  1. Sexual preferences for songs in female domestic canaries ( Serinus canaria): can late song exposure, without social reinforcement, influence the effects of early tutoring?

    Depraz, Violaine; Kreutzer, Michel; Leboucher, Gérard
    We studied the relative effects of early and late song exposure without social reinforcement on female sexual preferences in the domestic canary ( Serinus canaria). Young female canaries were tape-tutored during their first 4 months of life with songs of either domestic or wild male canaries (DT and WT conditions). When they reached sexual maturity, these females were placed in breeding conditions and some of them were re-exposed to songs. During this “late exposure” the females, according to their experimental group, were either presented with new domestic or wild songs (DL and WL conditions) over 40 days, or were kept without song...

  2. Population genetics of Glutathione peroxidase (GPX1) in Central Portugal

    Carvalho, M.; Amorim, A.
    Abstract The isoenzymes of red cell glutathione peroxidase (GPX1) was investigated in the population of Central Portugal. A variant of GPX1 with mobility consistent with GPX1*2 was detected with a frequency of: GPX1*2=0,005 (N=221).

  3. Human remains from the artificial cave of São Pedro do Estoril II (Cascais, Portugal)

    Silva, Ana
    Abstract The present paper gives the results of the anthropological study of the human remains from the artificial cave of So Pedro do Estoril II (2300–2500 B.C.). These chalcolithic remains were fragmentary and incomplete, which made their analysis difficult.

  4. The three oralTori in the Coimbra population (Portugal) at the beginning of the XXth century A.D.

    Galera, V.; Garralda, M.; Casas, M.; Cleuvenot, E.; Rocha, M. A. T. da
    The remarkable anthropological series formed by E. Tamagnini at the Universidade de Coimbra consists of the exhumed human remains from “La Conchada” cemetery, in Coimbra (Northern Portugal). From this collection, only those individuals coming from the different districts of Coimbra, where they also lived and died, were selected for study. The resulting series was made of by 483 individuals: 234 women and 249 men. The personal data sheets indicate that these people died between 1910 and 1938; their professions, age at death and its cause are also noted. They can be considered as a relatively homogeneous group of low socioeconomical...

  6. Female and male serins ( Serinus serinus ) respond differently to derived song traits

    Cardoso, Gonçalo; Mota, Paulo; Depraz, Violaine
    Abstract We tested if male or female behavior towards manipulated song indicates intra- or inter-sexual selection of two characteristics of serin song that are extreme and evolutionarily derived in this species: high frequency and fast syllable rate. In a first experiment, we monitored vocal responses and attendance to song playbacks. Female behavior indicated a preference for high-frequency song and suggested an aggressive function for fast syllable rates, as fast songs inhibited vocal response. Males did not show discrimination of frequency or syllable rate with this experimental design. The second experiment used a simple approach/no approach design, and in this experiment,...

  7. Exchanged identities in a complex multiple homicide case. Identification and cause of death

    Cunha, Eugénia; Pinheiro, João; Pinto-Ribeiro, Isabel; Vieira, Duarte
    Abstract We report a multiple homicide in Angola involving six Portuguese citizens. Immediately after the crime, four bodies were retrieved from the homicide site. Forensic autopsies were allegedly performed by local doctors and three bodies were transferred to Portugal, where they were buried with no extra expertise, presumably identified only by the examinations carried out in Angola. The two remaining bodies, presumably from sub-adults, were only discovered 1 year later. At that time, some bone samples of these two corpses were sent to Portugal. A multidisciplinary team of the National Institute of Legal Medicine (NILM) in Portugal, including forensic anthropologist...

  8. Distribution of AMY2 polymorphism in S. Tomé and Príncipe (West Africa)

    Manco, L.; Trovoada, M.; Abade, A.; Amorim, A.
    Abstract The genetic polymorphism of AMY2 was studied in the population of S. Tom and Prncipe (West Africa) using agarose gel electrophoresis. AMY2 frequencies are reported for the first time in a subSaharian population. The gene frequencies found were: AMY2*1=0.948, AMY2*3=0.052 (N=173).

