    Abstract: A agricultura intensiva e em grande escala promove a conversão de habitats naturais e de culturas agrícolas diversificadas em monoculturas, diminuindo tanto a cobertura de vegetação nativa como a heterogeneidade da paisagem, levando à simplificação da paisagem. No entanto, uma importante lacuna de conhecimento sobre os impactos relativos da perda de vegetação nativa e da heterogeneidade da paisagem na biodiversidade ainda persiste. Preencher esta lacuna é urgente para apoiar políticas que conciliem a produção agrícola e a conservação da biodiversidade e para avançar alguns debates científicos, como ‘ land sharing versus land sparing ’ e ‘ habitat loss versus fragmentation ’. Através de um desenho de amostragem hierárquico que maximizou a variação entre a heterogeneidade da paisagem e a cobertura de vegetação nativa, ao mesmo tempo que minimizou a correlação entre essa métricas, registramos a ocorrência de mamíferos de médio e grande porte em áreas de vegetação nativa e matriz agrícola de 55 paisagens em um hotspot global de conservação e importante área de produção de commodities— a savana brasileira, o Cerrado. Comparamos modelos simples, aditivos e interativos para investigar os efeitos da heterogeneidade da paisagem e da cobertura e vegetação nativa na riqueza e composição de mamíferos nativos e invasores. As comunidades de mamíferos nativos e invasores foram afetadas tanto pela cobertura de vegetação nativa como pela heterogeneidade da paisagem, embora os efeitos da primeira tenham sido mais fortes do que os da segunda. Ambos os aspectos tiveram efeitos positivos na riqueza de espécies nativas e negativos na riqueza de espécies invasoras, indicando que a perda da vegetação nativa e a redução da heterogeneidade da paisagem levam à homogeneização biótica. No entanto, embora a heterogeneidade da paisagem tenha beneficiado a maioria das espécies nativas, a direção do seu efeito variou entre as espécies invasoras e dependeu da cobertura de vegetação nativa. Síntese e aplicações. Além de reduzir a perda de habitat, evitar a homogeneização da paisagem é fundamental para conciliar a produção agrícola e a conservação da biodiversidade, apontando para a relevância de políticas que incentivem a diversificação das culturas. Como o aumento da heterogeneidade da paisagem pode, em parte, compensar os efeitos negativos da perda de habitat nativo sobre a biodiversidade nos agroecossistemas, o manejo de áreas agrícolas e as políticas de conservação em agroecossistemas podem ganhar viabilidade ajustando o equilíbrio entre a cobertura de vegetação nativa e a heterogeneidade da paisagem de acordo com o que melhor se adapta às restrições e exigências locais.

    Abstract: 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., S yncerus 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.

    Abstract: 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.

    Determining abundance predictors of the European Hare ( Lepus europaeus ), a global invader in southeastern Brazil
    Oxford University Press (OUP) ; 2024

    Abstract: European Hare (Lepus europaeus), like many invasive species, have declined in much of their native range but flourished in non-native regions (e.g. South America). Previous studies suggested that loss of farmland heterogeneity due to agricultural intensification is the main driver of the species decline in its native range in Europe. Yet, little is known about the role of spatial and temporal heterogeneity and land cover types as predictors of European Hare local abundance in Neotropical agricultural landscapes. We hypothesized that spatial and temporal heterogeneity, rather than land cover types, would be the most influential predictors of hare local abundance in intensively managed Neotropical agricultural landscapes. We sampled 55 sites embedded within agricultural-dominated landscapes from southeastern Brazil with camera traps and transect surveys. Sites were selected along an uncorrelated gradient of native vegetation cover and compositional heterogeneity. We estimated the relative abundance of European hares using an occupancy model that accounts for imperfect detection of species induced primarily by variation in local abundance. We found that land cover diversity, sugarcane, and savanna cover were the best predictors of European Hare relative abundance. Hare relative abundance estimates were low and did not vary dramatically among sites, suggesting that this invader has not yet attained high local density in our study region. European Hare attained the highest relative abundance in agricultural landscapes that locally combine higher compositional heterogeneity, including sugarcane crops, and little to no native savanna. Areas with these combined features may represent the most important nascent foci, fostering ongoing northward spread of this invasive species in the Neotropics.

    Space use patterns of two large carnivores: Puma ( Puma concolor ) and Maned Wolf ( Chrysocyon brachyurus ) in tropical agroecosystems

    Abstract: Mammalian carnivores are often vulnerable to the conversion of natural habitat. Although some species might be frequent in anthropogenic areas, it is not entirely clear how they use modified landscapes, particularly in tropical agroecosystems. Here, we investigated how Puma (Puma concolor) and Maned Wolf (Chrysocyon brachyurus) used three disturbed areas in southeastern Brazil. We sampled 205 camera stations and estimated species occupancy (Ψ) and detection probabilities (p), interpreted as probability of use and frequency of use, respectively. Our models predicted that both species extensively used the study areas (model-averaged probability of use of 0.65 for pumas and 0.50 for maned wolves). Puma frequency of use was higher in stations further from human structures and areas of savanna. Maned Wolf frequency of use was lower in forest-dominated stations and in a more protected and forested study area. Puma probability of use was high in stations closer to watercourses, while Maned Wolf probability of use was higher in unpaved roads and stations farther from human structures. Our findings suggest that pumas and maned wolves may be able to adapt their use of space in agroecosystems featuring riparian corridors and unpaved roads. Nevertheless, our data also reveal possible impacts to carnivore populations in these systems, such as the degradation of riparian environments, road mortality, and human construction avoidance. Thus, some caution is warranted in considering highly modified environments as safe habitats for large carnivores, until further data on the density and vital rates of these species in agricultural-dominated areas have been quantified.
