The problem of the species concept in the phylogeny of the cave bears
(Universidade da Coruña, 2001)[Abstract] This a short review of a series of concepts daily used in palaentology, trying to connect them with their meaning in other fields of study in Biology. Firstly, it should be pointed out if the concept of species ... -
A review of the cave bear sex dimorphism
(Universidade da Coruña, 2001)[Abstract] In this paper the influence of sex dimorphism in the population of cave bears from Cova Eirós (Triacastela, Galicia, Spain) is reviewed. The study will be centred in the skull, jaw and teeth, and principally in ... -
Dental wear and grit ingestion in extant and extinct bears from Northern Spain
(Universidade da Coruña, 2001)[Abstract] The dental morphology of the cave bear Ursus spelaeus (Rosenmuller & Heinroth, 1794) indicates its specialisation as a vegetation eater. Although vegetal matter plays also an important role in the diet of most ... -
Dependencia espacial de datos topográficos a escala de ladera y pequeña cuenca agrícola
(Universidade da Coruña, 2001)[Abstract] Landscapes are characterized by both, random and non-random variability components. Random variability of topographical data, summarized by the semivariance, may be used to elaborate DEMs. The main objective of ... -
Análisis geoestadístico de la microtopografía de la superficie en un suelo de cultivo
(Universidade da Coruña, 2001)[Abstract] Depressions at the soil surface influence temporal water storage and hence runoff generation. Surface microtopography of tilled soils is subject to spatial and temporal changes. The objective of this study was ... -
Disponibilidad de macro- y micronutrientes en un suelo de cultivo de Mabegondo (A Coruña)
(Universidade da Coruña, 2001)Abstract] The Mehlich–3 extraction reagent recommended for use on a wide range of acid soil types was utilised for extracting in a simple step, both major elements (P, Ca, Mg) and micronutrients (Fe, Mn, Cu and Zn,). The ... -
Efectos del encalado sobre los cambios físico-químicos y químicos en suelos inundados
(Universidade da Coruña, 2001)Rice growth in wetlands or paddy soils is economically important in Latin America.Lime amendment is becoming a conventional practice for rice production in this area. A field study was conducted to compare changes induced ... -
Description of pathological conditions in the skeleton of an adult male brown bear Ursus arctos from the Cantabrian range of mountains (Reserva Nacional de Caza de Riaño, León)
(Universidade da Coruña, 2001)[Abstract] In this paper we describe with detail the pathological conditions found on the skeleton of an adult male brown bear from the Cantabrian Mountains. This specimen shows a great number of pathologies, some of ... -
Efecto de las propiedades hidráulicas del suelo sobre la respuesta hidrológica calculada por LISEM 5.0
(Universidade da Coruña, 2001)[Abstract] LISEM model (Limburg Soil Erosion Model) is actually being developped in order to perform dynamic simulations of surface runoff and erosion in catchments. This model is also proposed as analysis support system ... -
Identification of ambiguous fossil bone remains following 13C and 15N isotopic signals on bone collagen
(Universidade da Coruña, 2001)[Abstract] In this paper we deal with an useful application of isotopic studies on fossil bone remains. Following δ1 3C and δ1 5N signals recorded in bone collagen, it is possible to classify into the proper taxon some ... -
Descripción y puesta a punto de un simulador de lluvia de campo para estudios de escorrentía superficial y erosión del suelo
(Universidade da Coruña, 2001)[Abstract] The present paper describes the design, construction, calibration and operation of a spray rainfall simulator . The design of the plots used for the purpose of this study is also described in order to determine ... -
Análisis microestructural de caolinitas y génesis de caolines en el Macizo Ibérico
(Universidade da Coruña, 2001)[Abstract] Mineralogical, geochemical and XRD microstructural characterization for different groups of argillized materials of the Iberian Massif have been performed; the variability and correllation of these characteristics ... -
The Evolution of Metapodial Bones in the Cave Bear Group and its biostratigraphical Implications
(Universidade da Coruña, 2001)[Abstract] A short description of the methods is followed by some central results obtained from the analyses of metapodial bones in the cave bear group from sites in Austria and Italy. The evolution of metapodials shows, ... -
Reflections on the fate of some geomorphological ideas
(Universidade da Coruña, 2001)[Abstract] In geomorphology, as in other sciences, investigation is concerned with the collection and characterisation of data, and the generation and testing of working hypotheses. Considering the analysis of landforms ... -
Preliminary report on sediments from Pocala Cave: sedimentological and heavy mineral analysis
(Universidade da Coruña, 2001)[Abstract] In 1999 two borings were performedin the area of Pocala Cave, one outside the cave and the other inside in the cave. In particular four samples of the first boring were studied.It seems that mineralogy is strictly ... -
The wolverine (Gulo gulo L.) in Spain – one of the south most spreading during the Pleistocene
(Universidade da Coruña, 2001)[Abstract] This paper is a contribution to the study of the wolverine (Gulo gulo ) in Europe. The scarce findings of this species in the Iberian Peninsula are described and metrically compared with those living representants ... -
Phylogenetic Problems of the Alpine Cave-Bears
(Universidade da Coruña, 2001)[Abstract] The metric and morphological characteristics of 23 alpine cave bear fauna are been studied and compared with the normal lowland form. The phylogenetic conclusions are drawn: 3 new subspecies? -
Cave bear's diet: a new hypothesis based on stable isotopes
(Universidade da Coruña, 2001)[Abstract] The Ursus spelaeus diet has always been a controversial topic in Paleontology. Both, morphometric and isotopic studies, have raised the hypothesis of herbivorism for this extinct ursid that belongs to the order ... -
Pleistocene small cave bear (Ursus rossicus) from the South Siberia, Russia
(Universidade da Coruña, 2001)[Abstract] The skull, mandibles and cheek teeth of U. Rossicus from four localities of the South Siberia are examined. This species inhabited the steppe regions in early Middle and Late Pleistocene. By odontological ... -
Cave bear worship in the Palaeolithic
(Universidade da Coruña, 2001)[Abstract] As a result of detailed discussion under different points of view, this study has neither endorsed evidence of any early belief system nor of cave bear worship. All relevant conceptions of that kind are either ...
