- Abstract:
- ... Microbial communities are the main drivers of biogeochemical cycling of multiple elements sustaining life in the ocean. The rapidity of their response to stressors and abrupt environmental changes implies that even fast and infrequent events can affect local transformations of organic matter and nutrients. Modern molecular techniques now allow for monitoring of microbial activities and functions i ...

- Abstract:
- ... Recent studies have proposed barium isotopes as a novel proxy for studying primary productivity in paleo-oceangraphical studies and elements cycling through the critical zone. Pristine marine carbonates are generally assumed to preserve Ba isotope compositions of ancient seawater. However, Ba incorporated in or adsorbed on detrital minerals such as clays in impure carbonates may limit the accurate ...

The present work investigated the potential of acidogenesis digestate rich in volatile fatty acids (Bio-DAcid) and methanogenesis digestate rich in ammonia (Bio-DMeth) as a green method for the pretreatment of rice straw and biomethane production. After pretreatment with Bio-DMeth for 48 h, a maximum hemicellulose reduction of 22.4% was recorded, while 48 h of Bio-DAcid showed the lowest reduction ...

- Abstract:
- ... Nurse plants drive the assembly of facilitated communities and commonly promote plant–soil feedbacks, and are thus recognized as key engineers in abiotically stressful ecosystems. The literature neglects; however, the role of the communities which benefit from the presence of the nurse as contributors to soil ecosystem functions. We hypothesized that the nurse and its beneficiaries synergistically ...

Thus, adsorption of phosphate by sediments from Lake Dianchi, a eutrophic lake, was investigated in this study. Importantly, the influence of dissolved organic matter (DOM) with fulvic acid (FA) as a representative example on these processes was further studi ...

Microbial Fe(III) reduction is a significant driving force for the biogeochemical cycles of C, O, P, S, N, and dominates the natural bio-purification of contaminants in groundwater (e.g., petroleum hydrocarbons, chlorinated ethane, and chromium). In this review, the mechanisms and environmental significance of Fe(III) (hydro)oxides bioreduction are summarized. Compared with crystalline Fe(III) (hy ...

This has contributed to widespread water quality degradation influenced by processes and hydrologic pathways that differ from warm region analogues. In cold regions, snowmelt is often a dominant period of nutrient loss. Freeze–thaw processes contribute to nutrient mobilization. Frozen ground can limit infiltration and interac ...

There is an increasing body of studies that show that land use intensification and homogenisation in agriculture landscapes, aimed at increasing food provisioning, decline other ecosystem services. Agroecological management has been proposed as an alternative to conventional agricultural management because of its presumed capacity to rehabilitate degraded ecosystem services. In this study we teste ...

Temperate forests have relatively low liana diversity compared to tropical forests, and it is believed this discrepancy has allowed nonindigenous lianas to disrupt temperate native communities to a greater degree. Due to their nature as structural p ...

Arbuscular mycorrhiza fungi’s (AMF) role in plant nutrition and stress management is well known, but very few researches and studies have been conducted so far on the fungal ability to reduce different nutrient losses (runoff, leaching and volatilization) from the soil system. This important ecosystem service of AMF had been neglected largely. From the recent findings, it has been confirmed that m ...

In this study, Undaria pinnatifida was exposed to As(V) (0, 0.1, and 1 μM) and phosphate (P; 1 and 10 μM) in seawater under laboratory-controlled conditions for up to seven days to analyze As biotransformation. The growth rates and chlorophyll fluorescence of the alga w ...

In this study, a new As-resistant bacterial strain Leclercia adecarboxylata As3-1 was isolated and its associated mechanisms in As resistance and detoxification were evaluated based on genome sequencing and gene annotations. After subjecting strain As3-1 to medium containing arsenate (AsV), AsV reduction ...

- Abstract:
- ... Artificial lighting at night (ALAN) produced by urban, industrial, and roadway lighting, as well as other sources, has dramatically increased in recent decades, especially in coastal environments that support dense human populations. Artificial “lightscapes” are characterized by distinct spatial, temporal, and spectral patterns that can alter natural patterns of light and dark with consequences ac ...

Consequently, soil drainage maps represent crucial tools for crop, forest and environmental management purposes. As extensive field surveys are time- and resource-consuming, alternative spatial modelling techniques have been previously applied ...

- Abstract:

To alleviate hypoxic conditions, a trial side-stream supersaturation (SSS) oxygenation plant was established at Guildford (39 km upstream of the estuary mouth) in 2009. After notable success, a second plant was constru ...

Groundwater table fluctuation during natural and anthropogenic processes can facilitate the interaction between oxygen (O2) from the unsaturated zone and ferrous iron (Fe2+) from the saturated zone. In light of previous findings that Fe(III)-reducing bacteria can be killed by the reactive oxidants produced from Fe2+ oxidation under static oxic conditions, we hypothesize that Fe(III)-reducing bacte ...
