Sphingolipids Modulate the Inflammatory and Functional Response in mdx Mice
… muscle degeneration and a chronic inflammatory response. Sphingolipid metabolites are associated with the generation or perpetuation of low-grade chronic inflammation critical in atherosclerosis, obesity and cancer. Dietary sphingolipids, however, can suppress intestinal inflammation. We …

Stream functional response to mountaintop removal and valley fill coal mining
Mountaintop removal and valley fill (MTRVF) mining has become a widespread means of coal extraction in the central Appalachians. During MTRVF several hundred meters of overburden are removed to access coal seams, and excess rubble is dumped into adjoining valleys and streams. Filling valleys …

Tumour growth model of cancer self-remission with hassell-varley functional response
Predator-prey like models with functional responses such as Holling type I and II have been studied previously to model the interaction between tumour cells, hunting predator cells and resting predator cells. The aim of this study is to introduce another type of functional response which is …

Investigating the Functional Response of a Subsurface Biofilm Community to Xenobiotic Stress
… spatially and temporally dynamic. Two microbial responses, catabolism and the stress response glutathione-gated potassium efflux (GGKE), to benzene, pentachlorophenol (PCP), or Cd exposure were studied in up-flow sand columns to examine the contribution of each response to the overall functional …

The effect of individual variability and larger carnivores on the functional response of cheetahs
Functional response is the framework thorough which we can quantify how predator hunting behaviors such as rate of successful attack and time spent handling prey interact with prey density to determine the rate at which prey are killed. Cheetahs are mesopredators and their behavior can be shaped by …

Quantifying macroinvertebrate structural and functional response to stream acidification and subsequent recovery in Shenandoah National Park
… streams are characterized by species loss in response to physiological stress and altered food quality resulting from the degradation of microbial (e.g., fungi on leaves) communities. Although freshwater acidification in the U.S. is lessening following reduced industrial emissions, little is …

Defining the functional response of Mycobacterium sp. infected macrophages to structural variants of Interferon gamma (IFN-y)
… this thesis lays a foundation for future functional and mechanistic investigations rather than asserting direct biological outcomes.

The influence of nanotopographical structures on osteoblast adhesion formation and the functional response of mesenchymal stem cell populations
… the adequacy of polymeric materials to withstand functional stresses obliged clinicians to implement these biomaterials in non-load-bearing applications such as fixation of the maxillofacial skeleton. Strategies to guide bone repair, have included topographical modification of these devices in an …

The foraging behaviour of granivorous birds: a mechanistic perspective.
1. The functional response, i.e. the feeding rate as a function of prey density, links resource availability to population level demographic rates. The functional response is often central to behavioural-based population models that predict the effect of environmental changes on populations based …

Assessment and prediction of the potential threats of temperature change and invasive species to the sustainability of Northern Irish sea fisheries
… to novel predator-prey interactions. Comparative functional response analysis has been used to gain insight into resource dependent behaviour and population dynamics. This study is an assessment of the way in which predicted temperature changes can affect resource consumption in three predators. …

Cannabis Exposure During Pregnancy and Neural Mechanisms of Parenting: Assessing Neural Responses to Infant Cues and Parenting Outcomes
… cannabis use during the prenatal period and functional response to infant related stimuli. Study One examines the association between cannabis use during the prenatal period, functional response to infant cries, and explores behavioral interactions between gestation parent and child. This …

Toxicity of selected acaricides on Tetranychus urticae Koch (Tetranychidae: Acari) and Orius insidiosus Say (Hemiptera: Anthocoridae) life stages and predation studies with Orius insidiosus
… of these acaricides to O. insidiosus; 3) the functional response of O. insidiosus to mobile and egg stages of TSSM, in laboratory and greenhouse studies; 4) the abundance of O. insidiosus relative to TSSM densities in peanut. Direct toxicity of three acaricides to TSSM was measured on peanut …

The occurrence and distribution of microplastics in surficial sediments and fish in a South African reservoir
… microplastics characteristics. Subsequently, the functional response approach was developed and applied for quantifications of microplastics uptake by the fish across different environmental densities. Microplastics densities were relatively high during the hot-dry season (mean range 120–6417 …

Pre-release Evaluation of Laricobius osakensis Montgomery and Shiyake (Coleoptera: Derodontidae), a Potential Biological Control Agent for the Hemlock Woolly Adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in the Eastern United States
… and reproduces only on A. tsugae. The functional response "prey consumption changes in response to changes in prey density" was similar for both L. osakensis and Laricobius nigrinus Fender adults. However, L. osakensis had a higher numerical response"changes in oviposition in response …

Bayesian analysis of historical functional linear models with application to air pollution forecasting
Historical functional linear models are used to analyse the relationship between a functional response and a functional predictor whereby only the past of the predictor process can affect the current outcome. In this work, we develop a Bayesian framework for the analysis of the historical …

Population ecology of Pseudacteon tricuspis Borgmeier (Diptera: Phoridae), an introduced parasitoid of the red imported fire ant Solenopsis invicta Buren (Hymenoptera: formicidae) in Louisiana
… aggregation, direct mutual interference and functional response characteristics of this parasitoid were studied to address deficiencies in our knowledge about phorid flies, particularly Pseudacteon parasitoids. This endoparasitoid was discovered to manipulate host ant behavior in ways that …

Intact soil core experiments reveal that temperature and depth influence microbial community function and impact the fate of nitrogenous fertilizer amendments
… narrow at depth, will result in a differential response to N-input. To investigate both the fate of exogenous N-inputs and microbial community and functional response, intact soil cores (0-10 cm and 10-30 cm depth) taken from an agricultural field site in Havana, IL were imbibed with 15N …
