Macroclimatic niche similarity and species relatedness shift their influence on species co‐occurrence in bryophyte forest communities across scales
(10.1111/1365-2745.70043, 2025) Hurtado, Fernando; Gonçalves, João; Hespanhol, Helena; Ronquillo, Cristina; Estébanez, Belén; Aragón Carrera, Pedro; Medina, Nagore G.; Hortal, Joaquín
The processes driving species co-occurrence across scales are poorly understood. Bryophytes are especially interesting in this respect because, while they disperse over long distances and have broad distributions, they are particularly affected by local conditions due to their small size. We investigated the relationship between pairwise species associations within epiphytic bryophytes and their macroclimatic niche similarities and taxonomic relatedness at four scales (global, regional, habitat and microhabitat). We used community data for 2000 trees from 107 forests in the northwest Iberian Peninsula, and global occurrences for the 33 species with broad distributions, to calculate pairwise co-occurrence at each scale and bioclimatic niche similarity. We also obtained taxonomic distance matrices from the bibliography as a proxy for pairwise phylogenetic relatedness between species. Co-occurrence relates to macroclimatic niche similarity at all scales, but this relationship decreases towards smaller scales. Taxonomic affinity was also a good indicator of the pairwise co-occurrence not explained by macroclimatic niche similarity at the finest scales. Interestingly, at all scales, most pairwise relationships are positive or neutral rather than negative, although the direction of approximately 7% of these relationships shifts from positive at the microhabitat scale to negative at the regional scale. Macroclimatic requirements are progressively less important for species coexistence as scale diminishes, probably due to the effect of unmeasured local interactions, community-level processes, and microclimatic variations. Synthesis. Our results highlight that positive interactions may be at least as important as negative ones, if not more, for the coexistence of bryophyte species across scales. They also underscore that co-occurrence patterns may shift across scales, and the critical role of both macro- and microenvironmental conditions in shaping the life strategies and persistence of local populations of a plant group with population dynamics characterized by extensive geographic distributions. The implications of these findings go beyond their relevance for bryophyte ecology, challenging the prevailing assumption that limiting similarity processes primarily shape ecological communities.
Biased research reveals major gaps in fragmentation studies on the Spanish fauna
(European Journal of Forest Research, 2025) López Teixido, Alberto; Gonçalves, Stela R. A.; Moreno, María H. T.
Habitat loss and fragmentation globally threat biodiversity and ecosystem services. However, major research biases and knowledge gaps in biogeographical regions, taxonomic groups, landscape metrics and species’ biological responses studied, are recurrent in fragmentation studies. Detecting these biases and associated gaps is crucial to steer future research efforts and to guide applicable conservation policies. We conducted a systematic literature review and extracted data from 107 articles to evaluate biogeographic, taxonomic and ecological biases in fragmentation research on the highly-diverse terrestrial fauna in peninsular Spain. We observed that research was biased towards mountain ranges, southeastern drylands and nearly largest cities. Specifically, the Cantabrian Range comprised the highest density of studies, while open dehesas in western Spain and Atlantic coastal forests in the northwest were overlooked. We also found an overrepresentation of studies (77%) on vertebrates and a high positive relative bias for birds, while several invertebrate taxa were neglected in the literature. Fragmentation was more frequently considered than habitat loss. Habitat degradation and patch size reduction were the most studied metrics, while patch isolation, edge effect and matrix contrast were underrepresented. Assemblage-level species responses (abundance and richness) comprised 86% of studies, while interspecific interactions, genetics and individual conditions were largely underrepresented. Our findings indicate major gaps in the studies focused on the effects of habitat loss and fragmentation on the Spanish fauna. We recommend that fragmentation research in this diverse region from southern Europe needs to consider undersampled taxa, further fragmentation metrics and biological responses to avoid inappropriate inferences for conservation actions.
