In this paper, habitat models were used to predict potential habitat for endangered species, which is an important question in landscape and conservation planning. Based on logistic regression, we developed habitat distribution models for the burnet moth Zygaena carniolica and the nymphalid butterfly Coenonympha arcania in Northern Bavaria, Germany. The relation between adult occurrence and hab...

Since Ehrlieh and Morgenroth (5) first published their famous horror autotoxicus concept hundreds of observations have been made supporting the idea that the formation of deleterious antibodies against an organism's own antigen is an exceptional event, if possible at all. Investigations on human ABO blood groups have furnished the best. known example of obedience to the biological principle of ...

Upon reading Christopher Goodnow’s recent Review article in Cell, which emphasized the overlapping role of somatic mutation in autoimmunity and cancer (Goodnow, 2007), I was reminded of a graduate lecture course given by Professor Roderick MacLeod in 1995 at the University of Illinois. While introducing F.M. Burnet’s clonal selection theory to our small class, Professor MacLeod mentioned Burnet...

Fresh forages are an important natural source of vitamins and fatty acids in ruminant diets, and their concentrations in forage species are important for the quality of animal-derived foods such as dairy and meat products. The aims of this study were to obtain novel information on vitamins and fatty acids (FA) in a variety of forage legumes and non-legume forb species compared to a grass-clover...

In 1938 Dodd, Buddingh and Johnson observed that the virus of herpes simplex could be isolated with ease from typical cases of aphthous stomatitis in infants, so providing presumptive evidence of its etiological association with the disease. In the following two years this work was extended by Burnet and Lush (1939) and Burnet and Williams (1989). They confirmed that the virus could be isolated...

In the past 50 years, immunologists have accumulated an amazing amount of information as to how the immune system functions. However, one of the most fundamental aspects of immunity, how the immune system discriminates between self vs. non-self, still remains an enigma. Any attempt to explain this most intriguing and fundamental characteristic must account for this decision at the level of the ...
