Summary: Understanding the space use and movement behavior of tiger sharks is crucial for their conservation. This study found that Bimini serves as an important pupping ground for tiger sharks, with some individuals showing long-term site fidelity. The study also revealed that larger individuals are more likely to disperse from Bimini to other areas in the western North Atlantic.

Summary: Understanding dispersal in large marine fauna is necessary for conservation, as movement patterns vary by sex and life stage. This study used genetic and tracking data to evaluate reproductive dispersal in tiger sharks in the northwestern Atlantic. The findings show that lumping individuals from different life stages in genetic studies may obscure fine-scale genetic structure.

Summary: The lifelong tooth replacement in elasmobranch fishes has led to the accumulation of a large number of teeth, making tooth morphology an important character for taxonomic descriptions, phylogenetic analyses, and understanding the evolutionary history of these fishes. This study focuses on the dental heterodonty in the tiger shark, revealing gradual ontogenetic shape changes and providing a comprehensive description of embryonic dental morphologies. It contributes to our understanding of dental traits across ontogeny in the tiger shark and serves as a baseline for further studies on dental variation in sharks.

Summary: This study investigated the nitrogen and oxygen stable isotope ratios of nitrate in four different types of advanced wastewater treatment processes, revealing spatial variations within the treatment steps. The study found that the changes in delta N-15 and delta O-18 of nitrate were related to reactor conditions and the order of treatment processes. Additionally, the study concluded that stable isotope signatures reflected treatment efficiency and effluent characteristics, with the modified Bardenpho process showing higher nitrogen removal efficiency.

Summary: Human activities have caused serious soil mercury pollution in industrial areas worldwide. Mercury contamination in soil was found to be significantly elevated in areas of mercury mining, gold mining, and zinc smelting, with atmospheric deposition speculated as the main pathway for soil mercury contamination. Speciation and concentration of mercury in emission gas are crucial factors for mercury pollution in surrounding soils.

Summary: Over the last century, shark populations have declined due to overexploitation and the use of shark control programs. A study in eastern Australia found a significant change in the genetic composition of tiger sharks born between 1939 and 2015, suggesting a shift in the relative contribution of two cryptic populations.

Summary: By analyzing the nitrogen and mercury isotopes of eels and pike, we found that pike has consistent mercury concentration and ecological traits, making it an effective bioindicator for mercury. Eels, on the other hand, better capture site-specific mercury sources based on their mercury concentration and feeding behavior.

Summary: Researchers have reported the first observation of a potential neonate tiger shark at Cocos Island in the Eastern Tropical Pacific (ETP), as well as detecting potentially pregnant female individuals through the use of baited remote underwater video stations (BRUVS). This discovery suggests that tiger sharks may be using the island for reproduction, although it remains unclear whether this is an isolated event or a regular occurrence.

Summary: We conducted an analysis on a tiger shark bite on a snorkeler, which estimated the shark to be 2.8 meters in total length. The removal of the lower part of the leg indicates a predatory motive for the bite. This is the first recorded tiger shark bite in French Polynesia waters in the past 75 years.

Summary: This study investigated the global population genomics of tiger sharks, finding strong genetic differentiation between western Atlantic and Indo-Pacific sharks, as well as low population differentiation between tiger sharks from the Hawaiian archipelago and sharks from the Indian Ocean. The results suggest a need to prioritize conservation of the highly genetically differentiated Atlantic and Indo-Pacific populations of tiger sharks, with targeted management attention to tiger sharks in the Hawaiian archipelago.

Summary: Billions of dollars are lost annually in the US due to fuel tax fraud. Compound specific isotope analysis (CSIA) using isotope ratio mass spectrometry (IRMS) was investigated to identify fuel fraud. Variability in isotopic ratios of toluene samples from different sources was found, enabling the differentiation of potential fuel adulterants. Selective solvent extraction, ionic liquid coated solid phase microextraction (SPME), and a combination of the two were identified as effective methods for aromatic isolation and analysis.

Summary: Older adults with multiple systemic diseases often require treatment with multiple drugs, leading to significant concerns about anticholinergic adverse effects. A pharmacological evidence-based burden scale that considers pharmacokinetic and pharmacodynamic factors is expected to be a more optimal tool for assessing the anticholinergic burden and reducing the risk of adverse events in the poly-medicated elderly.

Summary: This study evaluated the regional source dietary exposure of anthropogenic organochlorine pesticides (OCPs) and halogenated natural products (HNPs) in Japan. The results showed that dicofol and endosulfan were the main OCPs, while Cl-7-MBP and Br4Cl2-DBP were the main HNPs. The exposure levels of these compounds differed from those of other OCPs and HNPs, indicating different sources. Further research is needed to identify the sources of these compounds and assess their risks to human health.

Summary: Phenology monitoring is important for understanding forest functioning and climate impacts. This research compares the phenological behavior of European beech forests using Tree-Talker (TT+) and Sentinel 2 satellite data. The study finds differences in the information derived by the two sensor types, particularly in terms of season length, phenology changepoints, and leaf period variability. TT+ with its higher temporal resolution demonstrates precision in capturing the phenological changepoints, especially when satellite image availability is limited.
