At the beginning of the twentieth century, the biologist Joseph Grinnell made a distinction between science and sentiment for producing fact-based generalizations on how to conserve biodiversity. We are inspired by Grinnellian science, which successfully produced a century-long impact on studying and conserving biodiversity that runs orthogonal to some familiar philosophical distinctions such as fact versus value, emotion versus reason and basic versus applied science. According to Grinnell, unlike sentiment-based generalizations, a fact-based generalization traces its diverse commitments and thus becomes (...) tractable for its audience. We argue that foregrounding tractability better explains Grinnell’s practice in the context of his time as well as in the context of current discourse among scientists over the political “biases” of biodiversity research and its problem of “reproducibility.”.

In the early twentieth century, ornithology underwent significant changes. So far, these changes, basically, have been studied by focussing on the elite of professional biologists working at universities or state museums. However, important developments also occurred in what Lynn Nyhart has called “the civic realm” of science – the sphere given form by private naturalist associations, nature writers, taxidermists and school teachers. This article studies the changing dynamics of civic ornithology, by looking at one particular case: the influential orinthological observatory (...) in Rossitten, East-Prussia. This observatory, the first of its kind, was founded in 1901 and led, for the first three decades of its existence, by the minister Johannes Thienemann. This article analyses the ornithological practices Thienemann developed in Rossitten and the rhetoric he used to defend these practices. In both, so it is argued, one finds a mixture of the traditional, locally anchored naturalist approach with the new ideals of the “modern” and “experimental” university laboratories. The innovations which Thienemann introduced in this hybrid form of ornithology called for specific spatial strategies which made optimal use of the natural chatacteristics of his workplace and which mobilized a large civic network of geograhically scattered amateurs. At the same time, his work also altered the space he shared with the birds – materially, conceptually and culturally. Thus, this article maintains Thienemann's ornithology can only be understood by acknowledging its continuous interaction with the geographical and civic context in which it arose. (shrink)

I propose we abandon the unit concept of "the evolutionary synthesis". There was much more to evolutionary studies in the 1920s and 1930s than is suggested in our commonplace narratives of this object in history. Instead, four organising threads capture much of evolutionary studies at this time. First, the nature of species and the process of speciation were dominating, unifying subjects. Second, research into these subjects developed along four main lines, or problem complexes: variation, divergence, isolation, and selection. Some calls (...) for 'synthesis' focused on these problem complexes (sometimes on one of these; other times, all). In these calls, comprehensive and pluralist compendia of plausibly relevant elements were preferred over reaching consensus about the value of particular formulae. Third, increasing confidence in the study of common problems coincided with methodological and epistemic changes associated with experimental taxonomy. Finally, the surge of interest in species problems and speciation in the 1930s is intimately tied to larger trends, especially a shifting balance in the life sciences towards process-based biologies and away from object-based naturalist disciplines. Advocates of synthesis in evolution supported, and were adapting to, these larger trends. (shrink)
