Efectos de la aplicación de biochar de alperujo como enmienda en suelos de oliv...

La agroindustria del aceite de oliva es un importante sector económico en los países mediterráneos, cuya producción va acompañada de la generación de enormes cantidades de residuos orgánicos. La reciente proliferación de olivares superintensivos, más rentables, genera una mayor demanda de agua para riego y está aumentando la producción de estos residuos. La conversión de los residuos de almazara en biochar medi...

Marcadores moleculares subrogados a la repelencia al agua en suelos afectados p...

La repelencia al agua del suelo (RAS) se atribuye a la acumulación de compuestos hidrofóbicos (lípidos), pero su extracción no siempre elimina la RAS, lo que sugiere que componentes macromoleculares no extraíbles también pueden estar relacionados con una RAS. Se han estudiado suelos quemados (B) y control (UB) del Parque Nacional de Doñana (Huelva, España) bajo dos tipos de vegetación (alcornoque y brezo) y fra...

A multidisciplinary approach to the comparison of three contrasting treatments ...

Removing lampenflora, phototrophic organisms developing on rock surfaces in tourist cavities due to the artificial lighting, is a challenge for sustainable and appropriate long-term management of caves. Photosynthetic-based biofilms usually cause rock biodeterioration and an ecological imbalance in cave ecosystems. In this work, a detailed investigation of the effects of the 3 most commonly used lampenflora cle...

Migração da revista Conservar Património para o SARC Light no âmbito da iniciat...

A presente comunicação aborda a migração da revista Conservar Património para o Repositório Científico de Acesso Aberto de Portugal (RCAAP) através do Serviço de Alojamento de Revistas Científicas (SARC Light) lançado no âmbito da iniciativa Pub In em Maio de 2020. A discussão aqui apresentada foca-se na experiência, nas opções e nas estratégias tomadas no âmbito desta acção.; This communication addresses the m...

Impact of wildfires on subsurface volcanic environments: New insights into spel...

Siliceous speleothems frequently reported in volcanic caves have been traditionally interpreted as resulting from basalt weathering combined with the activity of microbial communities. A characteristic feature in lava tubes from Hawaii, Azores and Canary Islands is the occurrence of black jelly-like speleothems. Here we describe the formation process of siliceous black speleothems found in a lava tube from La P...

Molecular Characterization of Burned Organic Matter at Different Soil Depths an...

Soil water repellency (hydrophobicity) prevents water from wetting or infiltrating soils, triggering changes in the ecosystems. This physical property is directly correlated to the erodibility grade of a soil. Wildfire events may develop, enhance, or destroy soil hydrophobicity, modifying the erodibility grade of a soil and increasing the loss of its most reactive layer (organic matter). To assess the main orga...

Hydrophobicity of soils affected by fires: An assessment using molecular marker...

Soil water repellency (SWR) is a physical property due to a complex interaction of factors (e.g., fire, soil organic matter, soil texture) that reduces the soil water infiltration capacity. Traditionally, SWR is attributed to the accumulation and redistribution of hydrophobic compounds within soil profile. To obtain further insight into chemical compounds, which could be associated with SWR, a study was done on...

A conservation roadmap for the subterranean biome

The 15th UN Convention on Biological Diversity (CBD) (COP15) will be held in Kunming, China in October 2021. Historically, CBDs and other multilateral treaties have either alluded to or entirely overlooked the subterranean biome. A multilateral effort to robustly examine, monitor, and incorporate the subterranean biome into future conservation targets will enable the CBD to further improve the ecological effect...

Biochar amendment increases bacterial diversity and vegetation cover in trace e...

Application of biochar has been widely suggested as a remediation tool for trace element-polluted soils, but the impact of biochar on microbial communities and on native plants remain largely unknown. To overcome this knowledge gap, biochar produced from rice husk and olive pit were applied at a rate of 8 t ha−1 into a soil with two contrasting levels of trace elements (high and moderate) to study their effects...
