Abstract The objective was to evaluate potential factors influencing sale price of bred heifers sold through a video auction service. Descriptive characteristics of lots were obtained through a livestock video auction service. Data were available on 1,779 lots of bred heifers sold through video auctions from 2010 through 2017. Multiple regression with a backwards selection procedure was used to determine factors influencing sale price. Eleven factors were included in the original model. These were year, weight (linear and quadratic), region, breed description, weight variation, origin, frame score, flesh score, and size of lot (linear and quadratic). Size of lot (linear and quadratic) and weight (quadratic) did not affect sale price (P > 0.05) and therefore were not included in the final model. Breed description of the lots was characterized into five groups: English-English cross, English-Continental cross, Black Angus sired out of dams with no Brahman influence, Red Angus sired out of dams with no Brahman influence, and Brahman influenced. The United States was divided into five regions: West Coast, Rocky Mountain/North Central, South Central, South East, and Northeast, which was excluded from analysis due to few lots originating from this region. Lots of bred heifers sold for the lowest sale price (P < 0.05) in 2010 at $955/head (Table 1). In 2015, lots sold for the highest price (P < 0.05) compared with all other years ($2,725/head). Those lots originating from the Rocky Mountain/North Central region sold for the highest price (P < 0.05, $1,677/head). Red Angus sired lots sold for the highest price (P < 0.05, $1,711/head) compared with all other breed descriptions. There was an $85.00 increase in price for every 45.36 kg increase in weight. Understanding factors influencing sale price of bred heifers will allow producers to make more informed decisions.

Abstract The objective was to quantify effects of value-added health protocols within region on sale price of beef calf lots sold through video auctions while adjusting for all other factors that significantly influenced price. Descriptive characteristics of lots were obtained from a livestock video auction service in an electronic format. Data were available on 43,242 lots sold through video auctions from 2010 through 2018. All lot characteristics that could be accurately quantified were used to develop a multiple regression model that evaluated effects of independent factors on sale price using a backwards selection procedure. A value of P &lt; 0.05 was used to maintain a factor in the final model. A lot was categorized into one of five health programs: 1) VAC 34 or 34+, 2) VAC 45 or 45+, 3) Weaned: viral vaccinated, 4) Non-weaned: viral vaccinated, and 5) VAC 24. Calf lots originated from one of five U.S. regions: West Coast, Rocky Mountain/North Central, South Central, Southeast, and Northeast (excluded due to few lots). In the West Coast, lots qualifying for VAC 45 or 45+ and Weaned: viral vaccinated sold for similar (P = 1.00) prices ($168.71 and $168.80/45.36 kg BW, respectively), but at prices greater (P &lt; .0001) than calves administered all other health protocols within that region. Within the Southeast region, lots qualifying for VAC 45 or 45+ and Weaned: viral vaccinated sold for similar (P = .16) prices ($168.37 and $169.28/45.36 kg BW, respectively), and again at prices greater (P &lt; .0001) than calves in all other health programs. In both the North Central and South Central regions, lots meeting the requirements for VAC 45 or 45+ sold for the greatest (P &lt; 0.05) price ($175.25 and $171.80/45.36 kg BW, respectively). Differences in sale price of calves qualifying for various health protocols suggests the value of these programs perceived by buyers varies by region.

Abstract The objective was to determine the effect of beef-dairy cross breed description as compared to Holstein and beef breed descriptions on the sale price of steer calf lots sold through Superior Livestock Auction in 2020 summer video sales. Data were available on 589 lots of weaned steer calves sold via six video auctions during the summer of 2020. Steer lots from the Rocky Mountain/North Central and South Central regions were included in the analysis. All lot characteristics that could be accurately quantified or categorized were used to develop a multiple regression model that evaluated effects of independent factors on sale price using backwards selection. A value of P &lt; 0.05 was used to maintain a factor in the final model. Based upon reported breed descriptions, lots were subsequently categorized into one of five breed groups: 1) English-English cross, 2) English-Continental cross, 3) Brahman influenced, 4) Holstein, and 5) Beef-dairy cross. The mean weight of weaned steer calves was 277.5 ± 60.1 kg. Among weaned steer calf lots, Holstein lots sold for the lowest (P &lt; 0.05) sale price ($113.21/45.36 kg of BW;Table1). Beef-dairy cross lots sold for the second lowest (P &lt; 0.05) sale price ($153.07/45.36 kg of BW), but were only $15.21/45.36 kg of BW below English-English cross. Brahman-influenced lots sold for the third lowest (P &lt; 0.05) sale price ($160.30/45.36 kg of BW). English-Continental cross lots sold for the second greatest (P &lt; 0.05) sale price at $164.01/45.36 kg of BW. English-English cross lots sold for the greatest (P &lt; 0.05) sale price ($168.38/45.36 kg of BW) compared with all other breed descriptions. Beef-dairy cross steer calves were closer in value to beef combinations than to Holstein steer calves.

