Family functioning mediation in tic severity and quality of life for children with Tourette syndrome

BACKGROUND Tourette syndrome (TS) is recognized as a neurodevelopmental disorder profoundly influenced by familial factors, particularly family functioning. However, the relationship among family functioning, tic severity, and quality of life in individuals with TS during childhood and adolescence remains unclear. We hypothesized that family functioning plays a role in the association between the severity of TS and quality of life in children. AIM To determine the role of family functioning in the relationship between TS severity and quality of life. METHODS This study enrolled 139 children (male/female = 113/26) with TS. We assessed tic severity using the Yale Global Tic Severity Scale, quality of life via the Tourette Syndrome Quality of Life Scale, and family functioning through the Family Assessment Device. Our analysis focused on correlating these measures and exploring the mediating role of family functioning in the relationship between tic severity and quality of life. Additionally, we examined if this mediating effect varied by gender or the presence of comorbidity. RESULTS We found that family communication dysfunction had a significant mediating effect between tic severity and both psychological symptoms (indirect effect: Β = 0.0038, 95% confidence interval: 0.0006-0.0082) as well as physical and activities of daily living impairment (indirect effect: Β = 0.0029, 95% confidence interval: 0.0004-0.0065). For vocal tic severity, this mediation was found to be even more pronounced. Additionally, in male participants and those without attention deficit hyperactivity disorder, the mediating effect of family communication dysfunction was still evident. CONCLUSION Our study highlights the impact of family functioning on the tic severity and the quality of life in children. This relationship is influenced by gender and comorbid conditions like attention deficit hyperactivity disorder.

Exploring interprofessional collaboration in the intensive care unit

Background: Critical care units require an interprofessional management approach to optimise patients’ health. Clinical education and training delivered in remote healthcare settings are vital for fostering interprofessional collaboration (IPC) among health science students for future team functioning.Objectives: Our study explored the IPC among clinicians in the intensive care unit (ICU) setting at two South African decentralised clinical training facilities to understand the existing collaborative practices that students are exposed to during their clinical training.Method: A qualitative study design, utilising semi-structured interviews, was used to gather information on the experiences of 40 purposively selected participants working in the ICU settings at the two clinical sites. Data collected from the interviews were transcribed verbatim and thematically analysed.Results: Four major themes were identified from the data, namely, scope-of-practice dispute, teamwork disruption, organisational obstacles and future aspirations.Conclusion: Participants believed that a lack of professional regard by medical doctors and an inadequate understanding of the role of other professionals impeded appropriate referral practice and collaborative team functioning. Under-exposure to interprofessional education (IPE) at an undergraduate level and the pervasive medical hierarchy were perceived as a primary attributable cause of this phenomenon. Moreover, the coronavirus disease 2019 (COVID-19) pandemic and persistent staff shortages purportedly obstructed potential opportunities to collaborate in multidisciplinary meetings. Participants believed that improving undergraduate IPE and compulsory multidisciplinary meetings to promote communication would improve team functioning in these clinical settings.Clinical Implications: Undergraduate IPE is a feasible approach to improve collaborative care in ICUs to achieve better patient outcomes.

SPLASH: Split-Body Randomized Clinical Trial of Poly-l-Lactic Acid for Adipogenesis and Volumization of the Hip Dell.

Injectable poly-l-lactic acid (PLLA-SCA) increases extracellular matrix to improve skin quality. The hip dell is an underappreciated element of gluteal aesthetics. Adipose tissue has roles in aesthetics and skin functioning. To investigate the efficacy of PLLA-SCA treatment to induce adipogenesis and volumize the hip dell. This was a double-blinded, split-body trial of 15 women with hip dell volume deficits. Each subject was randomized to have 1 hip dell treated with 150 mg of PLLA-SCA while the contralateral hip dell received the equivalent volume of saline. Subjects received 3 treatments at 1-month intervals and were followed for 9 months. Assessments included physician global aesthetic improvement scale, ultrasonography, and histologic examination. Blinded investigators rated PLLA-SCA-treated hip dells as improved and much improved. The dermis and adipose layers increased in thickness by 26.1% and 27%. These measures, in addition to collagen and elastic fiber quality, were significantly improved compared with saline-treated hip dells, which did not change from baseline. Subject satisfaction was also significantly greater on the PLLA-SCA-treated side. No subject experienced significant adverse effects. Poly-l-lactic acid is a safe and effective method for durable volumization and aesthetic improvement of the hip dell. PLLA-SCA may promote adipogenesis and elastogenesis.

