A concerning trend of increasing short vegetation coverage at the expense of dense, arboreal-shrubby vegetation has been identified in the Pantanal wetland. Analysis of Normalized Difference Vegetation Index (NDVI) data from 2000 to 2015, combined with projections using DINAMICA EGO modeling, reveals that by 2030, 78% of the Pantanal could be dominated by grasslands or pastures, while only 14% would retain its original dense vegetation. This shift threatens the wetland's hydrological processes and flood pulse dynamics, critical to its ecological function. The study leverages open-source satellite data (MODIS) and transition matrix calculations to provide a data-driven strategy for conservation efforts.

A new assessment of seismic hazards in the Tongariro Volcanic Complex, New Zealand, reveals higher slip-rates (up to 2.6 ± 0.8 mm/yr) and larger potential earthquake magnitudes (M W 7.2 ± 0.1) than previously estimated for the region's faults. The study analyzed geomorphic surface offsets and fault trace geometry along four parallel normal faults—National Park, Waihi, Poutu, and Upper Waikato Stream—which collectively form the Tongariro Graben. While data suggest these faults could rupture as a whole or in shorter segments, the findings significantly elevate the seismic risk for the area, with implications for earthquake preparedness and hazard mitigation strategies.

Treated wastewater from the M'Zab Valley, Algeria, shows limited suitability for irrigation despite meeting some national and international standards. The study, conducted over two years (2013-2015), analyzed physical-chemical and bacteriological parameters to assess the effectiveness of a natural lagoon treatment system. While biological treatment reduced pollution, the water was deemed poor quality, only viable for salt-tolerant crops on well-drained soils with additional treatment. This research highlights the challenges of reusing treated wastewater in arid regions like the Sahara, where water scarcity is a critical issue.

A study on Ujung Kulon National Park (UKNP) reveals that visitor perceptions of facility completeness, fame of recreational areas, information services, and payment options are generally positive, though facility completeness lags behind. The research, conducted in 2015 with a sample of 150 visitors from 2014, found that the majority were young males aged 21–25, often students or foreign tourists, particularly from Asia, with first-time visitors typically staying over 10 hours. While UKNP is well-regarded for its recreational value and information provision, visitors perceive facilities as insufficient compared to their needs. The study used a descriptive-exploratory method with questionnaire-based data analysis.

Research at Pasargadae, an Achaemenian period UNESCO World Heritage Site, reveals that the site's architectural stones—previously classified by color (beige, dark-gray, and green-gray)—are distinct limestones with varying textures. Two types exhibit a compact structure, while the third is notably porous. Petrochemical analysis identified dolomite in some beige stone samples, though no salt was detected as a potential decay factor. Scanning electron microscopy (SEM) pinpointed calcite crystal dissolution as a primary cause of deterioration in dark-gray and green-gray stones. These findings provide critical insights for tailoring conservation strategies to preserve Pasargadae's historic integrity.

Ocean acidification (OA) poses significant threats to marine animals sensitive to carbonate chemistry changes, particularly in coastal upwelling regions like the Northwest coast of North America. A study on Olympic National Park's intertidal zone reveals that pH decline here occurs an order of magnitude faster than predicted models, raising concerns about biodiversity loss. Researchers assessed the sensitivity of over 700 marine invertebrate and algal species to pH changes using experimental evidence and expert opinion, reinforcing known OA vulnerability patterns for carbonate-structure-building taxa while highlighting gaps in data for understudied species. The study also projects potential impacts on rocky intertidal communities at four long-term monitoring sites based on their composition.
