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 < 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 < .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 < .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 < 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 < 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 < 0.05) sale price ($113.21/45.36 kg of BW;Table1). Beef-dairy cross lots sold for the second lowest (P < 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 < 0.05) sale price ($160.30/45.36 kg of BW). English-Continental cross lots sold for the second greatest (P < 0.05) sale price at $164.01/45.36 kg of BW. English-English cross lots sold for the greatest (P < 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.

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.

&lt;p&gt;This research aims to support studies related to the adaptation capacity of the Amazon region to climate change. The Belo Monte Hydroelectric Power Plant (HPP) is in the Xingu River basin, in eastern Amazonia. Deforestation coupled with changes in water bodies that occurred in the drainage area of Belo Monte HPP over the past few decades can significantly influence the hydroclimatic features and, consequently, ecosystems and energy generation in the region. In this context, we analyze the climatology and trends of climate extremes in this area. The climate information comes from daily data in grid points of 0.25&amp;#176; x 0.25&amp;#176; for the period 1980-2013, available in http://careyking.com/data-downloads/. A set of 17 climate extremes indices based on daily data of maximum temperature (TX), minimum temperature (TN), and precipitation (PRCP) was calculated through the RClimDex software, recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI). The Mann-Kendall and the Sen&amp;#8217;s Curvature tests are used to assess the statistical significance and the magnitude of the trends, respectively. The drainage area of the Belo Monte HPP is dominated by two climatic types: an equatorial climate in the north-central portion of the basin, with high temperatures and little variation throughout the year (22&amp;#176;C to 32&amp;#176;C), in addition to more frequent precipitation; and a tropical climate in the south-central sector, which experiences slightly more pronounced temperature variations throughout the year (20&amp;#176;C to 33&amp;#176;C) and presents a more defined wet and dry periods. The south-central portion of the basin exhibits the highest temperature extremes, with the highest TX and the lowest TN of the year occurring in this area, both due to the predominant days of clear skies in the austral winter, as to the advance of intense masses of polar air at this period. The diurnal temperature range is lower in the north-central sector when compared to that in the south-central region since the first has greater cloud cover and a higher frequency of precipitation. The largest annual rainfall volumes are concentrated at the north and west sides (more than 1,800 mm) and the precipitation extremes are heterogeneous across the basin. The maximum number of consecutive dry days increases from the north (10 to 20 days) to the south (90 to 100 days). The annual frequency of warm days and nights is increasing significantly in a large part of the basin with a magnitude ranging predominantly from +7 to +19 days/decade. The annual rainfall shows a predominant elevation sign of up to +200 mm/decade only in the northern part of the basin, while the remainder shows a reduction of up to -100 mm/decade. The duration of drought periods increases in the south-central sector of the basin, reaching up to +13 days/decade in some areas. The results of this study will be used in the future as an important input, together with exposure, sensibility, and local adaptation capacity, to design adaptation strategies that are more consistent with local reality and to the needs of local communities.&lt;/p&gt;

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.

Ten newly recoveredDunbaritesspecimens significantly extend the known stratigraphic range ofDunbarites.These include the first documented Midcontinent Basin records of the Missourian type speciesDunbarites rectilateralis(Miller, 1930) from north-central Oklahoma. Additional species ofDunbaritesfrom south-central Oklahoma and north-central and West Texas are described asDunbarites wewokensisn. sp. andDunbarites boardmanin. sp. AlthoughDunbaritesis an extremely rare component (~0.025 percent) of Middle and Upper Pennsylvanian ammonoid assemblages, Ruzhencev and Bogoslovskaya (1971, 1978) suggested thatDunbaritesandParashumarditesRuzhencev, 1939 be used as genozone markers for the Kasimovian [Zhigulevian] Stage (Missourian in North America). As demonstrated by this report, the range ofDunbaritesis not confined to the Kasimovian, thereby precluding its use as a Kasimovian Stage indicator.

