Fimicolous Histeridae coleoptera in Campo Grande, MS, Brazil. (1/31)

Fecal masses recently excreted and/or almost dry were collected weekly in a pasture of Brachiaria decumbens Stapf, from May 1990 to April 1992. The feces were conditioned in 15-liter opaque plastic buckets, containing lateral and top openings, where flasks were fastened for capturing Histeridae beetles present in these masses. Three thousand two hundred ninety-nine specimens were collected belonging to 11 species in the Genus: Phelister, Hister, Euspilotus, Acritus, and Xerosaprinus. The most frequent, constant, and abundant species were Phelister sp. nr. carinifrons and P. haemorrhous.  (+info)

Symmetric pollen mitosis I and suppression of pollen mitosis II prevent pollen development in Brachiaria jubata (Gramineae). (2/31)

Microsporogenesis and pollen development were analyzed in a tetraploid (2n = 4x = 36) accession of the forage grass Brachiaria jubata (BRA 007820) from the Embrapa Beef Cattle Brachiaria collection that showed partial male sterility. Microsporocytes and pollen grains were prepared by squashing and staining with 0.5% propionic carmine. The meiotic process was typical of polyploids, with precocious chromosome migration to the poles and laggards in both meiosis I and II, resulting in tetrads with micronuclei in some microspores. After callose dissolution, microspores were released into the anther locule and appeared to be normal. Although each microspore initiated its differentiation into a pollen grain, in 11.1% of them nucleus polarization was not observed, i.e., pollen mitosis I was symmetric and the typical hemispherical cell plate was not detected. After a central cytokinesis, two equal-sized cells showing equal chromatin condensation and the same nuclear shape and size were formed. Generative cells and vegetative cells could not be distinguished. These cells did not undergo the second pollen mitosis and after completion of pollen wall synthesis each gave rise to a sterile and uninucleate pollen grain. The frequency of abnormal pollen mitosis varied among flowers and also among inflorescences. All plants were equally affected. The absence of fertile sperm cells in a considerable amount of pollen grains in this accession of B. jubata may compromise its use in breeding and could explain, at least in part, why seed production is low when compared with the amount of flowers per raceme.  (+info)

Effect of the tropical grass Brachiaria brizantha (Hochst. ex A. Rich.) Stapf on microbial population and activity in petroleum-contaminated soil. (3/31)

The effect of the tropical pasture grass Brachiaria brizantha on numbers of bacteria, fungi and degraders of alkanes, aromatics, cycloalkanes and crude oil in petroleum hydrocarbon contaminated and uncontaminated savannah soil was evaluated. Substrate induced soil respiration and soil pH were compared between planted and unplanted soil. B. brizantha had a mostly increasing effect on microbial numbers. As an exception, growth of bacteria was not or negatively affected. Microbial respiration and pH were always lower in planted than in unplanted soil. Low pH may result from enhanced oil degradation in planted soil leading to an accumulation of organic acids. A comparable stimulation of crude oil degraders and fungi in planted soil points to the importance of fungi. Since they tolerate lower pH values than bacteria, they are considered to play a central role in oil degradation. Given that the enhancement of crude oil degradation under the influence of B. brizantha could not clearly be correlated to microbial numbers and activity, other factors like oxygen availability, plant enzymes and synergistic degradation by microbial consortia have to be considered.  (+info)

Evidence of allopolyploidy in Brachiaria brizantha (Poaceae: Paniceae) through chromosome arrangement at metaphase plate during microsporogenesis. (4/31)

In the hexaploid (2n = 6x = 54) accession B176 of Brachiaria brizantha, one cytological characteristic differentiated it from the other accessions previously analyzed with the same ploidy level. Nearly 40% of meiocytes displayed the chromosome set arranged at two metaphase plates at the poles of the cell, close to the membrane. In these cells, both metaphase plates were arranged in an angle to form a typical tripolar spindle. Therefore, cells did not show normal chromosome segregation at anaphase I. Only nine univalent chromosomes migrated from each plate to the opposite pole with the remainder staying immobile on the plate. As a result of such spindle orientation and chromosome behavior, trinucleate telophases I were recorded. After telophase, cytokinesis eliminated the small nuclei into a microcyte. The second division proceeded normally, with the presence of microcytes in all phases. The origin of such an abnormality was explained on the hexaploid level of the accession which could have resulted by chromosome doubling of a triploid derived from species that did not display the same behavior for spindle organization. The high percentage of meiotic abnormalities recorded in this accession compromises fertility and renders it inadequate for the breeding program.  (+info)