Maternal alexithymia and caregiving behavior: the role of executive functioning -A FinnBrain Birth Cohort study.

The growing interest in parental cognition calls for research clarifying how cognition interacts with other parenting determinants to shape caregiving behavior. We studied the interplay between executive functioning (EF; cognitive processes that enable goal-directed thinking and behavior) and alexithymic traits (characterized by emotion processing/regulation difficulties) in relation to emotional availability (EA; the dyad's ability to share an emotionally healthy relationship). As EF has been reported to shape parents' ability to regulate thoughts and emotions during caregiving, we examined whether EF moderated the association between maternal alexithymic traits, and EA. Among 119 mothers with 2.5-year-olds drawn from the FinnBrain Birth Cohort, EF was measured with Cogstate tasks, alexithymic traits with the Toronto Alexithymia Scale (TAS-20), and caregiving with the Emotional Availability Scales (EAS). More alexithymic traits on the TAS-20 subscale Externally Oriented Thinking (EOT) were associated with poorer caregiving in a hierarchical regression analysis (ΔR2 = 0.05, p = .01). A marginally significant moderation effect was found when adding the EOTxEF interaction term to the model (ΔR2 = 0.03, p = .06). These associations weakened slightly when controlling for education level. Estimation of simple slopes and a Johnson-Neyman figure indicated a significant association between higher EOT and lower EAS, that increased in strength as EF decreased from the group mean level. The influence of cognitive alexithymic traits on EA could be especially pronounced among low EF parents, but further studies are needed to support and extend the findings. The potential role of parental reflective functioning in this context is discussed.

Enhancing Knowledge Sharing on Social Media: The Role of Functionalities in User Engagement and Information Quality

This study investigates functionalities on social media platforms that promote effective knowledge sharing, focusing on information quality and user engagement. A systematic literature review (SLR) was conducted to analyze relevant research. The findings reveal that functionalities like content creation and curation tools, user interaction and feedback mechanisms, community building and gamification elements, and knowledge filtering and recommendation systems all contribute to a positive knowledge-sharing environment. These functionalities empower users to create high-quality content, engage in discussions that refine information, and discover trustworthy sources. The study highlights the potential of social media platforms for knowledge sharing but acknowledges that the effectiveness of functionalities can vary depending on the platform and audience. Future research is recommended to explore the most impactful functionalities in specific contexts and the interplay between functionalities, user behavior, and information quality.

Curved multiplanar reformatting allows the accurate histological delineation of hippocampal subfields.

Hippocampal subfields perform specific roles in normal cognitive functioning and have distinct vulnerabilities in neurological disorders. However, measurement of subfields with MRI is technically difficult in the head and tail of the hippocampus. Recent studies have utilized curved multiplanar reconstruction (CMPR) to improve subfield visualization in the head and tail, but this method has not yet been applied to histological data. We utilized BigBrain data, an open-source database of serially sectioned histological data for our analyses. The left hippocampus was segmented according to histological criteria by two raters in order to evaluate intra- and inter-rater reliability of histology-based segmentation throughout the long axis. Segmentation according to our previous protocol for the hippocampal body was then compared to these histological measurements to evaluate for histological validity. Agreement between segmentations was evaluated using Dice similarity coefficients (DSCs). Intra-rater reliability (DSCs) of histological segmentation was excellent for all subfields: CA1 (0.8599), CA2 (0.7586), CA3/CA4/DG (0.8907), SLM (0.9123), subiculum (0.8149). Similarly, inter-rater reliability analysis demonstrated excellent agreement (DSCs) for all subfield locations: CA1 (0.8203), CA2 (0.7253), CA3/CA4/DG (0.8439), SLM (0.8700), subiculum (0.7794). Finally, histological accuracy (DSCs) for our previous protocol was excellent for all subfields: CA1 (0.8821), CA2 (0.8810), CA3/CA4/DG (0.9802), SLM (0.9879), subiculum (0.8774). When subfields in the hippocampus head, body, and tail were analyzed independently, DSCs also showed excellent agreement. CMPR allows reliable subfield segmentation based on histological criteria throughout the hippocampal head, body, and tail. Our previous protocol for the hippocampal body can be applied to provide histologically valid subfield measurements throughout the entire hippocampal long axis.

