Studying the Relationship Between Morphological Characteristics and Ecological Niche Overlap of the Namak Chub (Squalius namak) In the Jajroud River [PDF]

محیط زیست و توسعه فرابخشی
Introduction: The degree of overlap in ecological niches can indicate the extent of resource sharing and potential interspecific competition. The intensity or effects of resource sharing and competition may also be partially related to species abundance,

SchussenAktivplus: reduction of micropollutants and of potentially pathogenic bacteria for further water quality improvement of the river Schussen, a tributary of Lake Constance, Germany [PDF]

, 2013
The project focuses on the efficiency of combined technologies to reduce the release of micropollutants and bacteria into surface waters via sewage treatment plants of different size and via stormwater overflow basins of different types. As a model river

Effects of LPXRFamide peptides on chub mackerel gonadotropin secretion

Biology of Reproduction, 2021
AbstractGonadotropin-inhibitory hormone (GnIH), a neuropeptide, suppresses gonadotropin (GTH) secretion in birds and mammals. In fish, the GnIH homolog LPXRFamide (LPXRFa) produces mature peptides with species-dependent effects on sexual reproduction.

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Age and growth rates of a translocated chub Squalius cephalus chalk-stream population with comparison to indigenous riverine populations in England

Knowledge and Management of Aquatic Ecosystems, 2022
Introduced fishes into lowland rivers can result in invasive populations establishing and then dispersing, where knowledge of their life history traits contributes to understandings of their invasion ecology.

Plasticity in the reproductive biology of Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake following lake trout Salvelinus namaycush invasion

Journal of Fish Biology, EarlyView.
Abstract Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake are the focus of intensive conservation efforts due to the threat of predation by invasive lake trout Salvelinus namaycush. Suppression gillnetting has reduced the abundance of predatory lake trout, and the Yellowstone cutthroat trout population is recovering ...
