The report was written by José Arévalo Baca, the 19th century Spanish ornithologist most recognized on a European scale and Head Professor at the University of Valencia since 1877. During the review process, the Natural Sciences Section of the Academy, referee of the Memory, indicated that the author had used the unpublished works of two professors from Malaga and Valencia, both deceased, without citing their names: Higinio Aragoncillo del Villar y Rafael Cisternas Fontseré. These criticisms were refuted by Arévalo with arguments and unpublished data that show here. However, in spite of his defense, Arévalo’s ornithological memory published in (1887) was, in several occasions willfully ignored. Likewise, we analyze stance of members of the 19th century scientific collective towards Arévalo’s monograph and Arévalo himself. We finish our study with a current, assessment of the Arévalo’s work.

This work studies the demographic implications of this food crisis in a rural population of the peninsular interior. The objectives are: to analyze the rates and characteristics of the birth rate, nuptiality and mortality of the population of Siles; to observe the socio-economic and biological factors that may have affected them; and to contrast the results with those reported by other populations. We have photographed and computerized the certificates of baptisms, marriages and deaths in the parish archives. We have also digitized the Chapter Acts and the budgets of the Town Council of the time, kept in the municipal archives. The results show that the last subsistence crisis of the old economic regime had important demographic repercussions on the population of Siles, with a high negative natural increase of -22.1 (caused by an increase of 65.7% in general mortality and a drop in birth rate of 8.9%) and a significant decrease in the general marriage rate of 45.7%. The work helps to alleviate the existing scarcity of studies that investigate in rural areas the demographic repercussions of the food crisis of 1868, a fundamental year in the contemporary history of Spain. It is an example to know what happened in deep Spain and to be useful for other comparative studies. La coyuntural crisis socioeconómica y de subsistencia de 1867-1868 generó, por un lado, el clima de agitación social en el que se gestó “La Gloriosa”, y, por otro, causó una grave crisis demográfica en muchas poblaciones de España. El trabajo estudia las implicaciones demográficas que tuvo esta crisis alimenticia en una población rural del interior peninsular. Los objetivos son analizar los índices y las características de la natalidad, nupcialidad y mortalidad de la población de Siles; observar los factores socio-económicos y biológicos que han podido afectarlos; y contrastar los resultados con los reportados por otras poblaciones. Se han fotografiado e informatizado las partidas de bautismos, matrimonios y óbitos del archivo parroquial. También se han digitalizado las Actas Capitulares y los presupuestos del Ayuntamiento de la época, conservadas en el archivo municipal. Los resultados muestran que la última crisis de subsistencia del antiguo régimen económico tuvo importantes repercusiones demográficas en la población de Siles, al registrarse un elevado crecimiento natural negativo de un -22,1 (originado por el aumento de un 65,7% de la mortalidad general y una bajada de la natalidad de un 8,9%) y un relevante descenso de la nupcialidad general de un 45,7%.

The objective is to present and compare the results of the variables studied: frequencies and rates, age at childbearing, secondary proportion by sex and seasonality. In addition, a section is dedicated to assisted reproduction techniques, as this is the factor that has most affected them. The data used come from the websites of the National Institute of Statistics, the Institute of Statistics and Cartography of Andalusia and the Spanish Fertility Society. The Weinberg method is used to differentiate between dizygotic and monozygotic births, and Henry’s seasonal coefficient is used to find their distribution by month. The frequencies report a maximum in Spain in 2014, and in 2017 in Andalusia. In both populations, twin births decrease in women younger than 34 years and increase in women older than 35 years. They report a sex ratio with great equality between sexes, and a seasonality with maximum coefficients in autumn and minimum in spring. Los partos gemelares constituyen un aspecto de la natalidad de gran interés porque sus frecuencias caracterizan a las poblaciones. El objetivo es realizar una exposición y comparación de los resultados de las variables trabajadas: frecuencias y tasas, edad de maternidad, proporción secundaria por sexos y estacionalidad, además, se dedica un apartado a las técnicas de reproducción asistida al ser el factor que más las ha afectado. Los datos utilizados proceden de las webs del Instituto Nacional de Estadística, el Instituto de Estadística y Cartografía de Andalucía y de la Sociedad Española de Fertilidad. Se emplea el método de Weinberg para diferenciar los partos dicigóticos monocigóticos, y el coeficiente estacional de Henry para hallar su distribución por meses. Las frecuencias reportan un máximo en España en el año 2014, y en el 2017 en Andalucía. En ambas poblaciones descienden los partos gemelares en las mujeres menores de 34 años y aumentan en las mayores de 35.

