The starting point of this thesis is the understanding of the theoretical perspective of the new institutionalism of the rational choice that the behavior of the parties can be considered an optimal adaptation to an institutional environment. We sought to demonstrate that the American foreign policy was set up after the end of the Cold War as a game (considering one arena) or a set of games (considering multiple arenas), restricted to only two parties, within a space of competition in which they employ centripetal/moderate or centrifugal/ideological strategies in order to obtain political victories. We found that the parties sought both political victories and the manifestation of ideological positions in all arenas. These positions characterized the Democratic Party as center-liberal and the Republican Party as center-conservative in the ideological spectrum of the foreign policy. However, in specific political contexts, the parties have made ideological inflections in order to obtain only victories. These inflections can be explained by variations on the perception of external threat, on the evaluation of the presidential administration, on the degree of control of the Executive over the Legislative, on the composition of the Executive's foreign policy Office, and on the ideological alignment of public opinion. In fact, the parties presented different behaviors in each of the arenas. They were most contentious in the electoral arena than in others. This difference suggests that parties have used seemingly sub-optimal strategies. However, we demonstrate that these strategies rationally express the functions that the parties assume in each of the arenas, being an optimized response to the strategic interaction between them and the political context.
Geometridae (Lepidoptera) e Hymenoptera parasitoides em área de Mata Estacional Semidecídua na Estação Ecológica de Jataí, Luiz Antônio - SP
(Universidade Federal de São Carlos, 2017-06-07) Geraldo, Mariana; Penteado-Dias, Angélica Maria; https://lattes.cnpq.br/8637344058859147; Dias Filho, Manoel Martins; https://lattes.cnpq.br/1346547036069954; https://lattes.cnpq.br/8308083022956130
Larvae of Geometridae (Lepidoptera) were obtained with an entomological umbrella, from October 2013 to September 2015, in two areas of semi-deciduous forest (Mata/Cerradão and Mata) at Estação Ecológica de Jataí, Luiz Antônio, São Paulo state. The larvae of Geometridae were kept in the laboratory until the adult or parasitoid emergence. Especimens of the families Braconidae and Ichneumonidae were obtained, from January 2014 to February 2015, with two Malaise traps located in the same local of collection of Geometridae larvae. The material obtained in the Malaise traps was sorted, the individuals of the families Braconidae and Ichneumonidae were identified in subfamily level and the Microgastrinae, Cheloninae and Rogadinae, Campopleginae and Mesochorinae subfamilies were identified at the genus level. A total of 416 larvae of Geometridae weas collected, 190 in the Mata/Cerradão stretch and 226 in the Mata stretch, of which, 52 and 39, respectively, were parasitized. Among the Geometridae, the subfamily Ennominae was represented by individuals of 14 genera (Argyrotome, Glena, Hymenomima, Iridopsis, Ischnopteris, Lomographa, Macaria, Nepheloleuca, Patalene, Phrygionis, Physocleora, Prochoerodes, Rhomboptila and Trotopera), the subfamily Larentiinae by four (Eubaphe, Eupithecia, Euphyia and Pterocypha) and the subfamily Sterrhinae by two (Cyclophora and Idaea). A total of 91 larvae of Geometridae, from 11 genera, were obtained parasitized by 198 parasitoids. The parasitoids obtained belong to the families Braconidae, Ichneumonidae, Eulophidae and Diptera. The Malaise traps provided 2720 individuals of the Ichneumonoidea superfamily, of these 1210 are Braconidae and 1510 are Ichneumonidae, in the Mata/Cerradão stretch, and 702 in the Mata stretch, of which 214 individuals of the Braconidae family and 488 individuals of the Ichneumonidae family. Among the Braconidae, the subfamily Microgastrinae was the most abundant, with 44.5% of individuals in the Mata/Cerradão stretch and 31.8% in the Mata stretch. Eighteen genera of Microgastrinae were recorded (Alphomelon, Apanteles, Choeras, Cotesia, Diolcogaster, Distatrix, Glyptapanteles, Hypomicrogaster, Iconella, Microplitis, Papanteles, Parapanteles, Pholetesor, Prasmodon, Promicrogaster, Protapanteles, Pseudapanteles and Rasivalva), five of Rogadinae (Aleiodes, Choreborogas, Rogas, Stiropius and Yelicones) and four of Cheloninae (Ascogaster, Chelonus, Microchelonus and Phanerotoma). Between the Ichneumonidae collected, 161 individuals were obtained from the subfamily Campopleginae in the Mata/Cerradão stretch and 35 in the Mata stretch. The genera of Campopleginae obtained were Campoletis, Campoplex, Casinaria, Charops, Cryptophion, Cymodusa, Diadegma, Dusona, Hyposoter, Microcharops and Venturia.
