The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges. -
House Sparrow Eradication Attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile

House sparrow eradication attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile House sparrow eradication attempt on Robinson Crusoe Island, Juan Fernández Archipelago, Chile E. Hagen1, J. Bonham1 and K. Campbell1,2 1Island Conservation, Las Urbinas 53 Santiago, Chile. <[email protected]>.2School of Geography, Planning & Environmental Management, The University of Queensland, St Lucia 4072, Australia. Abstract House sparrows (Passer domesticus) compete with native bird species, consume crops, and are vectors for diseases in areas where they have been introduced. Sparrow eradication attempts aimed at eliminating these negative eff ects highlight the importance of deploying multiple alternative methods to remove individuals while maintaining the remaining population naïve to techniques. House sparrow eradication was attempted from Robinson Crusoe Island, Chile, in the austral winter of 2012 using an experimental approach sequencing passive multi-catch traps, passive single- catch traps, and then active multi-catch methods, and fi nally active single-catch methods. In parallel, multiple detection methods were employed and local stakeholders were engaged. The majority of removals were via passive trapping, and individuals were successfully targeted with active methods (mist nets and shooting). Automated acoustic recording, point counts and camera traps declined in power to detect individual sparrows as the population size decreased; however, we continued to detect sparrows at all population densities using visual observations, underscoring the importance of local residents’ participation in monitoring. Four surviving sparrows were known to persist at the conclusion of eff orts in 2012. Given the lack of formal biosecurity measures within the Juan Fernández archipelago, reinvasion is possible. -

Variation in the Ivlitociiondrial Control Region in the Juan Fernández Fur Seal {Arctocephalus Philippii)
Variation in the IVlitocIiondrial Control Region in the Juan Fernández Fur Seal {Arctocephalus philippii) s. Goldsworthy, J. Francis, D. Boness, and R. Fleischer The Juan Fernández fur seal (Arctocephalus philippli) was allegedly extremely abundant, numbering as many as 4 million prior to sealing which continued from the late 17th to the late 19th century. By the end of the sealing era the species was thought to be extinct until they were rediscovered at Alejandro Selkirk Island In 1965. Historic records would suggest that the species underwent a substantial pop- ulation bottleneck as a result of commercial sealing, and from population genetic theory we predicted that the genetic variability In the species would be low. We compared the mtDNA control region sequence from 28 Juan Fernández fur seals from two Islands In the Juan Fernández Archipelago (Chile). Contrary to expecta- tion, we found that variation In the Juan Fernández fur seals Is not greatly reduced In comparison to other pinniped taxa, especially given the apparent severity of the bottleneck they underwent. We also determined minor, but significantly different haplotype frequencies among the populations on the two Islands (Alejandro Selkirk and Robinson Crusoe Islands), but no difference In their levels of variability. Such differences may have arisen stochastically via a recent founder event from Alejan- dro Selkirk to Robinson Crusoe Island or subsequent genetic drift. Population genetic tiieory malíes clear (Bester 1987; Boyd 1993; Guinet et al. quantitative predictions of the reductions 1994; Hofmeyr et al. 1997; Shaughnessy in genetic variability expected from pop- and Goldsworthy 1990).

Inside Out Castaway WORKSHEET A 1. Quickly read through the story narrated by Alexander Selkirk. Then answer the questions on Worksheet B. I was born in Largo, Scotland, in 1676. My father was a tanner – he made clothes and other items from leather – and a cobbler (a shoemaker). Many people said that I was a “difficult person. Maybe they were right, I never had much patience with fools. In 1695 I became a sailor. I was a good seaman and worked my way up to the position of sailing master quickly. In 1705, I was appointed Master of the ship Cinque Ports, one of two vessels under the overall command of William Dampier. We were privateers, pirates who had the blessing of our government to attack Spanish ships off the South American coast and steal gold, silk and jewels. We weren’t paid a wage - whatever we stole, we kept. Although Dampier was a good navigator and mapmaker, he clearly had no idea how to run a privateering expedition. By the time we had crossed the Atlantic and reached Brazil, many men were hungry and sick. Worse still, we already had cases of scurvy (the fatal illness caused by lack of vitamins) aboard. Despite the condition of the men, we were ordered to make our way around Cape Horn, a most treacherous stretch of water, south of Chile. We finally made it, although the ship was badly damaged. When we put in at Mas a Tierra, an island in the Juan Fernandez chain, four hundred miles off the coast of Chile, I had a big argument with the captain of my ship, Thomas Stradling. -
The Biology of Marine Mammals
Romero, A. 2009. The Biology of Marine Mammals. The Biology of Marine Mammals Aldemaro Romero, Ph.D. Arkansas State University Jonesboro, AR 2009 2 INTRODUCTION Dear students, 3 Chapter 1 Introduction to Marine Mammals 1.1. Overture Humans have always been fascinated with marine mammals. These creatures have been the basis of mythical tales since Antiquity. For centuries naturalists classified them as fish. Today they are symbols of the environmental movement as well as the source of heated controversies: whether we are dealing with the clubbing pub seals in the Arctic or whaling by industrialized nations, marine mammals continue to be a hot issue in science, politics, economics, and ethics. But if we want to better understand these issues, we need to learn more about marine mammal biology. The problem is that, despite increased research efforts, only in the last two decades we have made significant progress in learning about these creatures. And yet, that knowledge is largely limited to a handful of species because they are either relatively easy to observe in nature or because they can be studied in captivity. Still, because of television documentaries, ‘coffee-table’ books, displays in many aquaria around the world, and a growing whale and dolphin watching industry, people believe that they have a certain familiarity with many species of marine mammals (for more on the relationship between humans and marine mammals such as whales, see Ellis 1991, Forestell 2002). As late as 2002, a new species of beaked whale was being reported (Delbout et al. 2002), in 2003 a new species of baleen whale was described (Wada et al. -
The Fortress of American Solitude: Robinson Crusoe and Antebellum Culture, by Shawn Thomson
The Fortress of American Solitude: Robinson Crusoe and Antebellum Culture, by Shawn Thomson. Madison and Teaneck: Fairleigh Dickinson University Press, 2009. Pp. 243. $51.50. ISBN: 978-0- 838-6-4217-7. Positioned as a central component of a boy’s library in leather-bound and elaborately illustrated editions, Robinson Crusoe held conflicting cultural meanings in antebellum America (1815–1861). Its text encouraged young men to escape from the domestic realm and sentimental family, whilst the gilded pages of its book symbolized the comfort and prosperity of the white, middle-class home. Shawn Thomson’s Fortress of American Solitude: Robinson Crusoe and Antebellum Culture examines Defoe’s narrative as a vehicle employed by men and women in nineteenth-century America to express the conflicting pressures of individual achievement and familial relations that structured their lives. According to Thomson, Robinson Crusoe held a powerful yet precarious role as an “icon of manhood” in antebellum American culture (13), through whom discourses of gender, race, and social class could be mediated. Thomson’s study considers how literary and popular fiction, and non-fiction, produced in this cultural context focused on Crusoe as both helpless castaway and self-made man to reinforce and critique dominant middle-class ideologies. Thomson begins his argument by noting that he is neither attempting to trace Defoe’s influence on American letters by examining explicit references to Robinson Crusoe in antebellum works, nor is he seeking to catalogue American “Robinsonades”; such parameters explain the otherwise surprising exclusion of Poe’s The Narrative of Arthur Gordon Pym (1838) as a major case study.
