Understanding the factors that drive community‐wide assembly of plant‐pollinator systems along environmental gradients has considerable evolutionary, ecological and applied significance. Variation in thermal environments combined with intrinsic differences among pollinators in thermal biology have been proposed as drivers of community‐wide pollinat...

Bees are a diverse group with more than 1000 species known from the Iberian Peninsula. They have increasingly received special attention due to their important role as pollinators and providers of ecosystem services. In addition, various rapid human-induced environmental changes are leading to the decline of some of its populations. However, we kno...

The first records of Biastes emarginatus (Schenck, 1853) and Andrena (Andrena) clarkella (Kirby, 1802) for the Ibe-rian fauna are presented. Primeras citas de dos especies de abejas silvestres en la península ibérica (Hymenoptera, Apidae, Andrenidae) Resumen: Se presentan las primeras citas de Biastes emarginatus (Schenck, 1853) y Andrena (Andrena...

Se presenta y se ilustra la primera cita confirmada de Andrena (Ulandrena) polita Smith, 1857 en la Península Ibérica, especie cuya presencia se sospechaba pero aún no se había encontrado en este territorio. Se incluyen y se comentan además otras veintiseis especies de abejas silvestres nunca antes registradas en Asturias, de las cuales dieciséis s...

The present work assesses the diversity of pollinators in a pea (Pisum sativum L) crop from La Overuela (Valladolid, Spain). It is based on samplings carried out in 2008 that combined visual observations and the use of sweeping nets. The field work identified a total of 317 individuals, belonging to 25 genera and 42 species. The most abundant speci...

The previously unknown male of Andrena (Leucandrena) dinizi Warncke, 1975 is described. New data from Spain, the first ecological information, and the first photographs of the species in its natural habitat are also provided, as well as the first complete identification key to the West European species of the subgenus Leucandrena. Additionally, Nom...

The most suitable land for agricultural use has been gradually occupied by crops around the world. Large, uninterrupted croplands have been created, while disproportionate amounts of fertilizers, insecticides, fungicides and herbicides are applied on them. As a result, agricultural activity has a negative impact on biodiversity the ecological inten...

Starting in the 1950s, agricultural production has been remarkably intensified, resulting in modern management systems where a severe increase in field size led to an elimination of edges and other ecologically valuable structural elements. The resulting habitat loss caused dramatic changes in natural communities. The aim of this work is to test wh...

(1) Modern, intensive agricultural practices have been attributed to the loss of insect biodiversity and abundance in agroecosystems for the last 80 years. The aim of this work is to test whether there are statistically significant differences in insect abundance between different zones and over time on the vineyard field. (2) The study was carried...

New data about 34 species of clearwing moths collected or photographed all over mainland Spain, are reported. These records come from field photographs and non-systematic sampling carried out by the authors and their collaborators, and photographic data from citizen science web sites. With this set of data, numerous first provincial records are con...

La polinización del chirimoyo (Annona cherimola Miller) es uno de los aspectos más críticos de este cultivo debido a la dicogamia protogínica. Estudios muestran que el chirimoyo es polinizado por insectos silvestres, principalmente coleópteros. Sin embargo, en países donde el chirimoyo no crece naturalmente la polinización natural es deficiente. Po...

The present study analyses the effects of multifunctional areas (MA) for three years (2013-2015) on an intensive multi-crop farm in Portugal. The implementation of MA resulted in a wide range of enhancements in the insect community, such as significant effects as a reservoir, allowing an increase of 102.47% in the number of species and 97.64% of in...

Resultados del proyecto "Operación Polinizador" en Iberia como medida para mejorar la biodiversidad agrícola

Evolución de la biodiversidad de insectos en parcelas agrícolas de la Península Ibérica gracias al proyecto Operación Polinizador

A pesar de que España es uno de los países con mayor diversidad de polinizadores silvestres y, que de su conservación depende el futuro de nuestros cultivos y por tanto de nuestra alimentación, lo cierto es que hoy día seguimos sin conocer el estado de conservación de gran parte de esta fauna, una demanda histórica de la sociedad cien- tífica que s...

The exotic bee Megachile sculpturalis has colonized the European continent in the last decade, including some Mediterranean countries such as France and Italy. In summer 2018 it was recorded for the first time in Spain, from several sites in Catalonia (NE Iberian Peninsula). Here we give details on these first records and provide data on its biolog...

Bees belong to the order Hymenoptera, superfamily Apoidea, and constitute the monophyletic group Anthophila, originating from sphecoid wasps. There are about 20 000 species described in the world, 3370 in the western Palearctic and nearly 2000 in Europe. The Mediterranean basin is one of the areas with the richest diversity of bees, and in Spain mo...

Guide for the different pollination systems in the Iberian Peninsula and the Balearic and Canary Islands; keys to the orders and families of pollinating insects; diagnosis, biology (breeding) and floral preferences of pollinators; conservation measures for pollinators; importance of pollinators in vegetable and fruit crops.

This paper describes the main result produced by the ERABEE (Education & Research in Biosystems Engineering in Europe) Thematic Network. The ERABEE Thematic Network was a follow-up of a previous Thematic Network called USAEE (University Studies of Agricultural Engineering in Europe) and both were co-financed by the European Community in the framewo...

El futuro de estas explotaciones se ve ensombreci-do por las enfermedades, especialmente la tinta y el chancro, así como condicionado por un esque-ma de producción y distribución obsoleto * Urge una acción sanitaria en su conjunto que em-piece con la tala y retirada de los árboles afectados así como de la madera sana para que no sirva de propagació...

Osmoderma eremita (Coleoptera, Scarabaeidae, Cetoniinae) en Europa.¿ La investigación, el control y el desarrollo de estrategias de conservación de especies amenazadas en peligro de extinción están habitualmente confinadas por fronteras nacionales aunque sería más apropiado una perspectiva más global. En este trabajo se recogen datos sobre la prese...

We are 28 co-authors representing 25 European countries, who have collected data on a threatened beetle associated with tree hollows. Osmoderma eremita (SCOPOLI, 1763) (Coleoptera: Scarabaeidae). This project has arisen from our own initiative, based on the belief that entomology and nature conservation would do better with stronger co-operation be...

Research, monitoring and development of preservation strategies for threatened species are often limited by national borders even though a global perspective would be more appropriate. In this study, we collected data on the occurrence of a threatened beetle, Osmoderma eremita, associated with tree hollows in 2,142 localities from 33 countries in E...