Exosomal Non-coding RNAs: A New Approach to Melanoma Diagnosis and Therapeutic Strategy.

Malignant melanoma (MM) is a highly aggressive cancer with a poor prognosis. Currently, although a variety of therapies are available for treating melanoma, MM is still a serious threat to the patient's life due to numerous factors, such as the recurrence of tumors, the emergence of drug resistance, and the lack of effective therapeutic agents. Exosomes are biologically active lipid-bilayer extracellular vesicles secreted by diverse cell types that mediate intercellular signal communication. Studies found that exosomes are involved in cancer by carrying multiple bioactive molecules, including non-- coding RNAs (ncRNAs). The ncRNAs have been reported to play an important role in regulating proliferation, angiogenesis, immune regulation, invasion, metastasis, and treatment resistance of tumors. However, the functional role of exosomal ncRNAs in MM remains unknown. Therefore, this review summarizes the current state of melanoma diagnosis, treatment, and the application of exosomal ncRNAs in MM patients, which may provide new insights into the mechanisms involved in melanoma progression and serve as biomarkers for diagnosis and therapeutic targets.

Exploring the Role of Social Support and Sexual Functioning: A Study of Chemsex and Sober Sex in Men Who Have Sex with Men

ABSTRACT Research on chemsex, the intentional use of certain drugs in sexual contexts by gay men and other men who have sex with men (MSM), has been growing in recent years although, even today, much of it focuses on drug use and its consequences, rather than on the sexual and social experiences of users. This study aimed to explore the influence of social support and sexual functioning on the frequency of chemsex and sober sex. A sample of 160 MSM WAS recruited through social media and NGOs. Through regression analysis, it was found that lower perceived social support and greater number of routes of drug administration predicted a higher frequency of chemsex practice. On the other hand, higher perceived social support, higher levels of desire and arousal, and fewer routes of drug administration predicted a higher frequency of engaging in sober sex. This study provides empirical evidence that both social support and sexual functioning are key elements in chemsex and have an impact on both the frequency of chemsex and sober sex. Given the importance of these elements, we suggest that interventions should be framed holistically. Nevertheless, not all chemsex is problematic and it is a free choice in sexuality.

Genomic signatures of inbreeding and mutation load in tree ferns.

Ferns (Pteridophyta), as the second largest group of vascular plants, play important roles in ecosystem functioning. Homosporous ferns exhibit a remarkable range of mating systems, from extreme inbreeding to obligate outcrossing, which may have significant evolutionary and ecological implications. Despite their significance, the impact of genome-wide inbreeding on genetic diversity and mutation load within the fern lineage remain largely unexplored. In this study, we utilized whole-genome sequencing to investigate the genomic signatures of inbreeding and genetic load in three Alsophila tree fern species. Our analysis revealed extremely high inbreeding in A. spinulosa, in contrast to the predominantly outcrossing observed in A. costularis and A. latebrosa. This difference likely reflects divergent mating systems and demographic histories. Consistent with its extreme inbreeding propensity, A. spinulosa exhibits reduced genetic diversity and a pronounced decline in effective population size. Comparison of genetic load revealed an overall reduction in deleterious mutations in the highly inbred A. spinulosa, highlighting that long-term inbreeding may have contributed to the purging of strongly deleterious mutations, thereby prolonging the survival of A. spinulosa. Despite this, however, A. spinulosa carries a substantive realized genetic load that may potentially instigate future fitness decline. Our findings illuminate the complex evolutionary interplay between inbreeding and mutation load in homosporous ferns, yielding insights with important implications for the conservation and management of these species.

Parental conflict and adolescents' socially adverse emotions: the mediating role of family functioning.

To examine the process of how parental conflict and family functioning influence adolescents' socially adverse emotions (shyness and loneliness). Stratified cluster sampling was used to conduct a questionnaire survey among 1,100 junior high school students from three junior high schools in Beijing, Chongqing, and Shijiazhuang, China. (1) The overall experience of adolescents' socially adverse emotions was at the moderate level; boys' experience of shyness and loneliness was significantly higher than that of girls; the experience of shyness and loneliness in the second grade was significantly higher than that in the first grade; (2) Parental conflict was significantly negatively correlated with family functioning and significantly positively correlated with adolescents' socially adverse emotions, while family functioning was significantly negatively correlated with adolescents' socially adverse emotions; (3) Family functioning partially mediates the relationship between parental conflict and adolescents' shyness and completely mediates the relationship between parental conflict and adolescents' loneliness. Compared to adolescents' shyness, family functioning plays a more important mediating role in the relationship between parental conflict and adolescents' loneliness.

