AI Article Synopsis
- Researchers examined underexplored members of the Teloschistaceae family in South America, focusing on species from Bolivia and Peru using both molecular and morphological data.
- This study aimed to better represent South American taxa in recent phylogenetic classifications, particularly looking at lobate and squamulose forms.
- The researchers proposed three new genera and revised the classification of certain taxa, also confirming that the subfamily Brownlielloideae is a misclassification stemming from mixed data.
Article Abstract
Members of the poorly investigated family Teloschistaceae in South America, mostly from Bolivia and Peru, were examined using molecular and morphological data here for the first time. In recent phylogenetic reclassifications of Teloschistaceae, South American representatives were poorly represented but shown to belong to subfamilies Teloschistoideae and Xanthorioideae. In this study, we expanded the sampling of South American taxa and investigated mainly the lobate, sublobate, and squamulose members of s.l., using morphological characters and a molecular phylogeny based on a combined three-locus data set (one mitochondrial and two nuclear loci). Building upon new phylogenies at the family and subfamily levels (Teloschistoideae), we propose here three new genera: , and , with the type species , and . We also propose to reduce to synonymy with and to synonymy with and introduce three new combinations: , and is reported as new to Bolivia. A critical revision of the subfamily Brownlielloideae confirmed recent findings that it is an artifactual taxon based on a "chimeric" data set, with the type genus being part of Teloschistoideae.

Submerged or partially floating seagrasses in marine or brackish waters form productive seagrass beds, feeding grounds for a rich and varied associated biota, play key ecological roles in mitigating climate change and provide ecosystem services for humanity. The objective of this study was to perform a temporal quali- and quantitative analysis on the scientific production on seagrasses in the Atlantic Ocean during last 64 years (1960 to 2024) through defined workflow by scientometric analysis on Scopus database. Publications in this database date back to 1969, comprising a total of 3.

Introduction: The maternal mortality crisis in the United States disproportionately affects women who are Black, especially those living in the Gulf South. These disparities result from a confluence of healthcare, policy, and social factors that systematically place Black women at greater risk of maternal morbidities and mortality. This study protocol describes the Southern Center for Maternal Health Equity (SCMHE), a research center funded by the National Institutes of Health in 2023 to reduce preventable causes of maternal morbidity and mortality while improving health equity.

Objective: The aim of this scoping review is to map the concept of resilience and its measurement along with co-occurring theoretical constructs within nursing research using the COVID-19 pandemic as a critical date range for the current evidence.
Introduction: Resilience has a wide variety of definitions in research literature and is often measured through its co-occurring theoretical constructs. Nurse resilience is a key element in interventions targeting nurse well-being and has been tied to burnout and mental health.

The genus Linton, 1910 comprises species which parasitize herbivorous kyphosid fish. In the present study, a new species is described based on fresh specimens collected from from Rio de Janeiro. The new species is characterized by having the oral sucker infundibuliform with 10 lobes, prepharynx two times longer than pharynx, presence of oesophagus, testes slightly lobed, round ovary and rectum with muscular sphincter connected to the anus.

Introduction: The healthcare sector has great potential for promoting physical activity (PA) for chronic disease prevention, treatment and management; however, multiple adoption and implementation barriers exist, ranging from practice integration to information flow. In 2016, Exercise is Medicine Greenville (EIMG), a comprehensive clinic-to-community approach that involves PA assessment, recommendation and/or prescription and provider-based referral of patients to community-based PA programmes, was launched by Prisma Health in Greenville, South Carolina, USA. Since inception, variability has emerged in adoption and implementation, impacting patient reach, referral rates and engagement in the community-based PA programmes, highlighting the need for closer evaluation and refinement of strategies to maximise programme impact.
