Surveys

16.6K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Introduction to Surveying, Plane Surveying and Geodetic Surveys

1.0K
Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Social Traps

26.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Types of Surveys

354
Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Survey Safety01:28

Survey Safety

374
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Errors and Mistakes in Surveying01:19

Errors and Mistakes in Surveying

642
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...

Summary
This summary is machine-generated.

Enhancing camera-trap methods for squamate (snake and lizard) surveys significantly improves detection rates. Adjusting programming to include time lapse and passive infrared sensor (PIR) triggering, alongside closer focal lengths, yields better quantity and quality of images.

Area of Science:

  • Wildlife ecology
  • Herpetology
  • Conservation technology

Background:

  • Camera-traps are widely used for vertebrate fauna surveys, including mammals, birds, and reptiles (squamates).
  • Reliability of camera-traps for censusing squamates can be improved through optimized settings and hardware.
  • Limited data exists on effective camera-trapping strategies specifically for snakes and lizards.

Purpose of the Study:

  • To evaluate the effectiveness of time lapse capture settings in improving squamate detections using camera-traps.
  • To compare detection rates between standard passive infrared sensor (PIR) triggering and time lapse modes.
  • To assess the impact of camera trap focal length on species discrimination for small squamates.

Main Methods:

  • Conducted side-by-side field comparisons of camera-traps with different programming options: PIR only, time lapse only, and combined time lapse with PIR.
  • Examined camera-traps set at varying focal lengths to determine their effect on species identification.
  • Quantified and compared the number and quality of squamate images captured under different settings.

Main Results:

  • Camera-traps programmed with combined time lapse and PIR triggering captured significantly more squamate images than PIR or time lapse alone.
  • Setting camera traps with a closer focal length improved the ability to discriminate between different species of small squamates.
  • Minor adjustments in camera-trap programming and hardware led to marked improvements in both the quantity and quality of squamate detections.

Conclusions:

  • Optimized camera-trap settings (combined time lapse and PIR) enhance the reliability of squamate surveys.
  • Utilizing closer focal lengths improves species identification accuracy for small squamates.
  • These methodological advancements offer a foundation for future research and improved knowledge of poorly studied squamate populations.
