Nature provides a good opportunity to understand the dynamics of evolution. The country has a huge coastline, which experiences socio-cultural and natural vulnerability. The aim of the paper has been to describe the pattern of selection intensity among the east and west coastal populations of India. Differential fertility and mortality were collected from 2,099 females (mothers) of the western coasts of India, and secondary data were collected from the eastern coast of India for comparison purposes. Selection potential was computed using Crow’s index and Johnston & Kensinger’s index. The data involved a total of 7,512 pregnancies during their reproductive lifespan and the successful outcomes (live births) were 7,073. The total index (It) for eastern coast varied from 0.221 to 1.078. For the west coast, it varied from 0.262 to 0.617. Among the eastern coastal population groups, the mortality component of selection is comparatively higher than its fertility component, while it is just the reverse among the western coastal population groups.

At some undefined time in the fairly recent past central and western Madagascar witnessed a conceptual 'revolution' which had far-reaching political consequences. The religious beliefs and symbols which constituted the main ingredients of this 'revolution'--and probably also the people who propagated them--were in some way connected with the Zafindraminia-Antanosy and the Anteimoro of the southeastern and eastern coast. It is quite clear that these and similar groups had been strongly influenced by Islam and that they practiced what could perhaps be described as a corrupt or diluted Islam or a syncretic 'pagan' Muslim religion. (It is significant that as their name indicates the Zafindraminia claim descent from Raminia who they hold to have been the mother of Muhammad.) One of the main ingredients of this religion was the cult of the ody or guardian amulets, objects usually made of wood which are strikingly reminiscent of the so-called “charms” or “gris-gris” sold by Muslim clerics over much of Africa. Another ingredient is represented by the institution of ombiasy. The ombiasy (the main manufacturers of ody) whom the Frenchman Etienne de Flacourt at Fort-Dauphin in the seventeenth century took to be Muslim clerics were originally the “priests” (or the “devins guérisseurs,” according to Hubert Deschamps) of the Anteimoro and the Zafindraminia-Antanosy. Subsequently this institution was disseminated throughout nearly the whole of Madagascar. Yet another ingredient was the system of divination known as sikidy, which also spread to other parts of Madagascar, including Imerina and the Sakalava country.These beliefs, symbols, and institutions deeply influenced the people of the west coast (the present-day Sakalava country) and of central Madagascar (Imerina and Betsileo country).

The Arabs and Africans who first visited the west coast of India, came “Mu-abbar”: “from beyond” the sea. In the voyages of Ibn Batuta, translated by Dr. Lee, the country is called Muabbar, without any surmise that this is Malabar. The Syrian Christians who live in Travancore wrote the word in Syriac characters , and it has occurred to me that in careless writing this may have been altered into Malabar: a name unknown to the inhabitants; who fancy it is the European name for their country and language. The Eastern shore of India also was visited by men “from over the sea:” and the name Malabar has also been wrongly applied to the Eastern coast.

<p><strong>Abstract.</strong> Modern nautical charts, the result of scientific coastal research and survey, had been made from late 18th century, and at the end of 19th century almost of the world had been charted. Different to the neighbouring countries such as China and Japan, Korean peninsula had not been accurately charted until the end of 19th century. Moreover, during the 19th century, the shape of Korean peninsula had been changed several times in the Western nautical charts. However, in the academic circle of the history of cartography, this case was scantly examined. In this presentation, this author, firstly, analyse the changes in the shape of the Korean Peninsula on the British Charts in the 19th Century and, secondly, identifies factors that influence the changes. For this research, British nautical charts, which are the representative and finest charts during the 19th century in the world, are selected. Examined charts are ‘Map of the Islands of Japan Kurile &amp; C.’ (Year of 1811, 1818) of Aaron Arrowsmith (1750&amp;ndash;1823), the hydrographer to his majesty, ‘The Peninsula of Korea (No.1258)’ (year of 1840, 1849) and ‘(Preliminary Chart of) Japan, Nipon Kiusiu and Sikok and a part of the coast of Korea (No. 2347)’ (Year of 1855, 1862, 1873, 1876, 1892, 1898, 1902, 1914) of the British hydrographic office. According to the analysis, major shape changes of the Korean Peninsula were occurred in 1818, 1840, 1849, 1855, 1862, 1873, 1876, 1892, and the shape of the Peninsula became perfect in the chart of the year 1914.</p><p>Meanwhile, the factors of the shape changes of the Korean peninsula in these nautical charts were various voyages, expeditions, and military surveys to Korea. For example, the change in the map of 1818 was initiated by the voyage of the captain Basil Hall in 1816 to the west coast of Korea, and the change in the map of 1840 was made by the map of Korea of A.J. von Krusenstern (1770&amp;ndash;1846) and the voyage of H.H.Lindsay (1802&amp;ndash;1881) to the west coast of Korea in 1832. Moreover, the modification of 1849 was made by the outcome of E. Belcher’s scientific survey around Jeju Island and other southern islands of Korea. In 1852, French admiral G. de Roquemaurel (1804&amp;ndash;1878) surveyed eastern coast of Korea and drew nautical chart and this chart became the source of the British chart of the year 1855. A Russian admiral, Yevfimy Putyatin (1803&amp;ndash;1883), also surveyed east side of the peninsula and triggered the change of nautical chart of eastern part of Korea. During French campaign against Korea in 1866 and United States expedition to Korea in 1871, French and American navy surveyed west-middle part of the peninsula and added detailed coastline of it and British chart also reflected these changes. The Japan-Korea treaty of 1876 enabled coastal survey of the Korean peninsula by the Japanese navy by the article 7, which permitted any Japanese mariner to conduct surveys and mapping operations at will in the seas off the Korean Peninsula's coastline. By virtue of the treaty, Japan could directly surveyed coastline of Korea and could make updated nautical charts of Korea. These Japanese charts were circulated to the Western countries and British hydrographers made the best use of them. Thanks to this situation, the British admiralty could update the chart of Korean peninsula and the perfect one published in 1914.</p><p>This analysis contribute not only to understand how and why the shape of Korean peninsula changed in British nautical charts during the 19th century, but also to add the historical case of the map trade and geographical knowledge circulation in East Asia.</p>

