CIEN. BOL. IDEA, n.° 23 - 1978 ANALISIS DEL CRECIMIENTO EN LOS MUCHACHOS DE OVIEDO POR M. FERNANDEZ RICO En el presente trabajo se analiza el crecimiento en 692 mucha­ chos de Oviedo, todos ellos varones y cuyos cuatro abuelos son as­ turianos. Los parámetros analizados han sido: estatura, talla sentado, peso, perímetro cefálico, anchura biacromial, perímetro torácico en reposo respiratorio, anchura bicrestal y perímetro abdominal, sien­ do no solo analizados independientemente, sinó también compara­ dos con los publicados para otras poblaciones infantiles españolas. Las medidas numéricas de los distintos parámetros han sido recogidas durante el curso académico 1974-1975 en distintos cen­ tros docentes de Oviedo y agrupadas para su estudio en función de la edad, habiéndose hecho la distribución de edades en periodos de seis meses con una repartición de tres meses a cada lado de la edad considerada. LA ESTATURA Los valores medios para la estatura presentan un ritmo de cre­ cimiento ascendente aunque no uniforme. Podemos apreciar un período de crecimiento rápido que finaliza a los ocho años, un pe­ ríodo de crecimiento más lento entre ocho y medio y once y medio años, y un período acelerado a partir de los once años y medio (cuadro I, fig. 1). La amplitud de la variación no es elevada y está homogénea­ mente repartida a ambos lados de la media. Tampoco presenta este carácter valores elevados para la desviación típica y el coefi­ ciente de variabilidad, aunque ambos aumentan con la edad, sien­ do más acusado dicho aumento a partir de los once años y medio.

La comparación de los valores medios estaturales obtenidos por nosotros, con los publicados por FERRER (B.) y SARRIA (A.) en 1975 para niños de un grupo escolar de Zaragoza, y los publicados en 1968 por GARCIA ALMANSA para muchachos madrileños, nos muestra que las tres poblaciones presentan igual estatura a los once y medio años, y que mientras con anterioridad los valores medios de los muchachos de Oviedo y Zaragoza se entrecruzan va­ rias veces, permaneciendo los de Madrid con estatura más elevada, posteriormente los muchachos de Oviedo y Madrid se igualan, que­ dando los de Zaragoza más bajos (Fig. 1). Las diferencias entre los valores medios no son estadísticamen­ te significativas cuando comparamos con los muchachos de Ma­ drid, pero sí lo son con los muchachos de Zaragoza a los cinco, diez y medio, doce y medio y trece y medio años. La comparación con los valores medios estaturales obtenidos en 1946 por FERNANDEZ CABEZA al estudiar la población infan- Fig. 1 Valores medios para el aumento de estatura en las poblaciones infantiles de Oviedo,Zaragoza,Madrid y Mieres. til y juvenil de Mieres (Asturias), nos permite apreciar que la es­ tatura de los muchachos de Oviedo es considerablemente superior a la presentada por los muchachos de Mieres, aumentando la di­ ferencia con la edad desde los cinco (6,1 cm.) hasta los catorce años y medio (15,7 cm.), lo cual no impide que el curso que siguen ambas representaciones gráficas sea bastante similar (fig. 1). La evaluación de este aumento es difícil, debido a no poder se­ parar la parte que de él puede corresponder al posible aumento secular, de la que corresponde a la anticipación de la pubertad, sin tampoco olvidar que el período durante el cual FERNANDEZ CABEZA realizaron su trabajo, no solo coincide con una época de penuria económica sinó también con lo que IMBELLONI (1948) denomina fase catasomática. La comparación de ambas poblaciones horizontalmente nos muestra el adelanto en años que para alcanzar un mismo valor es- tatural presenta la población de Oviedo respecto de la de Mieres y que en general se puede considerar de dos años, encontrándose el máximo (dos años y medio) a los 139,2 cm. de altura. TALLA SENTADO Los valores medios presentan un enlentecimiento en la veloci­ dad de crecimiento entre los nueve y doce y medio años, comen­ zando a partir de los trece a hacerse acelerada (cuadro II, fig. 2). La amplitud de la variación no es elevada, y está homogénea­ mente repartida a ambos lados de la media. Los valores de la desviación típica y del coeficiente de variabi­ lidad son pequeños y aumentan poco con la edad, encontrándose el mínimo valor a los once años. Para el índice cormico, estos muchachos, presentan valores que los clasifican como macrocormes hasta los ocho años, metriocor- mes entre ocho y once años, braquicormes entre once y medio y quince años, volviéndose a los quince y medio de nuevo metrio- cormes. El mínimo valor (Ic.=50,00) lo presentan a los trece y me­ dio años. El índice de MANOUBRIER presenta en todo momento valores elevados. Al comparar con los muchachos de Zaragoza, apreciamos que siguen un curso de crecimiento mas regular que los muchachos de Oviedo, lo que no evita que los valores medios se entrecrucen, y que aunque inicialmente los muchachos de Zaragoza presentan ma­ yor busto, queden al final ambos grupos con valores similares, (fig.

