Interactions of invasive pumpkinseed with a riverine endemic fish indicate trophic overlap but minimal consequences for somatic growth and condition
Karakuş, Uǧur; Tarkan, Ali Serhan; Yalçın-Özdilek, Şükran; Top-Karakuş, Nildeniz; Partal, Nurbanu; Britton, John Robert (EDP Sciences, 2023)The North American invasive fish pumpkinseed Lepomis gibbosus has been associated with some detrimental ecological consequences in some parts of its invasive range. Here, we tested the trophic interactions of pumpkinseed ... -
Invasion of pumpkinseed Lepomis gibbosus is facilitated by phenotypic plasticity across its invasion gradient
Tarkan, Ali Serhan; Karakuş, Uğur; Top Karakuş, Nildeniz; Keskin, Emre; Ünal, Esra Mine; Britton, John Robert (Springer, 2021)As a non-native species invades a new region, individuals at the range front are often characterised by differences in their traits and behaviours versus individuals in the established ‘core’ area. Here, differences in ... -
Life history characteristics of the potentially invasive Ponto-Caspian goby Neogobius fluviatilis in natural lakes from its native range (Black Sea region of Turkey)
Karakuş, Uğur; Top, Nildeniz; Tepekoy, Erdi Gökhan; Britton, John Robert; Tarkan, Ali Serhan (Csiro Publishing, 2018)The aim of this study was to provide baseline data and fill an outstanding knowledge gap in our understanding of factors affecting the invasiveness of the Ponto-Caspian gobiid Neogobius fluviatilis. To this end, the life ... -
Native drivers of fish life history traits are lost during the invasion process
Gozlan, Rodolphe Elie; Zahorska, Eva; Cherif, Emira; Asaeda, Takashi; Britton, John Robert; Chang, Cha-Ho; Combe, Marine (Wiley, 2020)Rapid adaptation to global change can counter vulnerability of species to population declines and extinction. Theoretically, under such circumstances both genetic variation and phenotypic plasticity can maintain population ... -
Plasticity in habitat use of two native Ponto-Caspian gobies, Proterorhinus semilunaris and Neogobius fluviatilis: implications for invasive populations
Top, Nildeniz; Karakuş, Uğur; Tepeköy, Erdi Gökhan; Britton, John Robert; Tarkan, Ali Serhan (Edp Sciences S A, 2019)The Ponto-Caspian region is an important source area for some invasive gobiid fishes. These fishes have colonised several freshwater ecosystems in Europe, as well as in North America. As knowledge on their habitat utilisation ... -
Plasticity in life history traits of the native Proterorhinus semilunaris suggests high adaptive capacity in its invasive range
Top, Nildeniz; Karakus, Ugur; Tepekoy, Erdi Gokhan; Britton, John Robert; Tarkan, Ali Serhan (Edp Sciences S A, 2018)Invasion risk assessments are reliant on ecological data that assist the predictions of whether an introduced species will adapt to novel conditions. Data from the native range of potential invaders can thus assist these ... -
Trophic Interactions of Two Ponto-Caspian Gobies in the Turkish Part of Their Native Range
Tarkan, Ali Serhan; Karakus, Ugur; Tepekoy, Erdi Gokhan; Top, Nildeniz; Ozdilek, Sukran Yalcin; Partal, Nurbanu; Britton, John Robert (Central Fisheries Research Inst, 2018)Several Ponto-Caspian gobiids have expanded from their native distribution ranges to Europe and North America. As knowledge on their bio-ecological features in their native range is still limited, the trophic ecology of ...
