“…Notably, fungi grow on oligotrophic environments (Sterflinger, 2000;Botha, 2011) wherein soluble K + may be at very low concentrations and highly effective K + uptake systems are needed (Bañuelos et al, 1995), and on plant debris (Harley, 1971), where excessive K + accumulation must be avoided (Benito et al, 2002). Frequently, the same species can grow equally well in either of the two conditions, which probably implies the use of different types of K + transporters and a tight coordination between them.…”

“…Wood-decaying fungi are excellent ecosystem engineers, because they directly modulate the availability of resources other than themselves for several other functional groups (Harley 1971;Jones et al 1994;Krajick 2001;Moore et al 2004). The fundamental ecological signiWcance of deadwood decomposition in forests has been highlighted in several reviews and conclusions for silviculture have been drawn repeatedly (Table 1).…”

Wood-decaying fungi in the forest: conservation needs and management options

Wood-decaying fungi are essential for the functioning of forest ecosystems. They provide habitat for many other organisms and enable the regeneration of forests throughout the world. Since wood decomposition is a decisive process in nutrient recycling, soil formation and the carbon budget of forest ecosystems, it is receiving increasing attention from forest ecologists, pathologists and managers. Research has focussed on the factors driving the speciesrichness of wood-decomposing organisms and is moving on to analyse the eVects of this species-richness on ecosystem functioning. Coarse woody debris (CWD) and its associated wood-decaying organisms have been drastically reduced in abundance and diversity by forestry and so these features often have potential as conservation indicators. Protective measures at a landscape level are needed for threatened wood-inhabiting fungi. These include restricting salvage operations in windthrow stands, actively encouraging the accumulation of deadwood in forests, and facilitating decay in standing trees by inoculating them with fungi. Here, we aim to collect and summarize recently produced work on deadwood ecology, pointing out research gaps and perspectives.

“…Most of the primary production, consisting primarily of mangrove leaves, becomes available to consumers following senescence and death. Decomposition of this detritus is one of the basic functions of ecosystems (Harley 1971). During an initial phase of a few days to weeks, up to 33% of total leaf mass may be lost due to leaching (Davis et al 2003).…”

Patterns of fungal colonization, mass loss and biochemical changes during the decomposition of predried and fresh (naturally fallen) leaves of Rhizophora mucronata were studied in a southwest mangrove of India. Dried and fresh leaves in litter bags were introduced at the mid-tide zone and retrieved after 1, 2, 4, 8, 10, 12 and 14 weeks. On incubation in the laboratory, a total of 5 ascomycetes and 18 anamorphic fungi were recorded. The majority of anamorphic taxa were natural inhabitants of the phyllosphere of senescent leaves. Following two weeks of exposure, they were largely replaced by marine fungi (ascomycetes and anamorphic fungi). More taxa were recovered from dried than from fresh leaves, and predrying accelerated the initial rate of mass loss. Ergosterol levels were much lower than those reported from vascular plant detritus exposed in other aquatic habitats. Both ergosterol and nitrogen levels peaked after between 4 weeks and 8 weeks of exposure; ergosterol levels subsequently declined, while nitrogen remained stable in predried leaves and fell in fresh leaves. The dynamics of remaining mass for the first 8 weeks of exposure were best described by a double-exponential decay model. The decay rate then appeared to accelerate, and the second phase was best described by a single exponential decay model. The apparent breakpoint coincided with an increase in the salinity of the mangrove swamp.
