Item Wing morphometrics for identification of forensically important blowflies (Diptera: Calliphoridae) in Iberian Peninsula(Journal of forensic and legal medicine, 2020) Jiménez-Martín, Francisco José; Cabrero Sañudo, Francisco José; Martínez-Sánchez, AnabelCalliphoridae is a family of Diptera of great forensic interest because some of its species belong to the sarcosaprophagous diptera community, as their larvae are necrophagous or necrophilous. In the Iberian Peninsula there are six species that stand out, as they are the first insects to arrive at carrion: Calliphora vicina, Calliphora vomitoria, Lucilia sericata, Lucilia caesar, Chrysomya albiceps and Chrysomya megacephala. To differentiate among these blowflies, we compared the value of using traditional and geometric morphometrics by performing a morphometric analysis of the wings (shape and size). A total of 600 individuals were considered, segregated by species and sex equally. Seventeen landmarks per wing were recognized, and then centroid size and shape analyses were performed using geometric morphometrics, and size using traditional morphometrics, to identify species and sex. The results showed differences in shape among the species and it was found that landmarks 2 to 11 were the most variable, while the landmarks located at the base of the wings were relatively stable. However, according to both traditional and geometric morphometrics, no significant differences were found among species in wing size (Calliphora vicina, Chrysomya megacephala and Lucilia caesar were indistinguishable), but females were larger than males (except for the two Chrysomya species). Our results indicate that the use of geometric morphometrics to analyze wing configuration (shape) is an easy-to-use tool that helps to distinguish among common blowfly species of forensic importance.Item Influence of environmental temperature and humidity on questing ticks in central Spain(Experimental and Applied Acarology, 2017) Requena García, F.; Cabrero Sañudo, Francisco José; Olmeda García, Ángeles Sonia; González, Julia; Valcárcel, F.Ticks are important ectoparasites and vectors of the pathogens that cause disease in humans and animals. At a natural reserve in Ciudad Real (Spain), an uncontrollable infestation of wild animals with Hyalomma lusitanicum (Koch) has been reported by some game reserve owners. Many questions about distribution, abundance, and phenology of this tick in this area remain unanswered. The aim of this study was to determine if temperature and relative humidity affect the questing tick’s activity in four species of ticks in a mesoMediterranean area, especially that of H. lusitanicum. Data for tick populations in six selected sampling sites every month, between January 2007 and December 2013 were used. Temperature and humidity values (ground and environmental) were recorded. The sampling effort, the similarity between sites, and the phenology of the species were analyzed. Effects of environmental variables on tick’s activity were assessed by general linear models (GLM) whereas the comparative importance of variables was measured by hierarchical variance partitioning. Hyalomma lusitanicum represented 96.3% of the four species of ticks collected. Spring and summer months presented a higher activity of ticks, than autumn and winter months. In general, humidity variables were negatively related to the activity of ticks, whereas temperature variables were positively related. Our results suggest that the highest activity in the area is produced by biological characteristics of H. lusitanicum; being temperature and humidity the most important environmental factors influencing the abundance of this species in the region.Item Climate as a possible driver of gall morphology in the chestnut pest Dryocosmus kuriphilus across Spanish invaded areas(Bulletin of Entomological Research, 2020) Gil-Tapetado, Diego; Cabrero Sañudo, Francisco José; Polidori, Carlo; Gómez Sánchez, José Francisco; Nieves-Aldrey, José LuisThe alien cynipid wasp Dryocosmus kuriphilus Yasumatsu, 1951 is a serious pest of chestnuts (Castanea spp.) in Japan, North America and Europe, causing fruit losses while inducing galls in buds. While D. kuriphilus galls have a recognizable and roughly invariable globular shape, their size varies, reaching up to 4 cm in diameter. Among other factors, such variation may depend on different climatic conditions in different attacked areas. Here, we sampled and measured 375 D. kuriphilus galls from 25 localities throughout the Iberian Peninsula, including both cold and rainy northern (Eurosiberian) areas and warm and dry central-southern (Mediterranean) areas, to test the effects of climate and geographical location on gall morphology. The analyses indicate that gall mass and volume follow a pattern that can be associated with a climatic cline. In particular, the Eurosiberian galls were smaller than the Mediterranean galls according to differences in climatic conditions. In the southern areas, the greater insolation regime does not allow the chestnut trees to be distributed at lower altitudes, but the high rainfall and humidity regime of the mountain enclaves allow their presence. These conditions of insolation and precipitation seem to influence the morphological characteristics of the galls of D. kuriphilus.- Project number: 232
Item Actitudes y conocimiento de la Biodiversidad de la comunidad universitaria(2021) Cabrero Sañudo, Francisco José; Aguirre de Miguel, José Ignacio; Banda Rueda, Eva Isabel; Gómez Sánchez, Jose Francisco; Molina Abril, José Antonio; Grzechnik, Sandra; Gil Tapetado, Diego; Hernández Téllez, Irene; López García, Alejandro; Herrero Sanz, Aida; Montero Delgado, Jesús María; Hernández de Miguel, José María; Alonso Martínez, PuyProyecto de Innovación Docente 232 de la convocatoria 2019/2020.