Modelling the associations between parental depressive symptoms, hypomanic traits, and infant socio-emotional development: The mediating role of parental reflective functioning

BackgroundAlthough understanding of maternal hypomania in the postpartum period is gradually improving, the intergenerational pathways of risk associated with hypomania in the context of postpartum depression remain unknown. It is also unclear whether distinct or shared pathways of risk exist for infants exposed to different parental mood characteristics and whether these pathways are mediated by parental reflective functioning. MethodsAn online survey was administered to 1788 parents (89 % mothers, 50 % White) who were primary caregivers of a child under 2. Structural equation modelling techniques were employed to model direct and indirect associations between parental depressive symptoms, hypomanic traits and infant socio-emotional development, investigating the mediating role of parental reflective functioning. ResultsElevated levels of parental depressive symptoms, in the presence of hypomanic personality traits, were directly associated with infant socio-emotional challenges, without affecting parental reflective functioning. However, higher levels of parental hypomanic traits in the postnatal period displayed a fully mediated pathway of risk transmission to infants' socio-emotional development via their negative association with parental reflective functioning. LimitationsResults should be interpreted with caution as the reliance on self-and-parent-reported scales may have introduced biases influenced by individual perceptions and situational factors. Additionally, the cross-sectional design of this study inhibits establishing cause-and-effect relationships. ConclusionsOverall, these results highlight the critical role of both parental depressive symptoms and hypomanic traits on infant socio-emotional development, suggesting that supporting parental mood regulation and mentalizing abilities in the postnatal period could reduce the risk of early maladaptive socio-emotional trajectories in children.

The role of carbon textile surface functionalities in reactive adsorption of vapor and liquid 2-chloroethyl ethyl sulfide: Evaluating interactions at the interface

A carbon textile (CT) was chemically modified to increase its surface activity and promote the adsorption and degradation of 2-chloroethyl ethyl sulfide (CEES) - a surrogate for mustard gas. CT was initially subjected to oxidation (CTO), and then heated under ammonia (CTON) or hydrogen sulfide (CTOS) atmosphere to incorporate nitrogen or sulfur functionalities, respectively. Detoxification experiments were performed in closed vials using either vapor or liquid forms of CEES. The maximum vapor weight uptakes on CT, CTO, CTOS, and CTON were 399, 372, 434, and 489 mg/g, respectively. All textiles were able to prevent the vaporization of CEES liquid droplets. Although similar reaction products were detected in both vapor and liquid systems, the marked differences in the extent of CEES chemical transformation on the surfaces of the textiles indicate distinct detoxification pathways influenced by surface chemistry. Even though the heterogeneous surface of CTO, enriched with oxygen surface groups, facilitated various reactions, hydrolysis was the predominant pathway. The thermal treatment, regardless of the atmosphere, reduced the oxygen content, decreasing the extent of hydrolysis. However, incorporating basic surface groups such as pyridines, amines, or weak acids such as thiols promoted dehydrohalogenation as the main detoxification pathway on these samples.

Impact of Epigenetics, Diet, and Nutrition-Related Pathologies on Wound Healing.

Chronic wounds pose a significant challenge to healthcare. Stemming from impaired wound healing, the consequences can be severe, ranging from amputation to mortality. This comprehensive review explores the multifaceted impact of chronic wounds in medicine and the roles that diet and nutritional pathologies play in the wound-healing process. It has been well established that an adequate diet is crucial to proper wound healing. Nutrients such as vitamin D, zinc, and amino acids play significant roles in cellular regeneration, immune functioning, and collagen synthesis and processing. Additionally, this review discusses how patients with chronic conditions like diabetes, obesity, and nutritional deficiencies result in the formation of chronic wounds. By integrating current research findings, this review highlights the significant impact of the genetic make-up of an individual on the risk of developing chronic wounds and the necessity for adequate personalized dietary interventions. Addressing the nutritional needs of individuals, especially those with chronic conditions, is essential for improving wound outcomes and overall patient care. With new developments in the field of genomics, there are unprecedented opportunities to develop targeted interventions that can precisely address the unique metabolic needs of individuals suffering from chronic wounds, thereby enhancing treatment effectiveness and patient outcomes.

