Does settlement plate material matter? The influence of substrate type on fouling community development

Benthic community composition and ascidian abundance can differ dramatically between adjacent man-made and natural substrates. Although multiple factors, including light exposure, surface orientation, predation exposure, and habitat type, are known to contribute to these patterns, few studies have directly tested the influence of substrate identity on community development. We compared fouling communities on settlement plates composed of commonly occurring natural (granite) and artificial (concrete, high density polyethylene, and PVC) marine materials deployed from late May to mid November 2014 from a floating dock in Newcastle, NH. We sought to determine if observed patterns resulted from differential recruitment onto substrate materials or post-settlement survival and growth. To do this, half of the plates were cleaned during bi-weekly examinations, and half were left un-cleaned. Preliminary analyses indicate that community composition differs between substrate types. These results will help us understand how substrate features contribute to non-native species establishment and habitat dominance, and may inform decisions regarding material usage in marine construction. These findings also underline the importance of settlement substrate choice in scientific studies, as plate material may influence experimental conclusions

Diversity in Mental Health Among Generations in the LGBTQI Community

This study captured the various mental health impacts among youth, younger adults, and older adults in the LGBTQI community. The LGBTQI community embodies a diverse set of subgroups that includes youth, younger adults, and older adults. Many in the LGBTQI community face prejudice, discrimination, harassment, and even rejection from family members. Youth and younger adults in LGBTQI communities are often victims of school violence, as well as intimate partner violence, and typically show signs of psychosocial adjustment disorder and psychological distress. LGBTQI older adults, although have a high incidence of social isolation and depression, are shown to be more resilient over psychological stressors compared to LGBTQI youth and younger adults.

More than a Nuisance: Implications of Food Marketing for Public Health Efforts to Curb Childhood Obesity

Fifteen years ago, public health experts urged industry, governments, and advocates to take action to dramatically improve the unhealthy food-marketing environment surrounding children in order to address the global childhood obesity crisis. Since then, research has confirmed that food marketing to children has far-reaching negative effects on their diets and health, takes advantage of adolescent vulnerabilities, and contributes to health disparities. In addition, digital marketing has profoundly changed young people's engagement with brands. Moreover, reliance on industry self-regulation as a solution has proven ineffective. Government-led policies have been more successful, but they remain limited in scope and challenging to adopt and implement. New approaches are necessary to increase public and policy maker awareness that food marketing is more than a nuisance, that it threatens the long-term health of children and adolescents worldwide, and that meaningful governmental action is urgently required to curtail industry's negative impact on young people's well-being

Patient perceptions in receiving LGBTQIA culturally competent health care

Background: There is a large amount of documented evidence demonstrating that health care providers are caring for diverse populations. This warrants a level of cultural competence (CC) when making health care decisions. Traditionally, Race and ethnicity have been the focus in CC. However, criteria such as sexual orientation and gender identity are often forgotten, or left out altogether. Because of this, patients whose sexual orientation or gender is a minority, may often receive inadequate treatment. This is in part due to the health care providers lack knowledge in this type of CC or present sexual prejudices. Because of this, research is needed to investigate the perceptions of patients that identify as lesbian, gay, bisexual, transgender, queer/questioning, intersex, ally (LGBTQIA) when receiving health care.Methods: Cross-sectional design consisting of 140 participants (male=78, female=50, transgender=5, other=7; heterosexual=16, gay/lesbian=72, bisexual=43, other=9, mean age=26.97 ± 7.67). Participants were recruited using a snowball sampling method via email and list-serves. A modified version of the Gay Affirmative Practice (GAP) (reliability a = 0.962), was delivered online to participants to determine need of LGBTQIA cultural competent treatment by health care providers. Means and standard deviations were calculated for each variable (gender, sexual orientation), as well as an overall GAP score (out of 150). Two, single one-way ANOVAs (gender and sexual orientation) were performed with GAP score as the dependent variable.Results: Calculated GAP scores: All=128.82 ± 18.48, male=128.49 ± 15.60, female=130.35 ± 17.10, transgender=129.80 ± 9.31, other=143. 57, heterosexual=129.33 ± 17.12, gay or lesbian=128.25 ± 15.85, bisexual/omni/pansexual/queer/non-monosexual=132.79 ± 14.99, other=131.38 ± 20.37. ANOVA results were modified with Kruskal-Wallis adjustments due to violation of normality and homogeneity of variance, and now are represented by Chi Squares. Gender was the single significant outcome, (X2(3) =8.01, p <0.05). Post hoc testing of gender demonstrated statistical significant in comparing males vs. other.Conclusions: Patients do find it necessary for health care providers to have specific training and/or knowledge in LGBTQIA CC. A majority of results demonstrate strongly agree that health care providers need better CC in LGBTQIA. In comparison of GAP scores in gender, the category of other demonstrates a great need for CC in LGBTQIA in health care providers. Males demonstrated a much lower score, indicating a low priority for LGBTQIA CC in health care. With an increasing LGBTQIA patient population, patients feel the ever increasing need for health care providers to provide knowledgeable, competent, and fair treatment/care

Bioelectric-calcineurin signaling module regulates allometric growth and size of the zebrafish fin

AbstractThe establishment of relative size of organs and structures is paramount for attaining final form and function of an organism. Importantly, variation in the proportions of structures frequently underlies adaptive change in morphology in evolution and maybe a common mechanism underlying selection. However, the mechanism by which growth is integrated within tissues during development to achieve proper proportionality is poorly understood. We have shown that signaling by potassium channels mediates coordinated size regulation in zebrafish fins. Recently, calcineurin inhibitors were shown to elicit changes in zebrafish fin allometry as well. Here, we identify the potassium channelkcnk5bas a key player in integrating calcineurin’s growth effects, in part through regulation of the cytoplasmic C-terminus of the channel. We propose that the interaction between Kcnk5b and calcineurin acts as a signaling node to regulate allometric growth. Importantly, we find that this regulation is epistatic to inherent mechanisms instructing overall size as inhibition of calcineurin is able to bypass genetic instruction of size as seen insofand wild-type fins, however, it is not sufficient to re-specify positional memory of size of the fin. These findings integrate classic signaling mediators such as calcineurin with ion channel function in the regulation of size and proportion during growth.</jats:p

A cross-genus comparison of grazing pressure by two native marine herbivores on native, non-native naturalized, and non-native invasive Sargassum macroalgae

In marine systems, algal abundance and community composition is often heavily influenced by top-down control by herbivores. As a result, examining the extent to which native herbivores exert grazing pressure on non-native marine algae can provide valuable insight into mechanisms controlling invasion success. The purpose of this study was to examine the grazing preferences of two common intertidal and subtidal herbivores on three congeneric species of marine algae with unique colonization histories in San Diego, California, USA, to determine if grazing pressure, or lack thereof, may help explain invasion success. We provide evidence that neither native Sargassum agardhianum, nor non-native Sargassum horneri, are particularly palatable to purple urchins or black turban snails, but that non-native Sargassum muticum is consumed by both native herbivores. We also provide evidence that when given a choice of all three species neither herbivore exhibits a significant grazing preference for any algal species. We suggest that other mechanisms may determine the invasion success of the two non-native algal species and the overall distribution and abundance patterns of these species, and we discuss potential directions for future work
