DEVELOPMENT OF A SCADA SYSTEM FOR ACCESS, PROCESSING AND SUPERVISION OF DATA COMING FROM A WIRELESS SENSORS NETWORK IN AGRO-ENVIRONMENTAL APPLICATIONS
Wireless sensors networks appeared in the 1970âs for military and
industrial use. They have since undergone a major evolution, particularly since the 90âs,
thanks to the improvements in wireless communications. These changes have allowed
them to participate in a wide variety of applications in different sectors such as
agriculture and environment. This paper shows the development of a SCADA application
programmed with LabVIEWÂź 8.6 (National Instruments), which allows management of
data received by wireless sensors networks through a friendly interface for users. For the
application shown in this paper we have worked with a MEP 510 sensors network
(Crossbow). The functionalities implemented are the following: Network configuration;
Data storage into database; Statistical processing of historical data with polynomial
adjustment and spline interpolation; Visualization by data graphics in real time and
historical data; Visualization of 2D intensity diagrams from the spatial distribution of
sensors; and Creation of a users registry system that allows, depending on the category
assigned, receiving or not access privileges in the application. As a complement we have
developed the possibility of remote access. Sensors network implemented and the
applications developed have been checked by operational tests for each functionality, as
well as sensors joining and leaving the network situations, range of variables and working
modes. The results obtained show the robustness of the SCADA application and the
limitations of wireless sensors networks operating on field conditions

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans â anteaters, sloths, and armadillos â 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
