A comparative analysis of three soil physical quality assessment methods—Florentino (1998), Andrews et al. (2002), and Peralta (2012)—revealed that the methodology proposed by Andrews et al. is most suitable for application in the Vertisol soils of Coro, Venezuela, due to its lack of dependency on local reference values. Key indicators such as aggregate stability (AD), effective pore volume (EPT), infiltration capacity at 20 cm depth (IC20), soil penetration resistance (ISP), and hydraulic conductivity (ks) were identified as the most robust for describing physical quality processes. The study also highlighted that extrapolating reference thresholds can lead to inaccurate estimations, potentially misrepresenting soil sustainability. Notably, moderate land-use intensity was found to offer the highest levels of physical sustainability across all methods, despite their differing approaches.

A comparative analysis of diatom algae diversity in six high-altitude Pamir lakes (3,729–4,213 m) reveals a remarkable conservation of species richness within Tajik National Park. Over 300 diatom species were identified across 466 samples collected between 2000 and 2018, with freshwater lakes Turumtaykul and Rangkul hosting the most diverse communities (171 and 162 species, respectively). Statistical floristic analysis suggests water salinity as a key regulator of diatom diversity in these ecosystems. The study highlights the stability of algal floras at the genus level, particularly <em>Pinnularia</em>, while also identifying two distinct floristic cores. These findings underscore the high evolutionary potential and conservation value of diatom species in protected high-mountain lakes.

A comparative habitat suitability analysis for wild water buffalo (Bubalus arnee) in Chitwan National Park, Nepal, identified the western sector grassland as a more preferable site (65.74% suitability) than the eastern sector (52.77%) for translocation efforts. The study assessed vegetation composition, slope, elevation, proximity to water sources, and human settlement, revealing Saccharum arundinaceum as the dominant tall grass species in both sectors, while tree dominance varied between Bombax ceiba (eastern) and Syzigium cumini (western). This research provides critical insights for conserving this endangered species, listed as 'Endangered' on the IUCN Red List since 1986, by guiding future translocation strategies to optimize habitat suitability.
