Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

THERMAL HISTORY OF THE GULI PLUTON (NORTH OF THE SIBERIAN PLATFORM) ACCORDING TO APATITE FISSION-TRACK DATING AND COMPUTER MODELING

open access: yesГеодинамика и тектонофизика, 2020
We present the first results of fission-track dating of apatite monofractions from two rock samples taken from the Southern carbonatite massif of the world’s largest alkaline ultrabasic Guli pluton (~250 Ma), located within the Maymecha-Kotuy region of ...

Diversity and distribution of Cambrian acritarchs from the Siberian and East-European platforms - a generalized scheme

open access: yesCarnets de Géologie, 2005
The study of acritarchs in Russia was initiated by Naumova and Timofeev in the early 50s. Their initial results showed the high potential of these microfossils for biostratigraphy and was followed by a remarkable degree of research activity in the 70s ...

Diamonds from low-grade kimberlite

open access: yesРуды и металлы, 2022
Based on exploration and sampling work on the Siberian platform (SP) the uneven diamond content of various diatremes was established. During the exploration apart from the pipes with high or medium content of a useful component also the diatremes with ...

Geochemistry of neoprotherosoic organic matter in the southeast of the Siberian platform

open access: yesGeoresursy, 2020
In the Neoproterozoic of the Aldan-Maya depression, the rocks of the Malgin (MF), Tsipanda (TF) and Kumakha (KF) Formations are enriched in organic matter (OM) and can be classified as source rocks. High generation potential is typical for the MF and TF (
