Abstract:
AbstractSpores of the dung fungus Sporormiella have been suggested to indicate the presence, perhaps also the abundance of past megaherbivore populations. Nonetheless, basic studies demonstrating a correlation between Sporormiella concentration in lacustrine sediments and modern herbivore abundance are lacking. This study of Sporormiella representation in grazed and ungrazed landscapes provides supporting evidence for the application of Sporormiella as an indicator of megaherbivore presence and abundance in ancient landscapes. However, Sporormiella representation is spatially sensitive to the distance from the dung source. In lakes where Sporomiella are abundant in shoreline sediments, they decline sharply with increasing distance from the lake edge. Although this study provides supporting evidence for the application of Sporormiella as a proxy for herbivore presence and abundance, independent proxies should be applied in conjunction with Sporormiella to control for changes in lake size.

Abstract:
AbstractSpores of the dung fungus Sporormiella become abundant following the historic introduction of grazing herbivores at seven sites in the western United States. During the Holocene they are generally rare, but at six sites Sporormiella spores are abundant before the extinction of Pleistocene megaherbivores ca. 11,000 yr B.P. Sporormiella spores are directly linked to extinct megaherbivores by their presence in mammoth dung preserved in Bechan Cave, Southern Utah. Their abundance in late-glacial sediments may reflect the abundance of megaherbivores during Quaternary, thereby indicating the age of Pleistocene extinctions where other indicators are absent.

Abstract:
AbstractOne major challenge in the study of late-Quaternary extinctions (LQEs) is providing better estimates of past megafauna abundance. To show how megaherbivore population size varied before and after the last extinctions in interior Alaska, we use both a database of radiocarbon-dated bone remains (spanning 25–0 ka) and spores of the obligate dung fungus, Sporormiella, recovered from radiocarbon-dated lake-sediment cores (spanning 17–0 ka). Bone fossils show that the last stage of LQEs in the region occurred at about 13 ka ago, but the number of megaherbivore bones remains high into the Holocene. Sporormiella abundance also remains high into the Holocene and does not decrease with major vegetation changes recorded by arboreal pollen percentages. At two sites, the interpretation of Sporormiella was enhanced by additional dung fungal spore types (e.g., Sordaria). In contrast to many sites where the last stage of LQEs is marked by a sharp decline in Sporormiella abundance, in interior Alaska our results indicate the continuance of megaherbivore abundance, albeit with a major taxonomic turnover (including Mammuthus and Equus extinction) from predominantly grazing to browsing dietary guilds. This new and robust evidence implies that regional LQEs were not systematically associated with crashes of overall megaherbivore abundance.

Abstract:
This study aimed to identify and characterize the pathogens associated with symptoms similar to Phaeosphaeria leaf spot (PLS) of maize in different environmental conditions in Brazil. During the last decade, PLS became an important disease of maize in Brazil. However, doubt persists about the causal agent. Maize leaves with PLS-like lesions were collected from two locations (Cristalina, Goiás State [GO] and Vila Maria, Rio Grande do Sul State [RS]) in two growing seasons. Fungi associated with leaf lesions were isolated and cultured for taxonomic identification. Pathogenicity tests were carried out and the results indicated that three fungi (a Phyllosticta sp., Phoma sorghina, and a Sporormiella sp.) caused leaf spot similar to PLS on maize. The composition of pathogenic fungi in PLS-like lesions varied depending on locations and growing seasons. The fungi P. sorghina and a Phoma sp. (Plenodomus section) occurred in all environments, but the Sporormiella and Phyllosticta spp. were restricted to GO and RS, respectively. The results support the hypothesis that various pathogens are involved in PLS-like symptoms of maize and environmental conditions may influence the predominance of a specific agent.

