We described passerine nesting in Chickasaw plum (Prunus angustifolia) as related to plum age in north-central Oklahoma during the 2007 and 2008 nesting seasons to better understand the role of plum in bird ecology. We measured properties of nests (height aboveground), nest-supporting stems (height, diameter, age) and nesting stands (age, ...

Knowledge of both the vegetation and soil seed bank of a community is necessary to understand species storage and regeneration potential. Species composition and abundance were assessed in Thomson-Fulton Sand Prairie in northwestern Illinois, U.S.A. Species richness, evenness and floristic quality were greater for the vegetation than the seed bank. ...

Agricultural fields are often overlooked as post-breeding and migratory bird habitat, even though many species use row-crop fields in the northern Great Plains. We monitored bird use, crop and non-crop vegetation characteristics and abundance, and land use around ([less than or equal to] 2.4 km) 35 8-ha Wildlife Conservation Sunflower ...

Yellow-bellied Sapsucker (Sphyrapicus vanus) foraging ecology has long been a focus of study, primarily due to their sap-foraging behavior throughout the year and speculation on how sapsuckers subsist by foraging on dormant host trees during winter. Wintering sapsucker habitat use as related to host tree selection is not clearly defined, ...

Quantification of seed arrival as an ecological flux may improve understanding of patch dynamics and variations in community structure across the landscape. Microsites favorable for germination are continually being created and destroyed in coastal ecosystems, so seed dispersal to multiple patches is essential for survival and growth. In order to ...

Reliable natural water sources often are unavailable for bats in semi-arid regions such as the Texas Panhandle. Metal stock tanks commonly are used to supply water to livestock and are used by bats as a water source. It is unknown how surface area, water level and adjacent vegetation influence use ...

We assessed the distribution of Eastern moles Scalopus aquaticus in relation to loam soils under the hypothesis that the species' Canadian distribution is limited by soil type. We also explore the relationship between mole occurrence and the amount of forest cover at a local (49 m) and landscape (305 m) ...

Survival and cause-specific mortality of eastern spotted skunks (Spilogale putorius) was assessed for a radio-monitored population in the Ouachita Mountains of westcentral Arkansas, USA. We monitored 33 eastern spotted skunks over a 23 mo period. Mean annual survival was 0.354 (0.339-0.368, 95% CI), and survival estimates were similar across age ...

Knowledge of body condition is important in predicting health and performance of large mammal populations. Therefore, we assessed body condition in black bears (Ursus amerieanus) in Rocky Mountain National Park (RMNP), Colorado, using body mass (BM), percent body fat (BF) and a body condition index (BCI) to: (1) develop a ...
MacRoberts, Michael - - 2010
The Big Thicket of Texas has been described as rich in species and a "crossroads:" a place where organisms from many different regions meet. We examine the species richness and regional affiliations of Big Thicket vertebrates. We found that the Big Thicket is neither exceptionally rich in vertebrates nor is ...
Hornbach, Daniel - - 2010
It has been hypothesized that variation in shell shape and sculpture in freshwater mussels from streams is related to hydrologic variability. Using quantitative sampling, we found smooth-shelled species were more common in upstream portions of the St. Croix River, Minnesota and Wisconsin, which has coarser substrate while species with sculptured ...

The federally endangered watercress darter (Etheostoma nuchale) is restricted to only five springs within the greater Birmingham (AL) metropolitan area. Restricted range, subpopulation isolation and threats from the urban landscape are the major factors endangering the species. The preferred habitat of E. nuchale has been described as the deeper, slow-moving ...

Lakes and reservoirs often experience sudden increases in macrophyte biomass. These changes have the potential to alter the abiotic environment in ways that affect other species. The American lotus (Nelumbo lutea) is expanding its distribution across portions of North America. N. lutea forms a dense canopy over the shallow margins ...

Cadmium (Cd) activity may vary in flooded soils but the mechanisms underlying these variations have remained conflicting and ambiguous. In this study, a continuous [N.sub.2] bubbling experiment was conducted using a red soil from the subtropical region of southern China to identify factors controlling Cd activity under reductive conditions. The ...
Rasiah, V. - - 2010
Solute import--export dynamics in groundwater (GW) systems interacting with surface-water are complex, particularly under farming systems receiving high fertiliser/pesticide inputs in high rainfall regions. We investigated whether any linkage existed between nitrate-N in: (i) leachate (LC) collected at ~1 m depth under banana (Musa) and that in GW, and (ii) ...

Surface charge characteristics were investigated using a charge fingerprinting procedure for 90 samples from 32 profiles of highly weathered Oxisols and Ultisols derived from shale/limestone, basalt, granite, local alluvium, sedimentary, and metasedimentary rocks under tropical savanna and tropical monsoonal climates in Thailand. The charge fingerprints of 5 whole soils, after ...

Many estimates have been made of the future likely extent of salinity at regional and national scales in Australia; however, there are few detailed studies of changes in temporal and spatial patterns at catchment scale. This study was conducted in the Wallatin and O' Brien catchments in the low-medium rainfall ...

There are limited datasets which cover the heavy clays found in the Murray floodplain area. To understand the processes associated with the water balance within the Koondrook-Perricoota Forest (KPF), detailed hydraulic and hydrodynamic modelling of the flood inundation patterns and overland flow in the KPF is required. Reliable and accurate ...

We present the case of a 57-year-old woman diagnosed with breast cancer and a thyroid mass that was suspicious for cancer. The breast cancer was estrogen and progesterone receptor negative, HER2/neu borderline, with a high proliferative index. Treatment of this cancer took precedence. Nine months later, a total thyroidectomy was ...
