- A new species of Pronura from the Luquillo Experimental Forest on Northeastern Puerto Rico is described and illustrated.Pronura yunquensis sp. nov. differs from other Neotropical Pronura in the absence of eyes and can be separated fromother species of the genus by the presence of a head tubercle (De), the displacement of Di1 in Abd IV and the fusedtubercles De+DL in Abd V. A key for identification to American species of Paramanura, Pronura and Paleonura isincluded.AuthorsClaudia M. Ospina-Sanchez, Jose G. Palacios-Vargas, Grizelle GonzalezKeywordsSourceZootaxaYear2021
- A global surge in 'artisanal', smallscale mining (ASM) threatens biodiverse tropical forests and exposes residents to dangerous levels of mercury. In response, governments and development agencies are investing millions (USD) on ASM formalization; registering concessions and demarcating extraction zones to promote regulatory adherence and direct mining away from ecologically sensitive areas. The environmental outcomes of these initiatives are seldom systematically assessed. We examine patterns of mining-related deforestation associated with formalization efforts in a gold-rich region of...AuthorsNora Alvarez-Berrios, Jessica LRoe, Lisa Naughton-TrevesKeywordsSourceEnvironmental Research LettersYear2021
- Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties. Datasets were required, at a minimum, to include abundance or biomass of earthworms at a site. Where possible,...AuthorsSandy M.

- This study analyzes multiyear data recorded by 21 stations along an elevation gradient (0–1045 m a.s.l.) in the Luquillo Mountains on the rainfall and the rainwater chemistry. The totalionic concentration and the rainwater volume exhibited an inverse exponential relationship, withthe correlation coefficients ranging from –0.66 to –0.90. Furthermore, the rainfall tended toincrease with the elevation, although a few stations, owing to their geographical location and theirexposure to the prevailing winds, departed from this trend. The ionic composition also displayedclear seasonality:...AuthorsElvis Torres-Delgado, Grizelle Gonzalez, Ernesto Medina, María M. RiveraKeywordsSourceAerosol and Air Quality ResearchYear2021
- The Puerto Rico Breeding Bird Atlas (PRBBA) project collected and summarized information on the timing of breeding and geographic distribution of 130 breeding bird species on Puerto Rico, and its associated satellite islands and cays. Fieldwork coordinated by the Puerto Rican Ornithological Society (SOPI) involved 344 volunteer observers who contributed to more than 45,500 individual observations of birds from 2004 through 2009. Following standard breeding bird atlas protocol, observers searched for breeding evidence in 479 hexagons while recording bird behavior. Each observed behavior was...AuthorsJessica Castro-Prieto, Joseph Wunderle, Jose A. Salguero-Faria, Sandra Soto-Bayo, Johann D. Crespo-Zapata, William A. GouldKeywordsSourceGen. Tech. Rep. IITF-53.

- The Luquillo Experimental Forest (LEF) has a long history of research on tropical forestry, ecology, and conservation, dating as far back as the early 19th Century. Scientific surveys conducted by early explorers of Puerto Rico, followed by United States institutions contributed early understanding of biogeography, species endemism, and tropical soil characteristics. Research in the second half of the 1900s established the LEF as an exemplar of forest management and restoration research in the tropics. Research conducted as part of a radiation experiment funded by the Atomic Energy...AuthorsJess K. Zimmerman, Tana E. Wood, Grizelle Gonzalez, Alonso Ramirez, Whendee L.

- Within a forest, differences in landform spatial variation (i.e., geomorphic settings: valley, slope, and ridge) could affect the species richness and distribution present at a particular site. Previous studies have confirmed that plant species richness and biomass changes after a hurricane and such values can vary among geomorphic settings. Understory vegetation, including ferns, herbs, climbers, graminoids, and shrubs, accounts for more than two thirds of flora in tropical ecosystems, but there is limited information of the effect of hurricanes on these communities. We evaluated the...AuthorsN.M. Soto-Parrilla, Tamara Heartsill ScalleyKeywordsSourceActa CientificaYear2021
- Streams and rivers of the Luquillo Experimental Forest, Puerto Rico, have been the subject of extensive watershed and aquatic research since the 1980s. This research includes understanding stream export of nutrients and coarse particulate organic matter, physicochemical constituents, aquatic fauna populations and community structure. However, many of the streams and watersheds studied do not appear in standard scale maps. We document recent collaborative and multi-institutional work to improve hydrological network information and identify knowledge gaps. The methods used to delimit and...AuthorsM.C.

- The soil is an important resource for several ecosystem and biosphere processes. Yet, soil biology is challenged with the identification of many and diverse species and to understand the specific role organisms play, how they are organized, and how they respond to changing environmental conditions. Within this context, there is no universal tool or method that can be applied to a comprehensive study of all the soil and litter fauna that can be found across all soil types and environmental conditions around the globe. Thus, the type of sampling system used for any soil investigation must be...AuthorsGrizelle Gonzalez, Maria Fernanda Barberena-Arias, Wei Huang, Claudia M.

- The phylogenetic and functional diversity of microbial communities in tropical rainforests, and how these differ from temperate communities remain poorly described but are directly related to the increased fluxes of greenhouse gases such as nitrous oxide (N2O) from the tropics. Towards closing these knowledge gaps, we analyzed replicated shotgun metagenomes representing distinct life zones from four locations in the Luquillo Experimental Forest (LEF), Puerto Rico. These soils had a distinct microbial community composition and lower species diversity when compared to temperate grasslands or...AuthorsSmruthi Karthikeyan, Luis H. Orellana, Eric R.