Abstract:
AbstractWhether humans or climate change caused the extinction of megafaunal populations is actively debated. Caves in the Lagoa Santa provide mixed assemblages of megafauna and human remains; however, it remains uncertain the extent to which humans and megafauna interacted or overlapped temporally. Here we present the first paleoecological record from lowland South America that tracks the decline of megafauna and its ecological implications. We provide a data set for pollen, charcoal, and Sporormiella, from two lakes in southeastern Brazil that span the last 23,000 yr. The data showed reduced abundances of Sporormiella and an inferred megafaunal population decline that began 18,000 yr ago, with the functional extinction occurring between 12,000 and 11,500 yr ago. Population declines coincided with wet events. The age of the final megafaunal decline is within the range of the first human occupation of the region. Our data are consistent with climate causing the population collapse, with humans preventing population recovery and inducing extinction. We did not observe some of the ecological repercussions documented at other sites and attributed to the megafaunal extinction. Habitat-specific ecological consequences of the extinction add to the heterogeneity of late Pleistocene and early Holocene landscapes.

Abstract:
AbstractKnowledge about vegetation dynamics during the last glacial and deglacial periods in southeastern North America is under-constrained owing to low site density and problematic chronologies. New pollen records from two classic sites, Anderson Pond, TN, and Jackson Pond, KY, supported by AMS 14C age models, span 25.2–13.7 ka and 31.0–15.4 ka, respectively. A transition from Pinus dominance to Picea dominance is recorded at Jackson Pond ca. 26.2 ka, ~ coincident with Heinrich Event H2. Anderson and Jackson Ponds record a transition from conifer to deciduous-tree dominance ~ 15.9 and 15.4 ka, respectively, marking the development of no-analog vegetation characterized by moderate to high abundances of Picea, Quercus, Carya, Ulmus, Fraxinus, Ostrya/Carpinus, Cyperaceae, and Poaceae, and preceding by ~ 2000 yr the advent of similar no-analog vegetation in glaciated terrain to the north. No-analog vegetation developed as a time-transgressive, south-to-north pattern, mediated by climatic warming. Sporormiella abundances are consistently low throughout the Jackson and Anderson Pond records, suggesting that megafaunal abundances and effects on vegetation varied regionally or possibly that the Sporormiella signal was not well-expressed at these sites. Additional records with well-constrained chronologies are necessary to assess patterns and mechanisms of vegetation dynamics during the last glacial and deglacial periods.

Abstract:
As a result of mycological research 34 species of coprophilous ascomycetes from 14 genera, 10 families, and 5 orders were recorded on the territory of the Oleshkivski Pisky National Nature Park. Among them 15 species belonged to the class Sordariomycetes, 12 – to Dothideomycetes, and 7 – to Pezizomycetes. Among the orders of the fungi, Sordariales – 12 species, Pleosporales – 11, and Pezizales – 7, occupy the leading position; the rest of the orders revealed the fewer number of species. Among the families, Sporormiaceae, Podosporaceae, Coniochaetaceae, Delitschiaceae, and Sordariacea, were the most abundant regarding the number of species and specimens. The species from the five leading families represent 64,7% of the total number of identified species. Among the found genera of the coprophilous ascomycetes, Coniochaeta, Delitschia, Sordaria, Sporormiella, and Triangularia prevailed by number of species, demonstrating much larger diversity, than others. Environmental conditions inside the park are more favorable for the development of loculoascomycetes and pyrenomycetes. The discomycetes species diversity was much less. The list of recorded fungi and their substrates is presented. All species of ascomycetes were collected on the hare and cattle excrements. Other dung types have not been studied. 31 species are new to the territory of the park, 15 species are new records for the steppe zone of Ukraine. Coniochaeta hansenii and Sporormiella tetramera are first recorded in Ukraine. Descriptions, illustrations, synonyms and general distribution are provided for them. C. hansenii is a fairly common and widespread species in the world, occurring mainly on the leporid droppings. In the park, this species was also collected on hare dung. S. tetramera also belongs to the widespread but rare species of coprophilous ascomycetes, known from isolated records in a few countries. It was collected on the hare excrements in the park. Сoniochaeta leucoplaca, Delitshia perpusilla and Triangularia comata were collected for the first time in the steppe zone of Ukraine and for the second time in the country.

