Closer inspection of the bands reveals unusual ciliary \tangles" analogous to topological defects that break-up and re-form as the animal adjusts its swimming stroke. Quantitative experiments and modeling demonstrate that these vortices create a physical tradeoff between feeding and swim- ming in heterogenous environments, which manifests as distinct flow patterns or \eigen- strokes" representing each behavior|potentially implicating neuronal control of cilia. This quantitative interplay between larval form and hydrodynamic function may gen- eralize to other invertebrates with ciliary bands, and illustrates the potential

  • Systematic Comparison of Sea Urchin and Sea Star Developmental Gene Regulatory Networks Explains How Novelty Is Incorporated in Early Development
    ARTICLE https://doi.org/10.1038/s41467-020-20023-4 OPEN Systematic comparison of sea urchin and sea star developmental gene regulatory networks explains how novelty is incorporated in early development Gregory A. Cary 1,3,5, Brenna S. McCauley1,4,5, Olga Zueva1, Joseph Pattinato1, William Longabaugh2 & ✉ Veronica F. Hinman 1 1234567890():,; The extensive array of morphological diversity among animal taxa represents the product of millions of years of evolution. Morphology is the output of development, therefore phenotypic evolution arises from changes to the topology of the gene regulatory networks (GRNs) that control the highly coordinated process of embryogenesis. A particular challenge in under- standing the origins of animal diversity lies in determining how GRNs incorporate novelty while preserving the overall stability of the network, and hence, embryonic viability. Here we assemble a comprehensive GRN for endomesoderm specification in the sea star from zygote through gastrulation that corresponds to the GRN for sea urchin development of equivalent territories and stages. Comparison of the GRNs identifies how novelty is incorporated in early development. We show how the GRN is resilient to the introduction of a transcription factor, pmar1, the inclusion of which leads to a switch between two stable modes of Delta-Notch signaling. Signaling pathways can function in multiple modes and we propose that GRN changes that lead to switches between modes may be a common evolutionary mechanism for changes in embryogenesis. Our data additionally proposes a model in which evolutionarily conserved network motifs, or kernels, may function throughout development to stabilize these signaling transitions. 1 Department of Biological Sciences, Carnegie Mellon University, Pittsburgh, PA 15213, USA.

  • Variation in Blade Morphology of the Kelp Eisenia Arborea: Incipient Speciation Due to Local Water Motion?
    MARINE ECOLOGY PROGRESS SERIES Vol. 282: 115–128, 2004 Published November 16 Mar Ecol Prog Ser Variation in blade morphology of the kelp Eisenia arborea: incipient speciation due to local water motion? Loretta M. Roberson1, 3,* James A. Coyer2 1Hopkins Marine Station, Stanford University, Pacific Grove, California 93950, USA 2Department of Marine Biology, University of Groningen, Kerklaan 30, PO Box 14, 9750 AA Haren, The Netherlands 3Present address: Institute of Neurobiology and Department of Biology, University of Puerto Rico, PO Box 23360, San Juan, Puerto Rico 00931-3360, USA ABSTRACT: The southern sea palm kelp Eisenia arborea produces wide, bullate (bumpy) blades in low-flow areas, whereas in adjacent high-flow areas blades are flat and narrow. Here we determine if morphological differences in these 2 closely associated populations are correlated with physical factors in the environment, and whether this response is a genetically fixed or plastic trait. Both phe- notypes were subjected to morphometric analysis, field and laboratory transplant experiments, and genetic analysis (M13 DNA fingerprinting). Physical variables (water motion, temperature, and light) were monitored simultaneously in the field. Results indicate that the 2 populations, separated by <10m, are genetically distinct and transplants in the field and lab remained similar to individuals from the original collection location, regardless of the imposed flow environment. Water motion var- ied significantly between the 2 populations and was the single physical variable that correlated with morphology. Based on bump heights and water velocities in the field, bullate blades could increase turbulent transport of nutrients 4-fold that of flat blades. The thicker blades and large holdfasts of the flat morph may impart higher survivorship under high-flow conditions.

