Background and aims: In this work, the ferns and lycophytes of the Paisaje Protegido Cerro Mbororé, Oberá, Misiones, Argentina are studied. The phytogeographic importance of the area is discussed, since it is located in the transition between the District of the Mixed Forests and the District of the Fields, in the Amazonian Domain from the country. M&M: The collected materials were deposited in the LP, BA, and SLP herbaria. For the identification of species, the Flora Argentina and local floras were used. The photographs taken in the field were uploaded to the iNarulatist platform. The herbarium specimens studied are mentioned in this section. Results: The study area has 32 species of ferns (nine families) and one species of lycophytes. The most diverse family is Pteridaceae, with six genera and 13 species, followed by Polypodiaceae, with three genera and four species. Four well-defined environments with particular associations of species are identified: the top of the hill, the high-altitude lagoon, the north slope and the south slope. Conclusions: The environmental heterogeneity, product of the steep relief, and the transitional position of the area, generate a complex community of ferns and lycophytes with an important environmental value, which must be protected from the danger of the advance of the agricultural frontier and forestry exploitation.

The aim of the paper is to determine the effect of extreme wealth on economic development (human development index and sub-indices) in 64 countries during 2005-2018, with special emphasis on Mexico and China. A dynamic estimation (sys-GMM) is followed. Estimations show that extreme national wealth acts as a constraint on human development for the entire sample of countries, including Mexico and China. Income is found to be most sensitive to this type of wealth, followed by the education index. The analysis confirms that democracy, economic freedom, investment and social spending are underlying factors of HDI. [ABSTRACT FROM AUTHOR]

This paper shows how Plan S arises and works, the impact it can have on the subscriptions of the scientific and academic journals of the National Autonomous University of Mexico (UNAM), as well as the first approaches of some publishers who see in this University and Latin America an opportunity to implement this new publication model. The way of publishing has changed due to the use of technologies that have brought with it the emergence of the Open Access (OA) movement derived from the Budapest Open Access initiative proposed by the Open Society Institute in 2001. Plan S is an initiative that arises in 2018 to accelerate the transition to Open Access, which will allow research results to have greater visibility and citation. Plan S includes transformative agreements that can be established between publishers and libraries, since it is intended to change the payment for subscription to journals for the Read and Publish model, where the publisher receives a payment to read and a payment to publish in a single contract, while under the Publish & Read model the editor only receives payment for the publication of articles by authors from an institution and the reading of journals is included at no additional cost, precisely at this point, the library plays a relevant role among the initiative and its academic community. Therefore, we agree that Plan S, the cOAlition S initiative and the transformative agreements are a great support for open access publishing, since they directly lower the costs of the Article Processing Charges (APC) and offer researchers various options for publish their findings or advances.

Introduction: Ants fulfill important ecological functions in many ecosystems and are highly sensitive to changes in land use. However, the response to these changes is poorly documented, at large spatial scales and in different land uses, in poorly studied ecosystems such as the Serranía del Perijá. Objective: To analyze the richness, diversity, and composition of ant communities in four land uses of two agroforestry landscapes of the Serranía del Perijá, Cesar, Colombia. Methods: Two sampling windows of 4 × 4 km were delimited in two agroforestry landscapes (compensation and non-compensation). In each window and landscape four land uses were chosen: forests, coffee agroforestry systems, natural regeneration and pastures, in which two trapping methods were applied: Pitfall traps and Winkler bags. Six environmental variables were measured: canopy cover, leaf litter height, bulk density, temperature, humidity and soil hardness. The sampling effort was 384 Pitfall traps and 192 m2 of leaf litter extraction. The fieldwork was conducted between February and March 2021. Results: Ants showed high sensitivity to changes in land use. Species diversity and richness decreased in land uses with less natural vegetation cover, such as pastures; while forests, in both landscapes, retained the highest species richness. Canopy cover and leaf litter availability were the environmental parameters that favored the diversity and richness of ant communities in all land uses. No differences were found between the ant composition of the two landscapes studied. Conclusions: Ants respond to changes in land use, particularly to vegetation cover. Our hypothesis was confirmed since land uses with high vegetation cover were the habitats with the greatest richness and diversity of ants. Environmental heterogeneity, a product of the dynamics of landscape transformation, is an element that should be considered in future research. [ABSTRACT FROM AUTHOR]
