In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

Feeding is the primary selective pressure in all forms of animals. Nutritional ecological models predict consequences of preferred and non-preferred food consumption on behavioural, physiological and morphological adaptations. At same time, socioecological models infer socio-organizarion patterns based on feeding competition faced by animals. A list of preferred foods, and inferences regarding the intensity of feeding competition and its behavioural consequences are information of much importance for management of populations in fragments. In this work we observed the feeding behavior and spatial positioning of a group of more than 100 blond capuchin monkeys (Sapajus flavius) that inhabit a fragment of Atlantic forest, surrounded by sugarcane plantation. We compared the consumption of different food items with their monthly availability in the area to define the preferred and fallback food items. We recorded the vocalizations of aggression and the inter-individual distance (area of Minimum Convex Polygon/n individuals) to infer the type of food competition experienced by animals. In the year studied the fruit feeding time correlated with top consumed fruit productivity, indicating preference for fruits. Our data indicate that the species Elaeis sp., Cecropia palmata, Inga spp. and Simarouba amara are the preferred food items in the diet. Available all year round and uniformly distributed, sugarcane was a regular item in the diet and its was characterized as a staple fallback food for this group. Although fruits are preferential food items, direct competition rate did not correlate to fruit productivity in the area, maintaining the high rates throughout the year (2.45 events/ hour). The inter-individual distance index positively correlated with rain fall indicating scramble food competition. The number of neighbours of females carrying infants was smaller when fruit productivity is low, indicating that females carrying infants are suffering increased indirect competition. Our data indicates that blond capuchins in this fragment make use of sugar cane as a staple fallback food, which evidence the importance of sugar cane landscape for the survival of this critically endangered capuchin species in fragmented habitats in Northeast Brazil. A preliminary list of preferred and important foods is offered, and can assist in the choice of trees for reforestation, better fragments to be preserved and areas of release and translocation of animals. We did not observe an increase of contest competition while using preferred foods, but when using staple FBF. This may be due the altered environment, which results in high competition food throughout the year. Both the food preference as the social and behavioral consequences of high food competition experienced by animals in this fragment must be accompanied over the years to ensure the survival of this population.
