Summary: This study observed the effect of storage and pre-germination treatments on the germination of Arbutus xalapensis seeds. The results showed that the germination rate of the seeds decreased over time and the time required for germination increased. Pre-germination treatments with gibberellic acid helped reduce the time required for germination, but did not significantly increase the germination rate.

Summary: This study elucidated the combined effects of light and temperature on dormancy release and germination of Pinus koraiensis seeds. It was found that at optimum temperatures, light facilitated seed germination and increased germination percentage and germination value.

Summary: The research aimed to understand the diversity of cacti in northern Zacatecas and southern Coahuila and explore species rarity, environmental relations, and conservation alternatives. A total of 45 species were found, with 7 new records for Zacatecas, 2 for Coahuila, and 3 for both Mexican states. The Ar index was introduced as a tool for measuring species rarity and proved to be an effective and balanced method for assessing rare species in different environmental conditions.

Summary: This study aimed to investigate the seed germination of Berberis koreana Palibin. The results showed that the weight of the seeds increased significantly in 24 hours. Analysis of the seed's morphology revealed that the embryo was fully grown and did not grow further. Cold stratification for different lengths of time resulted in varying germination percentages. The GA3 treatment had limited effect on seed germination. The study concluded that B. koreana exhibits intermediate physiological seed dormancy.

Summary: Climate models predict further reduction in warm season precipitation and more frequent droughts across Mexico in the 21st century. The research evaluates different influences on groundwater in two basins with similar geological settings, with one mainly recharged by tropical storms and the other by both early and late summer rainfall. Factors such as CO2 partial pressure and recharge seasonality affect the salinity of groundwater in the region.

Summary: Rock varnish is a thin layer that coats rock surfaces in the northern Mexican deserts, and has been used by ancient human groups to record different types of motifs. This study explores the chemical composition and interaction between varnish and underlying rock, finding similarities in the composition but differences in the contact between the two. The main component of varnish is derived from aeolian deposition.

Summary: The study assessed and validated long-distance corridors for black bears in the southern distribution by using resistance models, occurrence records, and radio-telemetry data. It identified connectivity core areas and important corridors through Natural Protected Areas, emphasizing the need for monitoring dispersal individuals to understand the plasticity of organisms and the barriers they face.

Summary: The data set covers a 101-year period of plant sampling in the Jornada Experimental Range in southern New Mexico. It includes various data formats such as digitized maps, species coordinates, species counts, and environmental characteristics, providing a unique opportunity to study the changes in vegetation over a century of varying environmental conditions.

Summary: Seeds and seedlings are crucial stages in the life cycle of cacti, relying on facilitation by nurse plants for successful recruitment. Research found high germination rates for seeds under laboratory conditions, but germination only occurred under specific nurse plants, with age and protection against herbivores increasing seedling survival rates.

Summary: Vegetative propagation and tissue culture are currently the only options for cultivating Miscanthus spp., but a preliminary study on the seeds of hybrids obtained through cross-pollination shows that they can be a valid alternative. The germination of the seeds decreased significantly after storage for 1 year at room temperature or 8 degrees C, indicating dormancy. However, the use of gibberellic acid (GA(3)) solution can improve seed germination.

Summary: This study investigated the germination characteristics of 24 grass species and found that several species have the potential for rapid establishment in arid zones, including Eragrostis curvula, Bouteloua curtipendula, Leptochloa dubia, and Digitaria californica. However, invasive species E. lehmanniana and Melinis repens may have other strategies to facilitate their establishment.

Summary: This study evaluates the variability of precipitation, vegetation, and groundwater relations in a semiarid rangeland setting in northern Mexico. Soil and water conservation practices were conducted from 2012 to 2014, followed by the monitoring of hydrologic variables since 2014. The study shows that the conservation practices have positively affected vegetation conditions and groundwater levels, with an upward trend observed in the post-treatment years.

Summary: Research suggests that shrubs cultivate a distinct microbial community on the leading edge of the invasion, which may be necessary for shrub colonization, establishment, and persistence. This indicates a strong influence of plant-microbial interactions on plant success during the process of shrub encroachment in grasslands.
