Germination ecology of neotropical pioneers: interacting effects of environmental conditions and seed size

TRH Pearson, DFRP Burslem, CE Mullins… - Ecology, 2002 - Wiley Online Library
Germination provides many potentially unrecognized sources of variation in the
regeneration niche. In this study we relate germination requirements and seed size for 16 …

Seed germination in a seasonal tropical forest in Panama: a community study

NC Garwood - Ecological monographs, 1983 - Wiley Online Library
Seed germination in the seasonal tropical forest on Barro Colorado Island, Panama, was
studied at the community level to (1) determine the seasonal timing of germination of the …

Functional significance of photoblastic germination in neotropical pioneer trees: a seed's eye view

TRH Pearson, DFRP Burslem, CE Mullins… - Functional …, 2003 - Wiley Online Library
Summary 1 We investigated the relationship between seed mass and the suitability of
microsites for germination for five small‐seeded (< 2· 4 mg fresh mass) photoblastic …

Germination responses to water potential in neotropical pioneers suggest large-seeded species take more risks

MI Daws, LM Crabtree, JW Dalling, CE Mullins… - Annals of …, 2008 - academic.oup.com
Abstract Background and Aims In neotropical forests, very small-seeded pioneer species (<
0· 1 mg seed mass) recruit preferentially in small tree fall gaps and at gap edges, but large …

Seed dispersal, seedling establishment and gap partitioning among tropical pioneer trees

JW Dalling, SP Hubbell, K Silvera - Journal of Ecology, 1998 - Wiley Online Library
1 We examined the abundance and distribution patterns of pioneer seeds in the soil seed
bank, and of pioneer seedlings in 53 recently formed gaps, in a 50‐ha forest dynamics plot …

Ecophysiology of seed germination in the tropical humid forests of the world: a review

C Vázquez-Yanes, A Orozco Segovia - … ecology of plants of the wet tropics …, 1984 - Springer
Most forest tree seeds from the humid tropics germinate soon after dispersal forming carpets
of semi-dormant seedlings. Delayed germination and enforced dormancy is frequent among …

The relationship between seed size and establishment conditions in tropical woody plants

S Foster, CH Janson - Ecology, 1985 - Wiley Online Library
Two approaches were used to examine the relationship between seed size and typical
establishment conditions in woody species of tropical rain forests. First we compared seed …

Seed size, growth rate and gap microsite conditions as determinants of recruitment success for pioneer species

JW Dalling, SP Hubbell - Journal of Ecology, 2002 - JSTOR
1 We examined how seed size and seedling growth rate influence recruitment success of
neotropical pioneer species. We investigated the soil seed bank, and followed seedlings …

The effect of leaf litter on early seedling establishment in a tropical forest

J Molofsky, CK Augspurger - Ecology, 1992 - Wiley Online Library
The presence of leaf litter of different depths within a tropical forest creates many different
microsites for plant establishment. The amount and distribution of leaf litter within a forest …

Short dry spells in the wet season increase mortality of tropical pioneer seedlings

BMJ Engelbrecht, JW Dalling, TRH Pearson, RL Wolf… - Oecologia, 2006 - Springer
Variation in plant species performance in response to water availability offers a potential
