BACKGROUND In ectothermal animals such as fish, -temperature affects physiological and metabolic processes. This includes sensory organs such as the auditory system. The reported effects of temperature on hearing in eurythermal otophysines are contradictory. We therefore investigated the effect on the auditory system in species representing two different orders. METHODOLOGY/PRINCIPAL FINDINGS...

Relationships between fish length and otolith length, width mass were investigated in the two nearly threatened silurid species (Siluriformes) Ailia coila (Hamilton, 1822) Ompok pabda Hamilton, collected from Ganga River at Narora, India. The relationships (OL) total (TL), (OWd) TL, weight (OWe) TL are expressed by linear regression models; for A. coila, OL = 0.0291 + 0.8541, OWd 0.0306 0.2241,...

We report the presence of the parasitic copepod Ergasilus mosulensis Rahemo, 1982 (Copepoda, Ergasilidae) on the Caspian sheaya, Chalcalburnus mossulensis (Heckel, 1843) (Teleostei, Cyprinidae), caught from Atatürk Dam Lake (360 41' N 370 49' E, Sanliurfa, Turkey) between July and August 2006. A total of 23 Ergasilus mosulensis Rahemo, 1982 (Ergasilidae) were recorded from the gills of this fis...

Achieving conservation and natural resource management goals requires changes in human behaviour, which involves understanding perspectives how people might adopt new values, approaches or practices (Nielsen et al., 2021; Stankey & Shindler, 2006; Stoll-Kleemann, 2019). Successful outcomes may depend identifying viewpoint ar...
