The Journal of Wildlife Management, EarlyView.Although evidence suggests >90% of the North American wood duck population nests in natural tree cavities, few studies have investigated the occurrence of these cavities across their southern breeding range. We aimed to determine forest and tree characteristics associated with the presence of cavities and cavities suitable for wood duck nesting and our

Aquatic heatwaves increase surface chlorophyll concentrations in experimental and reference lakes
Limnology and Oceanography Letters, EarlyView.Abstract Aquatic heatwaves are increasing in frequency, intensity, and duration worldwide. While increases in mean water temperatures are linked to enhanced phytoplankton biomass, it is unclear how heatwaves alter phytoplankton dynamics in lakes at an ecosystem scale.

Re-identification of c. 15 700 cal yr BP tephra bed at Kaipo Bog, eastern North Island: implications for dispersal of Rotorua and Puketarata tephra beds. [PDF]
, 2003 A 10 mm thick, c. 15 700 calendar yr BP (c. 13 100 14C yr BP) rhyolitic tephra bed in the well-studied montane Kaipo Bog sequence of eastern North Island was previously correlated with Maroa-derived Puketarata Tephra.

On some properties of the asymptotic Samuel function
Mathematische Nachrichten, EarlyView.Abstract The asymptotic Samuel function generalizes to arbitrary rings the usual order function of a regular local ring. Here, we explore some natural properties in the context of excellent, equidimensional rings containing a field. In addition, we establish some results regarding the Samuel slope of a local ring.

Recent atmospheric Pb deposition at a rural site in southern Germany assessed using a peat core and snowpack, and comparison with other archives [PDF]
, 2005 In a peat bog from Black Forest, Southern Germany, the rate of atmospheric Pb accumulation was quantified using a peat core dated by 210Pb and 14C. The most recent Pb accumulation rate (2.5 mg m−2 y−1) is similar to that obtained from a snowpack on the ...

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin
People and Nature, EarlyView.Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.
