Además, son excelentes polinizadores y aportan numerosos servicios ecosistémicos fundamentales para la mayoría de ecosistemas terrestres. Debido a los diversos cambios ambientales inducidos por el ser humano, existen evidencias del declive de algunas de sus poblaciones para ciertas especies. Sin embargo, conocemos muy poco del estado de conservación de la mayoría de especies y de muchas de ellas ignoramos cuál es su distribución en la península ibérica. En este trabajo presentamos un esfuerzo colaborativo para crear una base de datos de ocurrencias de abejas que abarca la península ibérica e islas Baleares que permitirá resolver cuestiones como la distribución de las diferentes especies, preferencia de hábitat, fenología o tendencias históricas. En su versión actual, esta base de datos contiene un total de 87 684 registros de 923 especies recolectados entre 1830 y 2022, de los cuales un 87% presentan información georreferenciada. Para cada registro se incluye información relativa a la localidad de muestreo (89%), identificador y colector de la especie (64%), fecha de captura (54%) y planta donde se recolectó (20%). Creemos que esta base de datos es el punto de partida para conocer y conservar mejor la biodiversidad de abejas en la península ibérica e Islas Baleares.

- The biodiversity of terrestrial arthropods in AzoresPublication . Rego, Carla; Boieiro, Mário; Vieira, Virgílio; Borges, Paulo A. V.[…]. El Departamento de Biología de la Universidad de las Azores organizó un total de 15 expediciones científicas en el periodo 1977-2011, que dieron lugar a varias publicaciones incluyendo muchas sobre los Lepidoptera del archipiélago (Carneiro, 1982; Carvalho, 1982, 1984, 1992; Guimarães, 1982; Sousa, 1982, 1985a, b, 1991, 1999; Meyer, 1991a, b; Vieira & Pintureau, 1991, 1993; Henderickx, 1995; Vieira, 1997, 2003, 2009; Carvalho et al., 1999; Tennent & Sousa, 2003; Vieira et al., 2003a; Karsholt & Vieira, 2005; Vieira & Karsholt, 2010). Desde 1975 a 1990, se realizaron estudios autoecológicos centrados en plagas agrícolas y sus parásitos, tales como Mythimna unipuncta Haworth (Lepidoptera, Noctuidae) (Tavares, 1979; Vieira, 2000; Silva et al., 2003; Vieira et al., 2003b); Popillia japonica Newman (Coleoptera, Scarabaeidae) (Simões & Martins, 1985) y Trichogramma sp. (Hymenoptera, Trichogrammatidae) (Oliveira, 1987). No fue hasta 1990 cuando los estudios sobre la ecología de las comunidades de artrópodos comenzaron a desarrollarse en el archipiélago (por ejemplo Cruz De Boelpaepe, 1991; Braz, 1992; Garcia, 1992; Oliveira & Tavares, 1992; Borges, 1995) (Fig. 6). El archipiélago de las Azores fue objetivo de menos expediciones científicas entomológicas o de entomólogos individuales que Madeira o las Islas Canarias. Sin embargo, recientemente se ha incrementado el interés en su fauna y flora. Esto, junto con el establecimiento de una universidad en las Azores, hace posible la proliferación de un gran conjunto de trabajos entomológicos, lo que se manifiesta en un incremento en el número de publicaciones sobre la biogeografía, ecología, entomología aplicada, bioespeleología y sistemática de los artrópodos de Azores (ver Vieira & Borges, 1993; Borges & Vieira, 1994).

- The biodiversity of terrestrial arthropods in Madeira and Selvagens archipelagosPublication . Boieiro, Mário; Aguiar, António F.; Rego, Carla; Borges, Paulo A. V.; Serrano, Artur R. M.[…]. El número de taxones de artrópodos terrestres citado de los archipiélagos de Madeira y Salvajes es respectivamente 3.801 y 201, entre los que hay un número significativo de endemismos (Borges et al., 2008b) (ver Tabla I; Fig. 5; Lámina II). Madeira, la isla más grande, con una orografía compleja y con el número mayor de diferentes tipos de hábitat, destaca claramente sobre las otras islas de los dos archipiélagos tanto en la riqueza de especies como en el número de taxones endémicos. Sin embargo, también se debe tener en cuenta que la biodiversidad de Madeira se ha estudiado más en detalle, ya que esta isla ha sido el objetivo de varias expediciones de historia natural y muchas visitas de taxónomos expertos de todo el mundo (ver la sección anterior).

