However, application of such approaches to empirical systems is hampered by a lingering series of theoretical and practical bottlenecks. The community is still wrestling with the challenges of how to develop species‐level, comprehensively sampled phylogenies and associated geographic and phenotypic resources that enable global‐scale analyses. We illustrate difficulties and opportunities using the rosids as a case study, arguing that assembly of biodiversity data that is scale‐appropriate—and therefore comprehensive and global in scope—is required to test global‐scale hypotheses. Synthesizing comprehensive biodiversity data sets in clades such as the rosids will be key to understanding the origin and present‐day evolutionary and ecological dynamics of the angiosperms." /> <meta name="DC.publisher" content="Columbia University Press" /> <meta name="DC.publisher" content="Wiley Periodicals, Inc." /> <meta name="DC.subject" content="comparative methods" /> <meta name="DC.subject" content="data layers" /> <meta name="DC.subject" content="scientific infrastructure" /> <meta name="DC.subject" content="rosids" /> <meta name="DC.subject" content="Rosidae" /> <meta name="DC.subject" content="phylogeny" /> <meta name="DC.title" content="Challenges of comprehensive taxon sampling in comparative biology: Wrestling with rosids" /> <meta name="DC.type" content="Article" xml:lang="en_US" /> <meta name="DC.rights" content="IndexNoFollow" /> <meta name="DC.subject" content="Biology" /> <meta name="DC.subject" content="Botany" /> <meta name="DC.subject" content="Science" /> <meta name="DC.description" content="Peer Reviewed" /> <meta name="DC.description" content="https://deepblue.lib.umich.edu/bitstream/2027.42/143800/1/ajb21059.pdf" /> <meta name="DC.description" content="https://deepblue.lib.umich.edu/bitstream/2027.42/143800/2/ajb21059_am.pdf" /> <meta name="DC.identifier" content="10.1002/ajb2.1059" /> <meta name="DC.identifier" content="American Journal of Botany" /> <meta name="DC.identifier" content="Salisbury, B.

However, application of such approaches to empirical systems is hampered by a lingering series of theoretical and practical bottlenecks. The community is still wrestling with the challenges of how to develop species‐level, comprehensively sampled phylogenies and associated geographic and phenotypic resources that enable global‐scale analyses. We illustrate difficulties and opportunities using the rosids as a case study, arguing that assembly of biodiversity data that is scale‐appropriate—and therefore comprehensive and global in scope—is required to test global‐scale hypotheses. Synthesizing comprehensive biodiversity data sets in clades such as the rosids will be key to understanding the origin and present‐day evolutionary and ecological dynamics of the angiosperms.</div> </div> <div class="simple-item-view-description-fix item-page-field-wrapper table"> <h2 style="font-size: 18px;">Publisher</h2> <div>Columbia University Press<div class="spacer"> </div>Wiley Periodicals, Inc.<div class="spacer"> </div> </div> </div> <div class="simple-item-view-description-fix item-page-field-wrapper table"> <h2 style="font-size: 18px;">ISSN</h2> <div>0002-9122<div class="spacer"> </div>1537-2197<div class="spacer"> </div> </div> </div> <div class="simple-item-view-description-fix item-page-field-wrapper table"> <h2 style="font-size: 18px;">Other DOIs</h2> <div> <a href="http://dx.doi.org/10.1002/ajb2.1059">10.1002/ajb2.1059</a> </div> </div> <div class="simple-item-view-description-fix item-page-field-wrapper table"> <h2 style="font-size: 18px;">Types</h2> <div>Article</div> </div> <div class="simple-item-view-uri item-page-field-wrapper table"> <h2 style="font-size: 18px;">Handle</h2> <span><span itemprop="url"><a href="https://hdl.handle.net/2027.42/143800">https://hdl.handle.net/2027.42/143800</a></span></span> </div> <div class="simple-item-view-uri item-page-field-wrapper table"> <span></span> </div> <div class="simple-item-view-show-full item-page-field-wrapper table"> <h2 style="font-size: 18px;">Metadata</h2> <a href="/handle/2027.42/143800?show=full">Show full item record</a> </div> <div class="simple-item-view-collections item-page-field-wrapper table"> <h2 style="font-size: 18px;">Collections</h2> <ul class="ds-referenceSet-list">  <li> <a href="/handle/2027.42/21621">Interdisciplinary and Peer-Reviewed</a> </li> </ul> </div> </div> </div> </div> </div> </div> </div> <div class="itemViewStaticText"> <h3 style="font-size: 18px; font-weight: bold">Remediation of Harmful Language</h3> <p style="font-size: 18px">The University of Michigan Library aims to describe library materials in a way that respects the people and communities who create, use, and are represented in our collections.
