Multispecies mass mortality in the Beagle Channel associated with paralytic shellfish toxins.

The Beagle Channel is a Subantarctic semi-estuarine environment at the southern tip of South America, where intoxication events associated with harmful algal blooms have been reported since 1886, including a world record in toxicity due to Alexandrium catenella in 1992. Toxic algae affect public health and ecosystem services, particularly mussel aquaculture and fisheries management. During the austral summer of 2022, an intense bloom of A.

Who let the young-of-the-year (YOY) up? The pelagic habitat as a nursery and feeding ground area for the YOY Argentine hake Merluccius hubbsi Marini, 1933.

The young-of-the-year (YOY) Argentina hake Merluccius hubbsi remained at particular distances off the seabed at pelagic habitat, in a nursery area located in the San Jorge Gulf off south-western Atlantic. Older specimens were daylight distributed near the bottom in the demersal habitat. In this paper the authors show that the pelagic habitat is favourable for YOY hake compared to the surrounding demersal habitat by decreasing the probability of encounter with larger hake protecting the YOY against conspecific predation, and providing a better food supply.

Using Syndemics Theory to Examine HIV Sexual Risk Among Latinx Men Who Have Sex with Men in Philadelphia, PA: Findings from the National HIV Behavioral Surveillance.

Latinx men who have sex with men (MSM) continue to be disproportionately impacted by HIV/AIDS. Identifying the role of multiple syndemic factors associated with sexual risk behaviors is imperative in order to develop effective prevention and treatment strategies. Cross-sectional data for this study were derived from three cycles of the Philadelphia portion of the National HIV Behavioral Surveillance System.

Bridging the Gap Between Micro and Macro Practice to Address Homelessness in the U.S.-Mexico Border Region: Implications for Practitioners and Community Stakeholders.

Research and scholarship efforts continue to promote the integration of micro and macro practice in social work practice and education. Despite this, scholarship has documented persistent challenges in the fluid integration between the domains of micro-level service provision and macro-level social change efforts in practice and academic programs. This paper outlines a successful bridge between the micro-macro divide in the form of community-engaged practice to address homelessness and social work education in the U.

A couple-based HIV prevention intervention for Latino men who have sex with men: study protocol for a randomized controlled trial.

Background: Latino men who have sex with men (MSM) experienced a 13% increase in HIV diagnoses from 2010 to 2014, more than any other racial/ethnic subgroup of MSM in the United States. If current HIV diagnoses rates persist, about one in four Latino MSM in the United States will be diagnosed with HIV during their lifetime. Although some efficacious HIV prevention interventions for Latino MSM exist, none have focused on couples.

Long-term health outcomes of childhood sexual abuse and peer sexual contact among an urban sample of behaviourally bisexual Latino men.

While previous research indicates high rates of childhood sexual abuse among Latino men who have sex with men, few studies have examined the long-term health outcomes of childhood sexual abuse specifically among behaviourally bisexual Latino men. In a sample of 148 behaviourally bisexual Latino men in New York City, we examined associations between childhood sexual abuse and multiple dimensions of adult health: sexual risk behaviours; sexually transmitted infections incidence; polydrug use; depressive symptoms; and perceived stress. We compared outcomes between those with histories of childhood sexual abuse, those reporting peer sexual contact prior to age 13 and those with no sexual contact prior to age 13.

Adults Experiencing Homelessness in the US-Mexico Border Region: A Photovoice Project.

Homelessness is a social, economic, and political crisis in the United States. In particular, the US-Mexico Border region has seen a surge of homelessness, specifically among veterans, women victims of intimate partner violence, and immigrants. In 2014, 12 persons in El Paso, TX, with experience of being homeless used the photovoice methodology to participate in a project titled, "The Voices and Images of the Residents of the Opportunity Center for the Homeless: A Visual Project on the Identity and Challenges Homeless Adults Face on the Border Region.

Syndemic Conditions Reinforcing Disparities in HIV and Other STIs in an Urban Sample of Behaviorally Bisexual Latino Men.

Syndemics research has made great contributions to understanding sexual risk among Latino men who have sex with men. However, such work often combines data for behaviorally bisexual men with data for men with exclusively same-sex partners. Using cross-sectional data from 148 behaviorally bisexual Latino men, this study explored the impact of syndemic factors-polydrug use, childhood sexual abuse, and depression-on sexual risk behaviors and STI incidence.
