“…Translocation of microplastics is a prerequisite process for bioaccumulation and biomagnification to occur. Evidence of translocation of microplastics within wild‐caught crayfish provided within this study therefore provides crucial support for the inclusion of crayfish in future work exploring impacts of bioaccumulation and biomagnification processes, such as ecotoxicology (Anbumani & Kakkar, 2018 ; Mallik et al, 2021 ) and impaired physiological performance (Mkuye et al, 2022 ; Welden & Cowie, 2016 ). In our study, microplastics were observed within tail muscle tissue; however, no organs outside of the gastrointestinal tract were sampled.…”

Microplastics are a globally pervasive pollutant with the potential to directly impact species and accumulate in ecosystems. However, there remains a relative paucity of research addressing their accumulation in freshwater ecosystems and a near absence of work in crayfish, despite their high ecological and economic importance. This study investigated the presence of microplastics in the invasive signal crayfish Pacifastacus leniusculus along a stream urbanization gradient. The results demonstrate a ubiquitous presence of microplastics in crayfish digestive tracts at all sites and provide the first evidence of microplastic accumulation in tail tissue. Evidence of a positive linear trend was demonstrated between microplastic concentration in crayfish and upstream urban area size in generalized linear models. Evidence for a positive effect of the upstream urban area and a negative effect of crayfish length on microplastic concentrations in crayfish was demonstrated in multiple generalized linear regression models. Our results extend the current understanding of microplastics presence in freshwater ecosystems and demonstrate their presence in crayfish in the wild for the first time.

“…These microplastics also interfere with the reproductive systems of marine animals, leading to a decline in population numbers. Studies also show that microplastics can disturb the behavior and physiology of marine animals, such as reducing their swimming ability and increasing their susceptibility to predators [109][110][111].…”

In recent years, there has been mounting concern about the bearing of microplastics on human health and the comprehensive natural environment. These particles come from a variety of sources, such as soaps, personal care products, and the rundown of bigger plastic items. The impacts of microplastics on marine life and other ecosystems are substantial, including ingestion by marine animals, interference with their reproductive systems, and even death. The economic implications of microplastics are also significant, with industries, such as fishing and tourism being affected by the presence of microplastics in the environment. Exposure to microplastics can also pose potential health risks to humans, including respiratory and digestive problems, as well as disrupt sleep, contribute to obesity, and increase the risk of diabetes. To address this issue, policies and initiatives have been put in place to reduce microplastic pollution, but there are challenges that need to be overcome, such as lack of awareness, limited resources, and ineffective regulations. Further research is also needed to fully understand the impacts of microplastics on our health and to develop effective strategies to mitigate the problem. In this article, we have discussed the requirement of a multifaceted approach including reducing plastic use, promoting proper disposal and recycling of plastic waste, developing innovative technologies for capturing and removing microplastics from the environment, raising public awareness, and implementing effective regulations and policies. It is only through concerted efforts and collaboration between individuals, industries, and governments that the threat of microplastics can be tackled.

“…Further research is necessary to explore the potential of marine bivalves to adapt to heat stress through this mechanism. Additionally, more research is needed to gain a deeper understanding of the physiology of these organisms, including their ability to adapt to cold extremes (Masanja et al, 2023)microplastics (Mkuye et al, 2022), the allocation of energy under different nitrite and ammonia concentrations (Nkuba et al, 2021), and how their behavior and growth rate may be impacted by increased frequency and intensity of heat stress.…”

As the global ocean continues to experience the consequences of an increase in the frequency and intensity of heat waves, the trend is expected to persist into the 21st century, with a projected tripling of heat waves by 2040. This phenomenon poses a significant threat to marine ecosystems and the survival of marine organisms, including the ecologically and economically vital bivalves. Bivalves are vulnerable to harm from heat stress at various levels of biological organization, and their growth can be negatively impacted by high temperatures, potentially leading to mass mortalities and posing a threat to ecosystem quality and food security. In light of these concerns, this review aims to provide a comprehensive examination of the effects of heat stress on bivalves. It summarizes the physiological and biochemical changes that bivalves undergo in response to extreme heat events and offers an overview of the strategies they employ to mitigate their impacts. A better understanding of the underlying mechanisms of bivalve responses to heat stress is crucial in order to fully appreciate the impact of these events on these organisms. This review synthesizes the current knowledge on heat stress in bivalves and highlights the importance of further research in this area. By providing a comprehensive overview of the physiological and biochemical changes that bivalves experience during heat stress and the strategies they use to mitigate its impact, this review aims to support the development of more effective approaches to minimize heat stress in bivalves.
