Aim We evaluate the phylogenetic relationships and taxonomic validity of Atlantic species of Labrisomus , identifying the lineages currently assigned to L. nuchipinnis , and assessing the role of biogeographic barriers in shaping the evolutionary history and geographic distribution of the genus. Location Atlantic Ocean. Taxon Labrisomus . Methods We assembled an extensive mitochondrial and nuclear DNA dataset of Atlantic speci...
Genome size (GS) is known to be highly variable among angiosperm species. However, this variation can also occur within species. Both interspecific and intraspecific variations in GS have been often found to be linked to phenotypic traits. Therefore, selective pressures acting on these target traits may indirectly shape GS evolution within and among species. However, the processes linking selective pressures to GS evolution ar...
Understanding the mechanisms underlying fast diversifications is central to evolutionary biology. This can be partly achieved by focusing on intrinsic reproductive barriers that emerge during early stages of divergence in fast‐radiating groups. Here, we explored the mechanisms underlying the divergence of two ecotypes of the Dianthus rupicola complex, which belong to the Eurasian clade of the hyperdiverse genus Dianthus , the...
Longevity record for the large-billed tern Phaetusa simplexNARA Subscribed
Environmental stress is a fundamental facet of life and a significant driver of natural selection in the wild. Gene expression diversity may facilitate adaptation to environmental changes, without necessary genetic change, but its role in adaptive divergence remains largely understudied in Neotropical systems. In Amazonian riparian forests, species distribution is predominantly influenced by species' waterlogging tolerance. Th...
Non-targeted metabolomic analysis of field-grown Coffea arabica cultivars reveals distinct leaf metabolic signaturesNARA Subscribed
This study conducted a non-targeted metabolomic analysis of five Coffea arabica L. cultivars grown in the field experimental areas of the Cerrado Mineiro (Minas Gerais State, Brazil) to identify their metabolic fingerprints. The five cultivars selected for this study were chosen based on their specific genetic backgrounds and traits, including disease resistance, productivity, and cup quality. A total of 463 metabolic features...
Artificial reefs featuring different shapes and functions have been deployed around the world, causing impacts on marine ecosystems. However, the approaches typically used to deliver topological complexity, flexibility and expanding requirements to prospective structures during the initial design stages are not well established. The aim of this study was to highlight the advantages and provide evidence on how modularity and pa...
The relative role of climate and biotic interactions in shaping the range limits of a neotropical orchidNARA Subscribed
Aim The centre‐periphery hypothesis (CPH) explains the decline of species abundance towards range limits and how this is driven by increasing ecological marginality. So far, most studies testing the CPH have focused on abiotic factors contributing to marginality, while the role of biotic interactions in limiting species distribution has been neglected. Here, we investigate both drivers' roles in restricting an orchid's range a...
NEOTROPICAL FRESHWATER FISHES : A dataset of occurrence and abundance of freshwater fishes in the NeotropicsNARA Subscribed
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distri...
Atlantic flower–invertebrate interactions: A data set of occurrence and frequency of floral visitsNARA Subscribed
Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time‐consuming, especially in the highly diverse tropics. We aimed to prov...
AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forestNARA Subscribed
The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from dif...
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; Procyon...
Fish biodiversity of Saint Peter and Saint Paulʼs Archipelago , Mid‐Atlantic Ridge, Brazil: new records and a species databaseNARA Subscribed
Saint Peter and Saint Paul's Archipelago (SPSPA), one of the smallest and most isolated island groups in the world, is situated on the Mid‐Atlantic Ridge, between Brazil and the African continent. SPSPA has low species richness and high endemism; nonetheless, the diversity of fishes from deep habitats (>30 m depth) had not been previously studied in detail. Several expeditions conducted between 2009 and 2018 explored the shall...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...
