X-chromosomal STRs: Metapopulations and mutation rates
Gusmão, L.; Antão-Sousa, S.; Faustino, M.; Abovich, M.A.; Aguirre, D.; Alghafri, R.; Alves, C.; Amorim, A.; Arévalo, C.; Baldassarri, L.The analysis of STRs located on the X chromosome has been one of the strategies used to address complex kinship cases. Its usefulness is, however, limited by the low availability of population haplotype frequency data and lack of knowledge on the probability of mutations. Due to the large amount of data required to obtain reliable estimates, it is important to investigate the possibility of grouping data from p...

Contribuição para o estudo revisto e ampliado da produtividade numérica (Pn) da...
Oliveira, António; Guerreiro da Silva, P.; Carvalho da Silva, M.; Faustino, M.Na sequência de trabalhos de investigação e de demonstração experimental levados a cabo na Her¬dade Agro-pecuária da Escola Superior Agrária do Instituto Politécnico de Beja. durante o periodo de 2006 a 2009, sobre o tema em estudo, procedemos à introdução e acompanhamento do varrasco Alenle- jano mamilado nas varas com acasalamento contro¬lado, cujos resultados dos nossos ensaios relativos à produtividade numé...
Thyroid hormones in growth and development of fish
Power, Deborah; Llewellyn, Lynda; Faustino, M.; Nowell, M. A.; Björnsson, Björn Thrandur; Einarsdóttir, Ingibjörg E.; Canario, Adelino V. M.The thyroid hormones (THs), thyroxine (T4) and triiodothyronine (T3) are products of the thyroid gland in all vertebrates. Their role in early development and metamorphosis is well established in mammals and amphibians, respectively, and recently several studies in fish have highlighted the importance of THs during flatfish metamorphosis. THs are present in high quantities in fish eggs and are presumably of mat...
Osteologic development of the viscerocranial skeleton in sea bream A lternative...
Faustino, M.; Power, DeborahThe ontogeny of the viscerocranial skeleton of sea bream Sparus aurata larvae was studied from 1 to 90 days post-hatching. In the smallest specimens analysed at 2·7 mm LN no cephalic elements were present and at 3·1 mm LN the following cartilaginous structures were visible: trabecula cranii, auditory capsule, Meckel’s cartilage, quadrate, hyosymplectic cartilage, sclerotic, hypohyal, ceratohyal epihyal cartilag...
Thyroid hormones in sea bream larval development
Power, Deborah; Llewellyn, Lynda; Faustino, M.; Nowell, M. A.; Björnsson, Björn Thrandur; Einarsdóttir, Ingibjörg E.; Canario, Adelino V. M.The thyroid hormones (TH), thyroxine (T4) and triiodothyronine (T3) are a product of the thyroid gland in all vertebrates. The hormones are pluripotent and in vertebrates are involved in growth, differentiation, metamorphosis, reproduction and metabolism. THs are secreted from the thyroid gland, circulate bound to thyroid hormone-binding proteins and exert their biological effects by binding to specific nuclear...
Development of the pectoral, pelvic, dorsal and anal fins in cultured sea bream
Faustino, M.; Power, DeborahThe pectoral fin girdle was the first element of the fins to develop in Sparus aurata. By 3·1mm LN (notochord length) the cleithrum was ossified and the cartilaginous caracoid–scapula was present. The fin was fully developed at 11·6 mm LS (standard length) and by 16·0 mm LS most elements of the fin were ossified. The pelvic fins were the last pair to develop and rudiments of these were first detected at 7·9 mm ...
Development of osteological structures in the sea bream Vertebral column and ca...
Faustino, M.; Power, DeborahThe development of cartilaginous structures in cultured sea bream Sparus aurata larvae and the timing of their ossification was studied. In cultivated sea bream larvae the first cartilaginous structure to be identified was hypural 1 at 4·1 mm notochord length (LN). By 5·3 mm LN, prior to the onset of ossification, it was possible to distinguish the following cartilaginous structures: all 23 neural arches, all 1...
Identification of bone gla protein during early development of Solea Senegalensis
Gavaia, Paulo J.; Faustino, M.; Cancela, LeonorWith the objective of better understanding the calcification processus in the Sole (Solea senegalensis) we have followed the appearance of cartilage and bone structures during the sole early developmental stages (from hatching till 51 days post-Hatching-DPH) by a specific double labelling method (Alcin blue/Alizarin red).
