Predicting the seasonal dynamics of bird communities along an urban-rural gradient using NDVI
(Elsevier Science, 2018-04-23)
The normalized difference vegetation index (NDVI) is a strong and widely used proxy for bird species richness in urban environments. However, its potential to predict composition and seasonal dynamics of bird communities ...
Seasonal variation in feeding habits and diet selection by wild boars in a semi-arid environment of Argentina
(Polish Academy of Sciences, 2013-01)
The wild boar, Sus scrofa, was first introduced for hunting purposes in Argentina in 1906 and presently occupies a wide range of habitats. Understanding the food habits of invasive species is important for predicting the ...
Seasonal variability of the oxygen minimum zone off Peru in a high-resolution regional coupled model
(European Geosciences Union (EGU), 2016-08-08)
In addition to being one of the most productive upwelling systems, the oceanic region off Peru is embedded in one of the most extensive oxygen minimum zones (OMZs) of the world ocean. The dynamics of the OMZ off Peru remain ...
Variation in the Thermal Parameters of Odontophrynus occidentalis in the Monte Desert, Argentina: Response to the Environmental Constraints
(Wiley-liss, div John Wiley & Sons Inc., 2012-03)
We studied the variation of thermal parameters of Odontophrynus occidentalis between season (wet and dry) in the Monte desert (Argentina). We measured body temperatures, microhabitat temperatures, and operative temperatures; ...
Diversity and seasonal fluctuation of predominant microbial communities in Bhitarkanika, a tropical mangrove ecosystem in India
(Universidad de Costa Rica, 2012)
Dependence of equatorial F region vertical drifts on season and solar cycle
(American Geophysical Union, 1979-10-01)
Vertical drift measurements have been made at Jicamarca for more than half a solar cycle. The data from periods of high and low activity are appreciably different. Daytime drift velocities during sunspot minimum are usually ...
Seasonal and pollution-induced variations in biomarkers of transplanted mussels within the beagle channel
(Pergamon-Elsevier Science Ltd, 2011-06)
The occurrence of biomarker variations linked to environmental factors makes it difficult to distinguish the effect of pollution. In an attempt to evaluate spatial and seasonal effects of environmental parameters on biomarker ...
Equatorial E region electric fields at the dip equator: 2. Seasonal variabilities and effects over Brazil due to the secular variation of the magnetic equator
(American Geophysical Union, 2016-09-23)
In this work, the seasonal dependency of the E region electric field (EEF) at the dip equator is examined. The eastward zonal (Ey) and the daytime vertical (Ez) electric fields are responsible for the overall phenomenology ...
Seasonal variation in the odour characteristics of whole milk powder
(2006-09-28)
Seasonal changes in whole milk powder odour characteristics were monitored using SPME-GC and E-nose methodologies. ANOVA
showed a significant effect of the season on dimethyl sulphide, n-pentanal, n-hexanal, and butyric ...
