Blood-Feeding Ecology of Mosquitoes
To determine the unique host assemblages in zoos influence blood-feeding by mosquitoes a sampling programme was conducted in Greenville and Riverbanks Zoos. Mosquito-host associations generally conformed to previous accounts, indicating that mosquito behaviour inside zoos reflects that outside zoos
Effects of Nutrition in Culex Pipiens
Mosquito larvae face numerous biotic and abiotic challenges that affect their development and survivorship, as well as adult fitness. Nutrient-rich larval environments alleviated, in part, the effects of increasing density and extended the lifespan of mosquitoes fed on water and sucrose
Rollers Smell Nestlings Fear
Many animals react to danger by producing chemical cues that can be smelled by others which is called the smell of fear. Adult rollers are able to smell the fear of offspring and show for the first time in birds that a scent produced
Vocal Exploration is Regulated During Song Learning
Birds are trained to perform a one-syllable song and once they mastered it, a new syllable is added to the song model. When practicing the modified song, birds rapidly alternated between high and low acoustic variability to confine vocal exploration to the newly added syllable
Grey Treefrogs: Signal Recognition in Temporally Fluctuating Noise
In frogs, the benefits of dip listening are constrained by neural mechanisms underlying temporal pattern recognition. These constraints have important implications for the evolution of male signalling strategies in noisy social environments
Expression and Regulation of Macrophage Migration Inhibitory Factor (MIF)
Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine produced by many mammalian tissues. Quantitative reverse transcriptase PCR is used to study the gene expression in American dog tick during the first 96 h of feeding
Population Genetics of Asexually and Sexually Reproducing Psocids Species
Both L. bostrychophila and L. entomophila display high genetic diversity and widespread population genetic differentiation within and between populations due to genetic drift, inbreeding and less by geographic distance
Incidence of Hyperamylasemia after Endoscopic Ultrasound-Guided Fine Needle Aspiration
The incidence of hyperamylasemia after endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) gave few reports. Overall incidence of hyperamylasemia after EUS-FNA is low. The type of cystic lesion present and the gauge of the needle used for EUS-FNA represent risk factors for the incidence of hyperamylasemia
Focus on Malignant Transformation of Intraductal Papillary Mucinous Neoplasm
Malignant transformation(MT) of Intraductal Papillary Mucinous Neoplasm (D-IPMN) is not rare. The observation of morphological changes of main pancreatic duct and nodules mainly on contrast-enhanced endoscopic ultrasonography is practical and useful for predicting MT of BD-IPMN itself
Barrier in Severe Acute Pancreatitis
Glucagon-like peptide 2 administration improve the ileal mucosal injury. Immunohistochemical staining of proliferating cell nuclear antigen protein was increased in group 3 compared with that in group 2. GLP-2 has a protective effect on intestinal barrier dysfunction
Wolbachia and DNA Barcoding Insects
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation. Cytochrome Oxidase I gene is one of the five multi-locus sequence typing genes used for categorizing Wolbachia.
Integrated Pest Management & Organic Farming: Portuguese Strawberries
Pesticides are the most widely used chemicals in the world. Because of the widespread use of agricultural chemicals in food production, people are exposed to low levels of pesticide residues through their diets.
Changes in Offspring Sex Ratio in a Bat
Many organisms produce offspring with sex-ratios that deviate from equal numbers of males and females. In some species, offspring sex-ratio varies across the reproductive season again with several explanations.
Variation in Migratory Behavior in American Kestrel Populations
Birds employ numerous strategies to cope with seasonal fluctuations in high-quality habitat availability. Partial migration is especially common among broadly distributed species. Migratory behavior can evolve quickly in American Kestrel populations in North America.
Detection of Frog Calls in Wireless Sensor Networks
A method for detecting vocalization of giant barred frogs in noisy audio is proposed. Audio recordings from remote wireless sensor nodes were segmented into individual sounds and from each sound a small set of features was extracted.
