Aaron S Kaulfus, Udaysankar S Nair, Christopher D Holmes, William M Landing
We analyze the effect of precipitation type on mercury wet deposition using a new database of individual rain events spanning the contiguous United States. Measurements from the Mercury Deposition Network (MDN) containing single rainfall events were identified and classified into 6 precipitation types. Mercury concentrations in surface precipitation follow a power law of precipitation depth that is modulated by precipitation system morphology. After controlling for precipitation depth, the highest mercury deposition occurs in supercell thunderstorms with decreasing deposition in disorganized thunderstorms, quasi-linear convective systems (QLCS), extratropical cyclones, light rain and land-falling tropical cyclones...

Animal behavior and energy expenditure often vary significantly across the landscape, and quantifying energy expenditure over space and time provides mechanistic insight into ecological dynamics. Yet, spatiotemporal variability in energy expenditure has rarely been explored in fully aquatic species such as fish. Our objective was to quantify spatially explicit energy expenditure for a tropical marine teleost fish, bonefish (Albula vulpes), to examine how bonefish energetics vary across landscape features and temporal factors...

In Puerto Rico, the microbial diversity of the thermal spring (ThS) in Coamo has never been studied using metagenomics. The focus of our research was to generate a metagenomic library from the ThS of Coamo, Puerto Rico and explore the microbial and functional diversity. The metagenomic library from the ThS waters was generated using direct DNA isolation. High molecular weight (40 kbp) DNA was end-repaired, electro eluted and ligated into a fosmid vector (pCCFOS1); then transduced into Escherichia coli EPI300-T1R using T1 bacteriophages...

BACKGROUND: Total immunoglobulin E (IgE) is a therapeutic target in allergic diseases. DNA methylation in white blood cells (WBCs) was associated with total IgE in an epigenome-wide association study (EWAS) of Caucasians. Whether DNA methylation of eosinophils explains those findings is insufficiently understood. METHODS: We tested for association between genome-wide DNA methylation in WBCs and total IgE in two studies of Hispanic children: the Puerto Rico Genetics of Asthma and Lifestyle Study (PR-GOAL, n = 306) and the Genes-environments and Admixture in Latino Americans (GALA II, n = 573)...

On December 1, 2015, the Puerto Rico Department of Health (PRDH) was notified by a local hospital of a suspected human rabies case. The previous evening, a Puerto Rican man aged 54 years arrived at the emergency department with fever, difficulty swallowing, hand paresthesia, cough, and chest tightness. The next morning the patient left against medical advice but returned to the emergency department in the afternoon with worsening symptoms. The patient's wife reported that he had been bitten by a mongoose during the first week of October, but had not sought care for the bite...

The introduction and rapid spread of Zika virus (ZIKV) across the Western Hemisphere have posed a risk of infection to Military Health System (MHS) beneficiaries. The associated consequences of infection and the dynamics of transmission may place a unique burden on military personnel, their dependents, and the MHS. This article summarizes the impact of ZIKV transmission on MHS beneficiaries between 1 January and 30 November 2016. Cases were identified from a variety of sources, including direct reporting from the services, extraction of laboratory data, and data from the Defense Medical Surveillance System (DMSS) Reportable Medical Events database...

: Vaccination is considered the most effective preventive means for influenza control. The development of a master virus with high growth and genetic stability, which may be used for the preparation of vaccine viruses by gene reassortment, is crucial for the enhancement of vaccine performance and efficiency of production. Here, we describe the generation of a high-fidelity and high-growth influenza vaccine master virus strain with a single V43I amino acid change in the PB1 polymerase of the high-growth PR8 master virus...

We quantified long-term successional trajectories of canopy arthropods on six tree species in a tropical rainforest ecosystem in the Luquillo Mountains of Puerto Rico that experienced repeated hurricane-induced disturbances during the 19-yr study (1991-2009). We expected: 1) differential performances of arthropod species to result in taxon- or guild-specific responses; 2) differences in initial conditions to result in distinct successional responses to each hurricane; and 3) the legacy of hurricane-created gaps to persist despite subsequent disturbances...

Puerto Rico detected the first confirmed case of chikungunya virus (CHIKV) in May 2014 and the virus rapidly spread throughout the island. The invasion of CHIKV allowed us to observe Aedes aegypti (L.) densities, infection rates, and impact of vector control in urban areas using CDC autocidal gravid ovitraps (AGO traps) for mosquito control over several years. Because local mosquitoes can only get the virus from infectious residents, detecting the presence of virus in mosquitoes functions as a proxy for the presence of virus in people...

Recent theoretical work suggests that two ineffective control agents can provide effective biological control when coupled together. We explore the implications of this work with the system of coffee leaf rust (CLR), caused by the fungal agent Hemileiae vastatrix, and two of its natural enemies, a fungal pathogen (Lecanicillium lecanii) and a spore predator (Mycodiplosis hemileiae). Here we report on comparative surveys of the CLR and its two natural enemies in Mexico, where the CLR has been at epidemic status since 2012, and Puerto Rico, where the CLR is present but has not reached epidemic densities...

It is reported that the rates of perinatal depressive disorders are high in ethnic minority groups from non-English speaking countries. However, very few studies have compared the prevalence of positive screening for postpartum depression (PPD) in minority communities living in an inner city. The goal of this study is to determine the prevalence and the predictors of positive screening for postpartum depression in minority parturients in the South Bronx. The study is a chart review of 314 minority parturients, Black or Hispanic, screened for postpartum depression using the Edinburgh Postnatal Depression Scale (EPDS) tool...

ABSTRACT: When close relatives mate, offspring are expected to suffer fitness consequences due to inbreeding depression. Inbreeding has previously been quantified in two ways: using a sufficiently large panel of markers or deep and complete pedigrees over several generations. However, the application of both approaches is still limited by the challenge of compiling such data for species with long generation times, such as primates. Here, we assess inbreeding in rhesus macaques living on Cayo Santiago (Puerto Rico), a population genetically isolated since 1938, but descendant of a large set of presumably unrelated founders...

BACKGROUND: Little is known about the joint effects of maternal asthma and maternal depression on childhood asthma. OBJECTIVE: To examine whether maternal depression and maternal asthma lead to greater risk of childhood asthma than maternal asthma alone. METHODS: Cross-sectional studies of children (6-14 years old) in San Juan, Puerto Rico (n = 655) and Sweden (n = 6,887) were conducted. In Puerto Rico, maternal depressive symptoms were defined using the Center for Epidemiologic Studies Depression Scale (CES-D) questionnaire...
