IDENTIFYING UPPER MIOCENE – LOWER PLIOCENE LACUSTRINE SEDIMENTS IN DRY TUNKA BASIN OF THE BAIKAL RIFT ZONE

open access: yesГеодинамика и тектонофизика, 2020
We present results of lithogeochemical, diatomic and palynological studies of sediments from the Tunka-13 well that was drilled in the southeastern part of dry Tunka basin in the Baikal rift zone.

Joint Angular Excursions and Angular Range Utilization During Stance‐Phase Locomotion in Terrestrial Mammals: A Comparative Morphofunctional Data Set

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
This study quantifies stance‐phase joint angular excursions and angular utilization (AUI%) during walking in 182 terrestrial mammal species. Across mammals, total limb excursion during stance (TAE) decreases with increasing body mass, whereas AUI% remains broadly conserved, indicating similar proportional use of summed joint excursions to generate net ...

Occurrence of Crocuta (Carnivora, Hyaenidae) from a potential Middle Pleistocene site at Pirro Nord (Apricena, southern Italy)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Pirro Nord quarry has yielded evidence of one of the earliest hominin presences in western Europe, accompanied by an extremely rich and diverse collection of vertebrate remains, including amphibians, reptiles, birds, and small and large mammals.

Environmental and temporal factors affecting record white‐tailed deer antler characteristics in Ontario, Canada

open access: yesThe Journal of Wildlife Management, EarlyView.
Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.

THE MIOCENE AND DEVONIAN MAGMATISM AT THE JUNCTION BETWEEN THE TUVA-MONGOLIAN MASSIF AND SIBERIAN CRATON: COMMON COMPONENT OF MANTLE SOURCES AND ITS ORIGIN

open access: yesГеодинамика и тектонофизика, 2015
Devonian dikes of the Urik-Belaya and Shagayte-Gol-Urik zones and Miocene lavas of the Urik volcanic field are spatially associated with each other at the structural junction between the Neoproterozoic Tuva-Mongolian massif and Siberian craton.

Carya nux‐taurinensis comb. nov., a fossil‐species incorporating Carya globosa (Juglandaceae)

open access: yesTAXON, EarlyView.
Abstract The type material of the almost forgotten fossil‐species Juglans nux‐taurinensis is newly analysed, a lectotype is designated, and new conspecific material detected at the Italian type locality La Morra is described. We show that Juglans nux‐taurinensis must be reassigned to Carya because the locule cast of the nutshell shows two inner ...

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

open access: yesInsect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.
