Diel And Seasonal Patterns Of Channel Catfish Movement And Habitat Use In The Lower Wabash River, Hanna Gibbs Kruckman
Diel And Seasonal Patterns Of Channel Catfish Movement And Habitat Use In The Lower Wabash River, Hanna Gibbs Kruckman
Masters Theses
Channel catfish Ictalurus punctatus are commonly found throughout the Mississippi River basin and support commercial and recreational fisheries in many large river systems. Understanding population demographics as well as movement patterns and habitat usage can provide a more holistic approach to species management and conservation. Within a 16-km stretch of the lower Wabash River, 27 channel catfish were implanted with acoustic transmitters to monitor fine scale movement and habitat use from September 2014 through April 2016. Channel catfish were located using active tracking during two types of tracking events. Site tracking occurred only during daylight hours and diel tracking monitored …
Demographics And Parasites Of Spotted Bass In The Wabash River, Evan C. Boone
Demographics And Parasites Of Spotted Bass In The Wabash River, Evan C. Boone
Masters Theses
Spotted Bass Micropterus punctulatus Rafinesque are a popular sport fish primarily found in the streams and reservoirs of the south. The Wabash River, a large tributary of the Ohio River, contains a naturally reproducing population on the northern boundary of their range. Currently, the lower Wabash River is monitored using two different sampling designs, the Long Term Electrofishing Program monitors community assemblages using stratified random sampling whereas the Illinois Department of Natural Resources uses a fixed sampling design. Due to the wide distribution but low abundance of Spotted Bass throughout this drainage, captures from each design were compared to assess …
Effects Of Habitat Alteration On Ecomorphology Of Fish Communities In A Restored Stream, Carl Anthony Favata
Effects Of Habitat Alteration On Ecomorphology Of Fish Communities In A Restored Stream, Carl Anthony Favata
Masters Theses
Decades of anthropogenic pressure have devastated lotic ecosystems across the riverscapes of North America, resulting in degradation of critical habitat and contributing to sharp declines in biotic integrity. In response, local stream restoration projects have increased in frequency. However, little effort has been allocated to monitoring and project success has been limited. In addition, restoration projects typically focus on ecological effects above the population-level, while relationships with physiological processes are seldom assessed. Lessons from the long-term restoration and ecological monitoring of Kickapoo Creek highlight some of the complex dynamics driving reach-scale restoration projects. Following instream restoration, I predicted that alterations …

Stopover Ecology Of Neotropical Migratory Songbirds In The Northern Yucatan Peninsula, Mexico, Lauren E. Solomon
Stopover Ecology Of Neotropical Migratory Songbirds In The Northern Yucatan Peninsula, Mexico, Lauren E. Solomon
Masters Theses
Chapter I. Full-service hotels, convenience stores or fire escapes? Evaluating function of stopover sites for Neotropical migrants in the northern Yucatan Peninsula
Nearctic-Neotropical migratory songbirds incur the highest mortality rates during their annual migrations. Migratory songbirds use a network of stopover sites to rest, refuel, or seek refuge during times of poor weather conditions; and the time and energy expended at these sites exceeds that of migratory flight. In order to conserve stopover sites with the highest value to Neotropical migrants, a conceptual framework was developed to classify stop over sites into three functional categories based on their function for …
Quantifying Bat Detection Survey Methods And Activity Patterns, Tara C. Hohoff
Quantifying Bat Detection Survey Methods And Activity Patterns, Tara C. Hohoff
Masters Theses
Bats have an astonishing diversity and provide vital ecosystem services in an array of different niches. In North America, most species of bats are insectivores and tend to be frequently overlooked for their important ecosystem role providing insect control. As bat populations have declined in recent years, farmers, land managers, conservationists, and bat enthusiasts have wondered what we can do to protect our local bat populations. As a first step, we need to develop methods that more effectively survey for rare species of bats. By performing inefficient surveys, we are doing a disservice to our funding agencies providing misinformation that …
