| The general behavior of the tourism sector in Puerto Rico, with its marked seasonality, hints at a close relationship between tourism activities and climate conditions. Even if weather condition is only one of many variables considered by travelling tourists, climate conditions weigh heavily in the majority of the decisions. The effect of climate variability on the environment could be manifested in warmer temperature, heat waves, and changes in the frequency of extreme weather events, such as severe storms and hurricanes, floods, and sea level rise. These conditions affect different sectors of society, among them public health and the economy. Therefore, our research has two main objectives: to establish a tourism climate index (TCI) for Puerto Rico and... |

| Forest transitions (FT) occur when socioeconomic development leads to a shift from net deforestation to reforestation; these dynamics have been observed in multiple countries across the globe, including the island of Puerto Rico in the Caribbean. Starting in the 1950s, Puerto Rico transitioned from an agrarian to a manufacturing and service economy reliant on food imports, leading to extensive reforestation. In recent years, however, net reforestation has leveled off. Here we examine the drivers of forest transition in Puerto Rico from 1977 to 2000 at two subnational, nested spatial scales (municipality and barrio) and over two time periods (1977-1991 and 1991-2000). This study builds on previous work by considering the social and biophysical factors that... |

| The loss of green areas and vegetation in suburban neighborhoods poses short- and long-term consequences associated with environmental changes and socioeconomic decline that can propel such developments to an unsustainable state. We summarize an interdisciplinary investigation aimed at identifying the drivers of green area loss, green cover loss, and quantifying the impact on three inner-ring suburban neighborhoods located along the Rio Piedras watershed in San Juan, Puerto Rico. An inductive approach to social-ecological research was undertaken because it provides a flexible platform for interdisciplinary collaboration on this complex and dynamic subject. The three developments selected for the study were constructed in the mid-20th century under... |

| In the flat littoral of the coast of Puerto Rico (West Indies) at the reef of Cayo Enrique a few Cyclopoida Gnathostoma were collected in colonies of the corallimorpharian Ricordea florida Duch & Mich., which belong to the subfamilies Pterinopsyllinae and Euryteinae. These are the following species: Pterinopsyllus insularis n. sp., Euryte grata n. sp. and Ancheuryte notabilis n. g., n. sp. Pterinopsyllus insularis differs from the till now known species of the genus by the number of segments of the first antenna, as well as in the form and armature of P 5. A differential diagnosis and a key for the genus is added. Because of striking differences in the structure of antenna 1 and P 5, a new genus Pterinopsyllotus is established for Pterinopsyllus... |

| Abstract: This paper presents a model of location decisions of a multi-period, finite-life, utility maximizing individual and an empirical hazard rate analysis of return migration for Puerto Rican born males who worked in the United States during the 1980s. A potential migrant is assumed to consume leisure, purchased goods, and local amenities and to be retired in his final period of life. We show that it is optimal for him to migrate in the first period or to never migrate. Given that migration occurs, return migration is likely when he retires from the labor market. The reason is local amenities, including nearness to family, friendly culture, pleasant climate, and familiar places, which are complementary with leisure, weigh heavily in consumption... |
