Predator-Prey Interactions02:39

Predator-Prey Interactions

22.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.5K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Types of Selection01:46

Types of Selection

46.2K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

8.5K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

10.9K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

What is Natural Selection?01:32

What is Natural Selection?

132.1K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Area of Science:

  • Evolutionary biology
  • Animal behavior
  • Sensory ecology

Background:

  • Ultraviolet (UV) light plays a role in animal vision, but its influence on amphibian larval development and behavior is not fully understood.
  • Developmental plasticity allows organisms to adjust their traits in response to environmental cues, potentially impacting sensory systems.

Purpose of the Study:

  • To investigate how developmental plasticity of UV visual sensitivity affects the predation efficiency of larval smooth newts (Lissotriton vulgaris).
  • To determine the role of UV light exposure during development and testing on visual sensitivity and foraging success.

Main Methods:

  • Quantified SWS1 opsin gene expression in newt retinas after development in UV+ and UV- conditions.
  • Assessed larval predation efficiency under both UV+ and UV- light conditions.
  • Correlated SWS1 opsin expression and predation success with developmental and testing light environments.

Main Results:

  • UV-reared larvae showed significantly reduced SWS1 opsin expression and lower predation efficiency.
  • Predation efficiency was consistently lower in a UV- testing environment, irrespective of developmental conditions.
  • A significant reduction in both SWS1 opsin expression and predation efficiency was observed in larvae developed in the absence of UV light.

Conclusions:

  • Demonstrated functional UV vision and developmental plasticity of UV sensitivity in larval amphibians for the first time.
  • UV wavelengths enhance predation efficiency in larval smooth newts.
  • The degree of behavioral adaptation to UV light is influenced by the developmental light environment and resulting retinal properties.
