No. of bitstreams: 1 JenifferCM_DISSERT.pdf: 926553 bytes, checksum: 802fba8946218d778ebe9345c0c66294 (MD5) Previous issue date: 2012-03-27 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / In order to characterize the seasonal and daily rhythm of Dinoponera quadriceps foraging activity in natural environment, four colonies of D. quadriceps were observed in an area of secondary Atlantic forest in northeastern Brazil. Data collection was performed during 72 hours every three months during an annual cycle. Colonies of D. quadriceps exhibited seasonal variation in foraging activity, peaking in the early dry season, followed by a sudden decline at the end of this season and increasing again at the late rainy season. The seasonal rhythm of foraging was positively related to the duration of the daylight and luminosity, and negatively to the time of sunrise and rainfall. Regarding the daily rhythm, foraging activity was predominantly diurnal independent of season. At the early dry season, the colonies had two activity peaks, one in the morning and another in the afternoon, with a decrease in foraging at midday, while in the rest of the year foraging activity was distributed more evenly throughout the daylight. The daily rhythm of foraging activity had a stronger and positive relation with light intensity. The second most important factor determining the daily rhythm of foraging was temperature that was also positively related for most of the year. Relative humidity showed a weak and negative relation with the daily rhythm of foraging in just one month of observation / A fim de caracterizar o ritmo sazonal e di?rio da atividade de forrageio de Dinoponera quadriceps em ambiente natural, foram observadas quatro col?nias de D. quadriceps em ?rea de mata atl?ntica secund?ria no nordeste do Brasil. A coleta de dados foi realizada durante 72 horas ininterruptas a cada tr?s meses, durante um ciclo anual. As col?nias de D. quadriceps exibiram varia??o sazonal da atividade de forrageio, com pico no in?cio da esta??o seca, seguido por uma queda brusca no final dessa esta??o e tendendo a aumentar novamente no final da esta??o chuvosa. O ritmo sazonal de forrageio foi relacionado positivamente ? dura??o da fase clara e ? luminosidade, e negativamente ao hor?rio de nascer do sol e ? pluviosidade. Em rela??o ao ritmo di?rio, a atividade de forrageio foi predominantemente diurna independente da esta??o do ano. No in?cio da esta??o seca, as col?nias tiveram dois picos de atividade, um pela manh? e outro ? tarde, com diminui??o do forrageio no meio do dia, enquanto que no resto do ano a atividade de forrageio foi distribu?da de forma mais uniforme ao longo da fase clara. O ritmo di?rio da atividade de forrageio foi relacionado mais fortemente e de forma positiva ? luminosidade. O segundo fator mais importante na determina??o do ritmo di?rio de forrageio foi a temperatura, tamb?m relacionada positivamente durante a maior parte do ano. Por ?ltimo, a umidade apresentou uma rela??o fraca e negativa com o ritmo di?rio de forrageio em apenas um m?s de observa??o

Nesta pesquisa, examinei decis?es comportamentais no contexto de forrageamento da formiga Dinoponera quadriceps com rela??o ? orienta??o, avalia??o do alimento e din?mica do forrageio ao n?vel do indiv?duo. O estudo foi realizado no Laborat?rio de Biologia Comportamental na UFRN e em uma ?rea de Mata Atl?ntica secund?ria na FLONA-ICMBio de N?sia Floresta/RN. Em todas as observa??es e experimentos as formigas foram marcadas individualmente com uma etiqueta, com c?digo alfanum?rico, colada no t?rax. Na primeira parte do estudo analisei as pistas de orienta??o utilizadas por D. quadriceps. Em um labirinto de 17 compartimentos testei cada oper?ria forrageadora por 10 min em tr?s sess?es para seis tratamentos diferentes. Os tratamentos consistiam da presen?a ou aus?ncia de odor e de marcas visuais superiores ou frontais. As oper?rias demonstraram que a presen?a de odor ? indispens?vel e que marcas visuais frontais s?o mais eficazes do que as visuais superiores. Na segunda parte, investiguei a discrimina??o do alimento, considerando os par?metros tamanho, peso e volume. Em um experimento de ?cafeteria?, disponibilizei em uma placa de Petri, dentro de uma arena experimental de 1m?, peda?os de alimento (mortadela) de forma cil?ndrica. Inicialmente, os peda?os eram de quatro tamanhos diferentes; numa segunda etapa, os peda?os eram do mesmo tamanho, mas com peso diferente; na ?ltima etapa, os peda?os tinham mesmo peso, mas volume diferente. O resultado mostrou o efeito dos par?metros tamanho e peso para a escolha do alimento. Na terceira parte do estudo, avaliei a influ?ncia da atividade das forrageadoras ativas nas inativas. As col?nias foram observadas em ambiente natural. As observa??es aconteciam em tr?s dias consecutivos por 10 vezes, total de 30 dias para cada col?nia, 12 horas/dia. No primeiro dia, eu observava a sa?da e entrada das oper?rias; no segundo dia, foram retiradas as oper?rias mais ativas e devolvidas ao final das observa??es; no terceiro dia, as observa??es eram similares ao primeiro dia. Como resultado, as oper?rias de D. quadriceps realizam autoestimula??o e n?o facilita??o social e a col?nia compensa a