Stress and fish reproduction: The roles of allostasis and hormesis
C.B. Schreck
2010, General and Comparative Endocrinology (165) 549-556
This paper is a review of the effects of stress on reproduction in fishes. I hope to further the development of the concepts of allostasis and hormesis as relevant to understanding reproduction in general and in fish in particular. The main contentions I derive in this review are the following:...

Long-term reductions in anthropogenic nutrients link to improvements in Chesapeake Bay habitat
H. Ruhl, N. B. Rybicki
2010, Proceedings of the National Academy of Sciences of the United States of America (107) 16566-16570
Great effort continues to focus on ecosystem restoration and reduction of nutrient inputs thought to be responsible, in part, for declines in estuary habitats worldwide. The ability of environmental policy to address restoration is limited, in part, by uncertainty in the relationships between costly restoration and benefits. Here, we present...

Daniel J. Johnson, Albert A. Eggers, Marco Bagnardi, Maurizio Battaglia, Michael P. Poland, Asta Miklius
2010, Geology (38) 1139-1142
Using microgravity data collected at Kīlauea Volcano, Hawai‘i (United States), between November 1975 and January 2008, we document significant mass increase beneath the east margin of Halema‘uma‘u Crater, within Kīlauea's summit caldera. Surprisingly, there was no sustained uplift accompanying the mass accumulation. We propose that the positive gravity residual in...

The No. 12 Coal (Late Permian) in the Songzao Coalfield, Chongqing, southwestern China, is characteristically high in pyrite and some trace elements. It is uniquely deposited directly above mafic tuff beds. Samples of coal and tuffs have been studied for their mineralogy and geochemistry using inductively coupled plasma-mass spectrometry, X-ray...
Contrasting activity patterns of sympatric and allopatric black and grizzly bears
C.C. Schwartz, S.L. Cain, S. Podruzny, S. Cherry, L. Frattaroli
2010, Journal of Wildlife Management (74) 1628-1638
The distribution of grizzly (Ursus arctos) and American black bears (U. americanus) overlaps in western North America. Few studies have detailed activity patterns where the species are sympatric and no studies contrasted patterns where populations are both sympatric and allopatric. We contrasted activity patterns for sympatric black and grizzly bears...

2010, Ecology (91) 2883-2897
The polar bear (Ursus maritimus) depends on sea ice for feeding, breeding, and movement. Significant reductions in Arctic sea ice are forecast to continue because of climate warming. We evaluated the impacts of climate change on polar bears in the southern Beaufort Sea by means of a demographic analysis, combining...
Occurrence of avian Plasmodium and West Nile virus in culex species in Wisconsin
T. Hughes, P. Irwin, E. Hofmeister, S.M. Paskewitz
2010, Journal of the American Mosquito Control Association (26) 24-31
The occurrence of multiple pathogens in mosquitoes and birds could affect the dynamics of disease transmission. We collected adult Culex pipiens and Cx. restuans (Cx. pipiens/restuans hereafter) from sites in Wisconsin and tested them for West Nile virus (WNV) and for avian malaria (Plasmodium). Gravid Cx. pipiens/restuans were tested for...

Restoration and revegetation associated with control of saltcedar and Russian olive: Chapter 7
Patrick B. Shafroth, David M. Merritt, Vanessa B. Beauchamp, Kenneth D. Lair
2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
Rationales for controlling or eliminating saltcedar and Russian olive from sites, river reaches, or entire streams include implicit or explicit assumptions that natural recovery or applied restoration of native plant communities will follow exotic plant removal (McDaniel and Taylor, 2003; Quimby and others, 2003). The vegetation that replaces saltcedar and...
Saltcedar and Russian olive interactions with wildlife: Chapter 4
Heather L. Bateman, Eben H. Paxton
2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
Riparian areas of flood plains typically provide a mosaic of productive habitats (Stanford and others, 2005; Latterell and others, 2006) capable of supporting many wildlife species, particularly in the arid and semiarid Western United States. The establishment of nonnative invasive plants can alter riparian habitat by inhibiting native plant recruitment...

2010, Book chapter, Saltcedar and Russian Olive Control Demonstration Act Science Assessment (Scientific Investigations Report 2009–5247)
This chapter discusses the components of the water budget for a riparian system containing large stands of saltcedar or Russian olive—that is, how water is used by the plant community and how that use affects both streamflow volume and groundwater levels. The relation of water availability to the hydrologic cycle...