Microsporogenesis in Brachiaria dictyoneura (Fig. & De Not.) Stapf (Poaceae: Paniceae). (5/31)

Microsporogenesis was analyzed in five accessions of Brachiaria dictyoneura presenting x = 6 as the basic chromosome number. All accessions were tetraploid (2n = 4x = 24) with chromosome pairing in bi-, tri-, and quadrivalents. The recorded meiotic abnormalities were those typical of polyploids, including precocious chromosome migration to the poles, laggard chromosomes, and micronucleus formation. The frequency of these abnormalities, however, was lower than those reported for other polyploid accessions previously analyzed for other Brachiaria species. Cell fusion and absence of cytokinesis were also recorded in some accessions, leading to restitutional nucleus formation in some cells. Genetically unbalanced microspores, binucleate, and 2n microspores were found among normal meiotic products as results from these abnormalities. The limitation in using these accessions as pollen donor in interspecific crosses with sexual species with x = 7 or x = 9 in breeding programs is discussed.  (+info)

Evidence of programmed cell death during microsporogenesis in an interspecific Brachiaria (Poaceae: Panicoideae: Paniceae) hybrid. (6/31)

Morphological changes have been investigated during plant programmed cell death (PCD) in the last few years due to the new interest in a possible apoptotic-like phenomenon existing in plants. Although PCD has been reported in several tissues and specialized cells in plants, there have been few reports of its occurrence during microsporogenesis. The present study reports a typical process of PCD during meiosis in an interspecific Brachiaria hybrid leading to male sterility. In this hybrid, some inflorescences initiated meiosis but it was arrested in zygotene/pachytene. From this stage, meiocytes underwent a severe alteration in shape showing substantial membrane blebbing; the cytoplasm became denser at the periphery; the cell nucleus entered a progressive stage of chromatin disintegration, and then the nucleolus disintegrated, and the cytoplasm condensed and shrunk. The oldest flowers of the raceme showed only the callose wall in the anthers showing obvious signs of complete sterility.  (+info)

Abnormal cytokinesis in microsporogenesis of Brachiaria humidicola (Poaceae: Paniceae). (7/31)

Microsporogenesis was evaluated in the Brachiaria humidicola collection of the Embrapa Beef Cattle Center, represented by 60 accessions. One accession (H121) presented an abnormal pattern of cytokinesis that had never been reported in this genus. Among 900 meiocytes analyzed in the first division, 10.7% underwent precocious and multiple cytokinesis in metaphase I, fractionating the genome and the cytoplasm into two or more parts. The expected cytokinesis after telophase I did not occur. The abnormal meiocytes from the first division entered the second division but the second cytokinesis after telophase II was also abnormal. Among the 857 meiocytes analyzed in the second division, 10.9% presented abnormal, incomplete or total absence of cytokinesis. Dyads and binucleated microspores were recorded among the meiotic products. The use of this accession in the Embrapa breeding program is compromised.  (+info)

Microsporogenesis in sexual Brachiaria hybrids (Poaceae). (8/31)

Three sexual interspecific hybrids of Brachiaria (HBGC076, HBGC009, and HBGC014) resulting from crosses between B. ruziziensis (female genitor) and B. decumbens and B. brizantha (male genitors) produced by Embrapa Beef Cattle in the 1980s were cytologically analyzed by conventional methods for meiotic studies. The cytogenetic analysis showed the occurrence of common meiotic abnormalities among them. The most frequent abnormalities were those related to irregular chromosome segregation due to polyploidy. Other abnormalities, such as chromosome stickiness, absence of cytokinesis, irregular cytokinesis, abnormal spindle orientation, and abnormal nucleolus disintegration, were found in the three hybrids, while, chromosome disintegration was detected only in HBGC014. All the abnormalities, except for abnormal nucleolus disintegration, can cause unbalanced gamete formation, leading to pollen sterility. Multivalent chromosome association at diakinesis revealed genome affinity between the two parental species in the hybrids, suggesting some possibility for gene introgression. Presently, the Brachiaria breeding program has the objective of releasing, primarily, apomictic hybrids as new cultivars since they do not segregate but preserve the genetic makeup indefinitely. Besides, they result in homogeneous pastures which are easier to manage. The sexual hybrids, however, are paramount in the breeding program: they work as 'bridges' to introgress traits of interest into the apomictic genotypes. The cytogenetic analyses of these three hybrids substantiate their maintenance in the breeding program due to low frequency of meiotic abnormalities, complemented by interesting agronomic traits. They may be used in crosses to generate new cultivars in the future.  (+info)

