Behavioural responses of a gamebird to human encounters across the hunting season

open access: yesWildlife Biology, EarlyView.
We examined the behavioural adaptation of rock ptarmigan Lagopus muta in response to human encounters across the hunting season. We conducted disturbance experiments in two different parts of the species' range, in subarctic (Iceland) and in alpine (Italy) habitats.

Badania kariologiczne brzozy ojcowskiej i jej potomstwa [Karyological studies on Betula oycoviensis Besser and its progeny]

open access: yesActa Societatis Botanicorum Poloniae, 2015
In the progeny of Betula oycoviensis pollinated with the pollen of Betula oycoviensis three groups were distinguished: oycovlensis type, verrucosa type, and „nova" type (a small dwarf birch). The number of chromosomes determined in the parental specimens

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Аминокислоты бересты Betula pendula и Betula pubescens

open access: yesМедицина и образование в Сибири, 2015
Объектами исследования служили образцы бересты березы повислой и березы пушистой, собранные из различных точек ареала растений и с разных участков ствола, расположенных на разной высоте от основания. Установлено наличие 14-ти аминокислот. Состав компонентов аминокислот в образцах бересты березы повислой и березы пушистой одинаков в пределах одного ...

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.

Middle and late Holocene vegetation and landscape evolution of the Scheldt estuary : a palynological study of a peat deposit from Doel (Belgium) [PDF]

open access: yes, 2011
Local and regional environmental conditions for the south-eastern Scheldt estuary during the middle and late Holocene period have been reconstructed based on pollen analysis, loss-on-ignition and radiocarbon dating of a sediment core from Doe (N-Belgium)

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China

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 ...

From low to high elevations, flowers adapt traits and phenology to climate, but phenology‐trait relationships weak

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowering phenology is central to plant reproductive success and can relate to morphological traits such as size and quality of flowers, but phenology–trait associations of flowers remain unclear.

Changing food availability and its effect on the heritability of offspring size in woodland passerine birds

open access: yesJournal of Animal Ecology, EarlyView.
Vatka et al. investigated how changing food abundance affects evolutionary potential of offsprings' body size traits in two woodland passerines. Food availability increased over the 25‐year‐long study period, accompanied by increases in body mass.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...
