Proposal to synonymize Neoplagioporus Shimazu, 1990 with Urorchis Ozaki, 1927; taxonomic revision and the description of Urorchis takahaya n. sp.

Urorchis Ozaki, 1927 and Neoplagioporus Shimazu, 1990 (Digenea: Opecoelidae: Sphaerostomatinae) comprise species parasitic in freshwater fishes of eastern Asia, although the status of these genera is questionable. We revised these genera, primarily using evidence from a molecular phylogeny based on nuclear ribosomal DNA, including new sequences of four known and one new species. Urorchis was part of the clade of Neoplagioporus species, rendering the genus Neoplagioporus paraphyletic.

An efficient electrocatalytic in-situ hydrogen peroxide generation for ballast water treatment with oxygen groups.

The in-situ electrochemical production of hydrogen peroxide (HO) offers a promising approach for ballast water treatment. However, further advancements are required to develop electrocatalysts capable of achieving efficient HO generation in seawater environments. Herein, we synthesized two-dimensional lamellated porous carbon nanosheets enriched with oxygen functional groups, which exhibited exceptional performance in HO electrosynthesis.

Understanding and managing nutrient pollution in peri-urban wetlands: The Ciénegas del Lerma, Mexico.

Nutrient pollution has been broadly studied in developed countries, where the primary source is often agricultural diffuse pollution. However, more research is needed in developing countries with a predominance of low-income households, insufficient public service infrastructure, pressure from urban expansion, and scarce information. In this research, centered on the Lerma Cienega protected wetlands in a peri-urban area of Toluca city in Mexico, a socio-ecological systems framework was applied to study the nutrient pollution problem and recommend nutrient control measures.

Annual migrations, vertical habitat use and fidelity of Atlantic bluefin tuna tracked from waters off the United Kingdom.

Understanding the spatial ecology of commercially exploited species is vital for their conservation. Atlantic bluefin tuna (Thunnus thynnus, ABT) are increasingly observed in northeast Atlantic waters, yet knowledge of these individuals' spatial ecology remains limited. We investigate the horizontal and vertical habitat use of ABT (158 to 241 cm curved fork length; CFL) tracked from waters off the United Kingdom (UK) using pop-up satellite archival tags (n = 63).

Regional patterns and climatic predictors of viruses in honey bee (Apis mellifera) colonies over time.

Honey bee viruses are serious pathogens that can cause poor colony health and productivity. We analyzed a multi-year longitudinal dataset of abundances of nine honey bee viruses (deformed wing virus A, deformed wing virus B, black queen cell virus, sacbrood virus, Lake Sinai virus, Kashmir bee virus, acute bee paralysis virus, chronic bee paralysis virus, and Israeli acute paralysis virus) in colonies located across Canada to describe broad trends in virus intensity and occurrence among regions and years. We also tested climatic variables (temperature, wind speed, and precipitation) as predictors in an effort to understand possible drivers underlying seasonal patterns in viral prevalence.

Integrated use of electrochemical anaerobic reactors and genomic based modeling for characterizing methanogenic activity in microbial communities exposed to BTEX contamination.

In soil polluted with benzene, toluene, ethylbenzene, and xylenes (BTEX), oxygen is rapidly depleted by aerobic respiration, creating a redox gradient across the plume. Under anaerobic conditions, BTEX biodegradation is then coupled with fermentation and methanogenesis. This study aimed to characterize this multi-step process, focusing on the interactions and functional roles of key microbial groups involved.

Active phytoextraction of toluene shifts the microbiome and enhances degradation capacity in hybrid poplar.

Hybrid poplars are widely recognized for their effectiveness in remediating subsurface aromatic hydrocarbon contaminants, including benzene, toluene, ethylbenzene, and xylene isomers (BTEX). While BTEX compounds are frequently found in the transpiration streams of poplars at contaminated sites, the microbial dynamics within these trees, particularly in response to hydrocarbon exposure, remain underexplored. This study utilized high-throughput amplicon sequencing to investigate the trunk microbiome in hybrid poplars at a field-scale toluene phytoremediation site.

Prioritising relevant polychlorinated naphthalene (PCN) congeners for human dietary exposure studies.

