  • Section 3.4 Biological Resources 3.4- Biological Resources
    SECTION 3.4 BIOLOGICAL RESOURCES 3.4- BIOLOGICAL RESOURCES 3.4 BIOLOGICAL RESOURCES This section discusses the existing sensitive biological resources of the San Francisco Bay Estuary (the Estuary) that could be affected by project-related construction and locally increased levels of boating use, identifies potential impacts to those resources, and recommends mitigation strategies to reduce or eliminate those impacts. The Initial Study for this project identified potentially significant impacts on shorebirds and rafting waterbirds, marine mammals (harbor seals), and wetlands habitats and species. The potential for spread of invasive species also was identified as a possible impact. 3.4.1 BIOLOGICAL RESOURCES SETTING HABITATS WITHIN AND AROUND SAN FRANCISCO ESTUARY The vegetation and wildlife of bayland environments varies among geographic subregions in the bay (Figure 3.4-1), and also with the predominant land uses: urban (commercial, residential, industrial/port), urban/wildland interface, rural, and agricultural. For the purposes of discussion of biological resources, the Estuary is divided into Suisun Bay, San Pablo Bay, Central San Francisco Bay, and South San Francisco Bay (See Figure 3.4-2). The general landscape structure of the Estuary’s vegetation and habitats within the geographic scope of the WT is described below. URBAN SHORELINES Urban shorelines in the San Francisco Estuary are generally formed by artificial fill and structures armored with revetments, seawalls, rip-rap, pilings, and other structures. Waterways and embayments adjacent to urban shores are often dredged. With some important exceptions, tidal wetland vegetation and habitats adjacent to urban shores are often formed on steep slopes, and are relatively recently formed (historic infilled sediment) in narrow strips.

OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig.

Canine teeth collected during the last 2 decades from 45 dead monk seals inhabiting Greek waters were processed for age estimation. Ages were best estimated by counting growth layer groups (GLGs) in the cementum adjacent to the root tip using un - processed longitudinal or transverse sections (360 µm thickness) observed under polarized light. Decalcified and stained thin sections (8 to 23 µm) of both cementum and dentine were inferior to unprocessed sections. From analysing patterns of deposition in the cementum of known age- maturity class individuals, one GLG was found to be deposited annually in M.

  • Collagen Fingerprinting and the Earliest Marine Mammal Hunting in North America Received: 2 February 2018 Courtney A
    www.nature.com/scientificreports OPEN Collagen Fingerprinting and the Earliest Marine Mammal Hunting in North America Received: 2 February 2018 Courtney A. Hofman 1,2, Torben C. Rick3, Jon M. Erlandson4, Leslie Reeder-Myers5, Accepted: 18 June 2018 Andreanna J. Welch6,2 & Michael Buckley 7 Published: xx xx xxxx The submersion of Late Pleistocene shorelines and poor organic preservation at many early archaeological sites obscure the earliest efects of humans on coastal resources in the Americas. We used collagen fngerprinting to identify bone fragments from middens at four California Channel Island sites that are among the oldest coastal sites in the Americas (~12,500-8,500 cal BP). We document Paleocoastal human predation of at least three marine mammal families/species, including northern elephant seals (Mirounga angustirostris), eared seals (Otariidae), and sea otters (Enhydra lutris). Otariids and elephant seals are abundant today along the Pacifc Coast of North America, but elephant seals are rare in late Holocene (<1500 cal BP) archaeological sites. Our data support the hypotheses that: (1) marine mammals helped fuel the peopling of the Americas; (2) humans afected marine mammal biogeography millennia before the devastation caused by the historic fur and oil trade; and (3) the current abundance and distribution of recovering pinniped populations on the California Channel Islands may mirror a pre-human baseline. Recent archaeological, genomic, and paleoecological research identifes the Pacifc Coast as one of the gateways for the peopling of the Americas1–8. California’s Channel Islands fgure prominently in this research with ~13,000- 11,000 year old sites that contain human remains, sophisticated hunting tools, and diverse faunal assemblages3,9,10.

  • What Do You Do When a Northern Elephant Seal Visits Your Beach?
    Summer 2019 Island County, WA Issue No. 124 By Darcy McNamara, Extension Coordinator, Jefferson County Extension and Bob Simmons, Associate Professor, WSU Extension. Special thanks to Joanne for sharing her story and to Betsy Carlson, Port Townsend Marine Science Center. What do you do when a northern elephant seal visits your beach? This female northern elephant seal was recovering from injuries when it showed up at Joanne's house. Photo by Joanne. Joanne had a big surprise waiting when she returned home one afternoon in July. There was something on her beach. At first, she thought it was just a large seal, but as a recent graduate of WSU’s Beach Naturalist class and a trained “seal sitter,” something about it was different. Looking through binoculars she saw it had black whiskers, small fore flippers, and no external ear flaps (making it a true seal). But the size was what gave the visitor’s identity away. It was a northern elephant seal (Mirounga angustirostris) – the largest true seal in the northern hemisphere. Females grow up to 10 feet long and weigh up to 1,300 pounds and males can even grow larger, reaching 13 feet long and 4,000 pounds. The seal resting on the beach in July. Photo by Joanne. Joanne contacted Betsy Carlson, Citizen Science Coordinator for the Port Townsend Marine Science Center and learned that a badly injured female northern elephant seal had been seen on a nearby Olympic Peninsula beach in April. The seal in front of Joanne’s home had some scars and they determined it was probably the same animal.

  • First Record of a Galapagos Fur Seal (Arctocephalus Galapagoensis) In
    Quintana-Rizzo et al. Marine Biodiversity Records (2017) 10:24 DOI 10.1186/s41200-017-0126-x MARINERECORD Open Access First record of a Galapagos fur seal (Arctocephalus galapagoensis) in Guatemala Ester Quintana-Rizzo1,4* , Lucia Garcia2, Rudy José López1, Susana Tobar-Hurtado3,5 and Airam López-Roulet1 Abstract Background: Galapagos fur seals, Arctocephalus galapagoensis, inhabit the Galapagos Archipelago. The species is considered to be non-migratory, remaining in the Galapagos year-round. On 9 June 2016, a live fur seal stranded on the Pacific coast of Guatemala. Results: Morphological characteristics (slightly rounded crown, short pointed muzzle with a lighter colored pelage extending into the face and over the eyes forming a small pale mask, tan ventrum contrasting with grizzled gray-brown fur on the back and sides) were used to identify the pinniped as a Galapagos fur seal, Arctocephalus galapagoensis. Additionally, the fur seal was estimated to be a subadult male based on body size and the presence of testicles. Total body length was estimated to be 140 cm and the weight was estimated to be 90 lb. For comparison, adult males of A. galapagoensis measured to date are slightly larger with an average length and weight equal to 150–160 cm and 132–150 lb., respectively. The species identification and age-class determination were confirmed by pinniped specialists. Conclusion: This is the first record of Galapagos fur seal in the Pacific coast of Guatemala and in the Central America region. Keywords: Arctocephalus galapagoensis, Galapagos fur seal, Guatemala, Stranding Background In the Americas, the distribution of Arctocephalus is The marine mammal fauna of Guatemala is comprised of limited to four species inhabiting localized areas: A.
