Climate change and CONN collection

The Biodiversity Research Collection provides learning opportunities beyond EEB. Daniela Doncel, a journalism and French double major and student in creative writing at the University of Connecticut created a video now posted on Youtube that focuses on research conducted by EEB researchers in South Africa. Ms. Doncel is also the News Director at WHUS Radio at UConn and the president of the UConn Coalition of Writers, a creative writing club at the Storrs campus.

She met Tanisha Williams, a Ph.D. candidate in EEB in the Holsinger and Schlichting labs, through a science and journalism communications course in which undergraduate journalism students and graduate STEM students learned to better communicate through the art of interviewing. Tanisha was her first interview in the class, and she was able to learn a bit about her research in South Africa. Ms. Doncel was immediately interested because of the international aspect of the research as well as her curiosity over the genus Tanisha was studying. Throughout the semester of fall 2017, Ms. Doncel took on the challenge of taking the complexity of Tanisha’s research and explaining it in a short amount of time with a visual medium. With this experience, she learned many new skills as a journalist, and had the opportunity to share what she learned about the importance of Tanisha’s research.

The learning experience was two directional: for Ms. Doncel the BRC provided an opportunity to learn about climate change research and for Ms. Williams, the creation of this video provide an opportunity to practice her science communication skills.

New proposal for the Cape Horn Biosphere Reserve

The recent exploration of the bryophyte and lichen flora of the Diego Ramirez archipelago South of Cape Horn in subantarctic Chile contributed to the development of a proposal for the extension of the Cape Horn Biosphere Reserve, an effort led by Dr. Ricardo Rozzi, a former student in EEB and now Professor at the University of North Texas and the Universidad de Magallanes (Chile). Click on the image for access to the on-line publication.

The bryophyte collections from Gonzalo Island, the first from this island about 100 km SW of Cape Horn, are currently being studied and the inventory of the tiny, low elevation and treeless island will be shared through a co-authored publication involving Dr. J. Engel and M. von Konrat from the Field Museum and of course our Chilean colleagues. Unicates will be deposited in the herbarium of the University of Concepcion (Chile) and duplicates in CONN and F.

Tapeworm book featured in UCONN today

The recently published book “Tapeworms from the vertebrate bowels of the earth” edited by Drs. Janine Caira (EEB—UCONN) and Kirsten Jensen (EEB—University of Kansas) (see our previous post)  was featured in UCONN Today with a gallery of stunning pictures of tapeworms, a group of organisms well represented in UCONN’s Biodiversity Research Collection.

Army Ant video reaches milestone

As part of the NSF funded project for the preservation of the Army Ant Guest Collection (AAGC), both videos created by Carl Rettenmeyer were shared with the public via Youtube.

This week, the documentary “Astonishing Ants” reached a milestone: the video has been viewed 10,000 times! The companion film “Associates of Eciton burchellii” has been viewed over 4200 times!

The video is widely praised by the viewers: “I learned 100x more in this video compared to a NatGeo doc” — “…refreshingly spartan” — “Fine documentaries like this should go viral” — “Possibly the best most in-depth doc i have ever seen on ants, particularly on army ants.thank u Dr.R. your hard work is appreciated”

New publication on mosses

Medina R., M. Johnson, Y. Liu, N. Wilding, T. Hedderson, N. Wickett & B. Goffinet. 2018. Evolutionary dynamism in bryophytes: Phylogenomic inferences confirm rapid radiation in the family Funariaceae. Molecular Phylogenetics and Evolution 120: 240–247. pdf

