Mining activities, primarily for building materials, further shape industrial management. The study identifies trends in balancing resource extraction with preservation, emphasizing the need for sustainable development in this understudied Arctic region.
Composition, structure and dynamics of poplar forests in the Lena Pillars National Park
Poplar forests within the Lena Pillars National Park exhibit high productivity and follow a predictable succession pattern, transitioning from herb-dominated young stands to coniferous forests as they mature. Research reveals consistent relationships between morphometric traits of poplar trees, providing insights into their ecological structure and dynamics. The study traces floodplain vegetation succession across three rivers (Buotama, Kuranakh, and Labyya), showing that overmature poplar stands are inevitably replaced by spruce or larch-spruce forests. These findings contribute to understanding the plant life of Yakutia's poplar forests and their potential future changes under varying environmental conditions.
Features of the lithological structure of the Lower Cambrian Pestrotsvet Formation near the Oi-Muran reef massif (Yakutia)
A detailed lithological analysis of the Lower Cambrian Pestrotsvet Formation near the Oi-Muran reef massif in Yakutia reveals rhythmic sedimentary patterns influenced by short-term transgressions and regressions. The formation exhibits thin alternations of limestone laminae, ranging from 3–5 cm to 40 cm in thickness, characterized by their light gray or pinkish-gray color and purity. These limestones contain abundant cyanobacteria and algal remains, suggesting their significant role in rock formation. Additionally, maroon marlstone intervals and ferruginous clay layers further define the sedimentary dynamics of this off-reef facies adjacent to one of Earth's oldest reef systems, the West Yakut Barrier Reef. This study enhances understanding of the geological processes shaping early marine ecosystems.

A rare and significant discovery of mass proliferation of benthic epilithic macrocolonies of the cyanobacterium Gloeotrichia cf. natans has been documented for the first time in water bodies within the continuous permafrost zone of the Buotama River, Lena Pillars Nature Park, Yakutia (Russia). This finding expands our understanding of this species' ecology and habitat preferences, which differ from more commonly studied planktonic cyanobacteria. The study characterizes the environmental conditions and chemical composition of the water, providing insights into the ecological niche of Gloeotrichia cf. natans. Importantly, no cyanotoxins (microcystins, cylindrospermopsin, saxitoxins, or anatoxin-a) were detected in the biomass using advanced analytical methods, including liquid chromatography–mass spectrometry and PCR techniques.
New Data on the Neopleistocene Mammal Fauna from the Region of the Natural Park “Lenskie Stolby” (Middle Lena River Basin, Yakutia)
A groundbreaking discovery reveals the presence of cave lions (Panthera spelaea) in the Lena Pillars Nature Park, marking the first documentation of this species in the Middle Lena River Basin. This finding, alongside 10 other large mammal species, enriches our understanding of the Neopleistocene fauna in Yakutia. Radiocarbon dating indicates that mass burials of these mammals predominantly formed during the Karginian interstadial (60–24 thousand years ago), a period previously identified as optimal for mammoth fauna distribution. The study also highlights shifts in the ecological preferences of Ovis nivicola compared to modern populations, providing new insights into Pleistocene ecosystems.
New Data on the Pleistocene Mammoth Fauna from the Territory of the Lena Pillars Nature Park (Middle Lena River, Yakutia)
A groundbreaking discovery reveals that the Lena Pillars Nature Park, a UNESCO World Heritage Site candidate, was home to a diverse Pleistocene mammoth fauna during the Karginian interstadial (60–24 thousand years ago). New radiocarbon dating and fossil remains identify 11 large mammal species, including the first recorded presence of cave lions in this region. The findings suggest that this period was optimal for mammoth fauna distribution in Yakutia, with ecological insights indicating that Ovis nivicola's Late Pleistocene habitat differed from its current range. This study significantly advances our understanding of Pleistocene biodiversity and environmental conditions in Northeast Asia.
The Discovery of Potentially Toxigenic Gloeotrichia CF. natans (Cyanobacteria) in the Continuous Permafrost Zone of Buotama River, Lena Pillars Nature Park in Yakutia, Was Made through the Observation of Epilithic Macrocolonies
Researchers report the first documented mass proliferation of benthic epilithic macrocolonies of potentially toxic cyanobacteria, Gloeotrichia cf. natans, in water bodies within a continuous permafrost zone—the Lena Pillars Nature Park in Yakutia, North-East Russia. This discovery underscores the ecological adaptability of this species under extreme environmental conditions, expanding our understanding of its habitat requirements and chemical composition. Despite its potential toxigenicity, no cyanotoxins (microcystins, cylindrospermopsin, saxitoxins, or anatoxin-a) were detected in the biomass using advanced analytical methods, including liquid chromatography-mass spectrometry and PCR. The study highlights the need for further investigation into benthic cyanobacteria, particularly as climate change alters vegetation periods and permafrost dynamics.

A new annotated list of 25 Orthoptera species, including 14 recorded for the first time from the Lena Pillars National Park (Yakutia, Russia) and adjacent territories, significantly expands the known fauna of the region. Among these, rare species such as Tetrix japonica and Arcyptera albogeniculata, along with Crysochraon dispar—a new addition to Central Yakutia's fauna—were identified. The study reveals that the park's Orthoptera community is dominated by Trans-Eurasian polyzonal (36%) and forest/forest-steppe species (24%), providing insights into the ecological composition of this UNESCO World Heritage Site. This research contributes to biodiversity documentation in one of Russia's most ecologically significant regions.
Parasite Fauna of Wood Bison (Bison bison athabascae Rhoads, 1897) Living in the Ust’-Buоtоmа Nursery, Lena Pillars Nature Park, Republic of Sakha (Yakutia)
A study of wood bison (Bison bison athabascae) in the Ust’-Buоtоmа Nursery, Lena Pillars Nature Park, Yakutia, identified six endoparasite species, including one protozoan and three helminths common to both wild and domestic ungulates in Yakutia and Canada. The findings suggest potential parasite exchange between natural and agricultural ecosystems, with implications for natural selection and livestock management. No zoonotic risks were detected, but parasites must be monitored to prevent clinical issues, particularly in young animals. The research supports reacclimatization efforts by providing insights into parasite dynamics in introduced populations.
Veterinary Sanitary Aspects of Acclimatization of Forest Bison in Yakutia
An international project aimed at restoring the population of forest bison, listed in Yakutia's Red Book since 2019, has shown successful acclimatization with a 12-14% annual population growth rate. The study confirms that natural and climatic conditions in Central Yakutia are ecologically compatible for these bison nurseries, supporting over 120 calves produced since the project's inception in 2006. However, the introduction process has led to increased helminth invasion, with imported bison experiencing both the death of gastrointestinal parasites and infection by local helminths. This dual impact raises concerns about the spread of parasitic diseases and potential new hosts for parasites that could affect agriculture and hunting, underscoring the need for continued research on helminth invasion during acclimatization.
