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 ...

Cave Palaeolithic of the Ural Mountains – a review

open access: yesBoreas, EarlyView.
The Ural Mountains are of fundamental importance for studying early human migrations along the geographical limits between Europe and Asia. Geological processes and past climates gave rise to numerous caves, mostly in Palaeozoic carbonate formations.

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Threatened or thriving? – The status of Serbian hoverflies on the IUCN European Red List of Hoverflies

open access: yesConservation Science and Practice, EarlyView.
Spatial distribution of Critically Endangered (CR) (a), Endangered (EN) (b), and Vulnerable (VU) (c) species in Serbia, showing overlap with Prime Hoverfly Areas (PHAs) and Protected Areas (PAs). Abstract Given the widespread decline of pollinators worldwide, assessing them using the IUCN criteria is crucial to understand their conservation status ...

Forest floor vegetation in Sweden [PDF]

open access: yes, 2012
In boreal forests, dwarf-shrubs (Vaccinium spp.) often dominate the forest floor and are key-stone species in ecosystems due to their importance for nutrient cycling and as a major food source for herbivores. Forestry affects the vegetation both directly

Environmental factors affect the condition of critically endangered freshwater pearl mussels by disrupting terrestrial–aquatic resource connectivity

open access: yesConservation Science and Practice, EarlyView.
This regional‐scale field study shows that critically threatened freshwater pearl mussels rely substantially on terrestrial organic matter, indicating strong connectivity between terrestrial and aquatic ecosystems. However, human pressures at the catchment scale reduced this resource connectivity.

VIABILITY OF PICEA PUNGENS F. GLAUCA IN THE KURTIN TYPE OF KRIVIY RIH PLANTATIONS [PDF]

open access: yes, 2018
A greater amount of natural dendroflora is not sufficiently resistant to technogenic conditions, therefore, the use of the introduced species has been started, in particular conifers.

Variable species establishment in response to microhabitat indicates different likelihoods of climate‐driven range shifts

open access: yesEcography, EarlyView.
Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically ...

Aspects of hybrid larch (Larix X eurolepis Henry) as a potential tree species in southern Swedish forestry [PDF]

open access: yes, 2003
The interest in growing hybrid larch (Larix × eurolepis Henry) in southern Sweden has increased in recent decades, one of its assumed advantages being high volume growth.
