Breadth versus depth of knowledge: the need for new model trematode species

Area of Science:

• Parasitology
• Ecology
• Evolutionary Biology

Background:

• Scientific progress involves a trade-off between knowledge breadth (discovering many species) and depth (detailed study of few species).
• Parasitology currently prioritizes breadth, with a high rate of new trematode species discovery.
• Achieving comprehensive understanding requires balancing both breadth and depth.

Purpose of the Study:

• To assess the current balance between knowledge breadth and depth in trematode research.
• To propose a strategy for increasing the depth of understanding in parasitology.
• To demonstrate the feasibility of developing model trematode species for in-depth study.

Main Methods:

• Analysis of current research trends in trematode biodiversity and taxonomy.
• Case study on developing novel model trematode species.
• Evaluation of the potential of model species for studying ecological dynamics, co-evolution, and environmental responses.

Main Results:

• Trematode research is rapidly increasing knowledge breadth but not depth at a comparable rate.
• Model species, despite caveats, present a viable strategy for deepening parasitological knowledge.
• A case study illustrates low-cost development of model trematodes for enhanced understanding.

Conclusions:

• Parasitology needs to prioritize depth of knowledge alongside breadth.
• Developing model trematode species can significantly enhance understanding of host-parasite interactions and evolutionary processes.
• A call to action for parasitologists to invest more effort in deepening knowledge through focused research.
