Hypoponera ragusai (Emery, 1895) a cavernicolous ant new for the Iberian Peninsula (Hymenoptera, Formicidae)
Tinaut, Alberto
Graellsia , 2001,
Abstract: In this study, we cite Hypoponera ragusai for the first time in the Iberian Peninsula, this species being distributed throughout the North Africa, southern Italy and southern France. This species shows cavernicolous behaviour in Sicily. In Spain the only three localities known until the moment are also cavities, one in the province of Almería (Sima Termal), other in the province of Málaga (Cueva de Nerja) and the other in the province of Granada (Cueva del Barranco I ate). The population studied in the Cueva del Barranco I ate presents, throughout the year, three castes typical of formicids —that is, workers, females and males— in addition to eggs and larvae. The constant presence of brood, aptery in the females and males, as well as their limitation to the cavernicolous environment raise the possibility that this might even be a species, or at least populations, that are strictly cavedwelling, considerations discussed in depth in this paper. En este artículo se cita por primera vez para la península Ibérica a Hypoponera ragusai, especie distribuida por el norte de áfrica, sur de Italia y sur de Francia. Esta especie se comporta como cavernícola en Sicilia. Las tres únicas localidades conocidas hasta el momento para Andalucía son también cavidades, una en la provincia de Almería (Sima Termal), otra en la provincia de Málaga (Cueva de Nerja) y la otra de la provincia de Granada (Cueva del Barranco I ate). La población estudiada en la Cueva del Barranco I ate presenta a lo largo de todo el a o las tres castas típicas de los formícidos, es decir, obreras, hembras y machos, además de huevos y larvas. La presencia constante de prole, el apterismo de las hembras y de los machos, así como su limitación al medio cavernícola nos hace plantearnos la posibilidad de que se trate efectivamente de una especie, o al menos de unas poblaciones, estrictamente troglobias, lo que se discute en este artículo.
A new species of the genus Rossomyrmex Arnoldi, 1928 from Turkey (Hymenoptera. Formicidae)
Tinaut, A.
Graellsia , 2007,
Abstract: A new species, Rossomyrmex anatolicus, is described from the Anatolian plains (Turkey). Although it is very similar to R. proformicarum because of the abundant pilosity, it can be distinguished by the petiole, which gradually narrows towards the apex. This character, together with the high number of hairs, can be used, also, to differentiate it from R. minuchae. The geographical distribution of the genus Rossomyrmex is discussed and compared with other taxa that also show disjointed distributions. Se describe Rossomyrmex anatolicus, nueva especie encontrada en las llanuras de Anatolia (Turquía). Muy parecida a R. proformicarum por la abundante pilosidad, se diferencia de ésta por el peciolo, que se estrecha gradualmente hasta el ápice. Este mismo carácter, junto con la pilosidad permiten diferenciarla de R. minuchae. Se discute la distribución geográfica del género Rossomyrmex y se compara con la de otros taxones que muestran también distribución disjunta.

Las hormigas (Hymenoptera, Formicidae) asociadas a pulgones (Hemiptera, Aphididae) en la provincia de Valencia
Suay-Cano, V. A.,Tinaut, Alberto,Selfa, Jesús
Graellsia , 2002,
Abstract: Twenty-six species of ants associated with aphids, belonging to twelve genera, are collected. Three subfamilies are identified, being the Formicinae the more represented about number of samples, genera and species. On the other hand, Lasius niger has been the species that is found with a more number of aphids (fifty eight species), and it seems to be the ant with a more capacity to establish associations with the different species of aphids. 224 different associations between the ants and the aphids are established and 164 of them are not recorded in the bibliography consulted for Spain. Se han recogido veintiséis especies de hormigas asociadas a pulgones, pertenecientes a doce géneros. De las tres subfamilias identificadas, Formicinae ha sido la más representada en cuanto a número de muestras, géneros y especies. Lasius niger, por otra parte, ha sido la especie que se ha encontrado junto a un mayor número de pulgones (cincuenta y ocho especies), demostrando ser la hormiga con mayor capacidad para establecer asociaciones con las diferentes especies de pulgones. Se han establecido un total de 224 asociaciones diferentes entre las hormigas y los áfidos, de las cuales 164 no se han encontrado citadas en la bibliografía consultada para Espa a.

