The effect of temperature on haemoglobin–oxygen binding affinity in regionally endothermic and ectothermic sharks
The effect of temperature on haemoglobin–oxygen binding affinity in regionally endothermic and ectothermic sharks Phillip R. Morrison, Diego Bernal, Chugey A. Sepulveda, Colin J. Brauner ABSTRACT: Haemoglobin (Hb)–O2 binding affinity typically decreases with increasing temperature, but several species of ectothermic and regionally endothermic fishes exhibit reduced Hb thermal sensitivity. Regionally endothermic sharks, including the common
Recreational fishery discard practices influence use of tidal estuary by a large marine mesopredator
Recreational fishery discard practices influence use of tidal estuary by a large marine mesopredator Joni Pini-Fitzsimmons, Nathan A. Knott, Culum Brown ABSTRACT: Context: It is common for recreational anglers to discard waste produced from filleting catches back into the water, which results in a highly spatio-temporally predictable food subsidy for wildlife to scavenge. However, the