  9. The construction of sex discriminant functions from a large collection of skulls of known sex

    Cunha, E.; van Vark, G.
    Abstract The suitability of the large collection of skulls of known sex (n?=357, n?=213), housed in the Department of Anthropology of the University of Coimbra, as a reference series for sex diagnosis from skulls, was investigated. This was done by calculating estimates for the maximum actual discriminatory value for samples being diagnosed. here called Dt max. The estimates for this statistic were found to be relatively low. Depending on the estimation procedure used, values of 1.68 and 1.64, were obtained, which correspond with theoretical percentages of correct classification of 79.8 and 79.3, respectively. An attempt was then made to investigate...

  10. Social background and age at menarche in Portuguese university students: A note on the secular changes in Portugal

    Padez, C.
    Menarcheal age of a sample of Portuguese university students (n = 3,366), born between 1972 and 1983, age 18-23 years, was analyzed. The influence of parents' educational level and occupation, family size, birth order, and degree of urbanization of girl's locality of residence during childhood and adolescence were analyzed as well as secular trend in the Portuguese population. Mean age at menarche for girls born in 1983 was 12.32 years. Parents' educational level and occupation did not show any significant influence on mean age at menarche. Place of residence during childhood years and adolescence showed a significant effect on mean...

  11. Prevalence of overweight and obesity in 7-9-year-old Portuguese children: Trends in body mass index from 1970-2002

    Padez, C.; Fernandes, T.; Mourão, I.; Moreira, P.; Rosado, V.
    The aim of this study was to assess the prevalence of overweight and obesity in Portuguese children age 7-9 years and to analyze trends in body mass index (BMI) from 1970-2002. Data were collected from October 2002 to June 2003 in a random sample of Portuguese children. Height and weight were measured and BMI (Kg/m2) was calculated. The International Obesity TaskForce (IOTF) cutoffs to define overweight and obesity were used. In the total sample we found 20.3% of overweight children and 11.3% of obese children. These results indicate a prevalence of overweight/obesity of 31.5%. Girls presented higher percentages of overweight...

  12. Analysis of TPI gene promoter variation in three sub-Saharan Africa population samples

    Manco, Licínio; Machado, Patrícia; Lopes, Dinora; Nogueira, Fátima; Rosário, Virgílio E. Do; Alonso, Pedro L.; Varandas, Luís; Trovoada, Maria De Jesus; Amorim, António; Arez, Ana Paula
    Population samples from Angola, Mozambique, and S. Tomé e Príncipe were screened for the TPI gene promoter variants -5ArarrG, -8GrarrA and -24TrarrG. Three haplotypes were identified in the three populations: the haplotype -5A-8G-24T (average frequency 65.3%) and two less common haplotypes -5G-8G-24T (average frequency 24.7%) and -5G-8A-24T (average frequency 10.0%). A population sample from Central Portugal showed the haplotype -5A-8G-24T in 139 chromosomes and one subject heterozygous for haplotype -5G-8A-24G. The exact test of sample differentiation among three groups of malaria-infected individuals classified according to the severity of the disease showed no significant differences. We confirmed TPI gene diversity in...

  13. Enamel hypoplasias and physiological stress in the Sima de los Huesos Middle Pleistocene hominins

    Cunha, E.; Rozzi, F. Ramirez; Castro, J. M. Bermúdez De; Martinón-Torres, M.; Wasterlain, S. N.; Sarmiento, S.
    This study presents an analysis of linear enamel hypoplasias (LEH) and plane-form defects (PFD) in the hominine dental sample from the Sima de los Huesos (SH) Middle Pleistocene site in Atapuerca (Spain). The SH sample comprises 475 teeth, 467 permanent and 8 deciduous, belonging to a minimum of 28 individuals. The method for recording PFD and LEH is discussed, as well as the definition of LEH. The prevalence of LEH and PFD in SH permanent dentition (unilateral total count) is 4.6% (13/280). Only one deciduous tooth (lower dc) showed an enamel disruption. Prevalence by individual ranges from 18.7-30%. The most...

  14. A case of Os odontoideum in the palaeopathological record

    Curate, F.
    Os odontoideum is an uncommon abnormality of the second cervical vertebra, the aetiology of which is contentious. Whether congenital or acquired, the condition often results in atlantoaxial instability and subsequent compression of cervical cord or vertebrobasilar vessels. The bioarchaeological study of a medieval sample from the Christian necropolis of Cacela Velha (Algarve, southern Portugal) provided the opportunity to describe one of the first cases of this rare anomaly ever reported in the palaeopathological record.

