“…However, further studies and ad hoc genetic analyses would be needed to shed light on this point definitively. The phenotypic plasticity of P. parva , together with plasticity in life‐history traits (Jia et al, 2019), is considered one of its key traits allowing it to be a successful invader. Indeed, a high degree of interpopulation morphological variability has been found for this species (Kotusz, 1998; Záhorská, Kováč, Falka, et al, 2009), but also in other invasive cyprinids (e.g., Carassius gibelio ; Tarkan et al, 2023), also attributed to local environmental conditions.…”

The topmouth gudgeon Pseudorasbora parva is one of the worst invasive species worldwide and is considered to be highly plastic in terms of its phenotype but also behavioral ecology. Here, we analyzed the population structure and the morphological and dietary plasticity of four populations of P. parva across the four seasons within the Arno River basin in Central Italy. We found that the studied populations were morphologically different, suggesting multiple introductions or adaptation to different environmental conditions. In all populations, males were bigger and, overall, more frequent than females. The gonadosomatic index showed a similar pattern across all populations, with higher spring and summer values, indicating a long reproductive period. The diet of P. parva considerably varied across populations and seasons, suggesting a high degree of spatio-temporal trophic plasticity. Diet breadth varied among seasons, being more specialized in spring and summer and more opportunistic during autumn and winter. Our results highlight high trophic plasticity in the invasive populations of P. parva, potentially impacting multiple native taxa.

“…However, not all newcomers impose such changes, therefore, it is important to determine the traits that predict them to become successful invaders. Thus the analyses of life-history traits and morphology represent the best source of information (Feiner et al 2012, Záhorská et al 2013b, 2017, Jia et al 2019). Successful invasive species can modify their life history strategies to adapt to new areas, or they will be excluded/replaced.…”

Biological invasions are part of processes connected with human activities, which threaten biodiversity and all ecosystems, including freshwaters. Many research studies aim to discover the main traits responsible for invasive success. The topmouth gudgeon is one of the most successful invasive fish species; thus, this study aimed to analyse morphological variability and sexual dimorphism of two topmouth gudgeon populations coming from different sites in Bulgaria (n = 150 in both cases) and to evaluate its morphological variability in connection to differently disturbed habitats of occurrence. For this, we measured thirty morphometric characters, which were subsequently statistically analysed. The species is characterised by high morphological variability between the populations from different sites and also within populations. We showed that populations from Bulgaria differed mainly in traits connected with specific body dimensions. The population from the Kolarovo channel showed a significantly deeper head, bigger mouth and longer body in the front part. On the other hand, the population from Lake Zafirovo had a significantly longer caudal peduncle and caudal and anal fins. Differences between males and females were found between traits connected to the head and fins, which made males more robust with longer fins. At the same time, females were characterised by deeper bodies, which is essential for their investment in reproduction.

“…Over time, these fishes evolved from primitive Barbinae into three distinct classes (i.e., primitive, specialized, and highly specialized) to adapt to the elevation‐related environmental changes resulting from the uplift of the Tibetan Plateau (Cao et al., 1981). Schizothoracine fishes have been evaluated as the most threatened freshwater fish group across China (Cao et al., 2016; Chen et al., 2023), primarily due to widespread anthropogenic disturbances such as climate change, hydropower development, and biological invasion (Jia et al., 2019; Tao, Ding, et al., 2023; Wang et al., 2023; Zhang et al., 2019).…”

Understanding environmental requirements for fish reproduction in natural habitats is crucial for population conservation and restoration. However, such information is extremely scarce for the highly threatened schizothoracine fishes that cover large elevation ranges on the Tibetan Plateau. This research investigated the spawning time, output and environmental conditions of wild Schizopygopsis thermalis along an elevational gradient (i.e., from 1766 to 4372 m) in the upper Nu‐Salween River. It found that the spawning grounds of S. thermalis were mainly located at elevations between 3600 and 4372 m, and spawning habitats mostly consist of still marginal areas (still water <10 cm deep) with gravel substrates. Otolith microstructure analysis revealed, for the first time, that S. thermalis spawns in two seasons (i.e., winter: from December to next February, and spring: from April to May), with the winter spawning period generally longer than the spring spawning period. Winter spawning started earlier and ended earlier at higher elevations, while spring spawning occurred earlier at lower elevations but ended simultaneously at higher elevations. As elevation increases, reproductive output also increases, and spawning cohorts shift from winter‐dominant to spring‐dominant. Winter spawning cohorts were associated with lower water temperatures but higher discharges than the spring spawning cohort, and both cohorts showed elevation‐related environmental preferences. Our results suggest that schizothoracine fish can adapt spawning strategies to elevation‐related environmental conditions, which fill the gaps in the reproductive characteristics of schizothoracine fishes, and highlight the importance of conserving schizothoracine habitats at high elevations in the Qinghai‐Tibetan rivers.
