“…The minimum number of points was set to 5 and the standard deviation of the aggregation area ellipse was set to 1X; that is, approximately 50% of the points were included in the aggregated ellipse. The threshold is calculated by the random nearest neighbor distance method, and the mathematical model is shown in Equation (5).…”

“…Vegetation is a key biosphere component in supporting Earth's biodiversity and affects many important ecosystem services, including biodiversity protection, water conservation, climate regulation, and carbon storage [5][6][7]. Vegetation, as an important part of the SRYR, can not only respond to climate change in the SRYR, but also reflect the change in the ecological environment.…”

Studying the variation in vegetation types within the source region of the Yellow River (SRYR) is of great significance for understanding the response of vegetation to climate change and human activities on the Qinghai-Tibet Plateau (QTP) permafrost. In order to understand the characteristics of the variation in vegetation associations in the SRYR under the influence of climate and human activities, two hyperspectral remote sensing images from HJ-1A in 2013 and OHS-3C in 2020 were used to extract the vegetation types located in the area south of Ngoring Lake, covering 437.11 km2 in Maduo County, from the perspective of vegetation associations. Here, the hybrid spectral CNN (HybridSN) model, which is dependent on both spatial and spectral information, was used for vegetation association classifications. On this basis, the variations in vegetation associations from 2013 to 2020 were studied using the transition matrix, and the variation in noxious weeds across different altitude and slope gradients was analyzed. As an example, Thermopsis lanceolata’s spatial distribution pattern and diffusion mechanism were analyzed. The results showed that (1) in addition to noxious weeds, herbage such as Poa poophagorum, Stipa purpurea, Kobresia humilis, and Carex moorcroftii increased, indicating that the overall ecological environment tended to improve, which may be attributed mainly to the development of a warm and humid climate. (2) Most of the noxious weeds were located at low altitudes with an area increase in the 4250–4400 m altitude range and a decrease in the 4400–4500 m altitude range. More attention should be given to the fact that the noxious weeds area increased from 2.88 km2 to 9.02 km2 between 2013 and 2020, which was much faster than that of herbage and may threaten local livestock development. (3) The Thermopsis lanceolate association characterized by an aggregated distribution tended to spread along roads, herdsmen sites, and degraded swamps, which were mainly affected by human activities and swamp degradation.

“…For centuries, vegetation ecologists have pursued the goal of understanding the roles of the multiple abiotic and biotic factors affecting the vegetation of Earth. In their contribution, IbarraManríquez et al (2022) reflect on the difficulties and opportunities to accomplish this objective and review relevant advances in the main areas of vegetation ecology. After delving into theoretical and methodological challenges, including potential solutions and alternatives, the authors claim that vegetation ecology, currently turned into a scientific discipline on its own, will continue to play a key role in the construction of new knowledge necessary to strengthen the theoretical and technological tools required to address the urgent need to conserve the vegetation cover of the planet.…”

As in every field of scientific research, publication of new findings is a fundamental task of botanical investigations. Since its launching in 1944, Botanical Sciences (formerly Boletín de la Sociedad Botánica de México), the scientific periodical of the Botanical Society of Mexico, has played a major role in the dissemination of botanical knowledge, with a strong emphasis on Mexican plants and vegetation. In this essay, whose preparation was propelled by the publication of the 100th Volume of Botanical Sciences in 2022, we revisit this scientific periodical’s trajectory for almost eight decades of activity, during which it has become an honorable member of an international assembly of journals devoted to publishing research in all botanical subdisciplines. On this ground, we reflect on its future, pondering the challenges it faces, the need to adjust to emerging circumstances, and the opportunities created by current national and international editorial practices. Additionally, we provide a brief overview of the contents of the contributions included in this Special Issue, with emphasis on the main conclusions drawn by their authors. We hope that these articles will become key references guiding future work in their respective botanical subdisciplines.

“…Several studies have highlighted the different attributes of tropical vegetation on limestone outcroppings pinpointing their differences with communities typical of other substrates (Ibarra-Manríquez & Martínez-Ramos 2002, Pérez-García & Meave 2005, Pérez-García et al 2009, Ibarra-Manríquez et al 2022. In these particular communi-ties the role of smaller-scale environmental factors (microclimatic, topographic, and edaphic), as well as a large array of natural and anthropic disturbances determine the variable composition and structure of plant communities influencing the variability of the vegetation (Ibarra-Manríquez & Martínez-Ramos 2002, Do et al 2015, Méndez-Toribio et al 2016, Sánchez-Reyes et al 2021, Ibarra-Manríquez et al 2022.…”

Background: One of the most diverse and threatened plant associations in the Yucatan peninsula has not been characterized and therefore not included in any protection category in Mexico. We characterize and describe this plant association, which is rapidly disappearing or being irreversibly transformed as a result of anthropic activities. We propose a name and attempt a preliminary assessment of its taxonomic richness, and the identification of priority species to be preserved. Questions: What is the species richness and plant endemism associated within this plant association? What are the ecologically important and high-priority species for conservation? How is it different from associated or similar plant associations? Studied species: Vascular plants. Study site and dates: Northern Yucatan peninsula; 2021-2023. Methods: The plant association was characterized, and quantitative parameters were recorded. The Importance Value Index was estimated to assess its local ecological importance, and each species was assigned a conservation category in order to evaluate the conservation status in a global context. Results: We propose Seasonally flooded Coquinal (SFC) as a name for this plant association based on geomorphological, physiognomic, and structural attributes. A total of 206 species were recorded, which two are endemic to the SFC and 28 to the Yucatan Peninsula Biotic Province (YPBP). Twelve species are listed under a risk category. Conclusions: The SFC harbors a high plant diversity of endemic species to the YPBP, 12 of which are included in the IUCN red list, for which its typification and conservation should be a high priority in Mexico.
