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 José
1.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.
Torymus sinensis against the invasive chestnut gall wasp: Evaluating the physiological host range and hybridization risks of a classical biological control agent
(Biological Control, 2023) Gil Tapetado, Diego; López-Estrada, Karen ; Jiménez Ruiz, Yolanda; Cabrero Sañudo, Francisco José; Gómez Sánchez, José Francisco; Durán Montes, Patrica; Rey del Castillo, Carmen; Rodríguez-Rojo, Pilar; Polidori, Carlo; Nieves-Aldrey, Jose Luis
Background: a common strategy to limit the negative impact of biological invasions is biological control through the release of specialized alien natural enemies. However, biological control plans are not without risks, which include parasitism of native hosts and hybridization with related native species, particularly those that are potential natural enemies of the invasive species. Here, we evaluate these potential risks resulting from the introduction of the parasitoid wasp Torymus sinensis (Hymenoptera: Torymidae) in Europe to control the invasive Asian chestnut gall wasp Dryocosmus kuriphilus (Hymenoptera: Cynipidae). Results: we found that, under laboratory conditions, the physiological host range of T. sinensis includes several native non-target species of Cynipidae, with oviposition observed on the galls of 8 of the 11 species tested. However, physiological host range of T. sinensis appears to be limited under field conditions, as we observed only one parasitized gall of Andricus curvator in the field. Regarding hybridization, inter-species mating between T. sinensis and its phylogenetically closest native Torymus species was not observed in the laboratory. Moreover, discordance between nuclear (ITS2) and mitochondrial (coxI) data does not support the presence of genetic introgression, suggesting that hybridization between T. sinensis and native Torymus species does not occur. In addition, we cite and discuss the unexpected presence of one individual of the related alien species Torymus beneficus in Spain. Conclusion: our results suggest that T. sinensis may negatively impact several non-target species, highlighting the need for careful monitoring of the extent of such undesired behaviour and its effects on the native fauna.
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, Anabel
Calliphoridae 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.
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.
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 Luis
The 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.
Distribution and dispersal of the invasive Asian chestnut gall wasp, Dryocosmus kuriphilus (Hymenoptera: Cynipidae), across the heterogeneous landscape of the Iberian Peninsula
(European Journal of Entomology, 2018) Gil Tapetado, Diego; Gómez Sánchez, José Francisco; Cabrero Sañudo, Francisco José; Nieves-Aldrey, Jose Luis
Dryocosmus kuriphilus (Hymenoptera: Cynipidae), also known as the Asian chestnut gall wasp, is a non-native invasive species that has recently appeared in many regions of Europe, including the Iberian Peninsula. This species is an important pest of chestnut trees in several regions and is of concern for foresters in these areas. The results of this research revealed 14 different hotspots of infestation of D. kuriphilus and resulted in the development of models that predict the distribution of D. kuriphilus in Spain over the next 37 years (2019-2055). These results indicate a rapid spread in all Spanish chestnut forests and identify areas that are theoretically highly suitable and susceptible to colonization by this cynipid based on predictions of three different niche models. Although D. kuriphilus is able to induce galls on all chestnut trees, the models indicate that there are differences in the suitability of the different regions for this species. This differential suitability results in some areas having better environmental conditions than others for D. kuriphilus, which is a factor that should be taken into account in its management and biological control. This study of the current distribution, patterns of dispersal using GIS and potentially suitable areas for D. kuriphilus, using niche models will assist in the management and control of this pest in Spain.
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 Ignacio
Urbanization 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.

Ante 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.
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, Carlo
Photinus 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.
