Scat DNA Applications for Low‐Density Carnivore Survey: Techniques, Efficiency and Future Directions

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
We reviewed 338 studies encompassing mostly Felidae, Canidae and Mustelidae species throughout the world, confirming scat DNA as a reliable genetic source for many applications. The findings here offer guidance for future studies on low‐density carnivores, helping to design cost‐effective research and improving data quality for conservation efforts ...

Spatial variability in iron nutritional status of large diatoms in the Sea of Okhotsk with special reference to the Amur River discharge [PDF]

open access: yes, 2014
The Sea of Okhotsk is known as one of the most biologically productive regions among the world's oceans, and its productivity is supported in part by the discharge of iron (Fe)-rich water from the Amur River.

Achieving Photo‐Activated Circularly Polarized Room Temperature Phosphorescence from Natural Biopolymers

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
This bio‐based chiral luminescent system exhibit photo‐activated CPRTP by anchoring arylboronic acids to hydroxypropyl cellulose (HPC) matrix. Notably, by controlling the drying kinetics, dynamic switchable CPRTP with opposite handedness can be obtained due to a balance of photonic bandgap (PBG) effect and chirality transfer effect induced by the HPC ...

Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli [PDF]

open access: yes, 2015
The neuroanatomy of hadrosaurid dinosaurs is well known from North America and Asia. In Europe only a few cranial remains have been recovered that include the braincase. Arenysaurus is the first European endocast for which the paleoneuroanatomy has been

A Universal Genomic Approach to Detect Hybridization Using MIPs: Insights From a Case Study on Pike

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Interspecific hybridization poses a major challenge to biodiversity conservation, as genetic introgression can threaten the persistence of native species. This phenomenon occurs when individuals from distinct species interbreed, producing hybrids with a combination of genetic traits from both parents. The implications are especially concerning

Bioarchaeological perspective on the expansion of Transeurasian languages in Neolithic Amur River basin

open access: yesEvolutionary Human Sciences, 2020
Owing to the development of sequencing technology, paleogenomics has become an important source of information on human migration and admixture, complementing findings from archaeology and linguistics.

Sunlight‐Driven Fixation of CO2 to Cyclic Carbonates Using Carbon Dots as a Photothermal Catalyst

open access: yesExploration, Volume 6, Issue 1, February 2026.
The first example using carbon dots (CDs) for coupling CO2 with epoxides to generate cyclic carbonates in a metal‐, additive, solvent‐ and electricity input‐free manner under sunlight via photothermal catalytic route is developed. The CDs exhibit highly efficient solar‐to‐thermal conversion with an efficiency of 54%, providing thermal energy for ...

Retrospective Analysis of Enterovirus Infection Morbidity Rate in the Territory of the Amur Region and Peculiarities of Epidemic Process in the Period of Large-Scale Flood

open access: yesПроблемы особо опасных инфекций, 2014
There has been observed a tendency to increment of enterovirus morbidity rate over the past seven years. Foci of this infection have been formed in the area from time to time, with minor forms of the disease being predominant in clinical findings ...