Cat-associated Bartonella species, which include B. henselae, B. koehlerae, and B. clarridgeiae, can cause mild to severe illness in humans. In the present study, we evaluated 1362 serum samples obtained from domestic cats across the U.S. for seroreactivity against three species and two strain types of Bartonella associated with cats (B. henselae type 1, B. henselae type 2, B. koehlerae, and B. clarridgeiae) using an indirect immunofluorescent assay (IFA). Overall, the seroprevalence at the cutoff titer level of ≥1:64 was 23.1%. Seroreactivity was 11.1% and 3.7% at the titer level cutoff of ≥1:128 and at the cutoff of ≥1:256, respectively. The highest observation of seroreactivity occurred in the East South-Central, South Atlantic, West North-Central, and West South-Central regions. The lowest seroreactivity was detected in the East North-Central, Middle Atlantic, Mountain, New England, and Pacific regions. We observed reactivity against all four Bartonella spp. antigens in samples from eight out of the nine U.S. geographic regions.

Plant Hardiness

Landscape roses (Rosa sp.) are popular flowering shrubs. Consumers are less willing or able to maintain landscape beds than in years past and require plants that are not only attractive, but well-adapted to regional climatic conditions, soil types, and disease and pest pressures. Marketing and distribution of rose cultivars occurs on a national level; therefore, it is difficult for U.S. consumers in the U.S. Department of Agriculture (USDA) Plant Hardiness Zones 3 to 5 to identify well-adapted, cold-hardy cultivars. Identifying suitable cultivars that have strong genetic resistance to pests and disease and that will tolerate temperature extremes without winter protection in the USDA Plant Hardiness Zones 3 to 5 is of tremendous value to consumers and retailers in northern states. Twenty landscape rose cultivars, primarily developed in north-central North America, were evaluated at five locations in the United States (three in the north-central United States, one in the central United States, and one in the south-central United States) using the low-input, multiyear Earth-Kind® methodology. Six roses had ≥75% plant survival at the end of the study and were in the top 50% of performers for overall mean horticultural rating at each of the three north-central U.S. sites: ‘Lena’, ‘Frontenac’, ‘Ole’, ‘Polar Joy’, ‘Sunrise Sunset’, and ‘Sven’. Five of these six roses met the same criteria at the central United States (exception ‘Lena’) and the south-central United States (exception ‘Polar Joy’) sites. Cultivar, rating time, and their interaction were highly significant, and block effects were not significant for horticultural rating for all single-site analyses of variance. Significant positive correlations were found between sites for flower number, flower diameter, and overall horticultural rating. Significant negative correlations were found between flower number and diameter within each site and also between black spot (Diplocarpon rosae) lesion size from a previous study and overall horticultural rating for three of the five sites. Cane survival ratings were not significantly correlated with overall horticultural rating, suggesting some cultivars can experience severe winter cane dieback, yet recover and perform well. Data from this study benefit multiple stakeholders, including nurseries, landscapers, and consumers, with evidence-based regional cultivar recommendations and breeders desiring to identify regionally adapted parents.

