Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.7K
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...

Osmoregulation in Fishes02:32

Osmoregulation in Fishes

50.5K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Global Climate Change01:50

Global Climate Change

24.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Responses to Salt Stress

13.4K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Responses to Heat and Cold Stress

13.9K
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?

19.0K
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.

Area of Science:

  • Aquatic Ecology
  • Climate Change Biology
  • Developmental Biology

Background:

  • Global climate change is increasing water temperatures, impacting fish development and survival.
  • The mechanosensory lateral line (LL) system is crucial for fish survival, but its development under thermal stress is unknown.

Purpose of the Study:

  • To investigate the effects of elevated water temperatures on the development of the lateral line system in brook trout (Salvelinus fontinalis).
  • To assess potential consequences for LL-mediated behaviors and survival in a changing climate.

Main Methods:

  • Brook trout were reared at ambient stream temperature and at +2°C and +4°C above ambient.
  • Key developmental transitions, growth, and lateral line canal morphogenesis were documented.

Main Results:

  • Elevated temperatures accelerated early life history transitions (hatch, swim-up) and increased parr-stage size.
  • Early canal neuromast organs were larger, and canal morphogenesis was accelerated at higher temperatures.

Conclusions:

  • Increased water temperatures alter brook trout development and LL system morphogenesis.
  • Accelerated development may lead to a mismatch between life history stages, LL function, and prey availability, impacting survival.
