Cones of lodgepole pine (Pinus contorta var. latifolia) are often serotinous, releasing their seeds from closed cones under heat from fire. Stand-replacing fires in predominantly serotinous stands can thus be expected to result in a strong regeneration response. After large-scale mortality caused by mountain pine beetle (Dendroctonus ponderosae), however, the ...

We used locations of 6 wolves (Canis lupus) in Minnesota from Global Positioning System (GPS) collars to compare day-versus-night locations to estimate territory size and location during summer. We employed both minimum convex polygon (MCP) and fixed kernel (FK) methods. We used two methods to partition GPS locations for day-versus-night ...

Survival and cause-specific mortality of female white-tailed deer (Odocoileus virginianus) have been well documented in forested and agricultural landscapes, but limited information has been collected in grassland habitats typical of the Northern Great Plains. Our objectives were to document and compare survival and cause-specific mortality of adult female white-tailed deer ...

We found dental anomalies in 36 of 249 (14.5%) cleaned skulls of eastern moles from southern Illinois and Cincinnati, Ohio. Additional teeth (supernumeration) were observed in four individuals; one specimen had a unilateral additional upper premolar, and three specimens had additional upper or lower incisors. Connation (splitting) occurred unilaterally in ...

Prairie (Microtus ochrogaster) and meadow (M. pennsylvanicus) voles are morphologically very similar species of rodents that are often found sympatrically. To assess the reliability of morphological characters typically used to differentiate between these two species, we compared the concordance of species identification based on morphological characteristics with identifications based on ...

Ruffed grouse (Bonasa umbeUus) are important game birds that depend on multiple forest age-classes of aspen (Populus spp.) for food and cover, which makes them an appropriate management indicator species for the condition of quaking aspen (Populus tremuloides) communities in the Black Hills National Forest of western South Dakota and ...

Newts of the genus Taricha have long been studied in regards to their skin toxin, tetrodotoxin (TTX). It has been shown that the TTX levels across populations of Taricha are highly variable, and this has been mostly attributed to the interaction between Taricha and their only documented predators, garter snakes ...

The effects of climate change on environments are increasingly obvious and are leading to stronger and more varied biological responses as organisms compensate. To understand better the responses of terrestrial ectotherms to climate oscillations we created a biophysical model based on the degree-days concept to predict relevant life-history events. By ...

Lake sturgeon (Acipenser fulveseens) are native within the Lake Ontario drainage basin and listed as threatened by New York State. In 1995 the New York State Department of Environmental Conservation (NYSDEC) initiated restoration management of lake sturgeon. This management included both protection of extant populations and stocking of uninhabited historic ...

Because the shovelnose sturgeon (Scaphirhynchus platorynchus) population in the Middle Mississippi River (MMR) between Cairo, IL and St. Louis, MO (RKM 0-320) appears to be declining, we must understand dietary needs to help assess its conservation status. Diet is linked to growth, condition and reproduction and reflects population state. Thus, ...

We conducted a series of studies to improve our understanding of pistolgrip life history and distribution in Minnesota and Wisconsin. In the St. Croix River, where this species is relatively abundant, we studied animals biweekly from May-Nov. 1997, Apr.-Oct. 1998 and nearly biweekly during May-Jul. 2004-2007 and observed gravid females ...