The Neanderthal cervical spine revisited
(Journal of Human Evolution, 2025) Palancar, Carlos A.; García Martínez, Daniel; Bastir, Markus
Recent studies have challenged the long-held notion that Neanderthals possessed a more stable and less lordotic cervical spine than modern humans. To investigate this hypothesis further, we conducted the first three-dimensional geometric morphometric analysis focused on the Neanderthal cervical spine, examining 43 classic Homo neanderthalensis cervical vertebrae alongside 243 Homo sapiens cervical vertebrae from diverse populations, including the whole cervical spine (C1–C7). The Neanderthal sample comprises specimens from well-known individuals such as La Ferrassie 1, La Chapelle-aux-Saints 1, Kebara 2, Shanidar 2, Regourdou 1, and the Krapina group, ensuring completeness for a detailed analysis. Our results reveal a distinct morphological difference—that is greater in the lower levels—in the Neanderthal cervical spine, including a craniocaudally shorter and mediolaterally wider shape, longer spinous processes, and horizontally oriented articular facets. Contrary to earlier hypotheses, the study challenges the notion of reduced cervical lordosis in Neanderthals, proposing instead a potentially greater lordotic curvature than in modern humans, as evidenced by articulated mean forms and Cobb angle measurements. These findings suggest robust neck musculature adaptations in Neanderthals, potentially reflecting biomechanical responses to support the head and inhibit joint displacement. The study also highlights implications for respiratory biomechanics, with differences in the orientation of transverse processes (attachment site of the scalene muscle) potentially influencing neck muscle length and function, which could affect respiratory capacity in Neanderthals. In summary, our comprehensive examination sheds new light on the morphology and functional implications of the Neanderthal cervical spine, offering valuable insights into the intricate adaptations of Neanderthals and their implications for functional morphology and evolutionary biology.
Impact of maternal antioxidant supplementation on ovarian development in prepuberal Iberian pig offspring.
(Translational Animal Science (TAS), 2025) Gómez, Gerardo; De las Heras Molina, Ana; Núñez, Yolanda; Sánchez Esquiliche, Fernando; Gómez Carballar, Fernando; Olivares Moreno, Álvaro; González Bulnes, Antonio; Rey Muñoz, Ana Isabel; Óvilo, Cristina; García Casco, Juan María; Muñoz, María; López Bote, Clemente José
A large percentage of breeding sows are culled before replacement costs are covered. Management and feeding are important factors affecting the performance of replacing gilts. Specifically, an optimal redox status has been linked to better fertility. Current research highlights the importance of neonatal criteria and age at puberty as factors in the gilt selection. Maternal antioxidant supplementation has benefits on the litter's performance, but there is scarce data on its effect on the future breeder. The aim of the study is to evaluate the effects of maternal supplementation with vitamin E (VE) and/or hydroxytyrosol (HXT) on prepuberal ovarian characteristics in Iberian pig offspring. Fifty Iberian sows were supplemented from day 85 of gestation until weaning with 30 or 100 mg/kg VE and 0 or 1.5 mg/kg HXT, resulting in four groups: VE30HXT0, VE100HXT0, VE30HXT1.5, VE100HXT1.5. At 110 d-old, 10 to 12 daughters were selected from each group to study weight, redox status and ovary histological measures and differences of selected gene expression patterns. Results showed that gilts with high VE had higher superoxide dismutase activity and malondialdehyde levels (P < 0.05 for both). Furthermore, total and oxidized glutathione showed a VE*HXT interaction, with VE100 gilts having the lowest activity values. These results imply a higher oxidative status with high VE supplementation. However, VE100 gilts also showed larger ovarian surfaces (P < 0.05 for planes 1, 6 and 10) and a lower proportion of small follicles (P < 0.05), which could mean a more proximal state to puberty of VE100 gilts. Furthermore, HXT effects on the ovarian surfaces and ovarian gene expression patterns were modulated by maternal parity. Thus, in gilts from primiparous mothers supplemented with HXT, plane 6 and plane 10 ovarian surfaces were smaller, and the expression of certain genes ( and ) were lower than those from primiparous sows without supplementation (P < 0.05 for all the interactions). In conclusion, dietary antioxidant supplementation during perinatal period affected ovary development during prepuberal stages of the progeny, with different effects according to maternal parity.
