Plant-soil feedbacks not only shape plant communities but also the abiotic and biotic nature of soils. These feedbacks are well-studied in natural and agricultural landscapes, but poorly studied in cities. Here, we investigated soil fungal communities, vegetation and soil abiotic properties in five urban green space types within urban Adelaide, South Australia. We surveyed eight, spatially-independent

Exploring the relationships between ecology and species traits in cyanolichens: A case study on Italy Fungal Ecol. (IF 2.656) Pub Date : 2020-05-24 Pier Luigi Nimis, Stefano Martellos, Alessandro Chiarucci, Silvia Ongaro, Marco Peplis, Elena Pittao, Juri Nascimbene
This work provides an overview of the ecology of all bipartite cyanolichens of Italy, exploring the relationships between ecological factors and species traits. A matrix of 205 species and several ecological descriptors was subjected to multivariate analyses (classification and ordination). Six groups of species with similar ecology were delimited, arranged along a gradient of decreasing aridity and

Growth rates and thallus loss in hair lichens along small-scale Picea abies-canopy gradients Fungal Ecol. (IF 2.656) Pub Date : 2020-05-20 Yngvar Gauslaa, Knut Asbjørn Solhaug, Nathan H. Phinney
We quantified annual growth rate and loss of Bryoria capillaris and Usnea dasopoga transplants on Picea abies on parts of lower branches in the inner versus outer canopy in small, medium and tall trees in hemiboreal forests. Light at branches in the inner canopy was 2.7 x (for Bryoria capillaris) and 2.0 x (for Usnea dasopoga) higher than the lichens’ respective light compensation points, 10.7 ± 1

Plant pathogenic fungi are harbored as endophytes in Rhododendron spp. native to the Eastern U.S.A. Fungal Ecol. (IF 2.656) Pub Date : 2020-05-20 Timothy L. Widmer, Michael B. McMahon, Douglas G. Luster
Invasive plant pathogens cause a substantial loss of yearly revenue and often lead to environmental change. The movement of plants is considered to be the main avenue for introduction of invasive plant pathogens. Government agencies attempt to reduce the risk of introductions by legislation and inspections. However, inspectors may not consider that plant pathogens can infect plants as endophytes that

Variation and plasticity in Epichloë alkaloid content of Festuca rubra across Europe Fungal Ecol. (IF 2.656) Pub Date : 2020-05-16 Beatriz R. Vázquez de Aldana, Päivi Leinonen, Iñigo Zabalgogeazcoa, Marjo Helander, Kari Saikkonen
Many symbiotic microbes can aid their host plant's defense against herbivores and pathogens either directly or indirectly through plant-mediated mechanisms. Thus, microbes are of interest to agricultural research. In this study, we used vertically transmitted Epichloë species because these fungal endophytes of grasses produce alkaloids that have been shown to protect the host from herbivory. Depending

Elevated air temperature shifts the interactions between plants and endophytic fungal entomopathogens in an agroecosystem Fungal Ecol. (IF 2.656) Pub Date : 2020-05-03 Li Sui, Hui Zhu, Wenjing Xu, Qinfeng Guo, Ling Wang, Zhengkun Zhang, Qiyun Li, Deli Wang
The possible effects of climate change on species interactions remain a very complex and challenging subject in community ecology. Here, we comparatively examine the interactions between maize (Zea mays) and an endophytic fungal entomopathogen (Beauveria bassiana) in a typical agroecosystem under both ambient and elevated air temperatures. We found that under ambient temperature certain key biological

The growth of Cryptococcus gattii MATα and MATa strains is affected by the chemical composition of their woody debris substrate Fungal Ecol. (IF 2.656) Pub Date : 2020-05-01 Jo-Marie Vreulink, Teun Boekhout, Hester Vismer, Alfred Botha
The dominance of MATα among cryptococcal strains has been ascribed to MATa strains being more sensitive to certain environmental factors; however no study has attempted to identify these factors. During the present study we determined whether the chemical composition of woody debris may influence the occurrence of Cryptococcus gattii MATa. We observed a positive correlation between the numbers of C

Diversity of foliar endophytes in a dioecious wild grass and their interaction with the systemic Epichloë Fungal Ecol. (IF 2.656) Pub Date : 2020-04-28 Patricia D. Mc Cargo, Leopoldo J. Iannone, Marcelo Soria, M. Victoria Novas
This study compares the culturable fungal endophytic community inhabiting leaves of Epichloë-infected (E+) and Epichloë-free (E-) plants of Poa bonariensis. Plants were collected from a wild population (dioecious species) where E+ and E- plants co-exist. Fungal endophytes were isolated and then morphology and ribosomal DNA internal transcribed spacer sequences were used for the identification of isolates