AbstractA total of 389 strains of fungi belonging to 38 species were isolated from 10 lichen species of the Western Ghats, southern India. All the lichens screened, irrespective of their growth forms or location, harboured endolichenic fungi. Most of the fungi belonged to the Ascomycotina. Chaetomium sp. 1, Hypoxylon investiens, Nemania bipapillata, Nodulisporium sp., Paecilomyces sp., and Sporormiella intermedia were the most common ones and were present in 5 or more lichen species. Of the 28 sporulating fungi, 7 belonged to Xylariales, and their total colonization frequency in all the lichens was also high. This observation further substantiates the high ecological amplitude of Xylariales, possibly due to overlapping ecological niches and their ability to inhibit co-occurring endolichenic fungi.

Abstract:
Endophytic fungi were isolated from leaves of Rhizophora apiculata Bl. and Rhizophora mucronata Lamk., two typical mangrove plants growing in the Pichavaram mangrove of Tamil Nadu, Southern India. Three hundred leaf segments from each plant species were sampled during dry and rainy months. More endophytes could be isolated during the rainy months than during the dry period. Hyphomycetes and sterile forms were more prevalent than ascomycetes or coelomycetes. Sporormiella minima, Acremonium sp. strain MG1 and a sterile fungus (MG90) were isolated from both plants irrespective of the season. Some endophytes were common to both plants, although a few appeared to be host specific. This is the first report on fungal endophytes in leaves of mangrove plants in India.Key words: endophytic fungi, Rhizophora apiculata, Rhizophora mucronata, mangrove, leaves.

Abstract:
AbstractNon-pollen palynomorphs and elemental geochemistry data from Lake Kifuruka in western Uganda provide evidence of environmental change in the tropical African region since the beginning of the Holocene. The multi-proxy record presented here shows that dry conditions dominated the end of the Pleistocene evidenced by calcium enriched sediments and suppressed fungal taxa activity. Moist conditions dominated the early Holocene and persisted until just after 1960 cal yr BP. Elevated frequencies of individual fungal spore taxa associated with herbivory and soil erosion, including Sordaria-type, Sporormiella-type, Chaetomium-type, and Glomus-type, about 4300 cal yr BP suggests a significant environmental change that could be linked to human activities. A convergence of multiple proxy data, including microscopic charcoal, elemental geochemistry, and fungal spores, strongly support the occurrence of anthropogenic forest disturbance in the Albertine Rift about 4300 cal yr BP.

Abstract:
Forty-nine taxa of sporulating microfungi were isolated in pure culture from the bark and wood of living and recently cut stems of trembling aspen (Populus tremuloides) from several sites in central Alberta and northeastern British Columbia. Stems were either healthy, blue stained, or decayed, or else possessed cankers or black galls. Several ecological groupings of fungi were recognized, including wood-staining fungi (e.g., Ophiostoma piliferum), black-gall-associated fungi (e.g., Hyphozyma lignicola, Knufia cryptophialidica,Phoma etheridgei), canker-causing pathogens (e.g., Nectria cinnabarina, Tympanis spermatiospora, Valsa sordida), and fungi that could be referred to as endophytes. This latter group consisted of an assortment of fungi normally found in niches other than wood (e.g., Ciborinia whetzelii, Sporormiella similis), microfungi associated with decayed wood (e.g., Cryptosphaeria lignyota, Phialocephala fusca, Phialophora alba, Phialophora bubakii, or canker-causing fungi isolated from healthy tissue (e.g., Hypoxylon mammatum, Leucostoma nivea.Key words: microfungi, endophytes, Populus, aspen, wood, Ascomycota, hyphomycetes, coelomycetes.

Abstract:
AbstractPollen analysis and five radiocarbon dates of a 687-cm core provide a detailed chronology of environmental change in a marsh at the head of Newport Bay, Orange County, California. Sediment deposition kept pace with sea-level rise during the early history of the marsh. From ca. 7000 to 4500 yr B.P. the site was a freshwater marsh, trees were more abundant than today, and grassland was the regional vegetation. As sea level rose, salt marsh gradually invaded the site. Brief periods of freshwater marsh 3800, 2800, 2300, and after 560 yr B.P. correlate with episodes of global cooling during the Neoglacial. The historic period is marked by the appearance of exotic species (particularly Erodium cf. cicutarium and Eucalyptus) and the spores of fungi (Sporormiella and Thecaphora). Peak influx of pollen, spores, and charcoal probably reflect greater frequency of flooding and erosion ca. 5000 yr B.P. and during the last 1000 yr.

