“…The lower amount of plant litter on the soil surface may have resulted in lower soil moisture that slowed decomposition. Research supporting a more direct effect of fire on wood-decaying fungi was conducted in northern Europe [35] where the fungal flora associated with fallen Norway Spruce were sampled before and after an intense burn in Finland. Many species of fungi were lost due to the fire, especially from moderately to strongly decayed logs and from those most strongly burned.…”

Longleaf pine (Pinus palustris) ecosystems have been reduced dramatically throughout their range. Prescribed burning is considered the best way to restore and maintain plant communities associated with longleaf pine, but little is known about its effects on coarse woody debris and associated organisms. We conducted a 5-year study on the Osceola National Forest in northeastern Florida to determine how dormant-season prescribed burns at different frequencies (annual, biennial, quadrennial or unburned) applied over a 40-year period affected coarse woody debris volume, decomposition and nitrogen content, and subterranean termite (Reticulitermes spp.) activity. Burn frequency had no effect on standing dead tree or log volumes. However, freshly cut longleaf pine logs placed in the plots for four years lost significantly less mass in annually burned plots than in unburned plots. The annual exponential decay coefficient estimate from all logs was 0.14 yr −1 (SE = 0.01), with the estimated times for 50 and 95% loss being 5 and 21.4 years, respectively. Termite presence was unaffected by frequent burning, suggesting they were able to survive the fires underground or within wood, and that winter burning did not deplete their food resources.

“…Isso ocorre porque grande parte delas constrói ninhos em locais que as protegem do intenso calor. Além disso, sua organização social propicia o rápido restabelecimento em áreas queimadas (Kozlowski & Ahlgren 1974, Naves 1996 da abundância de besouros (Schlesinger et al 1997), inclusive com muitos desses organismos dependendo da ocorrência do fogo para aumentar seu tempo de sobrevivência (Granstrom & Schimmel 1993, Penttila & Kotiranta 1996. Essas espécies de insetos e outras, como alguns gafanhotos, são chamados pirófilos porque dependem de florestas recentemente queimadas ( Gillon 1983, Wikars 1992, Muona & Rutanen, 1994.…”

-The previous burning of sugarcane straw before harvest causes a series of inconvenients to the environment, specially to the tillage-associated insects. Fire is used to control pests and diseases in the agriculture, however its effect on insect populations is not well understood or documented, mainly on invertebrate groups responsible for nutrient recycling and energy flow. Our objective was to evaluate the effect of controlled burning sugarcane straw on the local insect community. The insects were collected in different dates before and after burning. The species selected for the analysis were affected by fire. Among the 35 taxa collected, 17 were considered more relevant to explain the observed variation in the frequency of species captured through time. In the first sampling after burning, there was a decrease in abundance of five species [Nitidulidae (species 2; Coleoptera), Lutosa brasiliensis (Brunner von Watternwyl) (Orthoptera: Gryllacrididae), Phoridae e Drosophilidae (Diptera) e Labia minor L. (Dermaptera: Labiidae)], among the 17 species selected for analysis. The canonical variate analysis for different sampling dates indicated significant difference between treatments, considering the composition and the species abundance. Despite the different composition of the insect community observed before and after burning, there is a tendency of community recovery to the observed pattern before burning.KEY WORDS: Labia minor, Xyleborus, Nitidulidae, soil trap RESUMO -A queima prévia ao corte dos canaviais causa uma série de inconvenientes ao meio ambiente e em particular à entomofauna associada à cultura. O fogo é largamente usado no controle de pragas e doenças na agricultura, entretanto seu efeito sobre populações de insetos não é bem entendido ou documentado, principalmente sobre grupos de invertebrados que são responsáveis pela ciclagem de nutrientes e fluxo de energia. Assim sendo, o objetivo deste trabalho foi avaliar o efeito da queima controlada da palhada da cana-de-açúcar sobre a comunidade de insetos locais. Os insetos foram coletados em diferentes datas antes e após a queima. Dos 35 taxa coletados, 17 foram considerados mais relevantes para explicar a variação observada da freqüência de captura das espécies ao longo do tempo. Na primeira coleta depois da queima, verificou-se a redução do número de insetos em cinco espécies [Nitidulidae (espécie 2; Coleoptera), Lutosa brasiliensis (Brunner von Watternwyl) (Orthoptera: Gryllacrididae), Phoridae e Drosophilidae (Diptera) e Labia minor L. (Dermaptera: Labiidae)], dentre as 17 selecionadas para análise. A análise de variáveis canônicas para as diferentes datas de coleta indicou diferenças significativas entre os tratamentos, considerando a composição e a abundância das espécies. Apesar da diferente composição da comunidade de insetos observados antes e após a queima, os dados apresentados sugerem uma tendência de recuperação da comunidade ao padrão observado antes da queima.

“…A relatively high proportion of the collections of this species have been made on charred wood, both in America and Europe (Bernicchia 2005;Kotiranta 1985;Niemelä 2005). In Finland, this otherwise rare species is sometimes common on old forest fire areas (Penttilä and Kotiranta 1996). However, the species is certainly not restricted to charred wood or burned forest.…”

Obba and Sebipora, new polypore genera related to Cinereomyces and Gelatoporia (Polyporales, Basidiomycota)

Cinereomyces clade is a newly proposed monophyletic group of polypores containing currently four genera and five species, including two promising biopulping fungi, Ceriporiopsis rivulosa and C. subvermispora. The Cinereomyces clade is well-delimited in nrDNA-based phylogenetic analysis, but its position in Polyporales remains unclear. Its closest relative may be found in the core polyporoid clade. Only a few morphological characters are common for all the species in the clade, e.g. CB-and CRB+ hyphae, white fruiting bodies, presence of oil, and middlesized spores. Culturally, the species are unified by producing simple-septate generative hyhpae in the margin, which produce simple-clamped hyphae backwards. The genus Gelatoporia is the correct place for Ceriporiopsis subvermispora. Two new genera are described in the group: Obba to incorporate C. rivulosa and a new austral species, Obba valdiviana, known from southern Argentina and recorded here also from Tasmania, and Sebipora to accommodate a new species from tropical Asia, S. aquosa. ITS sequences imply that Eurasian Gelatoporia subvermispora may belong to a different species from the North American one. G. subvermispora is recorded as new to Indonesia.