The synaptonemal complex central element SCEP3 interlinks synapsis initiation and crossover formation in Arabidopsis thaliana
(Nature Plants, 2025) Feng, Chao; Lorenz, Jana; Dreissig, Steven; Schubert, Veit; Wang, Baicui; Hartmann, Franziska; Cuacos, Maria; Fernández Jiménez, Nadia; Zhao, Ziliang; Eggeling, Christian; Câmara, Amanda Souza; Himmelbach, Axel; Heckmann, Stefan
The synaptonemal complex (SC) forms between homologous chromosomes during meiosis. In Arabidopsis thaliana, its central region (CR) is composed of the transverse filament protein ZYP1 and the central element proteins SCEP1 and SCEP2. Here we identify SCEP3 as a CR protein that is evolutionarily conserved across plant species. SCEP3 spatiotemporally overlaps with other CR proteins and localizes to the SC CR. The loss of SCEP3 prevents SC assembly, abolishes crossover (CO) assurance and interference, and eliminates sex-specific differences in CO rates (heterochiasmy) through increased CO in females. SCEP3 is required for a subset of COs in SC-deficient mutants, such as zyp1. Although SCEP3 physically interacts with ZYP1, it loads independently of other CR proteins. We propose that SCEP3 may associate with certain recombination intermediates, stabilizing them and/or recruiting additional factors, such as ZYP1, to a subset of these intermediates, thereby promoting and interlinking SC assembly and CO formation.
The pristine unused pulmonary surfactant isolated from human amniotic fluid forms highly condensed interfacial films
(Physiological Reports, 2025) Castillo Sánchez, José Carlos; Collada Marugán, Ainhoa; Batllori Badia, Emma; Galindo Izquierdo, Alberto; Cruz Rodríguez, Antonio; Pérez Gil, Jesús
Pulmonary surfactant is a lipid/protein complex that coats the alveolar air–liquid interface to minimize surface tension facilitating breathing mechanics. Native surfactant (NS) is typically obtained from lavages of animal lungs, where it has gone through structural alterations as a result of exposure to respiratory dynamics and highly oxidative environments. We have studied here the structure of interfacial films formed by human amniotic fluid surfactant (AFS), thought to maintain the structural and functional features of a fully operative still non-used surfactant, as it has not been subjected to breathing dynamics yet. The results show that AFS adsorbs better at the interface, to form films supporting higher compression rates, than NS upon spreading at comparable concentrations and amounts. Films formed by AFS exhibit condensed regions excluding fluorescently labeled lipids from the mere adsorption, while films formed by NS only showed segregation of ordered-like domains once subjected to compression–expansion dynamics. Finally, AFS films were consistent with the presence of solid-like highly ordered phases, while NS consisted under comparable conditions of a coexistence of liquid-disordered/liquid-ordered fluid phases. This indicates that operative surfactant films formed by freshly secreted surfactant could be much more condensed than previously supposed, likely providing maximal stability under breathing mechanics.
Home and family sense for children and adolescents in residential care: Evidence from Spain
(Child Indicators Research, 2025) García de León, Celia; Vallejo Slocker, Laura
Residential care in Spain supports 16,365 individuals, yet the role of feeling like a family in their lives remains unexplored. How this perception affects their quality of life is investigated in this research. Two studies were conducted: (1) a qualitative analysis of 318 children and adolescents (3–17 years) identified factors contributing to feeling like a family; these factors involved performing activities, events and traditions, positive emotions, social relationships and the physical environment; (2) a subsequent quantitative study of 254 participants (5–19 years) used structured interviews and the KidScreen instrument, employing chi-square tests and ordinal logistic regressions. Feeling like part of a family stems from shared activities, affectionate relationships, privacy, fair rules, social bonds, acceptance of their situation, satisfaction with their institution, and age. This feeling correlates with better quality of life, suggesting that interventions should enhance factors that foster familial bonds. The results identify specific aspects for assessing and improving the care of these children and young people. In the current global debate about deinstitutionalization, maintaining these elements is highly important to preserver the quality of care.