Abstract reads: Rapid diversifications of plants are primarily documented and studied in angiosperms, which are perceived as evolutionarily dynamic. Recent studies have, however, revealed that bryophytes have also undergone periods of rapid radiation. The speciose family Funariaceae, including the model taxon Physcomitrella patens, is one such lineage. Here, we infer relationships among major lineages within the Entosthodon-Physcomitrium complex from virtually complete organellar exomes (i.e., 123 genes) obtained through high throughput sequencing of genomic libraries enriched in these loci via targeted locus capture. Based on these extensive exonic data we (1) reconstructed a robust backbone topology of the Funariaceae, (2) confirmed the monophyly of Funariaand the polyphyly of Entosthodon, Physcomitrella, and Physcomitrium, and (3) argue for the occurrence of a rapid radiation within the Entosthodon-Physcomitrium complex that began 28 mya and gave rise more than half of the species diversity of the family. This diversification may have been triggered by a whole genome duplication and coincides with global Eocene cooling that continued through the Oligocene and Miocene. The Funariaceae join a growing list of bryophyte lineages whose history is marked by at least one burst of diversification, and our study thereby strengthens the view that bryophytes are evolutionarily dynamic lineages and that patterns and processes characterizing the evolution of angiosperms may be universal among land plants.

New publication on lichens

Robert Lücking and colleagues completed a revision of a complex of lichen species, of which specimens from Chile, are deposited in CONN.

Lücking R., B. Moncada, B. McCune, E. Farkas, B. Goffinet, D. Parker, J. L. Chaves, L. Lőkös, P. R. Nelson, T. Spribille, S. Stenroos, T. Wheeler, A. Yanez-Ayabaca, K. Dillman, O. T. Gockman, T. Goward, J. Hollinger, E. A. Tripp, J. Villella, W. R. Álvaro-Alba, C. Julio Arango, M. E. S. Cáceres, L. Fernando Coca, C. Printzen, C. Rodríguez, K. Scharnagl, R. Rozzi, E. Soto-Medina & L. S. Yakovchenko. 2017. Pseudocyphellaria crocata (Ascomycota: Lobariaceae) in the Americas reveals to be ten species, and none of them is Pseudocyphellaria crocata. The Bryologist 120: 441–500.

Abstract reads: We provide a phylogenetic revision of the Pseudocyphellaria crocata complex in the Americas. Specimens traditionally identified as P. crocata, based on their cyanobacterial photobiont, yellow pseudocyphellae, at least partially white medulla, and yellow soralia or soralia-like structures, are shown to represent 13 distinct species, forming a monophyletic group divided into four large clades, three comprising one species each and one containing eight species, plus two taxa for which no molecular data are available. Seven species correspond to what was previously recognized as P. crocata and one to P. dozyana, whereas a further one is identified as the sorediate counterpart of the usually apotheciate taxon P. lechleri and another as a pseudosorediate morph of the usually phyllidiate species P. neglecta. Surprisingly, none of the species represents P. crocata s.str., which must therefore be excluded from the American lichen biota. The 13 recognized species include three species new to science and three new combinations: P. citrina (Gyeln.) Lücking, Moncada & S.Stenroos, comb. nov. [bas.: Cyanisticta citrina Gyeln., nom. nov. pro Sticta citrina Pers. nom. illeg.], P. desfontainii (Delise) Vain., P. deyi Lücking, sp. nov., P. dozyana (Mont. & Bosch) D.J.Galloway, P. epiflavoides (Gyeln.) Lücking, Farkas & Lokös, comb. nov. [bas.: Cyanisticta epiflavoides Gyeln.], P. hawaiiensis H.Magn., P. hillii (C.W.Dodge) D.J.Galloway, P. holarctica McCune, Lücking & Moncada, sp. nov., P. lechleri (Müll. Arg.) Du Rietz, P. neglecta (Müll. Arg.) H.Magn., P. punctata Lendemer, Lücking & Moncada sp. nov., P. sandwicensis (Zahlbr.) Moncada & Lücking, comb. nov. [bas.: Sticta crocata f. sandwicensis Zahlbr.], and P. xanthosticta (Pers.) Moncada & Lücking. Based on sequenced specimens, a neotype is selected for P. citrina and epitypes for P. hawaiiensis, P. lechleri, P. sandwicensis and P. xanthosticta. A key to all sorediate or pseudosorediate species of this complex in the Americas is presented, and all species are described, discussed and illustrated. pdf
