Influence Of Habitat And Intrinsic Characteristics On Survival Of Neonatal Pronghorn, Christopher N. Jacques, Jonathan A. Jenks, Troy W. Grovenburg, Robert Wayne Klaver
Influence Of Habitat And Intrinsic Characteristics On Survival Of Neonatal Pronghorn, Christopher N. Jacques, Jonathan A. Jenks, Troy W. Grovenburg, Robert Wayne Klaver
Natural Resource Management Faculty Publications
Increased understanding of the influence of habitat (e.g., composition, patch size) and intrinsic (e.g., age, birth mass) factors on survival of neonatal pronghorn (Antilocapra americana) is a prerequisite to successful management programs, particularly as they relate to population dynamics and the role of population models in adaptive species management. Nevertheless, few studies have presented empirical data quantifying the influence of habitat variables on survival of neonatal pronghorn. During 2002–2005, we captured and radiocollared 116 neonates across two sites in western South Dakota. We documented 31 deaths during our study, of which coyote (Canis latrans) predation (n = 15) was the …

The Importance Of Analyzing Neighbor Competitive Response In The Target–Neighbor Experimental Design, Kevin J. Berry, Michele R. Dudash
The Importance Of Analyzing Neighbor Competitive Response In The Target–Neighbor Experimental Design, Kevin J. Berry, Michele R. Dudash
Natural Resource Management Faculty Publications
The role of competition in community structure and species interactions is universal. However, how one quantifies the outcome of competitive interactions is frequently debated. Here, we review the strengths and weaknesses of the target– neighbor design, a type of additive design where one of the competing species is reduced to a single individual and where controls and analyses are used for the target, but not for the neighbors. We conducted a literature review to determine how the target–neighbor design has been typically used and analyzed. We found that historically, targets were often smaller than neighbors and introduced after neighbor establishment; …

Agronomy, Horticulture and Plant Science Faculty Publications
Bud dormancy in grapevine is an adaptive strategy for the survival of drought, high and low temperatures and freeze dehydration stress that limit the range of cultivar adaptation. Therefore, development of a comprehensive understanding of the biological mechanisms involved in bud dormancy is needed to promote advances in selection and breeding, and to develop improved cultural practices for existing grape cultivars. The seasonally indeterminate grapevine, which continuously develops compound axillary buds during the growing season, provides an excellent system for dissecting dormancy, because the grapevine does not transition through terminal bud development prior to dormancy. This study used gene expression …

Buteo Nesting Ecology: Evaluating Nesting Of Swainson’S Hawks In The Northern Great Plains, Will M. Inselman, Shubham Datta, Jonathan Jenks, Kent Jensen, Troy Grovenburg
Natural Resource Management Faculty Publications
Swainson’s hawks (Buteo swainsoni) are long-distance migratory raptors that nest primarily in isolated trees located in areas of high grassland density. In recent years, anthropogenic conversion of grassland habitat has raised concerns about the status of the breeding population in the northern Great Plains. In 2013, we initiated a study to investigate the influence of extrinsic factors influencing Swainson’s hawk nesting ecology in north-central South Dakota and south-central North Dakota. Using ground and aerial surveys, we located and monitored nesting Swainson’s hawk pairs: 73 in 2013 and 120 in 2014. We documented 98 successful breeding attempts that fledged …
Probing The Past 30-Year Phenology Trend Of Us Deciduous Forests, X. Yue, N. Unger, Xiaoyang Zhang, C.S. Vogel
Probing The Past 30-Year Phenology Trend Of Us Deciduous Forests, X. Yue, N. Unger, Xiaoyang Zhang, C.S. Vogel
GSCE Faculty Publications
Phenology is experiencing dramatic changes over deciduous forests in the USA. Estimates of trends in phenology on the continental scale are uncertain, however, with studies failing to agree on both the magnitude and spatial distribution of trends in spring and autumn. This is due to the sparsity of in situ records, uncertainties associated with remote sensing data, and the regional focus of many studies. It has been suggested that reported trends are a result of recent temperature changes, though multiple processes are thought to be involved and the nature of the temperature forcing remains unknown. To date, no study has …