CARMENES input catalogue of M dwarfs IX. Multiplicity from close spectroscopic binaries to ultra-wide systems
(Astronomy & Astrophysics, 2025) Cifuentes, C.; Caballero, J. A.; González-Payo, J.; Amado, P. J.; Béjar, V. J. S.; Burgasser, A. J.; Cortés Contreras, Miriam; Lodieu, N.; Montes Gutiérrez, David; Quirrenbach, A.; Reiners, A.; Ribas, I.; Sanz-Forcada, J.; Seifert, W.; Zapatero Osorio, M. R.
Context. Multiplicity studies greatly benefit from focusing on M dwarfs because they are often paired in a variety of configurations with both stellar and substellar objects, including exoplanets. Aims. We aim to address the observed multiplicity of M dwarfs by conducting a systematic analysis using the latest available astropho-tometric data. Methods. For every star in a sample of 2214 M dwarfs from the CARMENES catalogue, we investigated the existence of resolved and unresolved physical companions in the literature and in all-sky surveys, especially in Gaia DR3 data products. We covered a very wide range of separations, from known spectroscopic binaries in tight arrangements (~0.01 au) to remarkably separated ultra-wide pairs (~10^(5) au). Results. We identified 835 M dwarfs in 720 multiple systems, predominantly binaries. Thus, we propose 327 new binary candidates based on Gaia data. If these candidates are finally confirmed, we expect the multiplicity fraction of M dwarfs to be 40.3_(−2.0)^(+2.1)%. When only considering the systems already identified, the multiplicity fraction is reduced to 27.8_(−1.8)^(+1.9)%. This result is in line with most of the values published in the literature. We also identified M-dwarf multiple systems with FGK, white dwarf, ultra-cool dwarf, and exoplanet companions, as well as those in young stellar kinematic groups. We studied their physical separations, orbital periods, binding energies, and mass ratios. Conclusions. We argue that based on reliable astrometric data and spectroscopic investigations from the literature (even when considering detection biases), the multiplicity fraction of M dwarfs could still be significantly underestimated. This calls for further high-resolution follow-up studies to validate these findings.

With biodiversity loss escalating globally, a step change is needed in our capacity to accurately monitor species populations across ecosystems. Robotic and autonomous systems (RAS) offer technological solutions that may substantially advance terrestrial biodiversity monitoring, but this potential is yet to be considered systematically. We used a modified Delphi technique to synthesize knowledge from 98 biodiversity experts and 31 RAS experts, who identified the major methodological barriers that currently hinder monitoring, and explored the opportunities and challenges that RAS offer in overcoming these barriers. Biodiversity experts identified four barrier categories: site access, species and individual identification, data handling and storage, and power and network availability. Robotics experts highlighted technologies that could overcome these barriers and identified the developments needed to facilitate RAS-based autonomous biodiversity monitoring. Some existing RAS could be optimized relatively easily to survey species but would require development to be suitable for monitoring of more ‘difficult’ taxa and robust enough to work under uncontrolled conditions within ecosystems. Other nascent technologies (for instance, new sensors and biodegradable robots) need accelerated research. Overall, it was felt that RAS could lead to major progress in monitoring of terrestrial biodiversity by supplementing rather than supplanting existing methods. Transdisciplinarity needs to be fostered between biodiversity and RAS experts so that future ideas and technologies can be codeveloped effectively.
