“…It should be noted that the areas further away from the sea are more continental than those that are closer to it and are, therefore, attenuated by its influence. This is in line with previous research, which found a positive trend in the index in a large part of the state, with the exception of most coastal areas [124].…”

“…Increasing maximum temperature, coupled with a general decrease in rainfall in the state [6], pose a threat to the survival of the northern populations of this tree [123]. This is consistent with previous research on trends in summer ombrothermic indices [124], which shows a negative trend in the indicated areas and the current habitat of this species [121]. The result is also in line with other research indicating a water balance deficit during the summer months for A. magnifica [33].…”

“…In the north of the state, it is mainly found to the west of Cedarville and in the surrounding areas of Mount Shasta and Klamath National Forest (North and Central California Province). Losses in these areas are mainly due to the change in the continentality index, especially the increase in values as found for these areas in other studies [124].…”

“…This index expresses the difference or thermal oscillation between the warmest and the coldest month of the year. In other words, the higher the value of Ic, and, therefore, the greater the temperature difference over the year, the more continental the area [124]. As described in the previous sections, this species is characterised by its occurrence with a strong influence of the ocean.…”

Rising temperatures and changes in precipitation patterns under climate change scenarios are accelerating the depletion of soil moisture and increasing the risk of drought, disrupting the conditions that many plant species need to survive. This study aims to establish the bioclimatic characterisation, both qualitative and quantitative, of ten native Californian Pinales for the period 1980–2019, and to determine their habitat suitability by 2050. To achieve this, an exhaustive search of the Gbif database for records of ten conifer taxa was carried out. To conduct the bioclimatic characterisation of the studied taxa, we worked with the monthly values of average temperature and precipitation for the period 1980–2019 from 177 meteorological stations. Linear regressions was performed in order to compile the future evolution of California’s climate. Suitable areas and optimal areas were defined at the present time (1980–2019) and its future projection (2050). We applied Boolean logic and, in this investigation, the Conditional Logic Operator (CON) was used to determine the possible species presence (one) or absence (zero) for each of the 15 variables analysed. In general, most of the conifers studied here will experience a reduction in their habitat range in California by the year 2050 due to climate change, as well as the displacement of species towards optimal areas. Furthermore, the results have highlighted the applicability of bioclimatology to future conditions under climate change. This will aid conservation managers in implementing strategic measures to ameliorate the detrimental impacts of climate change, thereby ensuring the ecological integrity and sustainability of the affected conifer species.

“…Animal associations with foundational plant species increase substantially when an environment exhibits climatic extremes that require external methods for amelioration (Holmgren & Scheffer 2010). Arid desert ecosystems within Southern California span climatic extremes through frequent drought events in time and across space regionally with extremely low annual precipitation and relatively high temperatures (Reynolds et al 1999; Gols et al 2021; González‐Pérez et al 2023). However, there are various microclimates within these arid ecosystems, such as those created by naturally occurring shrubs, that contribute to the environmental heterogeneity within an ecosystem (D'Odorico et al 2010).…”

Facilitative associations between the foundational shrub species Ephedra californica and local vertebrate species can drive positive interactions within desert ecosystems that influence diversity and assembly processes. These foundational shrubs can contribute to the structural heterogeneity of ecosystems for plants and animals including variation in temperature profiles, refuge from predation, and habitat for foraging. Artificial structures can also influence fine‐scale ecological and micro‐environmental dynamics. We tested the hypothesis that artificial shrubs (mimics) positively influence desert vertebrate association through facilitative interactions, similar to foundational shrub species. Mimics were deployed at four distinct sites within the central deserts of Southern California. A combination of camera traps and temperature pendants were utilized to measure the association patterns of vertebrate species and the microclimatic variation at mimic, open, and shrubs. A total of 21 species were observed in this study. Mimics had a significantly higher vertebrate abundance and richness than open microsites and functioned similarly to shrubs. These findings suggest that mimics can be utilized as a stop‐gap replacement for foundational shrub species as they can act as a novel fine‐scale habitat for many desert vertebrate species.

Aims: The task of classifying and naming Mexican vegetation types has been undertaken by previous botanists, ecologists, and mapping agencies. However, discrepancies remain due to the lack of criteria and joint efforts from a geographical and botanical perspective. We aim to unravel the complex interactions between climate and vegetation in Mexico using climatic data and advanced mapping techniques, display in maps the transition from land cover to vegetation maps and couple geobotanical and bioclimatological approaches to provide a sound, unified system for identifying Mexican bioclimatic physiognomic patterns. Methods: Bioclimatic mapping was developed from the Digital Climatic Atlas of Mexico data source. In addition, land cover and vegetation data were obtained from the National Institute of Statistics and Geography of Mexico regrouped as described by the Standardized Hierarchical Vegetation Classification. These data were analysed via standard map crossing technics using geographic information systems. Results and conclusions: The results revealed five ombrotypes and five thermotypes, leading to the identification of 13 different bioclimatic classes, which, when combined with physiognomic types, led us to recognize 11 forests, 3 shrublands and 3 herbaceous formations (at a scale of 1:4,000,000). The core outcome is a detailed bioclimatic/physiognomic vegetation map including forests, shrublands and areas dominated by Herbaceous/Non-Vascular formations. The map highlights the critical importance of harmonising methodologies to ensure comprehensive and accurate insights into Mexico’s bioclimatic diversity. Taxonomic reference: Villaseñor et al.
