Abstract:
Within ant communities, the biotic resistance of native species against invasive ones is expected to be rare, because invasive species are often highly dominant competitors. The invasive Argentine ant (Linepithema humile (Mayr)) often demonstrated numerical dominance against its opponents, increased aggressiveness, and ability to quickly recruit to food. The present study aimed to assess the behavioral mechanisms involved in the interspecific competition between L. humile, facing either an invasive species (Lasius neglectus Van Loon, Boomsma and Andrásfalvy) or a native dominant species (Lasius niger (Linnaeus)). The resource exploitation by the Argentine ant was investigated during one-hour competitive interactions using 10 dead Drosophila flies as prey. When facing La. niger, L. humile exploratory behavior was strongly inhibited, it brought very few prey resources, and killed few opponents. Conversely, La. neglectus had a low impact on L. humile. Contrarily to expectations, the invasive La. neglectus lacked the ability to hinder L. humile resource exploitation, whereas the native La. niger did. These results suggest that La. niger could impact invasive populations of L. humile by interference competition, perhaps better so than some invasive species. While L. humile has become invasive in Southern Europe, the invasion process could be slowed down in the northern latitudes by such native dominant species.

Abstract:
Although it is increasingly clear that exotic invasive species affect seed-dispersal mutualisms, a synthetic examination of the effect of exotic invasive species on seed-dispersal mutualisms is lacking. Here, we review the impacts of the invasive Argentine ant ( Linepithema humile ) on seed dispersal. We found that sites with L. humile had 92 per cent fewer native ant seed dispersers than did sites where L. humile was absent. In addition, L. humile did not replace native seed dispersers, as rates of seed removal and seedling establishment were all lower in the presence of L. humile than in its absence. We conclude that potential shifts in plant diversity and concomitant changes in ecosystem function may be a consequence of Argentine ant invasions, as well as invasions by other ant species. Because very few studies have examined the effects of non-ant invasive species on seed-dispersal mutualisms, the prevalence of disruption of seed-dispersal mutualisms by invasive species is unclear.

Abstract:
AbstractAsian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is an invasive citrus pest in southern California, which secretes honeydew and has the potential to spread a lethal bacterial disease, huanglongbing, of citrus. In urban citrus, Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae), also an invasive pest, tends honeydew-producing hemipterans. We used field data to determine whether the mutualistic relationship between L. humile and six established species of honeydew producers may hinder or favor the establishment of D. citri and its biological control with Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) in citrus via competition or mutualism for ants, respectively. In the field, L. humile and D. citri are engaged in a mutualistic relationship. Ants harvest solid honeydew secreted by psyllid nymphs and tended more than 55% of observed D. citri colonies. Linepithema humile displayed a preference hierarchy when tending honeydew producers infesting citrus. It responded equally or less intensively to D. citri than to other honeydew-producing species. Consequently, the mutualism between L. humile and D. citri was affected by the presence of other honeydew-producing species, and the percentage of D. citri colonies tended by L. humile. The number of ants per D. citri colony also decreased as the number of other honeydew producers increased. Diaphorina citri density was also affected by the presence of other honeydew producers. Both colony size and the number of D. citri nymphs counted per tree decreased as the number of other honeydew producers increased. Our results indicate that competition between honeydew producers for the mutualist ant L. humile may hinder the establishment of D. citri by possibly facilitating increased biological control.

Abstract:
Pesticides are frequently used to eradicate invasive ant species, but pose ecological harm. Previous studies assessed non-target effects only in terms of the increase or decrease of abundance or species richness after pesticide applications. Positive effects of the release from pressure caused by invasive ant species have not been considered so far. To more accurately assess pesticide effects in the field, the non-target effects of pesticides should be considered separately from the positive effects of such releases. Here, we used monitoring data of ants and other invertebrates collected in a program for the eradication of the Argentine ant, Linepithema humile (Mayr), using fipronil. First, we separately assessed the effects of L. humile abundance and fipronil exposure on non-target ants and other invertebrates using generalized linear models. The abundance of L. humile and the number of pesticide treatments were negatively associated with the total number of non-target individuals and taxonomic richness. We also noted negative relationships between the number of individuals of some ant species and other invertebrate taxonomic groups. The L. humile × pesticide interaction was significant, suggesting that the abundance of L. humile affected the level of impact of pesticide treatment on non-target fauna. Second, we evaluated the dynamics of non-target ant communities for 3 years using principal response curve analyses. Non-target ant communities treated with fipronil continuously for 3 years recovered little, whereas those treated for 1 year recovered to the level of the untreated and non-invaded environment.

