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. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data.

ResumoO Procyon cancrivorus é um carnívoro silvestre amplamente distribuído e relativamente comum, mas ainda é pouco estudado, existindo poucos trabalhos relatando sobre a biologia dessa espécie. Este trabalho tem como objetivo, caracterizar morfologicamente a glândula pineal de Procyon cancrivorus, através de estudos macro, microscópicos, radiográficos e compará-los com outros animais já estudados. Foram utilizados quatro animais adultos de ambos os sexos, provenientes do Criatório Científico CECRIMPAS, IBAMA (Processo nº 02027.003731/04-76). Macroscopicamente, a glândula pineal de Procyon cancrivorus foi localizada entre os lobos occipitais dos hemisférios cerebrais e cranialmente ao vermis cerebelar, posicionava-se rostralmente aos colículos rostrais e caudal à comissura das habênulas. Microscopicamente, a glândula é revestida externamente por uma cápsula derivado da meninge pia-máter. Foi notada a presença de três tipos de células no parênquima glandular: pinealócitos, células gliais e mastócitos. Não foram encontradas concreções calcáreas na glândula pineal nos estudos radiográficos e microscópicos. Unitermos: glândula pineal, morfologia, Procyon cancrivorus, radiografia AbstractMorphological study of the pineal gland of (crab eater raccoon) Procyon cancrivorus (Cuvier, 1798). The Procyon cancrivorus is a wild carnivore that is widely distributed and relatively common, but it remains little studied, and few works report on the biology of this species. The aim of this work was to characterize morphologically the pineal gland of Procyon cancrivorus through macro, microscopic and radiographic studies, and to compare them with those from other animals. In this work, four adult animals of both sexes were used, originating from the Scientific Herd of CECRIMPAS IBAMA (Process nº 02027.003731/04-76). Macroscopically, the pineal gland of Procyon cancrivorus was located between the occipital lobes of the cerebral hemispheres, cranially to the vermis cerebelar. It was positioned rostrally to the rostral colliculus and caudally to the habenular comissure. Microscopically, the gland was covered externally by a capsule deriving from the meningeal pia mater.
