Avian Ecological Succession In The Amazon: A Long-Term Case Study Following Experimental Deforestation, Cameron L. Rutt, Vitek Jirinec Nov 2019

Avian Ecological Succession In The Amazon: A Long-Term Case Study Following Experimental Deforestation, Cameron L. Rutt, Vitek Jirinec

Faculty Publications

Approximately 20% of the Brazilian Amazon has now been deforested, and the Amazon is currently experiencing the highest rates of deforestation in a decade, leading to large-scale land-use changes. Roads have consistently been implicated as drivers of ongoing Amazon deforestation and may act as corridors to facilitate species invasions. Long-term data, however, are necessary to determine how ecological succession alters avian communities following deforestation and whether established roads lead to a constant influx of new species. We used data across nearly 40 years from a large-scale deforestation experiment in the central Amazon to examine the avian colonization process in a …


Incubation Recess Behaviors Influence Nest Survival Of Wild Turkeys, Nicholas W. Bakner, Bret A. Collier, Landon R. Schofield Nov 2019

Incubation Recess Behaviors Influence Nest Survival Of Wild Turkeys, Nicholas W. Bakner, Bret A. Collier, Landon R. Schofield

Faculty Publications

In ground nesting upland birds, reproductive activities contribute to elevated predation risk, so females presumably use multiple strategies to ensure nest success. Identification of drivers reducing predation risk has primarily focused on evaluating vegetative conditions at nest sites, but behavioral decisions manifested through movements during incubation may be additional drivers of nest survival. However, our understanding of how movements during incubation impact nest survival is limited for most ground nesting birds. Using GPS data collected from female Eastern Wild Turkeys (n = 206), we evaluated nest survival as it relates to movement behaviors during incubation, including recess frequency, distance traveled …


Oyster Reefs In Northern Gulf Of Mexico Estuaries Harbor Diverse Fish And Decapod Crustacean Assemblages: A Meta-Synthesis, Megan K. La Peyre, Danielle Aguilar Marshall, Lindsay S. Miller Oct 2019

Oyster Reefs In Northern Gulf Of Mexico Estuaries Harbor Diverse Fish And Decapod Crustacean Assemblages: A Meta-Synthesis, Megan K. La Peyre, Danielle Aguilar Marshall, Lindsay S. Miller

Faculty Publications

Oyster reefs provide habitat for numerous fish and decapod crustacean species that mediate ecosystem functioning and support vibrant fisheries. Recent focus on the restoration of eastern oyster (Crassostrea virginica) reefs stems from this role as a critical ecosystem engineer. Within the shallow estuaries of the northern Gulf of Mexico (nGoM), the eastern oyster is the dominant reef building organism. This study synthesizes data on fish and decapod crustacean occupancy of oyster reefs across nGoM with the goal of providing management and restoration benchmarks, something that is currently lacking for the region. Relevant data from 23 studies were identified, representing data …


Evaluation And Enhancement Of Carbon Sequestration Potential Of Existing Vegetation Along Roadsides, Vikram Kapoor, Jeffrey Hutchinson, Samer Dessouky Aug 2019

Evaluation And Enhancement Of Carbon Sequestration Potential Of Existing Vegetation Along Roadsides, Vikram Kapoor, Jeffrey Hutchinson, Samer Dessouky

Data

Corresponding data set for Tran-SET Project No. 18HSTSA01. Abstract of the final report is stated below for reference:

"The objectives of this study were to evaluate the vegetative composition and carbon sequestration potential of vegetation along a major roadway in Texas. Soil and vegetation were evaluated along IH-35 within Bexar County for composition and carbon content. Three 20 m transects were placed at each site and percent vegetative cover was estimated and above ground plant biomass, and soil was collected from three 0.25 m2 subplots along each transect. Plant and soil samples were analyzed for carbon content. Two non-native grasses, …
