Nutritional Benefits

Sitka spruce (Piceasitchensis (Bong.) Carr.) seedlings colonized by the ectomycorrhizal fungi Laccarialaccata (Scop. ex Fr.) Berk and Br., Hebelomacrustuliniforme (Bull, ex St. Amans) Quel., or Cenococcumgeophilum Fr. and a noninoculated control were planted on rotten wood, undisturbed duff, undisturbed duff on the north side of large stumps, and exposed mineral soil in an area recently clear-cut on Chichagof Island, southeast Alaska. Uptake and concentrations of N, P, K, Ca, Mg, and several micronutrients in foliage, stems, and roots were determined 2 years after outplanting. There were no significant interactions between fungal treatments and microsite types for uptake or concentration of any nutrient. Uptake and concentrations of N and P in foliage and roots did not differ significantly among fungal treatments. Foliar K and Cu concentrations were significantly higher in control seedlings than in those with L. laccata ectomycorrhizae. Calcium was the only nutrient analyzed that was present in higher concentrations in seedlings inoculated with H. crustuliniforme than in controls. Concentrations of foliar P, Mn, and Zn were significantly greater in seedlings grown on undisturbed duff (protected north side) than in seedlings grown on exposed mineral soil. However, foliar concentrations of all nutrients tested were not significantly different between seedlings grown on undisturbed duff (unprotected sites) and those grown on mineral soil. Seedlings grown on rotten wood had significantly greater concentrations of foliar Ca than seedlings grown on either exposed mineral soil or undisturbed duff. The on-site colonization of control seedlings after outplanting indicates that resident ectomycorrhizal fungi readily establish and appear to provide equal if not improved nutrient benefits compared to inoculated seedlings. Greater nutritional benefits were derived by planting on certain microsite types (duff and protected duff) than by inoculating with specific ectomycorrhizal fungi.

Holarctic Species

Anoplius tenuicornis (Tournier) is a holarctic species with a broad distribution both in Europe (Wolf 1967) and North America (Wasbauer and Kimsey 1985). Despite the widespread occurrence of the species, individuals are not frequently encountered, so it is not surprising that biological information on it has not been available for North America and very little for Europe. Richards and Hamm (1939) gave two fragmentary reports of some significance on A. tenuicornis in England, reported as A. piliventris (Morawitz). In one case, cocoons of the wasp were found in dead thistle stems. In the other, an old burrow of Ectemnius continuus (Fabricius) (Sphecidae) (reported as Solenius) in rotten wood contained a series of wasp cocoons and fragments of clubionid spiders, the presumed prey.

High Lead

Three microsites common to clear-cuts logged by the high-lead method in southeast Alaska were sampled to quantify the occurrence and viability of sclerotia of Cenococcumgeophilum Fr. Undisturbed duff had significantly greater numbers of sclerotia per gram or per cubic centimetre of soil than either exposed mineral soil or rotten wood. There were significantly fewer viable sclerotia per cubic centimetre of rotten wood than in either exposed mineral soil or undisturbed duff. Numbers of viable sclerotia that could contact the root plug of a containerized seedling when it was planted into rotten wood, exposed mineral soil, or undisturbed duff were calculated to be 0.7, 6.1, and 7.2, respectively. Expressing abundance of mycorrhizal propagules by soil volume, rather than weight, is more meaningful when microsites with large differences in soil bulk density are compared.

Interesting Alternative

Arabitol is a polyalcohol which has about 70% of the sweetness of sucrose and an energy density of 0.2 kcal/g. Similarly to xylitol, it can be used in the food and pharmaceutical industries as a natural sweetener, a texturing agent, a dental caries reducer, and a humectant. Biotechnological production of arabitol from sugars represents an interesting alternative to chemical production. The yeast Scheffersomyces shehatae strain 20BM-3 isolated from rotten wood was screened for its ability to produce arabitol from L-arabinose, glucose, and xylose. This isolate, cultured at 28°C and 150 rpm, secreted 4.03 ± 0.00 to 7.97 ± 0.67 g/l of arabitol from 17–30 g/l of L-arabinose assimilated from a medium containing 20–80 g/l of this pentose with yields of 0.24 ± 0.00 to 0.36 ± 0.02 g/g. An optimization study demonstrated that pH 4.0, 32°C, and a shaking frequency of 150 rpm were the optimum conditions for arabitol production by the investigated strain. Under these conditions, strain 20BM-3 produced 6.2 ± 0.17 g/l of arabitol from 17.5 g/l of arabinose after 4 days with a yield of 0.35 ± 0.01 g/g. This strain also produced arabitol from glucose, giving much lower yields, but did not produce it from xylose. The new strain can be successfully used for arabitol production from abundantly available sugars found in plant biomass.

Two strains isolated from rotten wood were included in the Saccharomyces group based on morphological characteristics. However, rRNA gene sequence analyses (including the 18S rRNA gene, 26S rRNA gene D1/D2 domain and internal transcribed spacer region) indicated that these two strains represent a novel species of Naumovozyma, for which the name Naumovozyma baii sp. nov. is proposed (type strain: BW 22T = CGMCC 2.04520T = CBS 12642T). The MycoBank number of the new species is MB800484.

On the warm morning of May 27, 1956 at the Trinity Valley field station near Lumby, B.C., some laundry hanging out to dry attracted large numbers of a strange Cerambycid-like beetle. Closer examination showed this insect to be Priacma serrata (Lec.) of the family Cupesidae (Fig. 1), an interesting and infrequently collected species.The family Cupesidae seems to have no economic importance, having only two genera and five species in North America that have been described (Blatchley, 1910). The larvae are reported to live in rotten wood; dissection of some adults collected at this time produced an entirely empty and deflated gut. The females and larvae of the closely related Micromalthus debilis Lec. are found in rotting wood in North America and were reported from decaying mine timbers far under ground in Johannesburg.

Collecting Techniques

The shining fungus beetles (Coleoptera: Staphylinidae: Scaphidiinae) comprise more than 1800 described species, which are usually small (≅0.84–14.30 mm long) (Tang et al. 2014 ; Löbl & Ogawa 2016) and found on bracket and resupinate fungi, mushrooms and slime molds (Newton 1984; Löbl & Leschen 2003; Löbl 2018). They are known to be diverse in forests of tropical and subtropical regions, which contrast to the low number of species currently known from Brazil: only 34 species and two subspecies from seven genera (Löbl 2018; von Groll & Lopes-Andrade, 2021). Any active search for Scaphidiinae in the Brazilian Atlantic forest reveals a considerable abundance and diverse of these organisms (pers. obs.), but they disperse rapidly if disturbed, and the success of field collections relies on the collectors’ skills, luck and collecting techniques and devices. The most common methods and devices for collecting shinning fungus beetles are sifting leaf litter, rotten wood and fungi, flight intercept (FIT) and V-flight intercept (V-FIT) traps, aspirators, sweeping, and hand collecting (Löbl & Leschen 2003; Tang et al. 2014; Löbl et al. 2021). Hand collecting is considered the best method, because the host fungi and larvae can be collected together to make associations (Löbl & Leschen 2003).
