Expanding our understanding of leaf functional syndromes in savanna systems: the role of plant growth form
The assessment of leaf strategies has been a common theme in ecology, especially where multiple sources of environmental constraints (fire, seasonal drought, nutrient-poor soils) impose a strong selection pressure towards ...
Divergent environmental preferences and areas of sympatry of tick species in the Amblyomma cajennense complex (Ixodidae)
Four species of Neotropical ticks, Amblyomma mixtum, Amblyomma cajennense, Amblyomma tonelliae and Amblyomma sculptum (formerly included in the catch-all name A. cajennense), have an allopatric distribution in much of their ...
Modelling the ecological niche of an endangered population of Puma concolor: First application of the GNESFA method to an elusive carnivore
Throughout central Argentina the distribution of puma (Puma concolor) has substantially contracted and appears to be restricted to relatively pristine areas. We identified factors affecting puma habitat use at a landscape ...
The long and the short of it: a global analysis of hawkmoth pollination niches and interaction networks
(Wiley Blackwell Publishing, Inc, 2017-01)
Proboscis length has been proposed as a key dimension of plant pollination niches, but this niche space has not previously been explored at regional and global scales for any pollination system. Hawkmoths are ideal organisms ...
Two bromeliad species with contrasting functional traits partition the understory space in a South American xerophytic forest: correlative evidence of environmental control and limited dispersal
We examined the spatial distribution of two bromeliad species with contrasting functional traits in the understory of a xerophytic South American Chaco forest. Aechmea distichantha is a facultative terrestrial species with ...
Evolução das tolerâncias climáticas em leguminosas arbóreas neotropicais
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM SISTEMÁTICA E EVOLUÇÃO, 2016-03-11)
The neotropical region has a high diversity of vascular plant that is correlated with many variables, such as with the climatic factors. Changes in the ecosystem can facilitate ecological opportunity and promote adaptive ...
Patterns of spatial distribution in macroalgal communities from tropical lotic ecosystems
(Sociedade Botânica de São Paulo, 2006-12-01)
Foram analisados três pontos em cada uma das três seguintes regiões tropicais: 1) região Noroeste do Estado de São Paulo, representando região degradada; 2) região de Bonito, Mato Grosso do Sul, representando ambiente de ...
Existence and decay of solutions to the dissipative quasi-geostrophic equation with delays
(Pergamon-elsevier Science LtdOxfordInglaterra, 2012)
Adult feeding moths (Sphingidae) differ from non-adult feeding ones (Saturniidae) in activity-timing overlap and temporal niche width.
(Oecologia, New York, v. 180, n. 2, p. 313-324, 2016., 2016)
Niche segregation facilitates coexistence between native and introduced fishes in a deep Patagonian lake
Species introductions force sympatry between species that did not coevolve. Introduced salmonids have coexisted with native fish since the early 20th century in Patagonian water bodies, thus generating questions about the ...