  • Evolutionary History of a Vanishing Radiation
    Lee et al. BMC Evolutionary Biology 2014, 14:202 http://www.biomedcentral.com/1471-2148/14/202 RESEARCH ARTICLE Open Access Evolutionary history of a vanishing radiation: isolation-dependent persistence and diversification in Pacific Island partulid tree snails Taehwan Lee1, Jingchun Li1, Celia KC Churchill2 and Diarmaid Ó Foighil1* Abstract Background: Partulid tree snails are endemic to Pacific high islands and have experienced extraordinary rates of extinction in recent decades. Although they collectively range across a 10,000 km swath of Oceania, half of the family’s total species diversity is endemic to a single Eastern Pacific hot spot archipelago (the Society Islands) and all three partulid genera display highly distinctive distributions. Our goal was to investigate broad scale (range wide) and fine scale (within‐Society Islands) molecular phylogenetic relationships of the two widespread genera, Partula and Samoana. What can such data tell us regarding the genesis of such divergent generic distribution patterns, and nominal species diversity levels across Oceania? Results: Museum, captive (zoo) and contemporary field specimens enabled us to genotype 54 of the ~120 recognized species, including many extinct or extirpated taxa, from 14 archipelagoes. The genera Partula and Samoana are products of very distinct diversification processes. Originating at the western edge of the familial range, the derived genus Samoana is a relatively recent arrival in the far eastern archipelagoes (Society, Austral, Marquesas) where it exhibits a stepping‐stone phylogenetic pattern and has proven adept at both intra‐and inter‐ archipelago colonization. The pronounced east–west geographic disjunction exhibited by the genus Partula stems from a much older long-distance dispersal event and its high taxonomic diversity in the Society Islands is a product of a long history of within‐archipelago diversification.

Gillespie1,*, Elin M. Claridge2 and Sara L. Goodacre3 1Department of Environmental Science, University of California, 137 Mulford Hall, Berkeley, CA 94720-3114, USA 2UC Berkeley Gump Research Station, BP 244, Maharepa, Moorea 98728, French Polynesia 3Institute of Genetics, University of Nottingham, Nottingham NG7 2UH, UK The islands of French Polynesia cover an area the size of Europe, though total land area is smaller than Rhode Island. Each hot spot archipelago (Societies, Marquesas, Australs) is chronologically arranged. With the advent of molecular techniques, relatively precise estimations of timing and source of colonization have become feasible. We compile data for the region, first examining colonization (some lineages dispersed from the west, others from the east). Within archipelagos, blackflies (Simulium) provide the best example of adaptive radiation in the Societies, though a similar radiation occurs in weevils (Rhyncogonus). Both lineages indicate that Tahiti hosts the highest diversity. The more remote Marquesas show clear examples of adaptive radiation in birds, arthropods and snails. The Austral Islands, though generally depauperate, host astonishing diversity on the single island of Rapa, while lineages on other islands are generally widespread but with large genetic distances between islands. More recent human colonization has changed the face of Polynesian biogeography. Molecular markers highlight the rapidity of Polynesian human (plus commensal) migrations and the importance of admixture from other populations during the period of prehistoric human voyages.

Tropical oceanic islands support unique land snail faunas with high endemism; biodiversity of land snails in Pacific islands is estimated to be around 5 000 species, most of which are endemic to single islands or archipelagos. Many are already under threat from the rosy wolfsnail (Euglandina rosea), an introduced predatory snail. They now face a newer but no less formidable threat, the introduced flatworm Platydemus manokwari (Platyhelminthes). Both \"biocontrol\" species continue to be dispersed to new areas in attempts to control Achatina fulica. view this species on IUCN Red List Species Description This flatworm has a uniform exterior appearance. The adult length is 40 to 65mm long, 4 to 7mm wide. The head end is more pointed than tail end. The flattened cross section has a thickness less than 2mm. The colour of the dorsal surface is very dark brown, almost black, with a thin medial pale line. The ventral surface is pale gray. (de Beauchamp, 1963). Notes A rhynchodemid flatworm, Platydemus manokwari, was discovered in New Guinea and originally described in 1962 (Kaneda Kitagawa and Ichinohe 1990). Little has been known of its biology except that it is nocturnal, and there apparently is no report on the rearing of this flatworm (Kaneda Kitagawa and Ichinohe 1990).