Abstract:
Control of Argentine ants, Linepithema humile (Mayr), around structures in urban settings requires an extensive and thorough use of existing registered sprays and baits. Barrier sprays must be thoroughly applied at maximum label rates to prevent ants from accessing structures. Although insecticides with systemic activity such as imidacloprid and thiamethoxam may ultimately reduce homopteran food sources for L. humile, quantifying the impact of such reductions has been difficult. Applications of bifenthrin and deltamethrin granules provide short-term reductions. Most commercial baits available for L. humile are not readily consumed by foragers, or they provide too rapid kill of workers. Consequently, none of the baits are consistently effective. Potential new active ingredients for baits such as fipronil, imidacloprid, and thiamethoxam provide about 50% kill within 3 days and are readily accepted by foragers. These toxicants are extremely promising in liquid bait formulations. No single control strategy or treatment has been consistently effective.

Abstract:
AbstractInvasive alien species pose a serious threat to the integrity and function of natural ecosystems. Understanding how these invaders alter natural communities is therefore an important aspect in predicting the likely future outcomes of biological invasions. Many studies have documented the consequences of invasive alien species on native community structure, through the displacement and local extinction of native species. However, sampling methods and intensities are rarely standardised across such studies, meaning that it is not clear whether differences in response among native communities to the same invader species are due to biological differences between the invaded regions, or differences in the methodologies used. Here we use a matched sampling methodology to compare the effects of the Argentine ant (Linepithema humile Mayr) on native ant community assemblages in two distinct biogeographical regions that share similar ecologies: Girona (Spain) and Jonkershoek Nature Reserve (South Africa). We found a strong negative association between L. humile presence and native ant species richness within both geographic regions. However, the effects differed between the two study regions: in Girona, a single native ant species (Plagiolepis pygmaea) persisted in invaded sites; by contrast, substantially more native ant species persisted at invaded sites in Jonkershoek Nature Reserve. In addition, in Jonkershoek Nature Reserve, the abundance of certain native species appeared to increase in the presence of L. humile. This study therefore demonstrates the potential variable effects of an invasive species in contrasting locations within different biogeographical regions. Future work should explore the causes of this differential resistance among communities and expand standardised sampling approaches to more invaded zones to further explore how local biotic or abiotic conditions of a region determine the nature and extent of impact of L. humile invasion on native ant communities.

Abstract:
The genus Elatostema J. R. Forst. & G. Forst. belongs to the tribe Elatostemateae Gaudich. (1830: 493) of the family Urticaceae. It is one of the largest genera in the family with c. 626 accepted names and mostly distributed from tropical to subtropical regions of Africa, Asia and Oceania (Tseng & Hu, 2015; Lin et al. 2018; Fu et al. 2019). Recently, Tseng et al. (2019) provided a new circumscription for the Elatostema S.l. based on the molecular phylogenetic studies and morphological characters. Perry (1951), while studying the New Guinean flora, described Elatostema humile L. M. Perry (1951: 378) from the Idenburg river of New Guinea. This is a later homonym of the Fijian species Elatostema humile A.C. Sm. (1942: 22) and so illegitimate according to article 53.1 of ICN (Turland et al. 2018). Therefore, a replacement name, Elatostema perryi is proposed here.

Goal. The study of different genetic origin collection samples of flax (Linum usitatissimum L.) for the frequency and intensity of callusogenesis and organogenesis in vitro conditions, the establishment of differences in convar. elongatum, intermedia and humile was the goal of our research. Results and Discussion. The L. usitatissimum L. species is significantly capable of forming callus and shoot regeneration in vitro under cultivation conditions with a photoperiod of 16 hours, relative humidity of 60 – 80 %, air temperature of 22 – 24°С and agarized Murashige and Skoog medium, supplemented 0.05 mg/L of 1‑naphthylacetic acid, 1.0 mg/L of 6‑benzylaminopurine and 30 g/L of sucrose. The frequency and intensity of callusogenesis and organogenesis depends on the genotype. Minimum and maximum values of signs were set for Глінум (UF0401603), Кром (UF0401494), Орион (UF0401867), Есмань (UF0402071), Белита (UF0402134), Nor Man (UF0401792), Mapun M.A. (UF0401819), Lisa (UF0401830), Taragvi (UF0401864), Visamo (1–356)/L. monnseo (UF0402178), Ручеек (UF0401897), Lirina (UF0401900), Опус (UF0402142), СКі‑1 (UF0402143), Ruta (UF0402228) samples. The frequency of callusogenesis was 15.0 – 100 %, the calus mass from one explant was 0.56 – 1.51 g, the frequency of organogenesis was 10.0 – 93.8 %, the number of shoots was 1.4 – 4.0 pieces and the height of the shoots was 0.78 – 2.37 cm. Conclusions. Collection samples of Глінум (Ukraine), Кром (Russia), Visamo (1‑356)/L. monnseo (Czech Republic), Ручеек (Russia) and СКі‑1 (USA) were the best of complex signs (callusogenesis frequency, organogenesis frequency and number of shoots). Elongata flax and humile flax are characterized by the highest frequency of callusogenesis and organogenesis on hypocotyl and epicotyl explants, intermedia flax forms the largest mass of callus from the explant, the number of regenerated shoots and their height, intermedia flax has the greatest variation of the studied signs.