falta das oper?rias mais ativas. Com base no exposto, eu concluo que as oper?rias de D. quadriceps usam pistas de orienta??o qu?mica e visual frontal e superior nos seus deslocamentos. Elas discriminam o alimento escolhido por tamanho e peso. A regula??o da din?mica de atividade das forrageadoras ? por autoestimula??o, uma oper?ria ativa n?o influencia a atividade de uma forrageadora inativa, o sucesso da busca pr?via ? um est?mulo para a pr?pria oper?ria bem sucedida continuar a atividade de forrageio / The behavioral decisions of animals do not occur randomly, because behaviors are adjusted to ensure the survival and reproduction of the animal. In this research, I examined behavioral decisions in the foraging context of the ant Dinoponera quadriceps with regard to orientation, food avaliation and foraging dynamic to individual level. The study was conducted at the Laboratory of Behavioral Biology at UFRN and in an area of secondary Atlantic Forest in FLONA-ICMBio N?sia Floresta/RN. In all observations and experiments, ants were marked individually with an alphanumeric code label fixed on the thorax. In the first part of the study, I analyzed the orientation cues used by D. quadriceps. The tests were performed in a maze of 17 compartments. Each forager was tested for 10 min in three sessions for six different treatments. The treatments consisted of the presence or absence of odor and superior or frontal visual cues. The workers demonstrated that the presence of odor is indispensable and front visual cues are more effective than superior visual cues. In the second part, I investigated the discrimination of food, considering the parameters, size, weight and volume. In a 'cafeteria' experiment, I offered cylindrical pieces of food (mortadella) in a Petri dish, within an experimental arena 1m?. Initially, the pieces were of four different sizes; in a second step, the pieces were of the same size but with different weight; in the last step, the pieces had the same weight but different volumes. The results showed the effect of the size and weight parameters for food choice. In the third part of the study, I evaluated the influence of the activity of active foragers on inactive ones. In this part, the colonies were observed in a natural environment. The observations took place on three consecutive days in 10 episodes, total of 30 days for each colony, 12 hours/day. On the first day, I registered the output and input of workers; on the second day, the most active ants on the first day were taken and given back at the end of the observations; on the third day, the observations were similar to the first day. As a result, the workers of D. quadriceps show autostimulation and they do not show social facilitation and the colony compensates the absence of the most active workers. Based on the stated, I conclude that workers of D. quadriceps use chemical, frontal and superior visual orientation cues during their displacements. They discriminate the chosen food by size and weight. The regulation of activity dynamics of foragers is by autostimulation, an active worker does not influence the activity of an inactive worker, the successful search previous is the stimulus to the successful worker itself to continue foraging activity.

Tamb?m investigamos, medindo o tempo de perman?ncia em cada ?rea, a influ?ncia do aprendizado no desempenho das oper?rias ao longo de sucessivas viagens. Foram simulados quatro cen?rios. Cada oper?ria realizou 10 viagens em cada cen?rio. Cen?rio 1: oper?rias sempre encontravam alimento de alta qualidade; Cen?rio 2: oper?rias encontravam alimento de alta qualidade em somente 50% das viagens; Cen?rio 3: oper?rias encontravam alimento de alta e baixa qualidade com probabilidades de ocorr?ncia de 0,5 para cada tamanho de alimento. Cen?rio 4: oper?rias tinham tr?s possibilidades, encontrar alimento de alta qualidade (33%), encontrar alimento de baixa qualidade (33%) e n?o encontrar alimento. Em todos os cen?rios, havia duas rotas poss?veis de explora??o, uma com 300 cm e outra com 600 cm de comprimento. A pesquisa mostrou que oper?rias da esp?cie D. quadr?ceps tendem a retornar ao mesmo local onde o alimento foi encontrado na viagem anterior, n?o importando a dist?ncia, tamanho do alimento ou taxa de recompensa. Nos casos de viagens sem captura, oper?rias eram mais propensas a trocar de ?rea em busca de alimento. No entanto, no cen?rio 4 essa decis?o de ?troca? foi menos evidente, possivelmente pela maior din?mica do cen?rio. Resultados tamb?m indicaram um processo de aprendizado das rotas de explora??o assim como das condi??es das ?reas de explora??o. Com a repeti??o das viagens, forrageadoras reduziram o tempo de busca nas ?reas nas viagens que n?o capturavam alimento e rapidamente trocavam de ?rea. / When searching for food, animals often make decisions of where to go, how long to stay in a foraging area and whether or not to return to the last visited spot. These decisions can be enhanced by cognitive traits and adjusted based on previous experience. In social insects such as ants, foraging efficiency have an impact on both individual and colony level. The present study investigated, in the laboratory, the effect of distance from food, capture