Summary • In Panama, abandoned agricultural lands that supported tropical rain forest are invaded by the exotic invasive grass Saccharum spontaneum, which precludes native forest regeneration. This study aimed to evaluate the importance of several barriers to forest regeneration and highlight mitigation opportunities. • We examined four barriers to...

We tested alternative hypotheses concerning factors affecting early forest succession and community composition in deforested and abandoned areas invaded by an exotic grass, Saccharum spontaneum , in Panama. We hypothesized three barriers to natural regeneration: (1) Saccharum competition, (2) seed dispersal limitations, and (3) fire. We measured n...

Deforestation in the tropics often leads to unproductive agriculture and results in abandoned, degraded grasslands that tree species recolonize poorly. To evaluate why forests do not regenerate naturally and to identify potential species for use in reforestation of degraded areas, we planted 15 000 seeds of 20 native tree species, varying in seed s...
Article
The Amazon harbors one of the most diverse tree floras on earth, and most species depend on mutualists for pollination and seed dispersal. This makes them susceptible to reproductive decline in fragmented forest because many of these mutualists suffer area‐related extinction in fragments. It remains unknown, however, whether this highly biodiverse...

We evaluated the composition, structure, and dieback of a montane forest in relation to soils and physiography of an important biogeographic region that has been sparsely studied. Our objectives were to (1) describe the forest composition and structure; (2) assess the current extent of dieback; and (3) relate tree composition, structure, and diebac...
Article
Little is known about how soil seed banks vary in germination, composition and density under different land uses after tropical forest conversion. Seed banks can potentially act as one source of regeneration for reforestation of old agricultural lands. Our study documents the composition and density of germinants in soil seed banks from four land u...

Few studies have been published that focus on monitoring and investigating the long-term patterns of recruitment and survival of seedlings in the understories of tropical forests. Studies for mixed dipterocarp forest, the dominant tropical forest type for South and Southeast Asia, demonstrate seedlings in the existing forest understory (advance reg...
Conference Paper
Background/Question/Methods Fragmentation of tropical forests is a major cause of global biodiversity loss, however the effects of forest fragmentation on the biodiversity and species composition of neotropical forest regeneration are poorly understood. We hypothesized that forest fragmentation negatively affects the diversity of regenerating neotr...

Bacterial communities mediate many of the processes in boreal forest floors that determine the functioning of these ecosystems, yet it remains uncertain whether the composition of these communities is distributed nonrandomly across the landscape. In a study performed in the southern boreal mixed wood forest of Québec, Canada, we tested the hypothes...