  15. Scapular development from the neonatal period to skeletal maturity: A preliminary study

    Rissech, C.; Black, S.
    An understanding of the basic growth rates and patterns of development for each element of the human skeleton is important for a thorough understanding and interpretation of data in all areas of skeletal research. Yet surprisingly little is known about the detailed ontogenetic development of many bones, including the scapula. With the intention of describing the changes that accompany postnatal ontogeny in the scapula and algorithms to predict sub-adult age at death, this communication examines the development of the scapula through nine measurements (3 from the glenoidal area, 4 from the body and 2 related to the spinous process) by...

  16. Trends in adult stature of peoples who inhabited the modern Portuguese territory from the Mesolithic to the late 20th century

    Cardoso, H. F. V.; Gomes, J. E. A.
    This study documents long-term changes in stature from the Mesolithic to the late 20th century in the territory of modern Portugal. Data utilised originated from published sources and from a sample of the Lisbon identified skeletal collection, where long bone lengths were collected. Mean long bone lengths were obtained from 20 population samples and compiled into nine periods. Pooled long bone lengths for each period were then converted to stature estimates. Results show three major trends: (1) a slow increase in stature from prehistory to the Middle Ages; (2) a negative trend from the Middle Ages to the late 19th...

  17. Pathogenesis of apical periodontal cysts: guidelines for diagnosis in palaeopathology

    Dias, G. J.; Prasad, K.; Santos, A. L.
    Apical periodontal cysts are benign lesions developing in relation to the apices of non-vital teeth due to inflammatory response from the infective pulp. These are epithelium-lined bony cavities containing fluid. Despite being widely reported in medical/dental literature, this common condition is poorly diagnosed and documented in the archaeological literature. We aim to clarify the correct terminology, demonstrate bony manifestations at different stages of pathogenesis of chronic periapical dental lesions into granuloma and apical periodontal cysts, and to describe diagnostic criteria which would provide practical guidelines for the diagnosis of these conditions.Three identified skulls from the International Exchange Collection, housed in...

  18. A tale of two islands: population history and mitochondrial DNA sequence variation of Bioko and São Tomé, Gulf of Guinea

    Mateu, E.; Comas, D.; Calafell, F.; Pérez-Lezaun, A.; Abade, A.; Bertranpetit, J.
    The hypervariable segment I of the control region of the mtDNA was sequenced in 45 unrelated individuals from Bioko and 50 from São Tomé, two islands in the Gulf of Guinea that have had very different settlement patterns: Bioko was colonized around 10000 BP, while São Tomé was first settled by the Portuguese, who brought African slaves to the island. Two different patterns of sequence variation are evident and are also clearly a consequence of their very different demographic histories. The Bubi present a low genetic diversity and it is likely that the island was colonized by a small number...

  19. Age estimation of adolescent and young adult male and female skeletons II, epiphyseal union at the upper limb and scapular girdle in a modern Portuguese skeletal sample

    Cardoso, Hugo F. V.
    This study completes previously reported ages for timing of epiphyseal union in the postcranial skeleton in a recent sample, with data from the scapula, clavicle, humerus, radius, and ulna. A sample of 121 individuals between the ages of 9 and 29 (females = 65, males = 56) was derived from the Lisbon documented skeletal collection. Epiphyseal union was scored at 16 anatomical locations, using a three-stage scheme: 1) no union; 2) partial union; and 3) completed union, all traces of fusion having disappeared. In the upper limb, the epiphyses of the elbow are the first to fuse at around 11...

  20. A picture of tuberculosis in young Portuguese people in the early 20th century: A multidisciplinary study of the skeletal and historical evidence

    Santos, Ana Luísa; Roberts, Charlotte A.
    The aim of this study was to examine the evidence, and consider the differential diagnosis, for tuberculosis (TB) in juvenile individuals from early 20th century documented skeletons. There are 66 male and female juvenile individuals in the Coimbra Identified Skeletal Collection (CISC) with an age at death ranging from 7-21 years. The individuals died between 1904-1936 in different areas of Coimbra, Portugal. Eighteen of these individuals died from TB affecting different parts of the body. Thirteen (72.2%) showed skeletal lesions that may be related to this infection. Of the 48 individuals with a non-tuberculous cause of death, only 2 (4.2%)...