Nematodes and protists can be transmitted to humans in many ways and little concern has been given to the mechanical transmission by ants. This study aimed at analysing how the eggs of Ascaris lumbricoides and cysts of Entamoeba coli could be mechanically transmitted to the man by Formicidae. Through the experiments using nests of Tapinoma melanocephalum, Linepithema humile and Monomorium pharaonis reared in the laboratory allied to observations of some 17 ant species in an urban park area in Mogi das Cruzes (SP), it was found that L. humile was capable of carrying eggs of A. lumbricoides both in the field and laboratory conditions (1 worker), as well as was Camponotus rufipes (2), Solenopsis saevissima (1) and Acromyrmex niger (1). The cysts of Escherichia coli were found over three workers of C. rufipes. Although the frequency of the workers found transporting pathogens was low, the capacity of common household species in carrying pathogens like nematodes and protists was demonstrated.

Abstract:
In this study we test whether Argentine ants (Linepithema humile) progressively reduce their response to a salient stimulus (alarm pheromone) with increased exposure over time. First, we used a two-chamber olfactometer to demonstrate three focal behaviors of Argentine ants that indicate an alarmed state in response to conspecific alarm pheromone and pure synthetic iridomyrmecin (a dominant component of L. humile alarm pheromone). We then measured how these behaviors changed after repeated exposure to conspecific alarm pheromone from live ants. In addition, we investigate whether there is a difference in the ants’ behavioral response after “short” (3 min) versus “long” (6 min) intervals between treatments. Our results show that Argentine ants do exhibit reduced responses to their own alarm pheromone, temporarily ceasing their response to it after four or five exposures, and this pattern holds whether exposure is repeated after “short” or “long” intervals. We suggest alarm pheromones may be perceived as false alarms unless threatening stimuli warrant a continued state of alarm. These results should be kept in mind while developing pheromone-based integrated pest management strategies.

Full text
Abstract:
Ants (Hymenoptera: Formicidae), especially the Argentine ant, Linepithema humile (Mayr), can be significant nuisance pests in urban and suburban environments. Conventional interventions have primarily relied on the use of chemical insecticides, namely fipronil and bifenthrin, applied as residual, contact treatments around the outside perimeter of infested structures. Despite tightening regulation limiting the scope of insecticide applications in urban settings, dependence on these products to manage ants continues, resulting in significant water contamination. The U.S. EPA, in response, has further restricted the use patterns of many insecticides used for ant control in professional and over-the-counter markets. The purpose of this review is to summarize the relevant literature associated with controlling nuisance pest ants, with emphasis on L. humile, without the use of liquid broadcast applications of EPA-registered insecticides while focusing on low-impact, alternative (to broadcast applications) pest control methods. Specific subsections include Trail Pheromone; Use of Behavior-Modifying Chemicals; Mass Trapping; Hydrogels, “Virtual” Baiting, and Exceedingly-Low Bait Concentrations; Food Source Reduction; Deterrents; and RNA Interference (RNAi).

Abstract:
Abstract Thirty-five broadleaf evergreens which are evergreen in USDA cold hardiness Zone 7 were screened using leaf discs in the laboratory for Zone 6 (-20C) temperatures. Field data were collected from the plants in the field after two consecutive nights with lows of-20C. Correlations between lab and field scores were high, demonstrating the usefulness of leaf discs in initially screening broadleaf evergreens for evergreeness. The method allows for a more thorough sampling of a taxon and may therefore give better results than using a limited number of larger leaf samples, such as whole leaves.

