Antipredator Blood-Squirting Defense In Horned Lizards (Phrynosoma): Chemical Isolation Of Plasma Component(S), Pogonomyrmex Ant Dietary Origin, And Evolution, Wade C. Sherbrooke, Bruce A. Kimball

United States Department of Agriculture Wildlife Services: Staff Publications

North American horned lizards of the genus Phrynosoma are largely myrmecophagous and squirt systemic blood from circumocular sinuses during encounters with certain mammalian predators. The predators react with distinct revulsion. Using bioassay-guided fractionation of blood plasma, we endeavored to identify the source and characteristics of the active chemical compound(s) responsible for this negative oral response. Our results of coyote bioassays and a series of novel mouse bioassay experiments were largely concordant. The active compound(s) was likely plasma-borne with a molecular weight (mw) of between 800 and 1,600. To identify the source of the active compound(s), we noted bioassay responses …

Eradication Of Feral Swine From A Barrier Island In Florida, Usa: An Examination Of Effort And Multi-Method, Multi-Species Population Indexing, Richard M. Engeman, Eric A. Tillman, Betsy A. Evans, John C. Griffin, Garrison Grobaski, Bradley S. Smith, John Stark, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

Feral swine (Sus scrofa) were targeted for and successfully eradicated from Saint Vincent Island (SVI), a National Wildlife Refuge (NWR) along the coast of Florida’s panhandle to protect its habitats and uncharacteristically high diversity of wildlife species for barrier islands in the region, including federal and state-listed threatened and endangered species. The eradication effort was initiated in early 2015 and concluded in 2019. A total of 438 feral swine were removed from the Island, 417 by federal control experts and 21 by recreational hunters. In general, the amount of effort needed to eradicate each feral swine slowly increased …

Downed Wood Removal Effects On Survival And Site Fidelity Of Woodrats In A California Oak Woodland, Timothy J. Smyser, Michael A. Hardy, Amy J. Davis, William L. Preston, William D. Tietje

United States Department of Agriculture Wildlife Services: Staff Publications

Owing to the increasing intensity and frequency of wildfires in the western United States, the removal of woody debris (downed dead wood and snags) from fire‐prone landscapes is being evaluated for wildfire mitigation. Consequently, the study of the ecological value of coarse woody debris to sustain dependent species has become of foremost importance. From 2004–2009, we used a before‐after control‐impact (BACI) study design to assess the effects of downed wood removal on a population of big‐eared woodrats (Neotoma macrotis) in an oak woodland (Quercus spp.) in coastal‐central California, USA. Using Pollock's robust design mark‐recapture analyses (with 12 …

High Thermal Quality Rookeries Facilitate High Thermoregulatory Accuracy In Pregnant Female Rattlesnakes, Haley A. Moniz, Jack Henry Buck, Hayley L. Crowell, Scott M. Goetz, Trevor D. Ruiz, Emily N. Taylor, Scott M. Bobacks

United States Department of Agriculture Wildlife Services: Staff Publications

Temperature is a primary factor influencing organismal development, and the fluctuating daily and seasonal thermal regimes of temperate climates may challenge the ability of viviparous reptiles to optimize body temperatures during gestation. Testing how viviparous reptiles navigate highly variable thermal conditions (e.g., relatively cold nights and/or highly fluctuating temperatures) is a powerful way to understand how they use microhabitats for thermoregulatory benefits. We assessed the thermal ecology of pregnant and non-pregnant female prairie rattlesnakes (Crotalus viridis) inhabiting a high-elevation, montane shrubland in northwest Colorado throughout their short summer active season, addressing the thermal consequences of microhabitat selection with …

Characterizing Feral Swine Movement Across The Contiguous United States Using Neural Networks And Genetic Data, Rachael M. Giglio, Courtney F. Bowden, Ryan K. Brook, Antoinette J. Piaggio, Timothy J. Smyser

United States Department of Agriculture Wildlife Services: Staff Publications

Globalization has led to the frequent movement of species out of their native habitat. Some of these species become highly invasive and capable of profoundly altering invaded ecosystems. Feral swine (Sus scrofa × domesticus) are recognized as being among the most destructive invasive species, with populations established on all continents except Antarctica. Within the United States (US), feral swine are responsible for extensive crop damage, the destruction of native ecosystems, and the spread of disease. Purposeful human-mediated movement of feral swine has contributed to their rapid range expansion over the past 30 years. Patterns of deliberate introduction of …

