    #Glyphosate-Based #Herbicides and Their Potential Impact on the #Microbiota of Social #Bees

    Abstract

    "Bee pollination is essential for terrestrial #ecosystems and crop production. However, the species richness of wild bees and other #pollinators has declined over the past 50 years, with some species experiencing dramatic decreases. A key factor in maintaining bee health is their #GutMicrobiota, which plays an essential role in digestion, nutrient absorption, immune function, and resistance to pathogens. Disruptions to this microbiota can severely impact bee health, rendering them more susceptible to diseases and environmental stressors. Glyphosate, one of the most widely used herbicides, has been extensively studied for its effects on various organisms, with increasing evidence indicating its potential to disrupt bee microbiota. This review explores recent research on the effects of glyphosate and its formulations on the gut microbiota of #honeybees and #bumblebees. It examines species-specific responses, methodological approaches, and broader ecological implications. While evidence indicates that glyphosate can alter the gut microbiome in some bee species, its effects vary depending on exposure conditions, species, and the composition of microbial communities. Additionally, glyphosate formulations containing surfactants may exacerbate these effects. Given the endocrine-disrupting properties of glyphosate, further research is needed to understand the long-term consequences of exposure, especially its impact on hormonal regulation and bee resilience to #EnvironmentalStressors."

    Highlights

    • The risk of irritable bowel syndrome is higher in areas of high pesticide exposure.
    • Agronomic criteria were used to categorize pesticide exposure in the study population.
    • A total of 18,807 cases of irritable bowel syndrome were studied.
    • Environmental pesticide exposure is linked to irritable bowel syndrome.

    Abstract
    The agricultural model in southern #Spain is highly productive, mainly due to the intensive cultivation under plastic. Despite strict pesticide regulation, human exposure to pesticides in the environment has been connected to an increase in diseases such as #CeliacDisease. Certain pesticides have also been associated to the disruption of the intestinal #microbiota, which has been xtied to the development of irritable bowel syndrome (IBS). A case-control study was conducted in Andalusia, south #Spain, to assess the prevalence and risk of IBS related to pesticide exposure. This research found a high prevalence of IBS in #Andalusia between 2000 and 2021 in areas with high pesticide exposure using agronomic criteria. Furthermore, the odds ratio for IBS was significantly higher in the population with high pesticide exposure. This study suggests that pesticides may be involved in IBS, whereas more research is needed to determine the role of pesticides in IBS symptomatology.

    Excerpts: "[In the locations of the study], the most commonly used insecticides are #organophosphates (primarily chlorpyrifos), N-methylcarbamates, macrocyclic lactones, #neonicotinoids, and pyrethroids. #Fungicides frequently used in plastic greenhouses include (di) thiocarbamates, conazoles, dicarboximide), anilino-pyrimidines, and copper salts. Bipyridyl (paraquat, diquat), organophosphonates (#glyphosate), chlorotriazine, and phenylurea are the herbicides most popularly used in the study areas (García-García et al., 2016)."

    Studies on Rats

    "A wide range of environmental pollutants, including heavy metals, insecticides, herbicides, and pesticides, can cause gut dysbiosis (Jin et al., 2015, Lin et al., 2020, Reygner et al., 2016). As suggested in our findings, there is also an increased risk of IBS precisely in pesticide-heavy areas and particularly in women. Previous research have found sexually dimorphic metabolic effect after pesticides exposures (Lukowicz et al., 2018). In this regard, #Roundup®, a glyphosate-based herbicide (#GBH) widely used in Andalusian crops, can increase the #Bacteroidetes group while decreasing the #Lactobacillaceae family in fecal samples of female rats (Lozano et al., 2018). Similarly, chronic glyphosate exposure reduces Corynebacterium, Firmicutes, Bacteroidetes, and Lactobacillus in mice following GBH administration (Aitbali et al., 2018). Exposure to fungicides such as imazalil can also alter the composition of the GM after acute and chronic administration. Specifically, in mice, imazalil increases the relative abundance of Firmicutes, Proteobacteria and Actinobacteria while decreasing the abundance of Bacteroidetes (Jin et al., 2016). Insecticides such as chlorpyrifos, diazinon and aldicarb also disrupt the GM of rats and mice (Aitbali et al., 2018, Gao et al., 2019, Gao et al., 2017, Joly et al., 2013). This modification has been associated with increased intestinal permeability and bacterial translocation in the case of chlorpyrifos (Condette et al., 2014). Diazinon inhibits several SCFA-producing genera in the Lachnospiraceae family, which operate as an energy substrate for colonic epithelial cells, altering energy harvesting in the intestinal epithelium (Gao et al., 2017)."

  7. Saps els gossos, que sempre volen el plat de l'altre? Doncs sembla que els humans fem el mateix.
    Ho fem amb les medicines, i ho fem amb els aliments.
    Ara mateix hi ha un munt de gent fent Kimchi i kombutxa i koji, i molt poca fent olives.

    I no tinc res en contra dels fermentats foranis, però aprendre coses noves, sense conservar els coneixements propis, ho trobo absurd.

