“…This is likely to reduce the associated somatic costs of torpor (such as oxidative stress, reduced immunocompetence and neuronal damage[ 21 ]), indicating intraspecific variation of energetics during hibernation. In contrast, other studies [ 9 , 22 – 25 ] have not found evidence of this.…”

Background Despite centuries of research, debate remains on the scaling of metabolic rate to mass especially for intraspecific cases. The high variation of body mass within brown bears presents a unique opportunity to study the intraspecific effects of body mass on physiological variables. The amplitude of metabolic rate reduction in hibernators is dependent on body mass of the species. Small hibernators have high metabolic rates when euthermic but experience a drastic decrease in body temperature during torpor, which is necessary to reach a very low metabolic rate. Conversely, large hibernators, such as the brown bear (Ursus arctos), show a moderate decrease in temperature during hibernation, thought to be related to the bear’s large size. We studied body mass, abdominal body temperature, heart rate, and accelerometer-derived activity from 63 free-ranging brown bears (1–15 years old, 15–233 kg). We tested for relationships between body mass and body temperature, heart rate, and hibernation duration. Results The smallest individuals maintained lower body temperatures during hibernation, hibernated longer, and ended hibernation later than large bears. Unlike body temperature, winter heart rates were not associated with body mass. In summer, the opposite pattern was found, with smaller individuals having higher body temperature and daytime heart rates. Body mass was associated with body temperature in the winter hypometabolic state, even in a large hibernating mammal. Smaller bears, which are known to have higher thermal conductance, reached lower body temperatures during hibernation. During summer, smaller bears had higher body temperatures and daytime heart rates, a phenomenon not previously documented within a single mammalian species. Conclusion We conclude that the smallest bears hibernated more deeply and longer than large bears, likely from a combined effect of basic thermodynamics, the higher need for energy savings, and a lower cost of warming up a smaller body.

This paper summarizes current political discussions and reports on xenophobic demonstrations and racist riots in the Saxon city of Chemnitz and contrasts them with the global context of the brand image of a premium watch manufacturer. Chemnitz is a city in Saxony (in East Germany) with approx. 250,000 inhabitants. It examines the impact of images in the media and videos the medium-sized company NOMUS. The manufacturer is the company of NOMUS, a medium-sized manufacturer of luxury watches. NOMUS sold its luxury products in international cities all over the world. The production of watches takes place in the small town > Glashütte <. Glashütte is approx. 80 km away from Chemnitz, approx. 7,300 inhabitants live in Glashütte. NOMUS supplies a worldwide dealer network with subsidiaries in the USA, Canada, Cuba, Argentina, the U.A.E., India, China, Japan, Australia and Europe. NOMUS has 250 employees in the glassworks and 50 employees in a design studio in Berlin. The main purpose of the research is to present the regional effects of racism in a Central German city on the national level of Germany and to evaluate the global economic effects for the location Germany as such and the premium manufacturer of high-priced watches in particular. Subsequently, individual solutions for the local situation in the company and strategies for global marketing are subsumed. To describe the emergence of brand values, scientific literature is used; to systematize the current media coverage, the daily press must be used, in deviation from the scientific claim, since there are significant indications that the daily press has a significant influence on the perspective of the end customers of the premium watch manufacturer in the B2C business. A quantitative collection of customer data is dispensed with, and the expert interview is used as a methodical tool with the owners and managing directors of the watch manufacturer NOMUS 1. The aim of the research is also to empirically analyses the countermeasures taken in the company NOMUS and to theoretically confirm their transferability to similar constellations. The research can be useful for the targeted control of reconnaissance campaigns and the targeted control of marketing activities in the international target countries. The article should explicitly not be a political classification of the current demonstrations. The article should not occupy any pages. The article only examines the impact of regional media events on NOMUS' global business.