The apomictic reproductive mode of Brachiaria (syn. Urochloa) forage species allows breeders to faithfully propagate heterozygous genotypes through seed over multiple generations. In Brachiaria, reproductive mode segregates as single dominant locus, the apospory-specific genomic region (ASGR). The AGSR has been mapped to an area of reduced recombination on Brachiaria decumbens chromosome 5. A primer pair designed within ASGR-BABY BOOM-like (BBML), the candidate gene for the parthenogenesis component of apomixis in Pennisetum squamulatum, was diagnostic for reproductive mode in the closely related species B. ruziziensis, B. brizantha, and B. decumbens. In this study, we used a mapping population of the distantly related commercial species B. humidicola to map the ASGR and test for conservation of ASGR-BBML sequences across Brachiaria species. Dense genetic maps were constructed for the maternal and paternal genomes of a hexaploid (2n = 6x = 36) B. humidicola F1 mapping population (n = 102) using

INTRODUCTION Most plants have the ability to adjust their morphological and physiological characteristics in response to exposure to unfavorable light environment (Pearcy, 1999). However, depending on their acclimation capacity, the efficiency of these adjustments can vary considerably among species. This acclimation capacity is key in determining their competitive potential in that specific environment (Gloser & Gloser, 1996; Wong & Stur, 1996; DiasFilho, 1999; Nandal et al., 1999). Forage grasses in tropical pastures can be subjected to a considerable reduction in the amount of light they receive (Humphreys, 1991). This condition is usually a consequence of the deliberate introduction of tree species, or the invasion of woody weeds in active pasture areas, the establishment of pastures in plantations, or even the diurnal or seasonal reduction in the amount of sunshine due to cloud cover. In Brazil, shading of pasture areas by plantation agriculture has the potential to become more prevalent, ...

INFLUENCE OF UN-IONIZED AMMONIA AND INORGANIC CARBON ON BIOLOGICAL NITRIFICATION Albert J. Hill, Graduate Student Ronald D. Neufeld, Associate Professor Civil Engineering Department University of Pittsburgh Pittsburgh, Pennsylvania 15261 INTRODUCTION The overall objective of this research is to conduct basic studies into possible causes of biological nitrification process instability as currently observed in steel industry wastewaters, and in the longer term to propose rational and pragmatic process and/or operational alternatives for the biological oxidation of ammonia. The approach taken in this research is to quantify the influences of key reproducable parameters on the biokinetics of nitrification. The parameters considered are alkalinity and free (or un-ionized) ammonia. Coking is the heating of bituminous coal in the absence of air; gases are given off and a residue remains in the oven. The residue is coke, a major ingredient in the blast furnace manufacturing of pig iron. In a by-products ...

Pantea, Environmental Engineer Eli Lilly and Company Tippecanoe Laboratories Lafayette, Indiana INTRODUCTION A biological nitrification wastewater treatment plant has been designed and constructed to treat a wastewater from fermentation processes at Tippecanoe Laboratories, located in Lafayette, Indiana. The driving force in the project was the need to remove ammonia in this particular wastestream. There are three wastestreams from the plantsite, all combining at the outfall to total 12 MGD. The major ammonia load is from the fermentation production wastestream; hence, the ammonia reduction was targeted for the fermentation wastewater treatment plant. The current NPDES permit has a 2000 pounds/day daily average limit of ammonia at the outfall. The proposed limit in the permit, expected to be issued late in 1993, is ...

Cattle production on Brachiaria pastures is a primary use of cleared forestland in the western Brazilian Amazon. About 6.8 million hectares in the States of Acre and Rondônia have been deforested, where 75% of land is now grazed (IBGE, 1998). The principal pasture species are B. brizantha and B. decumbens with the latter in decline from spittlebug susceptibility (Deois incompleta; Gonçalves et al., 1996). The general pattern of pasture establishment in the Amazon basin includes felling and burning forest biomass, planting annual crops for one to three years (especially on small farms), and then seeding to grasses. The conversion of tropical forest to pasture, the effects of that process on soil properties, and pasture degradation outcomes have been studied in the eastern Amazon region ( Serrao et al., 1978; Reiners et al., 1994; Sanchez and Salinas, 1981; Buschbacher et al., 1987; Moraes et al., 1996) but not in the remote western region.

