Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Responses to Heat and Cold Stress

14.0K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

What is Climate?01:16

What is Climate?

19.3K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Transcription01:10

Transcription

150.0K
Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
Transcription Can Produce Different Kinds...

Temperature Dependent Deformation01:12

Temperature Dependent Deformation

207
In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

39.5K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Area of Science:

  • Ecology
  • Climate Change Biology
  • Entomology

Background:

  • Phenological shifts in insects vary due to differential exposure and sensitivity to climate change.
  • Environmental gradients (elevation, latitude) can influence insect temperature sensitivity and phenological responses.
  • Linking insect developmental traits to phenology and fitness is crucial for understanding climate change impacts.

Purpose of the Study:

  • To examine the phenological implications of variation in insect developmental traits.
  • To connect environmental sensitivity of insect development to phenology and fitness.
  • To understand variable phenological responses to climate change and their community/ecosystem consequences.

Main Methods:

  • Examining phenological shifts in insect species across different locations.
  • Analyzing variations in developmental traits in response to environmental conditions.
  • Coupling physiological and ecological insights to link development, phenology, and fitness.

Main Results:

  • Phenological shifts are not uniform across insect species and environments.
  • Developmental traits influence temperature sensitivity and lead to differential phenological shifts.
  • Controlled experiments require validation in realistic, temporally variable natural environments.

Conclusions:

  • Understanding insect developmental variation is essential for predicting climate change impacts.
  • Bridging lab and field studies is necessary to accurately assess phenological responses.
  • Anticipating climate change effects on insects requires robust linkages between development and phenology.
