Data From: Root Distributions Predict Shrub-Steppe Responses To Precipitation Intensity, Andrew Kulmatiski, Karen H. Beard

Browse all Datasets

Precipitation events are becoming more intense around the world, changing the way water moves through soils and plants. Plant rooting strategies that sustain water uptake under these conditions are likely to become more abundant (e.g., shrub encroachment). Yet, it remains difficult to predict species responses to climate change because we typically do not know where active roots are located or how much water they absorb. Here, we applied a water tracer experiment to describe forb, grass, and shrub root distributions. These measurements were made in 8 m by 8 m field shelters with low or high precipitation intensity. We used …

The Influence Of Grazing Systems On Bird Species Richness And Density In The Nebraska Sandhills, Silka L.F. Kempema, Walter H. Schacht, Larkin A. Powell

School of Natural Resources: Faculty Publications

Grazing is the de facto method of habitat management used in much of the Nebraska Sandhills. Ranchers use a variety of grazing systems, and our goal was to evaluate the effects of systems on grassland birds. We estimated the species richness and density of grassland birds for three grazing systems used on private ranches: long, medium, and short duration grazing systems. We observed sixty species, and the grazing system with pastures utilizing long duration grazing periods had the highest estimates of species richness as well as the most heterogeneous habitat structure. Differences in species richness among systems were most pronounced …

Drought In The Breadbasket Of America And The Influence Of Oceanic Teleconnections, Olivia G. Campbell, Gregory B. Goodrich

School of Natural Resources: Faculty Publications

From 1980 to 2020, drought events accounted for only 11.4% of the billion-dollar disasters in the United States (U.S.), yet caused the second-highest total amount in damages, at USD 236.6 billion. With the average cost of a drought being upwards of USD 9.5 billion, these natural disasters can create serious problems in agriculture. Drought is defined as a period of below-average precipitation that causes damage to agriculture and water supplies. Previous research has linked drought events in the U.S. Great Plains to oceanic teleconnections in the Pacific and Atlantic basins, indicating the influence of El Niño—Southern Oscillation (ENSO), the Pacific …

Vegetation And Habitat Classification Of Created And Natural Brackish Marshes Via Unoccupied Aerial Systems And Potential Monitoring Applications, Seth T. Chapman

LSU Master's Theses

Louisiana’s coastal marshes are some of the most valuable natural, economic, and cultural state resources that however, have been severely deteriorating over the last century. Federal and state agencies have pooled billions of dollars into coastal restoration projects in Louisiana of which marsh creation is a primary focus. Traditional monitoring of created marshes involves in-situ vegetation sampling and aerial imagery from fixed-wing occupied aircraft, but these methods have limitations and/or can negatively impact sites. My thesis explores the use of Unoccupied Aerial Systems (UAS; i.e., drones) to classify vegetation and habitat in coastal marsh systems, compare habitat and vegetation cover …

Bush And Revegetation Recovery After Fire On Farms In Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

This page gives some ideas on how to reduce the risk of fires in bush and revegetation on farms, and how to speed recovery of burnt areas.

Large patches of bush in good condition will generally regenerate well after fire, with some management of weeds and grazing.

Revegetation areas are much more susceptible to fire, and recovery largely depends on the age of the revegetation and after-fire management.

United States Department of Agriculture Wildlife Services: Staff Publications

Investigating the influences of single nucleotide polymorphisms (SNP) associated with conceptus death (CD) on day 16 of pregnancy could distinguish cows who have inferior value for fertility traits. We hypothesized that CD is associated with SNP genotypes that disrupt maternal recognition and lead to early pregnancy loss. RNA sequences from Holstein cow pregnancies (n = 15) with normal conceptuses (Norm) or CD were subjected to SNP discovery via Qiagen CLC Genomics Workbench. Selected SNP were based on previous fertility studies, differentially expressed genes within pregnancy development analyses and proximity to SNP associated with fertility traits in the Cattle QTL …

Skin Lipids Alone Enable Conspecific Tracking In An Invasive Reptile, The Argentine Black And White Tegu Lizard (Salvator Merianae), M. Rockwell Parker, Eric A. Tillman, Lauren A. Nazarian, Megan L. Barlowe, Julianna M. Lincoln, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Locating potential mates in non-native habitats is one of the most important challenges faced by invasive vertebrate species. The Argentine black and white tegu lizard (Salvator merianae) is a major invasive reptile species in the contiguous United States and is rapidly expanding its range across Florida and the Southeast, in part due to inadequate management strategies and tools. Because a wide array of reptiles, especially squamates (snakes and lizards), have been well-studied for their reliance on chemical cues to locate conspecifics, our project aimed to isolate chemical cues from tegus and assess the ability of adult males and …
