Pinaceae fue la más diversa (8) seguida de Asteraceae (9). La densidad (500-1,330 ind. ha-1), los tallos (650-3,040 ind. ha-1), la cobertura (10,999-4,6390 m2ha-1), el DAP (9.2-18.9 cm), la altura (6.5-12 m) y la riqueza (6-17) varían entre parcelas. El 75 % del área basal (20.1 m2 ha-1) fue aportada por los pinos, los encinos contribuyeron con el 14 % (3.6 m2 ha-1) y el 11 % fue de otras especies (2.9 m2 ha-1). \u0000Conclusiones: Los ecosistemas forestales del parque mantienen propiedades ecológicas características de los bosques templados del CVTM.

The most frequent species are respectively Salvia officinalis L., Trigonella foenum-graecum L. and Rosmarinus officinalis L. The most frequent families are respectively Lamiaceae, Asteraceae and Fabaceae. Seven new vernacular names have been listed. Most of the plants were spontaneous (55.9 %). The comparative analysis with previous work led to obtaining a checklist of 202 taxa (75 families) of which 65 have specific endemism and 77 (48 spontaneous) are on the red list.

Species of this family possess unusual morphological and reproductive characters, grow attached to rocks in rivers with strong currents, and have a life cycle tightly linked to seasonality. Due to its reduced floral structures, which characterizes most species, the analysis of developmental stages and events such as anthesis or stigma receptivity has proven difficult. \u0000Question: How floral morphology, floral development and stigma receptivity of different stages of flower development of Marathrum rubrum Novelo & C. T. Philbrick are related among them? \u0000Studied species: Marathrum rubrum Novelo & C. T. Philbrick. \u0000Study site and dates: Horcones River, Jalisco, Mexico. January, 2014 and 2015. \u0000Methods: We made an in situ and lab analyses of flower morphology to assess the relationships between flower morphology, stages of development, reproductive structures, and stigma receptivity, during different stages of flower development. \u0000Results: When flowers emerge from the spathella, both the ovules and pollen grains are fully developed, implying that sporogenesis and gametogenesis take place within the stem while the plant is still submerged. \u0000Conclusions: The morphological changes observed in the flowers of M. rubrum during the analyzed stages are related only to events associated with fertilization and fruit development. The time-course of morphological changes in the flowers, from anthesis to fruit formation, lasts 20 to 30 days. The detailed observation of the aerial reproductive biology of M. rubrum bears important implications to the genetic structure of populations, plant fitness and conservation biology in threatened environments.","PeriodicalId":503365,"journal":{"name":"Botanical Sciences","volume":"34 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140673122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, understanding the patterns and drivers of post-fire regeneration is essential to designing restoration proposals. \u0000Hypotheses: After a high-severity fire, we expected greater species richness and abundance of individuals in flat sites than in hillside sites since seeds, nutrients, and organic matter accumulate in flat landforms. Compared to some Pinus species, Quercus species are more drought-tolerant after a forest fire and, therefore, they are expected to dominate post-fire chronosequences. \u0000Study site: The study was conducted in the “La Primavera” Flora and Fauna Protection Area. \u0000Methods: We sampled vegetation and microenvironmental variables from 2021 to 2022 at 18 sites located on flat and hillside areas, at 3, 9, and ≥ 20 years since the last high-severity forest fires (TSF). \u0000Results: The richness of woody and herbaceous species was higher at 3 TSF and 9 TSF. The topographic condition did not significantly drive the richness and abundance of woody species, but richness and abundance of herbaceous species were significantly greater in flat sites. The oak tree Quercus resinosa Liebm. was the dominant species throughout the chronosequence. \u0000Conclusions: Quercus resinosa represents a foundational species for recovering forest structure and composition.

Mimosa acantholoba var. eurycarpa is a highly dominant species in the tropical dry forest in Mexico. \u0000Hypothesis: Mimosa acantholoba var. eurycarpa exerts an inhibitory effect on the germination, establishment, survival, and early growth of light-demanding pioneers, while facilitating these processes for shade-tolerant old-growth forests species. \u0000Studied species: Lonchocarpus torresiorum, Lysiloma divaricatum, Mimosa acantholoba var. eurycarpa and Vachellia farnesiana. \u0000Study site and dates: Nizanda, Oaxaca, Mexico, 2020-2021. \u0000Methods: In 12 early successional plots, we applied three levels of crown cover removal (100, 50, and 0 %) of established trees of the dominant pioneer legume (M. acantholoba var. eurycarpa). We sowed seeds of the four study species in each experimental plot and recorded their germination, establishment, survival, and early growth over a 2-mo period. \u0000Results: The removal of crown cover of established M. acantholoba var. eurycarpa trees did not significantly affect germination. Lysiloma divaricatum had the highest germination probability, the fastest germination, and the highest establishment probability regardless of treatment. Lonchocarpus torresiorum had the highest establishment probability in plots where the crown cover of established M. acantholoba var. eurycarpa trees was removed The survival probability of both shade-tolerant species was highest in the 100 % removal treatment. \u0000Conclusions: Despite successful germination of shade-tolerant species, their survival is inhibited under the dense canopy of the dominant legume.
