Abstract. Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species, but also within species. Mammals are an interesting group for investigating trait-based approaches because they play diverse and important ecological functions (e.g., pollination, seed dispersal, predation, grazing) that are correlated with functional traits. Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from À5.83 to À29.75 decimal degrees of latitude and À34.82 to À56.73 decimal degrees of longitude in the Atlantic forest of South America. We present trait information from 16,840 individuals of 181 species of non-volant mammals (Rodentia, Didelphimorphia, Carnivora, Primates, Cingulata, Artiodactyla, Pilosa, Lagomorpha, Perissodactyla) and from 23,010 individuals of 98 species of volant mammals (Chiroptera). The traits reported include body mass, age, sex, reproductive stage, as well as the geographic coordinates of sampling for all taxa. Moreover, we gathered information on forearm length for bats and body length and tail length for rodents and marsupials. No copyright restrictions are associated with the use of this data set.

The integration of ecology and historical biogeography is fostering the investigation of diversity patterns. We studied alpha and beta diversity patterns of Brazilian Atlantic Forest harvestman (Arachnida: Opiliones) communities and related them to environmental and historical factors. Our data bank contains 508 species from 63 sites, encompassing almost the entire latitudinal range of Atlantic Forest. Alpha diversity was higher in coastal sites in the south and southeast regions and decreased in sites inland, as well as in sites in the coastal northeast region, especially in northern Bahia state. Alpha diversity was positively influenced by precipitation and altitudinal range, but the low number of species in northeastern coastal sites seems to be more related to the historical distribution of Neotropical harvestman lineages than to recent environmental factors. Geographic distance was the most influential factor for beta diversity. Compositional changes were also remarkably congruent with areas of endemism delimited for Atlantic Forest harvestmen. The percentage of protected areas for each area of endemism was very unbalanced, and Espírito Santo and Pernambuco states were the least protected areas. The turnover process observed in the compositional changes indicates that conservation strategies should include as many reserves as possible because every community presents a unique set of species.
AGRADECIMENTOS À Renata, pela verdadeira orientação ao longo de tantos anos, pelos inúmeros ensinamentos, sobre ciência e sobre a vida, profissional e pessoal. Obrigada pela oportunidade de trabalhar junto a você! Ao Thomas, por ter sido tão atencioso e presente durante a co-orientação, sempre me questionando e fazendo pensar a todo instante sobre o mestrado. Você foi fundamental para a conclusão dessa dissertação! À Camilinha, amiga marsupial, que me deu muito apoio e energia principalmente no final da dissertação, além de me ensinar a gostar de samba! Àqueles que nos auxiliaram em campo, enfrentando ataques de marimbondo, mordidas de rato, carro esmagado por ônibus, casa pegando fogo, 10 ratos por balde sem lanterna, dias felizes de sol e de chuva torrencial, e com quem pude aprender muito. Em especial ao Mortão, Natali
