“…A recently-established topmouth gudgeon in Northwest England grew faster than those longer established, which resembles patterns observed in other invasive fishes (i.e. increased juvenile growth and early maturation), such as pumpkinseed [20]. Britton et al [7] concluded that all these traits were advantageous in maximising early life reproduction in a new population, facilitating colonisation and establishment, a process already completed in the highdensity population.…”

Specimens of invasive topmouth gudgeon, Pseudorasbora parva, from Šúr Pond (Bratislava, Slovakia) were examined to assess age and growth, and to determine whether this recently-established invasive population employs a less specialized ontogenetic trajectory than the specialized form typical of native and/or long-time established populations. Samples were collected in October 2004 (n=143). Standard length (SL) ranged from 18.16 mm to 67.57 mm (mean 32.56 mm), and eviscerated body weight ranged from 0.10 to 5.02 g (mean 0.63 g). Scale caudal diameter ranged from 0.52 to 2.42 mm (mean 1.08 mm). SL at which the scales started to form was estimated to be 1.58 mm. The population was represented with 5 age groups, from 0+ to 4+. Relative to other populations for which comparable data are available the recently-established population of topmouth gudgeon was found to mature at smaller size and at a younger age compared to native and/or long-time established populations (all specimens bigger than 25.0 mm SL, and 94% of specimens from the age group I were already mature).© Versita Sp. z o.o.

“…In southern Europe, however, the species is also abundant in lotic waters (Godinho et al 1997;Gutiérrez-Estrada et al 2000). Copp and Fox (2007) and demonstrated that pumpkinseed invasiveness at lower latitudes may be attributed to warmer climatic conditions resulting in a higher fecundity (i.e. rapid maturation and faster juvenile growth).…”

Pumpkinseed sunfish (Lepomis gibbosus) invasions facilitated by introductions and nature management strongly reduce macroinvertebrate abundance in isolated water bodies

et al. 2008

The pumpkinseed sunfish, Lepomis gibbosus, originates from Eastern North America and was introduced to the Netherlands in 1902 as an aquarium and garden pond fish. At present the pumpkinseed is widely spread throughout the Netherlands and occurs in a variety of aquatic habitats. It is especially abundant in moorland pools, fishing ponds and urban waters. Strong population development of the pumpkinseed appears to be facilitated by nature management practices in existing ponds (the removal of accumulated organic matter and macrophytes) and by creating new ponds. These measures enhance suitable breeding habitats that are free of competitors and predators. Isolated waters harbouring pumpkinseed were more often situated close to human habitation and infrastructure than could be expected based on the distribution of randomly selected isolated waters, identifying introductions as an important dispersal mechanism. In order to minimize the chances of introductions, planning of nature management practices should be done at distances over 250 m from human habitation and 100 m from infrastructure. Macroinvertebrate abundance in pools populated by pumpkinseed was eighty three percent lower than in pools without pumpkinseed, probably due to opportunistic feeding and high pumpkinseed abundances. Currently there is little experience with pumpkinseed control. However, options to be explored include: decreasing depth of colonized waters by filling them with soil allowing them to occasionally dry up, introducing native competitors and predators and the use of biodegradable piscicides. In addition, limitation of the sale of pumpkinseed is required as well as public education on the consequences of introducing exotic species.

“…Within the context of the theory of alternative ontogenies and invasive potential, the values of absolute number of oocytes and relative fecundity are more important than those of real absolute fecundity. This is because this theory assumes that individuals from a population exposed to frequent disturbances develop into the generalized phenotypes that tend to increase their production of offspring, not only diverting allocation of their sources towards reproduction rather than somatic growth (Copp and Fox, 2007) but also redistributing them into a higher number of offspring (Balon, 2004). However, what is finally the real number of successfully spawned oocytes depends on particular local conditions during the particular spawning season.…”

Key-words:round goby, biological invasions, epigenesis, alternative ontogenies, reproductive parametersOne of the most successful invasive fish species with negative impacts is round goby Neogobius melanostomus that has spread from its original Ponto-Caspian area to west and central Europe and even to North America. Previous studies focused on invasive fishes have revealed that these species have the capability to generate forms with life-history traits that differ between native and non-native populations. As a contribution to explain their invasion success, the theory of alternative ontogenies and invasive potential has been developed. The main aim of the present study was to test the hypothesis derived from this theory, which predicts that females of the non-native population of N. melanostomus (from Slovakia) will have significantly smaller oocytes, higher fecundity and smaller body size at maturity than those of the native population (from Bulgaria). All the three quantitative parameters of life-history traits examined in this study were found to be consistent with the predictions tested. Variations in reproductive parameters observed in non-native N. melanostomus demonstrate the species' phenotypic plasticity, which appears to be an important attribute that helps potential invaders to establish new populations in unknown environments. However, further experimental studies are necessary to verify this theory by testing hypotheses derived from it. Une des espèces les plus envahissantes de poissons aux impacts négatifs est le gobie à taches noires Neogobius melanostomus qui s'est propagé à partir de sa zone ponto-caspienne native vers l'ouest et le centre de l'Europe et même en Amérique du Nord. Des études antérieures sur les poissons invasifs ont révélé que ces espèces ont la capacité de générer des individus avec des traits d'histoire de vie qui diffèrent entre les populations autochtones et non autochtones. En guise de contribution à expliquer leur succès d'invasion, la théorie des ontogenèses alternatives et du potentiel invasif a été développée. L'objectif principal de cette étude était de tester l'hypothèse dérivée de cette théorie, qui prédit que les femelles de la population non autochtone de N. melanostomus (de Slovaquie) auront de plus petits ovocytes, une plus forte fécondité et une plus petite taille à maturité que celles de la population autochtone (de Bulgarie). Tous les trois paramètres quantitatifs des traits d'histoire de vie examinés dans cette étude ont été jugés conformes aux prédictions testées. Les variations dans les paramètres de reproduction observés chez N. melanostomus non indigènes démontrent la plasticité phénotypique de l'espèce, qui semble être un attribut important qui aide les envahisseurs potentiels à établir de nouvelles populations dans des environnements inconnus. Toutefois, d'autres études expérimentales sont nécessaires pour vérifier cette théorie en testant des hypothèses qui en découlent. RÉSUMÉ
