Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer‐reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non‐vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non‐vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra‐ and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.

This study firstly reviewed the interspecific interaction records between birds and epiphyte plants in Brazil. Forty two documents, including articles, scientific notes, books and thesis, and 35 personal records and from collaborators were argued, totaling 112 species of birds that interacted with 97 species of epiphyte plants. Two articles treated the theme specifically and another 40 treated related subjects, such as: pollination of epiphytes, ecology and feeding behavior of birds. Studies were concentrated mainly in Atlantic Forest, in the southeastern Brazilian region. The epiphyte species more visited by birds was Aechmea nudicaulis (Bromeliaceae). The main visitor of epiphytes was Ramphodon naevius (Trochilidae). According to the number of authors' citations an index of generality in bird-epiphyte interactions was created. As result the index inferred that the ovenbird Cichlocolaptes leucophrus and the bromeliad Nidularium procerum are less generalist and more specialist species in bird-epiphyte interactions. The totality of the papers showed a considerable number of bird species that use the epiphytes plants and its resources, including nectar, fruits, invertebrates, nest material, nesting place, water and bath. Considering the importance of epiphytes to supply a variety of resources for birds, these results highlighted the necessity of additional and specific studies about the theme in various Brazilian regions and biomes. Keywords: Atlantic Forest, avian community, bird-plant interaction, bromeliads, resources. RESUMO O USO DE PLANTAS EPÍFITAS POR AVES NO BRASIL.O presente estudo trata-se da primeira revisão sobre registros de interações interespecíficas entre aves e plantas epífitas no Brasil. Quarenta e dois documentos, incluindo artigos, notas científicas, livros, teses e 35 registros pessoais e de colaboradores foram levantados, totalizando 112 espécies de aves que interagiram com 97 espécies de plantas epífitas. Dois artigos se referiram sobre o tema especificamente, e outros 40 documentos trataram de assuntos relacionados, tais como polinização de epífitas, ecologia e forrageamento de aves. Os estudos foram realizados principalmente na Mata Atlântica da região sudeste do Brasil. A espécie de epífita mais visitada pelas aves foi Aechmea nudicaulis (Bromeliaceae). A principal espécie de ave visitante de plantas epífitas foi Ramphodon naevius (Trochilidae). Considerando o número de citações, foi criado um índice de generalização para interações entre espécies de aves e epífitas. Este índice inferiu que o furnariídeo Cichlocolaptes leucophrus e a bromélia Nidularium procerum são respectivamente as espécies menos generalistas e mais especialistas em interações interespecíficas aves-epífitas. A totalidade dos estudos mostrou um considerável número de espécies de aves que utilizam as plantas epífitas e seus recursos, incluindo néctar, frutos, invertebrados, material para ninho, local para nidificação, água e banho. Considerando a importância da variedade de recursos oferecidos pelas plantas epífi...
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.

The habits and general behaviour of the chachalacas (Ortalis spp.) in the Neotropics are well known. However, the validity and even the diagnoses of some taxa are poorly studied, and this may jeopardize the conservation of some populations. Within Ortalis guttata two subspecies are currently accepted, the nominate O. g. guttata (Spix) and O. g. subaffinis Todd. A third taxa, O. g. remota Pinto, 1960, was described based on a single specimen from SE Mato Grosso do Sul state, Brazil. Despite appreciable differences between O. g. remota and other members of Ortalis, this taxon was considered as a synonym of O. squamata, a species restricted to the lowlands of Atlantic Forest, east of Serra do Mar. Here we performed coloration and geographical distribution analysis of O. g. remota with additional examination of the holotype and a thorough comparison of skins and photos with other members of Ortalis (O. squamata, O. araucuan, and O. guttata) intending to disentangle the above taxonomic puzzle. Our results showed that a newly recognized population of O. g. remota differs consistently from all other Ortalis taxa currently treated as distinct species in plumage characters and geographic distribution. Therefore, we defend that it should be considered a valid species, Ortalis remota Pinto, 1960. Ortalis remota has a very restricted range on the upper Paraná River and it is threatened by deforestation and construction of dams.
