The dimensionality of ecological networks
(2013-05-01)
How many dimensions (trait-axes) are required to predict whether two species interact? This unanswered question originated with the idea of ecological niches, and yet bears relevance today for understanding what determines ...
Trait-mediated effects on flowers: Artificial spiders deceive pollinators and decrease plant fitness
(Ecological Soc Amer, 2008-09-01)
Although predators can affect foraging behaviors of oral visitors, rarely is it known if these top-down effects of predators may cascade to plant fitness through trait-mediated interactions. In this study we manipulated ...
Leaf anatomical traits are correlated with tree dominance in a Neotropical deciduous forest
(2013-08-02)
Deciduous forests from the neotropics are one of the most endangered forest types in the world due to the exploitation of their natural resources by mankind. Many aspects of these ecosystems have been studied; however, ...
Seasonal variation in leaf traits between congeneric savanna and forest trees in Central Brazil: Implications for forest expansion into savanna
(2013-08-01)
The ecology of forest and savanna trees species will largely determine the structure and dynamics of the forest-savanna boundaries, but little is known about the constraints to leaf trait variation imposed by selective ...
The functional biogeography of species: Biogeographical species roles of birds in Wallacea and the West Indies
(2013-10-01)
Biogeographical systems can be analyzed as networks of species and geographical units. Within such a biogeographical network, individual species may differ fundamentally in their linkage pattern, and therefore hold different ...
Descrição cariotípica de possíveis novas espécies do complexo Hypostomus ancistroides e outros Hypostominae
(2012-04-04)
Cytogenetic analyses were performed in four species of the Hypostominae subfamily, three from Hypostomus (Hypostomini) genus and Rhinelepis aspera (Rhinelepini). Three populations of Hypostomus ancistroides were analyzed, ...
Modeling Habitat Split: Landscape and Life History Traits Determine Amphibian Extinction Thresholds
(2013-06-20)
Habitat split is a major force behind the worldwide decline of amphibian populations, causing community change in richness and species composition. In fragmented landscapes, natural remnants, the terrestrial habitat of the ...
Physiological traits and antioxidant metabolism of leaves of tropical woody species challenged with cement dust
(Ecotoxicology and Environmental Safety, 2018)
