Summary: Contrary to other places in the world, the mangrove coverage in Aotearoa, New Zealand has been increasing steadily since the 1900s. The intentional removal of mangroves in Aotearoa New Zealand is often driven by a desire to eliminate muddy sediment from areas that were originally dominated by sand. This study examines the long-term effects of mangrove removal in Waikaraka Estuary, showing limited geomorphic and ecologic changes over a decade.

Summary: The study reveals that subtropical mangrove estuaries in southern Texas play a crucial role in methane cycling, influenced by tidal processes, amplitude, and topographic characteristics. Normally, these mangroves are a weak source of methane emissions, but after a severe cold-freezing event, the mangrove dieback resulted in significantly elevated methane emissions. This study highlights the importance of management considerations for blue carbon projects in vulnerable areas.

Summary: The study showed that the effects of seawalls on wrack composition and dynamics in mangrove forests may be weaker compared to unvegetated shorelines. This could be due to the autochthonous source of wrack in mangrove forests, the habitat structure minimizing hydrodynamic impacts, and differing reasons for constructing hard structures in different energy settings.

Summary: Mangrove estuaries are economically valuable and biologically diverse coastal ecosystems. However, knowledge about emerging pollutants in mangrove estuaries is limited. This study investigated PFAS concentrations in a continuous river-mangrove estuary-bay system in China, revealing a declining trend of PFAS concentrations from the river to the bay. The primary sources of PFAS pollution were identified as wastewater treatment plant effluent, domestic and production wastewater discharge, aqueous film-forming foam emissions, and fluorochemistry industry wastewater. PFAS pollution in the mangrove creek was mainly influenced by domestic and production wastewater discharge, particularly during the rainy season.

Summary: This study investigated the geochemical dynamics of sediment organic matter in mangrove wetlands and found significant exchanges of mangrove OM with marine and mixed forest OM. Despite these exchanges, distinct values of delta C-13, TOC and C/N were observed in modern surface sediments of different vegetational zones, confirming their usefulness as coastal environmental proxies. The proxies, combined with chronologies based on radiocarbon, 210 Pb and 137 Cs analyses, were successfully used to reconstruct the depositional history of the mangrove wetland, providing new insights into environmental responses to natural and anthropogenic drivers.

Summary: A 1-year field monitoring program was conducted to study the seasonal variation in N2O fluxes in two different types of mangrove wetlands. The study found that the island-type mangrove wetland had higher levels of heavy metal(loid) contamination and lower levels of salinity compared to the small bay-type wetland. The N2O fluxes showed a similar seasonal variation pattern in both wetlands, with higher fluxes observed in summer. However, the average N2O flux in the island-type wetland was lower than in the small bay-type wetland. The study also found that N2O flux was closely related to soil-borne heavy metal(loid)s and that the activity of anammox bacteria played a key role in affecting the spatial variation of N2O fluxes in the mangrove soils.

Summary: This study investigated a tidal creek in China with a significant mangrove-salt marsh gradient, revealing differences in nitrogen and phosphorus cycling between mangrove and salt marsh that have significant implications for coastal waters. Denitrification dominated nitrogen removal in both mangrove and salt marsh, with salt marsh having less capacity for ammonium production. The study highlighted the impact of mangrove-salt marsh ecotone on coastal eutrophication potential by modifying nutrient stoichiometry and porewater exchange.

Summary: The study reveals thresholds for physiological viability and vegetation- climate feedbacks in Earth's tropical forests during Late Paleozoic Ice Age, leading to turnover of plant species. The shift to more drought-tolerant plants provided ecological advantages, but their impact on climate was limited by aridity and vegetation density. Atmospheric pCO2 has a larger effect on physiological functioning than pO2 in these extinct plant species.

Summary: Our study evaluates the influences of elevation and climate on the distribution of wetland and dryland biomes during the Pennsylvanian and early Permian in tropical Pangea. Two models, the upland model and the climate model, are proposed to explain the distribution patterns of vegetation under different environmental conditions. The findings suggest that environmental changes and climatic oscillations played a significant role in shaping the floral patterns in tropical regions during the late Paleozoic era.

Summary: Paleobotanical taxonomy primarily focuses on fragmented organ-species, each bearing a Linnaean binomial, which may actually consist of multiple valid binomials. There are two opposing logical approaches to clarifying this complex situation: creating additional formal names for organ-species found in multiple modes of preservation, or gradually rationalizing parallel preservational taxonomies.

Summary: Understanding the carbon perturbation events and their effects on the Earth system is crucial for studying how the Earth responds to abrupt warming. This study investigates an abrupt carbon perturbation and global warming event that occurred during a paleo-glacial state using an integrated proxy and modeling approach. The results show significant isotopic excursions coinciding with a doubling of atmospheric CO2 partial pressure and a biodiversity nadir. Earth system modeling suggests that widespread anoxic conditions during this global warming event can be attributed to enhanced thermocline stratification and increased nutrient fluxes.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
