Interactions between fungi and other microbes
No full textThough there are mutualistic relationships between fungi and organisms from other kingdoms, none have yet been described for fungi in nature. Fungi engage in a range of aggressive interspecific interactions, which can occur at a distance or following contact, due to parasitism or production of volatile and diffusible chemicals, including enzymes, toxins and other antifungal metabolites. Interactions between fungi and bacteria are many and varied, and these microorganisms affect each other’s growth, survival and virulence. These effects can be negative, positive or mutualistic. Intracellular viruses are widespread in fungi in all phyla. The host range of a virus type is very narrow, and frequency of infection within a species is variable, but sometimes high. Most viruses cause few or no obvious symptoms, but large beneficial and adverse effects have been reported. Fungi also interact with protists feeding on some and killing others which have ingested them
A climate of fear: stone cold psychopaths at work
No full textDemolishing the myth espoused by some psychologists that psychopathy and success somehow go together, this book mainly concentrates on psychopaths in the workplace. It tells the evidence based story of what it is like for people who work closely with a corporate psychopath. Those who have worked intimately with a corporate psychopath describe the experience as a living hell. It is a traumatic, career changing and life-changing event. The book gives case study details of psychopaths at work in organizations such as a UK charity, a marketing company and a health service provider, and discusses the terrible aftermath of their abusive, bullying presence and capricious leadership, on individuals, organizations and society.Corporate psychopaths are also associated with events of communal significance, with the book linking them to some of the biggest financial scandals of the last fifty years, including those at Enron, the Mirror Group and the Global Financial Crisis.The book also touches on political psychopaths, noting that from Magna Carta to the United Nations Universal Declaration of Human Rights, humanity has sought to keep a tight rein on the death-dealing destructiveness of psychopaths in political leadership. The book notes the likely destructive effects of a political psychopath leader having his finger on the nuclear button
Fungi, ecosystems, and global change
No full textAs decomposers, pathogens, and mutualistic symbionts with plants and animals, fungi play a major role in ecosystem processes including nutrient cycling, bioconversions, and energy flows. Fungi are globally distributed, but different species have distinctive geographical distributions that depend on hosts and climate. Fungal communities are being affected by global change, including climate change, land use change, pollution, pesticides and fertilisers, and movement of biota. Since decomposers, plant and animal pathogens, mycorrhizas and lichens are all affected, there are implications for disease and ecosystem processes. Loss of diversity is a problem at least as large for fungi as for plants and animals, but fungi are not usually a high profile group. Red Lists are being constructed for fungi using IUCN categories, though use of criteria for plants and animals is not always straightforward
Genetics - variation, sexuality, and evolution
No full textGenetics deals with variation and inheritance and forms the basis for understanding why fungi behave as they do. Genetic variations among fungi are considered at the level of the individual, populations, and species, but there are several difficulties in defining fungal individuals. The ability to distinguish self from non-self results from somatic incompatibility mechanisms. Populations comprise assemblages of individuals of a species. The species is the fundamental unit of biological classification, but there are different ways of defining a species, including biological, morphological and phylogenetic, and practical difficulties in delimiting them. Some of the life cycles and sexual processes within the fungi promote outcrossing and others restrict it. Variations between and within species and populations are brought about by microevolution, mutation, selection, gene flow, genetic drift, recombination, transposable elements, horizontal gene transfer, and epigenetics

Interactions between basidiomycota and invertebrates
No full textBasidiomycota are, in most terrestrial habitats, the primary agents of organic matter decomposition. They play a key role in associated ecosystem processes. Inevitably they interact frequently with invertebrates, and these interactions are highly dynamic. They may be direct or indirect, and prove beneficial or detrimental to either or both partners. In this chapter the variety of interactions is explored and the impact of basidiomycetes as a food and habitat resource, and as a predator is assessed. The consequence of fungal-invertebrate interactions on fungal community structure and faunal behaviour is also considered, as are the implications of these effects on nutrient cycling and ecosystem processes such as decomposition and productivity. The sensitivity of the interacting organisms to changes in climate, and general environmental change, with consequential effects on ecosystem activity, is also discussed
