  • Morphometric Analysis of Surface Utricles in Halimeda Tuna (Bryopsidales, Ulvophyceae) Reveals Variation in Their Size and Symmetry Within Individual Segments
    S S symmetry Article Morphometric Analysis of Surface Utricles in Halimeda tuna (Bryopsidales, Ulvophyceae) Reveals Variation in Their Size and Symmetry within Individual Segments Jiri Neustupa * and Yvonne Nemcova Department of Botany, Faculty of Science, Charles University, Prague, 12801 Benatska 2, Czech Republic; [email protected] * Correspondence: [email protected] Received: 26 June 2020; Accepted: 20 July 2020; Published: 1 August 2020 Abstract: Calcifying marine green algae of genus Halimeda have siphonous thalli composed of repeated segments. Their outer surface is formed by laterally appressed peripheral utricles which often form a honeycomb structure, typically with varying degrees of asymmetry in the individual polygons. This study is focused on a morphometric analysis of the size and symmetry of these polygons in Mediterranean H. tuna. Asymmetry of surface utricles is studied using a continuous symmetry measure quantifying the deviation of polygons from perfect symmetry. In addition, the segment shapes are also captured by geometric morphometrics and compared to the utricle parameters. The area of surface utricles is proved to be strongly related to their position on segments, where utricles near the segment bases are considerably smaller than those located near the apical and lateral margins. Interestingly, this gradient is most pronounced in relatively large reniform segments. The polygons are most symmetric in the central parts of segments, with asymmetry uniformly increasing towards the segment margins. Mean utricle asymmetry is found to be unrelated to segment shapes. Systematic differences in utricle size across different positions might be related to morphogenetic patterns of segment development, and may also indicate possible small-scale variations in CaCO3 content within segments.

    Integrative Biology 200 "PRINCIPLES OF PHYLOGENETICS" Spring 2018 University of California, Berkeley B.D. Mishler March 14, 2018. Classification II: Phylogenetic taxonomy including incorporation of fossils; PhyloCode I. Phylogenetic Taxonomy - the argument for rank-free classification A number of recent calls have been made for the reformation of the Linnaean hierarchy (e.g., De Queiroz & Gauthier, 1992). These authors have emphasized that the existing system is based in a non-evolutionary world-view; the roots of the Linnaean hierarchy are in a specially- created world-view. Perhaps the idea of fixed, comparable ranks made some sense under that view, but under an evolutionary world view they don't make sense. There are several problems with the current nomenclatorial system: 1. The current system, with its single type for a name, cannot be used to precisely name a clade. E.g., you may name a family based on a certain type specimen, and even if you were clear about what node you meant to name in your original publication, the exact phylogenetic application of your name would not be clear subsequently, after new clades are added. 2. There are not nearly enough ranks to name the thousands of levels of monophyletic groups in the tree of life. Therefore people are increasingly using informal rank-free names for higher- level nodes, but without any clear, formal specification of what clade is meant. 3. Most aspects of the current code, including priority, revolve around the ranks, which leads to instability of usage. For example, when a change in relationships is discovered, several names often need to be changed to adjust, including those of groups whose circumscription has not changed.

