متن کاملCharacter combinations, convergence and diversification in ectoparasitic arthropods.
Different lineages of organisms diversify over time at different rates, in part as a consequence of the characteristics of the species in these lineages. Certain suites of traits possessed by species within a clade may determine rates of diversification, with some particular combinations of characters acting synergistically to either limit or promote diversification; the most successful combina...
متن کاملGeographic and Product Diversification Facilitating an Improper Distribution of Wealth
This paper is aimed to show evidence about unbalanced wealth distribution in Mexico, affording more information, knowledge and sensitivity from citizens and Mexican government on behalf of looking for an equitable economic development and increasing the national welfare are the objective from this investigation. Across the assumption: “The growth of FEMSA from geographical and product diversifi...
متن کاملUsing occupancy models to investigate the prevalence of ectoparasitic vectors on hosts: An example with fleas on prairie dogs☆
Ectoparasites are often difficult to detect in the field. We developed a method that can be used with occupancy models to estimate the prevalence of ectoparasites on hosts, and to investigate factors that influence rates of ectoparasite occupancy while accounting for imperfect detection. We describe the approach using a study of fleas (Siphonaptera) on black-tailed prairie dogs (Cynomys ludovic...
متن کاملDiversification of ectoparasite assemblages and climate: an example with fleas parasitic on small mammals
Aim We studied the relationships between the numbers of species and numbers of higher taxa (genera, tribes, subfamilies and families) in flea assemblages of small mammalian hosts with the aims of: (a) comparing these relationships across different regions, and (b) testing the hypothesis that flea assemblages in warmer regions diversify mainly via intrahost speciation, whereas those in colder re...