- Comparative phylogeography of endemic Azorean arthropodsPublication . Parmakelis, Aristeidis; Rigal, François; Mourikis, Thanos; Balanika, Katerina; Terzopoulou, Sofia; Rego, Carla; Amorim, Isabel R.; Crespo, Luís C.; Pereira, Fernando E. A.; Triantis, Kostas A.; Whittaker, Robert J.; Borges, Paulo A. V.BACKGROUND: For a remote oceanic archipelago of up to 8 Myr age, the Azores have a comparatively low level of endemism. We present an analysis of phylogeographic patterns of endemic Azorean island arthropods aimed at testing patterns of diversification in relation to the ontogeny of the archipelago, in order to distinguish between alternative models of evolutionary dynamics on islands. We collected individuals of six species (representing Araneae, Hemiptera and Coleoptera) from 16 forest fragments from 7 islands. Using three mtDNA markers, we analysed the distribution of genetic diversity within and between islands, inferred the differentiation time-frames and investigated the inter-island migration routes and colonization patterns. RESULTS: Each species exhibited very low levels of mtDNA divergence, both within and between islands. The two oldest islands were not strongly involved in the diffusion of genetic diversity within the archipelago. The most haplotype-rich islands varied according to species but the younger, central islands contributed the most to haplotype diversity. Colonization events both in concordance with and in contradiction to an inter-island progression rule were inferred, while a non-intuitive pattern of colonization from western to eastern islands was also inferred. CONCLUSIONS: The geological development of the Azores has followed a less tidy progression compared to classic hotspot archipelagos, and this is reflected in our findings. The study species appear to have been differentiating within the Azores for <2 Myr, a fraction of the apparent life span of the archipelago, which may indicate that extinction events linked to active volcanism have played an important role. Assuming that after each extinction event, colonization was initiated from a nearby island hosting derived haplotypes, the apparent age of species diversification in the archipelago would be moved closer to the present after each extinction-recolonization cycle. Exploiting these ideas, we propose a general model for future testing.
- Conservation status of the forest beetles (Insecta, Coleoptera) from Azores, PortugalPublication . Borges, Paulo A. V.; Lamelas López, Lucas; Amorim, Isabel R.; Danielczak, Anja; Nunes, Rui; Serrano, Artur R. M.; Boieiro, Mário; Rego, Carla; Hochkirch, Axel; Vieira, VirgílioBACKGROUND: Island biodiversity is under considerable pressure due to the ongoing threats of invasive alien species, land use change or climate change. The few remnants of Azorean native forests harbour a unique set of endemic beetles, some of them possibly already extinct or under severe long term threat due to the small areas of the remaining habitats or climatic changes. In this contribution we present the IUCN Red List profiles of 54 forest adapted beetle species endemic to the Azorean archipelago, including species belonging to four speciose families: Zopheridae (12 species), Carabidae (11 species), Curculionidae (11 species) and Staphylinidae (10 species). NEW INFORMATION: Most species have a restricted distribution (i.e. 66% occur in only one island) and a very small extent of occurrence (EOO) and area of occupancy (AOO). Also common to most of the species is the severe fragmentation of their populations, and a continuing decline in EOO, AOO, habitat quality, number of locations and subpopulations caused by the ongoing threat from pasture intensification, forestry, invasive species and future climatic changes. Therefore, we suggest as future measures of conservation: (1) a long-term monitoring plan for the species; (2) control of invasive species; (3) species-specific conservation action for the most highly threatened species.
- Drivers of Insect Community Change along the Margins of Mountain Streams in Serra da Estrela Natural Park (Portugal)Publication . Ceia-Hasse, Ana; Boieiro, Mário; Soares, Albano; Antunes, Sandra; Figueiredo, Hugo; Rego, Carla; Borges, Paulo A. V.; Conde, José; Serrano, Artur R. M.Mountain ecosystems are important biodiversity hotspots and valuable natural laboratories to study community assembly processes. Here, we analyze the diversity patterns of butterflies and odonates in a mountainous area of high conservation value—Serra da Estrela Natural Park (Portugal)—and we assess the drivers of community change for each of the two insect groups. The butterflies and odonates were sampled along 150 m transects near the margins of three mountain streams, at three elevation levels (500, 1000, and 1500 m). We found no significant differences in odonate species richness between elevations, but marginal differences (p = 0.058) were found for butterflies due to the lower number of species at high altitudes. Both insect groups showed significant differences in beta diversity (βtotal) between elevations, with species richness differences being the most important component for odonates (βrich = 55.2%), while species replacement drove the changes between butterfly assemblages (βrepl = 60.3%). Climatic factors, particularly those depicting harsher conditions of temperature and precipitation, were the best predictors of total beta diversity (βtotal) and its components (βrich, βrepl) for the two study groups. The study of insect biodiversity patterns in mountain ecosystems and of the role played by different predictors contribute to further our understanding on the community assembly processes and may help to better predict environmental change impacts on mountain biodiversity.
- Formiga-argentina um pequeno invasor…mas com grande impactoPublication . Boieiro, Mário; Rego, Carla; Borges, Paulo A. V.A FORMIGA-ARGENTINA - Linepithema humile (Mayr, 1868) - é considerada uma das 100 piores espécies invasoras a escala Global por ser responsável por impactos severos na biodiversidade e nos processos ecológicos, tanto em áreas continentais como nas ilhas. Esta espécie é originaria da América do Sul e foi introduzida no continente Europeu durante o século XIX, tendo o primeiro registo sido feito de Portugal. No espaço de algumas décadas sucederam-se os primeiros registos desta espécie noutros países europeus (respetivamente em Itália, Franca, Espanha, Bósnia, Mónaco, …), estando atualmente bem distribuída neste continente.

