Winter Track Survey of the Amur Tiger (Panthera tigris altaica) in the Southwest Primorsky Province of Russia 俄罗斯滨海边疆区西南部东北虎 (Panthera tigris altaica) 冬季足迹调查

open access: yesWildlife Letters, EarlyView.
In the winter of 2021/2022, a winter track survey revealed 43–46 tigers (without cubs) in 5.4 thousand km2 of suitable habitats in the Southwest Primorsky Province of Russia. In the same period, a network of camera traps registered 54 adult/subadult tigers here.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...
