Effect Of Temperature On Questing Activity Of Ixodes Scapularis In A Laboratory Setting, Molly Meagher
Effect Of Temperature On Questing Activity Of Ixodes Scapularis In A Laboratory Setting, Molly Meagher
Thinking Matters Symposium
Understanding deer tick (Ixodes scapularis) behavior is increasingly important due to the species’ northerly range expansion, and consequently, increased human contact. Deer ticks are a major public health concern, as they are the primary vector of Lyme disease and other serious diseases. Differences in questing behavior are of considerable interest as fluctuating weather due to climate change effect the species’ range expansion and time spent questing. Although previous research has examined temperature preferences of tick behavior, there are conflicting reports about direct effects on questing activity. Therefore, I addressed the relationship between temperature and questing behavior of adult deer ticks. …
How Genetics Plays A Role In Avian Migration, Tyler Bauersfeld
How Genetics Plays A Role In Avian Migration, Tyler Bauersfeld
Thinking Matters Symposium
Avian migration is an adaptive response to seasonal environments, which means that birds move from one region to another on migratory routes due to environmental factors. Migratory behavior is ubiquitous within and among many bird species, and this poster will review two studies of how migratory behavior is affected on a genetic level as well as how avian migration has independently evolved in many different lineages. A study of the Eurasian blackcap from southern France demonstrates how environmental factors and parent lineages affect the genetic behavior of migration. This study also demonstrated how sedentary populations of birds have been shown …
Effects Of Ibuprofen On Duration Of Fear Responses In Red Claw Crabs, Ryan Shaffer
Effects Of Ibuprofen On Duration Of Fear Responses In Red Claw Crabs, Ryan Shaffer
Thinking Matters Symposium
Pharmaceutical pollution is a growing environmental issue. Chemicals engineered to affect humans persist in the water system and may have unintended effects on animal behavior. Ibuprofen is an anti-inflammatory drug shown to reduce predator avoidance in fish. I chose to examine the effects of ibuprofen on the foraging behavior of red clawed crab (Perisesarma bidens) by measuring time spent in the open. Crabs typically spend most of their time hiding and only expose themselves to danger in order to forage for food. I predicted that crabs treated with the high dose of ibuprofen will spend less time hiding compared to …
