“…Clearly, the single sampling event performed for this study is not sufficiently representative for a comparison of temporal change; nevertheless, we can assume that the decrease in prevalence and abundance of Unio may be related to the introduction of the Chinese pond mussel, an invasive species now spreading in European waters (Konečný et al ., 2018). The species has been recorded in the lower Oder since 2003 (Domagała et al ., 2003), where it potentially outcompetes native unionid mussels (Poznańska‐Kakareko et al ., 2021). In our sample, both prevalence and abundance were slightly higher for Chinese pond mussel glochidia than Unio sp., suggesting that pumpkinseed act as a competent host for this Asian mussel species.…”

In Poland, distribution of non‐native pumpkinseed Lepomis gibbosus (Centrarchidae) is strictly limited to the Oder river basin, where it was introduced in the early 20th century. Recently, several populations have been found in waterbodies adjacent to the Oder, particularly in its lower reaches. In this study, we compare the genetic relatedness of populations in the Oder basin with other European populations using nuclear (microsatellite) and mitochondrial (partial cytochrome c oxidase subunit I; cox1) markers. Microsatellite analysis indicated that four populations in the lower Oder form a separate cluster, while one in the middle Oder clustered with Danubian populations, from where probably having been introduced. Microsatellite data suggested that the lower Oder populations differ from other non‐native European populations, making it impossible to estimate the source of introduction. Nevertheless, analysis of cox1 indicated that Oder pumpkinseeds belong to the same haplotype as the vast majority of European populations. Parasitological examination confirmed the presence of two North American species, the monogenean Onchocleidus dispar and trematode Posthodiplostomum centrarchi, in the lower Oder, both previously unknown in the region. Fifteen other parasite species were acquired, including glochidia of invasive Sinanodonta woodiana. In the middle Oder, parasite infection was more limited. Fish from the Gryfino Canal, considered one of the most invasive populations in Europe, showed the highest parasite abundance and diversity, and the highest somatic condition and growth rate due to warm water released from the Dolna Odra power plant. Our results highlight significant differences in somatic condition and parasite infection in long‐established non‐native pumpkinseed populations in the same river system, reflecting mainly environmental conditions.

“…Unionids will burrow in high flow, which may result during flooding and high depths, as a way to stay in place and avoid being swept downstream due to the shear stress and unstable substratum that results from high flow (Strayer, 1999;Steuer et al, 2008). When burrowed to take refuge during flooding conditions, movement of unionids would be presumably minimal, as large movements could expose them to extreme depth changes (and high flows), causing potential dislodgement (Poznańska-Kakareko et al, 2021). This behavior in relation to high depth and flow was seen in our study, at GR specifically, where more than half of the time L. recta individuals were fully or partially burrowed, and not burrowed only 4% of the time.…”

Native freshwater mussels (unionids) are indicators of water quality, with unique behaviors and movement patterns. Many of these species are endangered, yet basic movement and co-occurring community data are lacking for successful unionid conservation. In this study, movement, community, and habitat use among Ligumia recta , an endangered unionid in Michigan, were analyzed across four rivers in central Michigan. The effects of sex, community, substrate use, and other abiotic factors on the movement and occurrence of L. recta were quantified. 24 L. recta individuals were found with variable male:female ratios and were monitored bi-weekly. Over the recapture period, L. recta moved an average minimum convex polygon of 1.43 m 2 per day but was variable among rivers. 19 unionid species were found occurring with L. recta ; ~13 species in the same river reach as L. recta and ~5 species in closer proximity to L. recta . The tribe Lampsilini most often occurred in close proximity to L. recta . This study identified basic movement and occurrence patterns of L. recta and provides a better understanding of the status of L. recta in Michigan. Our study highlights useful methods in understanding imperiled unionids, expanding the knowledge of their movement, behavior, community assemblages, and habitat use.

“…Finer substrates, such as silt, may contain more organic matter as a food source for filter-feeding mussels (Lara & Parada, 2009), although silt is also considered to be detrimental to feeding and respiratory activity in mussels (Roper & Hickey, 1995;Brim Box & Mossa, 1999). A more likely explanation for a preference for finer substrates may be that they enhance burrowing efficiency (Lewis & Riebel, 1984;Morales et al, 2006;Poznańska-Kakareko et al, 2021; although see Hyvärinen et al, 2021 for a contrary finding with juvenile mussels). Burrowing may provide protection against drought (Amyot & Downing, 1997;Gough et al, 2012), which would be an important adaptation in regions with non-perennial rivers, such as south-western Australia, where river drying is a regular annual occurrence.…”

Freshwater mussels are important functional components of aquatic ecosystems. Westralunio carteri is a threatened freshwater mussel species, endemic to south-western Australia, which has suffered a recent, dramatic decline in range. The density, size structure and distribution of adult mussels of this species within river reaches were investigated using quadrat searches and modelled against a range of microhabitat factors. Mussels were found from 26 sites in 14 different rivers at a mean density of 28.4 ± 2.3 individuals m−2. The distribution of W. carteri was highly aggregated within river reaches. The most important factors explaining mussel distribution were substrate grain size, substrate debris and distance from the riverbank, with finer substrate, the presence of woody debris and proximity to the riverbank associated with greater abundance of mussels. In all rivers where mussels were found, most populations appeared to be actively recruiting. However, no mussels were found in six sites, despite them having been recorded as present within the last 20 years, which suggests that the range of the species is still in decline. The identification of microhabitat requirements for W. carteri will assist in identifying suitable release sites for translocation and/or captive propagation, which may be required to prevent extinction of the species.
