A new study identifies five species of Phalloceros fish within the Ilha Grande Bay Hydrographic Region, Brazil—Phalloceros anisophallos, P. aspilos, P. enneaktinos, P. harpagos, and P. tupinamba—with two (P. harpagos and P. tupinamba) recorded for the first time in the area. The research expands the known geographic ranges of P. anisophallos and P. enneaktinos while revealing distinct morphological lineages based on female urogenital papilla structures, which influence species distribution patterns: sympatric occurrence is possible across different lineages, but allopatry is observed within the same lineage. The study analyzed 81 samples and provides a key for species identification, contributing to biodiversity documentation in this UNESCO-listed region.

Hanon volcanic crater on Jeju Island stands out as the only maar-type volcanic crater in South Korea, offering unique geological significance. It extends the spectrum of volcanic landforms on Jeju—from tuff rings to maars—and provides critical insights into past vegetation and climate change in East Asia through its sediment layers. Despite its scientific value, Hanon has suffered from human-induced damage, altering its landscape and ecosystems. To preserve its geoheritage while enabling sustainable use, the study proposes a detailed conservation and utilization plan. This includes designating protected zones based on heritage value, promoting eco-friendly tourism, educational activities like geology and ecology experiences, and developing cultural-ecological tourism. Integrating Hanon with nearby geological sites and infrastructure could further boost its potential as a geo-tourism cluster, enhancing both conservation efforts and regional economic benefits.
