Trophic niche overlap between native and non‐native fishes in central Anatolian lakes, Türkiye

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Central Anatolian region of Türkiye exhibits exceptionally high freshwater fish diversity and endemism and is increasingly exposed to the introduction of non‐native taxa. We examined the diet composition, prey selectivity and interspecific dietary overlap among eight native and five non‐native fish species across seven lakes in Central ...

Plasma 24S-hydroxycholesterol (cerebrosterol) is increased in Alzheimer and vascular demented patients

open access: yesJournal of Lipid Research, 2000
Alzheimer's disease (AD) is characterized by the presence of senile plaques, neurofibrillary tangles, and neuronal cell loss associated with membrane cholesterol release.

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

open access: yesJournal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

Effects of Large-Scale Releases on the Genetic Structure of Red Sea Bream (Pagrus major, Temminck et Schlegel) Populations in Japan.

open access: yesPLoS ONE, 2015
Large-scale hatchery releases are carried out for many marine fish species worldwide; nevertheless, the long-term effects of this practice on the genetic structure of natural populations remains unclear.

Vestibular effects on cerebral blood flow

open access: yesBMC Neuroscience, 2009
Background Humans demonstrate a number of unique adaptations that allow for the maintenance of blood pressure and brain blood flow when upright. While several physiological systems, including cerebral autoregulation, are involved in this adaptation the ...

Sex‐dependent divergence in river use following maturation in Japanese seabass Lateolabrax japonicus revealed by otolith Sr:Ca chronologies

open access: yesJournal of Fish Biology, EarlyView.
Abstract Partial migration, in which migratory and resident individuals coexist within a population, is widespread in fishes and contributes to population resilience. However, the role of sex in shaping migratory strategies remains poorly understood. Herein, we examined partial migration in Japanese seabass Lateolabrax japonicus using sex ratios and ...

The enigmatic mitochondrial genome of Rhabdopleura compacta (Pterobranchia) reveals insights into selection of an efficient tRNA system and supports monophyly of Ambulacraria

open access: yesBMC Evolutionary Biology, 2011
Background The Hemichordata comprises solitary-living Enteropneusta and colonial-living Pterobranchia, sharing morphological features with both Chordata and Echinodermata.