Early Weaning Reduces Rangeland Herbage Disappearance, Patricia Johnson, Kenneth C. Olson, Roger N. Gates, Hubert H. Patterson, Mindy Hubert, Douglas Landbloom, Janna J. Kincheloe, Heather A. Richter, Allison V. Grove
Natural Resource Management Faculty Publications
Early weaning of beef calves reduces nutrient and forage demand in a cow–calf enterprise, potentially contributing to reduction in forage utilization on the pasture from which calves are removed by a nonlactating cow vs. a cow–calf pair. Research was conducted to evaluate weaning beef calves 90 days early (EW) vs. normal weaning (NW) on pasture herbage disappearance in mixed-grass prairie pastures in the northern Great Plains. Spring-calving cows (n = 48) were utilized in each study year (2003, 2004, and 2006) from the date of early weaning (August) until the date of normal weaning (November). Cow–calf pairs were randomly …
Mate Replacement And Alloparental Care In Ferruginous Hawk, Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg
Mate Replacement And Alloparental Care In Ferruginous Hawk, Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg
Natural Resource Management Faculty Publications
Alloparental care (i.e., care for unrelated offspring) has been documented in various avian species (Maxson 1978, Smith et al. 1996, Tella et al. 1997, Lislevand et al. 2001, Literak and Mraz 2011). A male replacement mate that encounters existing broods has options, which include alloparental care or infanticide. Infanticide may be beneficial in some species (Rohwer 1986, Kermott et al. 1990), but in long-lived avian species, like the ferruginous hawk (Buteo regalis) that do not renest within a season, infanticide might be detrimental. Adoption and rearing success likely provide direct evidence of competence of replacement mates as potential parents for …

Emerging infectious diseases (EID) present significant threats to the conservation of global biodiversity (Daszak et al. 2000). Evaluating impacts (spatial, temporal and demographic) of EIDs on sensitive and declining wildlife populations is challenging because quantitative information is usually dependent on estimates rather than counts (Wobeser 2007) and mortality rates are seldom quantified with conventional monitoring (Naugle et al. 2005).
Metabolic Theory Explains Latitudinal Variation In Common Carp Populations And Predicts Responses To Climate Change, Michael J. Weber, Michael L. Brown, David H. Wahl, Daniel E. Shoup
Metabolic Theory Explains Latitudinal Variation In Common Carp Populations And Predicts Responses To Climate Change, Michael J. Weber, Michael L. Brown, David H. Wahl, Daniel E. Shoup
Natural Resource Management Faculty Publications
Climate change is expected to alter temperature regimes experienced by fishes, which may also alter life history traits. However, predicting population-level responses to climate change has been difficult. Metabolic theory of ecology has been developed to explain how metabolism controls a variety of ecological processes, including life history attributes. Thus, this theory may be a useful tool for predicting fish population responses to climate change. To understand how climate change may alter freshwater fish life history, we measured population characteristics (e.g., recruitment, growth, body size, and mortality) of 21 North American common carp Cyprinus carpio populations spanning a latitudinal gradient …

Non-Target Effects Of Clothianidin On Monarch Butterflies, Jacob R. Pecenka, Jonathan G. Lundgren
Natural Resource Management Faculty Publications
Monarch butterflies (Danaus plexippus) frequently consume milkweed in and near agroecosystems and consequently may be exposed to pesticides like neonicotinoids. We conducted a dose response study to determine lethal and sublethal doses of clothianidin using a 36-h exposure scenario. We then quantified clothianidin levels found in milkweed leaves adjacent to maize fields. Toxicity assays revealed LC10, LC50, and LC90 values of 7.72, 15.63, and 30.70 ppb, respectively. Sublethal effects (larval size) were observed at 1 ppb. Contaminated milkweed plants had an average of 1.14 ±0.10 ppb clothianidin, with a maximum of 4 ppb in a …
The Ecological Significance Of Emerging Deltas In Regulated Rivers, Malia A. Volke, Michael L. Scott, W. Carter Johnson, Mark Dixon
The Ecological Significance Of Emerging Deltas In Regulated Rivers, Malia A. Volke, Michael L. Scott, W. Carter Johnson, Mark Dixon
Natural Resource Management Faculty Publications
Sedimentary deltas forming in the world’s regulated rivers are a glaring gap in our knowledge of dammed riverine ecosystems. Basic ecological information is needed to inform the current debate about whether deltas should be retained and managed to gain ecosystem services lost under reservoirs or whether they should be partially removed to improve flow conveyance and to resupply sediment-starved reaches below dams. An examination of nine deltas on the heavily regulated upper and middle Missouri River showed the following: The sizes, dynamics, and biotic communities vary widely across deltas; riparian forest has established on portions of most deltas; the current …

Natural Resource Management Faculty Publications
In South Dakota, breeding giant Canada geese (Branta canadensis maxima) have increased substantially, and harvest management strategies have been implemented to maximize hunting opportunity (e.g., special early-September seasons) on local, as well as molt-migrant giant Canada geese (B. c. interior) while still protecting lesser abundant Arcticbreeding Canada geese and cackling geese (e.g., B. hutchinsii, B. minima). Information on important parameters, such as survival and recovery rates, are generally lacking for giant Canada geese in the northern Great Plains. Patterns in Canada goose band recoveries can provide insight into the distribution, chronology, and harvest pressures to which a given goose population …