Abstract:
Bushy cashew (Anacardium humile A. St. Hill) is an endemic plant species to the Brazilian Cerrado, a region characterized by scarce and poorly distributed rainfall. The use of hydrogel, a water-retaining polymer that features massive water storage and promotes its release into the environment throughout time may be an alternative to reduce the frequency irrigation in the production of bushy cashew seedlings. This study aimed to evaluate the quality and early growth of bushy cashew seedlings as a function of hydrogel doses. The experimental design adopted was in five randomized blocks, with five hydrogel doses (0; 1,0; 2,0; 3,0; and 4,0 g L-1 of soil), and each plot consisting of 10 seedlings, totaling 250 plants. A Yellow Latosol with sandy-loam texture was used for seedling production. The growth evaluation was performed through the variables of emergence speed index, germination percentage, height, diameter, root volume, number of leaves, shoot dry mass, root dry mass, and the Dickson quality index. The results revealed a positive influence of the hydrogel on the growth and quality of bushy cashew seedlings, notably at the dose of 4 g L-1 of soil.

Abstract:
AbstractAnts act simultaneously as predators and as hemipteran mutualists, and thereby may affect the composition and population dynamics of a wide arthropod community. We conducted ant-exclusion experiments in order to determine the impact of ants on the infestation levels and parasitism of three of the most important citrus pests of western Mediterranean citrus: the honeydew producer Aleurothrixus floccosus Maskell (woolly whitefly) and the non-honeydew producers Aonidiella aurantii Maskell (California red scale; CRS) and Phyllocnistis citrella (Staiton) (citrus leafminer). The study was conducted in three commercial citrus orchards, each one dominated by one ant species (Pheidole pallidula, Lasius grandis or Linepithema humile) during two consecutive growing seasons (2011 and 2012). We registered a significant reduction of the CRS densities on fruits in the ant-excluded treatment in the three orchards and in the two seasons, ranging from as high as 41% to as low as 21%. Similarly, the percentage of shoots occupied by A. floccosus was significantly lower in the ant-excluded plots in the orchards dominated by P. pallidula and L. humile. No significant differences were registered in the percentage of leaf surface loss caused by P. citrella between ant-allowed and ant-excluded treatments in any case. We found no significant differences in the percent parasitism between ant-allowed and ant-excluded treatments for honeydew and non-honeydew producing herbivores. These results suggest that: (i) ant management should be considered in order to reduce herbivore populations in citrus and (ii) mechanisms other than parasitism (e.g., predation) might explain the differences in herbivore infestation levels between treatments.

Abstract:
AbstractLiquid sugar baits are well accepted by the Argentine ant Linepithema humile and are suitable for the chemical control of this invasive species. We evaluated how sugar concentrations affect the foraging behavior of L. humile individuals. We quantified feeding variables for individual foragers (ingested load, feeding time and solution intake rate) when feeding on sucrose solutions of different concentrations, as well as post-feeding interactions with nestmates. Solutions of intermediate sucrose concentrations (10–30%) were the most consumed and had the highest intake rates, whereas solutions of high sucrose concentrations (60 and 70%) resulted in extended feeding times, low intake rates and ants having smaller crop loads. In terms of post-feeding interactions, individuals fed solutions of intermediate sucrose concentrations (20%) had the highest probability of conducting trophallaxis and the smallest latency to drop exposure (i.e. lowest time delay). Trophallaxis duration increased with increasing sucrose concentrations. Behavioral motor displays, including contacts with head jerking and walking with a gaster waggle, were lowest for individuals that ingested the more dilute sucrose solution (5%). These behaviors have been previously suggested to act as a communication channel for the activation and/or recruitment of nestmates. We show here that sucrose concentration affects feeding dynamics and modulates decision making related to individual behavior and social interactions of foragers. Our results indicate that intermediate sucrose concentrations (ca. 20%), appear to be most appropriate for toxic baits because they promote rapid foraging cycles, a high crop load per individual, and a high degree of stimulation for recruitment.

Abstract:
The paper analyses the results of the ecological stability research of beech (Fagus sylvatica L.) stands at the alpine tree-line ecotone in the Ďumbier part of Law Tatras. The applied methodology by Vološčuk (2000) is based on the approximation of the current tree species composition with respect to the original ones, crown ratio, slenderness quotient, sanitary coefficient and vertical species profile of the stands. The resulting value of ecological stability of the stands, typologically classified into a group of forest types Fageto-Aceretum humile, was increased by approximation of 80.0–82.5%, slenderness quotient 0.55–0.60 m.cm−1 and sanitary coefficient. Vitality was assessed with regard to the most common damage to individual, more than 160-year-old beech trees at the alpine treeline ecotone in the form of necrosis. Vertical and horizontal structure of the stands was influenced mainly by dense tree clusters. The value of ecological stability was decreased by average crown ratio of individual trees ranging from 0.47–0.57. Based on the final index of ecological stability ES 16–24, beech forests in the alpine treeline ecotone may be considered as very stable.

