“…However, colder temperatures in the north Aegean Sea than in the south, fuelled by the cold outflow from the Black Sea and by intense upwelling, could be the limiting factor preventing the invasion/establishment of tropical species [ 50 ], particularly of the ectothermic ones such as P. segnis . According to Zainal and Noorani [ 51 ] the thermal tolerance of P. segnis is between 5 °C and 40 °C, beyond which its survival becomes critical. Furthermore, a study on stress resistance of P. pelagicus larvae showed a very low survival rate at 10 °C and 20 °C but the highest survival was found at a constant temperature of 30 °C [ 52 ].…”

Invasive alien species represent one of the main environmental emergencies and are considered by the scientific community as being among the leading causes of biodiversity loss on a global scale. Therefore, detecting their pathways, hotspot areas and invasion trends becomes extremely important also for management purposes. A systematic review on presence of Portunus segnis in the Suez Canal and Mediterranean Sea was carried out in order to study the invasion paths from its entry from the Red Sea into the Suez Canal (1886) until recently (2021) through ecological indicators elaborated with GIS spatial–temporal statistics. Arrival, establishment and expansion phases and areas of P. segnis in the Mediterranean were identified. Settlement areas were detected along the Suez Canal as well as in the Levantine Sea, western Ionian Sea and Tunisian plateau ecoregions. Since 2015 a persistent area has formed in Tunisia from where the species is spreading northward and eastward. The study provides an insight on the impact of P. segnis on biodiversity and ecosystem services and proposes a series of desirable management actions to mitigate the expansion of its population. Following the 8Rs model that introduces the rules to mitigate non–indigenous species pollution, six of them (Recognize, Reduce, Replace, Reuse, Remove, and Regulate) have been identified as applicable and are discussed.

“…Their heart rate had strong dependence to temperature. Their heart rhythm stability was better than polyric rhythm under high temperature condition (Kushinsky et al, 2019;Zainal and Noorani, 2019;Singh et al, 2020a;Singh et al, 2020b;Levinton et al, 2020). In contrast to vertebrates, the hearts of crustaceans have strong regenerative potential.…”

“…As one of the critical organs and a core component of the circulatory system, the heart plays an important role in various life activities such as development and reproduction ( Goepel and Wirkner, 2020 ). Currently, only a few studies have been published on the heart in crabs and these involve the influence of different environmental factors such as hypoxia and temperature on the heart rate ( Kushinsky et al, 2019 ; Zainal and Noorani, 2019 ; Singh et al, 2020a ; Singh et al, 2020b ; Levinton et al, 2020 ). The results indicated that crab performed cardiac compensation in response to declining dissolved oxygen.…”

Eriocheir sinensis is widely appreciated by the surrounding population due to its culinary delicacy and rich nutrients. The E. sinensis breeding industry is very prosperous and molting is one of the important growth characteristics. Research on the regulation of molting in E. sinensis is still in the initial stages. There is currently no relevant information on the regulatory mechanisms of heart development following molting. Comparative transcriptome analysis was used to study developmental regulation mechanisms in the heart of E. sinensis at the post-molt and inter-molt stages. The results indicated that many regulatory pathways and genes involved in regeneration, anti-oxidation, anti-aging and the immune response were significantly upregulated after molting in E. sinensis. Aside from cardiac development, the differentially expressed genes (DEGs) were relevant to myocardial movement and neuronal signal transduction. DEGs were also related to the regulation of glutathione homeostasis and biological rhythms in regard to anti-oxidation and anti-aging, and to the regulation of immune cell development and the immune response. This study provides a theoretical framework for understanding the regulation of molting in E. sinensis and in other economically important crustaceans.
