The Return of the Allis Shad (Alosa alosa) to the Lower Navigable Reaches of the Seine: Locks Play a Role

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT In France, it is estimated that shads (Alosa spp.) have lost 69% of their historical range, mainly due to disrupted river connectivity. After an absence of one century, signs of their return in the Seine River have been recorded over the past two decades: adult and juvenile specimens have been caught by anglers or recorded at video‐counting ...

Harvest-Time Protein Shocks and Price Adjustment in U.S. Wheat Markets

open access: yesJournal of Agricultural and Resource Economics, 2009
Dynamic relationships among three classes of wheat are investigated using threshold VAR models that incorporate the effects of protein availability. Changes in the stock of protein are found to generate significant responses in the prices of hard red ...

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

open access: yesWildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Detection‐Dog‐Guided Camera Placement Increases Efficiency of Surveys for Long‐Tailed Weasels (Neogale frenata) 利用探测犬引导布设相机可提升长尾鼬调查效率

open access: yesWildlife Letters, EarlyView.
By comparing widespread surveys with randomly placed cameras to a protocol pairing detection dogs with cameras, we found that the detection‐dog‐guided camera survey had approximately 33 times greater detections with fewer camera nights and reduced survey costs. We recommend using detection dogs to identify areas to focus camera trapping. ABSTRACT Multi‐

Methods of Calculating Ionization Energies of Multielectron (Five or More) Isoelectronic Atomic Ions

open access: yesThe Scientific World Journal, 2013
We have previously used simple empirical equations to reproduce the literature values of the ionization energies of isoelectronic sequences of up to four electrons which gave very good agreement.

The oxygen and pressure physiology of upper elevational range limits in insects

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is widely expected to cause montane insects to shift upslope, and there is good evidence that some populations are doing so. Nevertheless, patterns are mixed—with evidence supporting upslope, downslope or even no movement of both lower and upper range ...
