A Practical Guide to the Developmental Biology of Terrestrial-Breeding Frogs
The Biological Bulletin
|January 10, 2018
Summary
Many frogs reproduce on land, laying large eggs with unique developmental patterns. This study offers practical methods for studying terrestrial frog embryos, aiding research into developmental evolution.
Area of Science:
- Developmental Biology
- Evolutionary Biology
- Amphibian Research
Background:
- Most frog reproduction occurs in water, with well-documented larval development.
- A significant number of frog species exhibit terrestrial reproduction, characterized by large eggs and modified developmental pathways.
- Examples include direct development in Eleutherodactylus coqui and pouch brooding in Gastrotheca riobambae.
Purpose of the Study:
- To provide practical methodologies for researchers studying terrestrial frog development.
- To facilitate access to terrestrial-breeding frog species for scientific investigation.
- To support research on the developmental and evolutionary implications of terrestrial reproduction in amphibians.
Main Methods:
- Guidance on obtaining eggs and embryos from terrestrial-breeding frog species.
- Protocols for analyzing the early development of these embryos.
- Focus on species like Gastrotheca riobambae and Eleutherodactylus coqui.
Main Results:
- Established practical protocols for accessing and studying terrestrial frog embryos.
- Demonstrated feasibility of analyzing unique developmental patterns in species with direct development or pouch brooding.
- Provided a foundation for comparative studies on amphibian reproductive strategies.
Conclusions:
- Terrestrial frog development presents unique research opportunities.
- Standardized methods can enhance accessibility and comparability in studying these species.
- This work supports broader investigations into the evolution of development in amphibians.

01:27Introduction to Developmental Psychology
1.7K
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

01:14Design Example: Frog Muscle Response
618
A student is tasked to work on an intriguing experiment involving an RL (Resistor-Inductor) circuit to study the muscle response of a frog's leg to electrical stimulation. The RL circuit plays a crucial role in this experiment, providing the means to control and measure the electrical impulses that trigger muscle contraction.
When the switch connecting the RL circuit is closed, a brief muscle contraction is observed. This is because, at a steady state, the inductor acts like a short...

18.1K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
