A delimitação geográfica de um bioma engloba questões que envolvem fatores ambientais, como clima e características da vegetação, além de aspectos políticos. Consequentemente, variações na delimitação de um bioma são recorrentes. A Mata Atlântica é um dos mais importantes hotspots de biodiversidade do mundo e historicamente diversas delimitações territoriais foram propostas para esse bioma. Aqui tivemos como objetivo 1) discutir as quatro principais delimitações e 2) com base nos limites existentes, discutir sua união (Limite Integrativo) e intersecção (Limite Consensual). Os principais limites apresentam áreas consensuais e integrativas de 1,01 e 1,62 milhão km 2 , respectivamente. Cinco regiões de divergência devem ser cuidadosamente avaliadas. Finalmente, sugerimos um debate sobre o uso de limites em estudos ecológicos e sua aplicação em estudos sobre conservação da biodiversidade.

The geographic delimitation of a biome encompasses questions that involve environmental factors such as climate and vegetation characteristics as well as political aspects. Consequently, variation on biome delimitation is recurrent. The Atlantic Forest is one of the most important biodiversity hotspots in the world, and historically several territorial delimitations have been proposed for this biome. Here we aim to 1) discuss the four main delimitations and 2) based on the existing limits, discuss their union (Integrative limit) and intersection (Consensual limit). The main limits present consensual and integrative areas of 1.01 and 1.62 million km 2 , respectively. Five regions of divergence must be carefully evaluated. Finally, we suggest a debate about the use of limits in ecological studies and their application in biodiversity conservation studies.

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 Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae).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.

Despite its wide distribution in South America, ranging from northern Venezuela and the Guianas south to Paraguay and northern Argentina, the vulnerable giant armadillo (Priodontes maximus) occurs at low densities and is little studied due to its elusive habits. In Brazil species' records have been collected from the Pantanal and central Cerrado but little information is known from the eastern border of Mato Grosso do Sul. Here we report 97 records of giant armadillo in this region from areas of private lands using camera-traps and signs of presence in Cerrado and Atlantic Forest biomes.

Palavras-Chave: Reflexão orientada, formação inicial de professores, ensino de Química. AbstractOriented Reflection process (PRO) is an initiative that may promote situations in which pre-service teachers reflect on their development of lesson plans, elaboration and preparation of intervention activities in chemistry teaching. Nowadays, teachers assume a role of facilitator in knowledge construction, and their duty is create investigative activities that provide students to develop skills necessary for understanding the world around them. Thus, this study investigated the evolution and relation among investigative levels, scientific literacy and cognitive levels present in four educational proposals which compose an instructional sequence for specific content, prepared by two pre service chemistry teachers of a public university, during a process of oriented reflection. The results show that the educational proposals evolution in most of analyzed topics, which could be justified by reflections offered to pre service teachers by individual and group meetings.

Abstract:The largest felid in the Americas, the Jaguar (Panthera onca) has had its geographical distribution reduced to approximately half the original range throughout the years, and most of its remaining distribution is in Brazilian territory. Deforestation is considered the main threat to the species, especially in the Atlantic Rainforest, which is currently highly fragmented and modified. This article provides a new record of Jaguar in Paraná state, in an area occupied by a mosaic formed by native vegetation and silviculture, and represents a new recent locality of the species for the biome in which it is classified as Critically Endangered of extinction.