Ecología Aplicada , 2004,
Abstract: Se han estudiado los nidos de hormigas presentes en tres olivares con diferente manejo agronómico, ubicados a 20 km de la ciudad de Granada (Espa a). En cada olivar se observó el área correspondiente a 60 árboles (seis hileras contiguas de 10 árboles) y los cinco transectos de 100 m de longitud por un metro de ancho en las calles, entre las hileras de árboles. En el suelo bajo la copa de cada árbol y en las calles se determinó el número de los nidos en actividad de cada especie, en un área total de 540 m2 (9 m2/árbol) y 500m2 (100 m2/calle) respectivamente, con una duración de 15 minutos por árbol y por transecto entre las 9:00 y 14:00 horas. También se determinó el número de nidos en el tronco del árbol mediante observación de los mismos en 5 minutos, durante los meses de Mayo, Julio y Septiembre de 1997 y 1998. Los resultados indican que la perturbación producida por las prácticas agronómicas afecta el número y abundancia de los hormigueros en el suelo bajo el árbol y en las calles. Los olivares con manejo ecológico (Arenales) y abandonado (Colomera 2) presentaron significativamente mayor densidad de nidos en el suelo bajo el árbol que el olivar con aplicación de plaguicidas (Colomera 1). Este último no presentó hormigueros en las calles. La perturbación por laboreo y aplicación de plaguicidas en el olivar abandonado tuvo como respuesta el aumento de nidos por gemación y la disminución posterior de los mismos. En los árboles de 80 a os (Arenales) se presentan hormigueros en el tronco y no en los de 25 a os.

Ecología Aplicada , 2005,
Abstract: El estudio se realizó en tres olivares con diferente manejo agronómico, a 20 km de la ciudad de Granada. En cada olivar se observó el área correspondiente a 60 árboles (seis hileras contiguas de 10 árboles) y cinco transectos de 100 m de longitud por un metro de ancho en las calles, entre las hileras de árboles. En el suelo bajo la copa de cada árbol y en las calles se determinó la ubicación de los hormigueros, en un área total de 540 m2 (9 m2/árbol) y 500m2 (100 m2/calle) respectivamente. Se procedió al mapeo de los nidos durante los meses de Mayo, Julio y Septiembre de 1997 y Mayo de 1998 y a medir la distancia entre nidos en los tres meses de 1997. La determinación de la distribución de los hormigueros se realizó por medio del método del vecino más próximo. Los resultados indican que la distribución de los nidos de las principales especies (Aphaenogaster senilis, Messor barbarus, Crematogaster auberti, Crematogaster sordidula, Solenopsis latro, Tetramorium semilaeve, Tapinoma nigerrima, Plagiolepis pygmaea, Cataglyphis rosenhaueri) y del total de los nidos en el olivar, corresponde en general a una distribución regular que pasa al azar cuando la densidad disminuye. Los Indices de Permanencia intraanual de los hormigueros fueron bajos (0.0 a 57.1%) y los interanual con valor cero. Los Indices de Renovación de los nidos variaron entre 0% y 100%.
Taxonomy and distribution of Formica dusmeti Emery, 1909 and of F. frontalis Santschi, 1919 (Hymenoptera, Formicidae)
Tinaut, A.,Martínez-Ibá?ez, Ma. D.
Graellsia , 1998,
Abstract: In the present work, we indicate the distribution of and taxonomic differences between Formica dusmeti and Formica frontalis (stat. n.). Morphological differences include a total absence of hairs in F. dusmeti as opposed to uniformly scattered hairs in F. frontalis. These two species have similar coloration and hairless scapes and eyes. In addition, we describe the male and female of F. frontalis, a species that was considered until now to be a subspecies of F. truncorum. We consider F. frontalis to be a separate species from F. truncorum, differentiated by a lack of hairs on the eyes, scapes and genae in the workers of the former. The males of F. frontalis are distinguished from F. truncorum by hairless eyes and scapes. Finally, a key has been formulated for the workers in the rufa, sanguinea and exsecta groups of the genus Formica in the Iberian Peninsula. En este trabajo se se alan las diferencias existentes entre Formica dusmeti y Formica frontalis (stat. n.) y su distribución. Estas diferencias estriban en la ausencia total de quetas en F. dusmeti y la presencia de numerosas quetas uniformemente distribuidas en F. frontalis. Estas dos especies presentan en común la coloración y la ausencia de quetas en escapo y ojos. Describimos el macho y la hembra de F. frontalis, especie que era considerada hasta ahora como subespecie de F. truncorum. En este artículo la elevamos a especie y la diferenciamos de F. truncorum por la ausencia de quetas en los ojos, escapos y genas de las obreras. Los machos se diferencian también por la ausencia de quetas en ojos y escapos. Por último se realiza una clave para las obreras de la Península Ibérica de las especies de Formica de los grupos rufa, sanguinea y exsecta.
Rossomyrmex, the Slave-Maker Ants from the Arid Steppe Environments

