AI Article Synopsis
- The text discusses a myxozoan parasite found in freshwater gobies in Japan, which causes swollen abdomens in infected fish.
- Researchers analyzed genetic sequences from different goby host species and rivers, revealing high nucleotide diversity, especially in the ITS region.
- The study concluded that variations in host species significantly influence genetic differences rather than geographical locations, providing insights into the parasite's spread and its ecological effects on goby hosts.
Article Abstract
is a myxozoan parasite first reported in freshwater gobies ( spp.) from the Nagara River, Gifu Prefecture, Japan. Myxospores of form plasmodia in the visceral cavities of gobies, commonly presenting as distended abdomens. Although is a common fish genus in Japan, details of , including genetic information, remain unknown. We compared the nucleotide sequences of the ribosomal RNA gene (rDNA) of from three different host species (, , and ) caught in three different rivers in Japan (Sakai, Sagami, and Kaname). The ITS region (ITS-1, 5.8S rDNA, and ITS-2) and large subunit (LSU) rDNA exhibited 49 and 55 variable sites, respectively. The highest nucleotide diversity was observed in the ITS region (0.00962), whereas that of the LSU rDNA was 0.00187. Differences in host species, rather than rivers, were a significant factor for genetic variation in both the ITS region (62.58%; < 0.001) and LSU rDNA (55.22%; < 0.01). Significant genetic variation was observed in from compared to ( < 0.001) or ( < 0.001) from the same river. Such details are valuable for understanding parasite dispersal and its ecological impact on hosts.

With the number of invasive alien species increasing globally, the management of invaded areas is constantly seeking innovative and effective solutions. Thanks to recent technological advances, acoustic signals are increasingly used in species management, either as an indicator of the presence of species or as a stimulus to repel species from risky areas or attract species for monitoring or eradication purposes. However, acoustic-based solutions are still rarely used by freshwater managers.

Article Synopsis
- Certain animal groups underwent significant changes in morphology, allowing them to adapt to diverse environments, illustrating the concept of convergent evolution.
- Gobies, a diverse group of fishes, exhibit a variety of shapes and lifestyles, which have enabled them to colonize various habitats in Europe.
- Through analyses of body shape changes, researchers found that gobies demonstrate convergent evolution linked to their locomotion in four ecological groups, providing insights into how species adapt to their environments.

Background: Biological invasions are a major threat to global biodiversity, with freshwater ecosystems being among the most susceptible to the successful establishment of non-native species and their respective potential impacts. In Poland, the introduction and spreading of non-native fish has led to biodiversity loss and ecosystem homogenisation.
Methods: Our study applies the Dispersal-Origin-Status-Impact (DOSI) assessment scheme, which is a population-level specific assessment that integrates multiple factors, including dispersal mechanisms, origin, status, and impacts, providing a nuanced framework for assessing invasion risks at local and regional levels.

Article Synopsis
- - The Round Goby, an invasive species from the Black and Caspian seas, has successfully established itself in freshwater ecosystems, particularly in the Upper Danube river, where a study analyzed its reproductive strategies including sex ratios and gonadosomatic index (GSI) over 1.5 years.
- - In the Upper Danube, the Round Goby population was predominantly female, with observed variations in the female-to-male ratio across months, and peak GSI values occurring from April to June, indicating a specific spawning period influenced by environmental factors.
- - A literature review highlighted significant variations in spawning timing, duration, and sex ratios among different Round Goby populations, suggesting these differences are influenced by climatic and seasonal changes,