success and food size, and reward rate on decisions of where to forage in Dinoponera quadriceps, a ponerine ant that forage solitarily and individually make their foraging decisions. We also investigated the influence of learning on the performance of workers over successive trips searching for food by measuring the patch residence time in each foraging trip. Four scenarios were created differing in food reward rates, food size offered and distances colony-food site. Our work has shown that as a rule-of-thumb, workers of D. quadriceps return to the place where a prey item was found on the previous trip, regardless of distance, food size and reward rate. When ants did not capture preys, they were more likely to change path to search for food. However, in one of the scenarios, this decision to switch paths when unsuccessful was less evident, possibly due to the greater variation of possible outcomes ants could experience in this scenario and cognitive constraints of D. quadriceps to predict variations of food distribution. Our results also indicated a learning process of routes of exploration as well as the food site conditions for exploration. After repeated trips, foragers reduced the patch residence time in areas that they did not capture food and quickly changed of foraging area, increasing their foraging efficiency.

Foram observadas duas col?nias numa ?rea de mata atl?ntica secund?ria na FLONA-ICMBio de N?sia Floresta, Estado do Rio Grande do Norte, pelo menos uma vez por semana. Inicialmente, observamos as oper?rias, desde a sa?da do ninho at? o retorno, sem qualquer tipo de manipula??o, numa segunda fase, introduzimos uma placa de acr?lico (100 x 30 x 0,8 cm) diante da entrada observada. Todo o registro comportamental foi feito com a t?cnica do focal time sampling e todas as ocorr?ncias, como complementar; os focais eram de 15 min, com registro a cada minuto, e intervalo de 5 min entre eles. As oper?rias gastaram a maior parte do tempo fora do ninho no comportamento de forrageio. O tempo fora do ninho e a dist?ncia percorrido mostra uma rela??o positiva. Estas vari?veis influenciaram na propor??o do alimento, que requereu mais tempo e dist?ncia na busca. A propor??o tamb?m interferiu no tempo que a oper?ria ficava no ninho antes de uma nova viagem, maior propor??o menor tempo no ninho. Durante toda a pesquisa, as oper?rias individuais demonstraram fidelidade ? rota e a setores na ?rea de uso, mesmo na presen?a da placa, na qual elas desviavam e continuavam seu curso. As caracter?sticas no forrageio quanto ao tempo, dist?ncia, rota fixa e flexibilidade para desviar de obst?culos, apresentadas pelas oper?rias indicam que as decis?es ocorrem em n?vel individual e ? eficiente em rela??o ao balan?o custo-benef?cio. A estrat?gia adotada se encaixa na teoria do ponto central e no teorema do valor marginal, e demonstra ser flex?vel ? presen?a de informa??es novas, o que indica que as oper?rias s?o capazes de aprender novas pistas do ambiente para orient?-las / In this study, we investigated the role of routes and information attainment for the queenless ant species Dinoponera quadriceps foraging efficiency. Two queenless ant colonies were observed in an area of Atlantic secondary Forest at the FLONA-ICMBio of Nisia Floresta, in the state of Rio Grande do Norte, northeastern Brazil, at least once a week. In the first stage of the study, we observed the workers, from leaving until returning to the colony. In the second stage, we introduced a acrylic plate (100 x 30 x 0,8 cm) on a selected entrance of the nest early in the morning before the ants left the nest. All behavioral recordings were done through focal time and all occurence samplings. The recording windows were of 15 minutes with 1 minute interval, and 5 minute intervals between each observation window. Foraging was the main activity when the workers were outside the nest. There was a positive correlation between time outside the nest and distance travelled by the ants. These variables influenced the proportion of resource that was taken to the nest, that is, the bigger its proportion, the longer the time outside and distance travelled during the search. That proportion also influenced the time the worker remained in the nest before a new trip, the bigger the proportion of the item, the shorter was the time in the nest. During all the study, workers showed fidelity to the route and to the sectors in the home range, even when the screen was in the ant?s way, once they deviated and kept the route. The features of foraging concerning time, distance, route and flexibility to go astray by the workers indicate that decisions are made by each individual and are optimal in terms of a cost-benefit relation. The strategy chosen by queenless ants fits the central place foraging and marginal value theorem theories and demonstrate its flexibility to new informations. This indicates that the workers can learn new environmental landmarks to guide their routes

