Los socios de la RSEHN y el desarrollo de las colecciones científicas del MNCN

Valencia, del 8 al 11 de septiembre de 2021. El tema principal tuvo como lema: “La huella Humana en la Naturaleza”.Las colecciones científicas son una infraestructura de investigación única e irremplazable para numerosas áreas de la ciencia. En la actualidad, se estima que en el Museo Nacional de Ciencias Naturales se conservan 10 millones de especímenes, lo que suponen casi la mitad de todos los conservados en España. Esta infraestructura científica o este tesoro, como puede ser llamado, se ha reunido principalmente a lo largo del último siglo, y se debe al trabajo conjunto de muchos especialistas, estudiosos e interesados en diferentes disciplinas de las ciencias naturales. En esta ponencia se quiere poner en valor la aportación de los socios de la RSEHN en el incremento y desarrollo de las colecciones científicas del MNCN. Se ha realizado un análisis preliminar de los fondos de las diferentes colecciones del MNCN y de los ingresos efectuados por los socios de RSEHN desde su fundación (1871) hasta el momento en que abandona el MNCN (1971). Se realizó en cada una de ellas una consulta de los diferentes colectores y personas que aportaron especímenes y que aparecen en las bases de datos, cruzándola con la base de datos de socios durante dicho periodo. Se ha contabilizado el número de especímenes, número de tipos y taxones correspondientes a éstos. La cifra de socios total supera el centenar. El número de ejemplares ingresados por estos socios, entre esas fechas, se estima que superan el millón y medio, lo que supone al menos un 15% del total actual estimado. Hay que tener en cuenta que las colecciones no se encuentran informatizadas al 100%

Relationship between self-reported dietary intake and physical activity levels among adolescents: The HELENA study

Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing our energy balance and body composition. The objective of the present study is to describe the relationship between energy, nutrient and food intake and the physical activity level among a large group of European adolescents. Methods The study comprised a total of 2176 adolescents (46.2% male) from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. Dietary intake and physical activity were assessed using validated 24-h dietary recalls and self-reported questionnaires respectively. Analyses of covariance (ANCOVA) were used to compare the energy and nutrient intake and the food consumption between groups of adolescents with different physical activity levels (1st to 3rd tertile). Results In both sexes no differences were found in energy intake between the levels of physical activity. The most active males showed a higher intake of polysaccharides, protein, water and vitamin C and a lower intake of saccharides compared to less active males. Females with the highest physical activity level consumed more polysaccharides compared to their least active peers. Male and female adolescents with the highest physical activity levels, consumed more fruit and milk products and less cheese compared to the least active adolescents. The most active males showed higher intakes of vegetables and meat, fish, eggs, meat substitutes and vegetarian products compared to the least active ones. The least active males reported the highest consumption of grain products and potatoes. Within the female group, significantly lower intakes of bread and cereal products and spreads were found for those reporting to spend most time in moderate to vigorous physical activity. The consumption of foods from the remaining food groups, did not differ between the physical activity levels in both sexes. Conclusion It can be concluded that dietary habits diverge between adolescents with different self-reported physical activity levels. For some food groups a difference in intake could be found, which were reflected in differences in some nutrient intakes. It can also be concluded that physically active adolescents are not always inclined to eat healthier diets than their less active peers.The HELENA study took place with the financial support of the European Community Sixth RTD Framework Programme (Contract FOOD-CT: 2005-007034). This work was also partially supported by the European Union, in the framework of the Public Health Programme (ALPHA project, Ref: 2006120), the Swedish Council for Working Life and Social Research (FAS), the Spanish Ministry of Education (EX-2007-1124, and EX-2008-0641), and the Spanish Ministry of Health, Maternal, Child Health and Development Network (number RD08/0072) (JPRL, LAM)

An early Cretaceous pellet

Peer Reviewe

Brief Communications

We have discovered a mass of fossil bones from four juvenile birds at Las Hoyas in Cuenca, Spain, which show signs of having been digested. To our knowledge, this rare finding of an Early Cretaceous fossil of an apparently regurgitated pellet provides the first evidence that Mesozoic birds were prey animals.Peer reviewe

