Tributaries of the Colorado River Basin, historically home to a complex of endemic omnivores collectively referred to as the ‘three species’; flannelmouth sucker (Catostomus latipinnis), bluehead sucker (C. discobolus) and roundtail chub (Gila robusta), have experienced the establishment of numerous non-native fish species. In this study, we examine the impacts of the trophic ecology of non-nat...
Ancient mass extinction events such as the end-Permian and endTriassic crises provide analogues for multistressor global change of ocean warming, pH reduction, and deoxygenation. Organism physiology is hypothesized to be a key trait influencing vulnerability to these stressors, but it is not certain how physiology predicts survival over evolutionary time scales and when organisms are faced with...
Coral reef fishes are in general rather sedentary and territoriality and home range behavior patterns are highly developed. However, many species migrate, often relatively long distances compared to body size and often with spectacular precision. Migrations in reef fishes may be associated with: 1) life history-movements of planktonic larval stages to reefs or movements of juveniles from nurser...
Life-history traits of batoids (Superorder Batoidea) in the Northeast Atlantic and the Mediterranean
Abstract Life-history traits provide a way to estimate the vulnerability of both individuals and populations species disturbance (e.g., overexploitation, climate change). compilations for batoids in Northeast Atlantic (NEA) Mediterranean Sea (MED) are scarce, outdated, generally limited local or regional scale. A literature review compiling values 10 life-history describing growth, reproductive...
This review examines the neurobehavioral nature question of whether fishes are capable of experiencing pain and effects of anthropomorphic thinking and the importance of an e understanding the neurobehavioral differences between fishes differences in central nervous system structure that underlie ba between fishes and humans are described. The literature on th and of pain is reviewed, showing t...
Invertebrates can acquire functional genes via horizontal gene transfer (HGT) from bacteria but fishes are not known to do so. We provide the first reliable evidence of one HGT event from marine bacteria to fishes. The HGT appears to have occurred after emergence of the teleosts. The transferred gene is expressed and regulated developmentally. Its successful integration and expression may chang...
During a parasitological investigation on the fresh water fishes of North West of Iran (West Azerbaijan Province), 266 specimens of 11 fishes were examined. Fishes were collected from seven stations from Aras, Zangbar and Sarysou Rivers between summer 2001 to summer 2002. Nine protozoan species were detected; eight Cilliophora and one Rhizopoda. Cilliophora are: Chilodonella sp., Apiosoma sp.,V...