Item Identification of the intermediate host of Gongylonema sp., the etiological agent of the necrotic oropharyngeal disease of the Scops owl (Otus scops)(Parasitology International, 2021) Lopes, Fatima; Esperón, Fernando; Bravo-Barriga, D.; Frontera, E.; Cabrero Sañudo, Francisco José; Gil Tapetado, Diego; Orejas, P.; Alonso, R.Since 1997, fledgling Scops owls (Chordata: Strigidae) have been brought to the Brinzal Owl Rescue Centre (Madrid, Spain) with severe lesions in their oral cavities. Lesions consist of the presence of proliferative necrotic material in the oral cavity resulting in white plaques, which can lead to death by starvation. This disease has been detected in owls only within the limits of the city of Madrid. The etiologic agent has been identified as Gongylonema sp. (Nematoda: Spirurida), a nematode genus that includes a coprophagous arthropod as intermediate host in its cycle. The aim of this study was to identify the intermediate host of the parasite. Our work was structured in four component phases: i) Diet study of newborn chicks; ii) trapping arthropods that could be intermediate hosts; iii) molecular detection of the parasite in the selected arthropods: and iv) molecular characterization of the detected parasites by amplifying the cox1 gene. Four male owls were radio-tagged in order to locate their nests and a camera trap was placed to identify the prey brought to the owlets. Secondly, the arthropods present in the hunting areas of the owls were sampled, identified and analyzed by real time PCR (rtPCR). Only oriental cockroaches, B. orientalis (Arthropoda: Blattodea), were positive by rtPCR detection of Gongylonema sp. (66.7%). The nematodes obtained from cockroaches had a 99.8% identity of the cox1 gene with the Gongylonema sp. isolated for the first time in a Scops owl. Furthermore, these sequences only showed an <89% identity with all the other Gongylonema sequences available in the GenBank database. We conclude that the oriental cockroach should be considered as an intermediate host of the etiologic agent of NOD.Item Aridity could have driven the local extinction of a common and multivoltine butterfly(Ecological Entomology, 2022) Gil Tapetado, Diego; Soria, Carmen D.; Gómez, Jose F.; Sesma, Jose Manuel; Cabrero Sañudo, Francisco José1.Identifying which species are being negatively impacted by climate change and the mechanisms driving their decline is essential to effectively protect biodiversity. 2.Coenonympha pamphilus is a common and generalist butterfly, widely distributed throughout the Western Palearctic, being multivoltine in southern Europe. Previous studies indicate that it will not be substantially affected by climate change; however, it has seemingly disappeared from the southeast of the Iberian Peninsula in the last decades. 3. Here, we aim to determine if it has effectively disappeared from this area, as well as identify the environmental conditions limiting its distribution and the potential causes behind this a priori local extinction. 4.We downloaded all the occurrence records of C. pamphilus and analysed their spatial and temporal trends. To identify the climatic variables driving the distribution of this butterfly in the Iberian Peninsula, we performed an ensemble species distribution model (SDM), combining 600 individual models produced with 6 algorithms. 5.We confirmed that C. pamphilus has not been observed in the southeast of the Iberian Peninsula since 2008. Aridity was the main factor limiting the distribution of C. pamphilus in our ensemble SDM, with areas with high aridity being unsuitable for this species. 6. We hypothesise that multivoltinism is the mechanism driving this local extirpation, as high aridity is causing host plants (Poaceae) to wither prematurely, precluding the development of the second and/or third generations of the butterfly. Even though generalist species are theoretically more resilient to climate change, other traits such as multivoltinism may increase their vulnerability and need to be further investigated.- Project number: 286

Item Across the firefly-verse: comparison of niche suitability of an exotic firefly in its native and colonized range(Journal of Insect Conservation, 2023) Gil Tapetado, Diego; Koken, Marcel; De Cock, Raphaël; Gómez Sánchez, José Francisco; Cabrero Sañudo, Francisco José; Polidori, CarloPhotinus signaticollis Blanchard, 1846 (Coleoptera: Lampyridae) is a firefly native to South America and recently established in Europe. Since 2016, this firefly has colonized the northeastern part of the Iberian Peninsula and crossed the Pyrenees to reach southern France in 2019. The larvae of this firefly feed on earthworms, so a high density of this species could negatively impact this key group in soil processes and agriculture. The precise extent of colonization, the environmental niche and the potential range expansion in non-native areas are currently unknown. Using species distribution models, we have found the high suitability areas across Europe where P. signaticollis may become established if introduced. Interestingly, using only South American records