Adaptations to blood-feeding life style include behavioral traits, fundamental for host location, anatomical features, often including specialized mouthparts and biochemical specialization, with the production of complex secretions (generally including molecules acting as anti-hemostatic, anesthetic and anti-inflammatory) in specialized glands [ 2, 3].
In the recent past, their diversity was significantly greater, with 17 extinct species sharing body proportions and specializations with lorises and various non-primates, such as tree sloths, giant ground sloths, koalas, and striped possums (genus Dactylopsila).
The other factors are then extracted in turn and sorted by decreasing order of specialization, with the first few factors generally containing most of the relevant information.
We have taken exchange and specialization to the global limit, with systems of finance and governance so complex that they are difficult to manage.
Numerous studies investigated the phenomenon that increasing morphological complexity is correlated with increasing modularity and specialization of the underlying regulatory apparatus.
This figure shows a dendrogram calculated by the Ward method, using composition ratios and specialization coefficients of the comparison with JEGM and SDGM, and percentages of landslide masses (Table 1).
We thought that hierarchical clustering, using composition ratios and specialization coefficients of the comparison with thematic maps or data, was adequate to understand the similarity of the clusters.
We performed hierarchical clustering using composition ratios and specialization coefficients from the comparison with geological and geomorphological maps and used percentages of landslide masses to assist grouping.
For the years since the survey year 2005, it is possible to reconstruct the workforce's initial vocational qualification by matching workers' specializations with the appropriate occupational classifications and formal qualification levels [ 10].
We construct a theoretical model that captures the tradeoff between multiskilling (which gives greater flexibility to reassign workers in production) and specialization (which provides workers with the expertise to respond to product market signals in their area of specialty).
