Abstract Our objective was to quantify the relationship between seasons of the year, milk production, and milk composition of a dairy farm based on data for 48 consecutive months, using multivariate statistical analyses. The dataset contained information on productive indexes and milk composition from the bulk tank milk, which was measured from milk samples, collected monthly and used to determine the total dry extract and defatted dry extract, lactose, fat, protein, somatic cell count, and total bacterial count. Seasons of the year and milk production/hectare were also considered. Factor, cluster, and discriminant analysis were used to study the relationships between the above-mentioned variables. A positive relationship was noted between season and total... |

INTRODUCTION: The South American country Chile now boasts a life expectancy of over 80 years. As a consequence, Chile now faces the increasing social and economic burden of cancer and must implement political policy to deliver equitable cancer care. Hindering the development of a national cancer policy is the lack of comprehensive analysis of cancer infrastructure and economic impact. OBJECTIVES: Evaluate existing cancer policy, the extent of national investigation and the socio-economic impact of cancer to deliver guidelines for the framing of an equitable national cancer policy. METHODS: Burden, research and care-policy systems were assessed by triangulating objective system metrics -epidemiological, economic, etc. - with political and policy analysis.... |

Although ecological research is progressing rapidly, the answers to certain key questions continue to elude us. This paper considers several of the contemporary challenges facing ecology. (1) Terminology is voluminous and often poorly defined, resulting in inefficient communication. (2) The concept of scale affects our inferences about system structure and function, requiring us to continue an almost heuristic investigation of breaks, domains, and integration. New tools that more explicitly incorporate scalar issues will need to be developed for progress to take place in the field of ecology. (3) Increasingly, it is expected that applied questions will be solved in less than a year. This demand for solutions from ecologists often produces short-term and... |

Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find... |

Since the Convention on Biological Diversity in 1992, biodiversity has become an important topic for scientific research. Much of this research is focused on measuring and mapping the current state of biodiversity, in terms of which species are present at which places and in which abundance, and making extrapolations and future projections, that is, determining the trends. Biodiversity databases are crucial components of these activities because they store information about biodiversity and make it digitally available. Useful biodiversity databases require data that are reliable, standardized, and fit for up-scaling. This paper uses material from the EBONE-project (European Biodiversity Observation Network) to illustrate how biodiversity databases are... |

Resumo: Num país com as dimensões do Brasil é muito acentuada a variabilidade dos sistemas de produção agropecuária praticados pelos produtores. Conhecer esta diferenciação é fundamental para propor linhas de pesquisa, desenvolvimento, transferência de tecnologia e políticas públicas apropriadas. Dados do Censo Agropecuário brasileiro de 2006, realizado pelo Instituto Brasileiro de Geografia e Estatística (IBGE), mostram que mais da metade dos estabelecimentos agropecuários do país possuíam pelo menos um bovino, correspondendo a 2,7 milhões de estabelecimentos e 176,1 milhões de cabeças. Este trabalho trata da classificação e caracterização dos municípios produtores de bovinos no Brasil, empregando técnicas de análise multivariada (análise fatorial e de... |

Blue marlin is fished in the French Antilles around Fish Aggregating Devices (FADs). This fishery commenced in late 1985 and the fishing fleet reached its full potential in the second half of the 2000s. A fisheries information system (SIH), implemented from 2008, enables good estimation of catches and effort around FADs. The data on catch estimates of blue marlin and associated fishing effort are presented herein, as well as the methods used to assess them. From these and a survey of fishing masters, it is possible to reconstitute, year by year, the fishing fleet working around FADs in the French Antilles and to reconstitute a historical series of blue marlin landing. |

In August 2005, Ifremer launched its institutional repository: Archimer. Today, Archimer provides free access, on the Internet, to more than 5,000 documents, including more than 80 % of the publications co-written by Ifremer since the creation of the repository. Following a reminder of the publication harvesting and recording methods, this document assesses the use of Archimer. It analyses, amongst others, the progression of the number of interrogations and the differences observed between the uses of the different types of works (publication, thesis, internal reports...). This study also demonstrates the predominance of the search engine Google in the access to the documents and underlines its consequences in terms of Internet visibility. |