Abstract: The host-parasite genera Proformica-Rossomyrmex present four pairs of species with a very wide range of distribution from China to Southeastern Spain, from huge extended plains to the top of high mountains. Here we review (1) the published data on these pairs in comparison to other slave-makers; (2) the different dispersal ability in hosts and parasites inferred from genetics (chance of migration conditions the evolutionary potential of the species); (3) the evolutionary potential of host and parasite determining the coevolutionary process in each host-parasite system that we treat to define using cuticular chemical data. We find a lower evolutionary potential in parasites than in hosts in fragmented populations, where selective pressures give advantage to a limited female parasite migration due to uncertainty of locating a host nest. A similar evolutionary potential is detected for hosts and parasites when the finding of host nests is likely (i.e., in continuous and extended populations). Moreover, some level of local adaptation at CHC profiles between host and parasite exists independently of the kind of geographic distribution and the ability of dispersal of the different populations. Similarity at CHC profiles appears to be a trait imposed by natural selection for the interaction between hosts and slave-makers. 1. Introduction Slave-making ants are a type of permanent social parasites (thus depending on enslaved hosts ants throughout their whole live) whose newly mated queens need to usurp a host nest in order to initiate a new parasite colony. Then the host brood will turn into slaves working for the parasite species while parasite workers only concentrate on replenishing the labour force from neighboring host nests, a process called slave raiding (see reviews [1–4]). The slave-maker style of life imposes selection pressures to both parts, as frequent slave raids strongly affect host populations and on the other hand, invading a host nest by parasite queens is determinant for their survival (see [2, 5, 6]). In this sense the study of host-parasite systems allows the study of coevolutionary strategies. Within the subfamily Formicinae only two genera fit the previous definition of slave-makers: Polyergus and Rossomyrmex [5–7]. The species of the Formica sanguinea group are facultative slave-makers [8, 9]. Thus, in relation with the obligate slave-maker genera most of the published studies are focused on Polyergus biology (e.g., [10–15]) whereas the genus Rossomyrmex has received little attention, probably due to its geographic distribution and
Redox Activities and ROS, NO and Phenylpropanoids Production by Axenically Cultured Intact Olive Seedling Roots after Interaction with a Mycorrhizal or a Pathogenic Fungus

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0100132
Abstract: Roots of intact olive seedlings, axenically cultured, were alternatively placed in contact with Rhizophagus irregularis (mycorrhizal) or Verticillim dahliae (pathogenic) fungi. MeJA treatments were also included. In vivo redox activities in the apoplast of the intact roots (anion superoxide generation, superoxide dismutase and peroxidase activities) were measured. All our results showed that apoplastic redox activities of intact seedling roots in contact with the compatible mycorrhizal fungus were clearly attenuated in comparison with the pathogenic fungus or treated with MeJA, even at the early stages of treatment used. Total phenolics, flavonoids and phenylpropanoid glycosides were also quantified. Roots in contact with the mycorrhizal fungus did not enhance the biosynthesis of phenolic compounds with respect to controls, while those in contact with the pathogenic one significantly enhanced the biosynthesis of all phenolic fractions measured. Reactive oxygen species and nitric oxid accumulation in roots were examined by fluorescence microscopy. All of them presented much higher accumulation in roots in contact with the pathogenic than with the mycorrhizal fungus. Altogether these results indicate that intact olive seedling roots clearly differentiated between mycorrhizal and pathogenic fungi, attenuating defense reactions against the first to facilitate its establishment, while inducing a strong and sustained defense reaction against the second. Both reactive oxygen and nitrogen species seemed to be involved in these responses from the first moments of contact. However, further investigations are required to clarify the proposed crosstalk between them and their respective roles in these responses since fluorescence images of roots revealed that reactive oxygen species were mainly accumulated in the apoplast (congruently with the measured redox activities in this compartment) while nitric oxid was mainly stored in the cytosol.

Abstract: MoccaDB is an online MySQL-PHP driven relational database that houses annotated and/or mapped microsatellite markers in Rubiaceae. In its current release, the database stores 638 markers that have been defined on 259 ESTs and 379 genomic sequences. Marker information was retrieved from 11 published works, and completed with original data on 132 microsatellite markers validated in our laboratory. DNA sequences were derived from three Coffea species/hybrids. Microsatellite markers were checked for similarity, in vitro tested for cross-amplification and diversity/polymorphism status in up to 38 Rubiaceae species belonging to the Cinchonoideae and Rubioideae subfamilies. Functional annotation was provided and some markers associated with described metabolic pathways were also integrated. Users can search the database for marker, sequence, map or diversity information through multi-option query forms. The retrieved data can be browsed and downloaded, along with protocols used, using a standard web browser. MoccaDB also integrates bioinformatics tools (CMap viewer and local BLAST) and hyperlinks to related external data sources (NCBI GenBank and PubMed, SOL Genomic Network database).We believe that MoccaDB will be extremely useful for all researchers working in the areas of comparative and functional genomics and molecular evolution, in general, and population analysis and association mapping of Rubiaceae and Solanaceae species, in particular.Accumulation of available genetic markers directly contributes to advances in marker-assisted genetic studies with a wide range of applications such as detection and identification of individual genes and/or quantitative trait loci (QTL), or exploration of the genetic diversity and population structure with regard to natural variations [1-3]. The recent and rapid accumulation of sequence resources, mainly from crop species, ensures an improvement of the genetics approach in combination with the comparative genomics. The extension of