The effect of a single functional neurology session on thermography of the genital region and sexual function in patients with premature ejaculation
(Sexual Medicine, 2025) Clemente-Suárez, Vicente Javier; Rey-Mota, Jorge; Escribano-Colmena, Guillermo; Marín, Noelia Vanessa; Fernández Lucas, Jesús
Background Premature ejaculation (PE) is a common male sexual dysfunction with limited long-term therapeutic options. Pharmacological and behavioral treatments often yield only temporary improvement, and alternative neuromodulatory strategies remain underexplored. Functional neurology, which targets autonomic and sensory-motor regulation, may offer a novel approach. Aim To evaluate the effect of a single functional neurology intervention on genital thermoregulation and ejaculatory latency in men with PE. Methods Fifty-two men diagnosed with PE participated in a pre–post intervention study. Each underwent a single session of functional neurology aimed at modulating nociceptor and mechanoreceptor pathways. Genital thermoregulation was assessed using infrared thermography, and ejaculatory function was measured via intravaginal ejaculatory latency time (IELT) and self-report at baseline, after the first post-treatment sexual encounter, and at 1-month follow-up. Statistical analyses included repeated-measures ANOVA, paired t-tests, Pearson correlation, and multiple regression. Outcomes Significant improvements in IELT and genital temperature were expected following the intervention, supporting its role in enhancing autonomic regulation and microvascular circulation. Results Intravaginal ejaculatory latency time increased significantly from a baseline of 20.4 ± 11.5 seconds to 439.2 ± 214.5 seconds post-treatment, with sustained effects at 1 month (498.0 ± 171.6 seconds; P < .001). Infrared thermography revealed significant increases in temperature in the glans, testicles, and abdomen (all P < .001), indicating enhanced peripheral circulation. Glans temperature change was the strongest predictor of testicular thermoregulation (β = 0.513, P < .001). Principal component analysis highlighted that glans and testicular areas contributed most to thermal variance post-treatment. A ≥1 °C increase in genital temperature was observed in 60% of participants. Clinical Implications Functional neurology may be a non-invasive, fast-acting intervention for improving ejaculatory control in PE by promoting autonomic balance and vascular function. Thermography proved useful as a biomarker for physiological changes and treatment efficacy. Strengths and Limitations This study is the first to evaluate thermographic and ejaculatory outcomes after a functional neurology intervention in PE. Strengths include objective and subjective measures, while limitations involve the lack of a control group, small sample size, and short-term follow-up. These results should be confirmed through randomized controlled trials. Conclusion A single session of functional neurology significantly improved both genital thermoregulation and ejaculatory latency in men with PE. These findings support the integration of neuromodulatory techniques into multidisciplinary strategies for sexual dysfunction treatment.
Is there a biological component in gender identity?
(Anales de pediatría, 2025) Sevane Fernández, Natalia; Fernández, Rosa; Gómez Balaguer, Marcelino; Mora, Mireia; Guerrero-Fernández, Julio; Moral Martos, Amadora
Introduction: Gender identity is each person’s internal sense of being a woman, a man, both, neither, or anywhere along the gender spectrum, which may (cisgender) or may not (transgender) coincide with the sex assigned at birth. The multiple difficulties experienced by transgender individuals constitutes a risk factor for mood disorders and self-harming behaviors. However, knowledge about biological influences on gender identity development has the potential to reduce the stigmatization of gender minorities. Materials and methods: We conducted a literature review of the available literature on the biological basis of gender identity, summarizing the main scientific evidence in the field in addition to its limitations. Results: A growing body of research supports that the broad spectrum that characterizes gender identity constitutes a multifactorial trait with a heritable component. At the neuroanatomical level, this model translates to the high variability observed in the degree of masculinization/feminization of different features within a single brain, with considerable overlap between different gender identities at the individual level. Hence, neither genetic variants nor neuroanatomic measures can be used to identify or predict an individual’s gender identity Conclusion: The evolutionary advantage of sexual reproduction lies in the huge increase in variation produced among individuals. The continuous distribution of gender identities in the population appears to be just one more aspect of sexual reproduction as a source of variability.
