This paper describes the variation of the above-ground biomass, necromass, and net above-ground primary production (NAGPP) of two weed species, Panicum maximum Jacquin (Poaceae) and Pteridium arachnoideum (Kaulf.) Maxon. (Dennstaedtiaceae), at two si

Temporal variation in rainfall and temperature, which is likely to increase in frequency due to climate change, may cause changes not only in the endogenous rhythms of organisms, but also in their phenology. This is of great concern, because ecologic

Germination rate and seed mass are important factors determining the proportion of seedlings that become established in a habitat, especially where resources are limited and under adverse environmental conditions. Variation in seed attributes can det

Although palms play an important ecological role in tropical forests, characteristics related to their germinative niche remain largely unknown. We evaluated the seed germination characteristics of Geonoma schottiana, an abundant palm in the understo

Niche germination breadth may determine species occurrence under distinct environmental conditions. We choose Euterpe edulis and Lytocaryum weddellianum to evaluate germination niche breadth under light or dark at water potential of 0 MPa, and in eit

Large seed banks have been found in tropical dry forests and also in habitats with high seasonality in rainfall. However, patchily structured vegetation could induce great spatial variation in the seed bank. We characterized the seed bank in a patchy

The spatial and temporal fluctuations of water availability can be an obstacle for recruitment of many species in the restinga and might restrict seed germination and seedling growth in specific regeneration safe-sites. Clusiahilariana is one of the

Seed germination is determined by the environmental conditions typical of a habitat and also by the geographical origin of the source species pool. During the Quaternary, Brazilian Atlantic Rain Forest species expanded their distribution into the san
