Spectral mapping and long-term seasonal evolution of Pluto
… maps revealing striking latitudinal and longitudinal variations. We begin by studying the methane distribution and surface colors using data from New Horizons' Ralph/MVIC instrument. From this study we find that Pluto's equatorial region shows a broader diversity of terrains and more …

Plant Community Responses to Long-Term Seasonal Bison Grazing in the Dry Mixed Grassland of Saskatchewan
… understood how plant communities respond to seasonal bison grazing. This study investigated plant community responses to long-term dormant and growing season bison grazing as well as an ungrazed control. The study took place in the dry mixed grass ecoregion of Saskatchewan, Canada and …

Long term seasonal and annual changes in rainfall duration and magnitude in Luvuvhu River Catchment, South Africa
This study was aimed at investigating the long term seasonal and annual changes in rainfall duration and magnitude at Luvuvhu River Catchment (LRC). Rainfall in this catchment is highly variable and is characterised of extreme events which shift runoff process, affect the timing and magnitude of …

Three essays on the UK Electricity Market: Risk Premium,Uncertainty of Supply and Forecasting
… this, a new method is proposed to estimate the long-term seasonal component, named as the multi-stage optimization filter with a leading Phase Shift (MOPS) to filter the data into trend and residual, and then forecasts for the trend and residual are generated separately and later combined. The …

Rapid social regulation of 3β-HSD activity in the songbird brain
… androgens are generally associated with short-term aggressive challenges in many breeding vertebrates. However, some animals such as song sparrows (Melospiza melodia) are aggressive year-round, even during the non-breeding season, when gonads are regressed and systemic testosterone (T) levels …

Characterization of Sea Turtle Nesting on the Upper Texas Coast
… monitoring indicated this male established long-term seasonal residency on offshore Louisiana foraging grounds. Nesting and telemetry data indicate the UTC is becoming increasingly important to the Kemp?s ridley population. However, current regulations do not support the sustainment of the …

The Effect of Environmental Perturbations on the Plant Phyllosphere Microbiome
… the relative importance of stochastic and deterministic processes applied heterogeneously across the habitat in time or space. The phyllosphere is the aboveground surface of plants on which microbial communities, composed primarily of Bacteria, but also including Archaea and microbial …

Investigation of Methane Emissions and Sources
… at the Moody Tower site indicated the relative long-term seasonal and diurnal dynamics of regional CH4. The diurnal variation of CH4 in different seasons showed the same trend with the highest values happened in the early morning and lower values during the daytime. The calculated δ13CCH4 …

Effects of oceanic and atmospheric phenomena on precipitation and flooding in the Manafwa River Basin
An investigation was performed to determine the relationship between certain oceanic and atmospheric phenomena and the precipitation patterns in the Manafwa River Basin of eastern Uganda. Such phenomena are the El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). The indices that …

Nutrients and their role in promoting cyanobacterial growth along the Murray River, Australia
… experiments, in-situ microcosm experiments and long-term seasonal monitoring was conducted. Microcosm experiments were run in-situ over 2020–2021 to examine whether N or P or a combination of both, limited phytoplankton and cyanobacterial growth during warmer temperature bloom periods. These …

The Effect of Pavement Temperature on Frictional Properties of Pavement Surfaces at the Virginia Smart Road
… relation to highway safety. Both short- and long-term seasonal variations have been observed in friction measurements. These variations have been attributed to different factors, such as traffic, rainfall, and temperature. Since both the tire rubber and the HMA pavement surface are …

Long-term ground response For borehole heat exchangers in clay
… for space heating and cooling. Designs for seasonal heat exchange systems are becoming increasingly popular in urban environments to reduce energy costs and contribute in decreasing carbon emissions. Broader applications require more careful evaluation of hydro-mechanical behavior of soil to …

Evaluation Of Pavement Surface Friction Seasonal Variations
… it has been observed that both short- and long-term seasonal variations impact wet-pavement friction. Temperature, rainfall, and contaminants accumulated on the pavement surface affect the friction measurements. The objective of this thesis was to quantify the effect of seasonal variations …

Spatiotemporal dynamics of grounwater in the Andean Highlands in northern Ecuador
… and Darcian-based formulations were used to determine the groundwater dynamics by means of some essential variables that SWAT model does not provide. A SWAT model was configured over the period 2006¿2015. A stationarity analysis prior implementing the numerical model was implemented to …
