Poor water quality significantly degrades coral biodiversity and promotes macroalgae growth on the Great Barrier Reef (GBR), according to a large-scale study. The research found that inshore reefs, characterized by lower water clarity and higher chlorophyll levels due to runoff, exhibit reduced richness in hard corals and phototrophic octocorals while experiencing a fivefold increase in macroalgal cover compared to offshore regions. Water quality explained 18–46% of the variation in these biotic groups, with spatial patterns also playing a role. The study identifies potential water quality guidelines—Secchi disk depth >10 meters and chlorophyll <0.45 g/L—that correlate with low macroalgal cover and high coral richness. Improving water quality on 23% of GBR reefs currently exceeding these thresholds could reduce macroalgae by 39% and boost hard coral and phototrophic octocoral richness by 16% and 33%, respectively, offering a target for pollution reduction strategies.

The Inca Empire's tribute system, as described in the 'Chronicle of Peru,' reveals a meticulous and adaptive approach to resource extraction from conquered provinces. A notable finding is the initial reliance on unconventional tribute items, such as live lice, which signified both the empire's ingenuity and its demand for contributions, even from the most resource-poor communities. This system evolved over time as provinces transitioned to more sustainable forms of tribute, like livestock and textiles. The study suggests that the Incas employed a network of royal roads—specifically four major routes—to administer this system efficiently, ensuring that tribute was collected uniformly across their vast empire. This method underscores the empire's organizational sophistication and its ability to integrate diverse regions into a cohesive economic framework.

Yellowstone National Park's reintroduction of wolves in 1995/96 appears to have triggered a secondary trophic cascade, indirectly boosting bison populations by reducing competition with elk. Wolves predating on elk altered elk behavior and reduced their numbers, increasing forage availability for bison. This interaction highlights an alternative top-down pathway where predators influence multiple trophic levels by mediating competitive dynamics between prey species. The study suggests that while wolves and bison can have significant ecological impacts, the benefits of bison restoration may be constrained in areas with low predation pressure, high bison densities, or limited movement. These findings underscore the importance of considering cascading effects when reintroducing ecologically influential species.

A critical review and worldwide correlation of ammonite biostratigraphy at the Pliensbachian Stage and Substage boundaries (Lower Jurassic) reveals key insights for global chronostratigraphic framework. The study establishes that the base of the Pliensbachian Stage, defined by the ammonite association <em>Bifericeras donovani</em> and <em>Apoderoceras sp.</em>, marks a significant boundary at Wine Haven, Yorkshire Coast (UK), coinciding with the Taylori Subchronozone. While the Lower-Upper Pliensbachian boundary remains undefined without a GSSP, potential candidates are identified across Euroboreal and Tethyan domains, including Dorset, UK, and regions in Spain, France, Italy, and Hungary. The research underscores ammonites as the most reliable fossil group for precise biostratigraphic correlation in the Lower Jurassic, building upon Oppel's foundational work (1856-58) to refine global chronostratigraphy.

A predominant presence of relatively insoluble mercury sulfide compounds, specifically cinnabar and metacinnabar, was identified across three major European mercury mining districts: Almadén (Spain), Idria (Slovenia), and Asturias (Spain). However, minor yet significant amounts of more soluble mercury compounds, such as chlorides and sulfates, were also detected in some samples. The study utilized synchrotron-based X-ray absorption near-edge spectroscopy (XANES) to analyze the speciation of mercury in various geological materials, including ore, calcines, dump material, soil, sediment, and suspended particles. Complementary single extraction procedures revealed that mercury mobility is strongly influenced by the concentration of chlorides and sulfates. Additionally, differences in the efficiency of roasting furnaces were observed among the three sites.