  • The Effect of Wave Exposure on the Morphology of Ecklonia Radiata
    Aquatic Botany 83 (2005) 61–70 www.elsevier.com/locate/aquabot The effect of wave exposure on the morphology of Ecklonia radiata Thomas Wernberg a,*, Mads S. Thomsen b a School of Plant Biology, Botany Building MO90, University of Western Australia, Crawley, 6009 WA, Australia b Department of Applied Sciences, Auckland University of Technology, Auckland, New Zealand Received 3 August 2004; received in revised form 11 April 2005; accepted 31 May 2005 Abstract This study examined the consistency of the effect of wave exposure on the morphology of Ecklonia radiata, a small kelp, across a broad geographic range (>1100 km). Fifteen morphological characters were measured on individuals from sites of low (2.5 Æ 0.8 S.E.) and high (12.2 Æ 2.0 S.E.) wave exposure (Baardseth’s index) within six locations in southwestern Australia. With the exception of lateral width (P = 0.0001), none of the morphological characters were consistently statistically different (P > 0.06) between high and low wave exposure and correlations with wave exposure were generally weak (r < 0.60). While 12 of the 15 characters were statistically different (P < 0.008) between sites of different exposure within at least one location, the direction of difference (significant or not) was opposite between some locations for all but one character (lateral width). ANOSIM was not able to separate thalli from high and low exposure when all locations were pooled (Clarke’s R = 0.127), but within each location most sites showed better separation (0.126 < Clarke’s R < 0.829). Despite the lack of statistical differences, trends suggested that E.

Abstract: The present report presents the surveys of marine flora 2013 – 2014 in the San Ignacio Lagoon of the, representing the 50% of planned visits and in where we were able to identifying 19 species of macroalgae to the area plus 2 Seagrass traditionally cited. The analysis of the number of species / distribution of macroalgae and seagrass is in progress using an intense review of literature who will be concluded using the last field trip information in May-June 2014. During the last two years we have not been able to find large abundances of species of microalgae as were described since 2006 and the floristic lists developed in the 90's. This added with the presence to increase both coverage and biomass of invasive species which makes a real threat to consider.

  • Turf Assemblage of a Macrocystis Kelp Forest: Experiments On
    AN ABSTRACT OF THE THESIS OF A. Keith Miles for the degree of Doctor of Philosophy in Wildlife Science presented on June 16. 1986. Title: A m Macrosti t° Ex nmen n and Herbivory. Redacted for privacy Abstract approved: E. Charles Meslow Early and later successional stages of the assemblage of turf algae and sessile animals of a Macrocystis kelp forest were studied off San Nicolas Island, California from 1980 through 1981, and 1983 through 1984. Kelps were manipulated to determine if differences in illumination could account for dominance by turf algae or sessile animals. Caging and algal-removal experiments were conducted to determine if the effects of herbivory and competition could account for the low or variable recruitment and abundance of foliose turf algae. Plots were covered for different time intervals up to 1 year to determine if survival of overgrowth could explain the prevalence of competitively subordinate crustose coralline algae. Increased cover and recruitment of turf algae and decreased cover and low recruitment of sessile animals were correlated with the removal of canopy. In the presence of canopy, existing cover of crustose algae and sessile animalschanged little over time; sessile animals recruited at significantly higher levels thanalgae on cleared plots. Patiria (a common invertebrate grazer) removed certain ephemeral algae and appeared to slow recruitment by other algae, but had little effect on mature turf algae. These effects appeared dependent on a high density of Patiria. Algal recruitment on caged and open, near-bare plots was negligible, but sessile animals recruited heavily to these plots. These results were correlated with low illumination caused by a dense and persistent surface canopy of Macrocystis.

MOLLUSCA: LORICA T A, LAMELLIBRANCHIA T A, AND GASTROPODA By L. R. Fisher, S. K. Kon and S. Y. Thompson National Institute for Research in Dairying, University of Reading INTRODUCTION Apart from a general account (Kon, 1954) of our work on vitamin A and carotenoids in invertebrates, our publications so far (Kon & Thompson, 1949a, b; Batham, Fisher, Henry, Kon & Thompson, 1951; Fisher, Kon & Thompson, 1951, 1952, 1953, 1954, 1955) have been concerned only with marine Crustacea. We have also studied, during our investigation of the metabolism of vitamin A and its possible precursors in the sea, numerous species from most other phyla of marine invertebrates. Except for the nematode worm, Anisakis physeteris Baylis, taken from the stomach of a sperm whale, the only two phyla of invertebrate animals in which we have so far found vitamin A are the Arthropoda and the Mollusca, The vitamin was present in at least some species from each of the molluscan classes, Loricata, Gastropoda, Lamellibranchiata and Cephalopoda, but we have no informa- tion yet about the Solenogastres or the Scaphopoda of which we have analysed no representatives. So far as our studies were concerned, the cephalopods differed considerably from the other molluscs examined, and the relatively large amount of information they have provided will be more conveniently presented in a subsequent paper. The account which follows, therefore, deals only with species from the first three classes just listed.