The ability to distinguish transgenic cells of untransformed cell mass is a key step for the production of transgenic plants. Thus, the use of selection marker genes for identification of genetically modified plants is necessary. The aim of this study was to determine the optimal concentration of four selective agents (kanamycin, hygromycin, phosphinothricin and mannose) to inhibit in vitro growth of Urochloa brizantha cv. Marandu calli. Embryogenic calli were obtained from mature seeds inoculated in MS medium supplemented with 30 g/L sucrose, 3 mg/L 2,4-dichlorophenoxy acetic acid (2,4-D) and 300 mg/L hydrolysate casein and their growth rate was monitored for 74 days by measuring calli fresh weight. It was demonstrated that U. brizantha calli are more sensitive to low concentrations of hygromycin than kanamycin (25 and 50 mg/L, respectively). For the herbicide phosphinothricin, 5 mg/L was enough to prevent the calli growth, but allowed escape. Mannose should be used as the only carbon source on the
During the 1999-2000 season, researchers in Colombia discovered populations of a grassland spittlebug, Prosapia simulans, a pest previously known to occur only from Mexico to Panama. Grassland spittlebugs are a widely distributed complex of species ranging from Ontario, Canada to Panama that are damaging pests of graminoid crops, particularly sugarcane and forage grasses (ie, Brachiaria decumbens or "signal grass"). This report is the first documentation of this species, as well as the genus Prosapia, in South America.. Also in 1999, the sugarcane aphid, Melanaphis sacchari, was collected in Louisiana, a new distribution record for this species in the continental U.S. Further surveys demonstrated that M. sacchari had already spread throughout most of the sugarcane producing areas in Louisiana. The aphid was initially found in the U.S. during 1977 on sugarcane in Florida. Besides sugarcane, this pest is known to infest other grasses, including species in the genera Sorghum, Oryza, and Panicum, ...

Vasquez, J.; Perez, J.; Melendez, F., 1979: Effect of nitrogen, frequency and height of cutting on carbohydrate reserves and production of dry matter from Para grass (Brachiaria mutica)
An outbreak of hepatogenous photosensitization is reported in a flock of 28 sheep grazing Brachiaria decumbens in Mato Grosso do Sul State, Central-Western Brazil. Seven lambs and an adult sheep were affected and 6 of them died. Two surviving affected lambs and one lamb without clinical signs had increased serum values of gamma glutamyltransferase, bilirubin, and cholesterol. In two adult unaffected sheep those parameters were within normal values. An adult sheep submitted to necropsy presented moderate body condition, unilateral corneal opacity, drying of the muzzle, moderate jaundice, increased lobular pattern of the liver, and a distended gallbladder. Histological lesions were epithelial degeneration, necrosis, and hyperplasia of small bile ducts. Mild amounts of foamy macrophages were observed, mainly in the centroacinar zone. Diffuse swelling and vacuolation were observed in hepatocytes. Crystal negative images were found within bile ducts, foamy macrophages, and the lumen of some renal ...

Aristida chaseae is a rare species of grass known by the common name Chases threeawn. It is endemic to Puerto Rico, where it is known from two locations in the Cabo Rojo National Wildlife Refuge and the Sierra Bermeja.[1] It is a federally listed endangered species of the United States. It cannot compete with introduced species of grasses, such as Brachiaria subquadripara, which are invading its habitat.[1]. This is a perennial grass producing a tuft of stems up to half a meter high or a bit taller. Plants occurring in the deep soils of Cabo Rojo tend to be more robust than those growing in the poorer soils of the Sierra Bermeja.[2] Cabo Rojo plants occur in coastal grassland habitat, and those in the Sierra grow in acidic clay soils with many rocky outcrops.[2] Development of the Sierra Bermeja is a potential threat for the grass and many other endemic plant species.[2]. ...

