Specialised natural enemies maintain forest diversity by reducing tree survival in a density‐ or distance‐dependent manner. Fungal pathogens, insects and mammals are the enemy types most commonly hypothesised to cause this by: Because natural enemies may reduce establishment near adult mahogany trees (Norghauer et al., a), we intentionally positioned our seed plots far from adult seed shadows.

According to the Janzen–Connell model, high mortality of seeds and seedlings in proximity to conspecific adults can help maintain species diversity in tropical forests. Using a natural population of big-leaf mahogany (Swietenia macrophylla King), we tested the model’s mechanism by examining seed predation and juvenile recruitment in the forest understory and in treefall gaps in the.

A growth function for the mahogany seedlings was derived by linear regression of seedling height at each measurement ().The regression equation was (3) H m = A + where H m is the mean height and A is the age in years.
The regression was highly significant and explained most of the variation in the data (p. Seeds The Ecology of Regeneration in Plant Communities (Revised) Focal tree species and mahogany herbivores. Big-leaf mahogany (hylla, Meliaceae), is a self-compatible, long-lived perennial tree distributed from southern México to Bolivia .Plants are monoecious, produce unisexual flowers , and fruits are woody capsules containing wind-dispersed seeds .This species also produces extra-floral nectaries (EFN’s) which are located at the base of.

Not shown because of too small a sample size is introduced small-leaf mahogany (S. mahagoni), which had an average (± SE) of %± (n = 4 plots. Invasive species have a long history of causing damage to forests in Asia and the Pacific, and a variety of infestations are currently having significant impacts in a number of countries.
The damage caused by invasive species imposes enormous costs on the forests of the region in terms of ecological destruction, economic losses and detrimental social effects. as have been suggested for example for big-leaf mahogany (Grogan ). Seed survival may be reduced in gaps relative to the understory, but survival and growth of juveniles may be enhanced due to increased light levels.
The influence of canopy gaps on density and distant-dependent attacks by natural enemies and on mortality remains largely. In each case over-abundant deer, when deprived of their natural enemies, have made it impossible for deer food plants to survive and reproduce.
Beech, maple, and yew in Europe, ground hemlock and white cedar in the eastern states, mountain mahogany and cliff-rose in the West, are deer foods threatened by artificialized deer.

Aldo Leopold, perhaps best known for his revolutionary and poignant essays about nature, was also an eloquent advocate during the s and s of the need to maintain wolves and other large carnivores in forest and range ecosystems.
He indicated that their loss set the stage for ungulate irruptions and ecosystem damage throughout many parts of the United States. We have synthesized the.

Abstract: This book chronicles change in the natural world of the Colorado River as it flows through the Grand Canyon. The authors discuss pre-dam conditions and the effects damming the river has had on natural conditions and processes.Trees known to support PSHB include box elder, big leaf maple, California sycamore, willows, cottonwoods, and several California oaks.
The insect-fungi combinations threaten more than a third of trees in the urban forests in southern California, with a cost for the trees’ removal and replacement estimated at $36 billion.
