Seed limitation in a Panamanian forest [PDF]
SummaryThe role of seed limitation in tropical forests remains uncertain owing to the scarcity of experimental evidence. We performed seed addition experiments to assess seed limitation for 32 shade‐tolerant tropical forest species and monitored the natural seed rain of 25 of these species for 17 years.One, two or five seeds were sown into 0.0079 ...

Natural experiment demonstrates that bird loss leads to cessation of dispersal of native seeds from intact to degraded forests. [PDF]
In healthy forests, vertebrate frugivores move seeds from intact to degraded forests, aiding in the passive regeneration of degraded forests. Yet vertebrate frugivores are declining around the world, and little is known about the impact of this loss on ...

The soil seed bank has a limited role in the seasonal dry tropical forest regeneration process, but seed removal and germination can also be limiting factors during the early forest recovery.

Planting the seeds for a forest of RNAi pathways
Cells from most eukaryotic species make several different types of small interfering RNAs. Pioneering work in plants, published in PLOS Biology almost 20 years ago, established a framework to understand how multiple RNA interference pathways can regulate the genome in parallel.

The Importance of Poneromorph Ants for Seed Dispersal in Altered Environments
Changes in species composition and an increase in the probability of local or regional extinctions alone are considered alarming consequences of human disturbances. However, these changes bring other damages that have passed unnoticed by scientists, such

Variability of pine cedar siberian seeds, which grow in different forest areas
The indicators for seeds of Pne cedar Siberian (Pinus sibirica Du Tour) growing in different forest areas of the Krasnoyarsk territory and Irkutsk region have been presented. The object of research was the seeds harvested in the 20 populations.

Long Distance Seed Dispersal by Forest Elephants [PDF]
By dispersing seeds long distances, large, fruit-eating animals influence plant population spread and community dynamics. After fruit consumption, animal gut passage time and movement determine seed dispersal patterns and distances. These, in turn, are influenced by extrinsic, environmental variables and intrinsic, individual-level variables.

Physiological and biochemical changes in Cedrela fissilis seeds during storage [PDF]
: The objective of this work was to evaluate the effect of storage on the physiological quality of cedar (Cedrela fissilis) seeds, as well as to correlate the germination and vigor of the seeds with their main biochemical changes.
