Genetic Drift03:33

Genetic Drift

41.3K
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

Distance Corrections01:15

Distance Corrections

109
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Adjusting a Traverse01:12

Adjusting a Traverse

146
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

Instinctive Drift01:05

Instinctive Drift

367
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Relative Motion Analysis using Rotating Axes-Problem Solving

472
Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

Common Leveling Mistakes and Errors01:17

Common Leveling Mistakes and Errors

158
A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...

Area of Science:

  • Ecology
  • Animal Movement Ecology
  • Biologging Technology

Background:

  • Accurate animal space-use estimation is crucial for ecological research but challenging.
  • Traditional radio telemetry (including GPS) uses Verified Positions (VPs), limiting path and distance accuracy due to temporal/spatial resolution.
  • Dead-reckoning offers improved path accuracy and resolution while conserving battery life, but optimal correction frequency remains unclear.

Purpose of the Study:

  • To review the utility of dead-reckoning for reconstructing animal movement paths.
  • To evaluate dead-reckoning error relative to Verified Positions (VPs) based on correction rates.
  • To assess the impact of dead-reckoning on distance traveled estimates and propose advancements.

Main Methods:

  • Reviewed dead-reckoning utility across four diverse species: African lion, red-tailed tropicbird, Magellanic penguin, and imperial cormorant.
  • Conducted simulations to quantify dead-reckoning error as a function of Verified Position (VP) correction rate.
  • Analyzed sources of measurement error in VP-corrected dead-reckoned tracks.

Main Results:

  • Dead-reckoning error was greatest for animals moving in air and water.
  • Simulations revealed the extent of dead-reckoning error relative to VPs based on VP correction rate.
  • Identified sources of measurement error in VP-corrected tracks and proposed methods to enhance accuracy.

Conclusions:

  • VP-corrected dead-reckoning is valuable for various movement types and ecological questions.
  • Dead-reckoning is particularly beneficial for studying animal-barrier interactions and foraging strategies.
  • Advancements in dead-reckoning procedures can maximize tracking accuracy for ecological research.
