NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset
Retomando a Interrupção... Getting Back to Interruption...
Este trabalho é uma continuação de outros estudos sobre interrupção que vêm sendo desenvolvidos desde 1995 pelo grupo "Organização textual interativa" no âmbito do Projeto da Gramática do Português Falado. Nosso objetivo é explicitar o estatuto da interrupção: trata-se de um mecanismo de construção do texto falado ou, apenas, de um índice de ocorrência de alguns desses mecanismos (correção, paráfrase, repetição, parênteses)? Para responder a essa questão, analisamos seis inquéritos de natureza diferente (elocuções formais - EFs - , entrevistas - DIDs - e diálogos entre dois informantes - D2s), extraídos do Projeto NURC/SP, NURC/RJ e NURC/Recife. Do ponto de vista teórico, recorremos às pesquisas desenvolvidas pelo grupo acima mencionado, cujos artigos foram publicados na coleção: Gramática do Português Falado ( volumes IV, V e VI ) .<br>This work follows other studies on interruption that we have been developping since 1995 in a group engaged in the interactive textual organization within the Grammatical Project of the Spoken Portuguese. Our aim is to uncover the status of interruption: is it a mecanism of construction of the spoken text or only of a token of the occurrence of some of these mecanisms (correction, paraphrase, repetition, parentheses)? To answer this question, we analysed six inquiries of different nature (formal elocutions - Efs; interviews - DIDs - and dialogues between two informants - D2s) extracted from the NURC/SP, NURC/RJ and NURC/Recife Project. As to the theoretical point of view, we turned our attention to assumptions which supported the arguments put forward by the researchers belonging to the above mentioned group, whose articles were published in Grammatical Project of Spoken Portuguese (IV, V, VI
