NECROBIOME SUCCESSION IN COLD CONDITIONS
… occurred during a transition from laboratory conditions to environmental conditions and could have played a role. The other donor in this study demonstrated an increase in abundance and a decrease in biodiversity during the same timeframe. More necrobiome research needs to be done to determine …

Evaluating the Impact of Environmental Conditions on the Cocaine Odorant Methyl Benzoate
… of research as to the role of environmental conditions on canine performance, however, a tangential gap in literature lies in the effects of controlled target odor emission in these changing environments. Thus, the goal of this study is to evaluate the effects of various environmental …

The Role of Temperature in the Preparation and Viability of Rodent Brain Slices, and Propensity to Evoke Spreading Depolarization
… brain will undergo a bout of SD induced by the cold. Temperature also plays a role in the preparation of rodent brain slices. Brain slicing is a fundamental method used in cellular neuroscience research, and it is common practice to submerge the brain in ice-cold artificial cerebrospinal fluid …

Insights into the seasonal ecology and thermal biology of the lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae)
… interest in alternative strategies such as cold-based interventions, including ambient and chilled aeration. Yet, the effectiveness of these methods depends on a variety of factors, including grain type, insect density, environmental conditions, and exposure duration. Here, our study …

THE EFFECT OF WINTER VERSUS SUMMER RUNNING ON LOWER EXTREMITY MUSCULOSKELETAL INJURY RATE IN RECREATIONAL RUNNERS
… of cryotherapy on body tissues suggest that cold exposure can decrease performance measures, including proprioception, strength, and agility. Since a decrease in proprioception and strength have been linked with an increase of injury rates, this suggests that exposure to cold conditions may …

Late Jurassic to Early Cretaceous stable isotope and geochemical records from the northern high latitudes: implications for palaeoclimate
… widely accepted as being dominated by greenhouse conditions with elevated CO2 levels and warm polar regions. Although much compelling evidence to support this idea of global warmth exists, some recent studies propose that the greenhouse climate may at times have been punctuated by sub-freezing …

Factors influencing the induction of diapausing egg production in the calanoid copepod Diaptomus leptopus
… a decrease in the onset of diapause under cold conditions and the overall timing of onset of diapause egg production in the experimental populations differed from that of the field populations giving indirect evidence that each population are responding to the available cues as predictors …

Phylogeny and Biogeography of Ice Crawlers (Insecta: Grylloblattodea): Evidence from Six Molecular Loci
… Grylloblatta) are known for their adaptation to cold conditions. Phylogenetic relationships among grylloblattid species and genera are not known. Late Pleistocene glaciations had a major effect on the current Grylloblatta distribution, because their specific habitat requirements restrict them to …

Gulf stream temperature, salinity and transport during the last millennium
… The timing of reduced flow is consistent with cold conditions in Northern Hemisphere paleoclimate archives, implicating Gulf Stream heat transport in centennial-scale climate variability of the last 1,000 years. The pattern of flow anomalies with depth suggests reduced LIA transport was due to …

A laboratory and performance evaluation of clothing assemblies which incorporate sliver-knit fabrics.
… temperature control in man and the effect of a cold environment are reviewed and outlined. The properties of fibres and fabrics as they relate to thermal insulation within a clothing assembly are considered and moisture vapour retention and transmission within the assembly and the relationship …

A stable isotope and macro-charcoal sediment record spanning the Pleistocene-Holocene transition from Maple Pond in the southern Shenandoah Valley, Virginia, USA
… fire activity, possibly related to warmer drier conditions during the Mid-Holocene Maximum and a shift to fire-adapted forest (oak, hickory, pine). A smaller charcoal peak between 120 and 130 cm may relate to rapid warming at the end of the Younger Dryas, a shift back to cold conditions around …

The Effects of Heat and Cold on Cognitive Function and Endurance Capacity
… of mental and physical function in hot and cold environments is more challenging compared to thermoneutral environments due to increases systemic physiological and psychological strain. The mechanism for impairments in both cognitive and physical function may be due to early perturbations in …

Functional analysis of candidate flowering time genes from the model legume Medicago truncatula
… to long day length and vernalisation (winter cold) conditions. A putative Medicago Polycomb Repressive Complex 2 (PRC2) subunit VERNALISATION2 (MtVRN2) was characterised previously in the Putterill laboratory, whose mutation led to early flowering. This indicated that MtVRN2 represses the …

Historical and contemporary drivers of greenhouse gas emissions from upland soils
… decrease soil O2 concentrations, creating conditions conducive for anaerobic biogeochemical reactions that produce and consume nitrous oxide (N2O) and carbon dioxide (CO2). In addition to the contemporary effects of ponding on soil O2 concentrations, repeated ponding of soils in …

Living near permanent water in the upper Murray-Darling Basin Implications from the micromorphology of buried soils near artesian springs
… landscapes change and why? How did dry and humid conditions effect the circumstances and behaviours of early peoples living in Australia’s drylands? It is hypothesised that early peoples were able to adjust their behaviours to cope with episodic erosional events and successfully occupy drylands …

Bacterial Blight of Soybean: Survival, Yield Reduction, and Disease Progress Model
… March 1983. PRS-81 survived better under dry cold conditions than under wet warm conditions. Effects of soil moisture on survival of PRS-81 were greater at 4 C than at 12 C or -12 C. The relationship between bacterial blight severity and yield and 300-seed weight of soybean cultivars Wells II …

The development and evaluation of engineering strategies to enhance microbial oil production for industrial applications
… thraustochytrids. Yeast strains exhibited strong cold adaptive traits, achieving high specific growth rates and lipid productivity, and biomass concentrations of up to 14 g/L when cultivated at 10°C. Thraustochytrid strains remained relatively consistent biomass concentration and yields across all …

Enhancement of cold tolerance and growth of tomato plants using endophytic bacteria isolated from cold-adapted plants
Cold stress is a key abiotic factor that adversely impacts crop production. Climate change is responsible for warm winter periods that allow crop production under partial protection, such as commercial greenhouses and tunnels used for tomato production in Sicily. However, temperature conditions are …
