Evidence for Local Adaptation in Birds
… to subarctic sites experienced significantly colder temperatures, and tended to suffer higher egg and nestling mortality due to climatic conditions (cold temperatures), than locally transplanted subarctic nests. Adult females breeding in subarctic sites that received temperate nests changed …

Experimental Study of Tire Inner Liner
… to the loading direction in samples tested at cold temperatures (-40 C in this study). Also, an experimental Arcan fixture was used in conjunction with digital image correlation to learn the full-field strain state of the inner liner material under simulated loading conditions. It was found …

Influence of environmental conditions on the age, hatch dates, and growth of juvenile Atlantic menhaden in the Choptank River, MD
… bottleneck in Atlantic menhaden caused by cold temperatures. Hatch-dates of surviving juveniles were skewed towards warmer months for years characterized by colder temperatures. Reduced larval growth rates, influenced by reduced temperature and food availability, carried over to juvenile …

Molecular Evolution in the Mountains: Genetic Affinity and the Environment led to Adaptive Variation in the American Pika (Ochotona princeps)
… <em>Ochotona princeps</em> encounters cold temperatures, hypoxia, and dietary toxins, and therefore has thermoregulatory, metabolic, and behavioral adaptations related to these environmental challenges. Studies have confirmed interspecific adaptive variation between <em>O. princeps</em> …

Effect of ball impact location and temperature on softball bat handle vibration
… across three bat brands and at three different temperatures. The bat barrel was struck with an impact hammer and an accelerometer placed near the handle of the bat collected the output data. Following an experiment conducted at room temperature, the bats were placed in extreme heat and cold and …

The Effect of Temperature on the Material Stiffness of Field Hockey Balls for Material Selection
… balls made of PVC breaking in half when hit in cold weather. Hockey ball manufacturers are interested in the effect of temperature on balls breaking to inform ball design and material selection. To test whether hockey balls are easier to break in cold temperatures, this study measured the …

Water Chestnut: Field Observations, Competition, and Seed Germination and Viability in Lake Ontario Coastal Wetlands
… was examined to assess development stage and cold-stratification requirements. Water lily was the better competitor of the two, but water chestnut had very high germination success. Water chestnut germination does not seem to be inhibited by temperature or by exposure to shade. The seeds do, …

Comprehensive investigation of using tire-derived aggregate in chip seal subjected to various traffic and environmental conditions
… the performance of chip seal in intermediate temperatures. However, increasing the rubber content improved the performance under higher speeds, heavier vehicles, snowplowing action, and elevated temperatures. Using crumb rubber will also help with better surface drainage. Rubberized chip seal …

Transcriptomic analysis of the response of the lactic acid bacteria Lactococcus piscium for the identification of possible adaptive genes during thermal shock in cold and warm temperatures
… this study, to analyze in a transcriptome level, cold and heat shock stress to spoilage lactic acid bacteria, a time-dependent RNA-seq for Lactococcus piscium with a temperature of 0 °C and 28 °C was conducted. The data of protein regulation during the experiment shows that Lactococcus piscium has …
