Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Exploring plant tolerance to biotic and abiotic stresses [PDF]

open access: yes, 2007
Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Arabidopsis thaliana was used as a model plant to study the responses

Toward a Cannabis Terroir: Untargeted Metabolomic Profiling of Authentic Samples Using Gas Chromatography–High‐Resolution Mass Spectrometry (GC‐HRMS) and Liquid Chromatography–High‐Resolution Tandem Mass Spectrometry (LC‐HRMS/MS)

open access: yesDrug Testing and Analysis, EarlyView.
This study developed a comprehensive metabolomics workflow using GC‐HRMS and LC‐HRMS/MS and analyzed 35 CBD‐type cannabis flowers grown under varying conditions. Key discriminative compounds enabled classification by chemical phenotype and cultivation environment. The results showed that environmental factors influence chemical profiles, supporting the

Functional analysis of CcDREB1D promoter region from two genotypes of Coffea canephora through genetic transformation of Nicotiana tabacum : S03P08 [PDF]

open access: yes, 2013
Although some studies in plant physiology resulted in a better understanding of the mechanisms involved in drought tolerance in coffee, knowledge about the metabolic and molecular changes involved in the response of the coffee plant to water deficit ...

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

open access: yesDeep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Habitat heterogeneity overrides local processes to drive the species–area relationship of benthic macroinvertebrates in shallow floodplain lakes

open access: yesEcography, EarlyView.
The species–area relationship (SAR) on islands describes how the numbers of species increase with increasing island size (or island‐like habitat, such as lakes). Despite its conceptual importance, there is considerable uncertainty surrounding its shape in freshwater lakes, as well as the potential mechanisms that underlie the SAR.
