In order to ascertain if Cu, Fe, and Zn are differentially accumulated in fish tissues, metal concentrations were measured in the muscle and liver of bycatch fish from the states of Sinaloa (189 specimens, 7 species) and Guerrero (152 individuals, 8 species) in the Mexican Pacific Coast during March and November 2011. Additionally, metal levels were compared with the maximum allowable limits set by international legislation and contrasted with similar ichthyofauna from other regions. Liver had more elevated concentrations of Cu (Sinaloa 28.3, Guerrero 16.3 μg g), Fe (Sinaloa 1098, Guerrero 636 μg g), and Zn (Sinaloa 226, Guerrero 186 μg g) than the muscle in fish from both studied areas. The relative abundances of analyzed metals in both tissues was Fe > Zn > Cu. As far as limits set by international legislation (Australia, India, New Zealand, Zambia), measured concentrations of Cu in the edible portion of fish were not found to be above the set values. In the case of Zn, the maximum allowable limits set by international legislation were exceeded by the Peruvian mojarra Diapterus peruvianus from Guerrero state (Mexican Pacific). No limits exist for Fe in the edible portion of fishery products in the national and international legislations.

Gratitude is associated with increased social integration, which may counter the loneliness stemming from repeated peer victimization. The gratitude youth feel after different types of bystander action may depend on which behaviors are most congruent with personal beliefs. Face and honor cultures provide social norms for expectations and interpretations of behavior, including how to act during and after interpersonal conflict.

Tropical cyclones (TCs) are one of the major natural hazards to island and coastal communities and ecosystems. However, isotopic compositions of TC-derived precipitation (P) in surface water (SW) and groundwater (GW) reservoirs are still lacking. We tested the three main assumptions of the isotope storm "spike" hypothesis (sudden spikes in isotopic ratios).

Recent ichthyological surveys in southern Mexico resulted in the unexpected discovery of populations of P. chimalapensis outside its distribution range, broadening its extent of occurrence to a total of three river basins (Coatzacoalcos [original], Grijalva, Ostuta) and two versants (Atlantic [original] and Pacific). The taxonomic nature of these populations was further investigated using comparative genetic data in a phylogenetic framework.

Article Synopsis
- Endemic species, particularly butterflies in Mexico, are highlighted for their unique histories and the vital information they provide about their local environments, with this study being the first comprehensive compilation on this topic.
- The research analyzed 272 endemic butterfly taxa, creating distribution maps and examining their biogeographical patterns across various ecological regions, revealing that most endemic species are found in the southwestern part of the country.
- The study identifies sampling biases and under-researched areas, suggesting that the Sierra Madre Occidental should be the main focus for future research efforts on endemic butterflies to enhance knowledge and conservation strategies.
Article Synopsis
- The text discusses the importance of forecasting future health issues in the USA for effective planning and public awareness regarding disease and injury burdens.
- It describes the methodology for predicting life expectancy, cause-specific mortality, and disability-adjusted life-years (DALYs) from 2022 to 2050 using the Global Burden of Diseases framework.
- The forecasting includes various scenarios to assess the potential impacts of health risks and improvements across the country, focusing on demographic trends and health-related risk factors.
