A high number of tree species, low density of adults of each species, and long distances between conspecific adults are characteristic of many low-land tropical forest habitats. I propose that these three traits, in large part, are the result of the action of predators on seeds and seedlings. A model is presented that allows detailed examination of the effect of different predators, dispersal agents, seed-crop sizes, etc. on these three traits. In short, any event that increases the efficiency… Expand
Seed predation and the coexistence of tree species in tropical forests
TLDR
It is concluded that other factors than seed predation limit the abundance of tropical tree species and prevent single-species dominance. Expand
Comparison of Herbivores and Herbivory in the Canopy and Understory for Two Tropical Tree Species1
TLDR
The results suggest that the potential of adult trees as a source of herbivore on saplings depends on the value of new leaves to a tree species' herbivores, which may differ across tree species. Expand
Insect herbivory on seedlings of rainforest trees: Effects of density and distance of conspecific and heterospecific neighbors
TLDR
The elevated rates of seedling herbivory at high densities of conspecifics documented in this study are consistent with the predictions of the Janzen–Connell hypothesis, and highlight the possibility that herbivore‐mediated density‐dependence, facilitated by herbivores that feed on multiple plant species, can also occur across plant species.

A test of the escape and colonization hypotheses for zoochorous tree species in a Western Amazonian forest
TLDR
The ratio between saplings and seedlings was higher away from parent trees for the species with enough recruitment to be analyzed and this suggests that a negative distance-dependent effect may also occur after seedling establishment, as predicted by the colonization hypothesis. Expand
Plant-animal interactions and the structure and function of mangrove forest ecosystems*
TLDR
Because of the relatively low species richness of trees and consumers in tropical mangrove forests, they are likely to serve as productive sites for further investigations of the influence of plant-animal interactions on the dynamics of tropical forests. Expand
On the causes of gradients in tropical tree diversity
1 The number of woody species in tropical forests tends to increase with precipitation, forest stature, soil fertility, rate of canopy turnover and time since catastrophic disturbance, and decreaseExpand
An assessment of post-dispersal seed predation in temperate rain forest fragments in Chiloé Island, Chile
TLDR
It is concluded that season and habitat are the most important variables determining the intensity of seed predation in forest fragments and the regeneration of woody species, particularly in forest interior, may be affected by post-dispersal seed consumption by vertebrates. Expand
Influence of frugivore activity on the species abundance of seedlings and saplings in a lowland tropical forest in Colombia
TLDR
The findings suggest that recruitment success is context-dependent as the relative importance of the different variables addressed may shift along spatial and temporal scales. Expand
Maintenance of forest species diversity and latitudinal gradient
The species diversity of trees maintained in tropical rain forests is much higher than in temperate, boreal, or seasonally dry tropical forests. Many hypotheses have been proposed for higherExpand
MAINTENANCE OF FOREST SPECIES DIVERSITY AND LATITUDINAL GRADIENT
TLDR
Analysis of a mathematical model shows that the existence of unfavorable season can greatly reduce the diversity of coexisting species and diversity in the equilibrium community can be high when niche width of each species is broad and resource use is strongly overlapped. Expand

Relationships between Fruiting Seasons and Seed Dispersal Methods in a Neotropical Forest
TLDR
The weight of fruits and seeds that fell into 75 polyethylene sheets, each 152 x 152 cm, totalling 175 m2 in area, was measured over a period of 17 months in the humid forest of Barro Colorado Island, in the Panama Canal Zone, to study the determinants of fruiting times. Expand
Some Attempts to Estimate Species Diversity and Population Density of Trees in Amazonian Forests
TLDR
Analysis of the data with the aid of PRESTON'S "octave" method suggests that the population densities of many species of trees in the Amazonian Hylea are less than one individual per hectare. Expand
The Number of Species of Insect Associated with Various Trees
TLDR
The coniferous forest belt is far more extensive in Russia than in Britain and thus pine, spruce, larch and fir (the last three introduced species in Britain) will be comparatively fewer in Russia. Expand
Patterns of communities in the tropics
TLDR
The following general hypothesis seems necessary:species interactions are important and the tropics have a head start on speciation, and the species diversity of the food supply nor the longer breeding season is relevant to bird species diversity. Expand
Evolutionary action of tropical animals on the reproduction of plants
The value of structural characters should be assessed by their role in local reproductive processes. Just as in genetics the abstract species has been replaced by the population, the functionalExpand

TLDR
It is suggested here that the parasites of mammals can provide an effective mechanism for dividing habitats that is relatively independent of the primary characteristics of the competitors. Expand
Plant Host Specificity Among Flower-Feeding Neotropical Drosophila (Diptera: Drosophilidae)
TLDR
An association of the same two distantly related host specific drosophilids in different geographical areas is presumed to have been established in the Pliocene at least, antedating the differentiation of the ancestral Heliconia into five closely related plant species. Expand
THE EVOLUTION AND ECOLOGY OF CLOSELY RELATED SPECIES LIVING IN THE SAME AREA
TLDR
The diversity of both the flora and fauna of natural habitats has frequently been interpreted as the result of the intensity of a struggle for existence between nearly related forms, but there has been considerable controversy about the correct interpretation of field observations in this context.

Reproductive Behavior in the Passifloraceae and Some of Its Pollinators in Central America
TLDR
It is postulated that the selective forces that have led to the timing and movements of the styles and stigmas are those positive advantages generally associated with out-crossing in plants. Expand
Biologies of Three Species of Alydus in Wisconsin
TLDR
The laboratory biologies of the 3 species were very similar, and the use of spittle during cleaning was noted, and also the feeding of nymphs on eggs. Expand
