Intensification of open-ocean oxygen depletion by vertically migrating animals
Throughout the ocean, countless small animals swim to depth in the daytime, presumably to seek refuge from large predators1,2. These animals return to the surface at night to feed1,2. This substantial diel vertical migration can result in the transfer of significant amounts of carbon and nutrients from the surface to depth3–7. However, its consequences on ocean chemistry at the global scale hav...
متن کاملBordetella bronchiseptica responses to physiological reactive nitrogen and oxygen stresses.
Bordetella bronchiseptica can establish prolonged airway infection consistent with a highly developed ability to evade mammalian host immune responses. Upon initial interaction with the host upper respiratory tract mucosa, B. bronchiseptica are subjected to antimicrobial reactive nitrogen species (RNS) and reactive oxygen species (ROS), effector molecules of the innate immune system. However, t...
متن کاملPhysiological responses of intertidal marine brown algae to nitrogen deprivation and resupply of nitrate and ammonium.
Intertidal macroalgae Fucus and Laminaria experience seasonally fluctuating inorganic N supply. This study examined the effects of long-term N deprivation, recovery following N resupply, and effects of elevated ammonium and nitrate exposure on N acquisition in intertidal algae using manipulations of N supply in tank culture. Over 15 weeks of N deprivation, internal N and nitrate reductase activ...
متن کاملReactive oxygen species-dependent wound responses in animals and plants.
Animals and plants evolved sophisticated mechanisms that regulate their responses to mechanical injury. Wound response in animals mainly promotes wound healing processes, nerve cell regeneration, and immune system responses at the vicinity of the wound site. In contrast, wound response in plants is primarily directed at sealing the wound site via deposition of various compounds and generating s...
متن کاملPhysiological, behavioral and biochemical adaptations of intertidal fishes to hypoxia.
Hypoxia survival in fish requires a well-coordinated response to either secure more O(2) from the hypoxic environment or to limit the metabolic consequences of an O(2) restriction at the mitochondria. Although there is a considerable amount of information available on the physiological, behavioral, biochemical and molecular responses of fish to hypoxia, very little research has attempted to det...
