“…We consider spore inoculation is the most realistic option for local nurseries that probably cannot afford the cost of mycelium production or purchase. Nonetheless, EcM taxa other than those proposed here have been reported from nurseries and naturally established Nothofagaceae seedlings as Descolea (Palfner et al, 2008;Valenzuela Flores et al, 2008;Álvarez et al, 2009;Fernández et al, 2015;Salgado Salomón et al, 2018a), Hebeloma (Fernández et al, 2015;Salgado Salomón et al, 2018a), Sebacina, Inocybe, Laccaria, Genea (Fernández et al, 2015;Marín et al, 2018), Tomentella (Kuhar et al, 2016;Fernández et al, 2013Fernández et al, , 2015Salgado Salomón et al, 2017, 2018a, Clavulinaceae (Fernández et al, 2015), Thelephorales (Fernández et al, 2015), Pyrenomataceae (Fernández et al, 2013;Salgado Salomón et al, 2018a). To broaden the perspective of EcM species best suited to inoculate nursery plants, especially for those with low fruiting frecuency, small spores production or corticioid habit, mycelium inoculum production, mycorrhizal infection and field performance tests will be required.…”

The southernmost portion of the Andes in South America hosts Nothofagaceae forests that form ectomycorrhizal (EcM) associations. We compiled all the published reports of EcM taxa from these woodlands, based on fruit-body collections and molecularly identified root tips. This resulted in 87 peer-reviewed research papers dealing with EcM associations from Nothofagaceae forests published over the past 62 years. Based on these papers the EcM richness and its association with Nothofagaceae species was analyzed. Represented by 45 genera (34 Basidiomycetes and 11 Ascomycetes), 479 EcM taxa have been recorded, plus an additional 46 EcM taxa which are potentially EcM. Cortinarius was the most frequent and diverse genus, with 64.9% of total species. Nothofagus dombeyi had the highest number of unique EcM species, followed by N. pumilio, N. antarctica and Lophozonia obliqua. The EcM community associated with Nothofagus species, except N. nitida, showed higher similarities among themselves, than with Lophozonia and Fuscospora species. Beta diversity indexes showed EcM Nothofagus species have 29–42% niche overlap, while Nothofagus—Lophozonia only had 1–16%. The assessment of the accuracy of the EcM diversity, host specificity and community structure deserve further studies combining phylogenetic analysis based on broad ecological surveys. On the basis of pre-selected criteria Austropaxillus statuum, Cortinarius fragilis, Cortinarius xiphidipus and Hallingea purpurea are proposed as candidates for nursery spore inoculations, and should be subject to scientific evaluation to determine costs and benefits.

“…Potential conflict between conifer and Nothofagus species for new habitat is therefore a key conservation concern because there is a high likelihood that conifers will dominate (Dickie et al, 2022; Peltzer, 2018; Standish et al, 2008). Conifer invasions have profound effects on ecosystems, altering community composition, reducing species diversity and changing ecosystem processes such as nutrient cycling (Dickie et al, 2022; Nuñez et al, 2017; Salomón et al, 2018). In fact, legacy effects on soil communities often mean that even after removal of conifer infestations, recovery of native species is limited and reinvasion by conifers or other invasive plants is more likely (Dickie et al, 2022; Peltzer, 2018).…”

AimThe impact of climate change on forest biodiversity and ecosystem services will be partly determined by the relative fortunes of invasive and native forest trees under future conditions. Aotearoa New Zealand has high conservation value native forests and one of the world's worst invasive tree problems. We assess the relative effects of habitat redistribution on native Nothofagus and invasive conifer (Pinaceae) species in New Zealand as a case study on the compounding impacts of climate change and tree invasions.LocationAotearoa New Zealand.MethodsWe use species distribution models (SDMs) to predict the current and future distribution of habitat for five native Nothofagus species and 13 invasive conifer species under two 2070 climate scenarios. We calculate habitat loss/gain for all species and examine overlap between the invasive and native species now and in future.ResultsMost species will lose habitat overall. The native species saw large changes in the distribution of habitat with extensive losses in North Island and gains mostly in South Island. Concerningly, we found that most new habitat for Nothofagus was also suitable for at least one invasive species. However, there were refugia for the native species in the wetter parts of the climate space.Main ConclusionIf the predicted changes in habitat distribution translate to shifts in forest distribution, it would cause widespread ecological disruption. We discuss how acclimation, adaptation and biotic interactions may prevent/delay some changes. But we also highlight that the poor establishment capacity of Nothofagus, and the contrasting ability of the conifers to invade, will present persistent conservation challenges in areas of both new habitat and forest retreat. Pinaceae are problematic invaders globally, and our results highlight that control of invasions and active native forest restoration will likely be key to managing forest biodiversity under future climates.