    A survey of fishes associated with Hawaiian deep-water Halimeda kanaloana (Bryopsidales: Halimedaceae) and Avrainvillea sp. (Bryopsidales: Udoteaceae) meadows Ross C. Langston1 and Heather L. Spalding2 1 Department of Natural Sciences, University of Hawai`i- Windward Community College, Kane`ohe,¯ HI, USA 2 Department of Botany, University of Hawai`i at Manoa,¯ Honolulu, HI, USA ABSTRACT The invasive macroalgal species Avrainvillea sp. and native species Halimeda kanaloana form expansive meadows that extend to depths of 80 m or more in the waters off of O`ahu and Maui, respectively. Despite their wide depth distribution, comparatively little is known about the biota associated with these macroalgal species. Our primary goals were to provide baseline information on the fish fauna associated with these deep-water macroalgal meadows and to compare the abundance and diversity of fishes between the meadow interior and sandy perimeters. Because both species form structurally complex three-dimensional canopies, we hypothesized that they would support a greater abundance and diversity of fishes when compared to surrounding sandy areas. We surveyed the fish fauna associated with these meadows using visual surveys and collections made with clove-oil anesthetic. Using these techniques, we recorded a total of 49 species from 25 families for H. kanaloana meadows and surrounding sandy areas, and 28 species from 19 families for Avrainvillea sp. habitats. Percent endemism was 28.6% and 10.7%, respectively. Wrasses (Family Labridae) were the most speciose taxon in both habitats (11 and six species, respectively), followed by gobies for H. kanaloana (six Submitted 18 November 2016 species). The wrasse Oxycheilinus bimaculatus and cardinalfish Apogonichthys perdix Accepted 13 April 2017 were the most frequently-occurring species within the H.

An assemblage of calcareous algae (dasycladaleans and halimedaceans) is described from the Upper Cenomanian to Lower Turonian of the Galala and Maghra el Hadida formations (Wadi Araba, northern Eastern Desert, Egypt). The following taxa have been identified: Dissocladella sp., Neomeris mokragorensis RADOIČIĆ & SCHLAGINTWEIT, 2007, Salpingoporella milovanovici RADOIČIĆ, 1978, Trinocladus divnae RADOIČIĆ, 2006, Trinocladus cf. radoicicae ELLIOTT, 1968, and Halimeda cf. elliotti CONARD & RIOULT, 1977. Most of the species are recorded for the first time from Egypt. Three of the identified algae (T. divnae, S. milovanovici and H. elliotti) also occur in Cenomanian limestones of the Mirdita zone, Serbia, suggesting a trans-Tethyan distribution of these taxa during the early Late Cretaceous. The abundance and preservation of the algae suggest an autochthonous occurrence which can be used to characterize the depositional environment. The recorded calcareous algae as well as the sedimentologic and palaeontologic context of the Galala Formation support an open-lagoonal (non-restricted), warm-water setting. The Maghra el Hadida Formation was mainly deposited in a somewhat deeper, open shelf setting.

  • An Annotated List of Marine Chlorophyta from the Pacific Coast of the Republic of Panama with a Comparison to Caribbean Panama Species
    Nova Hedwigia 78 1•2 209•241 Stuttgart, February 2004 An annotated list of marine Chlorophyta from the Pacific Coast of the Republic of Panama with a comparison to Caribbean Panama species by Brian Wysor The University of Louisiana at Lafayette, Department of Biology PO Box 42451, Lafayette, LA 70504-2451, USA. Present address: Bigelow Laboratory for Ocean Sciences PO Box 475, McKown Point, West Boothbay Harbor, ME 04575, USA. With 21 figures, 3 tables and 1 appendix Wysor, B. (2004): An annotated list of marine Chlorophytafrom the Pacific Coast of the Republic of Panama with a comparison to Caribbean Panama species. - Nova Hedwigia 78: 209-241. Abstract: Recent study of marine macroalgal diversity of the Republic of Panama has led to a substantial increase in the number of seaweed species documented for the country. In this updated list of marine algae based on collections made in 1999 and reports from the literature, 44 Chlorophyta (43 species and one variety) are documented for the Pacific coast of Panama, including 27 new records. A comparison of chlorophyte diversity along Caribbean and Pacific coasts revealed greater diversity at nearly all taxonomic levels in the Caribbean flora. Differences in environmentalregime (e.g., absence of sea grasses, lower abundance and diversity of hermatypic corals, and greater tidal range along the Pacific coast) explained some of the discrepancy in diversity across the isthmus. Fifteen taxa were common to Caribbean and Pacific coasts, but the number of amphi-isthmian taxa nearly doubled when taxa from nearby floras were includedin the estimate. These taxa may represent daughter populations of a formerly contiguouspopulation that was severed by the emerging Central American Isthmus.
