MPRPD Cover Letter Raskoff August 28, 2019 MPRPD Board of Directors, My name is Kevin Raskoff and I am applying for the open Ward 3 Board of Directors position with the MPRPD. I believe parks offer solitude in an increasingly overwhelming world. They are a place we can meet our friends, exercise our body and mind, and reconnect with the natural world. My goals are to help the Monterey Peninsula Regional Park District increase access and opportunities for our residents and visitors to enjoy, conserve, and support our regional parks. I am a seventeen-year resident of Del Rey Oaks and have lived on the peninsula for 22 years. I am the chair of the biology department at Monterey Peninsula College, having taught at MPC for 13 years full-time. I teach environmental science, marine biology, and ecology and evolution courses. Previous to MPC, I taught full time at CSUMB for three years, and before that was focused on scientific research. I have a Ph.D. from UCLA in Biology and I focused my studies on the ecology of the Monterey deep sea environment. I came to the peninsula in 1997 to work at the Monterey Bay Aquarium Research Institute and did my research fulltime until making the switch to focus on higher education in 2003. Currently, I am also involved with many other groups in the area, including Sustainable Del Rey Oaks, the Monterey Bay National Marine Sanctuary, and the Monterey Academy of Oceanographic Science at Monterey High School. My time in education and research has given me opportunities to understand the natural world and to connect with the professionals who study nature, as well as work with those who are just learning about our local habitats and biodiversity. This experience will allow me to bring an important perspective to the board. I also hope to leverage my experiences in higher education and with the research community to help find new partnerships and opportunities for the MPRPD. Additionally, I want to provide important outreach to my ward and beyond to increase their knowledge of the recreational opportunities. I am eager to learn about what barriers might exist that keep some in the population from greater use of our fantastic park resources. I view the role of the board as both protecting the parks from negative human influences while at the same time doing everything we can to bring more of our residents in to experience what they have to offer. The board serves all the residents of the district and I am anxious to make sure we are reaching out to all individuals so that they can experience the wonders of our regional parks. I hope you will consider my application and I look forward to speaking before the board on September 11th. Please find more information about my background in my CV.

  • Aurelia Japonica: Molecular and Chromosomal Evidence A.V
    Aurelia japonica: molecular and chromosomal evidence A.V. Kotova Institute of Cytology RAS, St. Petersburg, Russia, [email protected] L. S. Adonin Institute of Cytology RAS, St. Petersburg, Russia, [email protected] The genus Aurelia belongs to the family Ulmaridae, order Semaeostomeae, class Scyphozoa, type Cnidaria (Kramp, 1961). Mayer (1910) recorded 13 species of the genus Aurelia, after which Kramp (1961) mentioned only 7 and Russell (1970) reported only 2: A. aurita and A. limbata. At the end of the century again one of the species from «Synopsis of the medusae of the world” (Kramp, 1961), namely A. labiata, came back (Gershwin, 2001). Traditionally, the jellyfish Aurelia aurita was deemed cosmopolitan species. It was reported in a variety of coastal and shelf marine environments between 70°N and 40°S (Kramp, 1961). However, the molecular genetic approach suggests that A. aurita contains 11 cryptic species A.sp.1 – A.sp.11. The name Aurelia aurita was saved to the initial population described by Linnaeus at the European North coast (Dawson, 2001; Dawson, 2003; Dawson et al., 2005). Kishinouye (1891) described a form of Aurelia from Tokyo Bay as Aurelia japonica (Gershwin, 2001). This form of Aurelia was designated Aurelia sp. 1 and considered to be endemic to the western North Pacific and, therefore, dispersed globally from Japan (Dawson et al., 2005). In our previous study, the comparison of structural mesoglea protein mesoglein (Matveev et al., 2007, 2012) and its gene from three habitats White Sea (WsA), Black Sea (BsA), Japonic Sea (JsA) produced clear difference of two Aurelia populations.

  • Life Cycle of Chrysaora Fuscescens (Cnidaria: Scyphozoa) and a Key to Sympatric Ephyrae1
    Life Cycle of Chrysaora fuscescens (Cnidaria: Scyphozoa) and a Key to Sympatric Ephyrae1 Chad L. Widmer2 Abstract: The life cycle of the Northeast Pacific sea nettle, Chrysaora fuscescens Brandt, 1835, is described from gametes to the juvenile medusa stage. In vitro techniques were used to fertilize eggs from field-collected medusae. Ciliated plan- ula larvae swam, settled, and metamorphosed into scyphistomae. Scyphistomae reproduced asexually through podocysts and produced ephyrae by undergoing strobilation. The benthic life history stages of C. fuscescens are compared with benthic life stages of two sympatric species, and a key to sympatric scyphome- dusa ephyrae is included. All observations were based on specimens maintained at the Monterey Bay Aquarium jelly laboratory, Monterey, California. The Northeast Pacific sea nettle, Chry- tained at the Monterey Bay Aquarium, Mon- saora fuscescens Brandt, 1835, ranges from terey, California, for over a decade, with Mexico to British Columbia and generally ap- cultures started by F.

    AMERICAN MUSEUM NOVITATES Number 3900, 14 pp. May 9, 2018 In situ Observations of the Meso-Bathypelagic Scyphozoan, Deepstaria enigmatica (Semaeostomeae: Ulmaridae) DAVID F. GRUBER,1, 2, 3 BRENNAN T. PHILLIPS,4 LEIGH MARSH,5 AND JOHN S. SPARKS2, 6 ABSTRACT Deepstaria enigmatica (Semaeostomeae: Ulmaridae) is one of the largest and most mysteri- ous invertebrate predators of the deep sea. Humans have encountered this jellyfish on only a few occasions and many questions related to its biology, distribution, diet, environmental toler- ances, and behavior remain unanswered. In the 45 years since its formal description, there have been few recorded observations of D. enigmatica, due to the challenging nature of encountering these delicate soft-bodied organisms. Members ofDeepstaria , which comprises two described species, D. enigmatica and D. reticulum, reside in the meso-bathypelagic region of the world’s oceans, at depths ranging from ~600 to 1750 m. Here we report observations of a large D. enigmatica (68.3 cm length × 55.7 cm diameter) using a custom color high-definition low-light imaging system mounted on a scientific remotely operated vehicle (ROV). Observations were made of a specimen capturing or “bagging” prey, and we report on the kinetics of the closing motion of its membranelike umbrella. In the same area, we also noted a Deepstaria “jelly-fall” carcass with a high density of crustaceans feeding on its tissue and surrounding the carcass. These observations provide direct evidence of singular Deepstaria carcasses acting as jelly falls, which only recently have been reported to be a significant food source in the deep sea.

LINDSAY 1 School of Marine Bioscience, Kitasato University, Sagamihara, Kanagawa, Japan 2 Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka, Kanagawa, Japan Received 8 November 2017; Accepted 25 January 2018 Responsible Editor: Jun Nishikawa Abstract: An individual narcomedusa assignable to Solmissus incisa sensu lato was observed having ingested a fish at 573 m depth near the southeast slope of the Kaikata seamount, Japan. Solmissus is a very common deep-sea narco- medusan genus that is widely considered to be a predator specializing on gelatinous plankton. Several cryptic species, with differences in the number of tentacles and form of manubrial pouches, are thought to be included in the nominal species Solmissus incisa. Therefore, the present study gives a short description of the morphotype of Solmissus incisa s.l. observed with a fish in its stomach, as well as several individuals of the same morphotype that had ingested gelati- nous prey.

Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.
