Bryozoan Studies 2019
BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

Symbiosis and Parasitism in the Crustacea1)
CHAPTER 16 SYMBIOSIS AND PARASITISM IN THE CRUSTACEA1) BY JEAN-PAUL TRILLES AND RÉGINE HIPEAU-JACQUOTTE Contents. – Introduction. Crustaceans as parasites and symbionts – Diversity of the associations encountered – Associations with a permanent or temporary character – The consequences of living in association. The parasites of crustaceans. Appendix. Bibliography. INTRODUCTION Many Crustacea live in some kind of association with other living beings, either animals or plants. In some cases, such a relation would seem the result of accidental, merely occasional encounters: specimens of Volvox, chironomid larvae, and certain ostracodes that are sometimes found in the brood pouch of daphniid Branchiopoda can only be qualified as ‘strays’. For other organisms, in contrast, we can observe true relationships that are often complex and as yet only superficially known. In such cases of true association, quite exact and stringent rules prevail that determine the delicate, yet not infrequently obligate, relationship between the associates at issue. For generations, biologists have attempted to classify those associations into categories. The criterion that was most often applied concerned the exchange, either unilateral or bilateral, between the two associates and included the effects of either profit or harm, even damage. Obviously, teleological and/or anthropomorphic reasoning can easily influence such an approach. The results, thus, were primarily speculative and vague, and the relationships recognized were grossly described as of two types that could relatively easily be determined, i.e., either involving spatial relationships (shelter, protection), or nutritional associations. 1) The original text was updated by Jean-Paul Trilles in May 2008. © Koninklijke Brill NV, Leiden, 2012 Crustacea 3 (16): 239-317 240 J.-P. -
Soil Survey of the United States Virgin Islands
United States In cooperation with Department of the Virgin Islands Agriculture Department of Planning Soil Survey of and Natural Resources; the Natural Virgin Islands Cooperative the United States Resources Extension Service; and the Conservation United States Department Service of Interior, National Park Virgin Islands Service 3 How to Use This Soil Survey General Soil Map The general soil map, which is the color map preceding the detailed soil maps, shows the survey area divided into groups of associated soils called general soil map units. This map is useful in planning the use and management of large areas. To find information about your area of interest, locate that area on the map, identify the name of the map unit in the area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of the soils in your area. Detailed Soil Maps The detailed soil maps follow the general soil map. These maps can be useful in planning the use and management of small areas. To find information about your area of interest, locate that area on the Index to Map Sheets, which precedes the soil maps. Note the number of the map sheet and turn to that sheet. Locate your area of interest on the map sheet. Note the map units symbols that are in that area. Turn to the Contents, which lists the map units by symbol and name and shows the page where each map unit is described. The Contents shows which table has data on a specific land use for each detailed soil map unit. -

Diversity of Epibionts Associated with Lepidochelys Olivacea (Eschscholtz 1829) Sea Turtles Nesting in the Mexican South Pacific

They usually have interspecific relationships of the commensal type; however, some species become parasitic and may cause severe damage, mainly in soft areas. Epibionts provide us with information on the migratory habits of sea turtles and can indicate health status. There are several studies on epibionts and their relationships with sea turtles; however, it is essential to expand research to increase the knowledge that will allow us to comprehend these relationships and their implications.

Epibionts on Brachiopods from the Devonian Dundee Formation of Ohio
EPIBIONTS ON BRACHIOPODS FROM THE DEVONIAN DUNDEE FORMATION OF OHIO Rituparna Bose A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2006 Committee: Margaret M. Yacobucci, Advisor Richard D. Hoare Don C. Steinker © 2006 Rituparna Bose All Rights Reserved iii ABSTRACT Dr. Margaret M. Yacobucci, Advisor Epibionts seem to be more common in siliciclastic units than in carbonate units. To evaluate this difference, the paleontology of the Middle Devonian Dundee Formation has been explored. A total of 245 brachiopod specimens were collected from a fossiliferous horizon of the Dundee Formation exposed at Whitehouse Quarry and identified to the generic level. Brachiopod genera identified were Strophodonta, Rhipidomella, Rhynchotrema, Atrypa, and Mucrospirifer. All the brachiopod shells were examined under a stereomicroscope for evidence of epibionts, and preferred host taxa were determined. Epibionts are absent on all the brachiopod shells except some Rhipidomella shells. Further examination of these Rhipidomella shells under 100x magnification showed evidence of biotic interactions in 21 out of 48 specimens. Large boreholes were produced by worm borers, scars were left on a few specimens by worms, branching grooves were the traces of soft-bodied ctenostome bryozoans, and sheet-like encrustation was produced by an indeterminate group of bryozoans. Ctenostome bryozoans had a commensal relationship with their host while a few worms had a parasitic relation with the host. While one might expect encrustation on hardgrounds within this carbonate unit, field work has determined that much of the Dundee Formation was extensively bioturbated, implying a soft substrate. -

U.S. Virgin Islands Marine Resources and Fisheries Strategic and Comprehensive Conservation Plan 2005 UNITED STATES VIRGIN ISLANDS MARINE RESOURCES AND FISHERIES STRATEGIC AND COMPREHENSIVE CONSERVATION PLAN Division of Fish and Wildlife Department of Planning and Natural Resources U.S. Virgin Islands December 2005 U.S. Virgin Islands ii Marine Resources and Fisheries Strategic and Comprehensive Conservation Plan 2005 EXECUTIVE SUMMARY The US Virgin Islands (USVI) is a territory of the United States. It lies in the northeast Caribbean and consists of four major islands, St. Thomas, St. John, St. Croix, and Water Island, and about 50 cays. The USVI is endowed with many natural resources and contains examples of tropical ecosystems such as coral reefs, seagrass meadows, salt ponds, and mangrove forests. These habitats provide food and shelter for a large variety of resident marine and terrestrial life. In addition, a variety of fish and wildlife migrate through the USVI annually. These natural resources are under pressure from a variety of user groups. The marine waters are heavily fished by both recreational and commercial fishermen. Annually, thousands of tourists visit the USVI to go snorkeling and diving. Pollution is also a primary impact on the marine resources. In addition, economic development such as home and hotel construction continues to infringe on coastal environments. There have been numerous plans completed, at least to draft stage, relating to some aspect of the fisheries and marine resources in the U.S. Virgin Islands (Chapter 1). Plans have been written regarding management of specific areas, topics and issues, and species related to the fisheries and marine resources of the USVI. -
