South Georgia and Antarctic Peninsula Earth’S Greatest Wildlife Destination October 21 to November 12, 2021 South Georgia and Antarctic Peninsula Earth’s Greatest Wildlife Destination October 21 to November 12, 2021 King Penguins, South Georgia Island © Scott Davis SAFARI OVERVIEW Experience the vibrant spring of South Georgia Island and the early season of the Antarctic Peninsula. Beneath the towering, snow-blanketed mountains of South Georgia Island, observe and photograph special wildlife behaviors seldom seen. This time of year is the only time you can find southern elephant seal bulls fight for territories while females nurse young, distinctly marked gray-headed albatross attending to their cliffside nests, and awkward wandering albatross young attempting first flight. You’ll stand amongst vast colonies of king penguins and watch macaroni penguins launching into the ocean. This time of year, the Antarctic Peninsula is in the beginnings of its spring season when the ice in the Weddell Sea can open up, allowing opportunities for lone emperor penguins to wander on ice floes. At penguin colonies, you’ll find penguins courting, setting up nests, and perhaps laying eggs. Through over twenty-five years of experience in the Antarctic, we offer the most in-depth exploration of one of the densest wildlife spectacles found anywhere in the world, and with only 100 passengers, you’ll have ample opportunities to experience this spectacle during every landing and Zodiac cruise. Cheesemans’ Ecology Safaris Page 1 of 19 Updated: March 2021 HIGHLIGHTS • Spend six full days on South Georgia Island and six full days in the Antarctic Peninsula and South Shetland Islands with maximum shore time and Zodiac cruising. • See five penguin species (possibly 6)! Plus, many species of whales, seals, albatross, and seabirds. • Hear the cacophony of and smell king penguins as you walk near colonies of up to 300,000 birds. • See gentoo, macaroni, chinstrap, and Adelie penguins as they start their breeding cycles. • Marvel at dramatic snow-capped mountains descending into valleys and glacier-fed rivers emptying into the ocean. • Watch southern elephant seal bulls defend their territories from competing bulls and females nursing pups during their peak breeding season. • See wandering albatross chicks and endangered gray-headed albatross on nests, only possible this time of year. • Hike or snowshoe on South Georgia Island. Take shorter walks in the Antarctic Peninsula. • With only 100 participants, everyone can land and/or Zodiac cruise at once, rather than in separate groups. • Our 15 leaders are polar specialists, photographers, and naturalists who will provide lectures, workshops, and guided excursions. LEADERS: Ted Cheeseman assisted by 14 other leaders. DAYS: 23, including estimated travel time. 19 nights aboard the Plancius. GROUP SIZE: 100. With only 100 participants, everyone can land and/or Zodiac cruise at once, rather than in separate groups, giving you more time on shore. SHIP: The Plancius. See the Ship section on page 7.

  • An Expedition to the Remote Islands of the South Atlantic South Georgia – Tristan Da Cunha – St
    An Expedition to the remote islands of the South Atlantic South Georgia – Tristan da Cunha – St. Helena Our ship m/v Plancius has spent the winter season, "The Austral summer", in Antarctica and turns north in March to sail in the Arctic during the summer season. We are guests aboard her voyage between the hemispheres. Our voyage takes us to three of the Atlantic's most inaccessible island groups and islands: South Georgia, Tristan da Cunha and St. Helena. Tristan da Cunha is the world's most solitary island community and furthest away from any mainland. The expedition is led by Captain Torbjörn Svensson, who has visited all the islands on many occasions. Torbjörn is the son of the Swedish author and artist Roland Svensson, who himself made repeated long stays at Tristan and St. Helena. The memory of Roland lives on and the islanders on Tristan and St. Helena will receive us as their friends. Tour guide and lecturer: Captain Torbjörn Svensson is the son of Roland Svensson, who in his time wrote among other the classics, “Lonely Isles” on the Hebrides, Orkney and Shetland islands and “Archipelago Life in days gone by” on the Stockholm world of islands. Through his father, Torbjörn has a strong connection to the islands and he looks forward to introducing us to his friends on Tristan da Cunha. Torbjörn has visited Tristan and St. Helena as commander of cruise expedition vessels and he has made several visits to South Georgia, the Antarctic Peninsula and Ushuaia. Torbjörn's life has largely been about seafaring.