Bayesian Integrated Species Distribution Models For Hierarchical Resource Selection By A Soaring Bird, Ryo Ogawa, Guiming Wang, L. Wes Burger, Bronson Strickland, J. Brian Davis, Fred L. Cunningham

United States Department of Agriculture Wildlife Services: Staff Publications

Migratory birds exhibit seasonal geographic range (hereafter, range) dynamics during the annual cycle. Few studies have examined how migratory birds select their habitats for range occupancy at the species level and space use at the individual level simultaneously. We hypothesized that environmental variables directly related to fitness components would affect the range occupancy probabilities of migrants, whereas environment variables related to movements and flights would affect the space use intensities of migrants. We built Bayesian integrated species distribution models (ISDMs) to evaluate the effects of climate conditions, wind conditions, and landcover compositions on the seasonal range dynamics of American white …

Raccoon Density Estimation From Camera Traps For Raccoon Rabies Management, Amy J. Davis, Wesley C. Dixon, Richard B. Chipman, Amy T. Gilbert, Jacob E. Hill, James C. Beasley, Olin E. Rhodes Jr., Guha Dharmarajan

United States Department of Agriculture Wildlife Services: Staff Publications

Density estimation for unmarked animals is particularly challenging, yet density estimates are often necessary for effective wildlife management. Raccoons (Procyon lotor) are the primary terrestrial wildlife reservoir for Lyssavirus rabies within the United States. The raccoon rabies variant (RRVV) is actively managed at landscape scales using oral rabies vaccination (ORV) within the eastern United States. To effectively manage RRVV, it is important to know the density of raccoons to appropriately scale the density of ORV baits distributed on the landscape. We compared methods to estimate raccoon densities from camera‐trap data versus more intensive capture‐mark‐recapture (CMR) estimates across 2 …

‘Within The Reach Of Everyone’: Tracing The Global Strands Of Herrman, Sternbach & Co.’S 1880s Imitation Furs, Laura Johnson

Textile Society of America: Symposium Proceedings

Long before faux furs became trendy, vegan-friendly materials, weavers and textile designers in eighteenth and nineteenth century Europe developed a range of woven goods that offered the haptic qualities of animal pelts. Surprisingly, given their popularity, little research has focused on imitation fur production and consumption at the turn of the twentieth century and its earlier roots. This paper traces the strands linking a group of textile samples donated by New York merchant H. Herrman, Sternbach & Co. in 1884 to (what is today) the Smithsonian National Museum of American History through connecting threads of global production, innovation, and consumption. …

Copyright For Imitations: Looking At The Registered Design Book Of William Stirling & Sons, Isabel Monseau

Textile Society of America: Symposium Proceedings

The design and production of printed cotton in the United Kingdom underwent great changes through the nineteenth century. However as the industry grew, many manufacturers became concerned about a perceived decline in the quality of textile design. An attempt made to regulate this industry, the Copyright of Design Act of 1842, proposed to improve the quality of British production by enabling designers and proprietors to register their textile designs and thus prohibit other firms from pirating those original designs.

Yet imitations were crucial to the development and success of Britain’s cotton printing industry. By the 1870s, up to 60% of …

Woven Life Systems, Melanie Olde

Textile Society of America: Symposium Proceedings

What is it like to be at the intersection between the natural and technological? I see plants as living cloth – can we build cloth using human-evolved technology (weaving) and natural life systems? In this practice-as-research, I take growth models from plants such as algae, then process these codes on a loom to exploring the emergence and narrative that develop.

Looms are tools and technology evolved with humans to organise systems of strands, connecting in myriad ways to form something new. Plants are systems of organised cells, dividing and branching creating functional entities. The commonalities are individual elements and rules …

A Contribution To The Preservation And Revival Of The Cabo Verdean Pano D’Obra Textiles, Maggy Fragoso

Textile Society of America: Symposium Proceedings

Textiles from Cabo Verde were highly prized for trading along the West African coast, from the second half of the 16^th century to the end of the 18^th century. They originated from the fusion of different cultural sources making their design visually distinct from the other textiles of West Africa: slave weavers were taken to Cabo Verde by the Portuguese and with their characteristic narrow strip looms, which had to be adjusted, were made to weave textiles with North African patterns and Christian references.

From the 19^th century, a marked decline in the manufacture of these historic …
