 All of these possibilities suggest more scrutiny of disciplinary heterogeneity in biological investigation relevant to reductionism. Although ecology has received some treatment (Dupré 1993, ch. 5; Mikkelson 2004), issues of decomposition and representation have not yet received wide attention (Lafrançois 2006). Other topics connected to explanatory reduction and mechanisms in experimental research are cancer (Bertolaso 2013, 2016, Bizzarri et al. 2008, Moss 2002, Plutynski 2013, Soto and Sonnenschein 2005, 2006) and stem cells (Fagan 2013, Laplane 2016). Because of the diversity of explanations found in these different disciplines, the nature of scientific explanation returns with a vengeance (Schaffner 2006). Although only a few reductionists demand that explanation be strictly nomological (Rosenberg 2006, Weber 2005), the subtle interplay between explanation and reduction must be treated when ranging over diverse biological subdisciplines. Additionally, as more attention is given to the diversity of investigative reasoning (or “scientific practice”) in and among these disciplinary contexts, the interplay between different aspects of methodological and epistemic reduction will become more salient.
