The connection between legal and illegal firearms markets: how the change in gun control policy in Brazil intensified this link

In recent decades, the global debate on gun control has been prominent, with many countries adopting more restrictive policies. Brazil followed this trend by implementing stringent measures in 2003; however, the presidency of Jair Bolsonaro in 2019 introduced normative changes aimed at facilitating public access to firearms and ammunition. Throughout his term, the legal firearms market doubled, allowing access to weaponry previously restricted to the general public. The analyzed hypothesis suggests that these normative changes, especially those related to the quantity and authorization of acquisition of previously restricted firearms, altered the types of firearms in circulation, strengthening the interaction between legal and illegal markets. Using data from the mandatory firearms re-registration, a total of 962,782 firearms were analyzed. The assessment of the increase in circulation of these firearms in the illegal market was conducted through the analysis of seizures in the states of Rio de Janeiro and São Paulo, revealing a significant growth in seizures of these types of firearms, possibly correlated with the increase in their circulation. Three police investigations were selected to exemplify how the connection between markets intensified, allowing criminals to obtain firearms in the legal market that were previously only accessible through international trafficking or diversion from state agencies

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 Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae).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. We also request that users inform us of how they intend to use the data

Comments on a notorious verdict : the trial of Lula

“Comments on a notorious verdict: The trial of Lula” might be the most important judicial document published in Brazil for decades. The present selection of articles came to exist after a spontaneous movement, and significant enough as well, of Brazilian and foreign lawyers who carefully verified the verdict rendered in the extent of the procedure which was processed at the 13ª Vara Federal de Curitiba, in the case that was known at the media as “the Guarujá triplex”. From the Introduction by Geraldo Prad
