| 98 | Soil organic matter dynamics in the tabonuco forest, a plantation and a secondary forest in Guzman |
In this project we try to find out the relationship between the primary production and the soil organic carbon fractions. |

| 99 | Herbivory of eight common species at El Verde from 1994 to 1996 |
In seasonal and aseasonal tropical forests, leaf production is often highly synchronous, concentrating herbivore resources in only a few months. As a result levels of herbivory on young... |

| 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... |

| 102 | Leaf miners (Acrocercops sp.) larvae performance on young leaves of Manilkara bidentata |
Manilkara bidentata is attacked by a specialist leaf miner(Acrocercops sp.(microlepidoptera:gracillariidae). More than one larvae can be found per mine within a leaf. The... |

| 103 | Effect of plant density and light availability on leaf damage in Manilkara bidentata |
Variation in herbivory is often associated with plant density and light environment. To determine the effect of these variables on herbivory we studied leaf production and herbivory on saplings,... |

| 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... |

| 105 | Enclosure/exclosure experiments in a montane Puerto Rican stream examining direct and indirect effects of two dominant taxa of atyid (Atyidae) shrimp, Atya lanipes Holthius and Xiphocaris elongata Guerin-Meneville (Shrimp/ Algae/ Oecologia (1993)) |
Freshwater shrimp dominate the faunal biomass of many tropical headwater streams: however, their role in community organization is unclear. Enclosure/exclosure experiments in a montane Puerto... |

| 106 | Effects of biotic (shrimp) and abiotic (discharge) factors on the depositional environment quantified in a montane stream in Puerto Rico. (Shrimp/Algae/Can J. Fish Aquat. Sci. (1994)) |
Effects of biotic (shrimp) and abiotic (discharge) factors on the depositional environment were quantified in a montane stream in Puerto Rico. Electricity was used experimentally to exclude large... |

| 107 | El Verde Grid invertebrate data |
The data set consists of 13 files: (1) abundance data for the walking stick, Lamponius portoricensis, (2) estimates of abundance (Minimum Number Known Alive) for 17 species of terrestrial snails,... |

| 108 | Patterns in soil and physical properties of the Bisley Watersheds 1 and 2 (Big Dig 1988, Big Dig 1990) |
(1) Exchangeable cation concentrations were measured using different soil extracting procedures (fresh soil and air-dried and ground soil) to establish a range of nutrient availability in... |

| 109 | Rio Icacos hyporheic and riparian chemistry |
Hydrologic and chemical characteristics were determined for both riparian and hyporheic subsurface flow along a 100-m reach of a sandy-bottom tributary of the Rio Icacos in the Luquillo... |

| 110 | Spatial Variation of Soil Carbon, Nitrogen and Phosphorus in the Luquillo Experimental Forest (LEF) (LEF_SOIL_CNP) |
Hongqing Wang, a Ph.D graduate student of SUNY-ESF, with the help of many others, took soil samples in 119 locations over the entire Luquillo Experimental Forest (LEF) during the summer of 1998... |
Charles A.S. Hall | Completed |
| 111 | Litterfall in tabonuco (subtropical wet) forest in the Luquillo Experimental Forest, Puerto Rico (MRCE Litterfall data) |
Treatments common to both sites are quarterly fertilization (macro- and micronutrients) and unmanipulated. At El Verde, a third set of plots was subject to a one time removal of litter and woody... |

| 112 | Landslide Removal Experiment vegetation cover and pole touches |
The purpose of this data set is to document recovery of vegetation in removal plots in landslides in the Luquillo Experimental Forest (LEF.) |
Lawrence R. Walker | Completed |
| 113 | Seedling and sapling dynamics of treefall pits and undisturbed florest floor in El Verde, Puerto Rico |
Seedling and sapling dynamics in a Puerto Rican rain forest were compared between forest understory and soil pits created by the uprooting of 27 trees during Hurricane Hugo. No difference in N and... |
Lawrence R. Walker | Completed |
| 114 | Rio Mameyes Diatoms 1998-2000 |
Survey expeditions of the diatoms of Puerto Rico and other Caribbean islands were conducted briefly in the late 1800's and early 1900's,. However, until now no intensive study of changes in... |
Completed | |
| 115 | Short-term disappearance of foliar litter of three tree species native to rain forest of Puerto Rico |
Litter disappearance was examined before (1989) and after (1990) Hurricane Hugo in the... |

| 116 | Bromeliad chemistry at different elevations in the LEF |
Mean concentrations of various nutrients in dried bromeliad leaf and in the coarse, medium and fine portions of debris retained by the bromeliad rosette. |
Barbara A. Richardson | Completed |
| 117 | Bromeliad collection data at different elevations in the LEF |
Collection details of bromeliads collected for invertebrate community and diversity analysis from 4 localities in the LEF. Dates, location, plant size, amounts, pH and temp. of contained water,... |
