Contrasting risk patterns from human hunters and a large carnivore influence the habitat selection of shared preyNARA Subscribed
Spatial patterns of human hunting and predation risk are mediated by the physical landscape, with hunting risk often associated with different habitat features than those linked to large carnivores. Risk from hunters and carnivores also varies over time, and prey may adjust anti-predator strategies accordingly. We used GPS data from 17 female moose ( Alces alces ) tracked over two fall–winter seasons (2018–2020) in south-centr...
Survival and cause‐specific mortality rates are vital for evidence‐based population forecasting and conservation, particularly for large carnivores, whose populations are often vulnerable to human‐caused mortalities. It is therefore important to know the relationship between anthropogenic and natural mortality causes to evaluate whether they are additive or compensatory. Further, the relation between survival and environmental...
Aims The transcription factors bZIP19 and bZIP23 function as central regulators of the Zn deficiency response, and also as sensors of intracellular Zn concentration through their protein Zn-Sensor Motif (ZSM). While under Zn deficiency the target genes of bZIP19/23 are transcriptionally activated, under Zn sufficiency the binding of Zn 2+ ions to the ZSM halts gene expression. Mutations, including deletions, in the ZSM affect...
Backyard buzz: human population density modifies the value of vegetation cover for insect pollinators in a subtropical cityNARA Subscribed
Urbanisation drives overall declines in insect pollinators. Although urban green spaces can provide suitable habitat for pollinators much remains to be learned about how urban landscapes either promote or negatively impact pollinators. We investigated how backyard design, local (100 m) and landscape (500 m) scale vegetation cover and human population density were associated with non-eusocial native bee species, eusocial bees (...
Evaluating expert‐based habitat suitability information of terrestrial mammals with GPS‐ tracking dataNARA Subscribed
Aim Macroecological studies that require habitat suitability data for many species often derive this information from expert opinion. However, expert‐based information is inherently subjective and thus prone to errors. The increasing availability of GPS tracking data offers opportunities to evaluate and supplement expert‐based information with detailed empirical evidence. Here, we compared expert‐based habitat suitability info...
A breathing mask attenuates acute airway responses to exercise in sub-zero environment in healthy subjectsNARA Subscribed
Purpose Cold air exposure is associated with increased respiratory morbidity and mortality. Repeated inhalation of cold and dry air is considered the cause of the high prevalence of asthma among winter endurance athletes. This study assessed whether a heat- and moisture-exchanging breathing device (HME) attenuates airway responses to high-intensity exercise in sub-zero temperatures among healthy subjects. Methods Using a rando...
A heat and moisture-exchanging mask impairs self-paced maximal running performance in a sub-zero environmentNARA Subscribed
Purpose Heat-and-moisture-exchanging devices (HME) are commonly used by endurance athletes during training in sub-zero environments, but their effects on performance are unknown. We investigated the influence of HME usage on running performance at − 15 °C. Methods Twenty-three healthy adults (15 male, 8 female; age 18–53 years; $$\dot{V}{\text O}_{2peak}$$ V ˙ O 2 p e a k men 56 ± 7, women 50 ± 4 mL·kg −1 ·min −1 ) performed t...
We present quantitative reconstructions of regional vegetation cover in north‐western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k calendar years before present ( bp )] at a 1° × 1° spatial scale with the objective of producing vegetation descriptions suitable for climate modelling. The REVEALS model was applied on 636 pollen records fr...
Unexpected early extinction of the European pond turtle ( Emys orbicularis ) in Sweden and climatic impact on its Holocene rangeNARA Subscribed
Using ancient DNA sequences of subfossil European pond turtles ( Emys orbicularis ) from Britain, Central and North Europe and accelerator mass spectrometry radiocarbon dating for turtle remains from most Swedish sites, we provide evidence for a Holocene range expansion of the pond turtle from the southeastern Balkans into Britain, Central Europe and Scandinavia, according to the ‘grasshopper pattern’ of Hewitt. Northeastern E...
