Pollination in the campo rupestre: A test of hypothesis for an ancient tropical mountain vegetation
(2021-06-01)
The campo rupestre is a Neotropical OCBIL (old, climatically buffered infertile landscape), a grassy-shrub vegetation with high species richness and endemism, characterized by rocky outcrops surrounded by grasslands ...
The asymptotic behavior of nonlinear eigenvalues
(Rocky Mt Math Consortium, 2007-12)
In this paper we study the asymptotic behavior of eigenvalues of the weighted one dimensional p Laplace operator, by using the Prufer transformation. We found the order of growth of the kth eigenvalue, improving the remainder ...

(BioMed Central, 2016)
Abstract
Background
Rickettsia rickettsii is vectored by ticks, and some vertebrate hosts can be sources of infection to ticks during bacteremic ...
The Late Cretaceous paleomagnetic field in North America: A South American perspective
(National Research Council Canada-NRC Research Press, 2011-11)
Determining the Late Cretaceous paleomagnetic pole for North America has been difficult because of the lack of suitable rocks of that age in cratonic areas to provide the necessary data. As an alternative, different studies ...
Exposure of dogs to spotted fever group rickettsiae in urban sites associated with human rickettsioses in Costa Rica
(2016-07)
The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae
in Latin America have usually been associated with rural or sylvatic environments, although domestic
dogs can be ...

Padrões filogenéticos de comunidades vegetais em um gradiente altitudinal na Serra do Cipó, Minas Gerais, Brasil
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciências Ambientais - PPGCAmCâmpus São Carlos, 2019-05-30)
Since the beginning of ecology studies, scientists have been worried in exploring natural communities and how the vary across time and space, looking for patterns to describe. Mountains are often great systems to study ...
Interações planta-polinizador em vegetação de altitude na mata atlântica
(2016-01-01)
Tropical high-altitude vegetation is unique due to susceptibility to severe weather conditions in relation to lower formations, and by the peculiarity of its flora with many relictual components. Studies on plant-pollinator ...
