Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

Wildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

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

Wildlife 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 ...

Characterization of Pinus spp needles and evaluation of their potential use for energy

, 2014
The demand for new energy sources is growing and awakening interest in the use of forest residues. Charcoal was prepared at carbonization temperatures of 500 oC, 600 °C and 700 °C in order to evaluate the potential use of Pinus sp needles for energy. The

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...
