| We described the spatial and seasonal variation of feeding habits of Oligoryzomys longicaudatus in four environments of the steppe-forest transition zone of Argentinean Patagonia. Composition of fecal pellets collected from live-trap captures was determined with microhistological techniques using an identifcation key of representative plants of our study areas. Fruits and seeds constituted 57.2% of O. longicaudatus diets, followed by foliage (26.8%) and arthropods (16.0%). Fruits and seeds, foliage parts, and arthropods were primarily found in individuáis from shrublands, forests, and peridomestic areas, whereas foliage predominated in pastures. Similarity Index revealed differences between pastures and the other environments. Diet in shrubland showed... |

| Chemosynthetic ecosystems have long been acknowledged as key areas of enrichment for deep-sea life, supporting hundreds of endemic species. Echinoderms are among the most common taxa inhabiting the periphery of chemosynthetic environments, and of these, chiridotid holothurians are often the most frequently observed. Yet, published records of chiridotids in these habitats are often noted only as supplemental information to larger ecological studies and several remain taxonomically unverified. This study therefore aimed to collate and review all known records attributed to Chiridota Eschscholtz, 1829, and to conduct the first phylogenetic analysis into the relationship of these chiridotid holothurians across global chemosynthetic habitats. We show that... |

| Most Rivulidae fishes are popularly known as annual fishes which live in ephemeral environments such as pools, that obligatorily dry out seasonally causing the death of adult individuals. They have unique biological characteristics such as small body size, early sexual maturation, continuous reproduction, an elaborated courtship behavior, and a great reproductive capacity among fishes. The rivulids are widely distributed in North, Central and South America. In this study, the diet and reproductive biology of Cynopoecilus melanotaenia was analyzed. A total of 263 specimens were collected and the analysis of 233 gastrointestinal contents revealed an invertivorous diet composed mainly of small crustaceans (Cladocera, Amphipoda, and Ostracoda) and immature... |

| The present research aimed to analyze the impact of opportunistic behavior and bounded rationality impacts in the forms of contract adopted by the Agricultural Consortium of Specialized Farms (C.A.F.E.). For that, a case study was accomplished with the objective to embrace the most important characteristics of the theme as well as its process of development. The theoretical reference that gave support to this study it was the Transaction Costs Economics (TCE). Through the analysis of the variables approached by TCE, more specifically the behavioral factors (bounded rationality, opportunism) and forms of contract, it was concluded that, in the case studied the existence of opportunism interferes in certain way in the trust increasing the transactional... |

| Modernity is usually thought as a complex society with clearly differentiated spheres of everyday life. It means, in particular, that economic rules do not interfere with the norms structuring political, social, scientific and other interactions. The complex, differentiated society sharply contrasts with a "small" and homogeneous "pre-modern" society. The process of modernization, i.e. differentiation of the spheres of everyday life, can take various forms. In an advanced country it relies on internal forces. Modernization in this context looks like an evolutionary, "bottom-up" development. In a backward country (Russia and Germany in the first half of the 20th century), modernization requires a strong governmental (from the top to the bottom)... |
