Regional and Seasonal Effects on Long Bone Fracture Characteristics
… may be related to exposure to different seasonal and regional climatic conditions, as studies have been conducted in diverse geographical locations and during different seasons. Alternatively, or in addition, differences may be attributed to methodological approaches used to describe and …

Seasonal Effects on the Geochemical Evolution of the Logsdon River, Mammoth Cave, Kentucky
… 10 km of continuous base-level conduit included seasonal sampling of carbon dioxide partial pressures (Pco2)> dissolved ions, and saturation indices for calcite (SIcal). The highest PC02 values are found at the upstream site, closest to the Sinkhole Plain recharge area, which creates …

Host and Seasonal Effects on the Infection Dynamics of Skrjabinoptera Phrynosoma (Ortlepp) Schulz, 1927, a Parasitic Nematode of Horned Lizards
<p>Author's Abstract: Skrjabinoptera phrynosoma (Ortlepp) Schulz, 1927 is a common parasitic nematode of horned lizards. The life cycle of S. phrynosoma was described by Lee in 1957, but has received little attention since. The present study addressed effect of season as well as host …

Seasonal effects of elevated carbon dioxide, competition, and water stress on gas exchange and growth of loblolly pine and sweetgum grown in open-top chambers
Loblolly pIne (Pinus taeda) and sweetgum (Liquidambar styraciflua) were grown in miniature stands at 7.6-cm spacings outdoors in open-top chambers (4.6 m in diameter and 3.5 m tall) for 16 months. Treatments consisted of ambient- and elevated-CO₂ , drought-stressed and well-watered, and stand type …

Herptile Abundance and Diversity in Response to Seasonal Burning on a Central Texas Ashe Juniper-Live Oak Savanna
Current research on the effects of fire on herpetofauna generally has ignored the timing of a burn. I investigated the seasonal effects (summer versus winter) of prescribed burning on the herpetofaunal community of a central Texas Ashe juniper-live oak savanna. One trapping line, consisting of 1 …

Coordination of inventory distribution & price markdowns for clearance sales at Zara
… Clearance sales depend on the pricing, seasonal effects, and the assortment of goods available to the customer. Errors in inventory distribution and clearance pricing result in loss of potential revenue or excess inventory to be salvaged. In the case of Spanish-based retailer Zara, …

Permanent Deformation Behaviour of Unbound Granular Materials in Pavement Constructions
… constructions under consideration of the seasonal effects. From this data a serviceability limit line (plastic shakedown limit) stress boundary for the unbound granular materials (UGM) was defined for different moisture contents. Below this line the material will have stable behavior. The …

Comparing reversal-learning abilities, sucrose responsiveness, and foraging experience in scout and non-scout honey bee (Apis mellifera) foragers
… also suggested an interaction between the effects of foraging role (scout or non-scout) and seasonal effects on reversal-learning abilities. Second, I hypothesized that variation in responsiveness to sucrose rewards is associated with scouting behavior. I found no significant difference in …

Quantification of the effects of heavy agricultural vehicle loading on pavement performance.
… objective of this study was to investigate the effects of farm equipment on the structural responses (stresses and strains) of flexible and rigid pavements. The goal of the project was to not only quantify the pavement damage caused by this heavy farm equipment compared to the damage caused by a …

Seasonal patterns of colonization by protozoa in an oligotrophic lake
Seasonal effects on protozoan colonization of polyurethane foam (PF) units were investigated in.an oligotrophic lake, Mountain Lake, Virginia. PF units were placed into the lake's pelagic water to simulate barren habitat islands suitable for colonization by protozoa. The results were interpreted …

Assessing Respiration Rates and Nutrient Dynamics of Aritifical Reef Biofilms and Bacterioplankton in the Mississippi Sound
… biofilm growth observed at low profile reefs. Seasonal effects were also observed. Respiration and nutrient production rates were positively correlated with temperature, and 813C and 81sN values were enriched during warmer seasons, all of which indicate higher benthic and water column …

RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
… similar across the treatments, though there were seasonal effects on litter mass loss. Our findings suggest that oligohaline marshes, specifically those dominated by S. patens, are not limited by nitrogen to the same extent as salt marshes.

Soil Microbial Community Dynamics In Florida Scrub Ecosystem
… are maintained by fires which vary in frequency, seasonality, and intensity. Florida oak-saw palmetto scrub ecosystem is characterized by fires occurring at intervals of 10-20 years. Diverse factors as private land acquisition and development has created a patchy distribution of scrub ecosystems …

Tree Canopy Effects on Roof-Harvested Rainwater in East Texas
… measured in 2016-2017 in order to evaluate the effects of arboreal overhang on roof-harvested rainwater quality collected in East Texas. Three treatments were evaluated: Rainwater collected from roofs without any overhanging tree vegetation, rainwater collected from roofs under predominantly …

Energy deposition in the lower auroral ionosphere through energetic particle precipitation
… of absorption is investigated along with seasonal effects which are shown to be reliant on geomagnetic activity. A study of the large number of solar proton events from 1995 to 2001 inclusive is carried out with particular reference to those that produce significant absorption in the …

Sea surface distribution of nitrous oxide and methane in European shelf seas and the Atlantic Ocean
… waters is unclear, but may be attributed to seasonal cooling and a potential microbial N2O consumption pathway. The dominant pathway for N2O formation in the open ocean is nitrification. Both nitrification and denitrification may be important in the production of N2O in shelf seas. Vertical …

Land Cover and Culvert Effects on Stream Physical Water Quality in West Central Georgia
… of Economic Development. To account for seasonal variability in water quality, measurements were taken in the spring (n=12) and the summer (n=12). The watershed analysis revealed that urbanization had no impact on water temperatures, but temperatures were higher in the summer than in the …

Belowground success: Collembola as indicators of restoration progress following active and passive restoration
… and winter and spring (2021) to consider the seasonal effects. From a total of 250 samples, 77,880 individual specimens and 34 morphospecies were collected and identified. Results showed that Collembola assemblages differed significantly among the different restoration treatments, especially …