Ochratoxin A reduction in wine fermentation: evaluating the potential of Lachancea thermotolerans.
(AMB Express, 2025) Vicente Sánchez, Javier; Vidal, Daniel; Tesfaye, Wendu; Calderón, Fernando; García, Fernando; Benito, Santiago
Ochratoxin A is a mycotoxin commonly found in wine, primarily produced by fungal species from the Aspergillus and Penicillium genera. Due to its nephrotoxic, neurotoxic, immunotoxic, and carcinogenic properties, ochratoxin A contamination in wine is a significant concern for public health. This study investigates the potential of Lachancea thermotolerans in reducing ochratoxin A levels during wine fermentation, evaluating its fermentative performance and impact on key enological parameters. Fermentation trials with 32 L. thermotolerans strains demonstrated considerable variability in fermentation kinetics, ethanol production, and sugar consumption. The yeast exhibited strain-dependent variability in the production of organic acids, including succinic and lactic acid, leading to significant differences in total acidity and pH. Additionally, L. thermotolerans produced glycerol levels comparable to or exceeding those of Saccharomyces cerevisiae. The ability of L. thermotolerans to reduce ochratoxin A was highly strain-dependent, with reductions ranging widely. The most effective strains achieved ochratoxin A reductions exceeding those previously reported for S. cerevisiae. However, an inverse correlation was observed between ochratoxin A reduction and polyphenol retention, suggesting that strains with high ochratoxin A adsorption may also bind anthocyanins and polyphenols, affecting wine color and structure. These findings highlight L. thermotolerans as a promising non-Saccharomyces yeast for mitigating ochratoxin A contamination in wine while contributing positively to acidity modulation and sensory attributes. The study underscores the importance of strain selection to balance ochratoxin A detoxification with desirable enological properties, particularly in regions where contamination poses a significant challenge to wine safety and quality.
Tuberculosis caused by Mycobacterium caprae in a camel (Camelus dromedarius)
(BMC Veterinary Research, 2020) Infantes Lorenzo, José Antonio; Romero Martínez, Beatriz; Rodríguez Bertos, Antonio Manuel; Roy, Álvaro; Ortega, Javier; Juan Ferré, Lucía De; Moreno, Inmaculada; Domínguez, Mercedes; Domínguez Rodríguez, Lucas José; Bezos Garrido, Javier
Background: Animal tuberculosis (TB) is distributed worldwide and has a wide range of wild and domestic reservoirs. Few studies concerning TB in camelids have been published in the last decade, particularly as regards Old World Camelids (OWC), but the increase in reports of TB outbreaks in these species in recent years suggests a high susceptibility to the infection. Case presentation: We studied a dromedary camel (Camelus dromedarius) herd (n = 24) in which a Mycobacterium caprae infection was detected. The TB infection was confirmed in one animal at necropsy through the detection of TB lesions, mainly in the abdominal organs, and the subsequent isolation of M. caprae (SB0157 spoligotype). The whole herd was additionally tested using cellular and humoral based diagnostic techniques. The intradermal tuberculin test results were compared with those obtained using P22 ELISA for the detection of specific antibodies against the M. tuberculosis complex. The TB infected animal was a positive reactor to both the intradermal tuberculin tests and P22 ELISA, while the others were negative to all the diagnostic tests. Conclusion: The present study found M. caprae infection in OWC. This is the first report of M. caprae infection in an OWC not living in a zoo. Since the animal was born in the herd and fed with goat's milk, this practice was suspected to be the potential source of TB infection, which was not confirmed in the other animals present in the herd. Moreover, our results highlight that the intradermal tuberculin test and the P22 ELISA could be valuable tools for the diagnosis of TB in OWC.
