“…Legacy effects of historical forest and current forest on soil microbial community structure Historical logging may alter the richness (Kataja-aho et al 2011;Souza et al 2012) and biomass (Mazzei et al 2010) of plant communities, which may in turn modify the composition of soil microbial communities (Bardgett and Wardle 2010). Our results indicate that there is a substantial link between soil microbial PLFA composition and the composition of the current forest.…”

Background and Aims Gaining a better understanding of the legacy effects of logging and forest restoration on soil microbial communities could improve our ability to conserve biodiversity and promote ecosystem sustainability. Herein, we investigated how soil microbial community is linked to natural, restored, and planted forests and the legacies of historical forest. Methods Soil microbial biomass and composition were measured in four forest types (i.e., primary forest, onceclearcut forest, twice-logged forest, and plantation forest) and related to physico-chemical soil properties and forest community structure data by using analysis of covariance. Results Fungal, bacterial, and total microbial biomass measured by phospholipid fatty acid profiles were significantly lower in the two secondary forests and the plantation than in the primary forest. The conversion of vegetation and soil regimes due to forest logging altered microbial communities. Conclusions Our findings elucidate the correlation of plant communities and soil characteristics to soil microbial communities in the context of subtropical forest management. Naturally restored and planted forests may affect soil microorganisms largely by directly modifying the soil labile C and N fractions of organic matter.

“…Estos autores también destacan la importancia de estos organismos para la incorporación de biomasa que favorece la f iltración vertical del agua y evita la escorrentía superf icial y lateral. Finalmente, la cantidad y forma espacial de los poros del suelo facilitará el desarrollo de las raíces de las plantas; y los exudados radiculares cementarán los agregados y evitarán la movilidad de las partículas edáf icas (Glasbey et al, 1991;Kataja-aho et al, 2011). Fracciones texturales.…”

La Reserva Ecológica del Pedregal de San Ángel de Ciudad Universitaria (REPSA-CU) alberga una fracción del derrame original de lava del volcán Xitle y actualmente el suelo y la comunidad vegetal son afectados por la fragmentación del paisaje, el depósito de residuos de relleno (como cascajo y otros materiales) y las construcciones irregulares. Se realizó una descripción de las principales propiedades físicas del suelo en sitios con topografía contrastante (planos abiertos conservados y perturbados, grietas y hondonadas). Se encontró un efecto signif icativo de la topografía sobre las propiedades edáf icas. La materia orgánica mostró correlaciones positivas con la porosidad, la arcilla y la humedad; y mostró correlaciones negativas con la densidad aparente y real, la compactación, la acidez y el contenido de arena. El porcentaje de materia orgánica fue el atributo más importante para la clasif icación y el ordenamiento canónico de los sitios. Los planos abiertos perturbados siguieron una trayectoria edafogénica diferente de los sitios conservados y asemejan Urbanosoles. Se sugiere la implementación de estrategias encaminadas a lograr su restauración ecológica. La clasif icación del suelo de esta reserva corresponde a tres órdenes probables: 1) Entisol háplico, por la edad geológica de su deposición y los procesos de pedogénesis en curso; 2) Litosol volcánico, por la recurrencia de afloramientos rocosos lávicos de origen magmático y 3) Andosol vítrico por la naturaleza de su material parental y predominancia de arenas. Se concluye que el suelo de la REPSA-CU es incipiente y actualmente los horizontes de diagnóstico están en proceso de desarrollo. La importancia ambiental de su suelo radica en su capacidad de f iltración y retención de agua; su porosidad y compactación le permiten ser un banco de semillas y hábitat de diversas especies de insectos. La fragilidad de los agregados edáf icos y la predominancia textural de arena representaron un factor latente de erosión.

“…Kataja-aho et al (2011) observed that especially the extent of exposed mineral soil patches differ between the stump removal and conventionally prepared clear-fellings. As changes in nutrient transformation processes are impending just in the disturbed soil, we took soil samples from mineral soil exposed in the stump removal practice and compared those with samples taken from mineral soil in the conventionally site prepared areas.…”

We studied in central Finland whether stump harvesting after clear felling of coniferous forest poses further short-term changes in soil carbon and nitrogen dynamics when compared to the traditional site preparation method, mounding. Exposed mineral soil patches in Norway spruce (Picea abies) dominated clear-cut stands were sampled 1â5 years after the treatments. The extent of the exposed mineral soil surface was significantly larger at the stump removal sites when compared to the mounding sites. No differences were found in soil pH, organic matter content or total concentration of soil C between the treatments or treatment years. Total concentration of soil N was consistently higher and C:N ratio lower in the stump removal plots than in the mounded plots. Further, both net N mineralisation and nitrification were clearly increased in the stump removal plots one year after the treatments. Soil microbial activity (CO production) was higher in the stump removal plots but similar difference was not found in sieved soil samples incubated in the laboratory. Fluxes of other important greenhouse gases (CH and NO) did not seem to be affected by stump removal. The differences between the stump removal and mounding procedures were most obviously attributed to more substantial soil disturbance by stump pulling and/or differences in the microbial communities and quality of soil organic matter in the differently treated soil.242