Abstract:
The Central American Dry Corridor (CADC) is the most densely populated area of the Central American Isthmus and is subject to the greatest variability in precipitation between seasons. The vegetation of this region is composed of Dry Tropical Forests (DTF), which are suggested to be highly susceptible to variations in climate and anthropogenic development. This study examines the vulnerability of past DTF surrounding the Asese peninsula, Nicaragua to climatic and anthropogenic disturbances over the past c. 1200 years. Past vegetation, climate, burning, and animal abundance were reconstructed using proxy analysis of fossil pollen, diatoms, macroscopic charcoal, and Sporormiella. Results from this research suggest that DTF have been highly resilient to past climatic and anthropogenic perturbations. Changes in DTF structure and composition appear to be linked to the abundance and intensity of fire. Pre-Columbian anthropogenic impacts on DTF are not detected in the record; however, DTF taxa decline slightly after European contact (1522 C.E.). Overall the DTF for the Nicaraguan region of the CADC were found to be highly resilient to both climatic and anthropogenic disturbances, suggesting that this region will continue to be resilient in the face of future population expansion and climatic variation.

Abstract:
Several potent inhibitors of squalence synthetase have been discovered. Zaragozic acid A is produced by several fungi; zaragozic acid B is produced by several strains of Sporormiella intermedia; zaragozic acids C, E, and F are produced by Leptodontidium elatius; zaragozic acids D and D2 are produced by Amauroascus niger. L-731,120 and L-731,128 are minor components and coproduced with zaragozic acids A and B, respectively. Viridiofungins A, B, and C are produced by Trichoderma viride. Viridiofungin A is also produced by an unidentified sterile fungus. Several of the zaragozic acids are also potent inhibitors of farnesyl-protein transferase (FPTase). Inhibitors of FPTase may act as potential anticancer drugs. Chaetomellic acids A and B are produced by a fungus, Chaetomella acutiseta, while fusidienol is produced by Fusidium griseum. All three compounds are potent inhibitors of FPTase. Our experiences suggest that many novel inhibitors of both squalene synthase and FPTase are produced within a diverse phylogenetic array of filamentous fungi. Several of the zaragozic acids are potent inhibitors of both FPTase and squalene synthases. This is consistent with our observations that zaragozic acids and chaetomellic acids share some structural similarity. Key words: natural inhibitors, squalene synthase, farnesyl-protein transferase.

Abstract:
AbstractSamples taken from sedimentary archives indicate that fungal non-pollen palynomorphs (NPPs) can be used to provide information on forest cover, fire regime, and depositional environment in the eastern Andean flank montane forest of Ecuador. Within the 52 samples examined, 54 fungal NPP morphotypes are reported, of which 25 were found to be previously undescribed. Examination of fungal NPPs over a gradient of forest cover (2–64%) revealed three distinct assemblages: (1) low (<8%) forest cover Neurospora, IBB-16, HdV-201, OU-102, and OU-110 indicative of an open degraded landscape; (2) medium (8–32%) forest cover Cercophora-type 1, Xylariaceae, Rosellinia-type, Kretzschmaria deusta, Amphirosellinia, Sporormiella, and Glomus suggestive of a forested landscape disturbed by herbivores and soil erosion; and (3) high (32–63%) forest cover Anthostomella fuegiana, OU-5, OU-101, OU-108, and OU-120. Environmental variables for forest cover (forest pollen), available moisture (aquatic remains), regional fire regime (microcharcoal), and sediment composition (organic carbon) were found to explain ~40% of the variance in the fungal NPP data set. Fire was found to be the primary control on fungal NPP assemblage composition, with available moisture and sediment composition the next most important factors.
