“…After three days in the Berlese funnels, all soil remaining was manually examined under a 3× magnifying scope to collect any remaining individuals. Most groups of soil invertebrates were identified to the order level, except for better known groups, such as Coleoptera, when identifications of families was possible using available keys [46][47][48][49][50][51][52][53][54][55] .…”

The global expansion of tree plantations is often claimed to have positive effects for mitigating global warming, preventing soil erosion, and reducing biodiversity loss. However, questions remain unanswered about the impacts of plantations on belowground diversity and soil properties. Here, we examine how forestry plantations of exotic trees affect critical soil functions and the composition of invertebrate assemblages, by comparing invertebrate diversity and soil physico-chemical properties between non-native Pinus radiata plantations, and nearby native forests in a region of extensive plantation activity in south-central Chile. We quantified differences in diversity, abundance, and community composition of soil invertebrates, as well as fundamental soil properties such as soil water content, water infiltration, nutrient status, and pH. We show that in this landscape mosaic of native forest and plantations, both soil invertebrate communities and physical soil properties differed significantly between systems, despite similar soil origins and topographies. We found a significant loss of soil carbon and a major reduction in taxonomic and functional diversity of soil invertebrates in pine plantation sites. Soil biotic and abiotic characteristics of plantations differed significantly from native forests in plantation-dominated south-central Chile, with profound consequences for ecosystem processes and resilience to future climate change.

The effect of phosphorus on growth and cluster-root formation in the Chilean Proteaceae: Embothrium coccineum (R. et J. Forst.)

2010

One of the main factors that favours the formation of cluster roots is a low supply of phosphorus (P). The soils of southern Chile are mainly formed from volcanic ash, characterized by low levels of available P. Embothrium coccineum, a Chilean Proteaceae species produces cluster roots (CR). The factors that control CR formation in Chilean Proteaceae have not been extensively studied. The objective of this work was to assess the effects of P on the growth and cluster-root formation of E. coccineum. Plants were produced from seeds collected at two different locations: Valdivia and Pichicolo both at 39ºS. They were cultured under similar greenhouse conditions, from June to September, watered twice a week using: distilled water (W), full strength Hoagland's nutrient solution (H) or Hoagland without P (H-P). At the end of the experiment, height, total dry biomass, number of cluster roots (CR) per plant, CR /total root weight, were measured. Also acid exudation of CR was assayed using bromocresol purple on sterile agar plates. Treatments significantly affected growth and proportion of CR, the highest growth was observed with H. Under all treatments plants produced a similar number of CR. However, the proportion of CR biomass was higher with W and H-P than with H. Plants under W exhibited the lowest growth and low shoot/root ratio. Acid exudation of CR was not detectable in our experiment. These results are discussed comparing CR formation in low P conditions on Lupinus albus and other Proteaceae species, and the possible role of CR formation in E. coccineum considering its wide geographical distribution.

“…Hay estudios que señalan una reducción en la diversidad en la fauna del suelo como efecto de la tala de árboles (por alteraciones en la incidencia de luz en superficie, mayores fluctuaciones térmicas y cambios en la humedad del suelo, con problemas de desecación superficial, agregación en superficie de grandes cantidades de desechos orgánicos, como ramas, hojas, cortezas, compactación del suelo o por el daño antropocéntrico), por lo que se altera la viabilidad del suelo para la reforestación (Navarrete et al, 2011). Por lo tanto, es necesario considerar la diversidad de microartrópodos edaficos, ya que es fundamental en para la mantención de las propiedades optimas del sustrato; por lo que los estudios de riqueza y abundancia deben complementar los diversos manejos forestales (Covarrubias & Contreras, 2004).…”

Los análisis de diversidad de microartrópodos de suelo confirman que el efecto antropocéntrico es un factor limitante en la distribución y establecimiento de poblaciones de especies edáficas. Esto se puede apreciar al ver que los sitios con mayor diversidad se encuentran las áreas conservadas (San Jerónimo Amanalco), seguidas por el área de bosque del Molino de Flores y el área en recuperación de San Luis Huexotla. Con respecto a los Lepidoptera diurnos, la mayor diversidad se encuentra asociada a los sitios conservados de bosque de Pino – Encino de San Jerónimo Amanalco, donde están registradas 29 y 31 especies, seguidos por los sitios del Molino de Flores y San Luis Huexotla, debido a que si bien son áreas aparentemente conservadas tienen un impacto ambiental debido al ecoturismo y los contaminantes ambientales.
