Rancho La Brea (RLB) in Los Angeles, USA, is an iconic fossil locality, owing to the high number and diversity of Quaternary vertebrate remains and their excellent preservation. More than a century of study, focused predominantly on large mammals, has provided valuable information along different lines of research, including taxonomy, taphonomy, isotopic ecology, functional morphology, and paleopathology. In order to develop a...
Global mercury concentrations in biota: their use as a basis for a global biomonitoring frameworkNARA Subscribed
An important provision of the Minamata Convention on Mercury is to monitor and evaluate the effectiveness of the adopted measures and its implementation. Here, we describe for the first time currently available biotic mercury (Hg) data on a global scale to improve the understanding of global efforts to reduce the impact of Hg pollution on people and the environment. Data from the peer-reviewed literature were compiled in the G...

Bacterial diseases of tilapia, their zoonotic potential and risk of antimicrobial resistanceNARA Subscribed
Tilapia culture is an important source of income and nutrition to many rural families. Since 2000, the production of tilapia increased and reached domestic and global markets. Major farmed species is Nile tilapia ( Oreochromis niloticus ), in earthen ponds and cage cultures. Intensification contributed to global tilapia disease outbreaks, with bacterial infections causing mortalities and morbidities, threatening sustainable pr...
Genetic variants of K udoa septempunctata ( M yxozoa: M ultivalvulida), a flounder parasite causing foodborne diseaseNARA Subscribed
Foodborne disease outbreaks caused by raw olive flounders ( Paralichthys olivaceus ) parasitized with Kudoa septempunctata have been reported in Japan. Origins of olive flounders consumed in Japan vary, being either domestic or imported, and aquaculture‐raised or natural. Although it is unknown whether different sources are associated with different outcomes, it is desirable to identify whether this is the case by determining...
After conditioning Nile tilapia Oreochromis niloticus for 2 weeks, the photoperiod regime of 12 tanks of fish was changed to a 6L : 6D photoperiod while 12 further tanks were retained on the conditioning photoperiod regime (12L : 12D). Blood samples were collected 3 days (first sampling) and 3 months (second sampling) after changing the photoperiod regime. Blood was collected at 6 h intervals from both photoperiod regimes (100...
