Energetics of wave propagation leading to cold event in tropical latitudes of South America
(Springer, 2015-07)
This paper presents a new vision on the cold and cool events that affect the tropical region of South America, considering the dynamics and the energetics of wave train propagation associated with these systems. Through a ...
Incursion of tropically-distributed plant taxa into high latitudes during the middle Eocene warming event: Evidence from the Río Turbio Fm, Santa Cruz, Argentina
(Elsevier Science, 2021-08)
Plant species with predominantly tropical and subtropical modern distributions (or meso-megathermal species) penetrated into the highest southern latitudes of the American continent during the global warmest periods of the ...
The potential for comparative research across New World bird migration systems
(Wiley Blackwell Publishing, Inc, 2012-08)
For a migratory bird, the costs and benefits of utilizing a given migratory strategy vary according to the biotic (e. g., physiology) and abiotic (e. g., weather) constraints it experiences throughout the year. In the New ...
Energetics of wave propagation leading to frost events in South America: extratropical latitudes
(Wiley VCH Verlag, 2017-08)
The dynamics of wave propagation and energy associated with frosts in extratropical versus tropical South American latitudes is studied. A double wave train propagates through the southern hemisphere following the polar ...
Interacción de la Zona de Convergencia Intertropical del Pacíico Este con Sistemas tropicales
(2016-12)
Las estimaciones satelitales de Tropical Rainfall Monitoring Mission (TRMM) fueron usadas para calcular cuatro índices que describen las características de la Zona de Convergencia Intertropical (ZCIT), estos son: el centro ...
Local and continental correlates of the abundance of a neotropical cat, the ocelot (Leopardus pardalis)
(Cambridge University Press, 2008-03)
As top predators, wild cats play a key ecological role in tropical forests, but little is known about the factors that regulate their abundance. This study looked for correlates of ocelot (Leopardus pardalis) abundance at ...
A comparison of temporal turnover of species from benthic cnidarian assemblages in tropical and subtropical harbours
(Oxford, 2015)
An important component of species diversity which has recently received significant attention is the change in species composition across space, or beta diversity. Temporal turnover of species is an equally important ...
Phytoplankton composition, dominance and abundance as indicators of environmental compartmentalization in Jurumirim Reservoir (Paranapanema River), São Paulo, Brazil
(Kluwer Academic Publ, 2000-07-01)
Patterns in the spatial and temporal composition, dominance and abundance of the phytoplankton community of the Jurumirim Reservoir (Brazil) were studied during one year at ten different sampling stations. The main ...