    8 days South Georgia Special incl. Steeple Jason, Carcass Island, Falkland Islands - Birding Experience the best of the sub-Antarctic Title: 8 days South Georgia Special incl. Steeple Jason, Carcass Island, Falkland Islands - Birding Dates: 5 Nov - 25 Nov, 2021 Tripcode: JNS21-21 Duration: 20 nights Ship: m/v Janssonius Embarkation: Puerto Madryn Disembarkation: Ushuaia Language: English speaking voyage ITINERARY PLEASE NOTE: All itineraries are for guidance only. Programs may vary depending on local ice and weather conditions and in order to take advantage of opportunities to see wildlife. The on-board expedition leader determines the final itinerary. Itineraries may mention places that require permission to land, which must be granted by the relevant national authorities. Such permission is not granted prior to the publishing of these itineraries. Flexibility is paramount for expedition cruises. Average cruising speed of m/v Janssonius is 10,5 knots. Few places compare to South Georgia in terms of exotic wildlife and jaw-dropping scenery, and the Falklands are no different. On this exploratory voyage you can enjoy both, possibly touring the world’s largest black-browed albatross colony while also seeing some of the biggest breeding spots for king penguins and elephant seals on Earth – along with day after day of amazing polar scenery. Birding: - We will have at least one dedicated expedition guide in our team who will share their expert knowledge about bird species and who will be available to help you identify, photograph on deck and learn more about the birds that we see. In addition to outdoor sessions, our guide will focus on species and related information on the birds of the Antarctic in re-caps and lectures onboard.

  • In the Wake of Penguins
    In the Wake of Penguins The route/purpose of this 5 week expedition is the extraordinary chance to see far flung corners of the South Atlantic. We will be leaving from Puerto Madryn, a coastal town in picturesque Patagonia. Our aim is to reach South Georgia, an island positioned in the South Atlantic about 800 nm to the south east of the Falklands. It is true oasis set in the chilly waters surrounding the Antarctic continent. Millions of penguins, seals and elephant seals live in this harsh environment, hundreds of miles from civilization. The expedition is a real challenge for sailors - to this day, very few have reached there. It is an incredible chance to see nature at its wildest and the remnants of the whaling industry. For seven days we will observe penguins, seals and elephant seals in their natural environment. Glaciers and icebergs will surround us as we sail, as well as derelict whaling stations and memories of some of the first Antarctic Expeditions. The next leg will take us to the Falklands where for three days we will attempt to grasp at least some of the history of these islands. The expedition will finish at the "end of the world", in Ushuaia – the capital of Tierra del Fuego. It is the most southerly situated town on Earth and the springboard to the Antarctic. 3rd November Puerto Madryn : embarkation and preparation for the expedition. 3rd – 14th November : Puerto Madryn - South Georgia Distance: 1300nm , 11 days 15th – 21st November : exploring South Georgia 7 days 22th – 30th November : South Georgia - Falklands Distance: 800nm , 9 days 1st – 7th December : Falklands - Ushuaia Distance: 350nm , 4 days 8th December : disembarkation South Georgia When looking at a satelite picture of South Georgia one visualises it as a large congregation of clouds.