Following a decline in the production and use of polychlorinated naphthalenes (PCNs) and the restrictions introduced by the Stockholm Convention, dietary intake represents the most significant pathway of human exposure to these dioxin-like contaminants. PCNs occur ubiquitously in foods, originating from the legacy of historical production that is now globally redistributed, as well as from ongoing industrial and domestic combustion sources which have a stronger influence on occurrence patterns in countries where they were not produced. Recent studies have benefited from a wider set of available PCN reference standards, enabling more accurate reporting of a diverse range of congeners.

Yield increment and transcriptome response caused by blue light treatment in Hericium coralloides.

Background: Hericium coralloides is a traditional edible and medicinal mushroom. Light is a key factor in forming fruiting bodies of fungi; however, the effects of different light on the yield and morphogenesis of H. coralloides are still unknown.

Increase or decrease? Impact of straw return on farmers' agricultural income in Jianghan Plain, Central China.

In the context of emphasizing on the food production, clean air guarding and sustainable development of agriculture, straw returning practices have been widely promoted, however, most studies have not linked straw returning adoption and smallholder's agricultural income in double-season rice cropping system. Based on a face-to-face survey data from 797 farmers in Jianghan Plain, Central China, we filled this gap by using the endogenous switching regression model to estimate the impact of farmer's straw returning on their agricultural income. The evidences show number of family laborers and technical training are the main factors influencing farmers' adoption of SR.

Linking Foraging Behaviour and Habitat Preferences During Moult Across Multiple Populations of Red-Throated Diver.

Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

Persistent humid climate favored the Qin and Western Han Dynasties in China around 2,200 y ago.

The Qin and Western Han dynasties (221 BCE to 24 CE) represent an era of societal prosperity in China. However, due to a lack of high-resolution paleoclimate records it is still unclear whether the agricultural boost documented for this period was associated with more favorable climatic conditions. Here, multiparameter analysis of annually resolved tree-ring records and process-based physiological modeling provide evidence of stable and consistently humid climatic conditions during 270 to 77 BCE in northern China.

Temporal dynamics in a red alga dominated geothermal feature in Yellowstone National Park.

Alga-dominated geothermal spring communities in Yellowstone National Park (YNP), USA, have been the focus of many studies, however, relatively little is known about the composition and community interactions which underpin these ecosystems. Our goal was to determine, in three neighboring yet distinct environments in Lemonade Creek, YNP, how cells cope with abiotic stressors over the diurnal cycle. All three environments are colonized by two photosynthetic lineages, and , both of which are extremophilic Cyanidiophyceae red algae.

Methylmercury contamination in Mediterranean seafood: Exposure assessment and cost of illness implications.

Methylmercury (MeHg) is a widespread contaminant that bioaccumulates in marine food webs, including those in the Mediterranean sea. It poses serious health risks, especially to developing infants and children, where exposure can cause neurological damage and developmental delays. In addition to health concerns, high MeHg levels in seafood can lead to economic losses through cognitive impairments that reduce productivity.

Shifts in the ecological drivers influence the response of tree and soil carbon dynamics in central Himalayan forests.

Understanding and regulating global carbon relies crucially on comprehending the components and services of forest ecosystems. In particular, interactions that govern carbon storage in trees, soil, and microbes, driven by factors like vegetation structure, function, and soil characteristics, remain poorly understood, especially in the central Himalayas. To address this gap, we investigated carbon storage in tree aboveground biomass, root biomass, and soil across different vegetation types.

Animal health and welfare as a public good: what do the public think?

This paper presents a novel perspective on an evolving policy area. The UK's withdrawal from the EU has led to the creation of a new Agriculture Act and proposals for significant changes to the way farming subsidies are structured in England. Underpinned by a 'public money for public goods' approach, where public goods are those outputs from the farm system which are not rewarded by markets, yet which provide benefits to many members of society.

Coordination of care reduces conflict and predation risk in a cooperatively breeding bird.

When two or more individuals cooperate to provision a shared brood, each carer may be able to maximize their payoffs by coordinating provisioning in relation to what others are doing. This investment "game" is not simply a matter of how much to invest but also of the relative timing of investment. Recent studies propose that temporal coordination of care in the forms of alternation (i.