Abstract:
The invasion of the Argentine ant, Linepithema humile (Mayr) (Hymenoptera, Formicidae) can alter the entire ecosystem with serious impacts on the native community structure (e.g., ant diversity) and processes (e.g., trophic interactions) leading to biodiversity loss and pest outbreaks. Most studies addressing these impacts have been conducted in natural or semi-natural areas, few are those conducted in agricultural ecosystems, such as citrus orchards. These are dominant agricultural ecosystems in Mediterranean landscapes. Furthermore, most studies have been conducted in a short span, not evidencing seasonal fluctuations. In this work, we assessed the ecological impact of the Argentine ant on the native ant communities in citrus orchards, in the region of Algarve, southern Portugal. By using principal response curve, we compared seasonal variation on ant assemblages in invaded and uninvaded citrus orchards foraging on tree canopy from a two-year sampling. The Argentine ant had a marked negative impact on the native ant community foraging on citrus canopy. In the uninvaded orchards, the native ant community had a rich assemblage composed of 16 ant species, in its majority (72%) controlled by the dominant species Lasius grandis Forel, Tapinoma nigerrimum (Nylander) and/or Pheidole pallidula (Nylander). In the invaded orchards, the native ant community was poorer and highly modified, mostly dominated by the Argentine ant (80%). Apparently, the only native ant species not affected by the presence of the Argentine ant was Plagiolepis pygmaea (Latreille). A significant negative effect was found between the proportion of infested trees by L. humile and the number of native ant species per orchard. Differences in the native ant community in the invaded and uninvaded orchards persisted over seasons and years. However, negative impacts were higher in the spring and summer, and less pronounced in the autumn. We discuss implications for citrus pest management.

Abstract:
Pepino mosaic virus (PepMV) was first detected in Spain in 2000 (1). The virus infects tomato (Lycopersicon esculentum Mill.) crops and causes a variety of symptoms including leaf distortion, chlorosis, mosaic, blistering of the leaf surface, green striations on the stem and sepals, and fruit discoloration. PepMV is present along the southern and eastern regions of Spain (provinces of Granada, Almeria, Murcia, Alicante, Valencia, and Barcelona), Balearic, and the Canary Islands. In the summer and autumn of 2001 and 2002, virus-like symptoms were observed in native plants growing in or around tomato fields in Murcia and Almeria provinces. To study the alternate hosts that may serve as virus reservoirs, 62 samples of 42 common weed species, including asymptomatic plants, were collected and analyzed for PepMV using double-antibody sandwich enzyme-linked immunosorbent assay with a commercial antiserum (DSMZ As-0554; Biologische Bundesantstal, Braunschweig, Germany). The following weed hosts tested positive for PepMV: Bassia scoparia (L.) Voss., Calystegia sepium (L.) R.Br., Chenopodium murale L., Convolvulus althaeoides L., Convolvulus arvensis L., Conyza albida Willd. ex Spreng., Coronopus sp., Diplotaxis erucoides (L.) DC, Echium creticum L., E. humile Desf., Heliotropium europaeum L., Moricandia arvensis (L.) DC., Onopordum sp., Piptatherum multiflorum (Cav.) Beauv., Plantago afra L., Rumex sp., Sisymbrium irio L., Sonchus tenerrimus L., and Taraxacum vulgare (Lam.) Schrank. The presence of PepMV in these weed species was confirmed using reverse transcription-polymerase chain reaction with primers specific for PepMV (2). Although the number of samples examined may be insufficient to assess precisely the role of weed reservoirs in outbreaks of PepMV, these findings reveal potential virus sources and contribute to further understanding of PepMV epidemiology in Spain.