The Hampton Roads Sanitation District (HRSD) operates thirteen treatment plants in the eastern Virginia area with a combined capacity of 231 million gallons per day (mgd). The Nansemond Treatment Plant (NTP) is one of the larger facilities, and is designed to treat 30 mgd using a 3-stage Virginia Initiative Process (VIP) biological nutrient removal (BNR) process. The majority of the influent is domestic, but there is also a large industrial contribution, particularly from a hog processing facility, landfill leachate, and significant loads from septage and grease deliveries (Bilyk et al, 2008). NTP is currently being upgraded to a 5-stage Bardenpho process to achieve improved total nitrogen (TN) removal. For several years starting in about 2001, NTP has experienced continuous and sporadic nitrification upsets that cannot be explained by plant operations events. Sporadic nitrification upsets are characterized by sharp increases in effluent ammonia and nitrite with decreases in nitrate ...
The State of Maryland, acting to improve the health of Chesapeake Bay under the Chesapeake Bay Program, has initiated the Enhanced Nutrient Removal (ENR) Program to reduce the discharge of nutrients to Chesapeake Bay. The Patapsco Wastewater Treatment Plant (Patapsco), located in the City of Baltimore, Maryland, is currently in the planning and design stages of a nutrient removal project that includes the upgrade of the facility from secondary treatment limits with no nitrogen removal technology to ENR levels (3 mg/L total nitrogen and 0.3 mg/L total phosphorus, annual average). However, previous work at the facility indicated that a portion of the influent is frequently inhibitory to nitrification, causing complete failure in the previous attempts to nitrify the wastewater ...
The MBF shows to be very reliable for hosting aerated biological processes. Furthermore maintenance and operation attendance is low, which makes it particularly suitable for smaller works, which tend to be unattended. A thin biofilm on top of the sand grains is developed within the bioreactor. This enables a stable nitrifying population to be maintained in the reactor under varying process conditions. Shock loadings are therefore handled effectively. Furthermore the continuous sand circulation allows the biomass to nitrify even under low loading conditions.. ...

Due to its continental dimensions, Brazil is one of the countries that has in its soil and climate diversity a great potential for viticulture. It is possible to obtain high quality wines, combining the characteristics of each area to high production technology. Embrapa Uva e Vinho, located in Bento Gonçalves, in Rio Grande do Sul, follows since 2004 the development of the new hubs producing fine wines in Brazil. That happens in different ways. One of the main points is the characterization of the regions, from the soil and climate point of view. Establishment of protocols for grape ripening control, by means of previous marking of plants. The decision about the harvest date and the definition of the most appropriate vinification process. All those factors together, ...

Although the spittle of these creatures servers as a formidable weapon in combat, the Spitters original purpose for the hive seems to be entirely different. The Spitter can obviously produce quite different kinds of spittle. The most often observed feature is the ability to use some kind of gooey spittle that can trap smaller opponents and that becomes hard and resilient when drying up. It is often used to repair hive structures on the fly or even to erect some structures such as barricades when used by larger groups of Spitters. Since it takes some time to harden, it is only annoying and disgusting for bigger opponents such as humans, for this reason this kind of spittle is rarely seen in combat. In battle, they rather use their corrosive spittle. The use of this kind of spittle outside of war is somewhat up to speculations. It seems possible that it is used to dissolve hive structures that are no longer needed. The dissolved structures can be devoured by several of the hive creatures and later ...
Having spent more than a decade identifying and cloning AltSB, Jura and Leon have recently turned their attention to identifying and cloning the genes responsible for phosphorus efficiency in sorghum. Luckily, they werent starting from scratch this time, as another GCP project on the other side of the world was well on the way to identifying a phosphorus-efficiency gene in rice.. Led by Matthias Wissuwa at JIRCAS and Sigrid Heuer at IRRI, the Asian base GCP project had identified a gene locus, which encoded a particular protein kinase that allowed varieties with this gene to grow successfully in low-phosphorous conditions. They termed the region of the rice genome where this gene resides as phosphorus uptake 1 or Pup1 as it is commonly referred to in short.. "In phosphorus-poor soils, this protein kinase instructs the plant to grow larger, longer roots, which are able to forage through more soil to absorb and store more nutrients," explains Sigrid. "By having a larger root surface area, ...

