Computers in Wildlife Research & Conservation By: Ashley Sloan April 23, 2008
Before the use of Computers in the wildlife field • Observations were handwritten • Calculations done manually • Lead to larger percentages of human error • Less accuracy • Didn’t have ability to monitor wildlife movements At all times
Solution to the problem of human error?? • Researchers & Biologist use computers and computer programs for solutions regarding conservation strategies for threatened and endangered wildlife
Threats to wildlife &endangered species • Main threat: Habitat loss, fragmentation, and degradation due to human development • Use computer programs to come up with strategies to save land • For ex: How much land does the endangered Florida panther require???
Solution =Computers • Use telemetry data & Gps data -telemetry- is the transfer of information through radio waves -gives where, how long, how far the panther traveled -computer receives, monitors, & gathers data -Global Positioning System satellites transmit signals to equipment & computers on the ground
Global Positioning System Telemetry Data ( transmitters to computer) (use satellites)
It was found through the use of computer programs and data collected and monitored by the computers that…. • Males disperse longer distances, but their movements were circular and were less than those exhibited by other cougar populations • Human landscape features limit colonization and forces dispersing panthers to remain nearby or return toward their natal ranges • Females were philopatric • Without this information, Wildlife conservationist would not know where to start in order to save this endangered species
Wildlife Research, Conservation Strategies & Computers • used digital land cover data & maps on computers -categorized the maps into 7 general habitat types • Used: <1 as habitat types with distance ratios that were significantly selected & >1 were habitats avoided
Florida Panther Research • Researches used Euclidean distance-based analysis -a computer program which estimated the distance of animal locations to habitats in order to figure out what type of habitat panthers preferred
Land cover maps Land cover maps are created & visualized on a computer. They help visualize a large area. In wildlife research, they make land cover maps for each habitat that the animal uses.
Conservation Computer Programs -The Panther Model • Spatially explicit model (SEM) • Estimates the actual & potential influence human factors have on wildlife occupying a landscape • Geographic Information System • Represents landscape as landscape images • Also includes: roads, deer density, human density, & public conservation landscape images • 30 X 30 m pixel grid
Conservation Computer Programs The Panther Model • Model inputs a small population of 7 virtual panthers • Panthers placed in different areas of the study area- “North Florida” • Panther: looks, chooses, & moves to the desired cell • Movement history & coordinates for each panther is stored . All panther locations are tallied for each pixel of landscape & a GIS map is created to show overall population usage • It’s like a video game……… • Also used for other endangered animals for ex: African cheetah,
“Tags” • Tags are designed and manufactured by Wildlife Computers ***available for wildlife and ecological research. • *** offer different tag types for recording the behavior and distribution of marine animals. • Animal is tagged and research information shown and analyzed on computer • There are specialized shapes to suit various species
Overall Computers aid in…….. • Monitoring local movement of endangered or threatened species • Creating land cover maps • Monitoring long distance dispersal between genders -Immigration *To more accurately predict the effects of human factors on the endangered or threatened species *To indicate home range size, amount of road crossings, road mortality, land cover selection
Overall Computers aid in…….. • Wildlife management & conservation is a large and important science. Information from research is greatly needed to make accurate decisions regarding species conservation. • Computers allow researchers to learn more and apply what is best in order to save endangered and threatened species
