Elevational gradients of walking stick (Lamponius portoricensis) abundance

General Information
Data Package:
Local Identifier:knb-lter-luq.195.68
Title:Elevational gradients of walking stick (Lamponius portoricensis) abundance
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Abundance data were collected for Lamponius portoricensis from a mixed forest transect and from a palm dominated transect set along an elevational gradient in the Sonadora watershed. Each transect ranged from 300 m to 1000 m in elevation, with elevational strata located at 50 m intervals and 10 plots per stratum. No palm dominated forest could be located at 700 m in the watershed, resulting in 15 strata (150 plots) along the mixed forest transect and 14 strata (140 plots) along the palm forest transect.
The data set includes 3 files that contain abundance data for walking sticks (Lamponius portoricensis) along an elevational gradient within the Sonadora River watershed. Two files (1 and 2) contain data from the mixed forest transect but differ in the year during which they were collected (2007 and 2008). The third file (3) contains data from a palm forest elevational transect from 2008, for which all sites were located in palm dominated forest in the same watershed. Note: Plots at 250 m of elevation were only sampled during 2007, no palm dominated forest could be located at 750 m of elevation; that elevation is omitted from the palm transect.

Data Policies

LTER Network Data Access Policy, Data Access Requirements, and General Data Use Agreement
approved by the LTER Coordinating Committee April 6, 2005

Long Term Ecological Research Network Data Access Policy

The LTER data policy includes three specific sections designed to express shared network policies regarding the release of LTER data products, user registration for accessing data, and the licensing agreements specifying the conditions for data use.

LTER Network Data Release Policy

Data and information derived from publicly funded research in the U.S. LTER Network, totally or partially from LTER funds from NSF, Institutional Cost-Share, or Partner Agency or Institution where a formal memorandum of understanding with LTER has been established, are made available online with as few restrictions as possible, on a nondiscriminatory basis. LTER Network scientists should make every effort to release data in a timely fashion and with attention to accurate and complete metadata.

Data[current-user:created]

There are two data types:

Type I – data are to be released to the general public according to the terms of the general data use agreement (see Section 3 below) within 2 years from collection and no later than the publication of the main findings from the dataset and,

Type II - data are to be released to restricted audiences according to terms specified by the owners of the data. Type II data are considered to be exceptional and should be rare in occurrence. The justification for exceptions must be well documented and approved by the lead PI and Site Data Manager. Some examples of Type II data restrictions may include: locations of rare or endangered species, data that are covered under prior licensing or copyright (e.g., SPOT satellite data), or covered by the Human Subjects Act. Researchers that make use of Type II Data may be subject to additional restrictions to protect any applicable commercial or confidentiality interests.

While the spirit of this document is to promote maximum availability for ecological data in either Type I or II status, there are criteria by which priority for data release may be determined. Primary observations collected for core research activities directly supported by LTER research must receive the highest priority for data release. Data collected by other sources to which LTER supported research has added value is also a high priority Other types of data including non-LTER data that was acquired for LTER research, student thesis data, schoolyard LTER data, or legacy data that already suffer from inadequate documentation or format obsolescence may be ranked a lower priority by a site with justifications provided in their data management policy. Finally, some data may be determined of lowest priority for archiving on the grounds that they are interim data that led to final products that carry the scientific value. These might include data files created during stages within an analytic workflow, raw or replicate data values that were subsequently aggregated or processed for release, or individual outputs from stochastic models.

Metadata

Metadata documenting archived/online data sets of all types listed above will be made available when, or before, the dataset itself is released according to the terms above.
All metadata will be publicly available regardless of any restrictions on access to the data.
All metadata will follow LTER recommended standards and will minimally contain adequate information on proper citation, access, contact information, and discovery. Complete information including methods, structure, semantics, and quality control/assurance is expected for most datasets and is strongly encouraged.
LTER Network Data Access Requirements

The access to all LTER data is subject to requirements set forth by this policy document to enable data providers to track usage, evaluate its impact in the community, and confirm users' acceptance of the terms of acceptable use. These requirements are standardized across the LTER Network to provide contractual exchange of data between Site Data Providers, Network Data Providers, and Data Users that can be encoded into electronic form and exchanged between computers. This will allow direct access to data via a common portal once these requirements have been fulfilled. The following information may be required directly or by proxy prior to the transference of any data object:

Registration

1. Name

2. Affiliation

3. Email Address

4. Full Contact Information

Acceptance of the General Public Use Agreement or Restricted Data Use Agreement, as applicable.
A Statement of Intended Use that is compliant with the above agreements. Such statements may be made submitted explicitly or made implicitly via the data access portal interface.

Methods and protocols used in the collection of this data package
Description:

Paired elevational (strata) transects (300 m to 1000 m) in the Sonadora River watershed were sampled at 50 m intervals to decouple underlying environmental gradients (abiotic variation and vegetational variation) that are associated with changes in elevation and that are hypothesized to structure animal communities. One transect (mixed forest) reflected changes in abiotic and biotic conditions, including forest type (i.e., tabonuco, palo colorado, and elfin forests), whereas the second transect reflected changes in environmental conditions but not forest type, as its constituent plots were all located within palm dominated forest. Each stratum from the mixed forest transect was paired with a stratum in palm forest. In the mixed forest transect, plots were arranged in a 0.1 ha rectangle (50 m by 20 m) comprising 10 circular plots (3 m radius) configured in 2 parallel rows, each containing 5 evenly-spaced plots with 10 m spacing between plot centers. Rectangular strata were aligned with their long axes perpendicular to the Sonadora River. This transect is the same as used in Barone et al. (2008). Because the elevational distribution and size of palm forest patches were variable, palm forest strata were located within 1 km of the corresponding stratum in mixed forest, and always within the Sonadora watershed. By necessity, the configuration of plots within strata of palm forest was more variable than that in mixed forest. Nonetheless, plots were always contiguous, with a maximum distance between centers of the most distant plots being less than 58.3 m (mean, 43.6 m; standard deviation, 6.07m), comparable to the situation along the mixed forest transect, where 41.2 m was the maximum distance between plot centers. Walking sticks at each plot were sampled 4 times during the summer of 2007 (wet season) from the mixed forest transect and 3 times during the summer (wet season) of 2008 from the mixed forest and palm forest transects. Sampling was conducted at night (2000-0400 h). Each time a plot was surveyed, 2 people searched all available surfaces (e.g., soil, litter, rock cover, vegetation, debris) up to a height of approximately 3 m for 15 minutes or until all substrates had been completely searched, whichever was longer. Sampling was not repeated at any one elevation until after the entire gradient was sampled.
