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...
The vermetid Vermetus triquetrus , commonly found on intertidal hard substrates in the Mediterranean Sea and the Portuguese coast, remains an underexplored marine resource. This study aimed to determine the total polyphenol content, fatty acid (FA) composition, and biological activity (antioxidant and anti-inflammatory properties) in the visceral mass and the head-foot part of this sessile gastropod from a population collected...
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...
Quiet Signals of Burmeister's Porpoises ( Phocoena spinipinnis ) Recorded in Chile and PeruNARA Subscribed
Burmeister's porpoises are cryptic and challenging to detect visually. More information on their acoustic signals could facilitate the use of passive acoustic monitoring (PAM) and help to better understand their ecology. Here, clicks were recorded from two different Burmeister's porpoise populations, one in Chile and the other in Peru, using a 4‐channel hydrophone array and a single‐channel hydrophone recorder. Burmeister's po...
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...