- The fruit flies (Diptera, Tephritidae) of the Madeira archipelago with the description of a new Oedosphenella FreyPublication . Penado, Andreia; Smit, John T.; Aguiar, António F.; Cravo, Délia; Rego, Carla; Santos, Renata; Boieiro, MárioA checklist of the tephritid fauna (Diptera: Tephritidae) from Madeira archipelago is presented, including 17 known species and new distribution records for Porto Santo and Desertas Islands. An identification key to Madeira Tephritidae species with detailed illustrations is also provided. A new species of Oedosphenella Frey 1936, discovered in Madeira Island in 2004, is described as Oedosphenella bob sp. n. This genus is redefined and a key to the known species is provided. Comparative morphological analysis revealed that Bevismyia basuto Munro 1957 from Malawi should be included in the genus Oedosphenella. Therefore, we consider the genus name Oedosphenella Frey 1936 to be a senior synonym of Bevismyia Munro 1957 syn.n.
- Habitat filtering and inferred dispersal ability condition across‐scale species turnover and rarity in Macaronesian island spider assemblagesPublication . Malumbres-Olarte, Jagoba; Rigal, François; Girardello, Marco; Cardoso, Pedro; Crespo, Luís C.; Amorim, Isabel R.; Arnedo, Miquel A.; Boieiro, Mário; Carvalho, José Carlos; Carvalho, Rui; Gabriel, Rosalina; Lamelas-López, Lucas; López, Heriberto; Paulo, Octávio S.; Pereira, Fernando; Pérez‐Delgado, Antonio J.; Rego, Carla; Romeiras, Maria M.; Ros-Prieto, Alejandra; Oromí, Pedro; Vieira, Ana; Emerson, Brent C.; Borges, Paulo A. V.AIM: Habitat diversity has been linked to the diversity and structure of island communities, however, little is known about patterns and processes within habitats. Here we aim to determine the contributions of habitat type and inferred dispersal frequency to the differences in taxonomic structure between assemblages in the same island habitat. LOCATION: The Macaronesian archipelagos (Azores, Madeira, the Canary Islands and Cabo Verde). TAXON: Spiders (Araneae). METHODS: We established forest and dry habitat sites (each with five plots) on two islands per archipelago. We collected spiders using standardised sampling protocols. We tested the differences in beta diversity separately for each habitat and for each inferred category of ballooning (an aerial dispersal strategy) frequency across geographic scales through nested non-parametric permutational multivariate analyses of variance. We then tested whether ballooning and habitat influenced heterogeneity in species composition (dispersion in beta diversity) in the two habitat types. We analysed the effects of habitat and ballooning on species abundance distribution (SAD) and rarity by fitting Gambin models and evaluating the contribution of ballooning categories to SAD. RESULTS: Communities of the same archipelago and habitat were taxonomically more similar, and beta diversity increased with geographic scale, being greater in dry habitats. There was greater species replacement among assemblages in dry habitats than in forests, with greater differences for rare ballooners. There were no differences in SAD between habitats although dry habitat sites seemed to harbour more species with low abundances (rare species) than forests. MAIN CONCLUSIONS: Habitat type does not only condition the differences between spider assemblages of the same habitat but also the scale at which they occur. These differences may be determined by the heterogeneity in the physical structure of each habitat as well as how much this structure facilitates aerial dispersal (ballooning), and should be considered in theories/hypotheses on island community assembly as well as in conservation strategies.
- Hsp70 protein levels and thermotolerance in Drosophila subobscura: a reassessment of the thermal co-adaptation hypothesis.Publication . Calabria, G.; Dolgova, O.; Rego, Carla; Castaneda, L.E.; Rezende, E.L.; Balanyà, J.; Pascual, M.; Sørensen, J.G.; Loeschcke, V.; Santos, M.Theory predicts that geographic variation in traits and genes associated with climatic adaptation may be initially driven by the correlated evolution of thermal preference and thermal sensitivity. This assumes that an organism’s preferred body temperature corresponds with the thermal optimum in which performance is maximized; hence, shifts in thermal preferences affect the subsequent evolution of thermal-related traits. Drosophila subobscura evolved worldwide latitudinal clines in several traits including chromosome inversion frequencies, with some polymorphic inversions being apparently associated with thermal preference and thermal tolerance. Here we show that flies carrying the warm-climate chromosome arrangement O3+4 have higher basal protein levels of Hsp70 than their cold-climate Ost counterparts, but this difference disappears after heat hardening. O3+4 carriers are also more heat tolerant, although it is difficult to conclude from our results that this is causally linked to their higher basal levels of Hsp70. The observed patterns are consistent with the thermal co-adaptation hypothesis and suggest that the interplay between behaviour and physiology underlies latitudinal and seasonal shifts in inversion frequencies.