Myrrh tree’ scientific name is comyphora mirra and mastic tree’ scientific name is Pistacia lentiscus. Both, mastic and myrrh have been profusely used alone or with other ingredients. Ancient Mediterranean cultures like Egyptian, Ancient Greece, Roman Empire or Mesopotamia have been dealing with those products, in that way Phoenicians were the most famous in the commerce through the Mediterranean’ sea. Furthermore, Egyptian were famous for their mummification rites, to preserve dead bodies’ decomposition, myrrh is one of the most important ingredients used in the mummification process. In the other hand, mastic and myrrh have been known as being part of different medical treatment. In this respect the Mesopotamian Clay Tablet (2000 years B.C.), mention the use of those compounds in medicine and The Ebers Papyrus (XVI B.C. century) describe the Kyphi utility of mastic and myrrh as a chewing gum or as a gargling, in order to clean, disinfect and give off an odor in the mouth. Different literature´s authors have related the use of mastic and myrrh in different ways. The first one as an aromatic spice in order to control body or mouth stink. Hipócrates (V B.C. century) in his humor theory (Corpus Hipocraticum) recommended gargling and chewing made with mastic, myrrh and other ingredients to throw out mouth’ stink. The second one is cited on The Bible by his use in traditional religious rites like the Jewish body preservation rites, the Catholic sacrament of the lasts rites given before dying, or the narcotic effect of wine mixed with myrrh that offered to Jesus during the Crucifixion. Along these lines, Dioscórides (II Century) wrote that by adding to the wine a small amount of myrrh could be a remedy for dry coughs and indigestion. We focused this paper in their utility to provide health in mouth and teeth’ diseases. Therefore, since ancient times, authors like Gaius Plinius Secundus recommended a poultice made with myrrh mixed with ash to clean teeth. Abulcasis (s.X) and Avenzoar (s.XI) (Ancient Islamic Culture) wrote about different tools and treatment to preserve teeth from illness as mijrad, with different ingredients, one of them was mastic, to polish teeth. Four hundred years after, Laguna (1555) worked in translation of Dioscórides’ book (s.I) and wrote some additional comments in which he wrote about the use of mastic to control fetid breath. In the Spanish literature, there are some authors that make reference to the use of mastic and myrrh. Two of them are Celestina, the protagonist in La Tragicomedia de Calisto y Melibea, first published in 1499 (Rojas 1990) and Aldonza Lorenzo the protagonist in La Lozana Andaluza, first published in 1528 (Delicado, 2004). Both of them are sorceress-mender that made potions with mastic and myrrh used in different treatments related with mouth and tooth illness. They recommend oils and different kind of waters like rainwater or bitter mastic water to rinse the","PeriodicalId":286201,"journal":{"name":"Boletín de la Real Sociedad Española de Historia Natural","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123017755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monthly physico-chemical variables of the Casa de Campo Lake, an artificial basin in Western Madrid city, are reported here for an annual cycle following its reflooding in 2019 and comparing them with those of other similar environments. Nutrient features of the main watercourse draining to the Lake have also been studied. The Lake is a polymictic, low-salinity and eutrophic site and its nutrient dynamics shows a seasonal pattern for nitrogen, but subtle seasonality for organic carbon and phosphorus. Phytoplankton chlorophyll-a, however, does not follow the same patterns because algal recolonization has taken place slowly in the first months, not enabling the summer peak to occur. The Lake is mostly phosphorus-limited. Organic phosphorus, nitrogen and phosphorus concentrations are roughly similar to those of other urban lakes. Nutrient enrichment aside, arising from both the unlocalized setting of wastewater point sources and the catchment and surrounding runoff, the Lake does not experience pollution by heavy metals and organics. The Lake environmental quality could be improved if those point sources were identified and abated. Dado el imparable crecimiento de la población en las ciudades de todo el mundo, se está prestando cada vez más atención a los lagos de entornos urbanos y periurbanos. En este artículo se describe mensualmente la físico-química del Lago de la Casa de Campo durante un ciclo anual tras su inundación en 2019, comparándola con datos antiguos y con otros lagos de la misma índole existentes en otras zonas del Globo. Paralelamente, se han analizado también las aguas del arroyo Meaques, la principal vía de aporte hídrico al Lago. Este es polimíctico, de baja salinidad, eutrófico y su dinámica nutritiva muestra pautas claramente estacionales para el nitrógeno y menos patentes para el carbono orgánico o el fósforo. La clorofila fitoplanctónica, sin embargo, no siguió dichas pautas porque la recolonización de las algas ocurrió lentamente durante los primeros meses, sin dar tiempo a que tuviera lugar el máximo estival de ese año. La limitación del crecimiento vegetal en este ecosistema se debe fundamentalmente al fósforo. Las concentraciones de carbono orgánico, nitrógeno y fósforo son similares a las de otros lagos urbanos del mundo. Aparte del enriquecimiento nutritivo, derivado fundamentalmente de la escorrentía en su cuenca hidrográfica y en el entorno de su cubeta y de aportes de aguas residuales no ubicados, el Lago carece de contaminación por metales pesados o productos de síntesis orgánica. Para mejorar la calidad ambiental del mismo sería conveniente identificar y eliminar las fuentes puntuales de contaminación.","PeriodicalId":286201,"journal":{"name":"Boletín de la Real Sociedad Española de Historia Natural","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123865480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We delve into national background that led to the confluence of various fishing, oceanographic and meteorological initiatives. Along the century of CIESM life, the IEO was always the Spanish representative. Both, the foundation and the 50th anniversary Congress took place in Madrid in 1919 and 1969 respectively. Also, several Congresses were carried out in Spain, such as in Madrid (1924), Malaga (1929), Palma de Mallorca (1986) and Barcelona (2004). The first created CIESM committees were on oceanography (physics and chemistry), meteorology and general and applied biology (fisheries), and were attended by IEO experts: Odón de Buen and his sons Fernando and Rafael, Jaime Ferrer, Antonio Ipiens and José Giral. Overall, 196 authors including 81 women (41.3 %) attended the 26 Congresses and 274 scientific communications were presented in the period 1960-2019, most of them to different committees in the last ten Congresses (1992-2019) Describimos y cuantificamos las principales aportaciones del Instituto Español de Oceanografía (IEO) en el primer siglo de historia de esa fructífera Comisión, con su sede en Mónaco, durante el cual el número de estados miembros ha ido aumentado desde 7 hasta los actuales 24.
