In 'Big Ecology,' David C. Coleman documents his historically fruitful ecological collaborations in the early years of studying large ecosystems in the United States. As Coleman explains, the concept of the ecosystem--a local biological community and its interactions with its environment--has given rise to many institutions and research programs, like the National Science Foundation's program for Long Term Ecological Research. Coleman's insider account of this important and fascinating trend toward big science takes us from the paradigm of collaborative interdisciplinary research, starting with the International Geophysical Year (IGY) of 1957, through the International Biological Program (IBP) of the late 1960s and early 1970s, to the Long-Term Ecological Research (LTER) programs of the 1980s.

Antibodies are the functional unit of humoral immunity. They are secreted by plasma cells, a type of B lymphocyte. When on the surface of a B cell, these molecules are immunoglobulins, following secretion they are termed as antibodies. Antibodies are found in bodily fluids and tissue spaces and are most effective in eliminating extracellular pathogens. As compared to mammalian antibodies, IgY offers various advantages for the targeted extraction of antibodies and their application in bioanalysis. Since the antibodies are extracted from the yolks of laid eggs, the method of antibody production is non-invasive. Thus, no blood must be taken from the animals for the extraction of blood serum. Because of its economic importance most research on immunity implied in the reactivity of the body were performed on domestic birds. Direct consequence of this research is the understanding of fundamental and applied concepts of immunity in birds. Comparing to the mammalian, avian immune system appears insignificant. However, it currently provides important information regarding the fundamental immunological mechanisms. It also provided a significant number of firsts, especially in vaccinology.

C. T. Russell Originally published in the journal Space Science Reviews, Volume 136, Nos 1&#8211;4. DOI: 10. 1007/s11214-008-9344-1 © Springer Science+Business Media B. V. 2008 The Sun-Earth Connection is now an accepted fact. It has a signi cant impact on our daily lives, and its underpinnings are being pursued vigorously with missions such as the Solar TErrestrial RElations Observatory, commonly known as STEREO. This was not always so. It was not until the middle of the nineteenth century that Edward Sabine connected the 11-year geomagnetic cycle with Heinrich Schwabe&#8217;s deduction of a like periodicity in the sunspot record. The clincher for many was Richard Carrington&#8217;s sighting of a great whi- light are on the Sun, on September 1, 1859, followed by a great geomagnetic storm 18 hours later. But was the Sun-Earth Connection signi cant to terrestrial denizens? Perhaps in 1859 it was not, but a century later it became so. Beginning in the 1930&#8217;s, as electrical powergrids grew in size, powercompanies began to realize that they occasionally had power blackouts during periods of intense geomagnetic activity. This correlation did not appear to be suf ciently signi cant to bring to the attention of the public but during the International Geophysical Year (IGY), when geomagnetic activity was being scrutinized intensely, the occurrence of a large North American power blackout during a great magnetic storm was impossible to ignore.
Europe has a distinguished history of environmental research and hosts many of the world s leading researchers in the environmental field. Environmental concerns have been on the policy agenda since the European Comunities were created in 1957. The International Geophysical Year (IGY) was launched in the same year as a first attempt to coordinate global measurements of the Earth, the oceans, the atmosphere and the sun. It also pointed out for the first time that carbon dioxide was building up in the atmosphere. The decades since then have witnessed increasing public concern about our environment and the damage being done to it, alongside greater research efforts to increase knowledge and find solutions.

To help salve the sting of orbiting Sputniks, the United States needed a dramatic demonstration of technological prowess; early in 1958, the White House ordered a top secret under-ice transit of the Arctic Ocean--Pacific to Atlantic--via the North Pole. And that spring, the Office of Naval Research initiated a unique project: to assess whether non-rigid airships (blimps) could support field parties deployed in the Arctic. This book recounts two successful missions. In August, the nuclear submarine Nautilus (SSN 571) reached 90 North and, continuing under ice, logged the first deep-ocean transit of the basin. En route to rendezvous with an IGY drifting station on T-3, an ice island, U.S. Navy airship BUNO 126719 became the sole military airship to cross the Arctic Circle. This work is based on first-hand accounts, including journal excerpts from Dr. Waldo Lyon a force behind U.S. under-ice submarine development
