| 31 | Bisley 40 X 40 grid vegetation and site characteristics |
Relationships between landforms, soil nutrients, forest structure, and the relative importance of different disturbances were quantified in two subtropical wet steepland watersheds in Pueno Rico.... |

| 57 | Tree damage by Hurricane Hugo on the Luquillo Forest Dynamics Plot (LFDP), Puerto Rico |
Hurricane Hugo struck the Caribbean national forest in September 1989. Files LFDP_HURRDAM.TXT and LFDP_HURRDAMa.TXT contain data on the damage to trees caused by the hurricane collected by Mr. R.... |

| 100 | El Verde Coffee Plantation permanent plot vegetation sampling |
Permanent plot data is expected to show (1) rapid increases in percent cover and tree stem density, and (2) rapid turnover from early to late successional plant species. Plant-plant competition... |

| 135 | Recovery of a tropical stream after a harvest-related chlorine poisoning event |
1. Harvest-related poisoning events are common in tropical streams, yet research on stream recovery has largely been limited to temperate streams and generally does not include any measures of... |

| 40 | Regeneration after Hurricane Hugo woody species > 1m tall (9ha grid, El Verde) Percent cover below 3m (9 ha grid, El Verde) |
Purpose was to document vegetation damage and recovery following Hurricane Hugo. |
Completed | |
| 37 | Regeneration after Hurricane Hugo, woody species > 10 cm tall (9Ha grid, El Verde) (9Ha Plots Small Data Set) |
Purpose is to document vegetation damage and recovery following Hurricane Hugo |

| 104 | Experimentally manipulated biota over a 30-40d period in two streams with distinctly different macrobiotic (Shrimp/Organic Matter/Ecology (1999)) |
Here we test the hypothesis that differences in macrobiotic assemblages can lead to differences in the quantity and quality of organic matter in benthic depositional environments among streams in... |
Catherine Pringle | Completed |
| 30 | Frog grid data (Bisley) |
Population estimates from 1987 to 1995 are reported for the terrestrial anuran, Eleutherodactylus coqui, from four long-term study plots in the Luquillo Experimental Forest of northeastern Puerto... |
Lawrence L. Woolbright | Completed |
| 91 | Earthworms in tropical tree plantations and secondary forests |
We compared patterns of earthworm abundance and species composition in tree plantations and secondary forests of Puerto Rico. Tree plantations included pine (Pinus caribaea Morelet) and mahogany (... |
Xiaoming Zou | Completed |
| 141 | Neritina snails hierarchical distribution |
This data set includes N. virginea densities and sizes relative to streambed substrate type, water depth, and habitat type in a low land reach in RÃo Mameyes near PR Route 3 bridge, and presence... |
Juan Felipe Blanco | Completed |
| 42 | Bisley Grid Habitat data 1994, 1999 |
The data set consists of one file containing data from the summers of 1994 and 1999. Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (... |

| 17 | Minimum temperature at El Verde Field Station, Rio Grande, Puerto Rico since 1975 |
Daily emperature has been measured at the El Verde Field Station since 1975 (see methods). Monthly averages have been calculated. Lowest average values for minimum temperature were recorded from... |

| 45 | Frog spatial distribution data (El Verde + Bisley) |
Most Puerto Rican Eleutherodactylus are terrestrial frogs that breed for prolonged periods of time in more or less continuous habitat. Because their life cycle lacks a free living... |

| 8 | Canopy gap survey at El Verde |
The survey of gaps at El Verde covers about 35 ha, including the 9 ha grid. We defined a treefall gap at El Verde as a hole in the forest canopy extending down to an average height of about 3 m... |

| 139 | Indirect upstream effects of dams: consequences of migratory consumer extirpation in Puerto Rico |
Large dams degrade the integrity of a wide variety of ecosystems, yet direct downstream effects of dams have received the most attention from ecosystem managers and researchers. We investigated... |

| 22 | Cecropia growth at El Verde gaps |
While doing the survey of gaps at El Verde the number and height of Cecropia saplings found in gaps where recorded. Since this species is mostly restricted to gaps, an estimate of the total... |
Nicholas Brokaw | Completed |
| 76 | Frog abundance infertilization plots |
Population estimates and body sizes of E. coqui were collected on fertilization, litter removal, and control plots. |
Lawrence L. Woolbright | Completed |
| 46 | Elevation at grid points on the Luquillo Forest Dynamics Plot (LFDP) |
