- Migratory Connectivity and Non‐Breeding Habitat Segregation Across Biogeographical Scales in Closely Related Seabird TaxaPublication . Morera‐Pujol, Virginia; Catry, Paulo; Magalhães, Maria; Péron, Clara; Reyes‐González, José Manuel; Granadeiro, José Pedro; Militão, Teresa; Dias, Maria P.; Oro, Daniel; Igual, José Manuel; Dell'Omo, Giacomo; Müller, Martina; Paiva, Vitor H.; Metzger, Benjamin; Neves, Verónica; Navarro, Joan; Karris, Georgios; Xirouchakis, Stavros; Cecere, Jacopo G.; Zamora‐Marín, José Manuel; Forero, Manuela G.; Afán, Isabel; Ouni, Ridha; Romdhane, Mohamed Salah; Felipe, Fernanda De; Zajková, Zuzana; Cruz‐Flores, Marta; Grémillet, David; González‐Solís, Jacob; Ramos, RaülIn highly mobile species, Migratory Connectivity (MC) has relevant consequences in population dynamics, genetic mixing, conservation and management. Additionally, in colonially breeding species, the maintenance of the breeding geographical structure during the non‐breeding period, that is, a strong MC, can promote isolation and population divergence, which ultimately can affect the process of lineage sorting. In geographically structured populations, studying the MC and differences in environmental preferences among colonies, populations, or taxa can improve our understanding of the ecological divergence among them.We investigated the MC and non‐breeding ecological niche of three seabird taxa from the genus colonies, we assess the level (from taxa to colony) at which MC and non‐breeding spatial and environmental segregation emerge. At a taxon level, we found a clear difference in the non‐breeding distributions between Cory's. and Scopoli's shearwaters, and a clear ecological divergence between Cory's and Cape Verde shearwaters. At an intermediate aggregation level, we found that birds breeding in proximity had similar non‐breeding habitat preferences, while birds breeding in very distant colonies (and therefore classified in different populations) had different non‐breeding habitat preferences. Furthermore, within each taxon, we found more structure (i.e. stronger MC) and non‐breeding divergence at an intermediate aggregation level than at the colony scale, where MC was weak. Main Conclusions These results suggest that conspecifics from nearby colonies mix in common non‐breeding areas, but not with birds from more distant colonies or different taxa. These results support the need for management and conservation strategies that take into account this structure when dealing with migratory species with high connectivity.
- Examining the connection between perceived stress and post-traumatic stress in women who experienced a traumatic childbirthPublication . Brandão, Sónia; Silva, Rosa; Abreu, Wilson; Brandão, Tânia; Prata, Ana Paula; Riklikiene, Olga; Jarasiunaite-Fedosejeva, Gabija; Mesa, Ernesto González; İsbir, Gözde Gökçe; İnci, Figen; Kömürcü-Akik, Burcu; Uriko, Kristiina; Governo, Tatiana; Thomson, GillAim: This study aimed to: (1) explore post-traumatic stress disorder symptoms in relation to sociodemographic, obstetric, and childbirth trauma factors; (2) assess the association between perceived stress levels and post-traumatic stress disorder symptoms; and (3) analyze how the duration of perceived stress affects post-traumatic stress disorder. Design: A cross-sectional study. Methods: Data were collected via an online survey, including demographic and obstetric information, traumatic childbirth events, post-traumatic stress disorder symptoms, and perceived stress levels and duration in the postpartum period. The study was conducted with 202 women who self-identified as having experienced a traumatic childbirth. Results: Post-traumatic stress disorder scores did not differ significantly by most sociodemographic or obstetric factors, but cesarean delivery was linked to higher post-traumatic stress disorder scores compared to vaginal delivery with forceps or vacuum extraction, mediated by increased perceived stress. Perceived stress levels showed a significant positive association with all post-traumatic stress disorder dimensions. Stress duration significantly was related to total post-traumatic stress disorder scores, with longer stress being associated with greater severity of symptoms. Conclusion: Cesarean delivery and prolonged, elevated stress during childbirth are key risk factors for post-traumatic stress disorder symptoms, highlighting the need for targeted postpartum mental health interventions.
