Temporal spatial distribution of benthic meiofauna in four beaches of the northern Havana shore

The temporal-spatial distribution of benthic meiofauna was evaluated in four beaches at the north coast of Havana, Cuba, from March 2003 to February 2004. We studied two urban beaches (Santa Fe and La Concha) and two tourist beaches (Mar Azul and Canasi). Monthly meiofauna samplings were taken by scuba-diving using with a syringe (inner diameter 2.5 cm), and physico-chemical parameters (grain size, interstitial salinity and water column salinity were recorded with standard equipment). Statistical analysis (MDS and ANOSIM) were performed. Depth and biotope kind were the same in the four beaches. Highest densities were obtained in Santa Fe (7,133.48 ind/10 cm2) while the lowest mean densities were found in Canasí (892.12 ind/10 cm2). We recorded 13 taxa; the dominant organisms in Santa Fe and Mar Azul were free-living marine nematodes. Copepods were the dominant organisms in La Concha and Canasí.

The European Proteomics Association (EuPA) is in the field. Report of the formal inauguration of the European Proteome Association (Munich, Germany, August 29, 2005)

After one year of preparation the European Proteomics Association (EuPA) was formally inaugurated on August 29, 2005, on the occasion of the 4(th) HUPO World Congress in Munich, Germany. Delegates from 16 European countries elected Dr. Friedrich Lottspeich, President of the German Proteome Society, as the first EuPA President. The EuPA Board also comprises Professor Mathias Uhlen as Vice President, along with Professor Michael Dunn (Ireland), Professor Concha Gil (Spain), Dr. Jean Charles Sanchez (Switzerland) and Professor Pier Giorgio Righetti (Italy) as Coordinators for the presently defined focus activities of the EuPA. The general objectives of the EuPA are to promote proteomic activities throughout Europe, emphasising the benefits and contribution of proteomics to biological researchers, industry, the general public and politicians.     

Ancestral matrilineages and mitochondrial DNA diversity of the Lidia cattle breed

To clarify the genetic ancestry and the mitochondrial DNA (mtDNA) diversity of the Lidia cattle breed, a 521-bp D-loop fragment was sequenced in 527 animals belonging to 70 herds distributed across 29 lineages. The mtDNA diversity recorded was similar to that seen for Middle Eastern breeds and greater than that recorded for the majority of European breeds. Haplotype T3 was the most common (81%), followed by the African T1 haplotype (17%); very low frequencies were recorded for haplotypes T and T2. The results agree with there being two major ancestral lines for the Lidia breed, European and African, similar to that seen for other Mediterranean breeds. A wide range of variation in haplotype frequencies was seen between the examined lineages. Haplotype T3 was present in all those analysed; in five it was the only one present, and in only one lineage (Miura) was its frequency lower than that of T1. T1*, a haplotype reported in Criollo breeds and to date in only a single European breed (the Retinta breed from Spain), was found in a single animal belonging to the Concha y Sierra lineage. Network analysis of the Lidia breed revealed the presence of two major haplotypes: T3 and T1. The Lidia breed appears to be more closely related to prehistoric Iberian and Italian than to British aurochs.     

Human ears grow throughout the entire lifetime according to complicated and sexually dimorphic patterns--conclusions from a cross-sectional analysis

In most of its anatomical constituents, e.g. in the Helix, etc., the external human ear is homologous to that of all Primates and Scandentia (tree shrews). Thus, its genetic basis is largely older than 60 Mio yrs. Based upon the observation of lifelong growth of the ear (e.g. Montacer-Kuhssary 1959), we aimed to elucidate the growth of the human ear in a more detailed way throughout life and in both sexes. On standardized photographical material collected randomly in Berlin (Germany), we measured N = 1448 ears from neonate children to volunteers of 92 yrs in age. 10 longitudinal measurements and 5 further anatomical parameters yielded a data set of roughly 19,000 data in total. Based upon our cross-section analysis, we quantified several sexual dimorphisms. Furthermore, we deduced ontogenetic developments and, partially, corrected their proportions for secular acceleration and body height shrinking with age. At the time of birth, in proportion to the body, the external ear was even bigger than the large head and continued growing rather linearly throughout life, reaching the highest average lengths in the volunteers aged over 85 yrs. The large yearly increases during childhood began to diminish at as early an age as 8 or 10 yrs. In all parameters where post adult growth was observed, female ears showed a lesser increase than those of men. The greatest ear length in females was 52 mm (SD +/- 4.3 mm) at birth, 61 mm (SD +/- 3.9 mm) at around 20 yrs of age and 72 mm (SD +/- 4.6 mm) in women older than 70 yrs. For the male subjects, these three values were: 52 mm (SD +/- 4.1 mm), 65 mm (SD +/- 4.0 mm) and 78 mm (SD +/- 4.8 mm), respectively. In spite of extreme premature growth of the auricle and its further lifelong growth, three anatomical features of the ear did practically not grow at all after birth: the width of the Concha auriculae and of the Incisura intertragica, as well as the diameter of the helical brim of the auricle. The problems arising concerning the functions and selective values of all these very unusual proportions and growths are discussed. The ontogenetic development of one or more pretragal skin folds could be used as a contribution to age estimations in forensic anthropology.
