Genetic association of productive traits, carcass measurements and age at first calving in the genetic evaluation of the Nellore breedNARA Subscribed
The aim was to evaluate the genetic association between sexual precocity and productive performance in Nellore cattle. Records of standardized body weights at 120 (W120), 210 (W210), 365 (W365), and 450 (W450) days of age, Longissimus Muscle Area (LMA), backfat thickness (BFT), and age at first calving (AFC) were used. The mixed linear model included the fixed effects of contemporary groups (composed of herd, year, and season...
Conventional wastewater treatment plants often struggle to manage episodic “shock loads” of emerging contaminants, particularly persistent preservatives such as methylparaben (MeP) and antimicrobial compounds such as trichlorocarbanilide (TCC). While most biodegradation studies focus on trace environmental concentrations, industrial effluents may contain substantially higher contaminant loads that challenge biological treatmen...
Reaction norm models for the evaluation of reproductive and productive performance in Nellore cattleNARA Subscribed
This study evaluated genotype × environment interactions (G×E) in Nellore cattle for growth, reproductive, and carcass traits using reaction norm models. We analyzed the records of body weight and scrotal circumference at 12 and 18 months. (W365, W450, SC365, SC450), as well as loin eye area (LEA) and subcutaneous fat thickness (SFT), from herds across different Brazilian states were analyzed. A hierarchical one-step reaction...
A geological and geophysical database for the assessment of offshore freshened groundwater resourcesNARA Subscribed
Fresh groundwater resources in coastal regions are vital for modern society, but are under considerable pressure due to population growth, seasonal peaks in demand, pollution and climate change. In recent years, interest in offshore freshened groundwater (OFG) has surged, as potential resource for addressing these challenges. Recent studies have documented OFG occurrences on many continental margins and islands, with global vo...
Tropical forest succession increases tree taxonomic and functional richness but decreases evennessNARA Subscribed
Aim Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered into local communities based on their traits. Here, we assess successional changes in taxonomic and functional richness, evenness and redundancy along gradients of climate, soil pH and forest cover. Location Neotropics. Time period Last 0–100 years. Major taxa studied Trees. Methods We used 22 forest...
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...
A walk in the PARC: developing and implementing 21st century chemical risk assessment in EuropeNARA Subscribed
Current approaches for the assessment of environmental and human health risks due to exposure to chemical substances have served their purpose reasonably well. Nevertheless, the systems in place for different uses of chemicals are faced with various challenges, ranging from a growing number of chemicals to changes in the types of chemicals and materials produced. This has triggered global awareness of the need for a paradigm s...
The international development community is off-track from meeting targets for alleviating global malnutrition. Meanwhile, there is growing consensus across scientific disciplines that fish plays a crucial role in food and nutrition security. However, this ‘fish as food’ perspective has yet to translate into policy and development funding priorities. We argue that the traditional framing of fish as a natural resource emphasizes...
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,...
