Coral Adaptation and Acclimatization: A Most Ingenious Paradox

Biological Adaptation: Aptitudes and Acclimatization

[Hemoglobin and testosterone: importance on high altitude acclimatization and adaptation].

The different types of response mechanisms that the organism uses when exposed to hypoxia include accommodation, acclimatization and adaptation. Accommodation is the initial response to acute exposure to high altitude hypoxia and is characterized by an increase in ventilation and heart rate. Acclimatization is observed in individuals temporarily exposed to high altitude, and to some extent, it ...

Mesophotic coral depth acclimatization is a function of host-specific symbiont physiology

Reduced calcification and lack of acclimatization by coral colonies growing in areas of persistent natural acidification.

As the surface ocean equilibrates with rising atmospheric CO2, the pH of surface seawater is decreasing with potentially negative impacts on coral calcification. A critical question is whether corals will be able to adapt or acclimate to these changes in seawater chemistry. We use high precision CT scanning of skeletal cores of Porites astreoides, an important Caribbean reef-building coral, to ...

Paradox and Relativism

Since the time of Plato, relativism has been attacked as a self-refuting theory. Today, there are two basic kinds of argument that are used to show that global relativism is logically incoherent: first, a direct descendent of the argument Plato uses against Protagoras, called the peritrope; and, second, a more recent argument that relativism leads to an infinite regress. Although some relativis...
