Thermal requirements and germination niche breadth of Polygonum ferrugineum Wedd. from southeastern Brazil
(Cambridge University Press, 2021-05)
Temperature may regulate seed dormancy and germination and determine the geographical distribution of species. The present study investigated the thermal limits for seed germination of Polygonum ferrugineum (Polygonaceae), ...
The community-level effect of light on germination timing in relation to seed mass: a source of regeneration niche differentiation
(Wiley-Blackwell, 2014-11-01)
Within a community, species may germinate at different times so as to mitigate competition and to take advantage of different aspects of the seasonal environment (temporal niche differentiation). We illustrated a hypothesis ...
Many roads to success: different combinations of life-history traits provide accurate germination timing in seasonally dry environments
(2021-01-01)
Germination timing is determined by several plant life-history traits. Seed dormancy regulates the time and place of early plant development and spreads recruitment risks over time. Dispersal phenology and syndrome can ...
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
(Wiley Blackwell Publishing, Inc, 2015-08-26)
Seeds integrate environmental cues that modulate their dormancy and germination.Although many mechanisms have been identified in laboratory experiments, their contribu-tion to germination dynamics in existing communities ...
Thermal requirements of seed germination of ten tree species occurring in the western Brazilian Amazon
(2019-06-01)
Regeneration from seed affects species assembly in plant communities, and temperature is the most important environmental factor controlling the germination process. Thermal dependence of seed germination is thus associated ...
Germination characteristics of five coexisting neotropical species of Acacia in seasonally dry Chaco forests in Argentina
(Wiley Blackwell Publishing, Inc, 2017-04)
At a regional scale, habitat heterogeneity can play a very important role in allowing the coexistence of species through their specialization in the use of patches differing in environmental conditions. Here, we explore ...
