The ferruginous duricrust ( canga ) in the Iron Quadrangle (IQ), Minas Gerais, Brazil, occurs within the Campo Rupestre and presents remarkable levels of endemism and species richness. Despite the recognized importance of microorganisms for the maintenance of this ecosystem, current molecular-based studies reveal that both the taxonomic composition and the ecological functions of the canga microbiome are undiscovered. In this...
Influence of Ketogenic Diet Lipid Composition on Anxiety-Like Behavior and Neurometabolic Profile in Healthy RatsNARA Subscribed
Ketogenic diets (KDs) modulate brain function, but how their fatty acid composition impacts behavior remains poorly understood. Male Wistar rats were fed a control diet (CD, n = 6), a classic ketogenic diet (CKD, n = 6) rich in saturated fatty acids (SAFAs), or a modified ketogenic diet (MKD, n = 6) enriched with polyunsaturated fatty acids (PUFAs) and DHA. After 100 days, both KDs induced similar ketosis and increased brain g...
Cytotoxic activity, phenolic content, and fatty acid of brown algae from tropical reefsNARA Subscribed
New cancer therapies development is a huge demand. This research evaluated cytotoxic activity against normal and cancer cells of brown algae (Dictyotales) extracts with high antioxidant activity. Canistrocarpus cervicornis , Dictyopteris delicatula and Lobophora variegata extracts from two beaches of Pernambuco were obtained by two serial maceration method: 1° Extraction—dichloromethane and methanol (2:1 v/v) and subsequently...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
Giants of the Amazon: How does environmental variation drive the diversity patterns of large trees?NARA Subscribed
For more than three decades, major efforts in sampling and analyzing tree diversity in South America have focused almost exclusively on trees with stems of at least 10 and 2.5 cm diameter, showing highest species diversity in the wetter western and northern Amazon forests. By contrast, little attention has been paid to patterns and drivers of diversity in the largest canopy and emergent trees, which is surprising given these h...
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...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
Rock n' Seeds: A database of seed functional traits and germination experiments from Brazilian rock outcrop vegetationNARA Subscribed
Advancing functional ecology depends fundamentally on the availability of data on reproductive traits, including those from tropical plants, which have been historically underrepresented in global trait databases. Although some valuable databases have been created recently, they are mainly restricted to temperate areas and vegetative traits such as leaf and wood traits. Here, we present Rock n' Seeds, a database of seed functi...
