Title: Study of the Vascular Flora of the La Olimpia Forest Reserve
Authors: Abeliz Rosado-martinez (PCUPR), Zheidyleen Massó Rodríguez (PCUPR)
Abstract
Forest areas in Puerto Rico have increased during the past 60 to 70 years. Many of these forests are
spontaneous forests that have emerged after the abandonment of agriculture or animal husbandry.
Although there are publications about their recovery, little is known about the patterns and recovery
processes of these forests. This research focuses on succession processes after the abandonment of
agricultural land. The "Bosque Escuela La Olimpia", which comprises some 60 acres, is located in the
central mountainous area in the Saltillo neighborhood in Adjuntas. The elevation ranges are between
300 and 1,000 meters above sea level. The study was conducted in quadrants of 400m2, which were
selected randomly and without replacement based on the altitudinal ranges. In each quadrant, all trees
with a diameter at breast height (DBH) of at least 5 cm were sampled. The trees were identified by
species and according to their status: native, naturalized, endemic, rare or in danger of extinction. We
consider the lower slopes as highly disturbed areas and the high slopes as areas of mature vegetation.
The low areas of the mountains are composed mainly of herbaceous plants, such as herbs, vines and
ferns, but there are also some cultivated species such as citrus, legumes and passion plants. Of the tree
species so far sampled, a total of 24 species have been identified. Of these, 10 species are naturalized,
11 species are native and 3 species are endemic. The information of the flora and data obtained in this
research allows us, and will allow the scientific community to better understand the processes of
ecological succession in secondary forests, in addition to serving as a basis to create models of forest
recovery in Puerto Rico.

Title: Preliminary Results on the Arecibo Pisces-Perseus Supercluster Survey

de Andalucia, Granada, Spain), Rebecca Koopmann (Union College, Schenectady, NY,

Abstract
The Arecibo Pisces-Perseus Supercluster Survey (APPSS) aims to exploit the Baryonic Tully-Fisher
Relation to derive distances and peculiar velocities of galaxies in and near the main ridge of the Pisces-
Perseus Supercluster (PPS), one of the most prominent features of the Cosmic Web in the nearby
Universe. The sample of galaxies contains ~ 600 sources in the low-mass range (8 6. With this sample,
the nature of the galaxy population in and around the PPS will be investigated. The HIMF to log MHI ~
8.0 along the PPS filament will be measured and using the Tully-Fisher relation it will be possible to
make a robust measurement of the infall and backflow onto the filamentary structure.
APPSS is collaborative project between more than 10 Undergraduate ALFALFA Team institutions in
which each group contributes to the analysis of a subset of the HI PPS data. In this poster, we will
present the contributions of the U.P.R. team to the APPSS project. We will show the procedure used for
the Arecibo HI data analysis, including some examples, and will show our preliminary
results.
This work has been supported by NSF grants AST-1211005, AST-1637339 and AST-1637276.

Title: Report on the Observation of Binaries in 2013: Humacao University Observatory

Abstract
This is a report on observations of position angle and separation of binary stars of the year 2013 from
the Humacao University Observatory. The stars analyzed totaled 62; they were imaged at the NURO 31
inch telescope in Flagstaff, Arizona in June 2013. The images were analyzed at the Humacao Observatory
of the University of Puerto Rico.

Title: Separation and position angle measurement of binary star systems taken from
Washington Double Star Catalog

Abstract
We report on measurements of position angle and separation of a group of binary pairs. The data was
obtained using the NURO Telescope at Anderson Mesa location of Lowell Observatory, 20 miles east of
Flagstaff, Arizona in 2014. We gathered the data using 2K x 2K CCD camera, -NASACAM- at the prime
focus of the 31 imch telescope. The data was transfered and analized at the University of Puerto Rico at
Humacao Observatory by undergraduate students undertaking research projects.
