Hematocrit and blood chemistry values in three genera of captive hornbills

This study reports hematocrit and blood chemistry values for captive adult individuals belonging to three genera of hornbills (Bucerotidae), Aceros, Anthracoceros, and Ceratogymna, and evaluates genera and gender specific differences in these values. Ceratogymna differs significantly from the other two genera in the concentration of total proteins, cholesterol, triglycerides, phosphorus, potassium, and sodium. Blood glucose concentrations in Aceros were lower than those in the other two genera. Plasma levels of enzymes differed between Aceros and Ceratogymna. With respect to gender differences, Aceros males had greater plasma levels of alanine aminotransferase (ALT), calcium and phosphorus than did the females, and the Ceratogymna males had higher concentrations of triglycerides. Body mass was correlated with hematocrit, cholesterol, total proteins, and urea in Aceros and with calcium concentration in Ceratogymna. These results are the first data available on reference ranges of blood values in individuals of this family of birds and may therefore be very useful as a complementary diagnostic tool in the veterinary care of individuals of these species in captivity.

斑蚜科属间胚胎及成蚜毛序的演变(同翅目,蚜总科)

基于世界斑蚜科13亚科90属200种的资料,描述了胚胎毛序的基本类型和多样性。斑蚜科毛序的基本类型可分为3类,即胚胎和一龄若蚜所具有的原毛序,第2龄若蚜和部分第3龄若蚜具有的中毛序,以及部分第3龄若蚜、第4龄若蚜和成蚜所具有的后毛序。结合成蚜及不同龄期若蚜的毛序,系统分析了斑蚜科各亚科毛序演变的规律,认为大部分亚科的成蚜毛序基本保留原毛序的状态,个别类群具有典型的中毛序或后毛序;而且部分类群成蚜的原毛序在胚胎毛序的基础上,腹部背片Ⅲ、Ⅴ、Ⅶ的中毛发生侧向位移。     

国产画眉草亚族叶表皮微形态特征及其在属间关系上的意义

通过国产画眉草亚族叶片表皮的解剖观察,结合外部形态,对该亚族内6个属的属间关系进行了分析。结果表明：羽穗草属应是国产画眉草亚族中最原始的类群,最高级的类群仍数细画眉草属,而其余4属即画眉草属、弯穗草属、尖稃草属和镰稃草属的演化水平居于两者之间;画眉草属和弯穗草属可能直接起源于原始的羽穗草属,而较高级的尖稃草属和镰稃草属又可能直接起源于较原始的画眉草属,并在镰稃草属的基础上进而派生了最进化的细画眉草属。整个研究结果既弥补了前人演化理论的不足,又为今后族进化的全面探讨提供了参考。     

A Chitinolytic Actinomycete Complex in Chernozem Soil

A chitinolytic actinomycete complex in chernozem soil has a specific taxonomic composition, which differs from that of the actinomycete complex typically isolated on standard nutrient media containing sugars and organic acids as carbon sources. The actinomycete complex that was isolated by using nutrient media with chitin as the source of carbon and nitrogen was dominated by representatives of the genus Streptosporangium, and the actinomycete complex that was isolated by using nutrient media with sugars and organic acids as the carbon sources was dominated by representatives of the genus Streptomyces. The confirmation of the ability of actinomycetes to utilize chitin as a sole source of carbon and nitrogen came from the augmented length and biomass of the mycelium, the increased number and biomass of the actinomycete spores, the production of carbon dioxide, and the accumulation of NH₄ ⁺ ions in the culture liquid of the actinomycetes grown in the nutrient media with chitin.

Bacterial genera isolated from field-collected (Diapausing) and laboratory-reared cotton boll weevils, Anthonomus grandis (Coleoptera: Curculionidae)

Little data exist on the bacterial flora of the cotton boll weevil, Anthonomus grandis, which is a common insect pest to cotton farmers in the United States. This investigation determined the total numbers of aerobic and anaerobic bacteria in diapausing field-collected boll weevils and active adult laboratory-reared boll weevils. Identifications were made of aerobic genera isolated from field-collected and laboratory-reared boll weevils that had previously been surface sterilized. The genera found, in order of decreasing frequency, in the field-collected boll weevils were Lactobacillus, Erwinia, Flavobacterium, Enterobacter, and Pseudomonas. The genera found, in order of decreasing frequency, in the laboratory-reared boll weevils were Lactobacillus, Pseudomonas, Streptococcus, Erwinia, Enterobacter, and Flavobacterium, Lactobacillus was the most frequently found genus in both groups.     

A NEW LACEWING FAMILY (NEUROPTERA)FROM THE MIDDLE JURASSIC OF INNER MONGOLIA, CHINA

Abstract  A new family, Grammolingiidae of fossil lacewings is erected, of which 3 new genera and 6 new species are described and illustrated: Grammolingia boi . gen. nov. et sp. nov., Lithlingia rhra gen. nov. et sp. nov., Litholingia eumopha gen. nov. et sp. nov. and Litholingiu polychotom gen. nov. et sp. nov., Leptolingia jurassica gen. nov. et sp. nov. and Leptolingia tianyiensis gen. noc. et sp. nov. A key to genera within this new family is provided. All specimens described were collected from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. The present discovery demonstrates that present knowledge of the Jurassic Neuropetra fauna remains very poor. The fossil specimens are deposited in Yizhou Fossil Museum and Department of Biology, Capital Normal University, respectively.     

Automated Modular High Throughput Exopolysaccharide Screening Platform Coupled with Highly Sensitive Carbohydrate Fingerprint Analysis

Many microorganisms are capable of producing and secreting exopolysaccharides (EPS), which have important implications in medical fields, food applications or in the replacement of petro-based chemicals. We describe an analytical platform to be automated on a liquid handling system that allows the fast and reliable analysis of the type and the amount of EPS produced by microorganisms. It enables the user to identify novel natural microbial exopolysaccharide producers and to analyze the carbohydrate fingerprint of the corresponding polymers within one day in high-throughput (HT). Using this platform, strain collections as well as libraries of strain variants that might be obtained in engineering approaches can be screened. The platform has a modular setup, which allows a separation of the protocol into two major parts. First, there is an automated screening system, which combines different polysaccharide detection modules: a semi-quantitative analysis of viscosity formation via a centrifugation step, an analysis of polymer formation via alcohol precipitation and the determination of the total carbohydrate content via a phenol-sulfuric-acid transformation. Here, it is possible to screen up to 384 strains per run. The second part provides a detailed monosaccharide analysis for all the selected EPS producers identified in the first part by combining two essential modules: the analysis of the complete monomer composition via ultra-high performance liquid chromatography coupled with ultra violet and electrospray ionization ion trap detection (UHPLC-UV-ESI-MS) and the determination of pyruvate as a polymer substituent (presence of pyruvate ketal) via enzymatic oxidation that is coupled to a color formation. All the analytical modules of this screening platform can be combined in different ways and adjusted to individual requirements. Additionally, they can all be handled manually or performed with a liquid handling system. Thereby, the screening platform enables a huge flexibility in order to identify various EPS.
