Summary
Temporal road closures at night significantly increased wildlife detection on roads in Banff National Park. This conservation strategy enhances wildlife habitat quality while allowing for continued human use.
Area of Science:
- Wildlife ecology
- Conservation biology
- Road ecology
Background:
- Human activities increasingly threaten wildlife populations.
- Area closures can benefit wildlife but conflict with economic priorities like tourism.
- Temporal closures offer a potential solution by limiting human access during specific times.
Purpose of the Study:
- To assess the effectiveness of a daily temporal road closure on wildlife movements.
- To determine if temporal closures improve habitat quality for wildlife.
- To evaluate this conservation tool in Banff National Park.
Main Methods:
- Implemented a temporal road closure (20:00–08:00) on a 17 km stretch.
- Monitored nine mammal species using remote cameras and road surveys.
- Analyzed grizzly bear (Ursus arctos) GPS data.
Main Results:
- Wildlife detection rates on the closed road doubled during closure hours.
- Detection rates remained unchanged in comparable reference areas.
- Consistent results across camera, survey, and GPS data.
Conclusions:
- Temporal road closures are an effective conservation tool for increasing wildlife habitat quality.
- This method balances wildlife needs with human access and economic drivers.
- Supports the use of temporal closures in protected area management.

02:31Habitat Fragmentation
21.3K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

01:17Design Example: Alignment of a Road Line Using GIS
345
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

01:28Angle Closure Glaucoma: Treatment
1.2K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:19Quality of Water
553
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

01:05Quality Control
1.9K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

01:19Quality Assurance
1.6K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
