Research identifies deep pools as critical ecological sanctuaries for <em>Steindachneridion melanodermatum</em>, the largest and most endangered catfish species endemic to the Lower Iguaçu River basin. The study, conducted between 2010 and 2016, found that 180 specimens were concentrated in 24 deep pools, with a notable preference for Poço Preto (P23) near Iguaçu Falls within Iguaçu National Park. Hydroacoustic surveys and fishing campaigns revealed that these deep habitats, ranging from 5 to 25 meters, are essential for the survival of this species, which has been decimated by habitat loss due to hydroelectric dams. The findings underscore the urgent need for conservation measures, including designating deep pools as protected sanctuaries, enforcing anti-poaching regulations, and preserving dam-free tributaries to prevent the extinction of <em>S. melanodermatum</em>.

A new study reveals that rock exhumation extends significantly farther inland—over 100 km—of the Fairweather fault compared to less than 30 km in the St. Elias syntaxial region, indicating widespread mid-Miocene to present-day deformation between the Fairweather and Eastern Denali faults. The research integrates detrital apatite and zircon fission track data from 27 modern drainages with existing geochronology, showing that the Eastern Denali fault acts as a backstop limiting late Cenozoic exhumation northeast of it. This challenges prior assumptions about deformation patterns in this region.

Urban conservation efforts in the historic Yenikapı neighborhood of Istanbul face significant challenges due to rapid development, including new constructions and public transport expansion. A study conducted between February and June 2019 identified key pressures affecting the area's integrity and authenticity, such as jarring architectural changes and town planning decisions. The research analyzed onsite conditions along Paşazade, İmrahor Hamamı, and Sepetçi Selim streets to assess the current state of conservation. Proposals for revitalization were suggested to preserve the neighborhood's historic character and cultural heritage value, emphasizing the importance of maintaining urban fabric while addressing modern development pressures.
