Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture-recapture and photographic identification (photo-ID), which involves processing considerable quantities of photographic data. To ease this burden, agencies increasingly rely on automated identification (ID) algorithms.

- The study examined the fatty acid profiles and persistent organic pollutant (POP) levels in humpback whales from different regions of the Southern Ocean, Chile, and Brazil.
- Significant differences were found in the fatty acid compositions, with whales in the Strait of Magellan showing a diet high in higher trophic level prey, while those from the Antarctic Peninsula and Brazil reflected a krill-based diet.
- Elevated concentrations of pollutants, especially PCBs, were observed in whales from the Strait of Magellan, indicating a connection between their dietary habits and exposure to contaminants.
Article Synopsis
- The study investigated the effects of contaminated groundwater from a legacy pesticide plant on male and female Sprague Dawley rats, focusing on toxicity over a 60-day exposure period.
- Rats exposed to higher concentrations of groundwater (1% and 10%) experienced significant liver damage and other health issues, including reduced plasma albumin and signs of kidney damage.
- Findings indicate that both liver and testicular toxicity were dose-dependent, highlighting the importance of using innovative assessment methods for understanding the risks of exposure to complex contaminant mixtures.
