Summary
Climate change impacts eukaryotic organisms, often ignoring microbial interactions. This review explores how environmental stress affects macroalgal holobionts, crucial for coastal ecosystems.
Area of Science:
- Marine Biology
- Microbial Ecology
- Climate Change Science
Background:
- Eukaryotic organisms and their associated microbes form holobionts, with microbes vital for host functions.
- Macroalgae are foundational to coastal ecosystems, relying on microbial symbionts for ecosystem services.
- The impact of environmental stress on macroalgal holobionts in a changing ocean remains poorly understood.
Purpose of the Study:
- To provide a conceptual framework for understanding holobiont-environment interactions under stress.
- To highlight the importance of microbial symbionts in macroalgal ecological roles.
- To propose experimental approaches for future research on macroalgal holobionts and climate change.
Main Methods:
- Conceptual review synthesizing current knowledge.
- Framework development for holobiont-environment interaction analysis.
- Proposal of manipulative experimental designs.
Main Results:
- Environmental stress can disrupt the mutualistic relationship within holobionts.
- Macroalgal holobionts are critical for maintaining coastal ecosystem functions.
- A lack of understanding exists regarding the specific effects of ocean change on these units.
Conclusions:
- Future research should focus on the interactive effects of environmental change on macroalgal holobionts.
- Manipulative experiments are essential to elucidate stress responses within the holobiont.
- Understanding holobiont dynamics is key to predicting coastal ecosystem resilience.

01:50Global Climate Change
28.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:22Effect of Sea Water on Concrete
1.0K
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.

01:17Work Done During Volume Change
5.1K
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

01:22Net Change Theorem
69
The Net Change Theorem is a fundamental principle in calculus that establishes a direct relationship between a function’s rate of change and its accumulated change over an interval. Mathematically, it states that the definite integral of a function's derivative over a given interval [a,b] yields the net change in the original function:This theorem has significant applications in various real-world scenarios, including physics, economics, and engineering. A particularly useful application...

Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in standard entropy between the products and the reactants.

02:19Le Chatelier's Principle: Changing Temperature
35.1K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:
