The influence of niche and neutral processes on a neotropical anuran metacommunity
(Wiley-Blackwell, 2014-08-01)
One of the most important questions in ecology is the relative importance of local conditions (niche processes) and dispersal ability (neutral processes) in driving metacommunity structure. Although many studies have been ...
Spatial soil moisture mapping through multi-temporal analysis of ERS-SAR pri data
(1997-03-14)
The scattering of microwaves from soil depends on several surface characteristics, such as the roughness, vegetation and the moisture content of the top layer. Knowledge of the temporal and spatial distribution of this ...
General spatial spectral variation in rocky intertidal communities from three biogeographical regions
(2017)
Aim. Understanding general spatial patterns of multiple species is a central aim of biogeography. Spatial analyses of coastal marine assemblages have shown an emergent pattern in that the variability in population abundances ...
Spatial Variation of Dental Caries in Late Holocene Samples of Southern South America: a Geostatistical Study
(Wiley-liss, Div John Wiley & Sons Inc, 2016-05)
Objective: The spatial variation of dental caries in late Holocene Southern South American populationswill be analyzed using geostatistical methods. The existence of a continuous geographical pattern ofdental caries variation ...
Resonance scattering and spatial variation of the order parameter in superconducting alloys
(1971)
The problem of spatial variation of the order parameter in the neighborhood of a nonmagnetic impurity with broadened d levels is investigated near the superconducting critical temperature. It is shown that, due to resonance ...
Matching spatial scales of variation in mussel recruitment and adult densities across southwestern Atlantic rocky shores
(Elsevier Science, 2015-01)
The recruitment of aquatic invertebrate larvae often differs in space and time thus contributing to variation in the abundance of adults. In the present study, we examined spatial scales of variation in mussel (Brachidontes ...
Spatial Variation in Morphometry in Vanzosaura rubricauda (Squamata, Gymnophthalmidae) from Open Habitats of South America and its Environmental Correlates
(Soc Brasileira Herpetologia, 2013-12-01)
Patterns of geographical variation in morphology provide an empirical framework for testing the effects of ecological and historical factors on species differentiation. Environmental gradients play an important role in ...
Spatial variation in bird species abundances: Environmental constraints across southern Neotropical regions
(Elsevier Gmbh, Urban & Fischer Verlag, 2013-03-23)
Climate and habitat type are frequently related with the abundance of individual species and have been hypothesized to be primary drivers of the spatial variation in species abundances at the regional scale. Our aim is to ...
Spatial and seasonal variation of macroalgal biomass in Laguna Ojo de Liebre, Baja California Sur, México
(Hydrobiologia, 2003)
Laguna Ojo de Liebre is part of El Vizcaíno Biosphere's Reserve, one of the largest protected natural areas in the world. The contribution of seaweeds to the lagoons' total biomass had not been previously quantified. The ...