Abstract The 241 largest snowstorms over the eastern two-thirds of the United States during 1950–2000 exhibited considerable temporal variability ranging from 1 storm in three winters to 10 storms in 1993/94. The peak decadal frequency was 55 storms (1950s), and the minimum was 45 storms (1970s and 1980s). The east–north-central region experienced the greatest number of large snowstorms (148) followed by the west–north-central (136) and central (133) regions. Regional trends were different. Assessment of surface cyclone tracks associated with the large snowstorms identified three primary tracks: one was located from the leeward side of the south-central Rocky Mountains east-northeast toward the Great Lakes; a second was from the lower Mississippi River basin northeastward toward the Great Lakes; and a third was along the coastal mid-Atlantic region northeast toward Maine. Temporal differences in the frequency of certain surface cyclone tracks were related to the decadal trends in regional large snowstorm occurrence. The minimum surface pressure associated with these storms ranged from 959 to 1013 hPa with more than 67% of all storms having a minimum surface pressure between 980 and 999 hPa. The average orthogonal distance from the storm track to the heavy snow region was 201 km. The average rate of cyclone movement ranged from less than 483 to more than 1930 km day−1, with more than 57% of storms moving between 805 and 1287 km day−1.

Kinosternon Subrubrum

AbstractKinosternonSpix, 1824, was widespread in xeric to savanna associated paleowetlands across North America during the middle–late Miocene and steadily diversified following its first occurrences in the Hemingfordian. In the middle Miocene,Kinosternon rinconn. sp. occurred in the late Barstovian Cerro Conejo Formation of north central New Mexico, perhaps concurrently withKinosternon pojoaqueBourque 2012a from the Tesuque Formation. Subsequent late Miocene kinosternine fossils indicate that at least three potentially contemporaneous species existed throughout the Clarendonian. These areKinosternon pannekollopsn. sp., from the Ogallala Formation of northern Texas;Kinosternon wakeeniense, n. sp., from the Ogallala Formation of northwestern Kansas and Ash Hollow Formation of south-central Nebraska; andKinosternon notolophusn. sp., from the Alachua and Statenville formations of northern Florida.Kinosternon rinconis phylogenetically nested between theKinosternon flavescens(Agassiz, 1857) group (=PlatythyraAgassiz, 1857) and more derivedKinosternonincluding theKinosternon subrubrum(Lacépède, 1788) group (=ThyrosternumAgassiz, 1857).Kinosternon pannekollopsis recovered on the stem of theK.subrubrumgroup and is the oldest and largest member of that lineage.Kinosternon notolophusis readily differentiated from other MioceneKinosternonin possessing a distinct dorsomedial keel on the nuchal and faint dorsolateral costal carination. TheK.subrubrumgroup probably originated in the late Miocene savannas of the Great Plains and dispersed eastward via the Gulf Coastal Plain. An unnamed kinosternine taxon existed in the coastal plains of the eastern and southeastern United States during the Middle Miocene Climatic Optimum (with fossils from ~18 to 15 Ma), and disappeared from the region coincident with the end of that megathermal event.

ABSTRACT Objectives: To compare the risk of mild cognitive impairment (MCI) among a wide range of ethnoracial groups in the US. Design: Non-probabilistic longitudinal clinical research. Setting: Participants enrolling into the National Alzheimer’s Coordinating Center Unified Data Set recruited via multiple approaches including clinician referral, self-referral by patients or family members, or active recruitment through community organizations. Participants: Cognitively normal individuals 55 and older at the initial visit, who reported race and ethnicity information, with at least two visits between September 2005 and November 2018. Measurements: Ethnoracial information was self-reported and grouped into non-Latino Whites, Asian Americans, Native Americans, African Americans (AAs), and individuals simultaneously identifying as AAs and another minority race (AA+), as well as Latinos of Caribbean, Mexican, and Central/South American origin. MCI was evaluated clinically following standard criteria. Four competing risk analysis models were used to calculate MCI risk adjusting for risk of death, including an unadjusted model, and models adjusting for non-modifiable and modifiable risk factors. Results: After controlling for sex and age at initial visit, subhazard ratios of MCI were statistically higher than non-Latino Whites among Native Americans (1.73), Caribbean Latinos (1.80), and Central/South American Latinos (1.55). Subhazard ratios were higher among AA+ compared to non-Latino Whites only in the model controlling for all risk factors (1.40). Conclusion: Compared to non-Latino Whites, MCI risk was higher among Caribbean and South/Central American Latinos as well as Native Americans and AA+. The factors explaining the differential MCI risk among ethnoracial groups are not clear and warrant future research.