The Atapuerca Sites and the Ibeas Hominids

ABSTRACT:The Atapuerca railway Trench and Ibeas sites near Burgos, Spain, are cave fillings that include a series of deposits, ranging from below the Matuyama/Bruhnes reversal up to the end of Middle Pleistocene. The lowest fossil-bearing bed in the Trench contains an assemblage of large and small Mammals including Mimomys savini, Pitymys gregaloides, Pliomys episcopalis, Crocuta crocuta, Dama sp, and Megacerini; the uppermost assemblage includes Canis lupus, Lynx spelaea, Panthera (Leo) fossilis, Felis sylvestris, Equus caballus steinheimensis, E. c. germanicus, Pitymys subterraneus. Microtus arvalis agrestis, Pliomys lenki, and also Panthera toscana, Dicerorhinus hemitoecbus, Bison schoetensacki, which are equally present in the lowest level. The biostratigraphic correlation and dates of the sites are briefly discussed, as are the paleoclimatic interpretation of the Trench sequences. Stone artifacts are found in several layers; the earliest occurrences correspond to the upper beds containing Mimomys savini. A set of preserved human occupation floors has been excavated in the top fossil-bearing beds. The stone-tool assemblages of the upper levels are of upper-medial Acheulean to Charentian tradition. The rich bone breccia SH, in the Cueva Mayor-Cueva del Silo, Ibeas de Juarros, is a derived deposit, due to a mud flow that dispersed and carried the skeletons of many carnivores and humans. The taxa represented are, Ursus deningeri (largely dominant), Panthera (Leo) fossilis, Vulpes vulpes, Homo sapiens var. Several traits of both mandibular and cranial remains are summarized. Preliminary attempts at dating suggest that the Ibeas fossil man, is older than the Last Interglacial, or Oxygen-isotope stage 5.RESUMEN: La Trinchera del ferrocarril de Atapuerca y yacimientos de Ibeas cerca de Burgos, España, son rellenos de cuevas que incluyen una serie de depósitos, que datan desde por debajo de la inversión Matuyama/Bruhnes hasta el final del Pleistoceno Medio. El nivel fosilífero de la Trinchera contiene un conjunto de grandes y pequeños Mamíferos incluyendo Mimomys savini, Pitymys gregaloides, Pliomys episcopalis, Crocuta Crocuta, Dama sp. y Megacerini; el conjunto más superior incluye Canis lupus, Lynx spelaea, Panthera (Leo) fossilis, Felis sylvestris, Equus caballus steinheimensis, E. c. germanicus, Pitymys subterraneus, Microtus arvalis agrestis, Pliomys lenki y también Panthera toscana, Dicerorhinus hemitoechus, Bison schoetensacki, que están igualmente presentes en el nivel más inferior. La correlación bioestratigráfica y las edades de los yacimientos se discuten brevemente, al igual que la interpretación paleoclimática de las secuencias de Trinchera. Los artefactos de piedra se encuentran en varios niveles, las primeras apariciones corresponden a los niveles superiores que contienen Mimomys savini. Se ha excavado un conjunto de suelos que preservan ocupación humana en la parte superior de los niveles fosilíferos. Los conjuntos de herramientas de piedra de los niveles superiores son del Achelense superior-medio a la tradición Charentiense. La rica brecha fosilífera SH, en la Cueva Mayor-Cueva del Silo, Ibeas de Juarros, es un depósito derivado, debido a un flujo de lodo que dispersó y transportó los esqueletos de muchos carnívoros y humanos. Los taxones representados son, Ursus deningeri (muy predominante), Panthera (Leo) fossilis, Vulpes vulpes, Homo sapiens var. Se resumen los rasgos de los restos mandibulares y craneales. Los intentos preliminares de datación sugieren que el hombre fósil de Ibeas, es más antiguo que el último Interglacial, o estadio de oxígeno isotópico 5.Peer reviewe

Objectively measured and self-reported leisure-time sedentary behavior and academic performance in youth: The UP&DOWN Study

The objective of this study was to examine the associations of objectively measured and self-reported sedentary behavior during leisure time with academic performance and patterns of sedentary behavior with academic performance. This study was conducted with 1146 youth aged 12.5 ± 2.5 years in Spain during 2011–2012. Leisure-time sedentary behavior during out-of-school hours was assessed by accelerometry and self-report. Academic performance was assessed through school grades.Evaluación de la interacción entre genética y actividad física en el estado físico y la salud en escolares y adolescentes con Síndrome de Down: estudio de seguimiento a tres años Plan Nacional de I+D+i.

Perceived environment in relation to objective and self-reported physical activity in Spanish youth. The UP&DOWN study

The aims of the present study were to assess the association of environmental perception with objective and self-reported physical activity (PA) and the relation between environmental perception and meeting PA recommendations on children and adolescents. A sample of 1520 youth (770 boys) aged 8-18 years (12.1 ± 2.5 years) from the UP&DOWN study were included in the data analyses. Environmental perception was assessed with the short adapted version of the ALPHA environmental questionnaire. PA was objectively (accelerometers) and self-reported measured (PA Questionnaire for Children, Patient-centered Assessment and Counseling for Exercise Questionnaire and Finnish PA Index). Linear regression models were used to assess the association of environmental perception with PA. Bivariate logistic regression models were used to assess differences between environmental perception and meeting PA recommendations. Environmental perception was positively associated with both objective and self-reported PA. Some differences were found in the association of environmental perception and PA between sex-and age-specific groups. Youth who perceived a more favourable environment were more likely to meet PA recommendations (at least 60 min · day− 1 of moderate to vigorous PA (MVPA)). Results suggest that environmental perceptions of children and adolescents may play an important role in achieving higher levels of PA.Plan Nacional de I+D+I MICINN (DEP 2010-21662-C04- 00)2.539 JCR (2016) Q2, 17/81 Sport Sciences1.280 SJR (2016) Q1, 31/280 Orthopedics and Sports Medicine, 18/195 Physical Therapy, Sports Therapy and Rehabilitation, 29/127 Sports ScienceNo data IDR 2016UE
