Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, socio-economic interests. The stages successful are driven by same mechanism that underlies adaptive changes across species in general-via natural selection on intraspecific variation traits influence survival reproductive performance (i.e., fitness). Surprisingly, however, rapid progress field invasion science has resulted predominance species-level...
The zebra mussel Dreissena polymorpha is one of the most successful, notorious, and detrimental aquatic invasive non‐native species worldwide, having invaded Europe North America while causing substantial ecological socio‐economic impacts. Here, we investigated spatiotemporal trends in this species' invasion success using 178 macroinvertebrate abundance time series, containing 1451 records D. collected across nine European countries between 1972–2019. Using these raw (absolute) data,...
Introductions of non-native species can lead to severe impacts, including the decline ecosystem function through deleterious impacts on diversity. The successful establishment in new environments is first barrier a must overcome, ultimately depending its ability either cope with or adapt local site-specific conditions. Despite widespread distribution and ecological consequences many freshwater invaders, climatic preferences are often unknown, as case Eastern mosquitofish Gambusia holbrooki,...
Biological invasions are increasingly recognised as a major global change that erodes ecosystems, societal well-being, and economies. However, comprehensive analyses of their economic ramifications missing for most national economies, despite rapidly escalating costs globally. Türkiye is highly vulnerable to biological owing its extensive transport network trade connections well unique transcontinental position at the interface Europe Asia. This study presents first analysis reported caused...
Diplozoidae are common monogenean ectoparasites of cyprinoid fish, with the genus Paradiplozoon being most diversified. Despite recent studies on from Europe, Africa and Asia, diversity, distribution phylogeny this parasite group appears to be still underestimated in Middle East. The objective study was investigate endemism host specificity diplozoids parasitizing fish East, considering region as an important historical interchange fauna, elucidate phylogenetic position Eastern species...
Abstract The ability of fish to cope with warm water temperatures in summer depends on factors including their thermal traits and the individuals access cool-water refugia. Knowledge is highly limited situ responses many fishes elevated temperatures, whether they express behavioural thermoregulation. two riverine species were tested here using movement metrics, spatial habitat use body individual European barbel Barbus barbus (‘barbel’) common bream Abramis brama (‘bream’) versus river...
Rivers across the world are increasingly fragmented due to anthropogenic barriers, with restoration of connectivity often using fish passes. Fish passes are, however, usually designed for anadromous species, despite ecologically important non-anadromous species being present in communities impacted by fragmentation. To assess outcomes fishes installation multiple and weir modifications, movements potamodromous European barbel Barbus barbus were evaluated lower River Severn basin, western...
ABSTRACT Aims Clinostomid metacercariae infect a wide range of freshwater fish species, posing zoonotic risk to human health when consumed raw or undercooked, potentially leading Halzoun disease. Although these parasites are generally considered threat in Asian countries, they also present various regions Türkiye and have been found 12 different species commonly local cultures. However, their presence has not reported the endemic Anatolian fish, Alburnus escherichii . This study aims...
ABSTRACT The present study documents the first records of Oxynoemacheilus angorae and eregliensis in Göksu River within Mediterranean basin, which points to historical connectivity between Lake Beyşehir systems. Whereas O. is mainly distributed Western Black Sea, Marmara Lakes Region, , previously restricted Yeşildere region Central Anatolia Manavgat drainage southern Anatolia, was identified through morphological molecular analyses (COI barcode), confirming their taxonomic status. A review...
Sakarya River with a length of 824 km is one the most important lothic ecosystems Turkey. Sarıyar, Gökçekaya and Yenice Dams were constructed on Sararya for purpose electric supply utility water agricultural fishery activities. In this study, sediment samples collected from 14 stations selected areas seasonally (2015–2016). Also, cyprinidae species (Carassius gibelio (Bloch, 1782), Capoeta baliki Turan, Kottelat, Ekmekçi & Imamoglu 2006) caught Dam Lakes River. Cr, Ni, Cu, Zn, Pb levels in...
Abstract This study investigates the temporal and spatial distribution of species richness in Turkish portions Euphrates Tigris catchments Mesopotamia, aiming to identify areas lacking sufficient research inform future conservation management efforts. Data from 153 fish assemblages catchment 100 catchment, spanning 1941 2022, were analysed using a combination analytical occurrence, space‐for‐time mixed effect models. Results indicate an increase reported over time, attributed heightened...
Although the detrimental ecological and economic effects of introducing freshwater fish species have been extensively documented, non-native fishes continue to be introduced in large numbers globally enhance fisheries aquaculture. In Turkey, stocking common carp Cyprinus carpio is practised provide food security for people job artisanal fishers, resulting a country-wide distribution. These stockings, however, increase risk accidental introductions led subsequent invasions gibel Carassius...
Increased detrimental impacts of biological invasions have triggered the development risk screening tools to streamline identification invasive potential organisms. These assess and historical characteristics non-native species predict their invasiveness in a given geographical area. However, challenges for identifying such often require holistic approach, if more accurate predictions are needed. Here, case study is provided that combines molecular analysis (mtDNA barcoding) with (Aquatic...
Abstract Oxynoemacheilus fatmae , a new species, is found in the Güzelhisar Stream northern Aegean Sea basin. It differentiated from all other species of and adjacent basins by having four to eight irregularly shaped narrow black bars on posterior part flank, anterior parts flank with marbled pattern. O. closest theophilii 14 fixed diagnostic nucleotide substitution sites, pair‐wise genetic distance 2.22%. further differs slenderer body (body at dorsal‐fin origin: 15%–17% standard length...
The aim of this study was to report non-native tropical ornamental freshwater fish species from the PinarbaĹĽi Stream connected with hot-water sources in Inönü Province (EskiĹĽehir, Turkey). morphological characters and meristic counts indicated that examined specimens were: Pterygoplichthys disjunctivus (Weber, 1991), pardalis (Castelnau, 1855), their hybrids. We also present evidence reproduction establishment. Successful invasion these evident, as young-of-the-year juvenile...
Oxynoemacheilus sakaryaensis sp. nov. , is restricted to the Sakarya River basin, and O. melenicus distributed in both Büyükmelen Stream. distinguished by having a flank plain or with numerous irregularly shaped pale brownish bars caudal-peduncle depth 2.8–3.2 times its length. 10–13 irregular blotches caudal peduncle 1.9–2.8 banarescui samanticus simavicus fatsaensis are valid, which belong bergianus species group. were differentiated from all other western Anatolia two diagnostic unique...
Biological invasions, particularly of fish species, significantly threaten aquatic ecosystems. Among these invaders, the introduction European perch (Perca fluviatilis) can have detrimental effects on native communities, affecting both ecosystem functioning and human well-being. In this study, carbon nitrogen stable isotope analysis was employed, using originating from five different ecosystems, to model their hypothetical into İznik Lake, an economically ecologically important,...
The taxonomic status of native trout species the Marmara and Aegean Sea drainages is evaluated three species, Salmo duhani , S. coruhensis brunoi sp. nov. are recognized. a new described from Nilüfer River, tributary Susurluk River. It distinguished by general brownish body color in life; few black spots (fewer than 60) on body, generally scattered back upper part flank, rarely median part; 40) small (smaller pupil) red lower half flank; number not increasing with size both sexes; long...