Abstract:
The genus Jasminum L., of the family Oleaceae, includes many species occurring in the wild, or cultivated worldwide. A preliminary investigation based on inter-simple sequence repeats (ISSR) was performed to assess the genetic diversity among 28 accessions, representing nine species of Jasminum from various regions, representing a range of altitudes in Pakistan. A total of 21 ISSR primers were used, which produced 570 amplified bands of different sizes, with a mean polymorphic band percentage of 98.26%. The maximum resolving power, polymorphism information content, and index values of the ISSR markers recorded for primers 6, 16, and 19 were 0.40, 12.32, and 24.21, respectively. Based on the data of the ISSR markers, the resulting UPGMA dendrogram with the Jaccard coefficient divided the 28 accessions into two main clades. At the species level, the highest values for Shannon’s information index, polymorphism percentage, effective allele number, Nei’s genetic variations, and genetic unbiased diversity were found in Jasminum sambac L. and J. humile L., while the lowest were observed in J. mesnyi Hance and J. nitidum Skan. Based on Nei’s unbiased genetic identity pairwise population matrix, the maximum identity (0.804) was observed between J. elongatum Willd and J. multiflorum (Burm. f.) Andrews, and the lowest (0.566) between J. nitidum Skan. and J. azoricum L. Molecular variance analysis displayed a genetic variation of 79% among the nine populations. The study was aimed to established genetic diversity in Jasminum species using ISSR markers. With the help of this technique, we were able to establish immense intra- and interspecific diversity across the Jasminum species.

Abstract:
Background: Medicinal plants and their products are gaining global popularity due to their several health benefits. However, the biological activities of the vast majority of medicinal plant species have not been explored yet. In this study, we evaluated the enzyme inhibitory potential of six medicinal plant species involved in digestion, skin-related problems, and neurological problems. Methods: The 80% methanol extracts of leaves of six locally available plants from the Bagmati province of Nepal were analyzed for their flavonoids content, phenolics content, antioxidant activity, and enzymes inhibitory potential. Antioxidant activity was analyzed by the DPPH assay. Alpha-amylase inhibition was carried out by the DNSA method. Lipase, tyrosinase, elastase, acetylcholinesterase, and butyrylcholinesterase inhibitions were analyzed by using p-NPB, L-DOPA, AAAPVN, acetylthiocholine, and butyrylthiocholine as a respective substrate. Results: Among the analyzed plants species, Artocarpus heterophyllus displayed highest α-amylase (IC50=6.28 ± 0.01 μg/mL), lipase (IC50= 475.14 ± 3.17 μg/mL), elastase (IC50= 72.75 ± 3.41 μg/mL) and acetylcholinesterase (IC50= 68.66 ± 1.71 μg/mL) inhibition, whereas, Actinidia deliciosa displayed highest tyrosinase inhibition (IC50=139.87 ± 0.72 μg/mL) and butyrylcholinesterase inhibition (IC50= 18.32 ± 0.44 μg/mL). Furthermore, Jasminum humile showed no inhibitory tendencies against elastase and Lygodium japonicum showed no inhibition towards lipase and elastase at the given concentration range. Conclusions: Our study revealed that A. deliciosa and A. heterophyllus are the potential source of α- amylase, lipase, elastase, acetylcholinesterase, and butyrylcholinesterase inhibitors. Based on our findings, we concluded that the analyzed plant species are of great scientific interest to the pharmaceutical, cosmetics, and food industries.

Abstract:
In the conditions of the right bank of the Saratov region, the responsiveness of sugar sorghum varieties (Kapital, Sahara, Seviliya, Volonter, Chaika) to the application of humic preparations (K-Humate-Na with trace elements, Reasil Forte Carb-N-Humic and Reasil Forte Seed Start) was studied at the experimental field of “Rosorgo”. The aim of the research was to determine the greatest stimulating effect of humic preparations on selection-valuable traits, including seed yield. Pre-sowing treatment of seeds and vegetative plants with K-Humate-N with trace elements (a dose of 1.0 l/t+1.0 l/ha) proved to be the most effective in cultivating Chaika, Kapital and Sahara varieties. Depending on the variety, this allowed an additional 0.94-1.22 t/ha of seeds to be collected. The influence of Reasil Forte Carb-N- Humics (dose 1.0 l/t+2.0 l/ha) on the yield of Seviliya and Volonter varieties was quite high. The use of the drug increased seed productivity by an average of 0.85-0.94 t/ha over two years of testing. Humic preparations had a stimulating effect on the sowing quality of seeds, the length of the panicle and the weight of seeds from a single panicle.