Research conducted, including the rationale: Weeds reduce yield in soybeans through incompletely defined mechanisms. The effects of weeds on the soybean transcriptome were evaluated in field conditions during four separate growing seasons. Methods: RNASeq data were collected from 6 biological samples of soybeans growing with or without weeds. Weed species and the methods to maintain weed free controls varied between years to mitigate treatment effects and to allow detection of general soybeans weed responses. Key results: Soybean plants were not visibly nutrient or water stressed. We identified 55 consistently down-regulated genes in weedy plots. Many of the down-regulated genes were …

Sdsu Calf Value Discovery 2013/2014 Summary Report, J.A. Walker, W.C. Rusche
South Dakota Beef Report, 2015
The Calf Value Discovery Program (CVD) allows cow‐calf producers to gain knowledge of the finishing segment of the beef cattle industry and the marketing of fed cattle. Specifically, CVD provides an opportunity for cow‐calf producers to learn how their calves perform in a feedlot and their carcass value when sold in a value‐based marketing system. Each producer taking part in the program could consign 5 or more steers weighing between 500 and 800 pounds to the CVD program. Animals were finished at VanderWal Yards (Bruce, SD) in a calf‐fed program using typical diets and management protocols. Carcass and feedlot performance …

South Dakota Beef Report, 2015
A finishing phase study was conducted to measure the effectiveness of replacing dry rolled corn with a high inclusion liquid feed for finishing steers. Treatments were based upon 3 supplements: 1) Control 3.3% inclusion meal-type supplement (CO); 2) Typical Liquid Supplement 4.5% inclusion liquid supplement (TLS); and 3) High Liquid Supplement 9.0% inclusion liquid supplement (HLS). Supplements displaced dry rolled corn in finishing diets. Five 5 pens of 7 or 8 yearling steers with an initial BW of 930 lb assigned to each treatment for the 119 d experiment. The assayed supplement inclusion averaged 3.35%, 4.48% and 8.97% for the …
Postruminal Flow Of Glutamate Linearly Increases Small Intestinal Starch Digestion In Cattle, E.J. Blom, D.W. Brake, D.E. Anderson
Postruminal Flow Of Glutamate Linearly Increases Small Intestinal Starch Digestion In Cattle, E.J. Blom, D.W. Brake, D.E. Anderson
South Dakota Beef Report, 2015
Improving performance and efficiency among cattle fed corn-based diets could have large benefit to cattle production in the United States. Starch escaping ruminal fermentation is not efficiently digested in the small intestine; however, postruminal flows of casein (i.e., milk protein) or glutamate (an amino acid or building block of protein) increase small intestinal starch digestion in cattle. The objective of this study was to determine responses of small intestinal starch digestion in cattle to increasing amounts of postruminal glutamate. Increasing amounts of duodenal glutamate linearly increased small intestinal and postruminal starch digestion. These data indicate that postruminal glutamate can provide …
Effect Of Processing Conditions On Nutrient Disappearance Of Cold-Pressed And Hexane-Extracted Camelina And Carinata Meals In Vitro, A. Sackey, E.E. Grings, D.W. Brake, K. Muthukumarappan
Effect Of Processing Conditions On Nutrient Disappearance Of Cold-Pressed And Hexane-Extracted Camelina And Carinata Meals In Vitro, A. Sackey, E.E. Grings, D.W. Brake, K. Muthukumarappan
South Dakota Beef Report, 2015
Camelina and carinata are oilseed crops that have recently gained increasing attention as biofuel sources. The meals remaining after oil extraction contain relatively high concentration of protein and, because of this, there is interest in using them in livestock diets. However, the nutritional qualities of these meals are not well defined and may vary with processing conditions. In our experiment, we evaluated meals from cold-pressed and solvent-extracted camelina and carinata meals manufactured using 6 different processing conditions. Estimates of total in vitro OM and CP disappearance of each meal were determined according to a modified 2-phase procedure of Tilley and …

Comparison Of Camelina Meal And Distiller’S Dried Grains With Solubles In Diet Of Beef Replacement Heifers, E.E. Grings, A. Sackey, D.W. Brake, G.A. Perry
South Dakota Beef Report, 2015
Biofuel production from different crops yields by-product meals that are available for use as protein sources for ruminant livestock. Variation in nutrient composition among meals may result in different inclusion rates to meet nutrient needs of livestock. In this study we compared distiller’s dried grains with solubles (DDGS), a by-product of ethanol production, and camelina meal, a by-product of biodiesel production, as a protein source in hay-based diets for beef heifers before breeding. Diets were formulated to be similar in energy and protein content by altering the amount of protein source and corn in the diet. Heifers fed the two …