The genus Corema D. Don (1826: 63) (Ericaceae Jussieu 1789: 159) comprises two species. Corema album (Linnaeus 1753: 1022) D. Don (1830: 460) (incl. C. febrifugum Boissier ex Willkomm & Lange 1877: 512) occurs on the west coast of the Iberian Peninsula (subsp. album) from Gibraltar to Finisterre (Willkomm & Lange 1877, Webb 1972, Cabezudo 1987, Villar 1993, Boratyński & Vera de la Puente 1994, López González 2001, Ruiz de la Torre 2006, Gil-López 2011), the Azores (subsp. azoricum Pinto da Silva 1966: 86), and the Mediterranean Basin (Spain, Alicante province, one population) (Solanas 1996, Solanas & Crespo 2001, Serra 2007, Aguilella et al. 2009). Corema conradii (Torrey 1837: 83) Torrey (1842: 1092) occurs on the eastern coast of North America from Newfoundland to New Jersey (Redfield 1884, McEwen 1894, Elisens 2009), and can be distinguished from C. album by its very small fruits which are devoid of fleshiness and covered with elaiosomes (oily appendages associated with ant dispersal) (Redfield 1884, McEwen 1894, Martine et al. 2005). Corema album subsp. azoricum exists on six of the nine islands of the Azores, and below 200 m (Franco 1984) this taxon has been recognized by some authors at the species level as C. azoricum [“azorica”] (Pinto da Silva 1966) Rivas Martínez, Lousã, Fernández Prieto, E. Días, J.C. Costa & C. Aguiar (in Rivas-Martínez, Fernández-González, Loidi, Lousã & Penas 2002: 700).

Ustilago spinificis, a floral smut of Spinifex hirsutus and S. sericeus, was collected across southern Australia from Yanchep, W.A. on the west coast to Seaspray, Vic, on the south-eastern coast and from the North Island of New Zealand. The host plants are most abundant on beaches with extensive sand dunes and the smut is common in regions where the host is abundant. The distribution limits for the smut are set by the replacement of S. hirsutus by a non-host, S. longifolius, north of Perth on the west coast; by the absence or rarity of host plants on rocky coastlines across the Great Australian Bight and in the SE. and SW. corners of Australia; and by the limited occurrence of host plants on the east coast of Australia. Spinifex inflorescences were sampled on 33 beaches and on the 29 beaches where smut was found the mean frequency of smutted inflorescences was 22%. These high infection rates represent a natural epidemic of a plant disease and data on other natural populations of smut fungi are presented to show that these results are not exceptional.

Cape anchovy Engraulis encrasicolus is an ecologically and economically important pelagic fish species occurring along the coast of South Africa. A recent eastward shift in Cape anchovy distribution indicates that environmental conditions are becoming more favorable for the species on the east coast. This shift is particularly important in the sheltered Algoa Bay region, a nursery area for fish larvae. However, the relatively low productivity of the Agulhas Current Large Marine Ecosystem on the eastern coast of South Africa may result in an anchovy population in poorer nutritional condition and with slower growth rates than the west coast population. Using otolith and nucleic acid analyses, the growth rates of anchovy larvae from the western and southeastern coasts of South Africa were compared. The otolith analysis results indicated that, at any given age, individual growth rates for anchovy larvae were higher on the southeast coast than on the west coast. The RNA:DNA values also indicated that instantaneous growth rates of anchovy larvae were higher in Algoa Bay than on the west coast. At the time of sampling, chlorophyll and zooplankton productivity were higher at sampling sites in Algoa Bay than sites on the west coast, potentially due to favorable oceanographic features in the bay. As such, the results suggest that Algoa Bay is a suitable and potentially favorable nursery area for the early stages of anchovy, highlighting the importance of separate management of the southeast coast region in a changing world.
