Form and Function of Crickets and Crayfish ExpandNOTE: To observe the relationship between form and function in animals, you will be examining and dissecting a cricket and a crayfish. Each pair of students will receive one of each of these organisms. When dissecting, be sure to wear gloves, closed-toed shoes, and safety goggles. Take care when handling dissecting tools, as they may be sharp. HYPOTHESES: In this experiment, the experimental hypothesis could be that the cricket and crayfish have...

New Variations for Strategy Set-shifting in the Rat

Set-shifting, a form of behavioral flexibility, requires an attentional shift from one stimulus dimension to another. We extended an established rodent set-shifting task1 by requiring attention to different stimuli according to context. The task was combined with specific lesions to identify neuron subtypes underlying a successful shift.

X-ray Dose Reduction through Adaptive Exposure in Fluoroscopic Imaging

We are developing a dynamic adaptive exposure technique using our scanning beam digital X-ray system. Rather than exposing an object uniformly, the exposure is adapted depending on the opacity of the object. Here we show an experiment on an anthropomorphic phantom that resulted in a dose saving of 30%.

A Molecular Readout of Long-term Olfactory Adaptation in C. elegans

Here we describe a molecular readout of long-term olfactory adaptation in Caenorhabditis elegans. The Protein Kinase G, EGL-4, is necessary for stable adaptation responses in the primary sensory neuron pair called AWC. During prolonged odor exposure EGL-4 translocates from the cytosol to nucleus of the AWC.

FAQs
Natural selection changes the frequency of inherited variations within populations. When a trait improves an animal’s ability to survive or reproduce in a particular environment, individuals carrying that variation can contribute more offspring, making the trait more common over generations. This process links environmental conditions with changes in anatomy, physiology, or behavior across evolutionary time.
Adaptations are shaped by the demands of particular surroundings. Camouflage, temperature regulation, feeding, movement, and predator avoidance may become especially important in different habitats, so traits that improve performance in one setting may not provide the same advantage elsewhere. Examining these differences helps biologists explain how animals occupy diverse habitats and maintain ecological roles.
Heritable traits can be passed between generations and become more common through natural selection, whereas behavioral flexibility allows an individual to respond to changing conditions during its lifetime. These mechanisms operate on different timescales but can both support survival and reproduction. Distinguishing them helps researchers interpret whether an observed response reflects evolutionary change or immediate behavioral adjustment.
These biological levels provide complementary evidence about how animals function in their environments. Anatomy concerns structures, physiology concerns internal functions, behavior concerns actions, and ecology concerns relationships with habitats and other organisms. Considering them together shows how a trait or response contributes to survival and reproduction rather than treating adaptation as an isolated feature.
A study can relate an animal’s trait or behavior to environmental conditions and then examine its contribution to functions such as feeding, movement, temperature regulation, or predator avoidance. Researchers can also consider whether the characteristic is heritable, behaviorally flexible, or associated with reproduction and survival. This approach connects observations to evolutionary and ecological interpretation.
Adaptation research helps identify how animals may respond when habitats change or environmental conditions shift. Understanding the traits and behaviors linked to survival and reproduction can clarify species resilience, while comparing habitat requirements can reveal potential conservation concerns. These insights support efforts to protect biodiversity and anticipate biological responses to climate change and habitat disturbance.