Soil response in a Mediterranean forest ecosystem of Southeast Spain following early prescribed burning

The escalation of global warming, high temperatures, and wildfire frequency in dry ecosystems, including semi-arid landscapes, has resulted in increased wildfire regimes, compromising ecosystem resistance and resilience. To mitigate these risks, prescribed burning (PB) is being employed as a preventive measure to modify fuel loads in forest ecosystems. However, fire can also impact soil structure and microbiota, which play critical roles in nutrient cycling, biodiversity conservation, and overall ecosystem functioning. Therefore, understanding post-fire processes is essential for sustainable forest management. However, while previous studies have explored the effects of prescribed fire management on semi-arid soil properties in Mediterranean forest ecosystems, gaps remain in our understanding of its specific impact on the physical structure, chemical composition, and biological activities of soils.In this study, we conducted early spring PB in SE Spain in 2021 and assessed the ecological and temporal effects of PB on semi-arid soils. Soil respiration (SR) measurements using automatic CO2 flow chambers were employed to evaluate microbiota recovery. To examine impacts on soil structure we evaluated physicochemical characteristics, soil hydraulic conductivity (SHC), and soil water repellency (SWR). No significant differences were observed in any of the variables studied after one year. However, immediate effects were detected shortly after the PB. Our research specifically targeted soil structure and microbiota in a semi-arid landscape with poor soils, characterized by slower recovery and potentially fragile ecosystems. These results provide valuable insights for forest management practices, indicating that prescribed fire management strategies in similar ecosystems are unlikely to cause adverse effects on soil health. However, further research is warranted to explore the potential effects of prescribed fire intensity and seasonality. Future studies can focus on investigating these factors to provide more targeted recommendations for effective forest management strategies and wildfire prevention efforts.

Mediating Role of Social Support and Family Functioning on Quality of Life of Family Caregivers of Individuals With Alcohol Use Disorder

Background: Caring for persons with alcohol use disorder (AUD) significantly affects the quality of life (QoL) of caregivers. According to Lazarus and Folkman’s Stress and Coping Model (1984), the severity of alcohol consumption (SAC) is a major stressor for AUD caregivers. These stressors impact well-being, with QoL linked to caregivers’ coping resources, especially social support (SS) and family functioning (FF). The study aimed to investigate the mediating roles of SS and FF in the relationship between the SAC and caregivers’ QoL. Material and Methods: A cross-sectional study was conducted in two psychiatric hospitals in Amritsar city, Punjab. We used a purposive sampling technique to collect data from 128 family caregivers aged 18 and above who were caring for male patients with AUD aged between 20 and 65. The assessment tools used were the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF), Alcohol Use Disorders Identification Test (AUDIT), Family Assessment Device (FAD), and PGI Social Support Questionnaire (PGI SSQ). Results: There is a significant and partial mediation of the association between SAC and QoL by both SS and FF ( P < .001, 99% CI). Moreover, SAC (r = –0.519), FF (r = –0.603), and SS (r = 0.641) showed significant correlations with caregivers’ QoL ( P < .001). The mean scores for SAC, SS, FF, and QoL were 22.66 (11.38), 50.88 (9.45), 127.18 (43.85), and 84.13 (18.70), respectively, suggesting moderate SAC in patients, moderate to high perceived SS levels, moderate perception of family dysfunction, and moderate to high QoL among the caregivers. Conclusion: SAC detrimentally impacts caregivers’ QoL both directly and indirectly through SS and FF, with the latter serving as mediators, partially mitigating SAC’s negative impact. Clinical implications underscore the importance of tailored interventions, emphasizing the strengthening of support systems and consideration of diverse FF domains for personalized approaches. The findings contribute valuable insights for developing targeted interventions customized to the specific needs of AUD caregivers to enhance their overall QoL.