    No se m'acudeix un aliment més mediterrani que les olives. I a més, com a fermentat, són meravelloses.

    A part de ser probiòtiques, les olives en sí són plenes de compostos benèfics, i a més s'adoben amb herbes medicinals, que alhora tenen molts compostos benèfics, que les olives atraparan de forma molt eficient, fent-los disponibles a la nostra digestió.
    Perquè hi ha compostos liposolubles (solubles en oli) i hidrosolubles (solubles en aigua), i les olives contenen oli i aigua i per tant els poden extraure tots

    I a més a més, són delicioses.

  10. Pregerminar és germinar parcialment les llavors.
    És a dir, posar-les a germinar, però menjar-les abans de què hagin germinat del tot.
    Per exemple per les llenties, serveix tenir-les en remull 3 o 4 dies. Aleshores, cal canviar l'aigua un parell de vegades al dia per evitar que es facin malbé, i mantenir-les a les fosques, com ara dins una olla tapada.

    🌱Desperta la llavor i fa més biodiponibles els seus nutrients. Això vol dir, que t'alimentaran més.
    🌱Renta els antinutrients de la coberta de la llavor, com per exemple els fitats. Això també farà que t'alimenti més i digereixis millor, doncs els antinutrients bloquegen nutrients i inhibeixen enzims.
    🌱Cultiva els microorganismes que formen part de la microbiota que la planta mare ha transmès a la descendència i que es troba a la superfície de la llavor.
    🌱 Redueix considerablement el temps de cocció. Guanyes temps, redueixes el consum energètic i escalfes menys la casa (interessant a l'estiu). Des del punt de vista energètic de la MTM, els aliments amb coccions breus, ens donen menys calor interna, són més frescos, i això també és una bona cosa quan a fora fa calor.

    L'aigua dels 2 primers remulls, és millor llençar-la. Estarà plena de fitats, que tenen la funció d'inhibir el creixement vegetal, per evitar que la llavor germini abans que l'aigua acumulada al terra sigui suficient perquè la planta faci la primera estirada completa. Pots fer-la servir per tirar de la cadena.
    Les següents, les pots fer servir per regar ja que, per contenir hormones vegetals, estimularà el creixement de les plantes, o beure'n una part, ja que conté la microbiota pròpia de la llavor i és per tant un probiòtic.

  12. Borrowing this from Wader Quest's fb page.
    "This is a fantastic video, it's about the relatively recent and vital discovery of the importance of biofilm, that green slime on the surface of mudflats.
    It seems that this substance is invaluable to migrating waders and, in this case, particularly to the delightful Western Sandpiper, a declining species. The video highlights their reliance on this food source for their very survival. Without it, they would be malnourished, meaning most would not be able to complete their migration and many would simply die. This would cause a decline in the population since, as a species. they would not be able to breed in sufficient numbers to maintain the population, which ultimately could lead to their extinction. Roberts Bank in British Columbia, Canada is a globally classified Important Bird Area and a key stopover for Western Sandpipers. Distressingly, its mudflats and their biofilm covering, are threatened by the proposed expansion of the Fraser Port Authority, the so-called Roberts Bank T-2 development. If allowed to go ahead this would mean additional significant habitat loss that would further endanger the species. This situation typifies a wider crisis affecting waders across the planet, highlighting the urgent need for collaboration among researchers, conservationists, and communities to protect these vital ecosystems, and the species that use them, which are becoming increasingly at risk of extinction."

  13. #Trump #EPA’s Next Move: Making It Harder to Sue for Getting Cancer from #Roundup

    The corporation behind Roundup #herbicide has paid out nearly $11 billion in lawsuits. Now it's backing an EPA rule that would stop the bleeding.

    by Schuyler Mitchell, March 21 2025

    "Last August, 11 industry-friendly red states, led by Nebraska and Iowa, submitted a 436-page petition asking the agency to amend its labeling rules under the Federal #Insecticide, #Rodenticide, and Fungicide Act, or #FIFRA. The proposed rule change would explicitly prohibit states from labeling #pesticides and #herbicides with warnings about cancer, #BirthDefects, and reproductive harm if those notices contradict the EPA’s risk assessment.

    "The states made clear that their ultimate goal is to thwart future lawsuits against pesticide manufacturers. Their petition argued that recent court rulings have created a 'gap in FIFRA’s regulatory framework' that the proposed rule change would plug.

    "In January, in a move initiated by the Biden administration, the EPA took a first step of accepting public comment on the rule-making petition, with a deadline of March 24 — though this step is exploratory and does not mean a new rule will be issued. Still, the EPA’s decision could have disastrous consequences if Donald Trump’s second administration is as friendly to the #ChemicalIndustry as it was in his first.

    "'It’s telling of the lengths that pesticide manufacturers will go to make sure that nothing interferes with their profit margins,' said Brett Hartl, government affairs director at the Center for Biological Diversity. 'There’s a reality that the industry itself generates much of the data, and they say it’s safe, and then EPA approves that determination.”
