This study examined how different rainfall regimes affect a set of leaf functional traits related to plant stress and forest structure in tropical dry forest (TDF) species on limestone substrate. One hundred fifty eight individuals of four tree species were sampled in six ecological sites in south Florida and Puerto Rico, ranging in mean annual rainfall from 858 to 1933 mm yr-1. Leaf nitrogen content, specific leaf area (SLA), and N:P ratio of evergreen species, but not deciduous species, responded positively to increasing rainfall. Phosphorus content was unaffected in both groups. Canopy height and basal area reached maxima of 10.3 m and 31.4 m2 ha-1, respectively, at 1168 mm annual rainfall. Leaf traits reflected soil properties only to a small extent. This led us to the conclusion that water is a major limiting factor in TDF and some species that comprise TDF ecosystems are limited by nitrogen in limestone sites with less than ~1012 mm rainfall, but organismal, biological and/or abiotic forces other than rainfall control forest structure in moister sites.

El cartel serigráfico del proyecto de carteles del Taller de Cinema y Gráfica de Parques y Recreo Público se utilizó como medio para educar e insertar a las grandes masas dentro de las reformas coloniales ocurridas como consecuencia de la entrada de Estados Unidos a la Segunda Guerra Mundial y readiestrar a la población puertorriqueña, entonces compuesta por campesinos, para servir como mano de obra barata y dócil al proyecto colonial y a los beneficiarios del proyecto de industrialización de la posguerra. Se ha dicho en innumerables ocasiones que el camino al infierno está repleto de buenas intenciones; este es el relato de un viaje de ida. Los carteles de la División de Cinema y Gráfica de Parques y Recreo Público mantienen desde el origen varios elementos inquietantes de lo que se podría denominar como la política de reconstrucción de una colonia, de un territorio objeto de la sujeción/subyugación por parte de otro país, y presentarlo como un objetivo plausible, de consideración y cumplimiento con los derechos humanos fundamentales...

The effectiveness of antiretroviral therapy (ART) transformed the pediatric HIV epidemic. The disease changed significantly over the course of three decades: while early in the epidemic it was almost always fatal, it has become a chronic condition. This study examined how perinatally-infected youth experience the impact of HIV in their lives. A qualitative study using interpretative phenomenological analysis (IPA) was conducted. Twenty in-depth interviews were carried out among 12 women and 8 men aged 18 to 30 years in Puerto Rico. These were conducted in Spanish, audio-recorded, transcribed and translated into English. While narrating their experiences, participants were interpreting what the situation meant to them and how they make sense of it. Three topics emerged: (1) perception and response to treatment and illness, particularly their lived experiences with ART; (2) disclosure experiences; and (3) family matters. Most participants challenged their therapy, in most cases to force their caregivers to disclose their status. Problems with adherence were attributed to busy schedules or forgetfulness. Participants experienced the disfiguring adverse effects of ART, which they endured for years without being informed that ART was the cause of these. Participants’ experiences with disclosure demonstrated the importance of validating them as individuals capable of managing their health. The paternalistic approach of withholding their diagnosis to spare them suffering resulted in increased anxiety. Participants acknowledged the difficulties of revealing their HIV status to their partners. They referred to family and friends as essential in coping with HIV. However, some encountered discrimination and stigma within their families. Participants who had suffered the loss of their parents found other parental figures such as adoptive parents or other family members. Most participants expressed a desire to have children. Perinatally HIV-infected youth will require health services for the rest of their lives. The adult health care into which they transition should consider their needs and journey. Services should consider including family members. This study underscores the need for improved access to mental health services. It is also essential to transcend medical treatment and develop a broader perspective of health care. Health care services should include reproductive decision-making counselling services.