- Does time matter? The role of time perspective and ageism in mental health along the lifespanPublication . Miguel, Isabel; von Humboldt, Sofia; Leal, Isabel; Thijssen, SandraTime perspective is a consistent personal viewpoint which evolves with age and may influence mental health across the lifespan. This study aims to: (1) compare time perspective, perceived ageism and mental health indicators, in three age cohorts across the lifespan; (2) examine the influence of time perspective on mental health indicators (depression, anxiety, and stress); and (3) assess whether ageism serves as a moderating factor between time perspective and mental health indicators. 1311 participants from three distinct age groups (18–39, 40–59, and 60+) participated in this cross-sectional study. The following instruments were used: (a) Future Time Perspective Scale (FTPS); (b) Perceived Ageism Questionnaire (PAQ); (c) Depression, Anxiety, and Stress Scales (DASS-21); and (d) a sociodemographic, health and lifestyle questionnaire. MANOVAs and moderated regression analyses were performed on the data. Results indicated the highest levels of stress, anxiety and perceived ageism among younger and older participants. A decrease in FTP-Opportunity and an increase of FTP-Limitation, and the perception of increased positive ageism were found throughout the life cycle. FTP-Opportunity was found to negatively impact stress, anxiety, and depression, whereas FTP-Limitation showed a positive effect. Positive ageism also moderated the effects of FTP-Opportunity on anxiety and depression. This study unveils the intricate relationship between time perspective, mental health, and ageism, indicating that time perspective significantly influences mental health outcomes such as depression, anxiety, and stress. Addressing ageism emerges as a crucial component in enhancing mental health in individuals of all ages.
- Metastatic gastric adenocarcinoma in a grey seal Halichoerus grypus: Clinicopathological and immunohistochemical characterizationPublication . Marques, Gonçalo Nogueira; Marti-Garcia, Bernat; Leal, Miriam Oliveira; Silva, Nuno Urbani Ramos da; Flanagan, Carla Anne; Suárez-Bonnet, Alejandro; Leal, M OliveiraA 33 yr old female grey seal. Halichoerus grypus presented with inappetence and progressive weight loss. Medical management included blood analysis, imaging, and fecal evaluation, along with multimodal supportive therapy, which periodically improved the overall medical condition. Six months after the initial presentation, the clinical condition deteriorated significantly, including severe hyporexia, hematemesis, and marked neutrophilic leukocytosis, which led to the decision to euthanise based on welfare grounds. Necropsy findings included severe thickening of the distal esophagus, cardia, and proximal gastric fundus, as well as multiple nodular to cystic structures over the stomach’s serosa, omentum, and mesentery. Histologically, a mucinous gastric adenocarcinoma was diagnosed, with metastasis to the gastric lymph nodes and prominent carcinomatosis involving the omentum, mesentery, and diaphragm. Immunohistochemically, the gastric adenocarcinoma was positive for cytokeratin AE1/AE3, weakly positive for COX-2 and E-cadherin, and negative for vimentin. The Ki-67 proliferative index was low (0.8). Although rare, this case offers further insights into the clinical presentation, histopathology, and immunohistochemical profile of gastric tumors in pinnipeds.
- Optimistic and pessimistic cognitive judgement bias modulates the stress response and cancer progression in zebrafishPublication . Espigares, Felipe; Alvarado, M. Victoria; Abad-Tortosa, Diana; Varela, Susana A. M.; Sobral, Daniel; Faísca, Pedro; Paixão, Tiago; Oliveira, RuiCognitive judgement bias in decision-making under ambiguity occurs both in animals and humans, with some individuals interpreting ambiguous stimulus as positive (optimism) and others as negative (pessimism). We hypothesize that judgement bias is a personality trait and that individuals with a pessimistic bias would be more reactive to stressors and therefore more susceptible to stress-related diseases than optimistic ones. Here, we show that zebrafish judgment bias is a consistent behavioral trait over time, and that pessimistic and optimistic fish express phenotype-specific neurogenomic responses to stress. Furthermore, both phenotypes show differential activation of the hypothalamic-pituitary-interrenal axis in response to chronic stress, suggesting that optimists have a lower stress reactivity. Accordingly, optimists seem to be more resilient to disease than pessimists, as shown by a lower tumorigenesis in a zebrafish melanoma line [Tg(mtifa:HRAS-GFP)]. Together these results indicate that judgement bias is paralleled by differences in the stress response with implications for disease resilience.
