Escarabeíneos copro-necrófagos (Coleoptera, Scarabaeidae, Scarabaeinae) de fragmentos de Mata Atlantica em Silveira Martins, Rio Grande do Sul, Brasil
Silva, Pedro G. da;Di Mare, Rocco A.;
Iheringia. Série Zoologia , 2012, DOI: 10.1590/S0073-47212012000200012
Abstract: the fauna of scarabaeinae (coleoptera: scarabaeidae) was sampled using pitfall traps baited with human excrement and rotten fish in forest fragments in silveira martins, rio grande do sul, brazil, from november 2010 to january 2011. a total of 1,611 individuals were sampled, belonging to six tribes, 11 genera and 28 species. the most abundant species were canthon latipes blanchard, 1845 (49.9%), c. chalybaeus blanchard, 1845 (13.9%), deltochilum sculpturatum felsche, 1907 (4.9%), and eurysternus caribaeus (herbst, 1789) (4.3%), which accounted for 73% of the total individuals captured. traps baited with human excrement captured a higher number of species than those baited with rotten fish. there was no statistically significant difference between the kinds of baits used in relation to the abundance of scarabaeinae. most of scarabaeinae species was represented by generalist feeding habits and tunneler behavior. the community sampled follows the general patterns of trophic and behavioral structure of scarabaeinae found throughout the neotropical region.

Family Farming, Land Use and Sustainability in the Amazon: Focusing on the Educational Dimension  [PDF]

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.91009
Abstract: The struggles?for land possession and deforestation were some results of the recent occupation process in the Amazon. Family farming was the target of land policies in the region, with recurring failures. Issues related to land governance and pro-poor policies have returned to the discussions, especially by the food production. This study aims to evaluate the relationship between the educational level, land access and sustainable land use among farmers in Acre State, Brazil, in the periods 1996/1997 and 2006/2007. Based on a sample, the methodology worked with variables related to the educational level, the access and the use of land, economic results and solid garbage. The results show that the higher educational level is directly related to the land access security and inversely proportional to sustainability in the land use type. Furthermore, production difficulties are leading to greater market dependence and, consequently, to increased generation of solid garbage, whose disposal may be better directed by improving the farmers’ education.
Emergent matter from 3d generalised group field theories
Alessandro Di Mare,Daniele Oriti
Physics , 2010, DOI: 10.1088/0264-9381/27/14/145006
Abstract: We identify classical solutions of a generalised group field theory model in 3 dimensions, and study the corresponding perturbations, deriving their effective dynamics. We discuss their interpretation as emergent matter fields. This allows us, on the one hand to test the proposed mechanism for emergence of matter as a phase of group field theory, and on the other hand to expose some limitations of the generalised group field theory formalism.
Opinion formation models based on game theory
Alessandro Di Mare,Vito Latora
Physics , 2006, DOI: 10.1142/S012918310701139X
Abstract: A way to simulate the basic interactions between two individuals with different opinions, in the context of strategic game theory, is proposed. Various games are considered, which produce different kinds of opinion formation dynamics. First, by assuming that all individuals (players) are equals, we obtain the bounded confidence model of continuous opinion dynamics proposed by Deffuant et al. In such a model a tolerance threshold is defined, such that individuals with difference in opinion larger than the threshold can not interact. Then, we consider that the individuals have different inclinations to change opinion and different abilities in convincing the others. In this way, we obtain the so-called ``Stubborn individuals and Orators'' (SO) model, a generalization of the Deffuant et al. model, in which the threshold tolerance is different for every couple of individuals. We explore, by numerical simulations, the dynamics of the SO model, and we propose further generalizations that can be implemented.

Abstract: the research has as objective to compare the esteemed diversity for seven of santa maria's counties, rs, brazil, with different urbane levels, based on the study of abundance, similarity and steadiness among 15 papilionidae species, from september 1994 to march 1995 and november 1995 to february 1996. captures were performed in intervals of thirty days, using entomological net, during intervals of 4 hours average. the butterflies were transported in glassine envelopes, individualized, properly labeled to the laboratory at ufsm biology department. the results suggest that the canopy carries out an important function in the distribution and abundance of those butterflies. the mechanisms that act in wider geographical scales can be different from those that act in smaller scales. coppices and urban landscapes can represent locals, where butterflies can use these complex environments exhibiting a reaction norm that minimizes competition and natural enemies' actions use these complex environments exhibiting a reaction norm that minimizes competition and natural enemies' actions.
Morfometria de Papilioninae (Lepidoptera, Papilionidae) ocorrentes em quatro localidades do Rio Grande do Sul, Brasil. III. Análise da forma das asas através de marcos anat?micos

Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000400019
Abstract: this study investigated variation in the forewing morphology of 11 butterfly species (papilioninae), sampled in four communities of the rio grande do sul state. the analyses were performed using descriptors of shape derived from anatomical landmarks, wing areas, and area, length and width of the discal cell. differences in the consensus configuration for wing shape between male and female wings were not significant, showing a high correlation degree. the wing shape did not differ among the four communities investigated. the observed differences in wing shape of the species studied here should be better explained by independent changes associated with different areas of the wing, mainly with the discal cell.

Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000400018
Abstract: this study investigated morphometric parameters associated to flight in papilioninae. comparisons were accomplished with body parts, wing form and dynamics of flight of 10 species collected at four different places. was analyzed the total mass of the body, thoracic mass, length and width and area of fore and hind wings, wing loading and aspect ratio and flight speed prevision. the analyses showed significative differences among species, sexes and communities investigated. the correlations between the length and width of fore wings were positive and significant for both sexes. the values obtained for wing loading, aspect ratio, and estimated flight speed, among sexes and species, were similar to those measured in the field or insectary.
