Summary
Research on carbonic anhydrase (CA) in sharks and rays is limited. Future studies should focus on non-lethal methods and climate change impacts on these vulnerable species.
Area of Science:
- Marine Biology
- Biochemistry
- Physiology
Background:
- Carbonic anhydrase (CA) is vital for acid-base balance, gas exchange, and osmoregulation in bony fishes.
- Research on CA functions in elasmobranchs (sharks and rays) remains limited.
- Existing studies show a decline in CA research over time.
Purpose of the Study:
- To review the current state of carbonic anhydrase research in sharks and rays.
- To identify knowledge gaps and future research needs.
- To guide future studies on CA in elasmobranchs, considering conservation and climate change.
Main Methods:
- Literature review of existing studies on carbonic anhydrase in elasmobranchs.
- Analysis of research trends, differentiating historical and recent approaches.
- Identification of key research areas, including physiological roles and climate change effects.
Main Results:
- A decreasing trend in publications on CA in elasmobranchs was observed.
- Early research focused on basic CA functions, while recent studies adopt comparative and interdisciplinary approaches (ecology, phylogeny).
- Climate change effects on CA are identified as a critical area for future investigation.
Conclusions:
- There is a need to expand CA research in elasmobranchs, particularly focusing on conservation.
- Future studies should prioritize non-lethal methodologies.
- Investigating the impact of climate change on CA is crucial for elasmobranch species response and survival strategies.

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

01:57Adaptations that Reduce Water Loss
25.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

00:59Tonicity in Animals
118.0K
The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

01:50Global Climate Change
24.6K
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.

01:25Regulation of Water Intake
594
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...