Adult spittlebugs are 5-7 mm in length and are dull brown in colour. Nymphs vary from white to pale green in colour and have dark eyes and distinct legs. These insects overwinter as eggs on the lower leaves and stems of host plants and in the stubble of strawberry plantings. Egg hatch coincides with appearance of blossoms. Nymphs feed within a frothy mass of spittle (hence the common name), piercing plant tissue and sucking plant juices. The nymphs are often found on and between clusters of flower buds and within the crown. Nymphs mature in late June and emerge from the spittle as winged adults. There is one generation per year.. Spittlebugs are easily recognized by the mass of foam that they secrete around their bodies. One species that occurs on strawberries is the meadow spittlebug. The nymphs are white to green in colour, with dark eyes and distinct legs. The adult meadow spittlebug is bright green when it emerges but quickly turns a dull brown. It is about 5-7 mm long.. ...
Wastewater from wet lime(stone)-gypsum flue gas desulphurisation (FGD) processes in coal-fired power plants contains nitrate. Where case selective catalytic reduction (SCR) of NOx is applied the wastewater can also contain ammonia. For the removal of both nitrate and ammonia, biological processes are an attractive option. A bottle-neck for application of biological processes might be the high chloride concentration and relatively high temperature of the wastewater. Therefore research work was performed in fluid-bed reactors at pilot-plant scale for both biological nitrification and denitrification. Biological nitrification was studied up to 34 gCl−/l and nitrite was the main product formed. Biological denitrification was effective up to at least 45 gCl−/l. Both nitrate and nitrite were removed effectively. ...

The guiding recommendation for fall applications is the 50° F rule. Soil temperature at the depth of application can have a huge impact on the efficiency of the fertilizer and the effectiveness of nitrification inhibitors. Nitrifying bacteria are active until soils freeze at 32° F, but their activity is greatly reduced once soil temperature goes below 50° F. Higher temperatures also result in faster breakdown of the molecules that provide nitrification inhibition.. The 50° F rule is a good compromise between when the activity of nitrifying bacteria is low enough and there is still enough time for nitrogen applications before soils become too wet or frozen. The cooler the temperature the greater the efficiency of an inhibitor and the greater chance ammonium does not convert to nitrate.. Look for up to date soil temperatures at https://app.gisdata.mn.gov/mda-soiltemp/. Use these values only as a reference. Since soil temperatures can be influenced by a number of factors, like residue cover, ...
Ammonium attenuation in subsoils and groundwater is predominantly due to cation exchange and/or nitrification (biological oxidation) processes. These processes have been little studied in UK formations and this relative lack of information can result in reduced consistency and robustness in the assessment of risks posed by ammonium contamination arising from landfills, effluent soakaways, contaminated sites and other sources. A review of ammonium fate and transport in the subsurface has been completed and guidance developed on the key processes that contribute to attenuation. The amount of relevant literature is small but sufficient to provide indicative ranges of partition coefficients and biological nitrification rates for ammonium in UK subsoils and aquifers. Ammonium attenuation was found to be highly sensitive to the clay mineralogy and pore size of the strata, the availability of oxygen and the chemical composition of the contaminated fluid. The values derived may have application in the ...
With an aim to contribute to our knowledge of distribution patterns of Paspalum species, this study examines the distribution of the species that occur in Pernambuco. In order to do this, extensive reviews of the literature, of specimens deposited in several herbaria, and of databases available on the Internet, in addition to collections made in the State of Pernambuco were performed. The 31 species analyzed were classifi ed into two distribution patterns: broad, with 29 species and restricted, with two species. The species with restricted distribution are found in the Northeast region of Brazil, with one endemic to the semi-arid domain and the other until now only recorded from the Atlantic coast of Brazil. The broad distribution pattern can be subdivided into two groups, continuous and disjunct, which can be subsequently classifi ed into three subgroups: American, Central-South American, and South American. The importance of this analysis for a better understanding of flora of Pernambuco ...

Brazil - The Brazilian Agricultural Research Corporation, Embrapa, which is linked to the Brazilian Ministry of Agriculture, Livestock and Supply, has created two clones from a Junqueira cow. The Junqueira is an endangered species. It is estimated that there are less than 100 of them on Brazilian territory.. The cloned calves were created using cells from the ear of a nine year old cow. The first clone, called "Porã" was born on April 10, weighing 55 lbs. (25 kg), after 292 days of gestation. "Potira", the second cloned calf was born, weighing 64 lbs. (29 kg), on April 24, after a 290-day gestation period. The clones are healthy, and are being monitored by Embrapa researchers.. The breed Junqueira is popular for meat and milk production. In addition, they are used as work animals. The first cows were brought to Brazil by Spanish and Portuguese settlers. The breed developed inside São Paulo, during the 18th and 19th centuries. The cows long horns are their most prominent identifying ...
Balanced reciprocal chromosomal translocations (RCTs) are the ones of the most common structural aberrations in the population, with an incidence of 1:625. RCT carriers usually do not demonstrate changes in phenotype, except when the translocation results in gene interruption. However, these people are at risk of production of unbalanced gametes during meiosis, as a result of various forms of chromosome segregation. This may cause infertility, non-implantation of the embryo, shorter embryo or foetus survival, as well as congenital defects and developmental disorders in children after birth. The increasing popularity of cytogenetic molecular techniques, such as microarray-based CGH (aCGH), contributed to the improved detection of chromosomal abnormalities in patients with intellectual disability, however, these modern techniques do not allow the identification of the balanced in potential carriers. Therefore, classical chromosome analysis with GTG technique still plays an important role in the

