In the Cerrado, veredas are linear physiognomies that occur on hydromorphic soil usually along narrow water courses. They often growth on flat terrain or near headwaters. They are characterised by the abundance of buriti palms (Mauritia flexuosa) that growth over other trees, numerous shrubs and a dense herbaceous stratum. Despite being common landscape elements through the Cerrado's extension, the use of veredas by birds has not been examined in detail. This study aimed to review studies of birds and veredas in the Cerrado. Publications (n = 25) reported the use of veredas by 261 bird species. Only 13 of them had aspects of their biology (reproduction and feeding) studied in detail. Veredas are poorly used by Cerrado's endemic species, but are the major habitat requirement of several species. The richness of bird species found in veredas is increased by their inclusion in the home range of forest, savanna and grassland species. This study also discusses the values of veredas to the regional biodiversity, and the major threats to their conservation inside and outside the system of nature reserves. Suggestions for future research on birds and veredas in Cerrado also are provided.

Insight Into

The article outlines the significance of Prussian military music of the 19th and early 20th centuries in an international context. It focuses on deliveries of musical instruments and sheet music by the Berlin company C. W. Moritz to Central and South America around 1900. The delivery lists of 1897/98 for the Colombian military bands show that they were equipped according to the Prussian model, which goes back to the ideas of Wilhelm Wieprecht. He reformed and standardised the Prussian military music system between the 1830s and 1860s, thus creating the basis for its success. The sheet music enclosed with the musical instruments gives an insight into the popular musical taste of the period around 1900, which was increasingly introduced to Central and South America. Future research will ask what impact such imports of music and musical instruments had on the development of music in Central and South America. (Vorlage)

Abstract The previously Brazilian endemic species, Brachymenium regnellii Hampe, has been found in Suriname. It is a member of sect. Rostrata Ochi, distinguished from all other members of that section in Suriname by its percurrent costae. Brachymenium Schwägr. is characterized by the sporophytic features of: erect to suberect capsules; conic-apiculate to short-beaked opercula; and diplolepideous peristomes with narrow, densely papillose exostome teeth and greatly reduced endostomes. Bryum leptotorquescens Müll. Hal ex Broth., previously known from Mexico to western South America, and tropical Africa is reported from Suriname. It differs from other similar mosses in Suriname by the combination of weakly developed leaf borders; strongly decurrent leaves; and costae in cross section with well-developed stereid bands. Bryum billarderei Schwägr. is the correct spelling of that often mis-spelled name.

History Of

Seed-finches are small-sized Neotropical granivorous birds characterized by extremely strong and thick beaks. Among these birds, the Great-billed Seed-Finch Sporophila maximiliani has been selectively and intensively trapped to the extent that has become one of the most endangered bird species in South America, yet its taxonomy remains complex and controversial. Two subspecies have been recognized: S. m. maximiliani (Cabanis, 1851), mainly from the Cerrado of central South America, and S. m. parkesi Olson (= Oryzoborus m. magnirostris), from northeastern South America. Originally, S. m. parkesi was diagnosed as being larger than the Large-billed Seed-Finch, S. c. crassirostris (Gmelin, 1789), but proper comparisons with S. m. maximiliani, which is larger than S. c. crassirostris, were never performed. Here we provide a review of the taxonomic and nomenclatural history of S. maximiliani, reevaluate the validity and taxonomic status of the subspecies based on morphological characters, and significantly revise its geographic distribution. Analyses based on plumage patterns and a Principal Component Analysis of morphometric characters indicated that S. m. parkesi is most appropriately treated as a synonym of the nominate taxon, which results in a monotypic S. maximiliani comprising two disjunct populations. Further, we conducted systematic searches for S. maximiliani in Brazil, in an attempt to obtain natural history information. After more than 6,000 hours of fieldwork in 45 areas of potential and historical occurrence, S. maximiliani was located only in two sites, in marshy environments called veredas, confirming the critical conservation status of this species, at least in Brazil. We discuss the conservation potential for, and the problems involved with, captive breeding of S. maximiliani for reintroduction into the wild.

Quality Control Data

The impact of urban development and climate change has created the impetus to monitor changes in the environment, particularly, the behaviour, habitat and movement of fauna species. The aim of this chapter is to present the design and development of a sensor network based on Smartphones to automatically collect and analyse acoustic and visual data for environmental monitoring purposes. Due to the communication and sophisticated programming facilities offered by Smartphones, software tools can be developed to allow data to be collected, partially processed and sent to a remote server over the network for storage and further processing. This sensor network which employs a client-server architecture has been deployed in three applications: monitoring a rare bird species near Brisbane Airport, study of koalas behaviour at St Bees Island, and detection of fruit flies. The users of this system include scientists (e.g. ecologists, ornithologists, computer scientists) and community groups participating in data collection or reporting on the environment (e.g. students, bird watchers). The chapter focuses on the following aspects of our research: issues involved in using Smartphones as sensors; the overall framework for data acquisition, data quality control, data management and analysis; current and future applications of the Smartphone-based sensor network, and our future research directions.

Several recent systematic and targeted reviews have highlighted limitations in our understanding of talent in sport. However, a comprehensive profile of where the scientific research has focused would help identify gaps in current knowledge. Our goal in this scoping review was (a) to better understand what others have done in the field of research (e.g., what groups have been examined using what research designs and in what areas), (b) to summarize the constituent areas of research in a meaningful way, (c) to help identify gaps in the research, and (d) to encourage future research to address these gaps. Peer-reviewed articles written in English that met several inclusion criteria were analyzed. A total of 1,899 articles were identified, and the descriptive findings revealed a relatively narrow focus of research on talent in sport. Specifically, the majority of examined articles focused on (a) males only, (b) the sport of soccer, (c) perceptual cognitive variables, (d) developing athletes, (e) adult samples, and (f) cross-sectional designs. For better or worse, the concept of talent remains a central element of how coaches, practitioners, and scientists think about athlete development. Findings from this scoping review highlight the continued need to explore issues related to talent identification, selection, and development in more diverse samples (e.g., female athletes and younger ages) and contexts (e.g., from Africa, Asia, and South America). There is also a clear necessity to focus on under-researched areas using alternative methodologies.

North Coast Of Peru

AbstractThe Moche archaeological culture of the North Coast of Peru has been reified into a political system and claimed as the first state in South America. While some recent scholarship has reduced the size of the proposed state, the idea of Moche as a distinct political, social, or ethnic entity remains. In this article we demonstrate that even by the “classic” neoevolutionary theory of the 1960s—1980s the criteria for Moche statehood were not met. We suggest that neoevolutionary models for one or more Moche states are inadequate for understanding an archaeological culture that endured for more than six centuries, and we offer suggestions for directions for future research.

Wheelchair basketball may be the world’s oldest and most popular team sport for persons with a physical disability. At present, there are at least eight major international tournaments as well as zonal qualifying tournaments for the Paralympic Games and the Men’s and Women’s Gold Cup under the auspices of the International Wheelchair Basketball Federation. There were two purposes of this study. The first was to evaluate the participation motives of Polish wheelchair basketball players and the second was to compare the participation motives of Polish and American wheelchair basketball players. Data for this study were obtained from two sources: men and women who participated on Polish wheelchair basketball teams and data reported in studies by Brasile and Hedrick.1 In general, the results indicate that the incentives for participation in wheelchair basketball across these samples of players are more similar than dissimilar. The groups have similar mean scores and standard deviations for the task-oriented incentives. Future research may address whether American or European wheelchair basketball players have more similar participation motives than players from Africa, Asia, Australia, or South America or that the participants in noncompetitive sports or extreme sports have similar motives.