and associated conditions modelling it can be strongly predicted where the species is currently found in Europe. Despite a few propagules of P. signaticollis detected in very unsuitable areas of Spain were no longer detected after their initial observation, the climatic niche overlap between South America and Europe populations appeared to be very low. In our case, this pattern is more likely to reflect a high unfilled niche rather than a niche expansion or niche shift, because many occupied areas in South America possess a climate not occurring in Europe. Among the considered variables, we furthermore found that only the temperature seasonality appeared to be the same in both native and European areas and relevant in the models, suggesting that it may represent the main limiting factor for establishing this firefly.Item Disease prevalence in an urban raptor related to pest species: the case of Eurasian Scops Owl Otus scops infection by Gongylonema sp.(Ibis: International Journal of Avian Science, 2023) Hernández-Téllez, Irene; Martínez-Miranzo, Beatriz; Gil Tapeado, Diego; Lopes, Francisca; Esperón, Fernando; Cabrero Sañudo, Francisco José; Aguirre De Miguel, José IgnacioUrbanization is often associated with homogenization, including the homogenization of biodiversity and overpopulation by generalist species that can change community and disease dynamics. In Madrid, nestlings of Eurasian Scops Owl Otus scops frequently suffer necrotic oropharyngeal disease as a result of infection by Gongylonema sp., a parasitic nematode transmitted by adult owls to their offspring through the diet, more specifically through consumption of a pest species: the oriental cockroach Blatta orientalis. We studied how the presence of cockroaches and owl infection rates are affected by urban features such as green areas. We found that a higher number of birds were affected by the parasite in the initial period of the breeding season and in areas with greater surface area of green spaces. We suggest that urban management should promote the diversity of insects in green areas so that the owls diversify their dietary offer to their offspring, to reduce the prevalence of the disease and improve their breeding success in the city of Madrid, as this problem has not yet been described in other cities.- Project number: PIMCD412/23-24
Item Universos interdisciplinares (entre la biología y el arte)(2024) Castelo Sardina, Luis; San Frutos Forja, Manuel; Gómez Isla, José; Legido García, María Victoria; Álvarez Couso, Pablo; Gómez Tribello, Pablo; López Collar, Diego; Moreno Diz, Lucía; Gil Tapetado, Diego; Cabrero Sañudo, Francisco José; Acevedo Ramos, Fernando; Atienza Alonso, Javier; Grzechnick, Sandra; Muñoz González, Francisco Javier; Villar Soblechero, David; Castelo Sardina, LuisAnte la alarmante pérdida de biodiversidad observada en las últimas décadas por los expertos en entomología, el presente proyecto propone, a través de la tecnología digital de producción de imágenes, aportar un mayor conocimiento de esta problemática, tanto entre docentes como entre estudiantes de Bellas Artes y Biología, y servir como herramienta para proporcionar contenidos didácticos/expositivos a través de creaciones digitales en alta resolución. El proyecto se propone colaborar entre dos departamentos de la UCM, uno en la facultad de Bellas Artes y el otro en la Facultad de Ciencias Biológicas. Concretamente, los departamentos colaboradores serán el Departamento de Diseño e Imagen y el Departamento de Biodiversidad, Ecología y Evolución. La intención última será la de crear recursos didácticos, y también investigadores, obtenidos a través de la tecnología digital de generación de imágenes fotográficas por un sistema de apilamiento de enfoque. Estas imágenes serán generadas digitalmente mediante la reproducción de especímenes pertenecientes a la colección de entomología que alberga la facultad de Ciencias Biológicas de la UCM. El apilamiento de enfoque (focus stacking) es un procedimiento fotográfico novedoso, utilizado esencialmente en ciencia en el ámbito de la macrofotografía y la microscopía óptica. Mediante un complejo procesamiento digital y un software específico de tratamiento de imágenes se consiguen agrupar múltiples fotografías de un mismo motivo, pequeño y cercano al objetivo de la cámara, que han sido obtenidas enfocando a distintos planos del mismo y con profundidades de campo muy limitadas. La finalidad del procedimiento consiste en crear una única representación gráfica que tenga una profundidad de campo infinitamente mayor que cualquiera de las fotos tomadas de forma individual. Esta representación se consigue mediante la combinación selectiva de todos los planos enfocados del objeto, integrados ahora en una sola imagen. De este modo, y gracias a la agrupación y combinación digital de dichas imágenes, el motivo fotografiado puede gozar de la máxima profundidad de campo, desde su primer hasta su último término. Así mismo, y de determinados especímenes tipo, se realizará, a través de fotogrametría, una imagen múltiple y tridimensional que nos permitirá realizar modelos en 3D.
