“…Past forestry practices in unmined forest have increased the proportion of jarrah to marri (Abbott and Loneragan 1986) and, more recently, these two species have experienced decline and die-off caused by disease, drought and extreme heat (Paap et al 2008;Matusick et al 2013). The value of revegetation as feeding habitat for black cockatoos will need to be balanced against potentially competing land uses in the jarrah forest.…”

Context: Provision of key habitat resources is essential for effectively managing species that have specific ecological requirements and occur in production landscapes. Threatened black cockatoos in the jarrah (Eucalyptus marginata) forest of Western Australia have a wide range, so their conservation requires support from all land tenures, not just reserves. Mining in the jarrah forest temporarily removes cockatoo feeding habitat, so it is important to understand how cockatoos exploit revegetated areas for food resources. Aims:We aimed to determine whether there were successional patterns in cockatoo feeding activity in revegetation aged from 4 to 23 years at three mine sites in the jarrah forest in south-western Australia. Methods:We surveyed 232 plots in revegetation to document (1) structural and floristic variation in vegetation across mine sites and revegetation ages, (2) differences in cockatoo feeding activity across mine sites and revegetation ages on the basis of feeding residues and (3) any edge effect reflecting preferential use of vegetation at the interior or exterior of mine pits. We also documented the frequency of occurrence of cockatoo food plants and feeding residues in 480 plots in unmined forest to compare with revegetated areas.Key results: Marri (Corymbia calophylla) and jarrah were commonly consumed in unmined forest and Banksia and Hakea species were also fed on to a lesser extent. Revegetated mine pits provided food within 4 years and continued to do so up until the oldest plots studied (23 years). The relative importance of food plants shifted from proteaceous species in young revegetation to myrtaceous species in intermediate to older revegetation. However, extent of feeding on myrtaceous species in older revegetation did not equate to feeding rates in unmined forest, with lower frequencies recorded in revegetation.Conclusions: Black cockatoos fed in revegetation at all three mine sites, despite variations in vegetation age, structure and floristics. Feeding on proteaceous and myrtaceous food plants occurred within 4 and 7 years of revegetation being established, respectively, indicating that some food resources are restored quickly after mining disturbance of the jarrah forest. Implications:Our results emphasise the importance of monitoring fauna recolonisation over appropriate time scales, to understand how successional processes in revegetation influence fauna population persistence in production landscapes.

“…The genus Quambalaria is well known in Australia, particularly due to the damage that Q. pitereka and Q. coyrecup cause on species of Corymbia (Simpson 2000;Paap et al 2008;Pegg et al 2008). These fungi are confined to the eucalypts, most of which are native to Australia, and it is intriguing that Q. eucalypti has not been found in Australia until very recently.…”

Abstract. Quambalaria eucalypti, a serious pathogen of Eucalyptus, is believed to be native to Australia and introduced into various southern hemisphere countries, including Uruguay. In this study we record the discovery of Q. eucalypti causing leaf lesions on Myrceugenia glaucescens, a tree native to Uruguay. The identity of the pathogen was confirmed using DNA sequence comparisons of the internal transcribed spacer (ITS) region of the rDNA operon, as well as morphological characteristics. This is the first record of the pathogen on a host other than Eucalyptus. It clearly indicates a disturbing example of an alien invasive pathogen having undergone a host-shift from non-native Eucalyptus to a native tree in Uruguay.

“…The genus Quambalaria was erected by Simpson (2000) to accommodate three species, Q. pitereka, Q. eucalypti and Q. pusilla, commonly recognized as eucalypt pathogens. Recently, Q. cyanescens (de Beer et al, 2006) and Q. coyrecup (Paap et al, 2008) have been also been described as plant pathogens. The genus Sympodiomycopsis was proposed by Sugiyama et al (1991) and, at the time of writing, includes three described species: S. paphiopedili (Sugiyama et al, 1991), S. kandeliae (Wei et al, 2011) and S. yantaiensis (Chen et al, 2013).…”

During a survey of yeasts vectored by migratory birds in the Mediterranean basin, isolations from the cloacae of members of the order Passeriformes collected in Ustica (Italy) were performed. Based on phylogenetic analysis of the D1/D2 domain of the 26S rRNA gene and the internal transcribed spacer ITS1-5.8S rRNA gene-ITS2 region, five yeast isolates clustered in a new lineage within the Microstromatales clade. The DNA sequences of these isolates differed from those of their closest relatives, Jaminaea angkorensis and Jaminaea lanaiensis, by 20 and 25 nt substitutions in the D1/D2 domain and 119 and 131 nt substitutions in the complete ITS region, respectively. In addition, the five isolates showed phenotypic characteristics not observed in their closest relatives, such as the ability to grow at 44 8C and at pH 2.5, which suggests a possible adaptation to the bird gastrointestinal tract. On the basis of the isolation source, phenotypic features and molecular strain typing carried out with randomly amplified polymorphic DNA (RAPD)-PCR and mini-satellite-primed (MSP)-PCR analysis, the five isolates were characterized as five distinct strains of a novel species formally described as Jaminaea phylloscopi sp. nov., with 551B6T (5PYCC 6783 T 5CBS 14087 T ) as the type strain. The Mycobank accession number is MB811984.The Microstromatales represent an order that contains several teleomorphic and anamorphic genera. Among them, the genera Quambalaria and Sympodiomycopsis include the largest number of species, with five and three taxa, respectively, whereas the genus Jaminaea, the latest to be described (Sipiczki & Kajdacsi, 2009) (1991) and, at the time of writing, includes three described species: S. paphiopedili (Sugiyama et al., 1991), S. kandeliae (Wei et al., 2011) and S. yantaiensis (Chen et al., 2013). The genus Jaminaea comprises J. angkorensis (Sipiczki & Kajdacsi, 2009) and J. lanaiensis (Wei et al., 2011). This last species was originally described as Sympodiomycopsis lanaiensis by Mahdi et al. (2008).Recent studies have been focused on the diversity and ecology of ascomycetous yeasts carried by migratory birds (Cafarchia et al., 2006a; Cafarchia et al., 2006b;Francesca et al., 2010Francesca et al., , 2012 During an investigation of fungal diversity associated with cloacae of migratory birds in Ustica, several species of filamentous fungi were isolated and characterized (Alfonzo et al., 2013). Among them, five phenotypically similar isolates were preliminarily classified as basidiomycetous yeasts and stored for further investigation. In the present study, we show that these isolates represent five distinct strains of a novel species of the order Microstromatales.Birds were sampled during the migration from subSaharan areas to Europe in Ustica (388 429 N 138 109 480 E; sample date: 2-4 May 2009) (Alfonzo et al., 2013), an island north of Sicily (Italy) that represents one of the most important stop-over sites in the Mediterranean basin . Animals were captured, ringed and identified following the procedures re...
