A sociedade do conhecimento impõe uma mudança de padrão no que diz respeito à instituição escolar, nomeadamente, deixa de ser uma escola de elites passando assim a responder às necessidades sociais. Consequentemente, e para dar resposta às necessidades emergentes, a escola tem vindo a (re) organizar-se. As mudanças operadas no sistema educativo cabo-verdiano não incidiram sobre a gestão e a administração dos Pó...
The silvo-pastoral systems of Iberia, the Portuguese Montados and Spanish Dehesas, are widely recognized today as being hotspots of farmland biodiversity and exponents of landscape multifunctionality. Such systems are fully dependent on agricultural management, thus its natural value and environmental qualities are closely related, not only to the high variability of the system components, but also to the press...
The high nature value (HNV) concept, proposed by the European Environment Agency, recognizes that specific farming systems support high biodiversity levels, mainly as a result of extensive management practices. The Portuguese montado is one of the most significant HNV systems in southern Europe. However, considering the great complexity characterizing these systems both in land management and in landscape struc...
The High Nature Value (HNV) classification of farm systems, proposed by the European Environment Agency, emerges as more relevant todaycentral in the preparation of the rural development programmenegotiation of the agri-environment and rural areas supportwithin the, on the CAP post-2013. HNV classification is applicable across all Europe and seeks to define objective criteria for identifying farm systems who su...
Cytogenetic analysis of Astylus antis using mitotic and meiotic cells was performed to characterize the haploid and diploid numbers, sex determination system, chromosome morphology, constitutive heterochromatin distribution pattern and chromosomes carrying nucleolus organizer regions (NORs). Analysis of spermatogonial metaphase cells revealed the diploid number 2n = 18, with mostly metacentric chromosomes. Meta...
In this study, we investigated the analgesic activity of crude aqueous and methanol extracts obtained from Abarema cochliacarpos bark in mice, and analyzed its phytochemical profile. All the extracts exhibited analgesic properties against the writhing test in mice, but the aqueous and methanol extracts were more active, and more potent than two known analgesic and anti-inflammatory drugs used as reference. They...
Apresentamos uma pesquisa de avaliação de como famílias que foram intimadas e encaminhadas pela Justiça participam nos Grupos Multifamiliares. As famílias integradas nesses grupos passaram pelo estudo psicossocial em função de terem uma criança ou adolescente em situação de abuso sexual. Vinte e oito famílias foram contatadas, mas somente conseguimos entrevistar oito. Nosso objetivo foi enfocar a relação desenv...
In this work we describe the cytogenetic analyses performed in specimens of Astylus variegatus (Germar, 1824) collected in two localities: one area of natural vegetation and one of agricultural crops, where agrochemical products were used. Astylus variegatus had karyotypes with 2n(male) = 16+Xy p and 2n (female) = 16+XXp, with exclusively metacentric chromosomes. Pachytene spermatocytes showed synapsed autosoma...
Species of the subtribe Oedionychina not only have a highly uniform diploid number of 2n = 22 (20+X+y) but have the karyotypic peculiarity of possessing extremely large sex chromosomes. We analyzed Paranaita opima embryos and gonadal cells to determine their diploid number, chromosomal morphology, type of sex determination system, constitutive heterochromatin pattern and which chromosomes bear nucleolus organiz...
We used differential staining techniques (BSG, GTG, AgNO3, DAPI and CMA3 banding) and fluorescent in situ hybridization (FISH) with 5S and 18S probes to investigated the karyotypic and cytogenetic chracteristics of Prochilodus lineatus specimens from a population in Vila Velha state park (Parque Estadual de Vila Velha, Ponta Grossa, Paraná state, southern Brazil). The specimens studied showed the same karyotype...
