WILD TURKEY BROOD HABITAT USE IN RELATION TO PRESCRIBED BURNING AND RED‐COCKADED WOODPECKER MANAGEMENT

open access: yesWildlife Society Bulletin, 2005
: Thinning and spring burning are used in pine and pine‐hardwood forests to restore red‐cockaded woodpecker (Picoides borealis; RCW) habitat; however, concerns regarding impacts on non‐target species have arisen.

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

FACTORS INFLUENCING WILD TURKEY POULT SURVIVAL IN SOUTHCENTRAL IOWA

open access: yesWildlife Society Bulletin, 2000
: Population models indicate that small changes in poult survival can contribute to large changes in population predictions. We used a proportional‐hazards model to evaluate the influence of habitat variables and individual characteristics on eastern ...

Parental provisioning in house wrens: effects of varying brood size and consequences for offspring

open access: yes, 2014
In biparental species, conflict between the sexes is expected when optimal levels of parental care differ between males and females. We studied food provisioning in house wrens (Troglodytes aedon) to test whether male provisioning is more strongly ...

Infestation levels of Varroa destructor in local honey bees of Jordan [PDF]

open access: yes, 2008
To determine Varroa mite infestation levels in Jordan, a survey covering 180 colonies of two bee types (Apis m. syriaca and Apis m. syriaca hybrids) from six locations of 4 climatic zones was conducted during August, 8 month after the last treatment ...

Direct Consolidation of Copper–Graphene Composite by Rotary Swaging

open access: yesAdvanced Engineering Materials, EarlyView.
The applicability of the rotary swaging method for preparation of electroconductive copper–graphene composite by direct consolidation of powders is proven. The consolidated material features advantageous microstructure featuring fine grains and twins, with homogeneous distribution of graphene, primarily along the twin boundaries, which contribute to ...

Geography and History of Periodical Cicadas (Hemiptera: Cicadidae) in DuPage County, Illinois [PDF]

open access: yes, 2018
The spatial distribution of periodical cicada (Magicicada septendecim L. and M. cassini Fisher) emergence in 2007 did not match either historical locations of woodlands or the cicadas’ own geography in the 19th and early 20th centuries in DuPage County ...
