His most important contributions nclude, concepts, theories and classifications currently used such as, for example, the ecological niche concept, Hutchinson’s paradox and lake classifications. Hutchinson redefined the ecological niche concept based on previous ideas of Grinnell and Elton, suggesting that it should be considered as a hypervolume in the environmental space caused by the ultidimensional response of variables that determine the stability of populations. This new perception of the ecological niche has been fundamental for the development of other investigations in different fields of biology, in particular in ecology, evolution, and biogeography. Furthermore, Hutchinson’s treatise on limnology is considered as the most extensive compilation of limnology. Hutchinson aimed to answer why several species of phytoplankton that compete for the same resources can coexist in an aquatic ecosystem which is usually nutrient deficient (known as the Hutchinson’s paradox). The scientific advances promoted by Hutchinson have inspired many generations of biologists. George Evelyn Hutchinson es reconocido como uno de los mejores limnólogos y ecólogos del siglo XX, cuyas aportaciones han sido cruciales para el desarrollo de la ecología y limnología moderna. Sus más importantes contribuciones incluyen conceptos, teorías y clasificaciones vigentes en la actualidad como, por ejemplo, el concepto de nicho ecológico, la paradoja de Hutchinson y las clasificaciones de lagos. A partir de las ideas de Grinnell y Elton, Hutchinson sugirió que el concepto de nicho ecológico debía considerarse como un hipervolumen en el espacio ambiental originado por la respuesta multidimensional de las variables que determinan la estabilidad de las poblaciones. Esta nueva percepción del nicho ecológico ha sido fundamental para el desarrollo de otras investigaciones en diferentes campos de la biología, particularmente en la ecología, la evolución y la biogeografía. Por otro lado, el tratado de limnología realizado por Hutchinson es considerado como la recopilación más extensa de la limnología. Hutchinson intentó dar respuesta a por qué varias especies del fitoplancton que compiten por los mismos recursos pueden coexistir en un ecosistema acuático que por naturaleza suele ser deficiente en nutrientes (conocido como la paradoja de Hutchinson). Los avances científicos promovidos por Hutchinson han servido de fuente de inspiración a muchas generaciones de biólogos.","PeriodicalId":286201,"journal":{"name":"Boletín de la Real Sociedad Española de Historia Natural","volume":"161 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":"134144060","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}

It is one of the oldest sources of textile fibres, but it has also stood out for its medicinal and food uses. The domestication process carried out by humans, focused on obtaining different products, has brought with it a biological evolution from the anatomical, morphological, physiological and chemical points of view. Furthermore, hybridization has also largely conditioned the evolutionary process of hemp. This has made the taxonomic classification of hemp extremely difficult, which has been highly controversial. During the Early Modern Period, some authors considered that there were different species, while others affirmed that all the specimens corresponded to a single species. The chemical characterization of cannabinoids, the most characteristic compounds of the secondary metabolism of hemp, took place in the 20th century. Because of this, the content of some of these compounds was included as a classification criterion. However, the discrepancies between the authors on whether the Cannabis genus was monotypic or polytypic were not resolved. In the 21st century, the taxonomic classification of hemp continues under study because of the absence of consensus. El cáñamo (Cannabis sativa L.) es una planta ampliamente extendida por el mundo. Se trata de una de las fuentes más antiguas de fibras textiles, pero también ha destacado por sus usos medicinales y alimentarios. El proceso de domesticación llevado a cabo por el ser humano, centrado en la obtención de productos diferentes, ha llevado consigo una evolución biológica de planta desde los puntos de vista anatómico, morfológico, fisiológico y químico. Además, la hibridación también ha condicionado en gran medida el proceso de evolución del cáñamo, lo que ha dificultado enormemente su clasificación taxonómica, que ha sido muy controvertida. Durante la Edad Moderna, algunos autores consideraban que había diferentes especies, mientras que otros afirmaban que todos los especímenes se correspondían con una única especie. En el siglo XX tuvo lugar la caracterización química de los cannabinoides, los compuestos más característicos del metabolismo secundario del cáñamo, y esto permitió incluir como criterio de clasificación el contenido de algunos de ellos.

The trip was carried out on board a ship of the Norwegian company Hurtigruten named Roald Amundsen, which set sail from the port of Reykjavik and, after crossing the Strait of Denmark, arrived at Umivik Bay, on the south-eastern coast of Greenland. Over the next twelve days, the ship toured the southern fjords and bays of this immense island of Danish sovereignty, such as the Skjoldungen or the Prins Christian Sound, or human settlements such as Aappilattoq, Qaqortoq, Qassiarsuk, Igaliku, Ivittuut, Nuuk, the capital and main city of the territory, Kapisillit and Maniitsoq, to finish sailing through one of the longest Greenlandic fjords, the Kangerlussuaq Fjord or Søndre Strømfjord, at the bottom of which is located the international airport of Kangerlussuaq, where the authors took the plane back to Denmark. From an environmental point of view, Greenland is a vulnerable territory, climate change is seen on this border more clearly than in other places on the planet: retreating glaciers, changes in the relief, increasing temperatures, etc. Likewise, the authors present the sensations that, as naturalists, landscapes, flora, fauna and other such unique experiences caused them.

A lo largo de los siguientes doce días, el barco recorrió los fiordos y bahías del sur de esta inmensa isla de soberanía danesa, como el Skjoldungen o el Prins Christian Sound , o asentamientos humanos como Aappilattoq, Qaqortoq, Qassiarsuk, Igaliku, Ivittuut, la capital del territorio Nuuk, Kapisillit y Maniitsoq, para terminar navegando por uno de los más largos fiordos groenlandeses, el Kangerlussuaq Fjord o Søndre Strømfjord, al fondo del cual está el aeropuerto internacional de Kangerlussuaq, donde los autores tomaron el avión de regreso a Dinamarca. Desde el punto de vista ambiental, Groenlandia es un territorio vulnerable, el cambio climático se aprecia en esta frontera con más nitidez que en otros lugares del planeta: glaciares en retroceso, cambios en el relieve, aumento de la temperatura, etc. Asimismo, los autores exponen las sensaciones que, como naturalistas, les causaron los paisajes, la flora, la fauna y otras experiencias tan singulares.","PeriodicalId":286201,"journal":{"name":"Boletín de la Real Sociedad Española de Historia Natural","volume":"39 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":"121761414","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}
