LEVANTAMENTO DE FAUNA ENTOMONECRÓFAGA DE IMPORTÂNCIA FORENSE ATRAÍDA POR ISCAS COM CARNE SUÍNA (SUS SCROFA L.) NO DISTRITO DE ROSANA-SP
Studies with necrophagous insects essentially helps in the determination of postmortem interval (PMI) of an organism and provides necessary information for criminal investigations in the forensic area. The necrophagous insects with greater incidence in forensic studies belongs to Calliphoridae, Sarcophagidae, Muscidae (Diptera) and Dermestidae (Coleoptera) families. The research was realized near the district of Rosana - SP, in a region known as Pontal do Paranapanema. Traps made with PET bottles with ground pork inside (Sus scrofa L.) were used in an agricultural area surrounding the local diversity. The traps were exposed for 17 days and new traps were added after 9 days of exposure. Were collected 15.715 insects directly from putrefaction gorund pork. The results of this study demonstrate a great diversity of Diptera, with nine families, and six families of coleoptera with forensic interest. The most abundant families were, Calliphoridae, Sarcophagidae and Muscidae, Dermestidae and Histeridae in their respective orders.Estudos com insetos necrófagos auxilia fundamentalmente na determinação do Intervalo pós morte (IPM) de um organismo e fornece informações necessárias às investigações criminais na área forense.

Improvement and Selection of Honeybees Assisted by Molecular Markers
Royal jelly is an important apiarian product for honeybees and has been used as an important ingredient to human health and healthy life style. Because of its wide use, there is great demand in their production. As royal jelly is a secretion of the cephalic glands of bees and it is produced at a certain age of the workers, it is necessary to perform the selection of producing queens to increase the amount produced. The employment of molecular markers is a tool that can be used to identify the genotypes of the best producers. Among the molecular markers, one of them called MRJP3 (Major Royal Jelly Protein 3) has been used in the Program of Improvement of Apis mellifera Royal Jelly Producing (PIAMRJP), State University of Maringá, Brazil. This molecular marker has been efficient in genotyping queens’ royal jelly producers. Combined with classical breeding studies, the selection of queens assisted by MRJP3 marker has allowed to keep the selected genotypes for royal jelly production since 2006 (10 years). In this chapter, we present the main aspects of royal jelly, the hypopharyngeal glands, the major proteins of royal jelly and how it can be used as molecular markers
AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forest
The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer-reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non-invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from different Amazon regions to compile the most extensive data set of inventories of mammal, bird, and reptile species ever assembled for the area. The complete data set comprises 154,123 records of 317 species (185 birds, 119 mammals, and 13 reptiles) gathered from surveys from the Amazonian portion of eight countries (Brazil, Bolivia, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela). The most frequently recorded species per taxa were: mammals: Cuniculus paca (11,907 records); birds: Pauxi tuberosa (3713 records); and reptiles: Tupinambis teguixin (716 records). The information detailed in this data paper opens up opportunities for new ecological studies at different spatial and temporal scales, allowing for a more accurate evaluation of the effects of habitat loss, fragmentation, climate change, and other human-mediated defaunation processes in one of the most important and threatened tropical environments in the world.

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used.