Spit on the contrary appears much more simple. Two opposing screens show the artist s face. He spits and spittle hits his face and runs down slowly. The opposite position of the images evokes the impression as though he spat into his own face. Spitting in someone s face is an act of humiliation born by fury or contempt. Spitting oneself consequently appears as a form of self-contempt which, as a psychological phenomenon, largely remains invisible. Also, the splitting of the self, in this regard, gains some schizophrenic aspect. Or does the artist meets himself with a masculine display pattern as young hooligans in bigger towns like to spit on the street? A starting point for Spit was a photographic series in which Kunkel collected photos of spittle in the city. Childhood games like spitting cherry stones as far as possible or who has more spittle in his mouth (Collecting as much saliva as possible in one s mouth to imagine lemons is helpful and then making a huge blob on the ground) lie in the ...

One of the questions addressed in the report was the use of Conservation Reserve Program land for bioenergy production.. If you are not familiar with the program: 32 million acres of cropland are enrolled in CRP, and farmers receive an average payment of $57 per acre per year in a program designed to reduce crop production, diminish soil erosion, and improve water quality on highly erodible agricultural lands.. The program was developed back in an era when there was more land available for production agriculture than markets could support in food, feed and bioenergy demand - keeping land out of production helped support crop prices while improving land quality and was also aimed to improve wildlife habitat..

KINGSVILLE, Texas -- From a laptop computer in a university classroom beams a long list of letters and numbers -- an equation, Les Nunn tells his colleagues in cowboy hats, for getting the most beef out of your pastures grass.
Pretty, isnt it?. But it was not enough.. For one thing, the art is very realistic. Its not picture perfect (blue lion mutants with glasses dont actually exist), but its styled to be real. The artist likes to include things like red lines in the eyes, to show the craziness of the villain or spittle flying to show that people are shouting.. Unfortunately, the craziness comes off more like caaaaaaaarrrraaaaaziness and the spittle just seems sort of gross. The story is just-irritating, and the art could be so awesome, and yet it doesnt all mesh the way a visually told story should.. Instead of making me look forward to more or compensating, the art just reinforced those parts of the story that pissed me off. The basic plot is that the X-Men have found the source of some fake mutants. Their ex-fellow, Forge, has gone bastshit (as one does) and started to make fake mutants to combat evil warriors from an alternate dimension. Theyve denned Forge in his lair in order to stop him.. And Forge ...

Beyond creating descriptive knowledge of organizational influences on campus sustainability, a major goal of the CESS and related research is to provide prescriptive advice for advocates. The following list of general recommendations summarizes this advice:. 1) Know Your Institution: While analysis of the CESS provides details on which organizational conditions are conducive to progress on sustainability and which are not, an important general finding for advocates is that knowledge about your institution translates directly into strategies that are more productive. Understanding institutional characteristics that affect perceptions and actions related to sustainability is a key precondition to developing an effective advocacy campaign.. 2) Diversify Your Allies: Campus sustainability efforts tend to arise from a small group of committed individuals with similar viewpoints and backgrounds. This study reveals that sustainability "allies" can and should come from many different disciplines and ...

Commonly, each somatic cell in an organism holds the same amount of DNA. However, researchers have, for the first time, shed light on a process, which leads to tissue-specific differing DNA content in plants. With an unusually high efficiency rate of 100%, this programmed chromosome elimination mechanism could become a valuable genetic tool for plant breeding or medical applications.