  • Investigating Causes of Population Decline in Captive Partula Clara And
    Investigating causes of population decline in captive Partula clara and Partula tohiveana Polynesian snails Ana Gouveia, Roamin Pizzi, Paul Pearce-Kelly, Donald MacFarlane, Dave Clarke, Shaheed MacGregor, Belinda Clark and Wayne Boardman. Zoological Society of London Abstract Partula species Polynesian tree snails are small Molluscs belonging to the class Gastropoda, order Stylommatophora, family Partulidae. They are a unique genus endemic to the Pacific region and more specifically to the Society Islands. There are over one hundred species of Partula snails described with 79 species on the International Union for the Conservation of Nature (IUCN) Red List. Fifty species are currently classified as extinct, 14 as extinct in the wild and 15 as critically endangered. Wild populations have declined since the introduction of a predatory snail, Euglandina rosea, introduced to control the also introduced Giant African land snail (Achatina fulica) which had become an agricultural pest. The London Zoo co-ordinates a worldwide captive breeding programme for Partula snails and occasional high mortality rates have occurred in a variety of species. While the extinction of Partula turgida in captivity has been postulated to have been due to a Microsoridian infection investigations in to the majority of other captive Partula species population declines have failed to identify causative diseases. A study of the population dynamics of a habitat generalist and a habitat specialist Partula species and the daily minimum and maximum temperature and humidly over a three year period was performed. At the same time histopathology of dead snails was performed to help eliminate the possibility of infectious diseases playing a role in the population declines.

  • Euglandina Rosea Global Invasive
    FULL ACCOUNT FOR: Euglandina rosea Euglandina rosea System: Terrestrial Kingdom Phylum Class Order Family Animalia Mollusca Gastropoda Stylommatophora Spiraxidae Common name Rosige Wolfsschnecke (German), rosy wolf snail (English), cannibal snail (English) Synonym Similar species Summary The carnivorous rosy wolfsnail Euglandina rosea was introduced to Indian and Pacific Ocean Islands from the 1950s onwards as a biological control agent for the giant African snail (Achatina fulica). E. rosea is not host specific meaning that native molluscs species are at risk of expatriatioin or even extinction if this mollusc-eating snail is introduced. Partulid tree snails of the French Polynesian Islands were particularly affected; having evolved separately from each other in isolated valleys, many Partulid tree snails have been lost and today almost all the survivors exist only in zoos. view this species on IUCN Red List Species Description The shell is large (up to 76 mm in height, 27.5 mm in diameter), thick and has prominent growth lines (University of Florida 2009). The shape of the shell is fusiform with a narrow ovate-lunate aperture and a truncated columella; typically, the shell color is brownish-pink (University of Florida 2009). Adult Euglandina grow from about seven to 10 cm long (Clifford et al. 2003). Habitat Description Euglandina rosea is usually found singly in hardwood forests, roadsides and urban gardens in its native range in Florida (Hubricht 1985, University of Florida 2009). Reproduction Euglandina rosea is a cross-fertilising egg-laying hermaphrodite. Chiu and Chou (1962, in Univeristy of Florida 2009) gave details of the biology of Euglandina in Taiwan. Individuals live up to 24 months.

Brasil 2 Departamento de Invertebrados, Museu Nacional, Quinta da Boa Vista, São Cristovão, 20940-040, Rio de Janeiro, RJ, Brasil; [email protected]; [email protected] Abstract: Studies on terrestrial prosobranchs (streptoneureans) and shelled pulmonates (euthyneureans) show the significant diversity of the Brazilian malacofauna. These mollusks are still poorly known, despite the increas- ing interest in the group that started in the XVIII century when land mollusks began to be collected and deposit- ed in scientific collections. The species are arranged in alphabetical order; the taxonomic combination is updat- ed when possible with the original and other bibliographic references. This checklist includes original study of specimens deposited in Brazilian, American and European collections, as well as names and additional data of important early naturalists and current researchers of the group. Species are here associated to their original ref- erences; geographical distribution and other taxonomic references were added to each. A total of 590 species were found (27 families and 95 genera). The systematic arrangement of suprageneric and generic taxa was based on Taylor & Sohl (1962), Thiele (1929-1931), Wenz (1938-1944) and Zilch (1959-1960). Breure (1973-1985) was especially useful regarding Bulimuloidea because the characteristics of some subgenera justified a raise to generic level.