This experiment was carried out to determine the effects of using L-carnitine and humate alone or in combination in quail diets on laying performance, egg traits and blood parameters. A total of 280 Japanese quails aged 10 weeks, divided into one control group and three treatment groups, were used. The diets of the first, second and third treatment groups were supplemented with 100 mg L-carnitine/kg, 1.5 g humate (Farmagülatör® Dry Plus)/kg and 100 mg L-carnitine + 1.5 g humate/kg, respectively. The experimental period lasted 16 weeks. The addition of L-carnitine and sodium humate alone or in combination did not significantly affect body weight, feed consumption, egg production, feed conversion ratio, mortality, egg-shell thickness, egg yolk index and the percentages of egg-shell, albumen and yolk. Egg weight increased (P < 0.001) with L-carnitine supplementation. The values of egg albumen height (P < 0.05), egg albumen index (P < 0.01) and egg Haugh unit (P < 0.05) were increased with humate supplementation. Egg cholesterol content and blood serum parameters were not affected by the supplementation of L-carnitine with or without humate. The results in this study demonstrated that L-carnitine supplementation increased egg weight while humate addition increased egg albumen index and egg Haugh unit of laying quails. However, the combined administration of L-carnitine and humate did not have any significant effects on the parameters measured.

During the 2010-2012 period the influence of some bioproducts being mainly a combination of macro and micronutrients at different concentrations on the productivity, botanical and morphological composition of bird?s foot trefoil swards was studied. The experiment was carried out on the experimental field of the IMSA - Troyan by the completely randomized method with 4 replications and harvest plot size of 5 m2. Four bio-products phosphorus humate in dose of 3000 l/ha, boron humate (1600 l/ha) and molybdenum humate (1600 l/ha) and their combination phosphorus humate (2500 l/ha) + boron humate (1000 l/ha) + molybdenum humate (1000 l/ha) were studied. They were applied at the 2-4 leaf. The results showed that solely phosphorus humate had a positive influence, which increased the dry matter yield only by 8.7% and the results were not statistically significant.. It was found that the data had a unidirectional character with regard to the leafiness degree during the years as a result of the applied bio-fertilizers. Their application had a positive effect on the leafiness. The phosphorus humate showed a tendency to increase the relative portion of stems in the sward from the first to the third year. The kind of the applied bio-fertilizers was not of substantial importance to the degree of stem growth and botanical composition of the sward.

Humus is the stable form of added crop and animal residues. The organic matter after a long-term decomposition process converts into humic substances. The naturally occurring humus is present in less amount in soils of the arid and semi-arid regions.

The present study was conducted to evaluate the effect of potassium humate, applied through soil seed dressing, on cotton productivity and fiber quality attributes. Seed dressing with potassium humate was done at the rate of 0, 100, 150 and 200 mL kg−1 seed while in soil potassium humate was applied at the rate of 0, 10, 20 and 30 L ha−1. Results showed that the combined application of potassium humate by seed dressing and through soil application improved the soil properties, productivity and fiber quality traits of cotton. All levels of soil applied potassium humate (10, 20 and 30 L ha−1) performed better over seed dressing in terms of cotton productivity and fiber quality attributes. Among the soil application rates, 20 L ha−1 potassium humate proved better as compared to other rates (0, 10 and 30 L ha−1). Higher soil application of potassium humate (30 L ha−1) showed depressing effects on all the traits studied like the reduction of 12.4% and 6.6% in Ginning out turn and fiber length, respectively, at a seeding dressing of 200 mL kg−1. In conclusion, potassium humate seed dressing and soil application at the rate of 200 mL kg−1 and 20 L ha−1, respectively, is a better approach to improve cotton productivity. Soil potassium humate should not exceed a rate of 20 L ha−1 when the seed dressing of potassium is also practiced.

Abstract:
Compte tenu de l'importance que revêtent les salmonelles comme agent de mortalité et de morbidité, notamment chez l'enfant, il a été décidé d'étudier la prévalence de ces bactéries avec la collaboration des autorités de Guinée-Bissau, par une enquête épidémiologique à l'abattoir de Bissau. Le taux de prévalence sur 117 bovins abattus et reconnus aptes à la consommation humaine a été de 13,7 %, dont 8,5 % dans les prélèvements intestinaux et 5,1 % dans les vésicules biliaires. Les écouvillonnages rectaux, sur 74 autres animaux vivants, n'ont permis qu'un seul isolement : S. stanleyville. En revanche, aucune souche n'a été isolée dans les ganglions lymphatiques hépatiques. Ces souches, dont certains sérotypes sont pathogènes pour l'homme, sont en majorité dites "exotiques" : S. bargny, S. brazzaville, S. virchow, S. rubislaw, S. brazil, S. calabar, S. havana, S. hull, S. marseille, S. shipely, S. uppsala, S. ll4, 12; l,w; e,n,x. Un nouveau sérotype est décrit : S. 28; f,m,t : -. Isolé du contenu intestinal, ce sérotype présentait des fimbres MSHA (++++) et une DL 50 de 7,0 Log 10. La majorité des souches présentaient une antibiorésistance, soit simple, soit multiple. Les isolements ont été plus fréquents en saison humide qu'en saison sèche.

