Hantavirus cardiopulmonary syndrome is an emerging zoonosis in Brazil. Human infections occur via inhalation of aerosolized viral particles from excreta of infected wild rodents. Necromys lasiurus and Oligoryzomys nigripes appear to be the main reservoirs of hantavirus in the Atlantic Forest and Cerrado biomes. We estimated and compared ecological niches of the two rodent species, and analyzed ...
We investigated the richness, composition, and species relative abundance of a terrestrial small mammal community in a Deciduous Forest area in the austral boundary of the Atlantic Forest. The microhabitat use of the most common species was also investigated. Six rodents – Akodon montensis (Thomas, 1913), Oligoryzomys nigripes (Olfers, 1818), Sooretamys angouya (Thomas, 1913), Thaptomys nigrita...
Fifty-eight taxa of Odonata are herewith reported from Batanta Island (including Arefi and Birie Islands). One new species is described: Argiolestes varga sp. nov. The following ten to the Raja Ampat Islands: Papuagrion magnanimum (Selys, 1876), Gynacantha rosenbergi Kaup, 1867, Palaeosynthemis cf. cervula (Lieftinck, 1938), Diplacina smaragdina Selys, 1878, Nannophlebia amphicyllis Lieftinck, ...
تحقیق حاضر به منظور بررسی اثرات قارچ Lecanicillium muscarium روی میزان تخمریزی، طول عمر و رفتار جفتگیری زنبورهای نر و ماده Aphidius nigripes Ashmead انجام گرفت. سطوح مختلف آلودگی با محلول پاشی غلظتهای مختلف قارچ (شامل 105 و 107 اسپور در میلیلیتر به همراه شاهد، آب مقطر) و یا با نمونهبرداری در روزهای مختلف روی زنبورهای نر و یا ماده ایجاد شد. سپس امکان انتقال قارچ از فرد آلوده به فرد سالم در هن...
Although the Genus Oryzomys is widely distributed in the Americas, there are very few published data on the morphology of this rodent group. Notably, in relation to the digestive apparatus, the data are sparse and fragmented. In addition, because rodents are important animal models, this information may be useful in recent and promising areas for applied studies, such as clinical, therapeutic, ...
The first and only study on gastrointestinal parasites of wild rodents in the Island of Santa Catarina was done in 1987. The aim of this study was to identify intestinal parasites from wild rodents in Santo Amaro da Imperatriz and Santa Catariana Island, and to compare the richness and composition of the gastrointestinal parasite community of both areas. Rodents were captured with live traps, a...
Species with sexual dimorphism provide powerful study systems for understanding adaptation to different lifestyles as it removes the potentially confounding effects of phylogeny. Thynnine wasps have a stark sexual dimorphism where males fly patrols in search of the flightless, predominantly fossorial females with which to mate. Using flow-through respirometry, we tested the prediction that the ...
The present study aimed to investigate the antioxidant and antiradical activities of Wu Ling Shen, a popular medicinal fungus (Xylaria nigripes) used in traditional Chinese medicine preparations. Two different X. nigripes materials, the cultivated X. nigripes mycelia (XN) and a commercial X. nigripes product (XNP), were used to prepare the aqueous (XN-H vs. XNP-H) and ethanol (XN-E vs. XNP-E) e...
