Data Collections
What is a method used to collect environmental data by capturing animals, marking them, and releasing them back into the population?
Capture-Mark-Recapture
What does "big data" refer to?
Data sets that are so large or complex that traditional data analysis methods are inadequate
What does GIS stand for?
Geographic Information Systems
What is crowdsourcing?
a way to gather information and ideas from a large group of people
What is random sampling?
A method where sample points are selected using random numbers to avoid bias
Name one advantage of using quadrat sampling in environmental studies.
Allows for the estimation of population density and species diversity
Name one benefit of analyzing big data in environmental management.
The ability to identify trends and patterns that inform policy decisions
How do GIS systems help in environmental management?
They organize, analyze, and visualize geospatial data for better decision-making
Name one example of a crowdsourcing tool used to address climate change.
Climate Crowd
Explain systematic sampling.
A method where sample points are selected according to a fixed, regular pattern
What is a disadvantage of using light traps in data collection?
May only attract specific species, potentially leading to biased results
What is one limitation of big data analysis?
The speed at which new data is generated can overwhelm traditional analysis methods
Describe one application of GIS in climate change studies
Mapping areas at risk of sea-level rise to plan for environmental adaptations
How does WWF utilize crowdsourcing?
To gather data on climate change and implement solutions through public participation
Describe the importance of representative sampling in environmental studies.
It ensures that the sample accurately reflects the diversity of the population being studied
Describe the beating tray technique used in ecological studies.
It involves shaking foliage over a tray to collect falling invertebrates for study
Explain how trustworthiness of data affects big data analysis.
Unreliable data can lead to incorrect conclusions and ineffective strategies
What was a major focus of environmental science approaches in the 1990s?
risk management and pollution monitoring
What is one challenge of using crowdsourcing in data collection?
The potential for bias in the data submitted by participants
What is point sampling?
Data collection done at a specific location rather than over an area
How does the Secchi Disk measure water transparency?
It is lowered into the water until it is no longer visible, with the depth recorded
Give an example of how big data can be used in public health.
Analyzing health trends across large populations to identify outbreaks
How does GIS integrate technology to address environmental issues?
It combines data accessibility, visualization, and modeling tools for comprehensive analysis
Describe how students can use crowdsourcing for environmental research.
They can collaborate with others to collect and share data on local climate impacts
How can sample size impact the reliability of study results?
A larger sample size can improve accuracy and reduce the influence of outliers
