Length-Weight Relationship Of Flier (Centrarchus Macropterus) In Moro Creek, Jeffrey G. Phillips
Length-Weight Relationship Of Flier (Centrarchus Macropterus) In Moro Creek, Jeffrey G. Phillips
ATU Research Symposium
Length-weight relationships provide foundational knowledge for managing fisheries populations. However, there are many species where the length-weight relationships are not widely understood. The Flier (Centrarchus macropterus) is one species where there is a lack of information regarding its length-weight relationship and spatial variation associated with this relationship. A new study was needed to assess the length-weight relationship for this species. Fliers were collected from upper Moro Creek during October 2023. Multiple gears (backpack electrofishing and seining) were employed to increase detection of this species. Length (mm), and weight (g) were recorded for every individual observed. A total of 85 Flier …
The Impact Of Road Crossings On Karst Headwater Streams In Northwest Arkansas, Anthony M. Zenga
The Impact Of Road Crossings On Karst Headwater Streams In Northwest Arkansas, Anthony M. Zenga
ATU Theses and Dissertations 2021 - Present
The karst region of NW Arkansas is home to many headwater endemic Species of Greatest Conservation Need (SGCN). This includes many species of darters, such as Etheostoma cragini, E. microperca, and E. mihileze, as well as crayfish such as Faxonious meeki brevis and F. nana. NW Arkansas is rapidly urbanizing, increasing the need to construct structures like culverts, bridges, and fords. These man-made road crossings can cause stream habitat degradation and fragmentation, as well as impair overall stream connectivity. To evaluate the impact that road crossings have on aquatic SGCN species and their habitat, 30 headwater streams were sampled throughout …
Ecology Of Sceloporus Consobrinus Populations In Two Thermally Different Habitats, Alyssa N. Bangs
Ecology Of Sceloporus Consobrinus Populations In Two Thermally Different Habitats, Alyssa N. Bangs
Theses and Dissertations from 2016
Life history traits in ectotherms are tied to environmental temperature, and many species exhibit morphological and behavioral differences in thermally different habitats. Although these differences are generally attributed to differences in thermal regimes between habitats, most prior research on this topic has been performed across latitudinal or altitudinal gradients. Consequently, I wanted to determine if differences in morphology and behavior are also present among populations of Sceloporus consobrinus that inhabit thermally different habitats at the same latitude and elevation. In this study, I chose sites that fit one of two habitat types: warmer open rocky habitat and cooler, more vegetated …