Abstract:
Three new species of Lepraria, L. celata, L. humida, and L. sylvicola, are described from Europe. They each possess a finely granular unstratified thallus containing fatty acids and atranorin, but can be distinguished from each other by the type of fatty acids present and by their ecology. Anthraquinones are present in subthalline hyphae of L. humida and L. sylvicola, and are also reported for L. atlantica. Toensbergianic acid can be produced by L. jackii as a minor compound. A key is presented to species of Lepraria containing fatty acids and atranorin as major substances.

Abstract:
To address taxonomic problems stemming from treatments in the Flora of Turkey and other publications, Tulipa is revised for Turkey. Following detailed morphological and cytotaxonomic studies of the taxa, Tulipa in Turkey has been found to be represented by 17 species, two subspecies and two varieties (in total 19 taxa). A new key for the species and detailed descriptions of taxa are provided, as are synonyms and typification as far as possible, distribution, habitat types, localities and conservation status of all taxa. These studies are based on approximately 1000 fresh and 2000 herbarium specimens. Adopting the classification of Van Raamsdonk & De Vries, Tulipa is divided into two subgenera, Eriostemones and Tulipa, which were previously treated as sections by Marais in Flora of Turkey following Boissier’s classification. Tulipa subgenus Eriostemones is divided into two sections following Baker's treatment: Sylvestres and Saxatiles. However, section Sylvestres is again divided into two subsections following Baker and Hall's treatments: Sylvestres and Biflores (here described). Section Saxatiles is further divided into three subsections, with the addition of two new subsections: Saxatiles, Orphanidetes and Humiles. The type subgenus Tulipa is divided into two sections: Tulipa and Clusianae. In subsection Humiles, T. pulchella is accepted at species rank, having usually been placed as a synonym of T. humilis. Some previously uncollected species (T. raddii and T. saxatilis) and a doubtful record (T. clusiana), after the first collection of material in Turkey, have been recollected and verified.

Abstract:
The calculation experiments of adsorption capacities of Th-232 and U-238 in γ- Al2O3-humate at single system and competitive with Freundlich method has been done. The purpose of the research is (1) to characterize γ- Al2O3-humat functional groups, (2) to know γ- Al2O3-humat solubility and (3) to predict adsorption capacities of U-238 and of Th-232 at adsorbent γ-Al2O3-humate. The characterization of functional groups γ- Al2O3-humate is done by Fourier Transform Infra red (FTIR) Spectrometry. Based on perception results of functional spectra characteristic of γ-Al2O3-humate is similar with humic substance with decrease at stretching -OH at 3400 - 3300 cm-1, and C=O stretching of COOH spectra, C=C aromatic or hydrogen bond of C=O at 1725-1720 cm-1spectra. The solubility testing of γ-Al2O3-humate indicated that the compound it's effective used as adsorption U-238 and of Th-232 at pH 1 to 4 conditions. At single adsorption system with 1000 mg/L of U-238 or Th-232 feed, 0.001 g up to 0.1 g weight of γ-Al2O3-humate were got for U-238 balanced to 992.15 mg/L and 980.66 mg/L for Th-232. By using regression line curve between ln C and ln x/m, adsorption capacities of U-238 and Th-232 at single system can be calculated as 3.63 mg/g and 2.93 mg/g, respectively, while adsorption capacity of Th-232 was increases to 8.08 mg/g and U-238 decreases to 0.91 mg/g at competitive system.

Abstract:
Sodium humate increased the acid phosphatase activity of fraction II of imbibing maize caryopses and suppressed the enzyme activity in fraction I. Removal of the testa changed the stimulating action of humate on the acid phosphatase activity of fraction II into an inhibiting one and intensified its unfavourable effect on this enzyme's activity in fraction l. Sodium humate inhibited the acid phosphatase activity of this fraction from both leaves and roots. The results obtained are in agreement with the theory of free radicals of humus substances being involved in action on biuecmbranes.

Ce texte aborde de façon métaphorique la notion de préconscient en tant que « zone intermédiaire », et le rôle de cette instance dans le fonctionnement de l’appareil psychique. Un cas de figure tiré de l’histoire contemporaine et la référence à une facette de la société technologique actuelle, permettent d’illustrer la résistance de plusieurs à l’égard de cette zone claire-obscure de la psyché. La psychothérapie psychanalytique de groupe est évoquée comme moyen privilégié d’approcher l’« humide ».
