Termites are important insects due to their participation in the decomposition of organic matter and the recycling of nutrients in the soil, however, some species cause damage to buildings, forest plantations and agricultural crops, where they cause significant losses. The objective of this study was to make an annotated list with identification keys for the termite species present in agroforestry and relict forest systems in the State of Tabasco, Mexico. The collection of termites was carried out in 20 sites distributed in the main forest areas of Tabasco, Mexico. The sampling was directed selecting 15 transects of 10x50 m for each type of vegetation. Eight species of termites were identified of which Nasutitermes nigriceps (Haldeman, 1854) and N. corniger (Motschulsky, 1855) were present in all forest areas, followed by Coptotermes testaceus (Linnaeus, 1758) and Heterotermes convexinotatus (Snyder, 1924). The species Microcerotermes septentrionalis Light, 1933, Tenuirostritermes briciae (Snyder, 1922), Cahuallitermes intermedius (Snyder, 1922), and Incisitermes snyderi Light, 1933 were only collected from one locality. The species T. briciae and M. septentrionalis are reported as new records for Tabasco.

El decremento en las poblaciones naturales y manejadas de polinizadores ha situado el interés sobre el papel de los polinizadores, principalmente en el sector agrícola, por los efectos reportados en lo que se conoce como la “crisis de los polinizadores”. Dentro de los polinizadores más representativos se encuentran las abejas, y dentro de éstas, las abejas sin aguijón (Apidae: Meliponini). Estas últimas tienen gran relevancia ecológica, económica y cultural en el mundo y particularmente en México, por ser un grupo manejado desde hace cientos de años para obtención de miel y otros productos de la colmena. En esta revisión de literatura nos enfocamos en documentar lo que se sabe sobre las abejas sin aguijón en cuanto a su distribución, genética y ecología. En particular nos interesa resaltar aspectos sobre sus interacciones y los servicios ecosistémicos que proveen. Nuestro objetivo fue sintetizar la información disponible para México e identificar áreas de oportunidad en el estudio de estas abejas, con el fin de promover mejores estrategias de conservación y manejo. Encontramos que falta intensificar los estudios de este grupo para poder realizar un análisis de cómo los cambios ambientales afectan la riqueza de especies, abundancia, distribución e interacciones. Así mismo, la falta de estudios longitudinales nos impide conocer la magnitud del declive de estos polinizadores. Finalmente, proponemos incluir en los estudios de ecología y genética de abejas sin aguijón un enfoque de participación social, la cual puede proveer información muy valiosa sobre abejas nativas en México.

Los hemeróbidos tienen una distribución cosmopolita y destacan por sus hábitos entomófagos sobre insectos pequeños de cuerpo blando. En México, la especie Sympherobius barberi (Banks, 1903) se registra en Baja California, Estado de México Guanajuato, y Morelos. El interés sobre su potencial uso comercial como agente de control biológico en el país motivó la revisión de esta especie. Tanto en publicaciones científicas como en bases de datos y colecciones biológicas, se documentan los caracteres taxonómicos requeridos para determinar esta especie y se propone sustituir la taxonomía básica basada en patrones de manchas alares. Además, se reporta nueva información sobre presas y plantas hospederas: Brevicoryne brassicae (Linnaeus, 1758) en Brassica spp.; Dactylopius confusus (Cockerell, 1893) en varias especies del género Opuntia y Nopalea cochenillifera; Dactylopius opuntiae (Cockerell, 1896) sobre Opuntia ficus-indica; Phenacoccus solenopsis Tinsley, 1898 en algodón; Planococcus ficus Signoret, 1875 en vid; y larvas de Plutella xylostella (Linnaeus, 1758) en brócoli.

The article comments on the first legal regulation of the social agreement in the Community of Madrid, within the framework of the new Act 12/2022, of 21 December, on social services of the Autonomous Community of Madrid.

Since the adoption of the Statute of Autonomy, the Galician Autonomous Community has faced the responsibility of drawing up and developing its own external action strategy in accordance with its interests, taking advantage of all the minimum and maximum possibilities of developing political autonomy, despite the limited statutory provisions in this regard. This external action has been enhanced by the European, Atlantic, and cross-border dimension of Galicia. In this context, the development phases of the Galician External Action have followed an ascending and well-defined line...

The book The demon in Democracy: Totalitarian Temptations in Free Societies of Ryszard Legutko is having impact on the current Spanish conservative thought. However, the author of this paper thinks that Legutko’s analysis isn’t right. On the one hand, the analysis is very simplistic. On the other hand, Legutko ignores the influence of the technique on post-WWII Western political systems. Our text analyzes and comments the Legutko’s book. We do the gloss from the texts of three authors: Manuel García-Pelayo, Ernst Forsthoff and Pierre Legendre...

Strengthening sufficiency and financial levelling within the framework of the powers assumed by the Autonomous Communities was one of the main objectives of the last reform of the Regional Financing System fourteen years ago. Throughout this work, the results of this current model of decentralisation of public services and regional financing are analysed and evaluated, with special reference also to its effects in terms of solidarity between territories...

COVID-19 involves many changes in traditional economic structures, which do not go unnoticed by the Galician economy. Once the health crisis is over, it is necessary to clarify the immediate economic consequences and, above all, to highlight the opportunities that arise for our productive sector to adapt to this new reality, in particular the use of European Recovery, Transformation and Funds. Resilience (Next Generation EU Funds). The need to adapt to the changes resulting from COVID-19 and the allocation of European funds leads to the emergence of many opportunities in all productive sectors. The aim of this article focuses on analyzing the opportunities for economic recovery in industry, energy, environmental technologies and digitalization.

The Spanish decentralisation process was the result of ideologically non-coincidental and sometimes even conflicting tendencies which meant that the final implementation of the constitutional provisions depended to a large extent on political decisions and party pacts which, on more than one occasion, resulted in regulatory changes of unquestionable importance. The process that led to the approval of the Galician Statute and the constitution of the corresponding Autonomous Community was, as this text aims to explain, an outstanding example of the aforementioned twists and turns: Galicia should have gained access to autonomy through a privileged route that at the time, although unsuccessfully, attempted to denaturalise itself...

Galicia stands out as a key reference point for the most advanced new scientific production. This achievement, after a long period of political and cultural ostracism, led to a political and social process of action for a common social good: the recognition of Galician culture, the generation of its own institutions and a political-administrative framework of multilevel governance. Currently, the term Galicia is interrelated with an incremental and first level interdisciplinary scientific knowledge. Scopus, in the Galician autonomous process, has been an ally for the international projection of the scientific knowledge of the Galician community. Within this framework, the study presents an analysis and dissemination of part of the main scientific production that refers to Galicia with express titles.
