“…From a practical standpoint, the threshold temperatures for bacteria and fungi are usually reached to a depth of 2 inches (5 cm) or more in the mineral soil during medium-or high-severity fires (Theodorou and Bowen 1982, Shea 1993, Giardina and others 2000. As a result, decreases in microbial populations due to the direct effect of soil heating are common immediately following either wildfire (Acea and Carballas 1996, Hernandez and others 1997, Prietro-Fernandez and others 1998 or some higher severity prescribed burns (Ahlgren andAhlgren 1965, Pietikainen and. Indirect long-term change in soil temperature can also result from modifications to vegetation cover and microclimate following fire.…”

“…Response of Soil Microorganisms to Fire-Fire affects most organisms that inhabit the belowground environment in both direct and indirect ways (Ahlgren andAhlgren 1965, Borchers andPerry 1990). Fire impacts soil organisms directly by killing or injuring the organisms, and indirectly by its effect on plant succession, soil organic matter transformations, and microclimate.…”

“…It also modifies the habitat of microorganisms by destroying organic matter, altering soil temperature and moisture regimes, and changing the postfire vegetation community and rates of organic matter accumulation. Consequently, changes in microbial population size and activity are common following wildfire and prescribed fire (see Ahlgren 1974, Raison 1979, Borchers and Perry 1990, Neary and others 1999 for reviews). Most reviews are quick to point out, however, that microbial responses are variable, or even unpredictable, depending on site conditions, fire intensity and severity, and sampling protocol.…”

“…As an example, rapid declines in soil microbial populations due to fire are usually transitory. Population sizes often match or surpass preburn levels within a growing season (Ahlgren andAhlgren 1965, Renbuss andothers 1973). Successful recolonization following fire is a function of several factors, including incomplete mortality of native populations, spore germination, influx of wind-blown organisms, and microbial growth stimulations from available nutrients.…”

_____________________________________ Neary, Daniel G.; Ryan, Kevin C.; DeBano, Leonard F., eds. 2005. (revised 2008This state-of-knowledge review about the effects of fire on soils and water can assist land and fire managers with information on the physical, chemical, and biological effects of fire needed to successfully conduct ecosystem management, and effectively inform others about the role and impacts of wildland fire. Chapter topics include the soil resource, soil physical properties and fire, soil chemistry effects, soil biology responses, the hydrologic cycle and water resources, water quality, aquatic biology, fire effects on wetland and riparian systems, fire effects models, and watershed rehabilitation.

“…Entretanto, seu efeito sobre populações de insetos e outros invertebrados não é bem entendido ou documentado (AHLGREN 1974, ANDERSEN 1991. Suas implicações na dinâmica populacional de formigas têm sido escassamente investigadas, mas a influência desses insetos sobre as mudanças nos ecossistemas e na composição da vegetação são bem estabelecidas (RISSING 1986, HÖLLDOBLER & WILSON 1990.…”

Impacto da queima da palhada da cana-de-açúcar no ritmo diário de forrageamento de Atta bisphaerica Forel (Hymenoptera, Formicidae)

Este trabalho foi conduzido de julho de 2001 a junho de 2002 em uma plantação de cana-de-açúcar em Oratórios, Minas Gerais, Brasil, objetivando investigar o impacto de uma queima controlada de baixa intensidade (235,26 kcal.s-1.m-1) da palhada seca de cana-de-açúcar sobre a atividade forrageadora de A. bisphaerica. Durante todo o período do estudo, uma correlação negativa entre o fluxo de operárias transportadoras de carga vegetal para o ninho com temperatura e com umidade relativa do ar foi observada. Meses com menores quantidades de dias com chuvas apresentaram maior fluxo de operárias transportadoras de cargas. A atividade forrageadora foi reiniciada somente 15 dias depois da queima da palhada, com padrão de forrageamento similar ao observado em colônia localizada em área não queimada. Entretanto, por dia, estimou-se que 518,0 g e 670,0 g de folhas frescas de vegetal não entraram para o interior dos ninhos durante esses 15 dias. Isso, de alguma maneira, deve ter comprometido o desenvolvimento dessas colônias.

Climate change impacts drive warmer winters, reduced snowfall, and forest fires. In 2020, a wildfire scorched about 1508 hectares of black pine (Pinus nigra Arnold) forests in Türkiye. Whether the combined effects of lack of snow and forest fires significantly alter winter soil respiration (Rs) and soil temperature remains poorly understood. A field experiment was conducted in the postfire and undisturbed black pine forests during the winter to quantify Rs rates as affected by lack of snow and forest fire. We applied four treatments: snow‐exclusion postfire (SEPF), snow postfire (SPF), snow‐exclusion‐undisturbed forest (SEUF), and snow undisturbed forest (SUF). The SEPF exhibited the significantly lowest mean Rs rates (0.71 μmol m−2 s−1) compared to the SPF (1.02 μmol m−2 s−1), SEUF (1.44 μmol m−2 s−1), and SUF (1.48 μmol m−2 s−1). The Rs also showed significant variations with time (p < .0001). However, treatments and time revealed no statistically significant interaction effects (p = .6801). Total winter Rs (January–March) ranged from 4.47 to 4.59 Mt CO2 ha−1 in the undisturbed forest and 2.20 to 3.16 Mt CO2 ha−2 in the postfire site. The Rs showed a significantly positive relationship (p < .0001) with the soil (0.59) and air (0.46) temperatures and a significantly negative relationship (p = .0017) with the soil moisture (−0.20) at the 5 cm depth. In contrast, the Rs indicated a negative but not statistically significant relationship (p = .0932) with the soil moisture (−0.16) at the 10 cm soil depth. The combined effects of lack of snow and forest fire significantly decreased Rs, thus conserving the soil's organic carbon stocks and reducing the CO2 contribution to the atmosphere. In contrast, a warmer winter significantly increased Rs rates in the undisturbed forest, suggesting an acceleration of soil organic carbon losses and providing positive feedback to climate change.
