Capacidad de carga y efectos del nivel de protección en tres AMPs de las Islas Baleares (Mediterráneo Noroccidental)

The monitoring of fisheries target species in three marine protected areas (MPAs) located in the NW Mediterranean provided important conclusions on management effects. The abundance, occurrence and biomass of large fish showed consistent and growing trends inside the MPAs. Fish diversity was also favoured by protection. Nevertheless, spatial variance of these indicators at a medium scale was often of the same order as that caused by time between different protection levels. The carrying capacity was determined for the first time in western Mediterranean MPAs in five out of six sites studied, and in all cases it was achieved within the first five years of protection. The observed values indicate that the system of the studied MPAs is representative of the general coastal environment of the Balearic Islands, but is far from the potential of other MPAs which are considered as hot spots in other localities. Likewise, this study shows that partially protected areas can also be fairly effective if their habitats fit with those required by target species and fishing modalities are suitably regulated or banned.El seguimiento de especies de peces vulnerables a la pesca en 3 AMPs del Mediterráneo Occidental ha permitido extraer conclusiones importantes sobre los efectos de la gestión. La abundancia y ocurrencia de peces grandes así como la biomasa presentaron patrones temporales consistentes y crecientes en las AMPs. Conjuntamente al incremento de biomasa, la diversidad de peces también aumentó con la protección. Sin embargo, la varianza de estos indicadores a mediana escala espacial fue a menudo del mismo orden que la producida por el tiempo y el nivel de protección. La capacidad de carga se ha establecido por primera vez en AMPs del Mediterráneo Occidental en 5 de los 6 sitios estudiados. En todos los casos esta situación se alcanzó dentro de los primeros 5 años de protección. Los resultados indican que el sistema de AMPs estudiado es representativo de la mayor parte de las costas de Baleares pero que está lejos del potencial de otras AMPs consideradas como hot spots en otros enclaves geográficos. Asimismo, este trabajo pone de manifiesto que las áreas de reserva parcial pueden ser muy efectivas si su hábitat se ajusta al de las especies que quieren protegerse y si las modalidades de pesca restringidas o prohibidas son las adecuadas

Exploring Barriers to Exercise among Adolescents at the Burlington Boys and Girls Club

Introduction: The Boys and Girls Club of Burlington (BGCB) is a non-profit that holds after-school activities for adolescents, including music, art, technology, and sports. The BGCB has struggled to encourage physical activity (PA) among many participants. We designed our study to identify deterrents to PA, as well as possible ways to improve participation.https://scholarworks.uvm.edu/comphp_gallery/1066/thumbnail.jp

Heroin Use and Sex: Some Patterns in Miami-Dade County, Florida

Much of the literature on heroin and opioid addiction holds that regular, long-term users of heroin and other opioids lose interest in sex as their drug using careers lengthen. Analysis of self-reports collected from IDUs in two cross- sectional surveys on patterns of risk behavior in Miami-Dade County, Florida, reveals that large proportions of IDUs report using heroin before or during sex across a wide range of self-injection experience, from as little as twelve months to over 40 years. One half or more of respondents to both surveys reported using heroin in their recent sexual experiences, with similar proportions reported by both males and females. The same IDUs, however, tend not to report using prescription painkillers before or during sex. This finding indicates that co-occurring risk behavior related to both sexual behavior and heroin use may be more prevalent among long-term IDUs than previous literature has suggested

Comparative genomics of drug‑resistant strains of Mycobacterium tuberculosis in Ecuador

Background: Tuberculosis is a serious infectious disease affecting millions of people. In spite of efforts to reduce the disease, increasing antibiotic resistance has contributed to persist in the top 10 causes of death worldwide. In fact, the increased cases of multi (MDR) and extreme drug resistance (XDR) worldwide remains the main challenge for tuberculosis control. Whole genome sequencing is a powerful tool for predicting drug resistance‑related variants, studying lineages, tracking transmission, and defining outbreaks. This study presents the identification and characterization of resistant clinical isolates of Mycobacterium tuberculosis including a phylogenetic and molecular resistance profile study by sequencing the complete genome of 24 strains from different provinces of Ecuador. Results: Genomic sequencing was used to identify the variants causing resistance. A total of 15/21 isolates were identified as MDR, 4/21 as pre‑XDR and 2/21 as XDR, with three isolates discarded due to low quality; the main sub‑lineage was LAM (61.9%) and Haarlem (19%) but clades X, T and S were identified. Of the six pre‑XDR and XDR strains, it is noteworthy that five come from females; four come from the LAM sub‑lineage and two correspond to the X‑class sub‑lineage. A core genome of 3,750 genes, distributed in 295 subsystems, was determined. Among these, 64 proteins related to virulence and implicated in the pathogenicity of M. tuberculosis and 66 possible pharmacological targets stand out. Most variants result in nonsynonymous amino acid changes and the most frequent genotypes were identified as conferring resistance to rifampicin, isoniazid, ethambutol, para‑aminosalicylic acid and streptomycin. However, an increase in the resistance to fluoroquinolones was detected. Conclusion: This work shows for the first time the variability of circulating resistant strains between men and women in Ecuador, highlighting the usefulness of genomic sequencing for the identification of emerging resistance. In this regard, we found an increase in fluoroquinolone resistance. Further sampling effort is needed to determine the total variability and associations with the metadata obtained to generate better health policies

Temporal dynamics and role of benthic habitat for the Mediterranean slipper lobster Scyllarides latus in a National Park

Populations of large large decapods have diminished due to intense fishing pressure and habitat modification along the widely inhabited coast. During the last decade some of the well established marine protected areas (MPAs) in the Western Mediterranean have led to growing densities of one of the most sought after large decapods, the slipper lobster Scyllarides latus (Latreille, 1803). A four year monitoring study was conducted to assess seasonal dynamics and habitat preference of S. latus in the Cabrera Archipelago National Park. Sampling was carried out through underwater visual census on rocky habitats at 0 - 50 m depth. The species may be found in caves, under boulders, and on walls and slopes at depths of up to 35 m, showing a preference for caves at 5 to 20 m depth. These hábitats provide diverse shelter types that are used during the daily period of trophic inactivity. S latus has a marked seasonality with highest densities occurring in late spring, and they disappear almost entirely from rocky coastal habitats in mid-summer. Knowledge of the preferred habitats and spatial pattern of the species is needed for implementing appropriate management schemes to stimulate their recover
