We re-processed the regressions incorporating the sheep population as a new independent variable as a possible predictor of the guanaco population growth rate (l); so our new analysis increased from 5 to 6 independent variables: sheep population, guanaco population size, winter temperature, winter temperature with a lag of 1 year, annual precipitation, annual precipitation with a lag of 3 years.
2) Re-processed the regressions incorporating the sheep population as a new independent variable of the guanaco population growth rate (l); so our new analysis now has 6 independent variables: sheep population, guanaco population size, winter temperature, winter temperature with a lag of 1 year, annual precipitation and annual precipitation with a lag of 4 years.
In hierarchical models, greater variance of summer and winter temperature was associated with larger effects for hot and cold days, respectively, on respiratory deaths.
However, winter temperature of 2014, 2015 did not drop below 10 °C on consecutive days.
Average summer temperature is 30°C from June to September, and average winter temperature is 15°C from November to March.
The Antarctic has an average elevation of 7,590 feet with an average winter temperature of minus 65 Fahrenheit.
The North Atlantic Current moderates Svalbard's temperatures, particularly during winter, giving it up to higher winter temperature than similar latitudes in Russia and Canada.
The difference between our results and those of Sarno et al. (1999) may reflect that these authors used the average winter snowfall while we considered average winter temperature.
At Turin the average winter temperature is 32.5 °F (0.3 °C) and the summer average 74 °F (23 °C).
Lastly, interactions between winter temperature, snow cover and fine-root mortality may contribute to the winter temperature sensitivity of Scots pine.
The lowest recorded winter temperature is -90C.
