Sources of variation in corn silage and total mixed rations of commercial dairy farms
(Elsevier Inc, 2018-04)
Information on sources of variation in feed and diet characteristics is needed to develop appropriate strategies to reduce uncertainty and to separate true variation from that associated with measurements. The objectives ...
Circadian and seasonal variation in the essential oil from Virola surinamensis leaves
(Elsevier B.V., 1997-10-01)
The essential oil from leaves of Virola surinamensis shows circadian variation in elemicin and in monoterpenes during the rainy season (February). The monoterpenes represents 50% of total volatile compounds during the dry ...

Characterization of GPS total electron content (GPS-TEC) in Antarctica from 2004 to 2011
(Istituto Nazionale di Geofisica e Vulcanologia, 2013-04)
The vertical total electron content (VTEC) obtained from 2004 to 2011 at Comandante Ferraz Brazilian Antarctic Station (62.1°S, 58.4°W) is analyzed to study the mean diurnal, seasonal and annual variations. The maximum ...
Sperm morphometric in males of the paper wasp Polistes simillimus
(Alma Mater Studiorum, Univ Bologna, 2018-06-01)
Intraspecific variation in sperm morphometric is widespread across animal taxa and it might be related to different aspects of sexual selection. Within social insects, it has only been documented for some bee and ant ...
Analysis of the morphological variation of Doryteuthis sanpaulensis (Cephalopoda: Loliginidae) in Argentinian and Brazilian coastal waters using geometric morphometrics techniques
(Springer Verlag, 2017-09)
Shape variation of individuals from three locations, two from Argentina and one from Brazil, was analysed by geometric morphometrics techniques. Individuals were weighed, measured, sexed, assigned to a maturity stage and ...
