Influences of large-scale climatic variability on reindeer population dynamics: implications for reindeer husbandry in Norway
There is increasing evidence that the globe is currently warming, with changes being more pronounced in northern latitudes. Understanding the ecological effects of climatic variability is therefore important. There is recent support for the idea that a large-scale atmospheric phenomenon, the North Atlantic Oscillation (NAO), through its effects on vegetation and regional weather conditions, inf...
متن کاملResponse time variability
This paper presents a work-in-progress on the response time variability problem. This problem occurs whenever events, jobs, clients or products need to be sequenced so as to minimize the variability of time they wait for their next turn in obtaining the necessary resources. The problem has numerous real-life applications, which will be briefly reviewed. The problem has distinctive number theore...
متن کاملThe Role of the Time Allowed for Mating on Variability
In rats variation of fetal weights among litters is significantly greater than variation of fetal weights within litters. This phenomenon is called the litter effect. Twenty litters of Wistar rats were studied to determine whether or not variation in the duration of the period allowed for copulation (1.5 hours versus 15 hours) was a cause of the litter effect. Analyses of variance showed that t...
متن کاملResponse of birds to climatic variability; evidence from the western fringe of Europe.
Ireland's geographic location on the western fringe of the European continent, together with its island status and impoverished avifauna, provides a unique opportunity to observe changes in bird migration and distribution patterns in response to changing climatic conditions. Spring temperatures have increased in western Europe over the past 30 years in line with reported global warming. These h...
متن کاملSimulating the response of natural ecosystems and their fire regimes to climatic variability in Alaska1
The dynamic global vegetation model MC1 was used to examine climate, fire, and ecosystems interactions in Alaska under historical (1922–1996) and future (1997–2100) climate conditions. Projections show that by the end of the 21st century, 75%–90% of the area simulated as tundra in 1922 is replaced by boreal and temperate forest. From 1922 to 1996, simulation results show a loss of about 9 g C·m...
