CA002-01 Interações entre fatores biológicos e psicológicos no comportamento e no desenvolvimento Ferrari EAM* O objetivo deste capítulo é descrever e discutir questões relacionadas com a análise do comportamento e do desenvolvimento como produtos da interação entre fatores biológicos e psicológicos. Para isso, uma seção inicial é dedicada à definição de conceitos referentes a classes de comportamento. A análise dos fatores biológicos aborda alguns dos principais conceitos e problemas relacionados com a filogenia e com a abordagem evolutiva. A análise dos fatores psicológicos está centrada na ontogenia, caracterizada pelos processos de aprendizagem e desenvolvimento, com a modificação do comportamento em função de relações de contingência e de contigüidade entre eventos comportamentais e ambientais. São também abordadas questões derivadas da neurociência. Finalmente, discutem-se as relações entre os princípios da filogênese e da ontogênese do comportamento.

CA004-01 Introduction: Development of research in the cerrados Oliveira PS*, Marquis RJ This volume treats the historical origins and physical setting, the role of fire, major biotic taxa, insect-plant interactions, and functional processes at different levels of organization (population and community) and scale (local and landscape). The book is organized in five sections, as follows: Part I provides the historical background and presents the main abiotic properties of the cerrado region. Part II focuses on the plant community and begins with the description of the vegetation physiognomies and the origins of the cerrado biome, followed by the main attributes of the herbaceous layer. Population characteristics of trees in the absence and presence of fire are also treated. Part III gives a general picture of the animal community, focusing on probably the five best-known animal taxa of the cerrados. Part IV covers those species interactions that are currently best-documented in the cerrado: insect-plant systems. Part V closes the book by examining the state of preservation of the cerrado ecosystem, the current threats to its biodiversity, and the appropriate strategies to be adopted based on the identification of priority areas deserving immediate conservation actions.

CA005-01 Ant foraging on plant foliage: contrasting effects on the behavioral ecology of insect herbivores Oliveira PS*, Freitas AVL, Del-Claro K The ecological success of ants is attributed to their eusocial mode of life, local abundance, and diversity of adaptations. Such traits result in a wide variety of feeding habits and foraging strategies, including the use of plant foliage as a foraging substrate. Intense foraging on vegetation appears to have set the scenario for a multitude of interactions with many plant species worldwide, ranging from facultative to obligate ant-plant associations. Incidentally, by frequently foraging on the plant surface ants often affect the life of a particular trophic group -- the herbivores. Most studies on ant-plant interactions, however, have focused on the deterrence by ants toward insect herbivores and its possible influence on plant fitness. Rarely has this interface been studied from the herbivore's standpoint. In this chapter we illustrate how intense ant activity on plant foliage can strongly affect the behavioral ecology of insect herbivores in the cerrado. We first present the factors that likely promote ant foraging on cerrado plants, and then describe two study cases in which the behavior of insect herbivores has been demonstrated to be closely linked with encountering ants on the plant surface In: Oliveira PS, Marquis RJ (eds) The Cerrados of Brazil: Ecology and Natural History of a Neotropical Savanna.

CA006-01 The Cerrados of Brazil: Ecology and Natural History of a Neotropical Savanna Oliveira PS*, Marquis RJ (eds.) This is a book about the Cerrado Biome, a major Brazilian savanna-like ecosystem for which no such summary exists. Biologists outside Brazil know little about the cerrados, despite the fact that the biome covers approximately 22% of the country's surface area, or 2 million km2. Even though much of the attention of conservationists has focused on rain forests, such as the Amazon and Atlantic forests, the cerrados presently are one the most threatened biomes of South America due to the rapid expansion of agriculture. Nearly 50% of the cerrado region is currently under direct human use, and about 35% of its total natural cover has been converted into planted pastures and crops. The average annual rate of land clearing in the cerrados during 1970-1975 was nearly twice the estimated deforestation rate of the Amazon forest during 1978-1988. Overall biodiversity for the Cerrado Biome, including all its physiognomic forms, is estimated at 160,000 species of plants, animals, and fungi. Endemicity of cerrado higher plants has recently been estimated as 4,400 species, representing 1.5% of the world's total vascular plant species. Endemic vertebrates range from 3% (birds) to 28% (amphibians) of the species recorded. Given their geographic extent it is surprising that the cerrados remain largely ignored at the international level. This is perhaps the first volume in English covering a tropical ecosystem in which the vast majority of the contributors are from the region being reported.

CA009-01 Ant effects on seedling recruitment in Guapira opposita (Nyctaginaceae) in a Brazilian rainforest Passos L, Oliveira PS* Fleshy fruits of tropical forests present a plethora of sizes, shapes, colors, and chemical composition of the edible portion. It has recently been suggested that the outcome of the interaction between ants and fruits/seeds in tropical forests can be largely determined by the size and lipid content of the latter. We investigated ant activity at fallen fruits of Guapira opposita, and the ants' influence on seed fate and seedling recruitment in this species. Results showed that protein content is an important factor in the selection of fruits by ponerines. Pulp removal in Guapira increased germination success, and seedlings and juveniles were more abundant in the vicinity of nests of Odontomachus than in random plots without nests. The study illustrates the complex nature of the dispersal ecology of tropical tree species. In: Ganeshaiah KN, Uma Shaanker R, Bawa KS (eds).

CA010-01 Alarm communication in a neotropical harvestman (Arachnida: Opiliones) Oliveira PS*, Machado G, Bonato V We investigated in the field the possible alarm effect of scent secretions in the gregarious harvestman Goniosoma aff. proximum. Results show that the gland secretion works as an alarm pheromone: while 73.3% of the aggregations dispersed after being stimulated with the gland exudate, only 3.3% responded to the water control. Respondent groups are larger than non-respondent ones, and the time of reaction to the secretion was inversely related with group size. This is the first demonstration of a chemically-mediated alarm effect in harvestmen. The alarm response in gregarious harvestmen has possibly evolved as a by-product of a primarily defensive reaction under the context of predator avoidance.
