PENNSYLVANIA ACADEMY OF SCIENCE MINUTES OF THE 1936 SUMMER MEETING August 14 and 15 Somerset, Pennsylvania Members of the Academy and friends gathered at Somerset in the afternoon of August 14 and formed two groups. One group traveled to the virgin hemlock forest near Bucktown on U. S. Route 30, while the other group studied the rock formations and the gorge of Cas1;1elman River. In the evening, after dinner at the Ferner Hotel, the following pro­ gram was enjoyed by about 30 persons; The physiographic significance of N eg1·o Mountain. R. W. Stone, Pennsylvania Geological Survey. The forest, its trees, trails and tourists. V. M. Bearer, District Forester, Ligonier: The fiom of Negro Mmmtain. President Paul R. Stewart, Waynes­ burg College. Sorne notable plants of sottth-central Pennsylvania. Dr. Edgar T. Wherry, University of Pennsylvania. Snakes in Somerset County. M. Graham Netting, Carnegie Museum. A business meeting followed in which a grant of $125.00 for research from the American Association for the Advancement of Science was awarded to Raymond J. Greb and his wife Magnhild Torvik-Greb of the Research Laboratories of the Pittsburgh Skin and Cancer Foundation for research on Further Studies on the Unstable Gene in Habrobracon. The library committee was instructed to distribute the Proceedings which the editor reported about ready for mailing. Dr. Bradford Willard, press secretary, reported sending·notices to the local newspapers telling them of the various activities of the Academy. Dr. Karl F. Oerlein, represe:i).ting the Junior Academy, reported that he was getting out a pamphlet· concerning the activities of the Junior Academy which will be sent to all high schools in the State. A motion sponsored by M. Graham Netting that the Academy urge that the stand of virgin hemlock at Bucktown in Somerset County be made a State Forest Preserve, was adopted. A conservation committee composed of: M. Graham Netting, Chair­ man, Edgar T. Wherry, D. S. Hartline, J. Kenneth Terres, and E. M. Gress was appointed by the president Dr. T. D. Cope.

  • Divergence Time Estimates and the Evolution of Major Lineages in The
    www.nature.com/scientificreports OPEN Divergence time estimates and the evolution of major lineages in the florideophyte red algae Received: 31 March 2015 Eun Chan Yang1,2, Sung Min Boo3, Debashish Bhattacharya4, Gary W. Saunders5, Accepted: 19 January 2016 Andrew H. Knoll6, Suzanne Fredericq7, Louis Graf8 & Hwan Su Yoon8 Published: 19 February 2016 The Florideophyceae is the most abundant and taxonomically diverse class of red algae (Rhodophyta). However, many aspects of the systematics and divergence times of the group remain unresolved. Using a seven-gene concatenated dataset (nuclear EF2, LSU and SSU rRNAs, mitochondrial cox1, and plastid rbcL, psaA and psbA genes), we generated a robust phylogeny of red algae to provide an evolutionary timeline for florideophyte diversification. Our relaxed molecular clock analysis suggests that the Florideophyceae diverged approximately 943 (817–1,049) million years ago (Ma). The major divergences in this class involved the emergence of Hildenbrandiophycidae [ca. 781 (681–879) Ma], Nemaliophycidae [ca. 661 (597–736) Ma], Corallinophycidae [ca. 579 (543–617) Ma], and the split of Ahnfeltiophycidae and Rhodymeniophycidae [ca. 508 (442–580) Ma]. Within these clades, extant diversity reflects largely Phanerozoic diversification. Divergences within Florideophyceae were accompanied by evolutionary changes in the carposporophyte stage, leading to a successful strategy for maximizing spore production from each fertilization event. Our research provides robust estimates for the divergence times of major lineages within the Florideophyceae. This timeline was used to interpret the emergence of key morphological innovations that characterize these multicellular red algae. The Florideophyceae is the most taxon-rich red algal class, comprising 95% (6,752) of currently described species of Rhodophyta1 and possibly containing many more cryptic taxa2.

Detailed data on bacterial and protistan microfossils are presented from a 0.003 mm3 piece of Triassic amber (Schlier- seerit, Upper Triassic period, 220-230 million years old). This microcenosis, which actually existed as such within a very small, probably semiaquatic habitat, included the remains of about two bacteria species, four fungi (Palaeodikaryomyces baueri, Pithomyces-like conidia, capillitium-like hyphae, yeast cells) two euglenoids, two chlamydomonas (Chlamydomonas sp., Chloromonas sp.), two coccal green microalgae (Chlorellu sp., Chorzcystis-like cells), one zooflagellate, three testate amoebae (Centropyxis aculeata var. oblonga-like, Cyclopyxis eurystoma-like, Hyalosphenia baueri n. sp.), seven ciliates (Pseudoplatyophrya nana-like, Mykophagophrys rerricola-like, Cvrtolophosis mucicola-like, Paracondylostoma