An evaluation was made of the effectiveness elements of the pig breeding industry in Bulgaria in the period 2001-2016, through cluster analysis. The studied period was divided in 3 subperiods, each one with three similar groups (clusters). Through application of cluster analysis, the proximity of the different administration regions in the country was defined in accordance with certain indicators of the pig breeding effectiveness. It was found that in the first cluster for the period 2001-2006 fall North-Western and South-Western region. The North-Eastern and North-Central region form the second cluster. The South-Eastern and South-Central region fall mainly into the third cluster. In the first cluster for the period 2007-2011, the North-Western, South-Western and South-Central regions have a priority with the lowest number of sold animals. The North-Eastern and the North-Central region, forming a third cluster, remain with the highest effectiveness of the pig farming. After the end of 2013 an aggregation of the sector began. For the period 2012-2016, the second cluster is formed from three regions - North-Western, South-Western, and South-Central in 2013.

An exceptional flash drought during the spring and summer of 1936 led to extreme heat waves, large losses of human life and significant reductions of crop production. An analysis of historic precipitation and temperature records shows that the flash drought originated over the southeastern United States (U.S.) in April 1936. The flash drought then spread north and westward through the early summer of 1936 and possibly merged with a flash drought that had developed in the spring over the northern Plains. The timing of the flash drought was particularly ill-timed as most locations were at or entering their climatological peak for precipitation at the onset of flash drought, thus maximizing the deficits of precipitation. Thus, by early July most locations in the central and eastern U.S. were either in drought or rapidly cascading toward drought. The weeks that followed the 1st of July were some of the hottest on record in the U.S., with two major heat waves: first over the Midwest and eastern U.S. in the first half of July and then across the south-central U.S in the month of August. The combination of the flash drought and heat wave led to an agricultural disaster in the north central U.S. and one of the deadliest events in U.S. history.

Comadia redtenbacheri (Hammerschmidt) (Agave Red Worm) is the only member of the family Cossidae that has been described as a phytophagous specialist of the plant genus Agave, which is mainly distributed in México. A new extraction protocol adapted from Stewart & Via (1993) has been implemented for sequencing the COI gene from samples collected in five states of the North Central (Querétaro and Zacatecas), South Central (Estado de México) and East Central (Hidalgo and Tlaxcala) regions of México with the purpose of contributing to delineation of the species. A Maximum Likelihood (ML) tree based on these COI sequences as well as COI sequences from other Cossinae species was developed to complement the existing morphological and taxonomic approaches to delineation of this species. As expected, our Comadia samples cluster together within a monophyletic clade that includes four C. redtenbacheri sequences previously reported. This group seems to be consistent with our reconstruction, which is supported by a bootstrap value of over 99%. The closely related branches associated with the latter group include organisms known to be the plant and tree borers of the Cossinae subfamily. The COI sequences from our samples were analyzed to determine the percentage of identity among the C. redtenbacheri in a first attempt to detect differences in the sequence that matches a particular region of México.

Field surveys were conducted on 319 sites of the Western Australian grain belt in 2006 to determine the occurrence and distribution of summer fallow weed species. Sites were located across five growing season regions (north, north central, central, south central, and south) and three annual rainfall zones (high, medium, and low). A total of 51 species (or species groups) from 18 families were identified, with the large majority of species (35%) belonging to the Poaceae family. The most prevalent species found, being present at more than 10% of all sites, were wheat, “melons” (weedy watermelon and paddymelon), rigid ryegrass, capeweed, clover, mintweed, wild radish, fleabane, windmill grass, and rolypoly. Correspondence analysis revealed that the north, central, and southern regions of the grain belt could be predominately segregated according to dominant weed species occurrence; however, no segregation by rainfall zone was apparent. This study has given an overview of summer fallow weed occurrence in the Western Australian grain belt and highlights those weed species that are common and yet lack sufficient research into their ecology and management.
