The following three sets of proposals for modification of the International Code of Botanical Nomenclature that relate particularly to fossil plants are recommended for acceptance: Gen. Prop. Prop. C, Art. 1 Prop. A & B (Taxon Prop. 101-103), Art. 9 Prop. H (219), and Art. 38 Prop. A (192), and the following three sets are not recommended for acceptance: Art. 1 Prop. C & D (175-176), Art. 8 Prop. B, Art. 9 Prop. U, & Art. 38 Prop. C (135-137), and Art. 38 Prop. B (193). In addition the Committee considered a number of proposals of general impact and recommended acceptance of Art. 29 Prop. A-C, Art. 30 Prop. A-B, Art. 31 Prop. A-B, Rec. 29A Prop. A-B, & Rec. 30A Prop. A-B (203-213), the proposals on electronic publication, and Div. III Prop. B-C (199-200), but the Committee was undecided on the associated proposals Div. III Prop. D-E (201-202). Although not directly affecting names of fossil plants, the Committee also discussed Art. 36 Prop. A-E (115, 170, 186-188) on the language requirements for the validation of names of new taxa. The members had a positive view of the experience of the restrictive language requirement of either English or Latin for names of fossil plants and would not wish to see a return to allowing any language for validating diagnoses or descriptions.

This award supports a workshop in China to develop collaborations in the field of systematics and biodiversity research between US and Chinese scientists. Discovering and documenting the wealth of Earths biodiversity and determining how these millions of life forms are interrelated are labor intensive activities. International research is a nearly universal aspect of modern systematics, and building effective and productive collaborations is essential. This research requires scientists to cross national boundaries to study plants, animals, fungi, and microbial species in their native habitats. No single country has all the expertise, resources, or human capacity to accomplish this essential research on their own. The United States and China are home to many researchers who are active in systematics, paleontology, biodiversity discovery and related fields, but collaborations are relatively few. It is with these thoughts in mind that this workshop has been organized to discuss the need for greater collaboration between US and Chinese systematists, and mechanisms that will facilitate the development of new collaborative relationships. The focus of the workshop is systematics, broadly defined to include the study of the diversity and evolutionary history of life, including both living and fossil taxa.

The workshop will be three days in length and will include 30 participants and potential collaborators from the US and a similar number of participants from China. Participant selection is based on criteria seeking to: maximize taxonomic diversity representation among the species being studied; find equal representation among scientists working on biodiversity inventory, taxonomy, and phylogeny; provide broad representation of museums, botanic gardens, universities, colleges, and other institutions. Workshop management will be handled by six co-organizers (three in the US and three in China) and a steering committee of three additional participants. After the workshops are concluded the organizers and steering committee will prepare a comprehensive report for public distribution. This workshop will benefit the discipline more broadly by improving scientists abilities to share resources and address a diverse range of questions that depend upon solid understanding of biodiversity and systematic relationships. Enhancement of international collaboration will also benefit individuals directly through enhanced career development.

The rapid diversification and rise to dominance of angiosperms is one of the enduring mysteries of evolutionary biology. While coevolution with animal pollinators is a major driver of angiosperm diversity, the degree of advantage conferred by animal pollination over wind pollination has been controversial, and the rarity of appropriate study systems has hampered progress in understanding the consequences of this transition. This research uses the tropical tree genus Artocarpus (Moraceae)- one of the rare systems exhibiting transitions from wind to animal pollination - to investigate evolutionary implications of that shift. Artocarpus pollination ranges from wind to a unique mutualism mediated by parasitic fungi that provide a brood site and nutrition for fly pollinators. This project provides the opportunity to understand morphological characters associated with pollination shifts, challenge assumptions about reversions from wind to animal pollination, and expose characters that may have been involved in the early radiation of flowering plants as they co-evolved with their animal pollinators. Artocarpus contains several underutilized crops including breadfruit, jackfruit, and terap. This research will support efforts to develop and improve important Artocarpus crops by increasing understanding of their reproductive biology.

The project combines experimental pollinator-exclusion studies with morphological analysis to elucidate pollination mechanisms in Artocarpus and reveal morphological traits correlated with transitions between wind and insect pollination. These transitions will be combined with phylogenomic analyses for the group, to analyze changes in morphology in an evolutionary context, and to resolve the number and direction of wind-insect pollination transitions in Artocarpus. The research uses microsatellite DNA fingerprinting to uncover the domestication history of the insect-pollinated species Artocarpus odoratissimus, one of several underutilized tropical tree crops in this genus. Through collaborations in Malaysia, this project will promote scientific research on a group of underutilized crops in developing tropical regions and provide training in pollination biology to local scientists. The research will also provide research opportunities for undergraduates. The researchers will engage the public through displays at the Chicago Botanic Garden to promote awareness of pollination biology and tropical biodiversity.

This REU Site award to the Chicago Botanic Garden (Glencoe, IL) will support the training of 10 students over 10-week periods during the summers of 2015-2017. This REU Sites focus is on plant biology and conservation, spanning from genomic to ecosystem levels. Mentors are drawn from the Garden, Northwestern University, and partner institutions. Mentors diverse areas of expertise enable students to conduct research on a variety of topics, including evolution, pollination, conservation, genetics, invasive species, soil science, and restoration ecology. Students participate in professional-development activities; field trips; and weekly discussions addressing topics like ethics, graduate school, and scientific communication. The REU program is integrated into a near-peer training continuum: participants are paired with graduate student co-mentors and high school mentees. Target participants include students from groups underrepresented in the sciences, those who are the first in their family to attend college, non-traditional students, veterans, and students who lack extensive research opportunities at their home institutions. Students are recruited nationally and are selected based on their academic record, statement, letter of recommendation, potential to benefit from the experience, interviews with prospective mentors, and program goals.

It is anticipated that a total of 30 students, primarily from groups underrepresented in the sciences and schools with limited research opportunities, will be trained in the program. In addition, the Garden hosts affiliated interns who add to the diverse research community experienced by REU participants. Students will learn how research is conducted, and many will present the results of their work at scientific conferences. All participants will present their findings at a large, multiple-institution symposium.

A common web-based assessment tool used by all REU programs funded by the Division of Biological Infrastructure (Directorate for Biological Sciences) will be used to determine the effectiveness of the training program. Students are tracked to evaluate the effects of this research experience on their future academic and career paths. Information about the program is assessed through follow-up surveys, including use of an REU common assessment tool.
