“…Similarly, paleolimnological records from 365 lakes with current hypolimnetic (bottom-water) hypoxia show that 71, or 20%, have begun exhibiting hypoxia since AD 1720 (Jenny et al 2016a). Changes in oxygen have also been observed in single-lake studies spanning multiple decades, including Blelham Tarn, UK (Foley et al 2012), Lake Erie, USA (reviewed by Tellier et al 2022), Sau Reservoir, Spain (Marcé et al 2010, Lake Tovel, Italy (Flaim et al 2020), Lake Victoria, Kenya/Tanzania/Uganda (Hecky et al 1994), Lake Washington, USA (Edmondson 1966), Lake Zurich, Switzerland (North et al 2014), and many others.…”

Changing oxygen availability in lakes and reservoirs is a fundamental limnological challenge of our time, with massive consequences for freshwater ecosystem functioning and water quality. Cross-lake surveys, paleolimnological studies, and long-term monitoring records indicate that many lakes are exhibiting declines in both surface and bottom-water oxygen availability due to climate and land use change, though a few lakes are exhibiting increases in oxygen. By analyzing time series of oxygen monitoring data from ~400 lakes, I find that some lakes may be experiencing a decoupling of surface and bottom oxygen dynamics: variability in surface oxygen concentrations is decreasing in some lakes while variability in bottom oxygen concentrations is increasing. Changes in both oxygen concentrations and variability have many implications for lake functioning because oxygen concentrations control many ecosystem processes. Consequently, lake ecosystem provisioning and cultural services (e.g., drinking water, fisheries, recreation) will likely be impaired by declining oxygen, whereas the effects of changing oxygen on regulatory and supporting ecosystem services (e.g., nitrate removal through denitrification,

“…Despite evidence that estrogen plays a role in determining the age at which women develop PD and its effect on dopaminergic neuron function, no explanation for the disparity has emerged. Industrialization, rural areas, well water, plant-derived toxins, bacterial and viral infection, and exposure to organic solvents, carbon monoxide and carbon disulfide are some of the broad environmental factors on the prevalence of PD ( Tellier et al, 2022 ). Despite inconsistent results from various research and the difficulty of identifying specific pesticide compounds that may be connected to an increased risk of PD, pesticide exposure has recently attracted interest ( Richardson et al, 2009 ).…”

Natural substances originating from plants have long been used to treat neurodegenerative disorders (NDs). Parkinson’s disease (PD) is a ND. The deterioration and subsequent cognitive impairments of the midbrain nigral dopaminergic neurons distinguish by this characteristic. Various pathogenic mechanisms and critical components have been reported, despite the fact that the origin is unknown, such as protein aggregation, iron buildup, mitochondrial dysfunction, neuroinflammation and oxidative stress. Anti-Parkinson drugs like dopamine (DA) agonists, levodopa, carbidopa, monoamine oxidase type B inhibitors and anticholinergics are used to replace DA in the current treatment model. Surgery is advised in cases where drug therapy is ineffective. Unfortunately, the current conventional treatments for PD have a number of harmful side effects and are expensive. As a result, new therapeutic strategies that control the mechanisms that contribute to neuronal death and dysfunction must be addressed. Natural resources have long been a useful source of possible treatments. PD can be treated with a variety of natural therapies made from medicinal herbs, fruits, and vegetables. In addition to their well-known anti-oxidative and anti-inflammatory capabilities, these natural products also play inhibitory roles in iron buildup, protein misfolding, the maintenance of proteasomal breakdown, mitochondrial homeostasis, and other neuroprotective processes. The goal of this research is to systematically characterize the currently available medications for Parkinson’s and their therapeutic effects, which target diverse pathways. Overall, this analysis looks at the kinds of natural things that could be used in the future to treat PD in new ways or as supplements to existing treatments. We looked at the medicinal plants that can be used to treat PD. The use of natural remedies, especially those derived from plants, to treat PD has been on the rise. This article examines the fundamental characteristics of medicinal plants and the bioactive substances found in them that may be utilized to treat PD.

“…Hypoxia is a key global stressor in freshwater, estuarine and marine benthic ecosystems (Diaz & Rosenberg, 2008 ; Tellier et al, 2022 ) that is predicted to increase worldwide due to ongoing human-induced eutrophication and global warming (Villnäs et al, 2012 ). Both zebra and quagga mussels are intolerant of even moderate hypoxia; thus, monitoring the occurrence and length-frequency distribution of Dreissena spp.…”

Ecosystem services provided by the exotic bivalves Dreissena polymorpha, D. rostriformis bugensis, and Limnoperna fortunei

The ecosystem services approach to conservation is becoming central to environmental policy decision making. While many negative biological invasion-driven impacts on ecosystem structure and functioning have been identified, much less was done to evaluate their ecosystem services. In this paper, we focus on the often-overlooked ecosystem services provided by three notable exotic ecosystem engineering bivalves, the zebra mussel, the quagga mussel, and the golden mussel. One of the most significant benefits of invasive bivalves is water filtration, which results in water purification and changes rates of nutrient cycling, thus mitigating the effects of eutrophication. Mussels are widely used as sentinel organisms for the assessment and biomonitoring of contaminants and pathogens and are consumed by many fishes and birds. Benefits of invasive bivalves are particularly relevant in human-modified ecosystems. We summarize the multiple ecosystem services provided by invasive bivalves and recommend including the economically quantifiable services in the assessments of their economic impacts. We also highlight important ecosystem disservices by exotic bivalves, identify data limitations, and future research directions. This assessment should not be interpreted as a rejection of the fact that invasive mussels have negative impacts, but as an attempt to provide additional information for scientists, managers, and policymakers.
