clear … Associate in the Group (DM Kaufman), as well as sabbatical support for GG Mittelbach. …

… years ago, respectively, growing steeper through time, until about 10,000 years ago, at
which time the slope became constant (DM Kaufman & JW Williams, unpublished manuscript). …

▪ Abstract Comparative, quantitative biogeographic studies are revealing empirical patterns
of interspecific variation in the sizes, shapes, boundaries, and internal structures of …

Broad‐scale variation in taxonomic richness is strongly correlated with climate. Many mechanisms
have been hypothesized to explain these patterns; however, testable predictions that …

How many times have we as teachers been confronted with situations in which we really
were not sure what to do? We “flew by the seat of our pants,” usually doing with our learners …

Aim We surveyed the empirical literature to determine how well six diversity hypotheses
account for spatial patterns in species richness across varying scales of grain and extent. …

… We began with the updated version of DE Wilson and DM Reeder's taxonomic list of all
known Recent mammals of the world (N = 4629 species) to which we added status, distribution, …

In this paper we will outline several empirical approaches to developing and testing hypotheses
about the determinants of species borders. We highlight environmental change as an …

This chapter describes 10 selected theoretical approaches to education, exploring their
implications for the practice of medical education. The theoretical approaches are social …

… We test IPC on the challenging, frictionally dependent stable structure tests from Kaufman
et al. [Kaufman et al. 2008]. We model both the card house (Figure 5) and masonry arch (…