A series of investigations was undertaken to determine the acceptability of certain industrial wastes containing hexavalent chromium by a biodisc system providing both secondary treatment and biological nitrification. The initial objectives of the study were: to determine the extent to which a biodisc system can tolerate chromium (VI) without losing efficiency in either BOD removal or in nitrification; to establish mechanisms of chromium removal and the benefits of staging, and to understand differences in short and long-term effects and steady state or shock load conditions. These objectives were established to serve a number of purposes. The data gathered will assist municipalities in determining the quantity and characteristics of chromium containing waste that may be accepted without causing interference in operation. The data gathered will also assist design engineers in understanding and better defining the process reliability between an activated sludge and a biodisc system and finally the

I was planning try my hand at Magnolia ,breeding this spring. In the course of doing some research on the plants ,that I had intended to use as parents I found that one was a triploid. , I was under the impression that triploids are sterile but I recently ,read that triploids of some plants can be self fertile and can also ,produce fertile pollen. Like most things in biology, it depends. Triploids derived from true diploids are generally sterile because pairing problems in meiosis yield unbalanced gametes. If the plant species in question is a functional tetraploid, though, triploids derived from it will probably be somewhat fertile, since there are redundant copies of most or all genes. Of course, triploids can produce unreduced (3n) gametes, and these may be fertilized to yield tetraploids. The ratio of endosperm ploidy to embryo ploidy plays a ...
Repeated elements are remarkably important for male meiosis and spermiogenesis in Drosophila melanogaster. Pairing of the X and Y chromosomes is mediated by the ribosomal RNA genes of the Y chromosome and X chromosome heterochromatin, spermiogenesis depends on the fertility factors of the Y chromosome. Intriguingly, a peculiar genetic system of interaction between the Y-linked crystal locus and the X-linked Stellate elements seem to be also involved in male meiosis and spermiogenesis. Deletion of the crystal element of the Y, via an interaction with the Stellate elements of the X, causes meiotic abnormalities, gamete-genotype dependent failure of sperm development (meiotic drive), and deposition of protein crystals in spermatocytes. The current hypothesis is that the meiotic abnormalities observed in cry- males is due to an induced overexpression of the normally repressed Ste elements. An implication of this hypothesis is that the strength of the abnormalities would depend on the amount of the ...

Hi Heather: Been reading all the posts here and Im so sorry for your loss. We also live in Florida...Central and we dont have much pasture grass either. After much thought and discussion, we asked our boarding facility if we could put a large O&A Alfalfa block in the pasture for our two broodmares. We did and purchased our first one on Dec 15th. To give you an idea how long it lasts...I went out yesterday to check on them...it was gone...so it lasted about 10 days, but I expected the first one to go fast...it was their first time free feeding. The bale itself was a 554 pound bale. We are going to purchase our second one today and Ill keep you posted as to how long it lasts. They certainly enjoyed it and ate as they felt like it. Now my daughter has a 14.2 hh pony (little appy leopard) and he stays fat. She rides him 4-5 days per week and he barely gets 1 cup of feed twice a day and some coastal hay. He just stays fat and healthy. So I cant help you out there, cause any more feed for him and ...
New Opti-CleanseTM Psyllium-Based Supplement from Manna Pro Removes Sand from Horses GI Tract. Innovative product combines psyllium fiber with Diamond V XPCT yeast culture for added benefits.. Trusted livestock feed manufacturer Manna Pro has just introduced a new, psyllium-based horse supplement to aid in the removal of sand from the digestive tract. Opti-CleanseT helps support normal GI health and function in horses of all ages, and it is the only psyllium-based supplement enriched with Diamond V XPCT yeast culture for added palatability.. Dr. Rob McCoy, Manna Pros Vice President of Nutrition, says horses that are fed on the ground or consume pasture grasses and hays may ingest dirt and sand, which accumulate in the GI tract. "Over time, the dirt and sand will build up in the intestines and eventually cause discomfort," Dr. McCoy says, "and some adult horses may carry 30-60 pounds before showing signs of pain.". Although horses naturally rid their system of sand and dirt in their feces, the ...
Weve zeroed in on aluminum tolerance in maize and sorghum," Kochian says. "Aluminum is what limits root-system growth in acid soils. These crops are ideal for this project because in sorghum, aluminum tolerance is a simple trait, while in maize, the tolerance is complex." Kochians group and researchers at Brazils EMBRAPA Maize and Sorghum Research Center have cloned Alt SB, the major sorghum aluminum-tolerance gene. And recently, he and colleagues confi rmed the importance of a gene called AtALMT1 to aluminum tolerance in Arabidopsis. They also found that a second, still unidentifi ed, gene plays a major role in that plants aluminum tolerance in acidic soil.. Targeting Insect Vectors ...
