardón et al. 2021).

One of the missions of this initiative involves the gathering of previous studies data, incorporating them into biodiversity information systems and making them accessible for consultation (Chavan and Penev 2011). This data integration effort is especially relevant in the remote areas of the planet, such as the sub-Antarctic Region of Chile, where sampling tasks are extraordinarily expensive and, therefore, more scarce. As long as the information remains disseminated in multiple sources, it is easier for the disparity to occur in subsequent sampling efforts (Kühl et al. 2020), causing over-representation of records in some areas, generally those closer to human populations (Barbosa et al. 2013). In any case, behind each GBIF dataset, there is considerable digitisation, compilation and validation efforts. Systematising the sampling or collection data is common, but adapting the databases to certain standards, such as Darwin Core, so that they are available to the public, represents an additional effort (Heberling et al. 2021).

The purpose of this work is to collect the macrofungi and lichen data available in other published scientific and technical reports to incorporate it in the Biodiversity Information System for Aysén (SIB-Aysén) and the GBIF. This way, the biodiversity information can be consulted and used in management and conservation programmes, as well as complemented by other scientific and citizen observations in future investigation and citizens science projects (Penev et al. 2017, Rozzi et al. 2020).

Project description

Title: 

Fungal literature records database of the sub-Antarctic Region of Aysén, Chile (https://kataix.umag.cl/sib-aysen/)

Personnel: 

Laura Sánchez-Jardón

Sampling methods

Study extent: 

The geographic extent (48°42'55"S to 44°8'3"S; 74°25'32"W to 71°32'18"W) of the digitised dataset corresponds to the Region of Aysén del General Carlos Ibáñez del Campo (XI Region) with an area 109.052 km2, representing about 14% of the Chilean territory. This Region is situated in the sub-Antarctic zone of Chile, which comprises both the Magallanes and Aysén administrative regions, both having an extraordinary biodiversity, representing one of the most pristine areas on the planet, unique for its proximity to Antarctica and with significant implications in the study of climate change (Osorio et al. 2002, Rozzi et al. 2020).

Sampling description: 

The digitisation aims to summarise the fungi species occurrences accumulated in previous mycological studies and published in reviewed scientific literature (Filippova et al. 2020). To fulfil the aim of this work, an exhaustive review of the scientific literature, related to the diversity of macrofungi and lichens in the Aysén Region, Chile, was carried out using scientific content search engines, such as Web of Science and Google Scholar. A total of 16 references were found (nine specialised journals, four books and three technical documents) that contained records or suggested the presence of macrofungi and lichen species within the territory of the Aysén Region (Bjerke et al. 2003, Lazo 2001, Osorio et al. 2002, Quilhot et al. 2002a, Quilhot et al. 2002b, Quilhot et al. 2002c, Furci 2008, Corporación Nacional Forestal 2009, Corporación Nacional Forestal 2010, Furci 2013, Corporación Nacional Forestal 2012, Quilhot et al. 2012,Ramírez et al. 2014,Sandoval-Leiva 2014, Vargas-Castillo and Morano 2014, Furci 2018). This data collection started with a project FIC from the Aysén Regional Government known as “Biodiversity Information System for Aysén, SIB-Aysén (BIP 40000522-0) and continued with the project “Hongusto: social innovation regarding wild and cultivated edible mushrooms from the Aysén region (CORFO 15IS-46635)”. Eventually, it will be complemented by the citizens’ observations associated with the SIB-Aysén. Eventually, the citizens’ observations associated with the SIB-Aysén will complement this study.

Quality control: 

The taxonomic nomenclature used has been updated according to MycoBank (available at https://www.mycobank.org/). The geographic coordinates have been systematised from what was reported by the authors in the publications; when only the locality was mentioned, it has been approximated using Google Earth; in both cases, the coordinates have been validated using the GBIF tool.

Step description: 

The records were systematised in a database with taxonomic, geographic and temporal information. The coordinates indicated by the authors were assumed; when not indicated in the publication, they were obtained from the locality names using GoogleEarth®. The substrate information of the lichens, in case that it was provided by the authors, was classified as follows according to the reviewed literature: epiphytes when only growing on trees or shrubs; epiphytic-lignicolous when growing on rotten wood or decaying organic matter; folicolous when growing on living tree leaves; muscicolous when growing on mosses; saxicolous when growing on rocks and terricolous when growing on the ground. The taxonomic nomenclature used in each publication was updated according to MycoBank. Ultimately, this information was systematised according to the DwC standard (Fig. 1) and uploaded to GBIF (Sánchez-Jardón et al. 2021). The complete dataset is available in Darwin Core Archive format via the Global Biodiversity Information Facility (GBIF).

Geographic coverage

Description: 

The records were distributed throughout the entire Aysén Region, with a slightly greater presence in the south-eastern half of the Region (Fig. 2). Broadly, the density of records is low (from 1 - 4 records per locality), although there are areas with a higher density (up to 178 records in the same locality). The locations with the highest numbers of records are Puntilla de los Cisnes, in the National Park Laguna de San Rafael (178 records), Tamago National Reserve (123 records) and Interpretation Center of the National Forest Corporation (CONAF) in Laguna de San Rafael too (76 records).

Traits coverage

Considering the type of substrate in which the lichen grow, most of the recorded lichen species are epiphytic (which includes epiphytic, lignicolous, folicolous and muscicolous of the database habitat categories) with 192 of 367 species with substrate information (Fig. 3), followed by 48 saxicolous species; 41 epiphytic-saxicolous species and 33 terricolous species. The remaining species were epiphytic-terricolous (28 species); saxicolous-terricolous (13 species) and epiphytic-saxicolous-terricolous (13 species). Regarding temporary coverage, the records cover a period of 51 years, from 1967 to 2018.
