Lauraceae have an ancient evolutionary history and wide distribution, providing a great model for studies of the biogeographical distribution patterns of plant species. The effects of elevational variation on plant diversity ...

Since many arid ecosystems are overstocked with domestic herbivores, biotic stress could have a stronger influence in modulating the balance of species interactions than expected from the stress gradient hypothesis (SGH). ...

Patterns of variation in plant-pollinator (p-p) systems in response to environmental variables have been the focus of much recent attention. We analyzed species diversity and generalization of interactions of flower visitors ...

The stress-gradient hypothesis (SGH) predicts that, although facilitation and competition occur together, facilitative interactions will be more prevalent with increasing abiotic stress. In water-limited ecosystems, support ...

The variation on the richness species in regional scales has been debated a lot. Three of the hypotheses mot frequently discussed as determinants of regional variability in richness species are energy, contemporary ...

This paper introduces a relative structural complexity measure for the characterization of disordered surfaces. Numerical solutions of 2d+1 KPZ equation and scanning force microscopy (SFM) patterns of porous silicon samples ...

Foram realizadas meta análises com o Gradiente Latitudinal de Riqueza de espécies, a Regra de Rapoport e sua interação para vertebrados ao longo de todo o Globo. Com os resultados é possível concluir que ambos os padrões ...
