Las hormigas y los pulgones mantienen relaciones mutualistas, en las que ambas especies se benefician de la interacción mutua. Ahora un estudio multidisciplinar realizado en España en el que ha participado el Consejo Superior de Investigaciones Científicas (CSIC) ha descubierto, que de forma paralela al mutualismo, entre estas dos especies se produce también otro tipo de relación en la que el pulgón se aprovecha de la hormiga y la perjudica potencialmente. Los resultados del trabajo han sido publicados en la revista Proceedings of the National Academy of Sciences (PNAS).
En la simbiosis entre hormiga y pulgón, el pulgón recibe cuidados y protección de la hormiga que, a su vez, se ve recompensada con la melaza que excreta el pulgón. En este estudio hemos visto que algunos individuos del pulgón Paracletus cimiformis imitan las sustancias emitidas por las larvas de la hormiga Tetramorium, de manera que las hormigas creen que son sus crías y los transportan hasta las cámaras ‘guardería’. Una vez allí, el pulgón succiona la hemolinfa, el equivalente a la sangre en los artrópodos, de las larvas de hormiga”, explica la investigadora del CSIC Carme Quero, del Instituto de Química Avanzada de Cataluña.
Se trata de la primera vez que se describe una relación de este tipo entre áfidos (pulgones) y hormigas, en la que un comportamiento agresivo por parte del pulgón hacia la hormiga coexiste con la estrategia convencional de mutualismo entre estas dos especies. En este caso, los investigadores han observado que los pulgones de tipo redondo llevan a cabo la relación convencional, beneficiosa para ambos, mientras que los de tipo aplanado muestran hacia la hormiga el comportamiento agresivo descrito más anteriormente.
Todo lo descrito añade una nueva dimensión a la clásica relación hormiga-pulgón y muestran un sistema complejo que plantea nuevas cuestiones a nivel evolutivo en la transición entre cooperación y explotación”, añade Quero.
Además del CSIC, en el estudio han participado el Institut Cavanilles de Biodiversitat i Biologia Evolutiva, perteneciente a la Universitat de Valéncia, y la Universidad de León.
Después de un magistral partido contra la nº 1 del mundo Iga Swiatek, la bielorrusa Aryna Sabalenka gana el Mutua Open de Madrid 2023. El espectáculo tenístico de las dos jugadoras mejores del mundo ha sido soberbio. Enhorabuena a ambas deportistas.
La nueva estrella del tenis femenino español. Es muy buena y guarda cierto parecido con la legendaria María Sharapova. Hoy disputa las semifinales del Master 1000 de Madrid, primera competición con público desde la pandemia, a la numero uno del mundo, la australiana Ashleigh Barty.

Best Wishes to all who visit my photostream. Thank you for all the comments over the last 12 months, they are always very much appreciated.
This Ptarmigan (Lagopus mutus) was photographed in the Scottish Cairngorms a little while ago.
Male Ptarmigan showing very well on Glen Shee.
A special moment, as my first ever sighting of this species.
After searching for Ptarmigan on several mountain tops, it was a relief to find a small group of 3 on Glen Shee, on our last morning before we had to leave Scotland by early afternoon. Very much a last minute success!!

In questo caso si tratta della femmina albina di anatra mandarina (Aix galericulata) con quello che rimane della sua nidiata ... due piccoli

Eri Hozumi es una tenista japonesa, especialista en dobles, que jugó en el último Torneo de Tenis Mutua Open de Madrid. Esta foto se la hice minutos antes de que se fuera la luz en Madrid, el día del apagón, el pasado día 28 de abril. Me encanta su cara de concentración buscando la bola antes de impactarla con su raqueta.

A male Rock Ptarmigan (Lagopus mutus) were frequently observed on the tundra near our camp. They have a very distinctive call which we noted upon our arrival at Karrak Lake, Nunavut.
As noted before, the birds were quite tame and allowed us some good photographic opportunities. Kodachrome 64 slide film was our only film type and I recently had the slide digitally scanned for use on this site.

The Rock Ptarmigan (Lagopus mutus) was also observed in the McConnell River, Nunuvat area.
It was also delightful to come across these special creatures which appeared to be scattered across the tundra landscape.
Our field camp was south of the community of Arviat along the west coast of Hudson's Bay.
It was photographed using Kodachrome 64 slide film.

A Rock Ptarmigan (Lagopus mutus) on the grassy tundra landscape near our field camp at Karrak Lake, Nunavut.
The males do change in plumage during the breeding season but the ones we encountered were still in the white winter plumage.
Images were captured on Kodachrome 64 slide film.

We normally see a few of them but he was the only one this time.

Sobre la esquina de la calle de la Av.Entre Rios y Alsina, se impone un edificio de arquitectura fastuosa rematado con una cúpula, construido por arquitectos franceses para la Asociación Española de Socorros Mutuos, fuerte en este barrio por la gran cantidad de inmigrantes españoles instalados a comienzos del siglo XX. En la actualidad, aloja oficinas del Congreso Nacional y su Biblioteca
On the corner of the street of the Av.Entre Rios and Alsina, imposes a building of lavish architecture topped with a dome, built by French architects for the Spanish Association of Mutual Aid, strong in this neighborhood by the large number of Spanish immigrants installed at the beginning of the 20th century. Currently, it houses offices of the National Congress and its Library.

Nonostante il mutuo scambio di dotazioni fra DB ed SBB Cargo si sia formalmente concluso agli inizi del nuovo anno con l'implementazione del sistema di sicurezza ETCS sulle prime Br185 delle ferrovie tedesche, almeno fino a fine gennaio è stato ancora possibile avvistare alcune locomotive delle SBB incaricate di trainare verso l'Italia convogli normalmente in carico al gruppo DB Schenker.
Ecco quindi uno dei "classici" del San Gottardo, il Winnerzug da Wuppertal per Piacenza iniziare l'ascesa verso Goeschenen al traino di un Re10/10 in luogo delle classiche TRAXX tedesche. (22/1/16)
Sculpture by Wangechi Mutu at the Legion of Honor in San Francisco. One of two powerful sculptures of hybrid goddesses that are part animal, part woman, and part alien. The exhibit will be open until 7 November 2021.
Happy weekend! Thanks, as always, for stopping by and for all of your support -- I greatly appreciate it. Take care and stay safe!