As taxas de intera??es na col?nia s?o reguladas pela densidade de indiv?duos que ela cont?m e atrav?s das quais pode haver rapidez na transfer?ncia de informa??o, provocando mudan?as na din?mica de rede social. A fim de analisar o fluxo de informa??o em oper?rias de Dinoponera quadriceps investigamos duas col?nias com base na quantidade de oper?rias e larvas no ninho, n?mero de intera??es individuais, n?mero de sa?das, ?for?a? e ?alcance? de cada intera??o, al?m do fluxo de informa??o em diferentes hor?rios. O estudo foi realizado no Laborat?rio de Biologia Comportamental da UFRN. Foram observadas duas col?nias com diferentes densidades de oper?rias por 16h/col?nia, totalizando 8h/dia atrav?s de grava??o com c?mera digital. As col?nias de D. quadriceps n?o apresentaram correla??o entre o n?mero total de intera??es com o n?mero total de oper?rias e nem com as sa?das do ninho. As taxas de intera??es per capita apresentaram padr?o semelhante para as duas col?nias, sendo maiores no hor?rio com disponibilidade de alimento. A col?nia com menor densidade de oper?rias apresentou mais intera??es por individuo, principalmente no dia e hor?rio com alimento, e estas intera??es obtiveram maior ?for?a? e ?alcance?. A din?mica de redes sociais tamb?m apresentou padr?o semelhante entre as col?nias, apresentando maiores fluxos de informa??o no hor?rio com alimento. Com base no exposto conclu?mos que as oper?rias de D. quadriceps regulam a atividade de forrageamento atrav?s de autoestimula??o, como tamb?m suas taxas de contato, aumentando o n?mero de intera??es em dia e hor?rio com alimento na col?nia, modificando o fluxo de informa??o e aumentando a dissemina??o da informa??o. / Social interactions between workers in a colony do not happen randomly, since workers decide how often they will interact and who they will interact with. Interactions rate in the colony are regulated by the density of individuals it contains and through which can quickly transfer information in the colony, causing changes in network dynamics. In order to analyze the flow of information among workers of Dinoponera quadriceps we investigated two colonies based on the number of workers and larvae in the nest, number of individual interactions, number of outputs, 'strength' and 'reach of each interaction, and also the information flow at different times. The study was conducted in the Behavioral Biology Laboratory at UFRN. Two colonies with different densities of workers were observed for 16h/colony, totaling 8 hours/day by recording using a digital camera. Colonies of D. quadriceps showed no correlation between the total number of interactions with the total number of workers nor to the number of nest exits. The per capita rates of interactions showed a similar pattern in both colonies, being higher during the food availability periods. The colony with lower density of workers had more interactions per individual, especially on the day and period with food, and these interactions got stronger and greater range. The dynamics of social networks also showed a similar pattern among colonies, with greater flow of information during the feeding time. Based on these results we conclude that workers of D. quadriceps regulate foraging activity through self-stimulation, as well as with their contact rates by increasing the number of interactions when food was offered to the colony, changing the flow of information and increasing dissemination of information.

However some species respond less aggressively to intrusion by neighbors than non-neighbors in its territory to minimize the costs of continuous fight. This difference in aggression is called Dear Enemy Effect described in various vertebrates and invertebrates. To investigate if this phenomenon occurs in Dinoponera quadriceps (Hymenopetra, Formicidae) three colonies, two neighbors and one non-neighbor, were captured in its natural environment then transfered to the laboratory where we did experimental confrontation intra and inter colonies involving one pair of workers. We compared the behavioral frequency exhibited by each worker, the intensity and duration of the confrontation between a neighbor and a non-neighbor referring the place where they were collected. Our results revealed that Dear Enemy Effect does not apply to D. quadriceps due aggressive response is more intense and longest toward neighbor than non-neighbor, probably due intra specific competition, ecological factors and characteristic of the species / O acesso a fonte de alimentos, territ?rio ou parceiros reprodutivos pode gerar conflitos de interesses entre indiv?duos em v?rias esp?cies de animais.

Displays of C. jacchus self-recognition using a mirror, were appraised with two protocols: no mark and with mark. D.quadriceps navigational capability displays during foraging trips to food resource, were appraised considering three different tests categories: (1) free access, (2) blocked by opaque object; and 3) blocked by clear object. Our results show self-perception in both studied species. With marmosets displaying contingency check behaviour to the specular image, self-observation, environmental exploration using the mirror as a tool and little, but significant mark reactions. Tocandiras were able to perceive its own location and to calculate short return paths to the colony after obtaining the food resource in all three types of tests. Here we provide further evidence of conscious states for species other than vertebrates.
