Forest vegetation along environmental gradients in northeastern Puerto Rico

  title={Forest vegetation along environmental gradients in northeastern Puerto Rico},
  author={Peter L. Weaver and William A. Gould},
The Luquillo Mountains in northeastern Puerto Rico rise abruptly from sea level to 1074 m at El Toro Peak in the Luquillo Experimental Forest (LEF) (Fig. 1). The simplest classification of forest types along this gradient recognized moist coastal forest surrounding the mountains, and lower and upper forests within the LEF (Little and Wadsworth 1964). During the 1940s, climax forests along the same gradient from shoreline to mountain summit were described in the Lesser Antilles as follows (Beard… 

Climate variability at multiple spatial and temporal scales in the Luquillo Mountains, Puerto Rico

Puerto Rico is centered on 18°N latitude and 66°W longitude, and serves as a geographic boundary between the Caribbean Sea and the North Atlantic Ocean. Two major mountainous systems on the island,

Short-Term Precipitation and Temperature Trends along an Elevation Gradient in Northeastern Puerto Rico

AbstractAs is true of many tropical regions, northeastern Puerto Rico is an ecologically sensitive area with biological life that is highly elevation dependent on precipitation and temperature.

Lowland extirpation of anuran populations on a tropical mountain

This study confirms the general impressions of amphibian population extirpations at low elevations, and corroborates the levels of threat assigned by IUCN.

Woody debris characterization along an elevation gradient in northeastern Puerto Rico

Woody debris is an ecologically important component of forests; providing habitat for animals and germinating plants, as well as contributing to soil moisture regula-tion and nutrient cycling (Harmon

Research across Latitude , Elevation and Disturbance Gradients : A Review of Forest Studies from Puerto Rico during the Past 25 Years

Progress in understanding changes in soil biology in response to latitude, elevation and disturbance gradients has generally lagged behind studies of above-ground plants and animals owing to

Impacts of a drought and hurricane on tropical bird and frog distributions

During the last few decades, much attention has focused on how global change is affecting the environment and species distributions. Land-use change is still the major cause of species declines

Post-Hurricane Successional Dynamics in Abundance and Diversity of Canopy Arthropods in a Tropical Rainforest

The legacy of canopy gaps created by Hurricane Hugo persisted for at least 19 yr, despite droughts and other hurricanes of various intensities that caused forest damage, reinforces the need to consider historical legacies when seeking to understand responses to disturbance.

Soil biology research across latitude, elevation and disturbance gradients: A review of forest studies from Puerto Rico during the past 25 years

Results of forest soil biology research over the past 25 years in Puerto Rico are summarized as part of a 75th Anniversary Symposium on research of the USDA Forest Service International Institute of Tropical Forestry.

Mercury Sourcing and Sequestration in Weathering Profiles at Six Critical Zone Observatories

Mercury sequestration in regolith (soils + weathered bedrock) is an important ecosystem service of the critical zone. This has largely remained unexplored, due to the difficulty of sample collection

Population, Community, and Metacommunity Dynamics of Terrestrial Gastropods in the Luquillo Mountains: a Gradient Perspective

Population- and community-level attributes of biodiversity changed gradually, and paralleled variation in total gastropod abundance and net primary productivity in general, and similar mechanisms explain both elevational variation and the differences between mixed forest and palm forest transects.



Forest structure and composition in the lower montane rain forest of the Luquillo Mountains, Puerto Rico.

SUMMARY Six groups of three plots stratified by aspect and topography and varying in elevation were used to sample forest structure and tree species composition within the lower montane rain forest

Dwarf Forest Recovery after Disturbances in the Luquillo Mountains of Puerto Rico

Abstract. Dwarf forest in Puerto Rico's Luquillo Mountains varies according to substrate and topography with very short, dense forest growing on exposed, rocky sites. High elevation level sites

Forest recovery in abandoned cattle pastures along an elevational gradient in Northeastern Puerto Rico

A major cause of tropical deforestation has been the conversion of lowland forest into pastures for cattle grazing. We studied forest structure and species composition following abandonment of cattle

Forest structure before and after Hurricane Hugo at three elevations in the Luquillo Mountains, Puerto Rico

Overall, the hurricane altered forest structure so much that forest composition and dynamics could be affected for many years and local variation in hurricane damage can contribute to forest complexity in the Luquillo Mountains.

A Flood Plain Palm Forest in the Luquillo Mountains of Puerto Rico Five Years After Hurricane Hugo 1

This study shows how a periodic disturbance provides long-term opportunities for species invasions and long- term ecosystem response at the patch scale of < 1 ha.

Forest Regeneration in a Chronosequence of Tropical Abandoned Pastures: Implications for Restoration Ecology

During the mid‐1900s, most of the island of Puerto Rico was deforested, but a shift in the economy from agriculture to small industry beginning in the 1950s resulted in the abandonment of

Forest structure and productivity in Puerto Rico's Luquillo Mountains.

The structural and floristic impoverishment of forests and changes in forest dynamics with ascent in the Luquillo Mountains reflect cooler temperatures, fog, and heavier rainfalls that interact to produce saturated soils and retard the mineralization of organic matter.

Landslide disturbance and forest regeneration in the upper Luquillo Mountains of Puerto Rico.

The natural landslide disturbance regime and the major trends in post-landslide succession were studied within a 44-km 2 belt between 530 and 850 m a.s.l. (subtropical lower montane wet forest, sensu

Hurricane damage to a flood plain forest in the Luquillo Mountains of Puerto Rico

Hurricane Hugo caused low to moderate damage to a flood plain forest that was partially protected by its topographic position. Treefalls and the location of damage suggested N to NW wind direction

Forest Plantations in Puerto Rico

Many facets of forest plantation establishment and management have been explored during the 50-year history of the Institute of Tropical Forestry. Little was known until recently about the extent and