  • Anatomical Adaptations of Aquatic Mammals
    THE ANATOMICAL RECORD 290:507–513 (2007) Anatomical Adaptations of Aquatic Mammals JOY S. REIDENBERG* Center for Anatomy and Functional Morphology, Department of Medical Education, Mount Sinai School of Medicine, New York, New York ABSTRACT This special issue of the Anatomical Record explores many of the an- atomical adaptations exhibited by aquatic mammals that enable life in the water. Anatomical observations on a range of fossil and living marine and freshwater mammals are presented, including sirenians (manatees and dugongs), cetaceans (both baleen whales and toothed whales, includ- ing dolphins and porpoises), pinnipeds (seals, sea lions, and walruses), the sea otter, and the pygmy hippopotamus. A range of anatomical sys- tems are covered in this issue, including the external form (integument, tail shape), nervous system (eye, ear, brain), musculoskeletal systems (cranium, mandible, hyoid, vertebral column, flipper/forelimb), digestive tract (teeth/tusks/baleen, tongue, stomach), and respiratory tract (larynx). Emphasis is placed on exploring anatomical function in the context of aquatic life. The following topics are addressed: evolution, sound produc- tion, sound reception, feeding, locomotion, buoyancy control, thermoregu- lation, cognition, and behavior. A variety of approaches and techniques are used to examine and characterize these adaptations, ranging from dissection, to histology, to electron microscopy, to two-dimensional (2D) and 3D computerized tomography, to experimental field tests of function. The articles in this issue are a blend of literature review and new, hy- pothesis-driven anatomical research, which highlight the special nature of anatomical form and function in aquatic mammals that enables their exquisite adaptation for life in such a challenging environment.

USA Terrestrial Mammals Email: The voice box, or larynx, is the organ of vocalization used by most terrestrial mam- [email protected] mals. It initially evolved from the protective anatomy used to keep water out of a buoyancy organ in fish (the swim bladder). The main function of the larynx remains protection, only now it prevents incursions of foreign material into the “windpipe” (trachea) and lungs of mammals. The entrance of the larynx is sealed by a pair of vocal “cords” (vocal folds). In ad- dition, there are tall cartilages (epiglottic and corniculate) that act as splashguards to deflect food and water away from the opening. These cartilages overlap in front with the soft palate and behind with the posterior wall of the airspace (pharyn- geal wall) to interlock the larynx with the rear of the nasal cavity (Figure 1).

  • Adaptations of the Cetacean Hyolingual Apparatus for Aquatic Feeding and Thermoregulation
    THE ANATOMICAL RECORD 290:546–568 (2007) Adaptations of the Cetacean Hyolingual Apparatus for Aquatic Feeding and Thermoregulation ALEXANDER J. WERTH* Department of Biology, Hampden-Sydney College, Hampden-Sydney, Virginia ABSTRACT Foraging methods vary considerably among semiaquatic and fully aquatic mammals. Semiaquatic animals often find food in water yet con- sume it on land, but as truly obligate aquatic mammals, cetaceans (whales, dolphins, and porpoises) must acquire and ingest food under- water. It is hypothesized that differences in foraging methods are reflected in cetacean hyolingual apparatus anatomy. This study compares the musculoskeletal anatomy of the hyolingual apparatus in 91 cetacean specimens, including 8 mysticetes (baleen whales) in two species and 91 odontocetes (toothed whales) in 11 species. Results reveal specific adapta- tions for aquatic life. Intrinsic fibers are sparser and extrinsic muscula- ture comprises a significantly greater proportion of the cetacean tongue relative to terrestrial mammals and other aquatic mammals such as pin- nipeds and sirenians. Relative sizes and connections of cetacean tongue muscles to the hyoid apparatus relate to differences in feeding methods used by cetaceans, specifically filtering, suction, and raptorial prehension. In odontocetes and eschrichtiids (gray whales), increased tongue muscula- ture and enlarged hyoids allow grasping and/or lingual depression to gen- erate intraoral suction for prey ingestion. In balaenopterids (rorqual whales), loose and flaccid tongues enable great distention of the oral cav- ity for prey engulfing. In balaenids (right and bowhead whales), large but stiffer tongues direct intraoral water flow for continuous filtration feed- ing. Balaenid and eschrichtiid (and possibly balaenopterid) mysticete tongues possess vascular retial adaptations for thermoregulation and large amounts of submucosal adipose tissue for nutritional storage.