Vegetable Mountain Products, as Functional Food. A Cross-sectional Study of European Romanian Agricultural Producers

Background:: Mountain areas, in a normal ecosystemic context as the analyzed region from the European Romanian Carpathians, offer healthier solutions through different agronomical practices and solutions designed for the production of functional food. The paper approaches a chain formed by mountain functional food – agronomic practices – mountain products commerce, the purpose being the development of the entire mountain products value chain from an area focusing on the matrix "from the farm to the fork". The paper analyzes highly consumed mountain products with functional food roles Allium cepa, Allium sativum, Cucumis sativus, Capsicum, and Solanum lycopersicum. Objective: The research highlights the importance of vegetable mountain products as a functional food in the current hunger and environment contexts, in a more and more polluted world Methods:: The experimental, clinical, and agronomical research, together with the production territorial profile, show that mountain products present high qualitative valences comparatively with low-land areas or with reference values given by USDA. Results:: According to macro-nutritional and micro-nutritional analysis – lipids-fats, saturated fatty acids, protein, cyanocobalamin (B12), ergocalciferol (D2 ), cholecalciferol (D3 ), iron and calcium – Allium sativum dominates the mountain product's top with a functional food role. Instead of this, mountain producers prefer to cultivate mountain products with a higher income horizon. Conclusion:: Functional food represents an imperative in a more polluted world. Being less polluted than other ecosystems, the mountain area offers healthier agricultural products and requires notable investments, together with more involved agronomy.

Gene expression analysis of microRNA-1285 in the South Indian oral squamous cell carcinoma population.

Oral squamous cell carcinoma (OSCC) is the most common oral malignant tumor, which has poor prognosis. The traditional investigative modality is invasive biopsy which is the gold standard for diagnosis. In recent years, alternative methods like non-invasive biomarkers have been studied for their potential role in early diagnosis and prognosis. Among them, microRNAs (miRNAs or miRs) are short non-coding RNAs that regulate gene expression in various diseases, including OSCC. Several miRNAs are being researched as non-invasive biomarkers as well as novel therapeutic targets in the treatment of OSCC. MiR expression can be upregulated or downregulated in OSCC. Among the reported miRNAs, miR-1285 is an important miRNA found to be involved in OSCC. The aim of the current study was to quantify the levels of miR-1285 in OSCC samples and to validate their potential role as biomarkers for OSCC detection. Sixteen samples of cancer tissue and normal tissue were evaluated from a total of 25 patients, in the study, conducted in the Department of Oral and Maxillofacial Surgery. The tissues were processed for H&E staining and gene expression analysis of miR-1285. The samples were collected after proper informed consent from the patients. Total RNA isolated was reverse transcribed into cDNA which was used in the gene expression analysis using qRT-PCR. The histopathological examination confirmed the OSCC cases and the gene expression analysis revealed that miR-1285 was significantly downregulated in OSCC tissues. Since miR-1285 showed significant difference between the OSCC and normal tissues it could be postulated as a potential biomarker and therapeutic target for OSCC. Further in-vitro and in-vivo studies could validate their functional role in OSCC.

Effects of Mesozooplankton Growth and Reproduction on Plankton and Organic Carbon Dynamics in a Marine Biogeochemical Model

AbstractMarine mesozooplankton play an important role for marine ecosystem functioning and global biogeochemical cycles. Their size structure, varying spatially and temporally, heavily impacts biogeochemical processes and ecosystem services. Mesozooplankton exhibit size changes throughout their life cycle, affecting metabolic rates and functional traits. Despite this variability, many models oversimplify mesozooplankton as a single, unchanging size class, potentially biasing carbon flux estimates. Here, we include mesozooplankton ontogenetic growth and reproduction into a 3‐dimensional global ocean biogeochemical model, PISCES‐MOG, and investigate the subsequent effects on simulated mesozooplankton phenology, plankton distribution, and organic carbon export. Utilizing an ensemble of statistical predictive models calibrated with a global set of observations, we generated monthly climatologies of mesozooplankton biomass to evaluate the simulations of PISCES‐MOG. Our analyses reveal that the model and observation‐based biomass distributions are consistent ( = 0.40, total epipelagic biomass: 137 TgC from observations vs. 232 TgC in the model), with similar seasonality (later bloom as latitude increases poleward). Including ontogenetic growth in the model induced cohort dynamics and variable seasonal dynamics across mesozooplankton size classes and altered the relative contribution of carbon cycling pathways. Younger and smaller mesozooplankton transitioned to microzooplankton in PISCES‐MOG, resulting in a change in particle size distribution, characterized by a decrease in large particulate organic carbon (POC) and an increase in small POC generation. Consequently, carbon export from the surface was reduced by 10%. This study underscores the importance of accounting for ontogenetic growth and reproduction in models, highlighting the interconnectedness between mesozooplankton size, phenology, and their effects on marine carbon cycling.
